AUGUST G. LIEIBMANN, OF CHICAGO, ILLINOIS.

RAIL-CHAIR.

Application filed January 11, 1916, Serial No. 71,583.

To all whom it may concern Be it known that I, AUcUs'r G. Line- MANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in RailChairs, of which the following is a specification.

This invention relates to railway track appliances and more particularly to rail chairs.

The object of the invention, generally stated, is to provide means for holding rails under all conditions of track and to provide for adjustment of said rails for both surface and gage without disturbing the primary fastening devices.

A further object of the invention is to provide a rail chair particularly adapted for use on semi-hard wood ties and which will effectually prevent creeping of the rails the bed plate of which is of rolled shape and provided with angular openings which register with correspondingly shaped socket members in the cross tie for the reception of the rail clamping members.

A still further object is generally to improve the construction of the rail clamping members, whereby a more efficient and positive holding means for the rails is provided.

Renewed June 13, 1918. Serial No. 239,876.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, A represents a rail having a standard cross section, and B the tie supporting the rail. Mounted upon the cross tie B is abed plate 5 preferably a rolled shape, although the plate may be otherwise formed, if desired. The bed plate 5 issubstantially rectangular'in shape and preferably extends the entire width of the upper surface of the tie, said plate having its opposite ends provided with upstanding abutments 6, the inner faces 7 of which are perpendicular to the upper surface of the bed plate, as shown. The lower face of the bed plate 5 is'preferably formed with a series of transversely extending substantially elliptical depressions 8 which serve to lighten the weight of the plate and also form in effect pockets which serve to receive the fiber of the wood when the bed plate is clamped in position on a cross tie. The bed plate 5is provided with spaced openings 9 disposed in staggered relation to the base flange of the rail and preferably octagonal in outline, said openings being adapted to register with openings 10 formed in the upper surface of the cross tie. Seated in the openings 10 in the cross tie are detachable sockets or, guiding members 11. The exterior walls of the socket members 11 are cylindrical, while the interior walls thereof are provided with a plurality of angular faces 12, preferably eight in number, p to correspond with the angular faces of the openings 9. The upper end of each socket member 11 opens through the upper surface of the cross tie, while the bottom thereof is provided with an opening 13 adapted to receive a primary fastening device, preferably in the form of a bolt 14. The upper end of each bolt 14 is preferably conical, as indicated at 15, and provided with threads 16 which en age a clamping nut 17, this clamping nut 1 by engagement with the bottom of the adjacent member 11, serving to hold the socket member on the cross tie. Each clamping nut 17 is provided with recesses or notches 18 adapted to receive a socket wrench and thus facilitate screwing the clamping nut home. If desired, however, the clamping nut 17, instead of being formed with the notches 18, may be provided with upstanding teeth. The bolts or primary fastening devices 14: preferably extend entirely through the tie and are provided with terminal heads, not shown, which bear against suitable washers on the lower face of the tie.

As a means for holding the rail A in different positions of lateral and vertical adjustment on the bed plate, there are provided interchangeable rail clamping members 19 each preferably octagonal in shape and provided with .an eccentric portion 20 having a plurality of angular faces 21 dapted to bear against the adjacent longitudinal edge of the base flange of the rail for shifting the rail laterally with respect to the bed plate when the clamping members are adjusted, said eccentric portion defining a circumferential clamping lip 22 for contact with the upper face of the base flange of the rail, as shown. Depending from the eccentric portion 20 of each rail clamping member is a sleeve or extension having a cylindrical bore -24 and a plurality of exterior flat faces 25 corresponding in number to and adapted to bear against the Hat faces 12 of the socket members 11. The head of each rail clamping member is in the form of a flange 26 having a plurality of flat locking faces '27 adapted to bear against the inner face 7 of the adjacent abutment for preventing accidental rotation of the rail clamping members after being once adjusted. The upper surface of the flange 27 of each clamping member is preferably formed with a plural ity .of radiating reinforcing ribs which merge into an upstanding flange 29 surrounding the bore 24:, the upper surfaceoi the upstanding flange 29 being provided with a flat face which forms a seat for a spring washer .80.

As a means for locking the rail clamping members in contact with the base flange of the rail A, there .are provided suitable screw caps 31, each provided with a depending cylindrical portion having internal threads for engagement with the threads 16 ot the adja cent primary fastening device or bolt 14, the exterior walls of the cylindrical portions of the screw caps being smooth and urob- .struoted for engagement with the corre spondingly smooth cylindrical walls llof the rail clamping members. The upper end of each screw cap is provided with an angular head 32 to permit the screw cap to be conveniently grasped with a wrench or other suitable tool in adjusting the parts. The washers 3O insure the desired compensation for recoil of the rails under. stress and at the same time keep the parts tight.

It will here be noted that the rail clampmg members 19 are disposed in staggered relation on the bed plate, while the bolts 14L not only serve to hold the socket members 11 on the cross tie but by engagement with the threaded walls of the screw caps serve to lock the rail clamping members in contact with the base flange of the rail. In

of the socket members 11 with respect to the upper surface of the cross tie, an increased range of vertical adjustment of the rail clamping members may be effected without the necessity of materially increasing the size or bulk of the rail clamping members.

In order to adjust the rail laterally on the bed plate for gage, it merely necessary to remove the screw caps 31 and position one of the rail .clan'iping members within .the adjacent socket member 11 with one of the angular faces of the large portion of the cocentric bearing against the base flange of the rail on one side thereof and with one of the angular faces of the short portion of the eccentric of the other clamping member bearing against the base flange of the rail on the other side of said rail, after which the screw caps are threaded on the bolts 14: and adjusted home which clamps the members 19 in engagement with the base flange of the rail and effectively prevents accidental displacement oi said rail. It will be understood that by moving the l clam ping members 19 to different positions of adjustment within the angular openings 9 of the bed plate and socket members 11, the rail may be shifted laterally in either directioufor gage, as required. In order to adjust the rail vertically for surface, the screw caps are retated to elevate the same and a shim 3d placed beneath the rail, after which the screw caps are tightened, as best shown in Fig. 2 of the drawings. It will here be noted that when the clamping members are adjusted, one of the flat faces of the eccentric of each clamping member is always in contact with the base flange of the rail, while one of the that faces of the flange 26 of each clamping member is always in contact with the adjacent abutment so as to form an efiective lock and thus positively prevent accidental rotation of the clamping members with respect to the bed plate. extensions 23 of the rail clamping members not only permit vertical adjustment of said rail clamping members, when shims-ling the rail for surface. but by reason of the engagement of the angular walls of the extensions 2 with the angular walls of the socket .members 11 serve as an auxiliary means for preventing accidental rotation of the rail clamping members. The socket members 11 being detachable may be readily The applied to the cross ties at the treating plant and are held against displacement during shipment by the clamping nuts 17. By makthereby materially reducing the cost of manufacture.

be seen that the improved chair provides for gage variatlons on curves and tangents pos1- tively prevents creeping of the rails with out the employment of rail anchors and provides for the restoration of gage without respiking and for rail surface variations and the like without respiking.
