3 Claims.

This invention relates to barbers chairs. and those intended for similar purposes and in which a headrest is employed.

In using such chairs the headrest is required to support a customer comfortably while the barber is shaving him. If the next customer wishes to have a hair cut the headrest must be removed, since otherwise it would be in the barbers way. Usually the headrest is removably supported in the back of the chair, and if it is going to be in the way the barber simply removes it bodily and lays it on a convenient shelf.

The present invention aims to improve chairs or this general type with a view especially to making them more convenient for the barber to use and providing more sanitary conditions for the customer.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

In the drawings,

Fig. 5 is a vertical, sectional view approximately on the line 5-5, Fig. 4, but showing the frame upholstered; and

Fig. 6 is a perspective view of a barber's chair equipped with apparatus embodying this invention.

Referring first to Fig. 6, a barbers chair of a conventional form is there shown in dotted lines but equipped with aback 2 constructed in accordance with the invention. This back is suitably upholstered and the frame for it is best shown at 3 in Figs. 1, 4 and 5.

According to the present invention the back structure of this chair is equipped with a headrest so supported that it may be moved either into an extended or operative position, as shown at 4 in Fig. 6, or into a retracted and concealed position inside the structure of the chair back. Mechanism also is provided which may be manually actuated for moving the headrest from either of said positions to the other. As best shown in Figs. 1 and 2, the headrest 4 includes a skeleton or frame, indicated in general at 5, and

vided with grooved edges running on spaced guide bars 40-40, Fig. 1. Secured to a frame member a are two, tubes l6-l6 through which the rods ll slide, the tubes guiding these rods for vertical movement. Thus the entire supporting structure for the headrest is guided for up and 25 downmotion in a fixed path in the frame. In the particular arrangement shown the rods l l-l I are secured together at their lower ends by a crossplate 4, Figs. 1 and 4, and the lower end of the bar I4 is secured to a cross-bar l4, and the 30 latter is fastened to the part H4 by two braces HI, Fig. 4. Preferably the upper end of the slide |5| is steadied by a. wire brace 31 somewhat U-shaped in form, being secured to the crosspiece H4.

There is provided an opening in the member 8 through which the part I 2 has a sliding movement so that it can project somewhat beyond the front face of the member 8 when the headrest is 40 in the recess, as shown in Fig. 5.

For the purpose of raising and lowering the headrest a pinion I1 is arranged to mesh with the rack l5 and is mounted on a horizontal shaft l8 which is supported in bushings or bearings carried by the frame member 3. One end of this 45 shaft projects through the upholstery, as shown in Fig. 6, and has a crank 20 secured to it by means of which the mechanism may be actuated. Thus by rotating the shaft IS in one di- 50 rection or the other, the headrest may be raised or lowered.

In addition to this movement, however, it is also necessary to move the headrest forward after it has been raised out of its socketor recess 55 This entire structure is 10 the lower ends of this brace 35 rest is projected which are located in slots formed in the headrest frame member 8. It will also be observed that the shaft l8 extends through the guide tubes [6 and through cam-shaped slots 22-22 formed in the rods "-4 I. These slots are so shaped that during the first part of the lifting movement of the headrest produced by rotation of the shaft IS, the parts simply rise fromthelr positions shown in Fig. 4, the headrest coming through the aperture 23 in the frame. During this period the rods ll slide in the guides 16 and on the shaft l8, but when the upper ends of the spirally curved portions of the slots strike the shaft, both rods begin to turn in such directions as to swing the arms l0-l0 forwardly and this movement continues until the arms arrive in the positions shown in Figs. 1 and 2. At this time the headforward into its correct relationship to the main body of the back 2, as shown in Fig. 6. Further rotation suits in raising the headrest somewhat further, the shaft l8 at this time riding in the lower straight portions of the cam slots 22-22 which may be seen in Fig. 4. This latter rising movement of the headrest is desirable in order to adjust it to the heights of diflerent individuals. Also, in order to lock it in the desired position of adjustment, the shaft I8 is mounted to slide axially in the frame 3 and a collar 2i, Figs. 1 and 4, is secured to it. A pin 25 fixed in this collar projects away from the handle 20 and is adapted to enter any one of several holes formed in the adjacent fiat face of a bracket 26 which is secured to the frame 3, as best shown in Fig. 1. A coiled spring 21 encircling the shaft l8 tends to hold the pin 25 seated in one of these holes. 06nsequently, to the desired height and then lock it in that position simply by rocking the crank 20 slightly until the pin and is forced into it by the spring. 21. Also, by pulling on the handle 20 he may withdraw the pin from the hole and change the adjustment or lower the headrest into its inoperative position.

It will be evident from the foregoing that during the first few reverse revolutions of the shaft l8 to lower the headrest, the only movement of the latter is that in a downward direction. As soon, however, as the upper ends of the spiral portions of the cam slots 22-22'strike the shaft i8, the rods li--l l begin to turn to swing the arms ill-l0 inwardly toward each other as shown in Fig. 4, and this movement continues until the headrest has been moved backwardly into line-with its supporting and operating instrumentalities. Thereafter a further rotation of the shaft it lowers the headrest into the space in the back structure 2. a

In order to close the upper end of the recess or chamber into which the headrest disappears, a cover 28, best shown in Figs. 1, 2 and 5, is pivoted at its rearward edge on the frame 3, and is acted upon by a leaf spring in a direction tending to hold it constantly closed, as shown in Fig. 5. When the headrest rises it strikes the cover and opens it, as shown in Fig. 2, and it is held open by its contact with the parts II and I. As the headrest disappears, however, the cover follows it and finally comes ,to rest on shoulders provided in the upper margin of the aperture 23.

Similarly, it is desirable to close said aperture when the headrest is in its operative position in of the shaft l8 rethe operator may adjust the headrest 25 registers with one of the holes order to prevent, so far as possible, the entrance of dust into the headrest chamber. For this purpose another cover 30, Fig. 5, is hinged at the forward edge of the aperture 23 and is acted upon by a spring tending to hold it closed. When the g headrest moves downwardly it opens this cover, as shown in Fig. 5, but when it is raised out of the chamber in the chair back the cover automatically rises to its operative position, as shown in Fig. 1. Its free edge is notched, also as shown 10 in said figure, to accommodate the parts Ii and i4.

The head supporting surface of the rest 4 should be covered with paper while in use, and I- prefer, therefore, 1, 3 and 5, in the structure of the headrest and under or behind the upholstery material. It can be supported on pins mounted in short leaf springs or on one such member, as indicated at 33 in Fig. l, at roll projecting through a slot 34 in the other side member 6. This web of paper can be drawn around under the edge of the upholstery, over the front face of it, and back over the upper edge of the upholstery and between the plate 1 and a to spring actuated retaining member 35 which clamps the web yieldingly against the lower surface of the plate and thus holds it in its operative position on the headrest. This part 35 consists simply of a U-shaped wire or rod, the ends of which are bent,outward1y and extend through holes in the plates 8-'-8,'these bent ends forming pivots on which the device may swing. Before the barber shaves the next customer he draws the entire length of paper previously exposed through 6 adapted to give off germicidal fumes or vapors. 65

These thus will'be dispersed throughout the recess or chamber in which the headrest is located when in its inoperative position, and they will maintain the parts thereof in a sanitary condition. By mounting the receptacle on when the headrest is moved to the upper limit of its stroke into a position immediately under the aperture 23 where the supply of disinfectant material may conveniently be replenished.

The invention thus provides abarbers' chair 55 which is very convenient for him to use, and in which the headrest and the paper covering for it are protected from contamination. Essentially the same construction is adapted for other uses as, for example, by dentists.

While I have herein shown and described a preferred embodiment of my invention, it will be understood that the invention may be embodied in other forms without departing from the spirit or scope thereof.

Having thus described my invention, what I desire to claim as new is:
