BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 476,774, dated June 14, 1892.

Application tiled March 9, 1892. Serial No. 424,321. (No model.)

T all whom it may concern:

Be it known that I, GEORGE XV. ARCHER, of Rochester, in the county of Monroe 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 same, reference being had to the accompanying drawings, forming a part of this specilication, and to the reference-numerals marked thereon.

My present invention relates to that class of chairs especially adapted for barbers use, and has for its object to improve their construction, whereby an adjustment necessary to place the occupant in the most comfortable position may be readily accomplished by the operation of a single part, and also the chair may be raised and lowered to suit operators of various heights; and to these and other ends the invention consists in certain novelties of construction and combinations of parts, all as will be hereinafter fully described, and the novel features pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a longitudinal section of a chair, showing my invention applied thereto; Fig. 2, a plan view of the seat-frame; Fig. 3, a vertical section taken on the line marof Fig. 2. Fig. 4 is a sectional view taken on the line 1j y of Fig. 2. Figs. 5 and 6 are sectional views on the lines a h and e cl, respectively.

Similar reference-numerals in the several figures indicate similar parts.

The back 1, seat-frame 2, depending bars 3, constituting part of the forward frame supporting the foot-rest, and arms 1l are of the ordinary or any preferred construction, the back being pivoted to the frame at 5 and to the rear ends of the arms at 6, the forward ends of the arms being pivoted at 7 to the depending front bars 3, which latter are pivoted to the frame 2 at 8, the construction being such that when the back is tilted to the rear the depending arms 3, carrying the foot-rest, are elevated.

The base 9,011 which the chair is supported, is provided with suitable legs 10, and the connections between this base and the seat-frame and adjusting mechanism form the subjectmatter of my present invention.

Secured to the under side of the seat-frame 2 is a spider or frame composed of the side arms 1l, rearwardly-extending arm 12, and forwardly-extending arm 13, said arms being preferably formed integral with the central annular portion or ring 14E, provided on opposite sides with upwardly-projecting lugs 15 for steadyin g the operation of the locking device, as will be described, and at the rear with lugs 16 for steadying the movement of a longitudinally-sliding rack-bar 17, by which the adjustment of the chair is controlled. This bar 17 slides on the top of the spider and is prevented from lateral movement by the lugs 16 and also by depending lugs 1S, with which it is provided, engaging the rear arm 12, and its forward end isalso guided in its movements by a projection 19 on the spider, entering a groove 20 in its side. A link 21 is pivoted at one end to the forward portion of the rack-bar and at the other to the piece 50, connecting the depending bars 3, so that by the adj ustmentof theback the rack 17 is moved backward and forward and the adjustment of the chair will be accomplished.

Secured to the base 9, and preferably near its upper end, is a nut 22, in which operates the threaded standard 23, provided with an annular ange 24, to which is secured by rivets or otherwise a ring 25, provided with a series of perforations 26 near its periphery, and upon this ring the lower edge of the annular part 14 of the spider has its bearing, constituting a swiveled support for the chair, the parts being retained in operative connection by suitable bolts or screws 27 on the arms of the spider, which project beneath its edge, as shown, and prevent its upward. movement, though they do not interfere with its being rotated thereon.

While I prefer to make the iiange 24 and ring separate, it is obvious they could be constructed in one piece, if desired;

On the inner sides of the standard are provided two projections 28, having verticallyextending slots, and located with the standard is a vertically-movable rod 29, having a pin 30 cti-operating with the slots in the proj ections or standard, and to the upper end of this rod is connected a device for engaging the bar 17 and locking it, consisting ot' ayoke or casting 3l, provided with a central-aperture, through which the bar 17 passes, the

Y laterally-extending sides projecting between the lugs 15 of the spider and the depending arm 32 projecting downward and adapted to engage one of the series of holes 26 in the plate 25, said arm being slightly longer than the portion of the yoke engaging the rackbar 17. The connection between the rod 29 and the casting 31 is formed by extending' the rod through the lower portion of the casting and providing pins 33, engaging it on the upper and lower sides, as shown, so that the vertical movement of the rod will cause the lifting of the yoke 31; but the latter, which is laterally rigid with the chai r-seat, may turn independently of said rod. The lower end of the rod 29 is provided with a screw-thread oi' the same pitch as the thread in the nut 22 in the standard, and screwing upon itis a nut 34, pivoted on the end of the link 35, which in turn is pivotally supported on a foot-lever 36, pivoted to the chair-base and extending outwardin position to be con venientlyactuat ed by the operator. Aspring37 encircles the rod 29, engaging at its upper end a washer 38 beneath the lugs 28, and its lower end is supported upon a washer arranged above a pin 39, passing through the rod above the nut, said spring holding the rod and the locking-yoke moved downward in engagement with the rack-bar 17 and holding the projection 32 of the yoke in engagement with one of the perforations in the plate 25. In normal position the standard is held locked to the base by means ot` a set-screw 40, passing through the side of the nut 22 and engaging the standard, and the tilting of the chair-back and foot-rest can be accomplished by the operator pressing on the end of lever 36, and through the link, nut, and rod raising the yoke 3l a distance sufcient to release the rack 17, when by manipu' lating the back the desired adjustment can be secured, and if it is desired to rotate the chairseat on the standard a further upward movement of the yoke will disengage the projection 32 from the plate 25, when the chair-seat and spider may be rotated on the latter plate to the desired position, the yoke moving with them independently ot` the rod,'and upon the release of the treadle the parts will become locked in position again by means of the action of the spring.

Should it be desirable to change the elevation of the chair to suit operators of different heights, it is only necessary to loosen the setscrew 40, and the standard maybe rotated in the nut 22 in the base and the chair-seat elevated or depressed. As the rod 20 rotates with the standard it will be moved upward through the nut 3Jr without affecting the position of the lever 36, and the connection formed by this nut between the actuating-lever and the locking-yoke or equivalent device is very desirable, as it enables me to einploy a stationary releasing-lever connected with a vertically-movable standard in such manner that the latter can be adjusted without affecting the position or operation of the former. When the desired vertical adjustment of the standard is accomplished, it may be locked to the base again and the tilting and rotary movements of the chair governed by means of the foot-lever` as before described.

It is obvious that substantially the same mechanism as herein shown and described could be employed in chairs in which the front is not adjustable, but the back only, the latter being connected to the rack-bar 17, said rack or an equivalent movable portion being, considered broadly, a movable part governing the movement of the adjustable part of the chair.

While I prefer to employ all the adjustments herein described in my chair, it is obvious that the movable locking portion described as the yoke could be employed only to control the chair when moved on the standard or only when the back is adjusted, or both, as shown. Again, the same eXtensible connection between the lever and the part calle-d the yoke could well be employed in chairs having other adjustments-as, for instance, one in which the movement of a part corresponding in position only to the yoke would cause other adjustments or operations.

Instead of supporting the nut 34 on the lever, it is obvious that a screw could be connected to the lever and the nut formed on the rod 29.

Other similar modifications could readily be made withoutdeparting from the spirit of my invention. A
