u BARBERS CHAIR.
SPECIFICATION forming part of Letters Patent No. 410,296, dated September 3, 1889. Application filed April 13, 1889. Serial No. 307,111. (No model.)
To alt whom it may concern:
Be 1t known that I, HANS A. SOHNEEKLOTH,
citizen of the United States, have invented certain new and useful Improvements in Barbers Chairs, of which the following is a specification. y I
This invention relates to improvements in barbers chairs, by which the inclination of the chair on the supporting-frame can be-quickly and effectively adjusted according to the position to be imparted to the body occupying the chair and to the headrest; and the invention consists of a barbers chair, the seat of which is hinged to the supporting-frame and connected at the front end by a pendent rod with a clamping device that is operated by a fulcrumed foot-lever and connected by a rod with said clamping device, the clamping de vice being constructed of two cam-levers pivoted to lugs of a cheek-piece, intermediate pivot-links between said cam-levers and the connecting-rod, and a spiral spring applied to the cheek-piece and the connecting-rod, by which spring the cam-levers are applied to the pendent rod Whenever the pressure on the foot-lever is released.
In the accompanying drawings, Figure represents a side'elevation, partly in section, of my improved barber-chair. Fig. 2 is a vertical longitudinal section of the same, drawn on a larger scale, showing the clamping device. applied to the connecting-rod of the seat; and Fig. 3 is a detail of the clamp for the headrest. 7
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents the supporting-frame and B the seat of my improved barbers chair. The seat 13 is provided with an inclined back O,which is provided with an adjustable head-piece C of any approved construction. The frame of the seat B is hinged to the supporting-frame A of the chair, and the front of the seat-frame is connected by a slightly-curved pendent rod D with a clamping device E, which is fixed on the front cross-brace E of the supportingframe A. The clamping device E is operated by a foot-lever F, which is fulcrumed to a cross-piece f at the rear part of the supporting-frame A, and the lever F is connected at its 4 upper end by a'connect-ing-rod F with the clamping device E. The clamping device E consists of the cheek e, having bent-up lugs e, to which are pivoted cam-levers E the cocentric portions of which extend in opposite directions, so as to engage the pendent rodD at two points, while the opposite ends of the cam-levers are connected by pivot-links c with the connecting-rod F A strong spiral spring 9 also connects one lug c of the cheek-piece c with the end of the connecting-rod F, said spring applying the eccentric portions of the cam-levers to the pendent rod D whenever the pressure on the foot-lever F is relaxed. The lower end of the lever F is provided with a foot-plate t, by which the clamping device is operated whenever the seat of the chair is to be adjusted. By pressing on the foot-plate t the connecting-rod F is moved against the tension of the spring g, and by means of the pi vot-links 6 moves the cam-levers away from the rod D, so that the cam-levers release the same and permit the free adjustment of the chair on its pivots at any desired inclination to the snpportingframe A. As soon as the proper inclination has been given to the seat the pressure on the foot-lever is released and the cam-levers returned by the action of the spring 9 into engagement with the rod D, so as to hold the same in position and prevent any change of position in the seat either in downward or upward direction, as the camlevers prevent any shifting of the rod D. The clamping device E is easily and conveniently operated by the foot of the attendant and permits the quick and reliable adjustment of the seat-frame and the rigid locking of the same after the seat has been properly adjusted.
A cam-lever M is pivoted at its upper end to jaws N on the back of the chair, and a spring R, acting on the free endof said lever M, keeps the cam end of the same in engagement with sliding rod 0 of the head-rest,thus locking 95 said head-rest in place. By pressing the lower end of the lever M toward the back of the chair the rod 0' is released and can be adj usted, and is automatically locked in place by the releasing-of the'lever M.
Having thus described my invention, I claim foot-lever, and a spiral spring secured to the lug of the cheek and the front end of the connecting-rod, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
