Specification of Letters Patent.
Patented Nov. 21, 1911.
Application filed June 10, 1911. Serial No. 632,341.
To all whom it may concern:
Be it known that I, JOSEPH R. J oHN, a citizen of the United States of America, residing at Mount Clemens, in the county of Macomb and State of Michigan, have invented certain new and useful Improve-i ments in Barbers Head-Rests, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to head rests for barbers chairs and more especially to an arrangement thereof whereby provision. is made for renewing a shield or sanitary cover of paper or the likeand to a di'spo sition of the parts whereby the rest may be quickly manipulated and adjusted for use.
The invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.
Referring to the drawings, Figure 1 is a plan view of a head rest embodying features of the invention; Fig. 2 is a view in side elevation thereof with a dotted diagram showing the position assumed when the head rest is not in use; Fig. 3 is a view in section through the head rest wit-h a shield covering release; and Fig. 4 is a view in detail of a yoke frame.
As herein indicated a slide bar 1 of any preferred type adapted to be raised or lowered on the back of a chair and locked in suitable position by any preferred and suitable means carries a yoke 2 that is detachably secured as by a bolt and thumb nut 3 or the like. A frame having side arms 4 and 5 connected at their extremities by cross members 6 embraces the upper end. of the yoke on which it is pivoted by means of the cross rod 7. Preferably the meeting faces of the yoke and frame are serrated while a thumb nut 8 of any preferred type on the cross bar 7 clamps the parts in adjusted angular position.
A pad frame 9 that is preferably segmental in section has a pair of similarly disposed guides 10 of spring metal or the like which frictionally engage grooves in the outer faces of the frame arms 4 and 5 near the outer ends thereof so that the pad frame may be slid back and forth on the frame. A cushion 11 of suitable material covers the outer face of the pad frame between longitudinal slots 12 and 13 in the latter. The upper slot is covered by a spring finger or plate 14 Whose inner end is secured to the inner face of the pad frame by rivets l5, screws or the like.
A roll rod 16 is detachably mounted across the arms 4 carries a roll 17 of paper or the like whose end threaded through one of the slots, is drawn over the pad or cushion 11 and is passed through the upper slot under the spring arm 14, when the latter is allowed to move back from the yoke frame by sliding the pad frame up to the position indicated in Fig 3 so that the cross arms 6 do not hold the arm firmly against the pad frame. The latter has a marginal end plate 18 which extends beyond the spring finger 14 with a margin arranged as a cutting or tearing edge for severing the roll strip.
In operation the roll strip is threaded through when the pad frame is so positioned as to allow the spring arm to clear the frame and is then clamped by pushing the pad frame back to initial position. By manipulation of the thumb nut of the cross bar on which the mainframe is journaled the head rest may be swung on the stem or slide rod intoany position desired for the convenience of the operator. When the covering requires renewing the free end of the strip, is grasped and drawn through a sufiicient distance, first moving the pad frame up to release the spring finger, and is then torn off along the cutting or tearing edge of the frame after the latter is returned to the clamping position. By this arrangement a very simple and effective sanitary head rest is obtained which is convenient for use by the operator and which can be quickly adjusted and provided with renewed covering as desired. Another advantage is the disposition of the pad frame at such a distance from the pivot bolt so that a large roll may be inserted, the size of the latter not being restricted as it is in the usual constructions of head rests of this character.
Obviously, changes in the details of construction may be made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts, except as set forth in the appended claims.
What I claim is 1. A head rest for chairs comprising a supporting member, a yoke thereon, a frame angularly adjustable on the yoke, a pad frame in sliding frictional engagement with the yoke frame having cover slots at either end, a cover roll rod on the frame, a roll of flexible material whose end is drawn in and out through the slots and a clamping finger on the pad frame adapted to press the roll strip against the pad frame when the latter is near one end of its limit of movement on the yoke frame.
2. A head rest for chairs comprising a support, a yoke secured thereon, a frame angularly adjustable, a pad frame in sliding frictional engagement with the yoke having a cover slot at each end, a pad on the outer face of the latter frame between the slots, a cover roll of flexible material journaled on the frame behind the pad frame with its strip threaded through the slots over the pad and a spring finger secured at one end on the under face of the pad frame with .its free end over one of the slots, the yoke frame being adapted to force the finger against the strip and pad frame when the latter is near one end of its limit of motion.
3. A head rest for chairs comprising a supporting slide bar, a yoke detachably secured thereon, a yoke frame angularly adjustable on the yoke, a curved pad frame in sliding frictional engagement with the yoke frame having a pair of cover slots, a pad on the pad frame, between the slots, a spring finger on the under face of the pad frame extending over one of the slots and a cover roll of flexible material journaled on the yoke frame with the end portion of its strip threaded through the slots over the pad of the pad frame, the yoke frame being adapted to force the spring finger against the strip and under face of the pad frame when the latter is in one position.
4. A head rest for chairs comprising a support, a yoke on the upper end thereof, a frame angularly adjustable on the yoke, a curved pad frame having spring guides in sliding frictional engagement with the yoke near one limit of motion on the yoke frame.
5. A head rest for chairs comprising a support, a yoke transversely disposed on the support, a yoke frame consisting of side arms held in spaced parallel relation by cross members connecting their outer extremities, with their inner ends Divoted on the cross bar in abutment with the outer ends of the yoke, a longitudinally curved pad frame, spring guide rods on the under face of the pad frame in sliding frictional engagement with grooves on the sides of the yoke frame arms, a pad on the outer face of the pad frame extending between a pair of transverse slots in said frame, a spring finger secured against the under face of the pad frame with its free end across one of the slots, a roll rod demountably secured across a pair of the frame arms and a roll of flexible cove-ring material on said rod with its end portion threaded through the slots over the pad and between the spring finger and pad frame, the spring finger being forced against the strip and pad frame by the adjacent cross member of the yoke frame when the pad frame is near one limit of movement on the yoke frame.
In testimony whereof I afiix my signature in presence of two Witnesses.
