WILLIAM H. PECKHXMVI, OF NEW YORK, N. Y.

IMPROVED RAILWAY-CHAIR.

Specification forming part of Letters Patent No. 47.747,'dated May 16, 1&7565.

To all whom it may concern:

Be it known th at I, WILLIAM H. PECKHAM, of' New York, in the county of New York and #State ot' New York, have invented new and useful Iinprovementsin Railroad-Chan s; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to mike and use the same, reference being had to the accompanying drawings, forming a part of this specification.

In the accompanying plate of drawings my improvements are represented, Figure l being a plan or top view of a portion of a railroad with my improvements applied thereto; Fig. a transverse vertical section in plane of' line .r Fig. l; Fig. 3, a section in plain ot' line y y, Fig. 2.

'lhe present invention has for its object the firm clamping and holding ofthe rails at their points of junction by a new and peculiar arrangement of the chair.

a a a, Src., in the drawings represent the ordinary rails of railroads fastened in the usual manner by spikes b b b, Ste., to sleepers or cross-ties c c c, Sac. d d, my improved chair placed at the junction ot' two contiguous rails, and made as follows ffand g g are twojaws, one of which,g,is securely fastened to or forms a part of a horizontal plate, h, while the other, f, is free to play back and forth from and toward the fixed jaw g, being guided by the projecting piece h, moving and properly held in the opening k of the plate H. The interior faces, z' ,'of the jtws conform to the contour of the side surfaces of the railsm. A stationary post fastened t) or forming a partof the plate la and on the saine side with the jaw f. Through this post m/loosely passes a horizontal screw-bolt, n, extending toward and entering a socket, o, in the jaw f, in which it comes to a bearing. (iSee Fig. 2.) On this bolt n, between post m and jawj', and bea-ring against the post, is a screwnut, s, by the turning of which to the right or left the movable jawf, as is evident, is made to travel to or from the `tired jaw g, as may be desired.

The chair as thus constructed is placed as usual at thejunction of two rails, with its fixed jaw in close contact with the rail, the rail passing between the twojaws and over its plate It and fastened by spikes, screws, or other proper means to the cross-ties. The nut s is then turned so as to move the jaw f toward the rails, against which it is thusV brought to bear and with any desired amount of*pressure, firmly clamping and holding the rails between the chair-jaws.

To prevent the turning` ot' the screw-bolt n within its two sockets as its nut is turned a square head can be formed on its inner end, as represented in Fig. 2.

Having thus described my invention, I claim as new and desireto secure by Letters Patent- The railroad-ch air herein described for clamping and holding the contiguous ends of rails, the same consisting of a movable jaw or jaws made to form a close bearing with the sides of the rail by means of one or more screw-bolts and nuts arranged and operating as described.
