H EAD-REST.

SPECIFICATION forming part of Letters Patent No. 430,731, dated June 24, 1890.

Application filed March 5, 1889. Serial No. 301,826. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM A. DOBSON and JUSTIN M. ST. JOHN, citizens of the United States, residing at Marion and Cedar Rapids, respectively, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Head-Rests; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of our invention is to produce a simple, cheap, and efficient head-rest, which may be conveniently attached to the back of a car-seat or chair, and when not in use may be folded compactly.

The invention consists in the construction, combination, and arrangement of parts, as hereinafter fully set forth and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a rear view of the device embodying our invention applied to a car-seat, as seen in perspective; Fig. 2, a front elevation of the same; Fig. 3, a rear elevationof the same folded, and Fig. 4 a side elevation of the same partially closed together.

Similar letters of reference indicate corre-' sponding parts.

Referring to the drawings, A A are two fiat curved springs mounted on suitable supports B B. The springs are adapted to slip on said supports for the purpose of extension, and to this end the respective parts are provided with connecting-lugs a. a and Z) Z), which serve as guides and holders for said parts, the supports B B passing through the clasps a a, and the springs A A through the clasps b b. The springs are made with a normal curvature their whole length, as indicated by the partial view of one of them in Fig. 4. The effect of this is not only to throw their upper extremities forward to a proper position with respect to the head, when extended, as shown in Fig. 1, but to cause them to bind in the clasps b b when so thrown forward, and thus automatically lock themselves in any desired position. When it is desired to slip them in or out, they are bent backwardly until about straight.

The supports B B are connected at the up per and lower ends by hinged arms 0 O and D D, respectively. These are made to lock in the extended position shown in Fig. 2, being made to open a little past a right line and provided with stop-lugs e e. The upper ends of the supports are provided with hooks E E, adapted to catch on the top of the seat or chair back. They should be spring-hooks, so as to hold snugly on any seat to which they may be commonly applied. Normally they extend backwardly, as indicated in all the figures; but for the purpose of making the device more compact when closed, we pivot these hooks in lugs c c, and thus admit of their being turned around half-way, so.

that the loop of the hook may lie on thesame side as the spring, as shown by the hook at the left in Fig. 4:.

The upper ends of the springs are provided with suitable holes, and in these are attached by hooks d d the head-rest strap or cushion F. The direct flexibility and torsion of the springs secures a natural and comfortable support for the head, which is particularly desirable in the case of railway travel, where the backs of the seats are ordinarily too low for this purpose. The compact form of the device when closed at the same time renders it convenient to carry, as it may be placed and occupy but little room in a valise.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a head-rest, the combination, with a frame composed of two vertical supports having hooks at their upper ends to engage with the top of the seat-back, and two pairs of hinged arms connecting said supports at or near the upper and lower ends, respectively, of two springs having a normal forward curvature throughout their length, a clasp attached to the lower end of each spring inclosing the supports, and a clasp near the upper end of each support inclosing the springs, said springs being mounted directly forward of the supports, so that the curvature of said springs isbrought into direct op position to the forward surface of the supports and serves to hold them at any point by friction, and a cushion or strap hung upon the upper and forwardly-projecting ends of the springs, substantially as and for the purpaotness when folded, substantially as set 10 pose set forth. forth.
