BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 374,840, dated December 13, 1887.

Application filed March 10, 1887. Serial No. 230,342. (No model.)

.To all whom it may concern:

Be it known that I, THEODORE A. KooHs, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Barbers Chairs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a simple and effective device for adjustably locking thebaok andfoot-rest of a barbers chair on the desired inclination; and it consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanyin g drawings, Figure 1 represents a longitudinal vertical section of the barbers chair in its normal position or with the back and foot-rest in their vertical positions; Fig. 2, a similar section of the chair with the back and foot-rest adjusted to occupy a reclining position, and Fig. 3 a sectional plan 011 line 3 3 in Fig. 1,

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the seat-frame of the chair, consisting of the two sides,- each providing two legs, a and a, the upper side rail, b, and the lower side rail, 0, the two sides being connected by the transverse seat-supporting rails d d, by the lower front cross-rail, e, and the rear cross-plate, f. Between the front upper corners of the two sides is pivoted, at g, the pendent frame B, having at its lower end the foot-board O. The pivot-pins g for frame B form part of metal side pieces, D, of fancy shape-such as a swans neckwhich are secured against the upper edges of frame B and extend sufficiently upward for pivotally connecting therewith the front end of the armrest rails E, the rear ends of which rails are hinged to the side rails of the back F, being pivotally secured with their lower ends between the rear upper corners of the sides of seat-frame A. By this arrangement the armrests form the connecting-links between the back and foot-rest of the chair, whereby the swinging movement of either one will betransmitted to the other to assumea correspondingly angular position.

allow such rack-bar a limited vertically-slid ing movement, and coiled or leaf springs L, also secured against plate H, raise and hold such rack-bar K on its elevated position, and thereby its teeth in engagement with the teeth of the horizontally guided rack J. The treadle-bar M being secured with one end against the forward end of plate H on a pin, 1, it reaches rearward to the hind leg, at, of the chair, whence it extends downward to within ashort distance of the floor, with the rearwardly-protruding treadle m to the end thereof. At about its middle the horizontal portion of treadle-bar M is provided with an upwardly-projecting eye-lug, n, that is pivotally coupled with a central downwardly-projecting eye-lug, 0, of rack-bar K, in a manner that such treadle-bar M is suspended to such rackbar, and that both the rack-bar K and treadlebar M are thus yieldingly supported by springs L.

To the. hub of rack J is pivotally secured by a screw-stud a socket-casting, p, for coupling the ends of two rods, 0 and I, having eyed opposite ends that are pivotally coupled again with brackets q, rigidly secured against the opposite edges of the rear face of frame B, and for thus making the desired connections the rod 1? is placed on a diagonal position.

By stepping upon treadle m the barber will force downward the rack-bar K, thereby disengaging it from the teeth of rack J, when he can freely swing the back and therewith the foot-rest of thechair to the desired reclining position, wherebythe rack J will be pushed v or pulled to move longitudinally onits guidebar I to a corresponding position, and then by releasing the treadle m again the springs L, by their elastic force, will raise the rack-bar K again to engage its teeth with the teeth of rack J, thereby locking the back and foot-rest to retain their accorded reclining or upright position.

I am aware that barbers chairs have been known in which the back and foot-rest have been operated by the horizontal movements of a long rack-bar and held at any point by the vertical engagement of a pawl or projection acting upon the teeth or cogs of the rackbar, and I do not claim such.

What I claim is- 1. The combination, witha barhers chair having aback and foot-board pivotal] y secured to the frame of the chair and connected by the arm-rests for swingingsimultaneously, of rods connecting the foot-board with a short vertically fixed and horizontally-movable rack, a rack-bar extending nearly or quite the width of the chair-frame and vertically movable and engaging with the rack and coupled with a treadle, and springs yieldingly supporting such rack-bar and pedal, all substantially as set forth, to operate as specified.

2. In a barbers chair, the combination of the pivoted back and foot-rest connected to be moved and adjusted together, afixed guide- 25 rod, I, secured in the frame of the chair, a short sliding rack, J, movable thereon, and the connecting-rods O P,extending from rack J to foot-rest,with thelongitudinally-fixed but vertically-movable rack-bar K, springs for keep- 30 THEODORE A. KOCHS.
