HEAD-REST.

i Application filed May 21, 1908. Serial No. 34,079. 1

To all whom it may concern:

Be it known that 1, Josnrrr C. BAHR, citi' zen of the United States, residing at St. Louis, State of Missourn'have invented oer tain new and useful Improvements in Head- Rests, of which the following is a full,.clear, and exact description, reference being had to the accompanying drawings, formin'g'a part hereof. v j I My invention has relation'to head-rests for barber-chairs (though notv necessarily limited to the latter) and it consists in the novel construction andarrangement of parts more fully set forth in the specification and pointed out in the claims;

In the drawings, Figure 1 is a side'elevar tion of a barber-chair showing my invention applied thereto; Fig. 2 is. a-front elevationof the rest in central osition; Fig. 3 is a'similar view showing tie rest rocked to one extreme, the front detachable fork-member of the rocker-frame being removed; Fig; 4 is' a similar view showing the rest rocked to the op osite eXtreme;'and Fig. 5 is a vertical e arged'cross section-onthe line 5. -5 of Fig. 2. V

The'object of my invention is to construct a head-rest for barber (dentist and similar) 1 chairs which will enable the barber to turn the head of the person in the chair, without disturbing the position of the head on the chair, the rest being so mounted that the desired tilting orrocking' motion may be imparted to the rest without moving the persons head. V

A further object is to construct a rest which will readily conform to any configuration of head su ported by the same, all as will be more ful y apparent from a detailed description of the invention which is as follows 1-- Y Referring to the drawings, C, represents a conventional barber-chair the back of which is provided with a longitudinal socket 1 to receive the bar or tongue 2 which carries the rest, as fully understood in the art. The upper end of the tongue 2 carries an anglepiece or bracket 8 whose vertical leg is provided at the ends of itsupper edge with A wings or abutments 4, l, for a purpose presently to appear. 7 V

The rest is composed of suitably curved longitudinally disposed straps 5, 5, terminating in handle- pieces 6, 6, one at each end of the rest, and one handle to each strap), the

Specification of Letters Patent.

middle portions of the straps being connected by a cross-piece 7 with which is formed a depending lug 8. Disposed on each side of the transverse center of the straps 5, 5, are pads 9, 9 made of upholstered material or they may be pneumatic or inflated sacks. Their adjacent ends are spaced a suitable distance apart so that the continuity between them is broken. By virtue of this construction, the ads or sections 9, 9, will conform themse ves to any outline of head resting against them, each section yielding in proportion to the pressure it may be subjected to by the weight of the head. A rolling of the head too is prevented, since the head is sup orted on either side of the center, instead at the center as would be the case were the sections of the rest made continuous or of one piece.

The lug 8 is provided with a hollow boss or spindle'lO carryin an anti-friction roller 11, said spindle being loosely received in a V- shaped slot 12 of the vertical leg of the bracket 3, the lug 8 bearing against the rear face of said bracket-leg (Fig. the opposite face of the leg is placed the de- 'tachable Against late 13 which is secured to the hollow spind.e by ascrew 14, the upper edge of the plate resting against the under surface of the cross-piece 7. Thus united, the parts 8 and 13 constitute a fol'k, whose members are united by the roller-spindle 1O freely playing in the V-shaped slot 12. By seizing one of the handles 6 and tilting or rocking the rest (from its central osition Fig- 2) in one direction, the spinde will run up one leg of the V-shaped slot, the edge of the crosspiece 7 being temporarily fulcrumed against its adjacent abutment 4 (Fig. 3), and when rocked'in the opposite direction, (Fig. 4) the spindle 1O traverses the opposite leg of the V-shaped slot, in which case the opposite abutment 4 serves as a fulcrum for the opposite edge of the cross-piece 7. The occupants head however is not disturbed as it lies in the head-rest, and a person may be shaved first on one side of the face, then on the other without necessitating the raising'of his head off the rest as is now generally done in the case of fixed rests. Where the rest occuples a central position (Fig. 2) the spindle 10 00- Without it being disturbed by any movement the occupant of the chair may make with his head, the rest only tilting or rocking when actuated by the barber by seizing the proper handle 6 and drivin the spindle 10 to the u per end of one of the legs of the \l-shaped s 0t. In this position the rest will remain until rocked back to either its central position, or its opposite tilted position. By simply removing the sere'o' 14, the plate 13 Will drop oli, and the rest may be detached altogether by .'itl'l{l1'8,.'-. ing the spindle from the slot 12.

It Will be noticed that the rest does not rock about a central transverse axis (r rich axis would be in the plane of section of the line 55 in Fig. 2) but it rocks in one direction about the axis disposed to one side of such central axis, and substantially alongone :i' the side edges of the cross-piece 7, and in the 0 posite direction about an axis disposed a ong the opposite edge of s at cross-piece; and while under those conditions the spindle 10 describes the arc of a circle, the slot 12 fords sullioient play to the spindle to accord it the privilege of such movement. In its tilted position, the rest is virtually locked against displacement, being supported at two bearing points, the one bearing; formed at the base of one of the inns or abutments 4, and the other by the spindle 1O resting at the upper end of one of the legs of the slot 12.

In tilting the rest, the edge oi the piece 7 about which it rocks to 2 either of the positions shown in Figs. 0 being located on either side of the transverse center of the rest, forms an of rotation for such rest, which axis is obviously dirposed to one side of the transverse center oi the rest. In other Words, tiie axis of lation of the rest does not corr the central being transverse axis of t is to one side thereof. It is this a Whicir as a center the rest revolves widen being tilted or rocked to cliang the position of the head of the occupant oi one chair.

Having described my invention, what I claim is 1. In combination with a fixed support, a head-rest, means for supporting and tilting a about the same about an axis disposed to one side of the transverse center of the rest, and. means disposed. below the fulcrum about Which the head-rest turns for guiding the same in its movements, substantially as set forth.

2. In combination with a fixed support, a headrest, means for supporting and tilting the same about an axis disposed to one side oi the transverse center of the rest, means for temporarily locking the same in its tilted position, and means dis-gposedv below the fulcrum about which the head-rest turns for guiding the same in its movementa, subst antially as set forth.

3. In combination with a liXed bracket having a substantially i -seaped slot, a beadrest having a central transverse member, :1. lug; depending" therefrom, a spindle on tit-e lug adapted to tra averse the legs ol the slot, lateral terminal wings on the rixed. bracket projecting; bcvond the top of the bracket, and allording support to the opposite edges of the transverse member, and means for retaining the spindle against \Jltldraval from the slot, substantially as set fortlt.

i. in combination with a lined. bracket raving a substantially if-shaped slot, a beadrest raving a basal centrally disposed transverse member, a lug depending tlmrelrom, a lrolloiv spindle projecting from one face of t e lug and traversing the slot, a detachable r secured to the free end of the spindle es ing tlie adjacent face of the bracket, terminal lateral wings projecting beyond 0 free edge of the bracket for ni- "aging the opposite edges of her for a central position "'jzer wing serving as a tulcrum-abr 'ient for a rocking movement; of the rest n n tilted. about one of tie edges of the transverse member, the parts opera tin; substantially as and for the purpose set for in testimony whereof I ali'ix my signature,

in presence of two Witnesses.
