UNITED STATES WILLIAM WARNER, oE PHILADELPHIA, PENNSYLVANIA, AssIeNoE 0E ATENT OFFICE.

ONE-HALF OF HIS RIGHT TO SAMUEL MGMULLIN, OF SAME PLACE.

Specification forming part of Letters Patent No. 129,697, dated July 23, 1872.

Specification describing certain Improve inents in Horse-Oar Railroad Chairs, invented by WILLIAM WARNER, of the city of Phila: delphia and State of Pennsylvania.

The first part of my invention relates to the combination of a clamping-plate with the chair and the contiguous ends of the rails in such a manner as to hold them securely upon the string-piece. The second part of the invention relates to providing the bed-plate with flanges on its upper and under sides, which fit against the edges of the rails and string-piece to prevent the lateral movement of the rails, as hereinafter fully described.

Figure l is a plan view of the chair in connection with a string-piece,13, and the contiguous ends of the rails (J (3. Fig. 2 is aside elevation of the same. Fig. 3 'is a crosssection at the broken line a b of Fig. 1 Fig. 4i-is an isometrioal view of the chair A. Fig. 5 is I a like view of the cap-plate E in a reversed position.

Like lettersin all thefigures indicate the same parts. I

A is the improved chair, whose bed-plate a is let into the string-piece B and level with the same, so as to provide a firm foundation for the ends of the rails. O O are contiguous ends of the rails, which bed on the bed'plate a. The treads b of the rails are level with the tread b of the chair, and the clamping-plate E beds upon the face 0 of the rails and the raised part a of the bed-plate. The clamping- Fig. 2, through the string-piece B and the staple G, which projects from the under side of the said clamping-plate into a suitable mortise of the string-piece, thus holding the parts firmly together and preventing the ends of the rails springing up when relieved of the pressure of the car-wheel upon them. The clampin'g-plate E is of such height as to be borne upon by the flanges of the car-wheels as their treads roll over the treads b of the rails G O and the connecting-tread b of the chair A, so as to relieve the joints of the rails of a 1 portion of the weight of the car, and thus prevent the usual rapid wear and rubbing off of the corners.

A saving in the expense of rails is effected byconstructing the chair with the tread b.

The checks d d of the bed-plate afit against the edges of the string-piece B, and the rails G 0 have a lateral support against the flanges ff of said plate, to prevent the lateral movement of the rails.

I claim as my invention-- 1. The combination of the clamping-plateE, provided with a staple, G, the chair 1A, rod F,

and spring-piece B, through, which it passes for holding the rails and chair firmly upon the string-piece, substantially in the manner above set forth.

2. The combination of the cheeks d d and flanges f f of the bed-plate a with the edges of the string-pieceB and the edges of therail G C, respectively, for preventing the lateral movement of the rails, substantially as described.
