HEADREST Filed JamY 23. 192:3

INVENTOR 1710 -l 7 2 /7 @mam/add Patented Apr. 15, 1930 UNITED STATES FRED C. WARFIELD, OF JACKSON, MICHIGAN HEADREST Application filed January 23, 1952.8. Serial No. 248,770.

j The main object of this invention is to provide an improved head rest for the use of barbers, physicians, surgeons and undertakers by means of which the head may be supported in a wide range of positions, supporting the chin with the head ti ted forwardly or rearwardly as may be desired. A

A further object is to provide'a head rest having these advantages which is simple and economical in structure, is very easily adjusted and when adjusted is very secure.

Gbjects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

130 Fig. 1 is a front perspective view of my improved head rest in one extended position.

Fig. 2 is a side elevation of the head rest collapsed.

Fig. 3 is a longitudinal section on line 3-3 of Fig. 2. s

Fig. 4 is a transverse section on a line 4.-4 of Fig. 2.

Referring to the drawing my improved head rest comprises a base which in the embodiment illustrated is composed of side members 1, 1 and

end cross members

2, 2, these members being of angle cross section and arranged with the angles facing inwardly and o downwardly. The vertical arms of the side m members have longitudinal slots 3 therein.

I provide a pair of extensible supports of the lazy tong type which in the embodiment illustrated comprise a pair of bottom links 4, l pivotally connected to each other at 5. The lower ends of one pair of these links are pivoted to the side members of the base at 6 while the other ends are engaged by the bolt 7 which is arranged through the slots 3. The

`4.5 bolt is provided with a thumb nut 8 so that both of these links are clamped to the frame by one adjustment of the nut.

The coiled springs 9 are provided for lifting or extending the head rest and are con- @il nected at one end to the frame by the studs 10, their other ends being connected to the bolts 7 Y Top links 11 are connected by the Vpivots 12 to the upperjends of the links 4. The upper ends of the links 11 are pivotally connected by means of the thumb screws 13 which are threaded into laterally extending bosses 14 on the head rest 15. This head rest is conformed to receive a head, being of general oval shape, and is provided with a neck engaging cross piece 16 at its front. The side members of the head rest project above the cross piece 16 at 17, thus more eiiiciently positioning the head.

This arrangement makes it practical to tilt the head in a variety of positionsthe extensible supports supporting it in the desired elevation. If it is desired to lift the chin the head rest may be tilted to accomplish this.

My improved head rest is adapted for the use of barbers in shaving people who are ill as it is capable of adjustment to effectivelysupport the head for this purpose. It is also desirable for use by physicians, surgeons and undertakers. t
