ADJUSTABLE HEADREST.

' Application filed June 17, 1922. Serial No. 569,087.

To all whom it may concern:

, Be it known that I, GEORGE W. SPAHR, a citizen of the United States, residing at Mechanicsburg, in the county of Cumber- 5 land and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Headrests; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains vto make and use the same.

This invention relates to adjustable head rests as used by barbers and has for its obect to provide an adjustable head rest which can be manipulated by one hand. In devices as heretofore constructed,'both hands have been necessary 'to obtain angular adjustment of the head rest on the post on the back of the barbers chair. The present invention provides a device which permits the head rest to be tilted or adjusted by one hand. i

The novel features of the invention'will appear from the detailed description taken in connection with the accompanying drawings forming part of this specification.

Figure 1 is a rear elevation of a head rest and support showing the application of the invention;

Fig. 2 is a side elevation of the device shown in Fig. 1, a fragment being in section, and

Fig. 3 is a section on line 3-3 of Fig. 1.

In the drawings, 10 designates a bar or post which forms part of the equipment of a barbers chair and 11 a socket which is capped over said post, this socket being releasably secured to the post by any suitable means as indicated at 11.

Mounted on the socket 11 is a toothed secat 14. Mounted on the frame 13 of the head rest is a pair of lugs 15 within which 4' is mounted the shaft 16. Mounted on this shaft between the lugs is an adjustable tooth 17 this tooth being adapted for engagement with the teeth of the sector 12. The other end of the shaft is provided with a crank 18, this crank being disposed atone side of the frame 13 and projecting therebelow.

When the barber desires to adjust the head rest, it is merely necessary for him to apply turning pressure to the crank, thus elevating the tooth 17 and allowing the frame to tilt on its pivot 14: to the desired an le.

y locating the sector 12 intermediate the ends of the socket 11, the frame is effectually braced and by making the tooth 17 adjustable on the shaft 16, the crank of the latter can be set to anydesired angle. It will be noticed that the vertical part of the crank is in substantial alignment with one side of frame 13. This location of the crank makes for easy and convenient manipulation of thevoperating means.

What I claim is: I V

1. The combination with a support, a. toothed sector carried by said support, of a. head rest, a pivotal connection between said support and head rest, said head rest having a wall parallel to the plane of the axis of said connection, a shaft carried by said wall, a crank at one end of said shaft disposed beyond the side edge of said head rest, and a tooth secured to said shaft cooperatin' with said toothed sector and operable by sai shaft for adjusting the angularity of the 80 head rest.

2. The combination as in claim 1, said tooth being adjustable on said shaft.

In testimony whereof I aflix my si'gna- Y ture. v

GEORGE SPAHR.
