A gang of men will follow with the lining of the tunnel, which is cast iron. The tunnel will thus be completed as the work progresses. A blowing en- gine will force air into the tunnel through a 24-inch pipe. A force of 125 men will be employed on each side of the river night and day. The Collector at Port Huron reports that it will take about three months to put the plates together in the required form. The finished tunnel will comprise 2500 feet on the American side, 2200 under the river and 3000 on the Canadian side. It is estimated that the work will cost $2,500,000, although well- informed men predict that it will cost nearer $5,000,000. President Sir Henry Tyler and Manager Hickson have been heard to remark that it will be completed if it costs $10.000.000.

According to reports of English news- papers, the new steamer City of Paris, which recently made her first trip across the Atlantic, bids fair to rival in speed the present ocean greyhounds. When steaming toward the Alfred Dock, Birkenhead, she performed the remarkable feat of turning almost around in her own length, increasing the interest of the spectators who were watching her. The new vessel is a fac-simile of the City of New York, but is expected, in regard to her steaming quali- ties, to far distance her prototype. Ac- cording to the present plans, she will first be submitted to a thorough and practical test of one or more voyages to New York in order to insure easy working of her machinery. The reports state that on the trial trip, when the water was a trifle rough and the wind strong, the ship was driven at 15 knots, then at 18, then at 20, the engines all the time working with complete satisfaction. The final trip was an extended run, during which 21.59 knots an hour were registered. During the run from Greenock to Liverpool, with strong head winds and through a choppy sea, the ship made 20 knots an hour, this rate being continued the greater part of the night. Although the City of New York and City of Paris are sister ships, laid down at the same time and built from the same designs, the latter has occupied six months longer in construction, The building of thereby greatly the City of New York was pushed forward | to meet the press of traffic; but the City of Paris has been carefully and elaborately finished, and her engines have received the most minute attention, and the result is that, although new, the machinery has worked without the slightest hitch. Two years were occupied in the Except that in the newer ship the Company have discarded some of the patent apparatus which in the City of New York | worked unsatisfactory, the two vessels are in every detail identical. Like the City of New York, this latest addition to the Inman line is 565 feet long over all, 63} feet broad, 42 feet deep, and 10,500 tons gross regis- ter. Her engines are capable of develop- ing 20,000 horse-power. She has five decks, and the depth of the hold is 394 feet. Accommodation is provided for 2000 passengers—700 first-class, 390 second- class, and the remaining 910 steerage. regards her decorations and appointments, the vessel is literally a floating palace, re- plete not only with every comfort, luxury. She has a promenade deck ex- tending from stem to stern. Below, the saloon dining-room is capable of accommo- dating 300 passengers; it is the width of the ship, and has an arched roof 20 feet high, with alcoves along the sides. At the after end of this spacious saloon there | is a large hall, in which is placed a grand staircase leading down to the luxurious drawing-room and library. reom, another elaborately fitted apartment, is on the upper deck. It is 45 feet long and 27 feet broad, and will hold 130 votaries of the weed. It is a feature of the City of Paris, as of her sister ;ship, that there are provided for saloon passen- gers a number of elegantly appointed private sitting-rooms, as well as private bathrooms. Altogether the state-rooms for first-class passengers number about 480. For the second-class passengers there have been provided a tastefully decorated and elegant dining hall, 40 feet wide, 27 | feet high, and capable of holding 150 diners. There are also 96 second-class state-rooms. The ship is divided into water-tight compartments, without doors, and would be perfectly seaworthy with three of these divisions flooded.

Ford, chemist of the Edgar Thomson Steel Works, at Braddock, Pa., recently contributed the esting article to the Greensburg Press, which we reproduce: So much has been claimed for natural | regards the superiority of | its heating properties as compared with that following inter- | (Pa.) gas as coal some analyses of this gas, together with calculations showing the | gases we find that 100 liters current | comparison between its heating and that of coal, may be of to your readers. These calculations are, of course, theoretical in both cases, and it | must not be imagined that the total amount of heat in a ton of coal or in 1000 cubic feet of natural gas can ever be | fully utilized, In making these calcula- tions I employed as a basis what in my estimation was a gas of an average chemi- cal composition, as I have found that | from the same well varies continually in its composition. Thus, samples of gas from the same well, but taken on different days, vary in nitrogen from 23 per cent. to nil, carbonic acid from 2 percent. to nil, oxy- gen from 4 per cent. to 0.4 per cent., and | so with all the component gases. Before giving the theoretical heating power of 1000 cubic feet of this gas I will note a few analyses. The first four are of gas from the same well, samples taken on the same day that they were analyzed. The last is from another well in the East | Liberty district.

We will now see how the natural gas compares with coal, weight for weight, or, in other words, how many cubic feet of gas will contain as many heat units as a given weight of coal—say aton.

Now, 1000 cubic feet of this gas will weigh 265,887 grains, or, in round numbers, 38 pounds avoirdupois. We find that 64.8585 grams, of carbon contains 52.4046 heat units and 265,887 grains, or 38 pounds, of carbon contains 139,398,896 Then 57.25 pounds of carbon will contain the same number of beat units as the 1000 cubic feet of the natural gas— viz., 210,069,604. Now, if we say that coke contains in round numbers 90 ~ cent. carbon, then we will have 62.97 pounds of coke equal in heat units to 1000 cubic feet of natural gas. Then if a ton of coke, or 2000 pounds, costs $2.50, 62.97 pounds will cost 7,5, cents, or 1000 cable feet of gas is worth 7,5, cents for its heat- ing power. We will now compare the heating power of this gas with coal, taking as a basis a coal slightly above the general average of the Pittsburgh coal—viz. : NG os Kv escnid Gamaecs x2. 75 PRs sad aha (oR ea Rese. 52 RES 1 Ey chia br dw ataer wane 1.04 a...

If our coal costs us $1.20 per ton of 2000 pounds, then 54.4 pounds costs 3} cents, and 1000 cubic feet of gas is worth for its heat units 3} cents. As the price of coal increases or decreases the value of the gas will naturally vary in like propertions, Thus, with the price of coal at $2.50 per ton, this gas will be worth 6,5, cents per 1000 cubic feet. If 54.4 pounds of coal is equal to 1000 cubic feet of gas, then 1 ton of coal is equal to 36,764 cubic feet. In these calculations of the heating power of gas and coal no account is, of course, taken of the loss of heat by radiation, &c. My object has been to compare these two fuels merely as re- gards their actual value in heat units. in collecting samples of this gas I have noted some very interesting deposits from the wells. Thus, in one well the pipe was nearly filled up with a soft grayish-white material, which proved on testing to be chloride of calcium. In another well, soon after the gas vein had been struck, crystals of carbonate of ammonia were thrown out, and upon testing the gas I found a con- siderable amount of that alkali, and with this well no chloride of calcium was ob- served until about two months after the gas had been struck.

The two platens are arranged one above the other, the lower moving up and down and the upper swinging backward and forward; when the latter is brought forward over the other the mold on the lower is forced up against the upper platen to compress the sand, and then as the lower platen drops the upper is thrown backward for the re- moval of the prepared mold and the prep- aration for another. The lower platen is supported upon two vertical slides working through guides in the bars of the frame. Placed in bearings in the lower part of the frame is a rock shaft having a backwardly projecting arm, upon which rests a strut bearing against the under side of the lower platen, so that when the shaft is turned it HAND OR POWER MOLDING will raise or lower the platen. The shaft is operated to produce the eompressing movement by means of an elastic lever. The upper platen is carried by two rods hung on trunnions at their lower ends. In operation the flask and sand with the | mold are placed upon the lower platen, when the upper platen is drawn forward | and the lever moved to raise the lower platen and compress the sand in the mold. Power is applied to the machine by a cam working against the back of the spring lever and mounted upon a shaft to which | The construction is | power is transmitted. such that the rock or cam shaft only rises to produce compression when the upper platen is in its forward position over the lewer; a single revolution of the shaft | then produces the compression, when power is automatically detached.

This machine is made by Reynolds & Co., of New Haven, Conn., who also manufacture other forms of molding ma- chines which have been long and favorably known, em The grand ship canal between Liverpool and Manchester is being made with won- derful rapidity.

Natural Gas. = ~ - Si oe al cae A recent circular, relating to a proposed new mortgage loan of $2,500,000 of the ‘* Philadelphia Company,” Geo. Westing- house, president, and Chas. Paine, vice- president and general manager, who practically control the natural gas supply in and around Pittsburgh, gives a succinct statement of the past and present of this great product: Organization.—The Philadelphia Com- pany were reorganized May 24, 1884, under the provisions of a special charter, origi- nally granted to the Empire Contract Com- MACHINE, MADE BY REYNOLDS & CO. pany by an act approved March 20, 1871. The rights, powers, privileges and fran- chises conferred by and in said act of in- | corporation are exceptional in their nature and value, and are enjoyed by no other natural gas company. | Business.—Notwithstanding the liberal scope of its charter, the business of the | company is at present confined to the min- ing, conveyance and sale of natural gas. | Although the existence of this wonderful product has been known for centuries, and its utilization attempted in a small way ages ago, the year 1875 marked its first in- troduction in the manufacture of iron, and not until the product of the famous Mur- irysville Well was piped to Pittsburgh in 1883 did the people of Western Pennsy] | vania realize its value and recognize in it the fuel of the future. The Past and Present.—Entering the |field in 1884, the Philadelphia Company | found it already occupied; but, equipped | by the inventive genius of their promoter, Mr. Geo. Westinghouse, Jr., with many | appliances for the safe conveyance of gas, and backed by a capital of $5,000,000, ——— increased to Philadelphia Company soon distanced their competitors. So great*was the advantages gained by an unfailing supply of gas, su- perior facilities for delivering the same, 7,500,000, the! | dent, that finally most of the competing | companies sought and obtained the _privi- lege of incorporation with the Philadel- phia Company, or placed their lines in their | hanfls for operation under lease. Thus | the company practically control the gas Lsipply of the cities of Pittsburgh and Alle- gheny and their suburban villages; also 13 surrounding towns and boroughs. Ref- | erence to the accompanying map (not en- | egraved) will show the extent of the com- pany’s mains and their favorable location. Originating in the three greatest anticlinal reservoirs yet discovered—Murrysville, Grapeville and Canonsburg—they carry the product of 200 producing wells to Pittsburgh by 19 different routes, supply- ing on the way the towns and villages men- tioned. By a comparatively small ex- penditure the adjacent fields of Bakers- town and Belle Vernon, where the com- | pany have large tracts of promising gas ter- | ritory in reserve, can be made tributary te | the company’s supply. The Low- Pressure Syste m.—The cities of Pittsburgh and Allegheny are supplied with gas at low pressure through a system of mains and service lines aggregating 258 miles in length, of which 206 miles, owned in fee by the company, cost considerably more than $2,500,000. This portion of the company’s work is practically completed, | nearly every street of any consequence having already been piped. The principal mains are of unusual size, being from 20 to 36 inches in diameter. All city lines have been constructed in the most approved and substantial manner, with double joints, escape-pipe, and other patent appliances, which, with automatic regulators and cut- offs, reduce the chances of accident to a minimum. | | | The company’s plant now is: Miles. | Pipe lines owned in fee.. ... 524.18 | Pipe lines operated under lez 185,29 | ——. 79.47 Acres. | Gas lands owned in fee....... ones 381 | Gas and oil rightsin fee..... «xee ae | Gas and oil leases.......... vo cae | —- 7,126 Gas and oil rights and leases of leased companies................ 16,77 | Total gas territory controlled by Philadelphia we .. 33,899 | Number of producing wells...... 200 Miles. | Telephone lines owned in fee..... 121.75 | Telephone lines leased............ 65.50 — 187.25 | Consumers.—On January 1, 1889, the | Philadelphia Company were supplying 750 | manufacturing establishments, including | 38 iron and steel works, &c., and 23,080 | houses.

The motive power is furnished by a 74 horse-power Thomson-Houston motor, 1, securely fastened to the draw by iron braces. On the end of the armature shaft, which revolves at the rate of 1500 turns a minute, is a pinion 4} inches in diameter engaging with a gear 15 inches in diameter. The shaft of this gear carries a beveled pinion 5 inches in diameter engaging with one 15 inches in diameter mounted on a vertical shaft. Power is then trans- mitted through a train the five pinions of which are 7 inches in diameter and the five gears 14 inches in diameter, the faces of all being 4 inches. On the bottom of the last or slowest revolving shaft 3 is an 11- inch pinion, 4, which engages with the ELECTRIC MOTOR. The recon- | but this method was found to be open to | circular rack, 5.

One of the most remarkable aggrega- tions of automatic machinery is assembled under the roof of Norton Brothers’ can factory at Maywood, near Chicago. In the character of the work performed and the results accomplished it is claimed to be superior to anything else in the line of automatic machinery. Norton Brothers are manufacturers of tin cans of every de- scription. They have manufactori°s at Fig. 2. CONNECTIONS OF BRIDGEPORT DRAWBRIDGE. DIAGRAM SHOWING ELECTRICAL 000. Already there are two bridges, at Montreal and Lachine, which unite the Colonial system with the Western lines, and a bridge in progress at Coteau will give a third connection for an all-Canadian route between the Atlantic and Pacific. The coal barge lines in the New York and Eastern trade are increasing their fleets by adding several vessels of the largest capacity adapted to the outside route. At Norwalk, Conn., six barges of about 1300 tons each are building for the New London Outside Towing Line, which is en- gaged principally in the bituminous trade with Virginia. The Boston Towboat Com- pany is enlarging its scale ef operations by | building a large number of 2000-ton barges, regular sea-going vessels, previded with sufficient sails to be navigable even though the steam escort should be com- pelled to cut loese.

They own the special machines used in all these factories, which are the invention of Edwin Norton, whose genius in devising and perfecting automatic ma- |chinery places him in the foremost rank of those American inventors who have aston- ished the world with their achievements. The consumption of tin plate in these works is enormous, far exceeding that of |any other works in any branch of manu- 'facture in the world. A recent visit to | their works at Maywood was full of in- terest. Upon entering the factory, the first de- Recently they purchased the| | is the machine-shop, in which all the ma- | chines and tools used by the firm are built. ‘It contains an excellent equipment of | planers, lathes, drills, &c. A novel feat- /ure about it is the tool-room, which is kept }on an original plan which is worthy of | general adoption. This room is connected by an electric system, similar to that used in hotels, with every part of the machine- shop and other portions of the factory in | which tools are likely to be called for by |the workmen. A hotel annunciator hangs in a conspicueus part of the tool-room. When a workman wants a tool he pushes a button near him and immediately a ‘*bell-boy ” runs to him from the tool- room with a slate and pencil, on which he writes his name and the tool desired. The |numbers on the annunciator correspond with the numbers of the buttons, te fix the location of the summons. The boy hands the slate to the tool-room keeper, who has a list of the workmen’s names, | numbered according to the order in which they are placed on the list, but without reference to the number on the annunci- ator, which is an independent matter. A rack hangs conveniently near with a suf- ficient number of pins on it to hold small brass checks numbered to correspond with the workmen’s numbers. Each pin holds a stock of several checks of the same num- ber. The toolroom-keeper takes one of the checks of the man who sent for a tool, puts it in the toel-rack from which he takes the article wanted, charges the workman with it in a book kept for the purpose, and sends the boy back with the |tool. The time of the workmen is thus saved, there is no confusion in the shop from men loitering to talk with others on their way to and from the teol-room, and a perfect record of the tools is always kept. When the tool is to be returned the boy is }again called, the workman is credited | with it on the books, and the check is re- stered to its place on the rack. This is }an instance of the methods employed throughout the whole factory, care being | taken in every respect to have operations cenducted systematically, economically | and with the least friction. Entering the can-making department, a long row of machines is seen, which stretch with their connections from one side of the large uilding almost to the other. In these 1 achines the tin plate is fed, cut into pie es of the proper size for can-bodies. It is drawn ito tubular form over a mandrel, double seamed, and passed on into a carrier. The subsequent operations of heading, soldering, testing for leaks, drying, counting, and delivering either into the warehouse or the car for shipment proceed steadily onward without the inter- vention of a hand to direct any of the movements of the machinery orto perform any part of the manufacture. The disks for the heads are cut on a number of presses, with the dies so arranged as to cut out the greatest possible number from a sheet of tin plate. The dies are arranged in gangs, and cut out alternate disks at one oper- ation and the intermediate disks at another, | as their frame-work would not permit them |to be set close enough to cut all out at ‘once. From the largest spaces of tin plate | left between the holes thus made a set of | gang-dies cuts out can tops, and from the remnant still existing another set of gang- dies cuts out small disks for button covers to be sold to button manufacturers. Use has thus been made of the tin plate as far | as possible in these works and the residue | is sold for scrap to sash-weight manufact- | urers. The caps for cans are already prepared | with solder for the soldering iron when | they are shipped to the canning factories. This solder is cut out of sheet solderin the form of a ring of the proper size and it is |forced on the rim of the cap. It was |found necessary to devise a special ma- will during the season add four ocean | partment into which the visitor is ushered | chine to do this in order to use the solder- : —" : gE SONY Be ee ante el mews) € det) Mb ae B/S ws a i a ee ™ SR) iP.

The solder being in place, it is easily fused and is in just the proper quantity. The edge of solder on the cap also preserves it from rusting if the caps and cans are carried over from one season to another, and thus avoids what might be, and often has been, a serious loss. The manufacture of sheet solder is carried on in this factory by an original method, which is in itself a revolution in metallurgical methods, and will be more fully described in an addi- tional article. It is sufficient to say here that Edwin Norton has solved the problem of rolling molten metal directly into | sheets, which has so long batiled the lead- ing metallurgists of the world, from Sir Henry Bessemer down. For months in | one corner of this factory a machine has been in successful operation, producing from molten solder beautifully rolled sheets from 6 to 8 inches wide, ;}5, inch thick, at the rate of 400 feet per minute. A very large stock of tin plate is carried, and a special storehouse has been con- | structed for it, with every facility for making it a bonded warehouse in case the duty should be advanced as contemplated, when a much heavier quantity would at once be laid in,to be drawn upon as needed afterward. An addition is just being built to this factory, which is 208 feet long by 137 feet wide, to be used tor storage. This build- ing is constructed of wood, with sheet- | steel roofing and siding, to make it fire- | proof externally. It is intended to hold | 25,000,000 cans. It extends for its full length along the Chicago and North- western Railroad tracks, with doors placed at regular intervals of a car length apart, so that a number of cars can be loaded at the same time. In connection with the other buildings of the factory there is a frontage of 600 feet on the railroad, with doors arranged in this way for the whole distance. An elevated railroad runs from the car department through a covered passage to the new warehouse, and the cans roll along it by gravity to their destination, which is controlled by suit- able switches, traveling over 1000 feet from their starting point. With such facilities it is not strange that a car can be loaded in an hour and a half and that over 100,000,000 cans can be shipped in a season from these works. ome I Railroads in Europe.

TT —— Steam-Jet Chimney Draft Improver. al This machine is applicable whenever m-_ sufficient draft exists in chimneys which are too small for the purpose, or when the adjacent buildings are so high as to destroy the natural draft. It is constructed in ac- cordance with the principle of the induced current, and while not decreasing the area, will create sufficient draft under all circum- | stances. The machine is composed of nozzles of gradually increasing area placed concentrically one above another. Enter- ing the lowest and smallest nozzle is a| steam-pipe leading from the boiler. The | supply of steam is controlled by a valve | RS] SY ROMO DSO RS SOO By SS s SSS | SS SS SSS BS RSS AX WAVY Shae) Sad SESS DSSS PSE MM ARVHVQ AW ESS ES DOSVAVRN AAV SS BS SE DAA i Steam Jet Chimney Draft-lmprover. located near the outside of the chimney. A slight opening of this valve is sufficient to induce a current of air through the side openings of the nozzles, which, multiply- ing as it ascends, produces a powerful suction at the base of the chimney, with | very small consumption of steam.
