'UNITED STATES PATENT Orthica- B. MCDEVITT, OFBELVIDERE, ILLINOIS.

INIPROVED RAILROAD-CHAIR.

Specification forming part of Letters Patent No. 57,943, dated September 1l, 1866.

I ends of the rails are secured and held together in a peculiarly-constructed chair by means of a wedge driven into one side ofthe said chair, and in such a manner as to tight-ly bind it about and in contact with the rails, as will be obvious from the following detail description. thereof, reference being had to the accompanying plate of drawings, in which- Figure l is a plan or top view of the railroad-chair, and Fig. 2 a transverse vertical section taken in the plane ofthe line ze, Fig. l. 4

The drawings representthe railroad-chair made in two parts or sections, B and C, one of which, B, has a raised dan ge, D D2, along each ot' its edges, and extending in the direction of their length. One ot' these anges, D, is grooved out at E to receive one side oi the web F ot' the rails, the other side of which is held in a groove, F, made of suitable shape, l

on the other section or part, C, of the chair, this part C, as well as the other, D, extending under the rails, meeting at or near the center line of the same.

Gis a Wedge-shaped or tapering strip, by which, when driven in and between the raised iiange D of the chair-section B and-its other section, G, running in grooves H of the same, the two parts of the chair are caused to tightly bind and grasp the rails and fasten or secure them in and to the chair, to relieve which rails it is only necessary to drive out the said wedge G, and thus loosen the chair-sections and rails, as is obvious without any further explanation. v

To prevent the rails from moving laterally in the chair, they are each notched, as plainly shown in broken section at J in Fig. l of the drawings, in which corresponding-shaped projectious K ot' the sides of the chair tit.

I claim as new and desire to secure by Letters Patent- The combination of the chair made in two parts or sections, B and C, and the wedge G, when constructed, combined, and arranged together substantially as and for the purpose described.

B. MCDEVITT.
