My present invention has reference to a 1 head rest forfus'e in eonheotion with barbers chairs and my object of the invention is the provision of a head rest for this purpose" which has a yieldable facing so that the same will readily comply to the shape of the head of the person resting thereagainst WlthOUt-il'lfi'ictiilg' inj ury thereto," which has a novel means for feeding a protective paper over the facin and iii e'aiis ior detaching soiled sheets of such pa13e'r,wl'iich ijsi swingabl'y adjusted to' adequately adapt; itself to the parts of the head of the person" resting therea'gainst, and I to likewise comply with the shape of. the

Figure 12' is a View substan a plan view of the coil"structio i disclosed by Figure12.

The head rest proper comprises two' 'side plates 1"1 whose outer edges are ciirved, whose ends may be dished inwardly and soak loped and whose outer edges" are also preferably arched. These plates 1 are'co'nne ct'ed together, at their rear edges throughthe medium ofa connecting strip 2 but obviously this strip may be detachably secured to the sides 1. The outer corners of thesides 1 are also connected through the medium of rods 8, which have reduced ends thatafford abutting shoulders for the side plates 1 and which are interiorly. threaded ior th'e reception of binding screws 4;. Obviously the reduced threaded ends of the rods?) may be eXtei-iorly threaded andinay be engaged by nuts which cont'actwi'th' the outer face of the sides 1;

p The numeral indicates a leather or like compressible strip. This strip provides the outer face of the headrest, and as-disclesed by the drawings he-r e. 4 A .c

The roundedor ourvedouteredg'es of the sides are preferably formed with equidistant:

has its en ds supported on spaced il h re preferably notched I y I tiallysiihilarto I -Figure 8, illustrating a slight modification.

and which afford anchor members for loops on the end convolutions of coil springs 8. The springs, of course, contact directly with the inner face of the leather or like compressiblefacing 5, and while normally hold ing the facing in one position, permit of the same conformingto and affording a yieldable rest for the head of the person reclining thereon.

The ends of the leather strip or facing are rounded upon themselves, stitched together and have passed through the said rounded portions, rod s 9, and'through the rounded or beaded edges of the strip 5, disposed over the rods there are, at spaced intervals, oppositely disposed hooks which are designed to engage with the end convolutions of coil springs 11. The springs 11 are equidistantly spaced and tension the fabric or compressible strip 5. The advantages of the construction as so far described will, it is thought, be understood and appreciated by those-skilled in the art to which the invention relates.

The sides 1 of the head rest, adjacent to the rear and to the lower portion thereof, have secured upon their inner faces the offset ends of spring discs 12. The discs 12 each has a central opening therethrough' for the reception of the flared or conical ends of trunnions 13 secured on the sides of a roll around which the paper 14, (that provides a protective facing for the head rest) is wound. The

spring influenced discs 12, however, may and are preferably designed to frlctlonally contact with the ends of a split tube 15, best shown in Figure 11 of the drawings, and within which tube the wound portion of the protective paper sheet is received, the edge of which paper, of course, passing between the lapping edges of the tube 15. The tube, at points adjacent to its center and opposite its lapping edges, is formed with lugs 16 16 which, as disclosed by the dotted line position of the human hand in Figure 11, permits of the tube being expanded for the arrangement of the paper roll therein or permits of the tube being handled so that the same can be arranged between the friction discs 12 or sustained in the head rest by contact with such friction discs.

' The paper from the'roll is, of course, directed around the lower corner of the head rest over the yieldable front thereof and is from thence directed along a longitudinally arranged cutter member or knife 17 that is preferably received in a cross sectional U-shaped housing 18 whose ends are secured to the sides of the head'rest. The paper is likewise directed over a compressible roller 19. This roller has a shaft 20 passing centrally there through, and is secured thereto. The shaft 20 is extended through bearing openings in the sides of the head rest. One end of the shaft 20 is provided with a knurled head 21 and spring material and will exert a tension to ward the roller 19 to insure a frictional engagement between the sheet and the roller.

By themeans as above described it will be noted that a rolled sheet of protective paper may be easily and quickly positioned in the head rest and may be positively directed thereover, and moved by the operation of the turning of the shaft 20 so that desired lengths may be severed therefrom by merely drawing the paper against the knife edge of the cutter element 17.

Either formed centrally onthe strip or plate 2 or centrally secured on a strip or plate which is screwed in or otherwise secured to the said plate 2, there is an outwardly directed lug 23 whose outer edge is rounded and'is toothed, as at 24. The flat lug 23 is received in the bifurcated end 25 of what I will term a rack member 26. An adjustable pivot 27 connects the lug 23 to the bifurcated end of the rack 26. From its bifurcated end the rack bar 26 is formed with a longitudinal socket 28. Passing centrally through his rack bar, and, of course, through the socket 28, there is a'rod 29. This rod has a pointed or beveled end to engage with the teeth 24 of the lug 23. The said end of the rod has also arranged theret-hrough a stop element which is engaged by one end of a coil spring 30 which is received in the socket and which contacts with the inner wall thereof to urge the rod to engage with the teeth 24. The rod has its outer end headed, as at 31, tocontact with the outer end of the rack bar 26. The said outer end of the rack bar is notched, as at 32, and the portion of the rod received in the notch is formed with a laterally extending lug 33 which contacts with the inner wall provided by the notch when the rod, (which in reality provides a spring influenced locking. dog), engages the teeth of the lug 23. The lateral part 33, when the rod is turned in the rack bar, is pulled outwardly therefrom and, when the rod is further turned, contacts with the outer end of the rack bar and holds the locking dog from engagement with the teeth of the lug 23. lVith an arrangement as just described it will be seen thatthe head rest may be swung to variousdesiredpositions on the rack bar, which is sustained in a suitable support to be hereinafter described, so that the head rest may adapt itself to the head of the person being operated on, regardless of-the angle which such person assumes in the barbers chair.

The rack bar 26 has its lower edge provided with transverse teeth 33, and its upper end I 5 fthe impndvemeht. "Thetop ef-the sgcket thenehe.

The notch 61- is'engaged by a finger operated spring latch 68 substantially similar tothat previously described. In each instance the latch members 55 and 68 are preferably formed from a single strand of spring wire connected and bent upon themselves to afford the active ends thereof with sufficient resiliency to freely enter the notches -of the supporting plates or arms.
