UNITE SETH WHEELER, OF CASTLETON, NEW YORK.

HEAD-BEST FOR CHAIRS.

To all whom it may concern:

Be it known that I, SETH WVHEELER, a citizen'of the United States of America, and a resident of Castleton, in the county of Rensselaer, State of New York, have invented certain new and useful Improvements in Head-Rests for Chairs, of which the follow? ing is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in head rests for chairs, and particularly to that class of head rests adapted for barber and dental chairs.

My invention consists in a device having means for supporting a feed roller at one end thereof and a take-up roller at the other end,

whereby a web may be paid off the feed roller and taken up on the take-up roller, the portion of the web between such rollers constituting a surface upon which the head may rest. By this means a fresh surface may be constantly presented, thus insuring cleanliness and proper sanitary conditions, the web being composed of paper, fabric such as cloth or the like, or any other material which may be suitable for this purpose. And my invention consists in many novel details of construction and combination of parts as will hereinafter be more fully pointed out.

The main object of my invention, as will be well understood, is to constantly provide a clean surface asa rest for the head for each person using the device, and, in carrying out the details of my invention, I have particularly in mind to provide for the ready removal and replacement of the rolls constituting both the feed and take-u means.

My invention includes a nove form of roll, which is preferably provided with a supporting roller secured to each end of the web comprised therein, each roller provided at one end with a bearim portion and a turning means, and adapted at their opposite ends to receive the shanks of pintles which are rotarily mounted in the device.

In order that my invention may be fully understood, I will now proceed to describe an embodiment thereof, having reference to the accompanying drawings illustrating same and Wlll then point out the novel features in claims.

In the drawings: Figure 1 is a view in front elevation of a head rest embodying my invention, the post thereof being partly broken away in order to save space. Fig. 2 is a=bot- Specification of Letters Patent.

tom view of the device With the 0st broken away. Fig. 3 is an end view 0 the same. Fig. 4 is a detail sectional view of a portion of one of the rolls including the su porting roller, its turning knob, and materia carried thereby. Fig. 5 is a detail view of one of the rear brackets, with pintle carried thereby. Fig. 6 is a detail view on a reduced scale of a modified form of bracket employed.

The supporting elements of the head rest as a whole comprise a post 6, a frame 7, and a bridge piece 8 secured to the outer ends of arms 9 included in the said frame 7, the bridge piece 8 being preferably composed of a more or less flexible material such as a heavy piece of sole leather, the arms 9 of the frame itself having also more or less spring, so that the said bridge piece will form a yielding member upon which the head may rest.

The outer ends of the arms 9 are bent around as at 10 to form supporting means for brackets 11, which are pivotally connected therewith at such point. There are two such brackets 11 in the particular construction herein shown for each arm 9 of the frame, that is, four such brackets in all. Each arm consists of a pivotal portion 12 mounted in the part 10 of the arm, an extension 13 disposed at right angles to the part 12, and arranged to bear against the under side of the arm 9, a loop 1 1 also arranged at right angles to the part 12, but extending upon the opposite side of the part 10 of the arm 9, so that it ,will clear the said frame 7, as will be readily understood by reference to Figs. 2 and 3 of the drawings, a bearing ortion 15 arranged to receive and support t e ends of the rollers, as will be presently described, a shank 16 extending downwardly from said bearing portion 15, and a part 17 turned inward from said shank substantially parallel with the portion 12, the said part 17 adapted to be sprung over the upper surface of the frame to hold the bracket in position. The relationship of the part 13 to the rest of the bracket will be such that the whole bracket will have to be slightly sprungin order to allow the part 17 to be snapped into position. To make this clear, the bracket must not only be sprung outward so as to ermit the inner end of the part 17 to clear t e outer face of the frame 7, but the part 13, opposing movement froma position such as, say, the position of the dotted line in Fig. 1 to a osition indicated by the full lines in suc figures, the

I bracket must be also sprung in the direction of the arrow. The shape of the bracket with the loop 14 and bearingportion 15 will readily permit springing of this kind, and the result, when the parts are in their position such as is shown in Fig. 1, will be to hold the parts securely in position and to prevent any accidental displacement thereof. The brackets at each end of the frame piece 7 are preferably made as separate members, as is shown in Fig. 2 of the drawings, but a pair of such brackets may be connected together as by a connecting piece 18, if desired, as is shown in detail Fig. 6. In such case the pair of brackets at each end would conveniently be made of a single piece of wire bent to the specified. shape. v

Rollers are arranged to be supported by the said brackets, one at each end of the head rest; one of such rollers constitutinga feed roller and the other a take-up roller. For the pur oses of-this description we will term the rol or at the right hand end of the head rest, as shown in Fig. 1, the feed roller 19, and the roller at the left hand end of said figure the take-up roller 20. A web of material 21. is mounted upon the roller 19 to form the feed roll, said web passing over the bridge piece 9 on to the take-up roller 20,where it will be taken up as used. Preferably both the feed and the take-up rollers are secured to the web, one at each end thereof, each roll as supplied being thus complete in itself.

The rollers 19 and 20 project beyond the edges of the web at one side thereof as is clearly shown in Figs. 2, 3 and 4, the ends of the rollers forming trunnions by which they may be supported at that end. These trunnions are received within the bearing portions 15 of the brackets 11 and are adapted to rotate freely therein. The rollers may be of any form and material. So far I have found it convenient to construct them of paper in the form of hollow tubes, as is shown 1n Fig. 4 and I have provided knobs 23, having shanks 24 received within the hollow tubes at the ends at which they project beyond the web, said knobs being secured firmly to the tubes whereby they may be employed for turning purposes. The opposite ends of the tubes are adapted to receive the shanks 25 of pintles 22, said pintles constituting trunnions for the rear ends of the rolls and provided with portions adapted to be received in the bearing portion 15 of the rear brackets 11. The rear brackets 11 preferably differ slightly from the front brackets in that the loop or bearing portion 15 thereof is slightly pinched together as is shown in detail Fig. 5, (this figure showing one of the rear brackets with a pintle therein,) so as to prevent the pintles 22 from being accidentally removed there from. In other words, the pintles 22 form bearing trunnions which are permanently carried by the rear brackets 11, tubular portions of the rollers being slipped on to shanks thereof and away therefrom as the rolls are inserted into place or removed, the trunnion members for the forward brackets being the roller ends themselves, which engage the I bearing elements 15 of the brackets 11, as above (lGSClllfltBLl, and as clearly shown in the drawings.

To remove the rollers from their positions it will then be necessary to swing the forward brackets clear of their engagement by the portions 17 with the frame 7 and to slip the trunnion portions of the rollers free from the bearing portion of the forward brackets 11. The rear ends of the rollers may now be withdrawn from engagement with the shanks 25 of the pintle pin 22, the rear brackets 11 being swung clear or not, as will be found most convenient. I/Vhile to insert a new roller it will only be necessary to reverse the foregoing operation, finally readjusting the brackets to secure the rollers against accidental removal or displacement.

When first employing the device, the feed roller with the roll of material thereon may be inserted in one of the pairs of brackets while the empty roller for take-up purposes will be inserted in the other, the web being carried from the bridge piece so as to extend from one said roller to the other. As the web is used the take-up roller may be turned by means of the knob 23 thereof, which will take up the soiled portions of the web and unwind the fresh portion from the feed roll at the other end thereof. When the entire web has been rolled up upon the take-up roll 20, said take-up roll with the soiled web thereon together with the empty feed roll at the other end, may be removed and a fresh roll employed to replace it.

I have provided spring members 26 secured at one end to the said frame 7, and at the other end bearing upon the web contained on the rollers 19 and 20, said spring members forming a friction drag therefor, so

as to prevent the rollers from accidental turning, and the web thereon from becoming unrolled, except when it is intended that it shall do so by a turning movement applied to the knob or knobs 23.
