CHARLES GILBERT HAWLEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO FREDERICK A. GALE, OF CHICAGO, ILLINOIS.

NORMAL-SURFACE TRANSFER-TABLE.

To all whom it may concern:

Be it known that I, CHARLEs GILBERT HAWLEY, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Normal- Surface TransferTables, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in means for shifting locomotives and cars laterally from one track to another, and the invention has special reference to improvements in transfer tables and yards as constructed and employed in and about railroad shops and depots.

The object of my invention is to provide means for transferring rolling stock from one track to another and, primarily, to provide means of such character as to obviate the use of the usual pit and permit the practically unrestricted use of the transfer surface or area for all the traffic that may be necessary between and about the shops or depots.

The particular object of the invention is to provide a normal surface transfer yard, without the usual pit, and which shall be provided with or contain a suitable arrangement of diagonal and cross tracks necessary to ordinary traffic, and which shall also have a transfer table movable from end to end of the transfer yard and adapted to receive rolling stock from numerous nor mal level switching tracks and shop tracks or stalls, which latter terminate at the edges of the surface traversed by thetable.

In carrying out my invention I do not dig a pit in which to operate the transfer table, but utilize the normal surface of the yard and construct a low table adapted to serve the tracks which abut or terminate at the transfer surface. The term transfer surface as here used is intended to designate the surface which is traversed by the transfor table.

My invention may be further defined as consisting broadly, in a transfer yard which is traversed by through and switching tracks, combined with a transfer table adaptedv to move from end to end of said yard, numerous stall tracks, leading up to Specification of Letters Patent.

Application filed September 24, 1906.

Serial No. 335,887.

the surface which is traversed by the transfer table, to deliver or receive rolling stock thereto or therefrom, and means for interrupting certain of said through or switching tracks to permit the passage of the transfer table and also to permit the connection of the transfer table therewith.

My invention further and particularly consists in novel cross track rail sections which are adapted for operation to inter rupt said tracks at times when it is necessary to move the transfer table across said tracks or connect it therewith.

My invention also consists in a transfer table of novel construction, particularly adapted for use upon a normal transfer surface.

Further my invention consists in various details of construction and in combination of parts, all as hereinafter described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which;

Figure 1 is a dragrammatic plan of a section of a transfer yard constructed in accordance with my invention, showing tracks crossing the normal surface occupied by the transfer table tracks; Fig. 2 is a plan view of my normal surface transfer table and tracks together with certain alining or connecting devices included in my invention; Fig. 3 is an enlarged vertical section on line aa of Fig. 2 Fig. 4 is an enlarged vertical section on line bb of Fig. 2; Fig. 5 is an enlarged .detail section on line 0-0 of Fig. 2; showing the inclined sections in position to connect two portions of a cross-yard track; Fig. 6 is an enlarged detail section on line dd of Fig. 5; Fig. 7 is a plan view of the transfer table; and Fig. 8 is an enlarged cross section thereof, on line e-c of Fig. 7.

In Fig. 1 the rectangles, 1 and 2, represent two buildings, such as two depots or sheds, or a railroad machine shop and a locomotive boiler shop. The ground or surface, 3, between the buildings is level and about midway between the buildings, and preferably parallel therewith, I arrange a plurality of transfer table tracks or rails, 4. These rails are laid upon suitable ties or sleepers and are sunk in the ground, so that their tops are substantially flush with the surface of the yard. The rails define or outline what I designate as the transfer surface, as distinguished from the transfer yard, by which latter is meant the entire surface between and adjacent to the buildings. The transfer surface is as long or longer than the buildings and at its ends may be traversed by through or switching tracks 55. The end or intermediate portions of the transfer surface may likewise be traversed by diagonal incoming or outgoing switching tracks, 6. The through or switching tracks, 5 and 6, that extend across the transfer surface, 4 comprise end sections, 5 and 6, respectively, outside of the transfer surface, and intermediate sections, 5 or 6, are sunk in the ground with their tops in the plane of the tops of rails, 4. The end sections of the tracks 5 may have their bases flush with the normal surface of the yard, that is above the ground. The end sections, 6, are inclined to join the intermediate arts, 6. A plurality of stub tracks or staff tracks, 7, are laid from the buildings, 1 and 2, and terminate at the edges of the transfer surface, 4. These tracks are laid upon the ground, the ties only being sunk therein.

It is necessary to lay the intermediate track sections, 5 and 6, at the same level as the transfer tracks, 4, in order to avoid leaving gaps in said track sections. Therefore, said intermediate track sections will be at a lower level than the yard tracks.

Any through or switching track that need not be connected to the transfer table 35, is laid continuously, as indicated by tracks, 6, in Fig. 1. But each through or switching track that is to be served by the transfer table, I rovide with certain movable track sections, ocated within the transfer surface, and capable of interrupting the through or switching tracks to permit them to be con nected to the transfer table. The track-interru ting devices hold the tracks normally close for traffic, and are only displaced to permit the transfer table to pass, or stop, thereover. As shown in Fig. 2, said devices are mounted on metal blocks, 8 and 9; the former being positioned within the transfer surface against theend of the track section, 5, with its upper surface flush with the transfer surface, as shown in dotted lines in Fig. 5. This block is preferably wider than the track, 5, in the direction of its own length, for the purpose hereinafter made clear. As the lock, 8, intersects one or more of the transfer table tracks, 4, the latter are cut away to receive it, as shown. The other block, 9, may or may not be set into a transfer table rail, but is positioned several feet inwardly I from the block, 8.

The movable track sections, 10, are in the form of tapered blocks which, when normally disposed, connect the end track section, 5, to

the intermediate track section, 5, being downstruction.

wardly inclined from the former to the latter, and their inclined surfaces being provided with wheel-flange grooves, 10.- On one side, which may become the upper side, they are also provided with wheel flange grooves, 1 1, that register with flange grooves, 11, formed in the to of the block, 8; said grooves registering with the outside or marginal transfer rails, 4. Each of said movable track sections, 10, is provided upon its ends with pivot studs or trunnions, 12 and 13, mounted in bearings in the blocks, 8 and 9, respectively. Through the block, 8, at the larger ends of said arms, passes a rock-shaft, 14, on which are fixed two lifting arms, 15, that respectively engage the track sections, 10, and are so positioned that when laid flat they permit said sections also to lie fiat upon them, and when raised (by turning shaft 14) will turn up the sections, 10, to operative position. When thus turned, the arms, 15, lock the track sections, 10, against stops, 16, secured on the block, 8 thus said track sections are made immovable until the rock arms, 15, are lowered. Rock-shaft, 14, is actuated by a lever, 17, through the medium of a rod, 18, and an arm, 19, fixed on said shaft.

As shown in Fig. 6, the metal block, 8, is formed with an upwardly extending portion, 8, that fits against the end of the yard track, 5, and is provided with wheel-flange grooves, 20, registering with said track, and with the longitudinal flange grooves, 10, of the movable sections, 10. The block, 8, is provided with recesses that receive the track sections, 10, when the latter are in the position shown in Fig. 2; thus the passage of the transfer table wheels over the block, 8, and members, 10, will be smooth and unbroken when the latter are down. The block, 9, that supports the inner ends of the movable track sections, 10, is provided with wheel-flange grooves, 5", that register with the track section, 5, and with the corresponding grooves, 10, of said movable sections.

When the transfer table 35 is to be moved across, or connected to, one of the through or switching tracks, the movable track sections, 10, of that track are thrown down by an operator, so that they will permit the transfer rails to register with the track section, 5, or permit the transfer table to pass over them, I as the case may be. It will be evident that rolling stock may be transferred between any track, 5 or 7, upon the transfer table, regardless of the fact that some of said tracks extend across the transfer surface. The transfer table 35 is preferably constructed as shown in the drawings, whereby it will combine ample strength with cheapness of con- The table comprises a plurality of continuous transverse cast-metal crossbearers, 24, carrying-wheels, 25, and a pair of longitudinal channel stringers, 23, which hold the rails, 22. The table also comprises an extended platform, 26, supported by two elongated cross-bearers, 28, and by track-wheels, 25. The cross-bearers comprise depressed load-bearing portions, 24, and connecting portions, 27; those supporting the platform, 26, comprise also the extensions, 28.

29 and 30 represent longitudinal reinforcing ribs on the cross-bearers, the lower of said ribs being recessed as shown to receive the axle-ends, 31, while permitting the crossbearers to be lifted off the wheels. The depressed load-bearing portions, 24, are provided with strengthening ribs, 32. Each intermediate cross-bearer is supported by a single row of wheels, but the bearers at the ends of the table are preferably mounted on two rows of wheels, arranged in pairs and connected by short axles. All the crossbearers are slotted, as shown, to permit the use of wheels as large as practicable.

The channel stringers, 23, are fitted in the depressed parts, 24, of the cross-bearers and are provided with lateral flanges, 23, which are riveted to flanges, 29, of the cross-bearers. The ends of the cross-bearers are connected together longitudinally of the table by riveted channel-bars, 34. Thus the stringers, the cross-bearers, and these bars, 34, together form a very strong and rigid structure. The spaces between the two stringers, 23, are covered over by a floor plate, and the spaces alongside the stringers are covered by provided with bolt-sockets, 48.

plates, 36. Thus the table presents an almost continuous surface which is a convenience to operators and other workmen.

The preferred table-driving mechanism is constructed as follows: One of the longitudinal rows of wheels is mounted on a single extended shaft, 37, instead of upon separate axles. On said shaft is keyed a bevel gear wheel, 38, and that it may be as large as practicable, the wheels upon the shaft are larger than the other wheels. Gear, 38, is driven by a bevel pinion, 39, on the lower end of an inclined shaft, 40, which is driven through gears, 41, shaft, 42, and gears, 43, by a motor, or engine, 44. The motor, 44, is also geared to a winding drum, 45, to which a draft cable (not shown) may be attached, for use in drawing on cars or locomotives in the absence of a live locomotive as a pusher.

Any suitable device may be employed for causing the transfer table to come to a stop in accurate alinement with a track, and for positively holding it in such position. The table holding device which is shown herein comprises bolts carried by the table and boltengaging parts positioned at the respective tracks. The stub or stall tracks, 7, are provided at their ends abutting the transfer surface with heavy wooden or metal ties, 47, The bolts, 49, carried by the transfer table are suitably mounted and operated, the details of this construction being immaterial. As the switching or through tracks, 5, are provided with the metal blocks, 8, the bolt-sockets, 50, are formed in said blocks, as shown in Fig. 2.
