CHARLES S. ROGERS, OF KANSAS CITY, MISSOURI, ASSIGNOR OF ONE-THIRD TO IVINFIELD FREEMAN, OF SAME PLACE.

ADJUSTABLE HEAD-REST.

SPECIFICATION forming part of Letters Patent No. 426,069, dated April 22, 1890. Application filed January 3, 1 889. Renewed January 23, 1890. Serial No. 337,799- (No model.)

To all whom it may concern:

Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Adjustable Head-Rests, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates particularly to portaro ble head-rests, and has for its object to provide a head-rest that can readily be attached to the back of a car-seat, dentists, barber, or other chair, and can quickly and easily be adj usted to support the head of the user in many I 5 desired positions.

It consists in certain details of construction and arrangement of parts, as will more fully appear in the specification and be pointed out in the claims.

Referring to the drawings, in which similar letters and figures of reference indicate corresponding parts in all the figures, Figure 1 is a perspective view of my improved head-rest adapted to be applied to a barbers chair. Fig. 2 is a side elevation of my head-rest applied to the back of a barber-chair. Fig. 3 is an enlarged view of. the clamping device by means of which the rest is securely held in position.

Fig. 4 shows details of construction, which will 0 be more fully described farther on. Fig. 5 is a detail view of the clamping device used to secure the head rest to the back of car-seat. Fig. 6 shows a detail view of knuckle-joint, and Fig. 7 is a section view of same.

In constructing my invention I employ a pad A of any suitable shape, which is pivotally secured at either end between the uprightportions of the arm G. Extending downwardly from the middle of the arm G is a standard 3, which terminates in fiat circular plate J, said plate being pivoted to a corresponding circular plate B by means of the screw 13, as most clearly shown in Fig. '7. The plate B is 0011- nected to a similar circular plate B by the arm 5 or part (Z, the plate B being also pivoted to a circular plate f, similar in construction to f, said plate f being formed with a downwardlyprojecting cross piecc C, terminating at either end with the curved arms g, adapted to grip the top of the back, Pivoted to the lower side of the portion C is a clamping-arm D, which has formed 011 its rear side a screwthreaded lug a", carrying the screw D, which bears against the finger D and serves to press the arm D to the back of the chair.

Upon the outer faces of the plates B B, at about their middle portions, are formed the parallel apertured lugs or cars a a, between which are pivoted the spring-levers a a. At one end of the lever a is pivoted the pin or bolt 0, which passes --through the aperture 6 of the plate B or'B and engages with the cone-shaped holes 0, formed in the plate f or f. At the other end of the lever a, upon its underside, is attached the leaf-spring b, which serves to throw the pin 0 into engagement the moment the pressure is released.

By means of the plates B,B,f,andf, formed and connected as shown, and the spring-levers a a it is clear that the head-rest may be quickly adjusted to any desired angle.

To provide for the further adjustment of the head-rest, I attach the semicircular serrated plate E at one end of the pad A, which works in an opening formed in one of the upright portions of the arm G and is engaged by the cam-shaped turn-pawl F,by which the rest proper can be held at any desired angle.

It is obvious that the straps J J may be substituted for the clamps G D, and when so desired the arm G, which is cast integral with plate f, is formed with a ratchet-faced projection 2, which engages with a similar proj ection 1 on the clamp K, said projections 1 2 having the threaded apertures 7t 7a to receive the binding-screw k. By this arrangement the pad and knuckle-joints can be entirely reversed in case the causeat is turned over without removing the head-rest from said back, as shown in Fig. 5. Upon the under side of the pad A, I attach a pocket 0 for the reception of tickets.

The various parts of my invention which are substantial equivalents may be substituted for each other, as desired, without departing from the principles of my invention, and as the manner of operating my device is clear from the above description it needs no further description here.

By the term kinucklejoint it will be understood that I refer to each of two engaging plates or disks f B or f B and their adjunctive parts.

Having thus described my invention, what I claim is 1. The adjustable head-rest consisting of the head-support, its supporting frame or bracket, one having a cam-shaped pawl and the other a ratchet, a standard and seatback clamp or holder, each provided with a circularly-apertured disk or plate and arm (1, having a circular plate at each end thereof, and spring-pressed pawls carried thereon and engaging the apertured disks or plates, whereby the standard and seat-back clamp are connected and the head-rest may be adjusted and held in any desired position, substantially as described.

2. The adjustable head-rest consisting of the head-support, its supporting frame or bracket, one having a cam-shaped pawl and the other a ratchet, a standard and seat-back clamp or holder, each provided with a circularly apertured disk or plate and arm d, having a circular plate at each end thereof, and spring-pressed pawls carried thereon and engaging the apertured disks or plates, said seat-back clamp consisting of a cross-piece having downwardly-projecting arms and a clamping-arm pivoted to said cross-piece and having a screw-threaded lug carrying a screw, substantially as specified.

In testimony whereof I affiX my signature in presence of two witnesses.
