BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 445,014, dated January 20, 1891..

Application filed February 8, 1890- Serizrl No. 339,681. (No model.) 7

such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvementin barbers chairs; and it consists in the combination and arrangement of parts hereinafter described and claimed.

The objects of my invention are to provide a means whereby the foot-support and front of the chair can be slightly tilted up for the purpose of permitting the chair to be freely revolved without changing the position of the base; to pivot the foot-support so that a person occupyingthe chair can adjust it into any desired position,and to provide a means whereby the back of the chair can be adj usted to any desired angle, according to the position the barber wishes the person in the chair to assume.

Figure 1 is a vertical longitudinal section of achair which embodies my invention. Fig.

2 is a side elevation of a foot-rest and its attachments. Fig. 3 is an inverted plan View of the entire chair. Fig. 4 is a detached perspective of the yoke upon which the chair is journaled.

A represents the legs, and 13 the body, of the chair.

The back 0 of the chair is pivoted between the two arms D at any suitable distance above its lower corners, so as to be adjusted into any angle desired. Recessed in the back of the chair are the two ratcheted segments E, between which is pivoted the lever F. Passing endwise through the lever is the spring-actuated catch G, which engages with ratchets E, and thus locks the hackin any desired position. In the outer end of the lever is placed a screw-nut H, through which the rod of the catch passes and which can be adjusted so as to give the catch a greater or less amount of movement, as may be desired. The ratchets upon the plates E are shaped so that when the back 0 is thrown forward the catch G will freely slip over them without being operated; but when it is attempted to throw the back backward the catch G engages the shoulders of the ratchets and will not slip over them, thus locking the back against any backward movement without first operating the catch, but allowing it to be moved forward without the necessity of operating the catch G. Pivoted to the lower edge of the lever F is a supporting rod or lever I, which is pivoted at its lower end to a plate or casting J, which is secured to thelower edge of the back of the chair-body B. This rod or lever I supports the whole weight which is brought to bear upon the back of the chair.

Extending across the bottom of the seat is the yoke L, which is provided with suitable journals at each of its ends, and which journals have their hearings in boxes N, which are secured to the chair-body. Projecting downwardly from the center of the yoke L is the pivot O, which is supported in'a socket formed in the top of the chair-base for this purpose, and upon this pivot the whole chair is turned without revolving the legs or changing their positionin any respect. Projecting rearward from the center of the yoke L and at right angles thereto is the slotted arm P, and secured to the under side of the chair B and extending down at each side of the said arm are the two bearings Q. A shaft R has its inner end passed through the slot in the arm P and journaled in the bearings Q, and is provided with a cam S, that engages the top and bottom walls 'of the said slot, whereby the chair is positively tilted in either direction. The outer end of the shaftR is journaled in a suitable box T, which is secured to the under side of the edge of the chair l3. To the outer end of this shaft R is attached a suitable handle U, by means of which the shaft R is made to revolve.

When the barber desires to turn the chair around upon its pivot, he has only to turn the shaft R by means of the handle U, when the cam'S upon the inner end of the shaft will engage the upper wall of the slot in the arm P, rocking the chair upon the yoke L, thus throwing the rear end of the chair down and reds ing the front of the chair, so that the feet under the foot-support will be raised clear of the floor, and thus permit the chair to be freely revolved upon the base A. Projecting from the bearing T are stops V, against which the handle U strikes when the front of the chair has been tilted up, and which stops limit the downward movement of the handle in either direction.

Secured to the front of the chair-seat is the foot-frame W, and to the outer ends of this frame is pivoted the frame X, upon the top of which is pivoted the foot-support Y. This frame X is pivoted so that the person occupy i'ng the chair can move the support nearer to or farther from the body of the chair, and thus make it accommodate the position in which he is sitting and to enable the footsnpport to be moved inwardly toward the chair-seat and thus take up less room in transportation. Pivoted upon the inner side of one'end of the frame X at any suitable point is the toothed segment Z, to the outer corner of which is pivoted the operating-lever A, the lower end of which is pivoted to the footframe \V, as shown. When the frame X is moved either toward or away from the chair- I body, the lever causes the segment to turn upon its pivot accordingly. Passing vertically down through a suitable guide 13 on the outer side of the frame W is an cndwise-moving catch 0, which has its lower end made to extend through a slot in the frame X, just below the edge of the toothed segment, and the upper edge of that portion a of the catch which passes through the slot engages with the segment for the purpose of locking the frame X in any position into which it may be adjusted. The upper end of the catch is slightly recessed, so as to correspond to the shape of the heel of the foot and thus enable the person sitting in the chair to place his foot upon the top of the catch and force it downwardly, so as to disengage its lower end from the segment and thus permit him to draw the frame X either nearer to or push it outward from him. Upon the upper end of the catch, above the guide B, is placed a spring D, one end of which is secured to the catch for moving the catch upward as soon as it is released. The moment the downward pressure of the foot is released from this catch the spring causes the catch to instantly snap into the segment.

Having thus described my invention, I claim i 1. The combination of the chair, the pivoted back, the recessed ratcheted segments placed in the back, the lever pivoted between the two ratchets, the spring-catch which engages With the ratchets, and the supportingrod which is pivoted to the lever at its upper end and to the seat at its lower end, substantially as shown.

2. The combination of the chair, the yoke journaled in its under side and provided with the pivot which extends into the base, and the slotted arm with the shaft provided with a cam upon its inner end and a handle upon its outer end, whereby the chair can be tilted on the yoke so as to raise the front of the chair, substantially as described.

3. The combination of the chair, the footframe secured to its front, the frame X, pivoted at its lower end to the said frame, the toothed segment Z, pivoted upon the frame X, a rod connected at one end to the said segment and at its opposite end to the foot-frame, and a catch which engages the segment for looking it against rotation, substantially as shown.

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

CHAS. FERST.
