IMPROVEMENT IN BARB ERS CHAIRS.
Specification forming part of Letters Patent No. 165,232, dated July 6, 1875; application filed April 24, 1875. 7
To all whom it may concern:
' Be it known that I, WILLIAM HOEHN, of the city, county, and State of New York, have invented a new and Improved Barbers Chair, of which the following is a specification:
The accompanying drawingrepresents a side elevation, partly in section, of my improved The object of my invention is to furnish to barbers an improved chair whose back may be quickly adjusted to different heights without the least noise, effort, or annoyance.
The invention consists of a barbers chair, the back of which is adjusted by a screw-bolt ingnut, secured to a pivoted guide socket or tube of the seat of the chair.
In the drawing, A represents the seat, and B the back, of a barbers chair. The back is pivoted in the customary manner to the upper ends of the front legs, and adjusted by means of a screw-bolt, O, that is pivoted to lugs at the central bottom part of the back B. Screwbolt 0 is provided with a quick thread to produce on the turning of the operating nut the quick raising or lowering of the back. The smooth cylindrical end of screw-bolt 0 slides by the action of nut D, which is operated by a hand-Wheel, D, in a tubular socket or sleeve, E, that swings by trunnions or pivots a at its lower end in hook-shaped supports 1) of seat A for the purpose of adjusting itself readily to the changed position of the screwbolt on operating the nut. A locking-sleeve, F, is screwed tightly to the upper end of tubular guide-socket E, and bind by its grooved upper edge on a flange of nut D for retaining it, thereby connected to the guidesocket, but without obstructing the turning of the nut for adjusting the back.
By turning the hand-wheel D in either direction the back is quickly set as required Without the noise incident to the crank and gear-wheel devices, while the strong and sim- WILLIAM HOEHN. Witnesses:
