PHOSPHOR -BRONZE GERMAN SILVER THE RIVERSIDE METAL CO. RIVERSIDE, &. THE IRON AGE New York, Thursday, April 18, 1907. A Water Main Tapping Machine. A novel use for a small gas engine is its application to a tapping machine used for making connections with water mains. The Water Works Equipment Company, 180 Broadway, New York, recently built a machine capa- ble of making a 30-in. connection with a water main, which is operated by a 6%-hp. Mianus gasoline engine, and the innovation has proved so successful that the company is now equipping its tapping machines of various sizes with 30-in. gasoline engines for drive in place of hand power operation. The machine shown in the accompanying illustration was successfully used at Trenton, N. J., recently in mak- ing a connection without shutting off the water in the main, and it substantiated the contention that with these machines, branch connections of sizes ranging from small power The No. 4 Gasoline Engine Driven Tapping Machine for Making 30, 36, Company, Water Works Equipment ‘ones for domestic house service to a 48-in. branch can be made without shutting off the water. The machine and engine complete weighs about 5500 Ib. The engine is bolted to the frame of the tapping machine and the pinion on its shaft meshes a large gear operating a second pinion inside of the frame, which in turn drives the large gear exposed at the open side of the frame in the illustration. The latter gear is on the same shaft with a long pinion which meshes with a gear on the boring spindle and allows it to be shifted longitu- dinally as the feeding of the spindle progresses. The feeding of the spindle is accomplished by rotating the pilot wheel shown at the rear of the machine. At the cutting end of the boring spindle is a leading off drill, which guides a 4-in. cutter. The hole made by the latter is large enough to allow the shaft of the large cutter to be introduced, and a series of spring catches on the shaft serve to hold the piece of pipe after it is cut out by the -50-in, cutter. To tap a main under pressure a sleeve and valve are used. The sleeve is a special fitting of tee form, in which the cross or run of the tee is separable longitudinally on a central plane perpendicular to the side branch so that bolted the main to be tapped, with the point where the hole is to come covered by the side branch of the tee. it may be together, surrounding The valve is of any stand ard gate form, and is connected between the side branch and the flange of the machine. After the connections are made and the valve opened, the frame of the tapping tapping operation is carried on within the branch. In the Trenton a 1%-in. hole first cut in the main by the leading off drill and a 4-in. hole the small cutter, thus allowing the main shaft of the 30-in. cutter to be inserted in the pipe This cutter was then operated until the 30-in. hole was cut in the shell of the pipe. To cut the 1%-in. hole and the 4-in. hole took 30 min., and to cut the 30-in. hole took work as done at was was made by 42 and 4S In. Connections to Water Mains, Built by the New 7 York City. 59 min. During the whole operation 2% gal. of gasoline were consumed, which at 15 cents per gallon cost about 45 cents. When the piece of pipe cut out by the machine was removed past the gate, the latter was closed until the machine was detached and the outer end of the valve was then connected up with the branch line. The sleeve supplied by the Water Works Equipment Company special flanged joint for securing the halves together, and is arranged to use cement instead of lead for filling the bulk of the space between the cast iron sleeve and the main pipe. At the hubs or bells it is lead. The flanges, instead of having a full bearing against each other where they are bolted together, a space of triangular cross section between them. has a necessary to use sleeve touch only at the outside edges, leaving The joint faces are about 1% in. wide, and between them a \4-in. lead gasket is placed. When the bolts are tightened more pressure is brought upon the joint faces and the gasket than would be the if the full face of the flanges were in contact. case 1186 Open Hearth Steel in 1906. Total|jProduction, 10,970,998 Gross Tons, and ‘of All Kinds of Steel, 23,365,000 Tons. The American Iron and Steel Association has com- pleted the collection of the statistics of open hearth steel production in the United States in 1906. The total of open hearth ingots and direct castings was 10,970,998 gross tons, an increase of 1,999,622 tons, or 22.2 per cent, as compared with the figures for 1905, which were 8,971,376 tons. The production for 1906 was much larger than that of any other year, and was only 1,304,255 tons less than the Bessemer steel output last year—12,275,253 tons. General Manager James M. Swank estimates that when the statistics of crucible and miscellaneous steel in- gots and castings are completed it will be found that the total of all kinds of steel ingots and castings produced in this country in 1906 approximated 23,365,000 gross tons.

The production of basic open hearth steel in 1906 was 9,649,385 gross tons, and of acid open hearth steel 1,321,613 tons, while in 1905 the production by the basic process amounted to 7,815,728 tons and by the acid proc- ess to 1.155,648 tons. This is a gain in production in 1906 over 1905 by the basic process of 1,833,657 tons and by the acid process of 165,965 tons. In 1904 the produc- tion of basic open hearth steel was 5,106,367 tons and of acid steel, 801,799 tons. Pennsylvania made 68.4 per cent. of the total produc- tion of basic steel ingots and castings in 1906 and 83.6 per cent. of the total production of acid steel ingots and castings, against 70.3 per cent. of basic and 84.1 per cent. of acid ingots and castings in 1905. Lllinois and Ohio were the next largest producers of open hearth steel in each of these two years.

As compared with 1905, when 320,381 tons of castings were made by the THE IRON AGE April 18, 1907 acid process, the increase in 1906 by this process was 87,- 022 tons. By the basic process the increase was 99,595 tons, the production by this process in 1905 having amounted to 206,159 tons.

Active Open Hearth Works, The number of open hearth steel plants in the United States is growing. The open hearth steel made in 1906, including both ingots and castings, was produced by 124 works in 20 States, as follows: Massachusetts, 4; Connecticut, 3; Rhode Island, 1; New York, 8; New Jersey, 5; Pennsylvania, 61; Delaware, 1; Maryland, 1; West Virginia, 1; Georgia, 1; Alabama, 5; Ohio, 13; Indiana, 3; Illinois, 7; Michigan, 2; Wisconsin, 4; Mis- souri, 1; Minnesota, 1; Colorado, 1, and California, 1. West Virginia, Georgia and Minnesota made no open hearth steel in 1905, but all appear among the producers in 1906. One hundred and eleven works in 17 States made open hearth steel in 1905, and 116 works in 16 States made open hearth steel in 1904. —_—__——_>-@—____—_ Electricity at the Jamestown Exposition. Electric power for the approaching exposition at Jamestown, like that at the Buffalo Pan-American, will come from a distance. Having no Niagara to rely upon, however, power for the Jamestown Exposition will be furnished by steam turbines located in the power house of the Norfolk Railway & Light Company, about 7 miles from the exposition grounds. This fair will be the first at which the electric power will be generated by steam tur- bines. The machines will be of the Curtis type, these as well as the complete electrical equipment being supplied by the General Electric Company. The exposition authorities have entered into a con- tract with the Norfolk Railway & Light Company to furnish all the electricity required for illumination and power purposes. The electricity generated at the James- town power house will be transmitted on specially con- structed lines to a model substation in Machinery Hall. Here will be located the transforming and distributing apparatus. This equipment consists of large air cooled transformers and many smaller type H transformers for general illumination as well as constant current trans- formers for the series-arc lighting system, which will be used for police illumination. At the substation also are motor generator sets to provide direct current for the operation of searchlight. and small motors where they may be installed by exhibitors. ‘ The switchboard for controlling the various circuits throughout the exposition grounds is located in a gallery and is typical of modern switchboard engineering. All! the electrical machinery follows standard lines similar to that installed at St. Louis, the Pan-American and other expositions. Those who have seen the plans of the Jamestown Ex- position predict that the electrical features, particularly the illumination, will equal if not excel the display at the famous Pan-American Exposition. Thousands of Edison lamps will be supplemented by searchlights, both on land and on the fleets anchored in Hampton Roads, combining to make the nightly pageant magnificent and beautiful. ———————_>- The Peruvian Government, according to a Lima, Peru, cablegram, has contracted with United States capitalists represented by Alfred MacCune for the construction of a railroad to the River Ucayali, which is one of the two large confluents of the Amazon. The existing Peruvian railroad from Lima runs eastward to Oroya, about 125 miles. The subvention for the construction of the pro- posed road is said to be $10,000,000. April 18, 1907 The Wadsworth Portable Core Oven. It is the usual practice to bake foundry cores in brick ovens which occupy a relatively large space, and cannot be moved arrangement is required. economical and portable core oven is Several types of have been put on the market which are equipped with swinging doors. The objection to all ovens of this type is that there is a large amount of waste space, due to the difference between the area of the quadrant and the area of a square having sides equal to the radius of the quadrant. One objection to the quad rant or semi-circle type of oven is that it is not suitable for drying long cores such as are made in core machines, for the clearance which must be left along the curved edge of the shelf still further reduces the area that can be covered with core plates. The objection to all ovens of the stationary shelf type is that the core plates have when change in the general The desirability therefore of an more space or a efficient obvious. ovens (a Tar leon AGE Fig. 1.—Front View, Closed. The Wadsworth Core Oven Made by the Falls Rivet & Machine to be handled into and out of the oven through openings, which interfere with the heat or draft conditions and thus retard the baking of the cores in the oven. The accompanying illustrations show two views of a self-contained drawer oven which was designed by George H. Wadsworth, and is manufactured by the Falls Rivet & Machine Company, Cuyahoga Falls, Ohio. The one shown is equipped with four drawers, supported by rollers at the back and by pipe guides at the front. The drawers are removed from the oven by slipping a pair of handles into the pipes shown at the front, lifting them slightly and running them forward on the wheels on the inside at the back of the shelves, the action being much like that of a wheelbarrow. The shelves are self-sealing, in that when they are drawn forward a plate closes the opening, so that the baking of the cores on the other shelves goes on without interruption. Fig. 1 is a front view of the oven. In Fig. 2 the shelves are shown open and drawn to different distances, so as to illustrate the variety of cores which can be baked in the oven at one time. The large cores on the lower shelf are 7 in. in diameter.

The facility with which these different divisions can be put in will enable the operator to dry any size of cores read- ily. ee That the natural color of pure water is blue, instead of white, was long ago discovered. The green and yellow tints are said to be due to extraneous substances. Dis- solved calcium salts, though apparently giving a greenish tint, due to a fine invisible suspension, have no effect on the color of the water when precautions are taken to prevent it. The brown or yellow color due to iron salts is not seen when calcium is present. The green tint is often due to a condition of equilibrium between the color effect of the iron salts and the precipitating action of the calcium salts. The Pittsburgh Coal Company, Pittsburgh, will shortly let contracts for the building of 350 more coke ovens at its Grindstone plant in the Lower Connellsville region. It is now building 250 ovens at this plant, which will be known as Grindstone Works No. 1, while the additional plant of 350 ovens will be known as Grindstone Works No. 2. It is predicted that within a few years the Pitts- burgh Coal Company will be one of the largest coke pro- ducers in the country. 1188 A Feeding Device for Rolling Mills. Edwin E. Steel Slick, consulting engineer for the Carnegie Pittsburgh, rolling mill feeding device on a patent thas recently been is- Company, has designed a which sued. The invention is applicable to mills employed for reducing ingots, blooms, slabs, etc., to finished materials, and in which it is required to turn the piece from a flat to an edgewise position before entering the rolls for cer- tain passes. The plan in brief is to mount the housings for the pinch rolls and the guides in such a manner that they may from their horizontal move bodily receiving THE IRON AGE April 18, 1907 gear k. The shaft 7 also carries a bevel gear wheel, 0, Which meshes with a similar wheel on the shaft h, this in turn meshing with a third bevel gear wheel through Which motion is communicated to the lower pinch roll. The rock shaft h is actuated by means of hydraulic cy]- inders, r, through the links p, connecting to the arm s of the shaft. The slabbing and edging passes of the mill are shown at m and n respectively. The journal ¢ of the upper pinchroll is movable in guides of the housing d and the journal is connected by links v with the pivoted stop levers # adapted to engage a stop, w.

The arrangement of the gearing for actuating the pinch rolls is with a view to such movement of the rolls into the vertical posi- tion and also permits either movement to be reversed. When the pinch rolls and guides are lowered to the hori- vontal position to receive a new bar the lever @ engages the stop aw and raises the upper pinch roll in the guide of its housing d sufficiently to spread the two rolls to re- ceive another bar. As the pinch rolls are again lifted to April 18, 1907 the position shown in Fig. 2 the upper roll is closed to pinch the bar. The entry of the bar to these rolls is thus greatly facilitated and buckling of the steel is prevented. The device makes it possible to roll and edge material at the same time without changing rolls. It has been in- stalled at the Twenty-ninth Street or Lower Union Mills of the Carnegie Steel Company, Pittsburgh, and has worked quite satisfactorily. ee Mexican Railroad and Business Notes. DwuRANGO, April 10, 1907.—The Mexican Congress re- assembled on the evening of April 1. The address of Pres- ident Diaz to the Senators and Deputies was character- ized by the note of optimism which has become usual of late years, the only jarring chord in the paeon laudatory of financial prosperity and industrial progress vibrating upon the recent disputes between capital and labor, which resulted in riot and blood letting. The President re- iterates his determination to compel respect for the law. He notes with satisfaction the continued prosperity of the mining industry, and records the fact that in the periods from June to December of last year “ 2000 title deeds for mining properties were made out, embracing an area of 30,649 hectares.” Advancement in the mechanical arts and the expand- ing field for the utilization of the people’s energies have naturally given a stimulus -to inventive genius, a fact made evident by the increasing business of the Mexican -atent Office. In the first half of the current fiscal year 585 patents were granted and 475 trademarks and 44 commercial names and announcements were registered. The very general use of the waters of the country, both for the purpose of irrigation and for the generation of electrical power, is remarked in the message. Referring to progress in railroad building, the Presi- dent says: “Since September last the additions to the railroads subject to Federal jurisdiction have been a little more than 200 kilometers, and the present length of the system is 17,647 kilometers, which added to the 4259 kilometers of lines constructed under State conces- sions give a total of 21,906 kilometers.” Reference is also made to the recent acquisition by the Government of a controlling interest in the Mexican Central, the President expressing regret that “it has not yet been possible to arrive at a definite result in this affair, owing to the unsettled state of foreign markets and the necessity of studying carefully the legal form in which the arrangements will have to be carried out.” The financial position of the Government continues prosperous. Custom house collections have increased and “the currency situation has greatly improved.” The President notes the encouraging fact that “as against $43.000,000 of gold that had been coined on September 16 last, the coinage of gold has now reached almost $60,- 000,000 in pieces of 5 and 10 pesos.” Railroad : oncessions aud Construction. A good deal of local enthusiasm was aroused at the Pacific port of Mazatlan a few days ago by the beginning of work upon the Southern Pacific Railway Company’s extension from that point north to the port of Gudymas, Sonora, and south to the city of Guadalajara, in the State of Jalisco. Elaborate ceremonies marked the in- auguration of actual construction work. Operations will also shortly be commenced at the last named point, and the entire line will, it is expected, be completed in three years’ time. Much material is being received at Manzanillo for the Mexican Central's extension now in course of con- struction. Track laying is in progress south of Tuxpan. Richard Honey, a gentleman well known in Mexico in many lines of industrial activity, is reported as having commenced work on a new railroad which is to be known as the Pachuca, Zimapan & Tampico. Mr. Honey holds a concession from the Federal Government and also from the State government of Hidalgo, the latter carrying a subsidy. A portion of the line has already been located. The proposed route is from the mining camp of Pachuca, which is also the capital of Hidalgo, through the mining territory of Actopan, Cardonal, Bonanza and Zimapan, THE IRON 11&9 AGE and from that point through to the Gulf coast at Tampico. Good progress is reported upon the construction of the Cananea, Yaqui River & Pacific, a branch line of the Southern Pacific Railway Company. It is estimated that 400 kilometers will be laid by the end of the year. The State government of Chihuahua has given a concession to John L. Johnson for the construction of a standard gauge line from Cerro de los Lamentos to the station of Ojo Caliente, cn the Mexican Central, a year being al lowed for the completion of the work. Industrial Notes, A concern named Compania Nacional Explotadora de Carbon y Coke, capitalized at $1,000,000, has been or- ganized in the City of Mexico to develop certain coal bodies on the San Blas hacienda in the State of Coahuila. The officers of the company are: Fernando Pimentel y Fagoaga, president; Gustavo Block, Jacinto Pimentel, Angel Lopez Negrete, Arturo Braniff, Javier Icaza y Landa, Luis Barroso Arias, J. Silecido y Aviles, F. Asun- solo and Diego Redo. An extensive system of irrigation, involving the con- struction of reservoirs and distributing ditches, is to be undertaken by certain land owners near Taso del Zacate, in the State of Nuevo Leon. Senor Isaac Garza is inter- ested in the enterprise, and may be in the market for pumps and piping. An item appeared in the local press a few days ago to the effect that “one of the largest shipments of steel yet received in Mexico” was in course of transit from Vera Cruz to the City of Mexico. It comprised 29 cars of structural material to be used in building a new public edifice. J. J. D. ———_-@e______ A New Engineering Building at Swarthmore. The new engineering shop building, at Swarthmore College, Swarthmore, Pa., is completed and ready for use. The building is three stories in hight. The archi- tectural design is simple and effective, and harmonizes well with the building adjacent to it. The walls are con- structed of hollow concrete blocks, and the second and third floors are of reinforced concrete carried on concrete beams and columns designed to carry a live load of 150 Ib. to the square foot. The stairs and landings through- out are of reinforced concrete with metal railings and guards. On the first floor there are two testing rooms, vault for records, a locker and 3300 sq. ft. of space which will be occupied by the forge and foundry. The second floor will be used for iron and machine shops, besides several rooms for offices and two lecture rooms. The third floor will be equipped for pattern mak- ing and woodworking. The building is covered with a slag roof, and with the exception of this roof it will be entirely fireproof. The heating will be steam radiation, operated by the Webster vacuum system, and the lighting will be done entirely with electric lamps and reflecting ares. The ele- vator and machinery in the various shops will be op- erated only with electric motors: and long lines of coun- tershafting will be avoided by grouping the machinery on separate motor drives. ——__-- ——————___ At the annual election held by the new Board of Directors of the Cleveland, Ohio, Chamber of Commerce. held on April 11, Lyman H.

The latest addition to the line of spiral disk grinders manufactured by Charles H. Besly & Co., Chicago, IIL, is the No. 14 herewith illustrated. It is regularly equipped with 20-in. disks, but as a maximum will swing 23 In general it is very solidly built to satisfactorily size 23 in. handle the severest work of this character which it might be called upon to perform. There are certain improvements and changes in this machine from those formerly manufactured. The gen- eral appearance is somewhat different, the design of the frame being slightly changed; but what is more impor tant, the table guilding and controlling features have been improved. Both tables are made to rock in front of the grinding wheels, and are adjustably counter- weighted to retain normally a vertical position. Hereto- fore the left hand table has been made to clamp only. It is now provided equipped with a detachable bevel gauge graduated to 45 degrees. The right hand table has in addition to the rocking motion about the horizontal THE IRON AGE April 18, 1907 contact with the work is corrugated in such a manner as to have an effect in grinding that corresponds to a shearing cut. The end thrust of the spindle is taken on large hardened and ground steel collars, situated between the driving pulley and the flanges of the bronze bushings in .e spindle bearings. The machine occupies a floor space of about 5 x 10 ft., and weighs in the neighborhood of 3000 lb. The right hand lever feed table has a top area 10 x 12 in. Both tables have vertical adjustment and a rocking motion, and are dustproof. When desired either table may be clamped to the rocker shaft and used as a stationary table. ee Railroad Shortcomings in Germany. To American manufacturers the following from a German trade journal has a strangely familiar sound, and it looks as though state control does not lead to much better results than the despised thandling of busi- ness by railroad magnates: “In consequence of the heavy pressure upon the iron The New No. 14 Spiral Disk Grinder Built by Charles H. Axis a tilting adjustment in a vertical plane, so that the faces of parts to be ground may be finished at other than right angles with the surface upon which they rest. The right hand table is provided with slots and a keyway for attaching angle plates or other work holders. It is ar- ranged to feed perpendicularly to the wheel by the ma- nipulation of the hand lever shown. There is also a micrometer stop screw on this table, graduated to read to one-thousandths of an inch, which makes it possible to grind a definite amount from the surface of the work. The design of the machine as a whole shows the prin- cipal consideration to have been a large producing ‘ca- pacity, and to that end the handling of work in duplicate has been made as easy and rapid as possible. The table is mounted on a gibbed dovetailed slide, and is movable to and from the grinding disk by a lever, pinion and rack, giving a leverage of 14to1. Through this mechanism, with comparatively little exertion, the operator may exert a pressure of the work against the abrading disk that realizes the maximum efficiency in the grinding, making it possible to accomplish a large amount of work in a given time.

At times the orders and specifications of the home roads were so heavy that the German car shops and locomotive works were forced to strain their resources in order to keep to the short deliveries demanded by an unprecedented scarcity of cars and locomotives. Even now the shops are supplied with orders for a long time. But whether the rolling stock -ordered will suffice is doubtful. The following is a startling fact: On account of scarcity of cars the production of coal declined by 2,000,000 tons during this winter. This means a falling off in business to the collieries of 20,000,000 marks and to the miners a loss of wages of from 5,000,000 to 6,000,000 marks. The principal blame for these saddening conditions lies with the Government railroad management.” — — + It is stated that the Hopewell iron ore mines in Ches- ter County, Pennsylvania, which have been idle for about 20 years, have been leased by a syndicate headed by Henry D. Saylor of Pottstown, Pa., and that the tract of 168 acres will be developed. A large amount of ore is said to be in sight. April 18, 1907 The Pennsylvania’s All-Steel Mail Car. The nearest approach to a truly all-steel railroad car is mail car No. 6546, recently built to operate on the Penn sylvania lines. With the exception of 370 Ib. of wood, 2840 lb. of fireproof composite and asbestos board, 3200 Mail Car. Interior of the All-Steel Fig. 2. lb. of cement flooring and a very small amount of rubber, everything is metal, including paper cases, letter cases, paper boxes and doors. This car, shown in Fig. 1, is 19 ft. longer than postal cars built heretofore, and has an entirely new interior arrangement, which may be seen in Fig. 2. It includes storage space at each end of the ‘ar, eliminating the necessity for turning the car end for end at terminals. The maximum outside dimensions are 74 ft. 9% in. length over buffers, 9 ft. 11% in. width over roof eaves and 14 ft. 5 in. hight from top of rail to top of junction box on roof. The inside length is 70 ft. 8% in. and inside width 9 ft. 5¢ in. THE IRON The New All-Ste AGE I1QI The strongest and best equipped car heretofore was that known as the “ Universal Postal Car,” which has an inside length of 60 ft., is of wood construction, with re- inforced ends containing 10-in. I-beams placed vertically at each side of the doorways; is lighted with Pintsch gas lamps and weighs 110,000 lb. The 70-ft. steel car has THe RON AGE el Mail Car*No. 6546 12-in. I-beams placed vertically at each side of the door- ways, is lighted by electric lamps, in conjunction with storage batteries and an axle light generator, and weighs 128,500 Ib. The trucks and body framing incorporate all the fea- tures which were found satisfactory in the steel passenger ear. The trucks are of the six-wheel type, having a framing entirely of steel, and are of sufficient strength for use under cars having a total loaded weight of 190,000 Ib. <A special flexible spring rigging, combined with the use of four side bearings per truck, imparts exceptionally easy riding qualities to this truck. The axles are of large diameter, and the wheels are made of rolled steel. The body framing includes a heavy central box girder, built up of two 18-in. I-beams and two % x 24 in. cover plates, and side girders 36 in. deep, having a strong bottom flange of large area, which also forms the belt rail. A 12-in. I-beam is placed on each side of each end door, riveted at the bottom to a steel center sill end cast- ing and at the top to a cross beam of channel section. The cross beam distributes to the roof construction and side plates the strains, which may come on the vertical I-beams in time of collision. This strong end framing, combined with the peculiarly heavy longitudinal girders in the underframe, offers greater resistance to end shock than ever before attempted. ; The flooring consists of a cement, which is spread over corrugated iron foundation plates in a plastic state. The outside sheathing, including the roof, is made of steel plate. The inside of the car, where not covered with furniture peculiar to postal cars, is lined with fireproof composite board. All inside lining plates are covered with an asbestos cloth glued to the sheets, to reduce the sound and heat conducting properties. The wires and storage battery boxes for the electric lighting have been carefully insulated. The steam heat and brake arrange- ments are of the latest and most improved types, and the draft gear is of the same flexible, strong pattern which has given excellent service on the steel passenger car. The furniture in the car is in conformity with the requirements of the Railway Mail Service Department, but is made of steel instead of wood. The only danger from fire will come from the inflammable nature of the mails, and fire extinguishers are provided to guard against that. 1192 THE New National Portable and Stationary Air Compressors. The increasing use of compressed air in manufactur- ing and power plants, car barns, &¢., has given quite an impetus to the manufacture of electrically driven air which and conveniently taken to the place where the compressed air is utilized. In drilling, riveting and chipping compressed air tools can be more advantageously employed than purely manual or mechanically operated devices. In railroad car barns or at steam railroad terminals compressed air is convenient and effectual in cleaning out dirt and dust. In power houses and substations it offers many advan- compressors are self-contained electric IRON AGE April 18, 1907 29% in. wide over all, which permits it to be taken read- ily through doors and narrow or crowded spaces in shops and factories. One of the distinctive features in the air compressor furnished with the portable outfit is the con- struction of the motor and compressor as entirely sepa- rate and self-contained units. When the two parts are assembled a compact and rigid unit is produced. The crank chamber cover and the motor base are separated by a in, air space, which acts as an insulator of the heat radiated by the compressor and decreases the tendency to heat the motor. i bracing and This separate cover gives the required stiffening for the crank chamber casting. The accessibility ef all parts likely to need attention is illustrated in Fig. 2. The crank shaft is fitted with a third bearing in the Fig. 1. Motor Fig. 2.—The tages in blowing out dust from genergtor coils, field mag- neis and commutators. In automobile garages it is espe- cially useful fer inflating tires, cleaning dust from cush- ions, running gear, &¢. The simplicity, flexibility, cleanli- ness and reliability of air as a source of power for a great many different purposes is coming to be better recognized. A demand exists for a self-contained and stoutly constructed portable compressor outfit, which the National Brake & Electric Company, Milwaukee, Wis., has sought to supply in the type illustrated in Fig. 1. The outfit comprises a compressor, an automatic type H and compact, governor and necessary piping, an air gauge reser- voirs, and a combined switch and fuse, the whole being mounted on a substantial angle iron frame supported on wheels. The front wheel is hung in a pivoted fork made of cast steel, the outfit being drawn around by a wrought iron tongue. One of the greatest advantages in the new design of the National portable air compressor is the exceptionally small width of the outfit, the parts without waste of space on the truck. which is gained by disposing It is only and Compressor Partly Unassembled. Portable Motor Driven Air Compressor Built by the National Brake & Electric Company, Milwaukee, Wis center, to support and strengthen it at this otherwise weak point. All bearing and working parts of the com- pressor are lubricated by the splash system of oiling. The gear and crank are inclosed in a bath of oil, which is splashed over all the operating parts of the com- pressor, The valve head is constructed with the discharge valve toward the center and the suction valve toward the outside of the head. The discharge pipe runs straight out. from th. valve head to the main reser- voir, thus dispensing with the necessity of attaching elbows. The suction has two openings, one on each side of the valve head; either or both can be used. A standard National four-pole inclosed motor is used, the frame of which is cast steel in two parts, forming a box shaped covering for the armature and field coils. The pole pieces are integral with the frame. The standard type N oil pneumatic governor, with cover removed, is shown in Fig. 3. The governor is extremely simple in design, has few working parts and oc- cupies very little space. The essential features of the device are a cylinder 1% in. in diameter, which is con- nected direct to the main reservoir; a piston working in the cylinder is acted upon on one side by the pressure of the air in the main and on the other by the expansion of the operating spring. Movement of the piston throws a toggle joint over its center and causes a hammer to strike a switch arm, which makes or breaks the circuit to the air pump. The working parts are all contained in a box filled with oil, which not only serves to keep the working parts lubricated, but also extin guishes the arc caused by breaking the circuit. <A tightly reservoir fitting cover prevents leakage of oil. With the portable outfit there: is safety va.ve, an air gauge, piping and a hose container large enough to hold from 75 to 100 ft. of hose. Type L Water Jacketed Stationary Compressors. These compressors are identical in every respect with also furnished a the compressors just described, except that provision is made for a circulation of water around the cylinders and heads, keeping these parts at a minimum temperature April 18, 1907 and permitting the machines to be operated continuously. All working parts of the compressor operate in a bath of oil, The other parts are automatically continuously and thoroughly lubricated. With the water jacketed types there is furnished a water governor which automatically cuts off the circula tion of water as soon as the compressor is shut down, and admits it to and when the is started up. Although the working parts of the machine are entirely inclosed and protected from in- jury, accessibility was carefully considered in the design and every part can be quickly and easily inspected. the cylinders heads com pressor The Governor with Cover Removed.

The portable compressor outfits are made in capacities of from 11 to 50 cu. ft. of free air per minute, and the water jacketed types from 12 to 35 cu. ft. of free air per minute. ———_—_ +e __ ——— San Francisco Trade Topics. San Francisco, April 8, 1907.—Largely on account of the weather business for the greater part of the month of March was quiet and sales in all lines of merchandise fell off. It was practically impossible most of the time to transport goods through San Francisco streets on account of the mud, so that supplies of lum- ber and hardware could only with difficulty be brought to the buildings in course of erection, and where these buildings were not closed in no work could be carried on at all. Of course this inconvenience has been only tem- porary, but it has been felt by the retailers. Indeed from the first of the year the weather has been so rainy that it has interfered with business in every line, and although owing to the peculiar circumstances of the city it cannot be said that less goods have been sold than for the same time in 1906, still there has been a falling off in demand causing much disappointment to the trade. Of course all the supplies that would have been bought will be needed later and the total for the year may not fall behind that of 1906—indeed, it promises to exceed it considerably. Great activity has set in during the past three or four days in the building trade, and retail sales of hardware have started up again with great briskness. Crops of all kinds promise well. There will be a good crop of barley, a medium one of wheat and the fruit crop will be large. The lumber business will exceed all precedent. The oil fields will show a large increase of production. Copper will also do well. The produce of California in 1907 will sell for a big price, and there will be a prosperous year in every line of business. In common with many other lines the iron and steel trade will suffer at least temporary the withdrawal of the vessels of the Oceanic Steamship Compan
