My invention relates to a head rest for barbers chairs and has for its principal ob jects the provision of a relatively simple and practical head restthat is mounted so that is has a wide range of adjustability in order that the head of the occupant of'the chair may be comfortably and conveniently sup-v ported; to provide a barbers chair head rest thatmay be easily and quickly manipulated when adjusted to different positions; and further, to provide a device of the character referred to that is inexpensive of manufactureand which will be very effective in performingits intended functions.
With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawings, in which Fig. 1 is a side elevational view of the upperportion of the back of a barbers chair and showingmy improved head rest applied thereto.

Fig. 13 is an elevational view of the upper portion of a barbers chair with the head rest removed as is required during hair-cutting operations and'with the head rest supporting posite side of disk member shifted into an-out-of-the-Way position.
Referring by numerals to the accompany ing drawings which illustrate a practical embodiment of my invention, 10 designates the back of a barbers chair to the upper rear portion of which is secured a plate or housing 11 that contains the usual spring held pawl that is utilized for locking a vertically adjustable ratchet plate 12 at different elevations and said spring-held pawl being released by meansv of a push button 13 that operates through the lower portion of plate 11. The parts just described are of standard construction and are found on practically all makes of barbers chairs.
In order that the vertically adjustable I ratchet bar 12 may serve as a support for my. improved head rest I provide on the upper end of said ratchet bar a disk 14 having a centrally arranged aperture 15' for the reception of-a pin or bolt 16 and journaled on saidpin or bolt and positioned immediately adjacent to one side of disk 14 is a disk 17 with the edge of which is formed integral an outwardly projecting block 18 through which is formed a square or noncircularaperture 19. j
Formed in the inner face of disk 17 is a series of apertures 20 that are adapted to receive the end of a latching pin 21, the latter being arranged for sliding movement through an aperture 22 that is formed through disk 14 and the end of this pin opposi'te the end that engages in the aperture 20 is provided with a head 23. Arranged on the pin 21 between the head 23 and a shoulder within aperture 22 is an expansive coil spring 24, the normal tendency of which is to move the pin 21 through aperture 22 in a direction away from the disk 17 Mounted on pin or bolt 16 and on the op- 14 from disk 17 is a latching disk 25 in the inner face of which is formed an arcuate recess 26, one end of which is considerably deeper than the other so as to form a pocket 27. Projecting outwardly from the edge of this disk 25 is an ear 28 that is adapted to be manually on gaged When the disk is rotated to eii'ect'the latching or unlatching operations.
The outer face of the head 23 of pin 21 occupies the arcuate recess 26 and when disk 25 is rotated so that the surface of the shallow portion of recess 26 bears against head 23, the pin 21 will be forced through disk 14-. so that the point of said pin will occupy one of the recesses 20 in plate 17 thereby locking the same against rotary movement.
ll hen disk is rotated so that the head 23 of the latching pin occupies the relatively deep pocket 27 at one end of the recess 2-6, the spring 2 1 that is associated with the latching pin moves the latter through disk 14; so that the pointof said pin is withdrawn from the recess 20 in which it has been positioned, thereby permitting the disk 17 and parts carried thereby to be freely rotated upon disk 14:.
Arranged to slide freely through aperture 19 in block 18 is a bar or shank 29, the up per end of which is secured to a cross bar 30 and projecting upwardly from the ends of this cross bar are the end plates 31 of the head rest, the upper "portions of said plates being connected by a transversely curved plate 32.
Screw-seated in block 18 and adapted to bear on shank 29 is a set screw 33, which when tightened very securely locks the shank to block 18.
The lower edge of a pad 34:, preferably formed of two layers of leather or fabric and an interposed layer of curled hair or padding, is suitably connected to the lower portions of side plates 31 just below the lower edge of plate 32 and said pad, when in position for use, overlies said curved plate 32 and with its edges overlying the upper edges of the sine plates 31 as illustrated in Fig. 12. The upper edge of this pad encloses a longitudinally disposed coil spring 35. the endof which are formed into loops 36 and tl'iese loops are adapted to engage pins 37 that are formed on the upper edges of side plates 31 just above the upper edge of the plate 32 (see Figs. 8 and 9).
A roll of paper 37 is carried by a spindle 38, one end of the latter bein provided with a. pintle 39 that engages in a bearing in one of the walls 31 and the opposite end of the spindle 33 is provided with a recess 40 that is adapted to receive the inner end of springpressed pin 41 that is arranged for operation in a. housing 42 that is carried by the opposite one of the walls 31. The outer end of pin 4-1 carries a disk 43 that may be engaged when the pin is withdrawn from the end of the spindle to permit the latter to be withdraw or replaced (see Fig. 11).
Secured to the underside of plate 32 is one end of a spring 44, the free end of which is adapted to engage the central portion of the roll of paper 37 that is carried by spindle 38, thereby producing the de ired degree of tension on said roll of paper while the same is being unwound.
The ends of feed roller 45 are journaled in plates 31 just below the upper end of curved plate 32 and the pintle or trunnion on one end of this feed roller extends through the corresponding end plate 31 and carries a small disk or hand wheel 4.6 that is adapted to be engaged by the thumb and finger when the feed roller is rotated.
Arranged below the feed roller 15 and bearing against the periphery thereof is a pressure roller t? and the pintles 48 on the ends thereof project through slots -14) that are formed in the end plates 31. 48 are en aged by the ends of springs 50 which latter are supported from the pintles of the feed roller a5 and said springs normally force the pressure roller with'yielding pressure against the feed roller (see Fig. 8).
The web of paper from roll 37 passes from said roll beneath the roll edge of pad'3 t, thence upwardly over the entire surface of said pad, thence downwardly between the feed and pressure rollers l5 and L7, and said web of paper then passes between a. pair of spaced plates 51 that extend between the end plates 31 just below the pressure roller 47. The lower edge of the outer one of these pair of plates provides a tearing edge against which the web of paper may be engaged when the used portion thereof is torn off.
My improved head rest as described may be adjusted vertically relative to the upper end of the back of the chair by raising or lowering the ratchet plate 12 in the plate or housing 11 and which ratchetplate is retained in the desired elevation by the springheld pawl that is controlled by push button 13. Block 18 which serves as a support for the shank 29 may be adjusted into different radial positions by proper manipulation of the latching disk 25 which controls the latching pin 21, the end of which latter is adapted to engage in any one of the recesses 20 in disk 17.
Thus the head rest pr *per that is supported by shank or bar 29 may be adjusted into various radial positions relative to the axis formed by the pin or bolt 16 and when the desired adjustment has been secured, the plate 17 carrying block 18, and which latter carries shank 29, may be secured in its adjusted position by rotating disk 25 so that the face of the shallow portion of recess 26 engages the head 23 of pin 21 and forces the latter into that one of the recesses 20 that coincides with the recess 22 that is 00- cupied by the latching pin.
Further adjustment of the head rest is obtained by moving the shank or bar 29 through block 18 and after said head rest has been thus adjusted, it may be locked by tightening the set screw 33. r
Thus the head rest has three separate adjustments which enables. the head supporting portion of the device to occupy practically The pintles any position within the scope or range of its adjustability and consequently affording comfort and convenience to the occupant of the chair.
The web of paper from the roll 17 extends over the pad 34 thereby providing a sanitary surface for the head of the occupant of the chair to rest upon and with every succeeding occupant of the chair, the feed roller may be manipulated to draw a fresh portion of the Web of paper onto the pad and the soiled or used portion of the paper that feeds downwardly beneath plates 51 may be read ily torn ofl by pulling said paper outwardly so that it engages against the lower edge of the outer one of said plates.
When the occupant of a chair is to be given a hair cut, said screw 33 is released to permit the bodily removal of the head rest and shank 29 and disk 17 and block 18 are now turned forward and downward so as to occupy an out-of-the-way position on top of the back of the chair as illustrated in Fig. 13.
lVhile I have illustrated and described my improved head rest as being especially designed for use on barbers chairs, it will be understood that the rest with very little if any modifications, may be advantageously used on dental and surgical chairs or in fact on any chair where a comfortable and convenient head rest is desired.
Thus it will be seen that I have provided a barbers chair head rest that is relatively simple in construction and which has a wide range of adjustability, thereby insuring a convenient and comfortable support for the head of the occupant of the chair.
It will be understood that minor changes in the size, form and construction of the various parts of my improved barbers chair head rest may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims. 7
I claim as my invention:
1. The combination with a barbers chair, of a-member mounted for vertical adjustment on the upper portion of the back of the chair, a disk carried by the upper end of said vertically adjustable member, a spring pressed pin extending through said disk, a member pivotally connected to said disk and provided in its inner face with a series of recesses that are adapted to receive the point of the spring pressed pin, a short shank projecting from said pivotally mounted member, a head rest adjustably carried by said shortshank, a manually operable disk pivotally mounted on the side of the first mentioned disk opposite from the side on which the shank carrying member is pivotally arranged, the inner face of which pivotally mounted disk is provided with a recess that receives the head of the spring pressed pin and the bottom of which recess is in the form of a cam having difierent elevations.
