lat the rear of the chair.
PATENT EEiCE.
FREDERIC M. SHEPARD, OF NEV YORK, N. Y.V
BARBERS CHAIR.
F5IZECIl-lGAlION` forming part of Letters Patent No. 349,063, dated September 14,1886.
Serial No. 186,387. (Noinodcl.)
To all whom it may concern,.- y
Be it known that I, FREDERIC M. SHEPARD, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Barbers Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention.
The seat slides in suitable ways in the framing,and has attached to its rear edge, by means of a link-joint, the back, which is hung, at a point a little above the height of the arms, on pins mounted in the side frames. On the under side of the seat is a ratchet, the teeth of which are engaged by a dog so set as to resist a forward movement of the seat. The dog is released or withdrawn by a downward pressure of the foot on a lever convenientlyplaced The dog oders but little resistance to the backward movement of the seat and consequent elevation of the back. This movement is effected by forcing the upper partof the back forward. The dog may or may not be withdrawn by the foot acting on the lever during thismovement. I provide rollers under the seat to reduce the friet-ion in its movement forward and backward.
By hinging the sliding seat to the back of the chair I can support the back of the sitter in all the required positions.
The chair is simple in construction and effective in its operation.
The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.
Figure 1 is a central vertical section. Fig. 2 is a correspon-ding view of a portion, the plane of sectionbeing taken just inside of the side frame; and'Fig. 3 is a section of a portion at right angles to the preceding ligures.
Similar letters of reference indica-te like parts' in all the figures.
A A are the side frames of the cha-ir.
B is the seat, sliding in the ways A A. On the edges of the under side of the seat are strips of metal, b b, which ride over the antifriction rollers c a' and take the wear. In the center of the under side of the seat is a ratchet, b', into which a spring-dog, R, engages in such manner as to resist any forward movement of the seat. The dog is held in engagement by a spring,1, encircling the rod r and acting with a pushingforce between an abutment, g, on the upper front cross-bar, G, and a collar under the dog It. r[he rod r is connected by a link, s, to a bell-crank lever, t, mounted on the lower front cross-bar, H. A long link, u, reaches backward to one end of a bent lever, o, turning on a center lixed to the lower back cross-bar, I. The 4outer end of the lever v is roughened to form a treadle, V.
The back C of the chair is hung on centers per part of the back of the chair rearward, and
through the action of the links D D throws the seat forward. As' soon as the back has reached the desiredinclination,the treadle V is released, and the dog engages one of the teeth farther back on the ratchet, and prevents any further niovementin this direction.
To elevate the back and place the sitter in a more upright position it is only necessary to push forward on the upper part of the back until the desired position is attained. The dog oders no resistance during this movement, excepting that due to the action of the spring r', and clicks idly as the teeth of the ratchet pass it. This clicking may be avoided by depressing the treadle, thus drawing the dog out of Contact, releasing it again when the back is sufficiently elevated.
It will be understood that the chair may be upholstered and ornamented in any suitable or ordinary manner. To avoid confusion in the drawings I have omitted to show such upholstering.
I claim as my invention- In a barbers chair, the tilting back C, pivoted to the side fra-mes, A A, at the point c, the inclined seat B, sliding in ways A A in said side frames, the links D, connecting the IOO back and seat, and locking mechanism een- E In testimony whereof I have hereunto set sisbing of the rack 1)',1oeated eentrallyand 1onniy hand in the presence of two subscribing gitudinnlly in said sent, dog R, rod r, spring witnesses.
