RECLlNlNG-CHAIR.

l u SPECIFICATION forming part of Letters Patent No. 242,733, dated June 7, 1881.

` Application tiled Februaryui. 1880.

`valid, dental, or barber chairs which are adapted to assume either an upright,reclining,

Ior horizontal position.

The object of the invention is to provide a reclining-chair in which provision is made for varying positions of the component parts thereof to enable the occupant to place him-` self in position from a sitting to a reculnbent position,-and which is designed to be used by invalids, by physicians as anv operating.

chair or lounge, and by dentists and barbers.

My improvement consists, iirst, in the combi-` nation, with perforated segments, of spring- -act'uated bolts and a lever Vhin ged to a pivoted block,V whereby such segments are locked and released by the action of the lever and bolts and clamped by the pivoted block, substantially as hereinafter set forth.

My improvementconsists,further, in ahin ged and pivoted cam-lever constructed with a lip, and adapted to be used in operating the slidingl lock-bolts, as a` guide for the segment, and as a brake to the segment, to preventthe chairback from falling too fast when the weight of the body is placed upon it.

My improvement consists, further, in combining with a hinged head-rest rods 0r tubes attached to the body of the chair for the purpose of raising the head-rest automatically as the back approaches a recumbent position.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure l is a perspective view of my improved char. Fig. 2 is a vertical section thereof. Fig. 3 is a horizontal section on the line 3 3, Fig. 2. Fig. 4t is a perspective view, showing mode of connecting head-rest rods. Fig. 5 is a side view, showing the parts adj usted so as to constitute a lounge.

The chair is constructed with a firm support, A, seat B, leg-rest C, foot-rail D, back port are side plates, G G, secured by bolts g g g g', which form pivots for the leg-rest frame H and back-frame I respectively.

. J J are segment-plates fnlcrumedl to the plates G G by studs j j, and K K are arms hinged to the upper ends of the segments by studs 7c k, and tothe back-frame I by studs 7c k. The segments are constructed with holes or depressions j j', and are provided at their lower ends with pintlesjzjg, which engage in recesses l l of and support slotted plates L L, hingedto the leg-rest frame H by means ot' studsff. y

M'M are theside frames of the head-rest,

-hinged to lugs or ears li i, and raised or lowered means of the set-screw O, thereby affording a means for regulating the angle at which the head-restV shall rest. The adjustment of the head-rest may be effected either before or after the chair-back is lowered. By simply loosening the screw O before the back is lowered the block 0 will, during the lowering of the back, slide down the lower tube, N, and thereby leave the head-rest in the same position it assumed while the chair-back was in its upright position. The descent of the lower rod or tube, N, may be stopped at any time by simply tightening the screw O, thus leaving the lower rod free to operate on the head-rest to push it forward or, by lowering the back while the lower rod is held rigid, and then loosening the screw O, the angle at which the head-rest shall remain can easily be regulated by pushing the upper rod and its attached block o along the lower rod. This arrangement of devices, it will be readily seen, admits of the easy regulation ofthe position of the head-rest g any desired inclination may readily be imparted to it at any time by simply loosening the screw O and sliding the block o along the lower tubea much more effective arrangement than where v the head-rest is supported upon jointed rods or bars without capability of being shortened or lengthened and rigidly clamped by screw. Where the head-reet is supported by one entire rod or by a series of jointed rods the nice and rigid adjustment of the head-rest obtainable by mtvdevice cannot be secured.

Beneathdie seat is a cross-piece, Q, on which is pivoted, by a bolt, q, a cross-bar, R, having hinged to each end bolts S S, which pass through suitable openings a a in the support A to permit them to engage with the holes or depressions j 7" in the segments J J The bolts are inserted by means of a spring, T, adapted to draw the cross-bar It so as to force the bolts outward. The bolts are limited in their outward movement by the cross-bar coming in Lcontact with a stop-pin, q. The bolts are retracted by means of a hinged and pivoted cam-lever, U, mounted on a plate, V, adapted to press in a push-rod, u, connected to one end of the cross-bar. The lever U has its cam portion u pivoted at a2, so as to permit it to turn and be pressed against the segment and thus form a brake thereto, while its lip a3 forms a guide to the segment. a4 is the hinge which permits the handle portion a5 to be pressed sidewise against the push-pin. On the opposite side of the support A is a plate,W, having lips w w, and adapted to form a guide and support for the locking-bolt S and segment J For forcing the bolts outward any kind of spring may be used of any suitable construction. It may be connected with cross bar, lever-rod, or lock-bolts, which would obtain the same results.

In Fig. 5 I represent, in dotted lines, the position ot' the cam-lever when it is desired t0 remove or apply thesegment.

When the back is in its lowest position it is supported by the arms which rest upon the side plates.

Having thus described my invention, the following is what I claim as new therein and desire to secure' by Letters Patent:

1. In combination with the perforated segments J J the spring-actuated bolts S S', and the lever U, hinged to thepivoted block, Whereby the segments are locked and released by the action of said hinged lever and bolts, and clamped by said pivoted block, as set forth.

2. In combination With the perforated segments and the hingedulever U, the pivoted block having cam and lipa2 a3, serving as a guide, clamp, and brake for the segments, as set forth.

3. In combination with the back, scat, arms, and foot-rest, the pivoted segments and the pivoted cam-lever, acting as a brake for said segments, as set forth.

4. The combination, with the frame A and tilting back I, of the head-rest F, hinged at its lower end to the lugs or ears i i, arm P, projecting from the rear of said head-rest, rods N N, block o, and set-screw O, one of said rods being pivoted at its upper end to said arm P, while its lower end is rigidly attached to the block o, the other rod being pivoted at one end to the base of the chair, While its other end passes through a hole in the block o, substantially as and for the purpose set forth.
