UNITED STATES PATENT OEEIcEf JOHN `W. DRAPER, OF WILMINGTON, DELAVARE, ASSIGNOR TO HIMSELF AND ARTHUR C. STOWELL.

IMPROVED RAILWAY-CHAIR.

Specification forming part of Letters Patent N04. 57,816, dated September 4, 1866.

To all whom it may concern:

Be it known that I, J. W. DRAPER, of Wilmin `gtomDelaware, have invented an Improvement in Railroad-Chairs; and I do hereby declare the following to be full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters. of reference marked thereon. l

My invention consists ot' a railway-chair constructed, as fully described hereinafter, so that the rail, chair, and sleeper may be quickly and firmly secured together.

In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe the manner oi' carrying it into effect.

On reference to the accompanying` drawings, which form a part of this speciiication, Figure l is a side view of my improved railway-chair with the rails contined to the same; Fig. 2, a pla-n View of Fig. l, Fig. 3, a transverse section on the line l 2, Fig. l; and Fig. 4, a plan view ot' a portion ot' the chair.

Similar letters refer to similar parts throughout the several views.

The chair consists of three partsthe plate A and the two cheeks C C'. The plate A is of wrought-iron, -and is bent down at the opposite ends so as to form two anges, et a', Fig. 1,in which are holes x. The plate is laid transversely on a sleeper, X, the iianges a ct' fitting snugly to the sides of the sleeper, to which the plate is then secured by spikes, which are driven through the openings a. In the center of the plate is a recess or depression, b, adapted for the reception ot' the bases of the rails B B', and at each side of the recess b portions of the plate are bent upward so as to form lugs ,c c c' c', the inner faces of which are inclined or beveled, as shown in Fig. 3 ot the drawings. i

The'lower edges ofthe cheeks C C' are beveled to correspond with the inclined faces of the lugs c c', beneath which they tit, While their inner faces are adapted or nearly adapted to the sides of the rails. The cheeks are retained in contact with the rails by bolts D D',

each of'which passes through openings in the cheeks and through a slot in one of the rails, and has at its outer end a nut, e. The tightening of the nuts has a tendency to force the lower ends ot the cheeks outward and cause them to bind hard against theilugs c c', dto.

When it is necessary to remove one or both the rails, the `bolts D D' are withdrawn, and the cheeks are detached by moving them upward in the direction of the arrows, Fig. 3, after which the rails may be lifted from the plate.

In chairs of the ordinary construction the rails are generally secured by means of bolts, the strains and jars on which are apt to loosen the nuts. The ordinary chairs also are secured to the sleepers by spikes, which are driven vertically through openings in the chair into the sleeper, so that in a comparatively short time the constant jars occasioned by the passage of trains over the rails loosens the spikes, and sometimes displaces the chairs.

In'the above-described chair, although the cheeks C C' are contined to the rails by bolts D D', the nlatter are not in a position to be affected by shocks or jars, the main strains to which the chair is subjected being received by the lugs c c'.

By inserting the spikes laterally through the anges t a' into the sleeper, their `withdrawal by the ordinary strains and jars is efi'ectually prevented, and the necessity of constantly employing laborers to examine the chairs, replace lost spikes, and secure those which are loose is avoided.

The combination of the plate A, its beveled lugs cc', cheeks C O', and bolts D D', the whole being constructed, arranged, and adapted to the rail substantially as and for thev purpose specied.

In testimony whereof'I have signed my name to this 'specification in the presence of two subscribing witnesses.

JOHN W. DRAPER.
