IMPROVEMENT IN HEAD-RESTS.

Specification forming part of Letters Patent No. 162,784, dated May 4, 1375; application filed January 8, 1875.

To all whom it may concern Be it known that I, WILLARD M. WHITE, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements pertaining to Portable Head-Rests for Rail-Gar Chairs, and the like; of which the following is a specification, reference being had to the accompanying drawings, where Figure l is a perspective view of a headrest, embodying my said improvements. Fig. 2 is a View of the same in central longitudinal section. Fig. 3 is a vertical cross-section of the rest, showing the construction and arrangement of the screw-pin, clamp, and nut. Fig. 4. is a perspective view of the screw-pin detached. 1

The letters a 1) denote two clamp-fingers pivoted together by pin 0. The finger b has The inside of the finger a and pad I) are, by preference, padded with rubber, or thelike. Thetop of the finger clets into the top of the finger b, and there has the gear-segments a, into which mesh the threads or teeth ofthe worm-screw d, on the upper end of which is the thumb-diskd, by the rotation ofwhich the two finger ends are adjusted toward or from each other, as desired, so as to clasp to or unclasp from the back of a rail-car chair or thelike. In thetop ofthefinger ais the socket (1 into which sits the foot-adjuster e, the back side of which consists of a series of steps, by means of which the spring-standard f, the foot of which passes through the mo tise-clamp 0, can be adjusted at a desired angle. On the upper part of the spring-standard is supported the padded rest g, from the back of which projects the screw-pin i, the standard f passing through a mortise, 70, therein. On the outer end of the pin i is the thumb-nut a, bearing under it the clamp 6 bearing on the standard f, by means of which the rest 9 can be adjusted at a desired point on the standardf, and also have a rotary adjustment on the pin -i, which pin can, when free, turn or rotate in the rest. The screw-pin z'is made with a square or other flanged head, Z, that is free to turn in the rest g, substantially in the manner indicated in Figr3.

I claim as my invention- 1. The combination of the clamp-fingers a b, the former bearing the geansegment a, and the latter bearing the worm-screw d, all constructed and designed for use substantially as described.

2. The combination of the foot-adjuster 0 (its back consisting of a series of steps) and the standard f, substantially as shown and described.

3. The combination of the spring-standard f, rest g, pin '6, nut i, and clamp t substantially as shown and described.
