Co., of Chicago, IIl., are the manufacturers of the automatic hoisting engine illustrated in the accom- | panyine engraving, and which is specially designed for blast-furnace work. The first one built for the furnace of the Cieveland Rolling Mill Co, has now been in operation for nearly two years, during which time, we are informed, it has given entire satisfaction. A prominent feature of the engine consists in the fact that it is operated and controlled entirely by those at the top of the hoist, thus dispensing with the engineer usually re- quired at the trottle of all large engines. Inspection alone will show that the different parts of the engine are strong and well | proportioned, considering which, as well as the care with which the different portions have been put together, the manufacturers state that they do not hesitate in recom- mending it for double duty—for instance, where blast furnace stacks are close together. The hoist shown in the cut has an ample capacity for hoisting material necessary for an output of 400 tons per day. The cylin- ders are 14 by 18 inches, with a speed of 500 feet per minute, and the proportions of gear | and pinion with the drum are made to suit | the load and speed desired. The drum, moreover, can be arranged for any length of hoist. The manufacture of blast furnace hoisting engines has been a specialty of the | company for almost 15 years, and they claim that one-sixth of all the furnaces in the country have adopted their engines, this un- doubtedly being a sufficient guarantee of their merits. A special circular of blast- furnace engines, as well as other hoisting and coal-mining engines, giving the various sizes and duties, has been issued by the company and will be mailed on application a Cranes—A Study of Types and Details.* BY HENRY R. TOWNE, STAMFORD, CONN. -(Concluded.) TRAVERSE GEAR In this, as in the hoisting gear, good de sign and construction are essential to econ omy of power, and frequently to safety against accidents. In some types of rotary cranes no traverse mechanism exists, except an arrangement of parts which provides for the rotation of the crane. In others, such as jib and derrick cranes, provision must also be made for moving the truck or trolley horizontally on the jib, and the same pro- vision is required for moving the trolley of bridge and traveling cranes transversely on the bridge. In all such cases a separate mechanism, distinct from the hoisting gear, has heretofore been employed, and is suill sometimes desirable or con- venient. When employed, its parts should be as few and simple as possible, and it should be so far independ- ent of the hoisting gear as to permit either to be used at =— any time separately or con- ~~ jointly. In power cranes provision should be made for 3 accelerating the speed of the trolley travel whenever the nature of the works admits of it. The best possible result is attained when travel of the trolley is effected with- out varying the vertical posi- tion of the load, and without Z causing useless movement of the hoisting chain or rope over the sheaves through & which it supports the load, - which movement would in- volve much additional fric- = tion, and cause rapid wear of the chain or rope. In traveling cranes a point of great importance is the parallelism of the bridge travel with the longitudinal tracks. Any defect here re- sults in increased resistance to traction, and any consid- erable error might cause derailment. In traveling cranes as heretofore built the use of flanged wheels has been relied upon to prevent derailment, and the propulsion of the bridge has been effected by a transverse shaft extending the whole length of the bridge, and connected by gearing with the truck wheels supporting each end of the bridge, so that by revolving the shaft the truck wheels would be ro- tated, and the bridge be thereby propelled, provided the adhesion between the wheels and the rails was sufficient. In some in- stances, where the adhesion has not been sufficient to prevent slipping, a cast-iron rack has been laid adjacent to the longitudinal tracks and extending their whole length, and pinions, gearing into this rack, attached to the axles of the truck wheels, so that pro- pulsion is effected independently of the adhe- sion of the truck wheels to the track. Ifthe load were always central on the bridge, and the motive power always applied to this shaft at the center of its length, this plan would answer well, although it is somewhat clumsy ; but in practice the load is constantly varying in position, and the motive power is ap- plied at one end of the long traverse shaft, * Read at the Cleveland meeting of the Ameri- can Society of Mechanical Engineers. so that torsion of the shaft induces a consid- erable variation in the travel of the opposite ends of the bridge. This error is a con- stantly varying one, according to the por- tion of the load resting upon each truck, as | determined by the position of the trolley, the load being never equally distributed between | the two trucks except when it is exactly in the center. It follows, therefore, that this system of bridge travel, although operative, is | radically defective, and that its use involves and entails a proportionate amount of wear | and tear of rails, wheels and driving gear. A better and more simple method of bridge propulsion has lately been introduced, by |means of which the longitudinal motions of BLAST FURNACE HOISTING | the bridge are effected by pulling each of its |ends, simultaneously and at equal speed, in the desired direction. For this purpose light wire cables are used, which, by a very | simple and ingenious arrangement of guide- sheaves, are made to act as a ‘‘ squaring device ” to hold the bridge/at all times perpen dicular, or square, to the tracks upon which | it travels. By this system the friction of trac- | tion is reduced to a minimum, and the danger | of derailment from unequal travel of the op- posite ends of the bridge entirely obviated. From the ebove facts it becomes evident that a perfect system of bridge propulsion must hold the bridge always absolutely square with its tracks, and must propel the | jopposite ends of the bridge in the same direction, at the same time and at the same speed, however unequally the load may be | distributed. It is desirable also that, in large cranes at least, provision be made for starting the bridge slowly from a state of rest, and then increasiny the speed, and also for vary- ing the speed while the bridge is inmotion. CHAINS VS. ROPES, AND CHAIN-WHEEL VS. DRUMS. In almost every type of crane the load is a constant loss of power by need'ess friction, | ENGINE, | the chain- wheel becomes impossible. | primarily carried upon a flexible cord of some kind. This usually consists of rope, either hemp or wire, or of chain. Each of these has distinctive merits and objections | Ropes have the advantage of being formed of many parts or fibers, so that no splicing or welding is necessary in their manufac- ture, and they thus have an assured and practically uniform strength throughout their length. Chains, on the contrary, con- sist of a series of independent links, each of which is formed from a straight bar, and | welded, so that a single imperfect weld |injures the whole, the strength of a chain being obviously limited by the strength of its weakest link. By care and good workman- ship, however, this danger can be avoided, BUILT BY THE CRANE in which case the chain becomes as safe as the rope, and much more durable. Where a rope is used, the hoisting gear must necessarily include a drum or barrel upon which the rope is wound up when hoist- ing takes place. Chain may also be thus wound up on a barrel, and this has hereto- fore been the common practice when chains have been employed in crane construction, and a prominent feature in cranes of large capacity has usually been a proportionately large ‘‘ winding barrel ” to receive the chain. A chain, however, admits of another mode of construction, which consists in substitut- ing for the wide barrel or drum a pocketed ‘*chain wheel,” consisting of a narrow wheel or sheave, of a width only slightly greater than that of the chain, and having formed upon its periphery a series of indentations or ‘‘ pockets,” exactly corresponding in size and shape with the links of the chain, so that the chain and the pockets fit together accurately, and slipping of the chain upon It thus follows that rotation ef the chain-wheel causes positive motion of the chain at a speed equal to the circumferential velocity of the BROS. wheel, in a manner precisely similar to the motion of a rack driven by a pinion, or of one spur-wheel driven by another. To be used in this way, it is necessary that the chain should have a constant and uni form ‘*‘ pitch”—that is, that every link should be exactly alike—so that the distance from link to link shall be always the same (just as in spur- gearing the spacing, or pitch, of the teeth must be uniform), and also that the pitch or spacing of the pockets of the chain- wheel corresponds accurately with the pitch of the chain. If this be done, and if the chain have a cross section of such area that when carrying the full load it is not strained to its elastic limit or to a degree which will cause any permanent elongation of its links, ILL. MFG. CO., CHICAGO., then a chain may be thus used, in engage- | ment with a pocketed chain-wheel, as well and as safely as on a barrel, Indeed, a properly-shaped wheel of this kind is much easier on the chain than a winding barrel or drum, for the reason that the latter has a | cylindrical surface, while the bearing face of the former is not cylindrical, but polygonal, the bed or bottom of each pocket being tan- gential to the radius at its center, and so pre- senting a flat surface for the parallel sides of each alternate link to bear upon. When the chain is wrapped upon a cylindrical barrel, on the other hand, the straight sides of every alternate link, being tangential to the sur- face of the barrel, can each touch it at one point only, the link being unsupported throughout the rest of its length, and the tendency of the strain induced by the load is to bend each of these links to the contour of the barrel. This effect may be easily seen in any chain which has been wrapped, under severe strain, upon a cylindrical barrel, un- less the diameter of the barrel be very large. The spiral grooving of a barrel does not remedy this fault, although it affords a much better bearing for the chain than a plain cylinder, which latter is only permissible for small chains and light loads. For heavy cranes hemp ropes are rarely used, owing to the size and multiplicity of parts required, and to their rapid wear. They are also inadmissable where liable to be exposed to much heat, as, for instance, in a foundry. Wire ropes are more available, and are often employed, but these also wear rapidly, unless the sheaves and barrels around which they pass are of large diameter, while this requirement, if met, reduces the effect ive hight of hoist and necessitates more parts or gearing to obtain the necessary purchase, and augments the bulkiness of the machine. Either material involves resort to a large winding barrel ordrum. The usual and best device for large cranes is well-made chain, and this, when used with pocketed chain- wheels and sheaves, gives the best and most satis actory results, and leaves nothing to be desired. The adoption of this plan dispenses with winding barrels, preserves the shape, and therefore the durability, of the links of the chain, and in every way simplifies and compacts the mechanism. The relative merits of the several systems may now be summed up as follows : (1) As to the Sustaining Cord. Hemp Ropes.—Admissible only for small cranes not in frequent use and not exposed to the weather or to heat. Wire Ropes.—Available under any ordinary conditions, but involving a winding barrel of large diameter and large sheaves ; not eco- nomical of space. Chains.— Pe ssessing, if well made, all ad- vantages and the greatest durability ; com- mon chain, requiring a winding drum, but permitting it and the sheaves to be of smaller diameter than with wires rope ; pitch chain, dispensing with a drum and admitting of the use of a narrow chain-wheel. (2) As to the Winding Device for Hauling in and Paying Out the Rope or Chain. Winding Drums or Barrels.—These must have a diameter and length such as will ena- ble them to receive the whole length of rope or chain to be hauled in by winding it upon their surface in one coil, without overlapping. In large cranes the load is usually carried upon four, six, or even eight parts of rope or chain, so that the length to be wound up amounts to four, six or eight times the ef- fective hoist, and the dimensions of the bar rel thus hecome very large. Moreover, this barrel must either be caused to travel longi tudinally on its shaft, so that the repe or chain, as it leads off, shall be always in the center of the crane and hoisting mechanism (which method of construction involves seri- ous complication and greatly widens the space occupied by the gearing), or the rope or chain, as it uncoils, be permitted to vary in position from one end to the other of the barrel, in which case it is nearly always out of center, thus inducing ob jectionable lateral strains and causing greater friction and wear. Chain Wheels, with Pock- ets.—These require a width only slightly greater than a single part of the chain, and a diameter merely sufficient to give the proper engage ment with it, so that both dimensions become much smaller than in a winding barrel, and the total occupied is but a small frac tion of that required for the latter The chain- wheel is fixed in direct line with the chain, andall lateral strains are avoided, while the flat bearings afforded for the chain by the pockets preserve Space device the shape of the link. and protect them from bending strains The slecK chain after passing over the wheel falls into a proper receptacle below. From this analysis of the facts is deduced the propos! tion that chains, if well made, constituts the best form of flexible cord for sustaining the load in a crane, and that a well-constructed chain wheel (as contradistinguished from a winding barre!) is the best form of device for hauling in and pay ing out the chain, and, therefore, that th: best method of crane construction involves the use of these two elements TROLLEYS AND TRUCKS The trolley of a crane is the moy riage from which the load is immediately suspended and by which longitudinal motion of the load upon the jib, or the b idge of a crane, is effected. The term truck is usually restricted to the wheeled carriage used to support each end of the bridge of a travel able car ing crane, or the corresponding part of rectilinear cranes of all kinds Rectilinear cranes usually at least one trolley require and one or more trucks. Rotary cranes ré quire usually a trolley only The whole load of a crane is hung primarily upon the trolley, and where trucks are used is transferred in full to them, together with the weight of the crane itself. It is desi: able, therefore, that these parts should n only possess ample strength to resist the strains they may be subjected to, buf also that they be so arranged that any yieldi: or breakage of their parts will not allow the load to fall to the ground, but only permit re eee 2 THE TRON AG ANSONIA BRASS & COPPER CO., No. 19 Cif Street, Prelps Building, NEW YORK, MA*UFACTURERS OF BRASS ANO COPPER Sheets.

For this reason the construc tion should be such that the ends of the bridge, in traveling and similar cranes, over- lap the longitudinal tracks, and the axles or housings of the trolley, in cranes of all kinds, overlap the rails upon which it runs. It is further desirable that the vertical distance between these overlapping parts and the rails be as small as possible, so that, in the event of any break occurring, the distance through which these parts pass before being arrested is so small that no serious shock can ensue. With careful designing this distance can be reduced to merely the necessary clearance of the parts, which need not ex- ceed more than ¢ inch or less. A natural preference exists for wrought |iron rather than cast iron as the material | from which to construct the moving parts of a crane, and, unquestionably, it is always best to use wrought iron for parts that are to be exposed to tension under heavy loads. Cast iron, however, is the better material for those parts that are subject to compression, | and by skillful designing it is usually possible so to arrange the parts of trulleys and trucks stiffness or re- sistance to compression is required, while still employing wrought iron for the parts under tension. In this way the greatest economy is attained, and not unfrequently a better result secured than by the use of either material alone. The wheels both of trolleys and trucks should be true cylindrically, should be double flanged, and, by preference, should have If wheels of small diameter are used in order to economize hight, they should be provided with anti-fraction bush- ings, to counteract the increased resistance to traction caused by their small diameter. The wheel-base or distance from center to of the adjacent wheels should be as large as possible, in order to avoid cramping between the rails, and to facilitate the easy motion of the carriage upon its track. In large travel ing cranes it is desirable that the axles of the truck-wheels be supported in spherical bearings, so that the wheels may adjust to any yielding of the track which may result from the passage of heavy loads, and thus all unnecessary straining of the parts of the truck be avoided. GIRDERS, In the early building of cranes, timber was chiefly used in the construction of their framework, and is still much employed in this country. Improvements in the manu- facture of structural irons, and the large variety of shapes now obtainable, have, how FRAMES AND products. } 3 Consumers are the ones most benefited by this condition of things, since it enables them to procure products of higher quality and ultimately at a Where such specialists exist, the best result is usually attained by submitting to them a clear statement of the work to be done and of the surrounding conditions, and by acce pt ing the advice thus obtained as to the type or form of machine best adapted to meet the special requirements of the case. lessened cost. In the very animated discussion which fol lowed the reading of this paper, Mr. Thos. R. Morgan, of Alliance, Ohio, gave an in teresting account of some English cranes made by Appleby, and also some cranes of his own—one being in use at the Dickson Mfg. Co.’s shop—which he had recently constructed, and which are now in use. He laid considerable stress upon the fact that the rack gearing alongside of the track, intended to preserve parallelism, was not at all necessary. He did not believe there was any great danger to the parallel ism of traveling cranes when a line of shaft ing ranacross them. Double flanges he re garded as an extra safeguard, and of worm gearing he seemed to have a very small opin ion, especially where a large amount of powe1 was to be transmitted. The crane built for the Dickson Co. has no worms, and the mo tive power is a square shaft running longi tudinally through the building. This is , inches on a side, and is welded up soas to be in a single piece from end to end, and is 200 feet long. In regard to the economy of such cranes, Mr. Morgan said that they had formerly found a gang of or 30 men and a foreman necessary. Natu- rally, the labor bill running high, for 15 tons in a single piece was only an ordinary weight with them. When they got the crane, how ever, the number of labor ers was vastly diminished, and a 14-ton cyl inder and piston was weighed and placed upon the top of its frame with remarkable ease. ihe lift was some 6 or 7 feet, all three motions of the crane were running, and it was placed in 7 minutes. We understood Mr. Morgan to say that the whole was ac complished by the aid of one ortwo men. A very high compliment was paid by Mr. Mor- gan to the Frisbie clutch, which he has adopted in his machinery. Near the tension rods by which the cranes are controlled are little signs, each containing a single word. These are, ‘‘ up,” ‘* down,” *‘ slow,” ‘* quick,” ‘*in,” ** out,” “‘ left,” ** right,” with another for the “‘brake.” By this means it is easy for any one to learn the management of the crane, and for orders to be given without 25 was | confusion, ever, greatly altered the relative cost of con- | and iron, and made it iron much more largely struction in timber possible to employ 1 than formerly. Experience in the practical designing and building of cranes of many types has con- vinced the writer that, by the proper use of materials, crane construction in iron costs, in most cases, little, if any, more than in wood. For example, the frame of an ordinary jib crane consists of three principal members— the mast, the jib and the brace. If of iron, each of these consist of a single piece of bar, or, in larger cranes, of two parallel pieces, and the union of these several members at their intersections is accomplished simply and very economically. If timber be used, on the other hand, more or less trussing is re- quired, except for small cranes, and many bolts, washers and castings are necessary to provide for the proper bearing of one part | upon the other, and to securely fasten the several parts together. The iron frame, when once properly put together, is practi cally imperishable. If properly painted it will not deteriorate, nor is it affected by ex posure to the weather, or by extremes of heat and cold. A timber frame, on the con trary, is liable to decay, which is hastened by exposure to the weather, and it is unfa- vorably affected by heat. More or shrinkage of the timber always thereby relaxing the engagement of the sev eral parts, and disturbing the relations of the bearings which receive the strains caused by the load. The result of these changes in a timber frame is to permit more or less work ing of the parts one upon the other, This tends to augment the trouble from which it arises, and asa result the safety of the crane its durability continually less occurs, is lessened and impaired. So also in the bridges for traveling cranes. If the span be great, construction in timber involves much splicing, and this in turn ne- cessitates unnecessary material in many places. The trussing and boltihg requires a considerable amount of ironwork, and usually necessitates a deeper girder than is required in iron, thus lessening the availa It is be- comparison of the costs of crane frames or girders wood and in iron, if proporticned with an equal factor of safety throughout, would show little, if any, economy of first cost in favor of wood. The availability this kind has been greatly ability of the mills to produce extreme lengths when required. No difficulty is now experienced in this country in obtaining the heaviest channel and I-beams in lengths of an accurate for structures of increased by the of iron | co feet or more, and the largest angle irons are also obtainable in single lengths of 8v or | go feet. It thus becomes possible to form each of the principal members of cranes of a single continuous iron, the advantages of which are too obvious to need description It will be that iron frames and girders are much to be preferred for every reason, with the single exception of possible conceded economy of first cost, Taking into account however, all of the conditions and consider ations above mentioned, it is believed that the difference in first cost is so slight—in many cases not appreciable—that the frames and girders of cranes of all, except, perhaps, the smaller kinds, should now be built en tirely of iron In conclusion, it may be foregoing analysis will conduce understanding of cranes, both their various forms or types, and the more important details of their construction Phe tendency of the day in all directions is to ward the specializing of products—that is, hoped that the to a cleare: as regards the concentration of the abilities and re sources of individual establishments upon the development of certain distinct or special In the afternoon the discussion of this sub- ject was resumed, and Mr. Durfee put upon the blackboard a drawing of a very peculiar crane, which he had designed some 10 years ago for lifting the rollers from a rail train. It was made in a very peculiar form, being a traveling crane in which end moved on an elevated rail and the other end was sup- ported on the floor, the crane and its bracing having a sort of [~ shape. The vertical part of the crane was an A or gallows frame supported on rollers. Referrmg to the subject of chains, Mr. Walker pointed out the fact that, where they run over drums, the flat horizontal link ought never to touch the barrel of the drum. The vertical link should bear on the groove and the hagizontal one should be entirely clear, and he said that he thought the com plaint in regard to the destruction of chains arose chiefly from the fact that the hori zontal links wore on the cylindrical drum. Mr. Collins made a sketch on the black board, illustrating a method by which two drums could be used where it was desirable to avoid having a spiral groove on the wind ing drum. Each of the drums had the same number of grooves, and were placed close together, but the chain was wound around the pair in a spiral direction, the groove on one drum coming opposite the high place on the other. Of course, there is to this plan the objection of the binding force of the chain upon the two drums, which is exceed dingly destructive upon the bearings, but to obviate this a small shaft is placed between them, with a friction-wheel on the shaft bearing on the two drums, which then roll upon this wheel On this subject Mr. Oberlin Smith said : ‘It is the custom in a great many places where hoisting machinery is used to give the word of command in such termsas ‘ H’ist her down ;’ ‘ Now let her go;’ ‘ Let her run a little ;’ ‘There, now ;’ ‘That'll do;’ * Now let her go;’ * Run her outa little;’ ‘ Run one her back ;’ Whoa! there!’ and all such terms, sometimes in a very indistinct voice, and it is a source of danger, undoubtedly, especially with cranes where they move quickly, and there should be provided near the hoisting machine a card stating what words of command are to be given in all cases where words can be heard at all There are cases where there is so much noise that a code of signals should be adopted, but in most cases words can be heard if they are properly spoken, and, of course, they should be sharp and crisp, perfectly plain and definite, and the same word should ps mean the same thing I know, in one of the best shops in Philadelphia som: years ago, the practice was to say anythi: at all. A very frequent expression wa Hist her away now!’ My practice is to have a code of words which must be strictly adhered to—simply ‘ Up,’ ‘down, in ‘out,’ ‘east,’ ‘ west,’ o1 north,’ s« uth, Ls the crane happens to stand, and * stoy Just those nine words will manage an ordinary crane Of course, where there are more motions other words are necessa: but they can all be just as short as those; and if the workmen are allowed to use no others, and are trained in speaking distinctly and loudly it may in some cases save accidents,” Mr. Capen said *1] should like to sa in connection with the subject just ref | to by the gentleman, that it has bee: practice, Ininstru ting the eratol {cranes manufactured by the Yale & Towne Mfg Co., to take their directions from motions of the foreman or whoever may hay ha [ the job.
