NORMAL-SURFACE TRANSFER-TABLE.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed September 24, 1906. Serial No. 886,336.

To all whom it may concern:

Be it known that I, CHARLES GILBERT I'IAWLEY, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented a certain new, useful, and Improved Normal-Surface Transfer-Table, 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 sho s and depots.

he 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 ermit the practically unrestricted use of t e transfer surface or area for all the traflic that may be necessary between and about the shops or de ots.

In carryin out my invention I 0 not dig a pit'in whic to operate the transfer table, but utilize the normal surface of the yard and construct a low table adapted to serve the tracks which terminate at or abut the transfer surface. The term transfer surface as here used is intended to designate the surface which is traversed by the transfer table. Further particulars of my invention involving structures and arrangements whereby the tracks connection with the transfer table and involvin also the peculiar structure of the low movabi table will be described hereinafter. In the accompanying drawings which form a part of this specification, I have illustrated a preferred embodiment and manner of carrying out the invention, but it will be understood that my invention is not restricted to the specific construction shown in the drawings and hereinafter described in detail.

In said drawings Figure 1 is a diagrammatic plan view of a transfer yard and table embodying my invention, the transfer surface being shown as lying between two railroad shops, sheds or depots; Fig. 2 is a plan view of a portion thereof, enlarged, showing two tracks which extend directly across the transfer surface; Fig. 3 is an enlarged plan view of the transfer table; Fig. 4 is a vertical to be served are adapted for transverse section on the line w:c of Fig Fig. 5 is a similar view on the line y y of 1; Fig. 6 is an enlarged sectional view on the line z-z of Fig. 5; and Fig. 7 is an enlarged vertical section of the transfer table, on the line uu of Fig. 3.

As indicated in the fore oing, I lay the tracks which are to carry t e transfer table directly upon the surface of the railroad yard, preferably, however, embedding the rails in the ground .so that the tops thereof are flush with the normal surface.

Referring to the drawings, A and B represent two railroad shops, each containing a number of tracks, 11, to receive rolling stock; 2, represents the surface of the yard, and 33, are the transfer table tracks above referred to. Figs. 4 and 5 show the manner of laying the tracks, 3. Imay arrange these tracks in pairs as shown or may use single rails, according to the service to be performed. As indicated in Figs. 4 and 5, the ground is slightl depressed toward the middle of the trans er surface. My purpose in thus depressing the transfer surface will be explained hereinafter. The transfer table, 4,. ereinafter described in detail, is mounted upon wheels which roll upon the tracks, 33, and it is adapted to travel from one end thereof to the other. These rails 3, and the transfer surface defined thereby, are referably longer than the buildings, A an B to the end that the transfer surface may be traversed by through tracks, 66 from which rolling stock may be received for delivery to the shops or buildings, AB and likewise to which the same may be returned or delivered. It will be seen that as the normal surface of the yard between and about the buildings is not interrupted, the tracks, 6, and other tracks, 5, may all be laid upon the normal surface; that is, ma traverse the transfer area. I prefer that al rails trave'rsing said area shall, upon approaching the same, be sunk into the ground so that their tops will be flush with the surface, 2, and with the transfer table'rails, 3. The slight depression of the ground at the middle of the transfer area does not interfere with the passage of rolling stock upon the cross ties.

refer that the intersecting rails shall be oined by frogs, 7 as shown in Fig. 2. It will now be seen that I may construct my transfer yard upon a surface which is already occupied by' the numerous through and switching tracks necessary to the railroad shops or buildings, without interfering with the service upon said tracks and without removing or disturbing them beyond the necessary cutting and frogging of the rails. The tracks, 11, in adjoining railroad sho s are rarely directly opposite one another, ut in some cases they are so nearly in line that they may be connected by direct cross tracks, 6, as're resented in Figs. 1 and 2. These .tracks, lilie the tracks, 5 and 6, are sunk into the ground so as not to interfere with the movement of the transfer table on the rails,

66, may lead into one of 3. The tracks, the buildings or may be entirel outside thereof, as indicated in Fig. 1, it eing evident that the transfer surface may-be extended at slight cost to meet such outlying tracks and thus ada t the table to serve the same. The low rail s l0,'u pon the transfer tables, 4, stand only a few lnches above the marginal table-tracks, 3, but nevertheless, are too high to meet the stub ends of the track, 1, laid upon the marginal surfaces, 2. I therefore elevate the ends of said tracks, as shown in Fig. 4, bending the ends, 1, of the rails upward, and preferably supporting them upon rail-chairs, 8. The fixing of the ends of the rails at the height of the table in this manner enables me to dispense with movable arts or members which would otherwise he required to join thetable to the 'tracks, 1. An incidental advantage attaching to the elevation of the ends of the track, 1, is that they accidentally passing off the rails and onto the transfer surface.

As a means of connecting the cross tracks with the transfer tables at necessary times, I equip said tracks with movable members, 99, at points adjacent to the transfer surface. One of these members is shown in detail in Figs. 5 and 6, from which it will be seen that the track or table alining or joining device comprises a tapered or wedge-like block. or shoe, of the cross track or rail, 6. The u per surface of the shoe is preferably provi ed with a flange groove, 9, the wall of which merges with the inner side of the rail, 6 when the block is raised into position on the rail.v The block is pivotally fixed u on the ends of the ties at the side of the rail by means of arms, 9 plates, 9 and a pivot pin, 9. The normal positionof the wedge or block is at the side of therail, as shown by dotted lines in Fig. 6 and by full lines in Figs. 1 and 2. The block is only raised at times when the table is stopped at the track, 6. If

desired, mechanical means may be provided for throwing the blocks, but as a rule the are sufficiently light to be operated by han It is obvious that when the blocks 9, of any track, 6, are raised to register with the rails of the table the car or locomotive can be moved onto or taken from the table. In the bearers, 15, having journa s prevent rolling stock from absence of the table and when the blocks are down, the cross tracks, 6, are. open for through traffic.

. A distinct advantage of my invention is that the ground surface between the buildings is preserved at substantially uniform' level throughout, and as none of the rails project above the transfer surface, trucks and pedestrians may cross the transfer surface freely in all directions.

The table which I prefer to employ u on the transfer yard, of my invention is a lbw structure, comprising a lurality of cross for the axles, 12, ofthe carrying wheels, 13, together with a plurality of longitudinal members/ I prefer to use four wheels upon each cross bearer and between the pairs of wheels I depress the cross bearers, strengthening these portions by flanges, 17, and webs, 14: The depressions in the cross bearers receive the channel members, 20, which are continuous from end to end of the table and carry the low rails, 10.v Theends of the cross bearers are connected by continuous channels, 18, and top plates, 21 and 23, are employed to strengthen the table and withstand lateral strains. ,These plates also serve as a floor or path for pedestrians.- The middle portions, 16, of the cross bearers may if desired be omitted and links or flexible members substituted, and in any case said middle portions serve only to tie the trucks together and hence may be of less cross-sectional area than the loadcarrying .portions. Sagging of the floor plates is prevented by means of spliced plates,

24 'For driving the table,"I employ a motor,

30, carried by an extension, 25, of the table.

All except the end pair of wheels on one side of the table are connected by a shaft, 26; that is, the wheels are mounted on a single axle and this being provided with a gear, is connected with a motor through a train of gears, 27, 28 and 29. The extension or latform, 25, also carries acable winding rum 0r winch, 31, on which is wound the cable that is used in moving rolling stock that is dead, '5. e. that which is not moved by its own power. The carrying wheels at the ends of the table are of small diameter, and as it would be difficult to attach a driving gear to so small a wheel, I increase the diameter of the wheels beneath the middle portion of the table. At this point I have to explain that the desirability of larger wheels at these points for the reasons stated and also for the purpose of decreasing the resistance to the movement is .the sole reason for depressing the transfer surface. This being the case, it will be obvious that a different arrangement'of the supporting wheels would permit the employment of a perfectly level transfer surface, or even a surface crowned at the center.

The use and operation of my invention is as follows: A locomotive or car arriving at the shops upon one of the outlying tracks, 6, the blocks or shoes, 9, thereof are raised and the transfer table is moved into register therewith. The locomotive'is then moved onto the table, whereupon the table is started and asses along the transfer surface until a particular stall or stub track, 1, is reached. The table being here stopped in register with the raised ends, the locomotive or car may be readily driven-off the table and into the adjoining building. The operation of shifting rolling stock from one stall track to another is as above described, saving that in such casesnone of the shoes need be operated unless the stall track chances to be one of the straight through tracks, 6. It will be obvious that the table may be operated without interrupting the passage of cars or trains upon any of the through tracks.

As various modifications of my invention will readily suggest themselves to one skilled in the art, I do not confine the invention to the specific constructions and structures herein shown and described.
