HEADRE$T FOR BARBER OR LIKE CHAIRS.

Application filed June 9, 1921. Serial No; 476,173.

To all whom it 'nmy concern.

Be it known that I, Grosnrrn Canrrnno LARAIA, a citizen of the United States of America, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Inn provements in Headrests for Barber or like Chairs, of which the following is a specification.

This invention relates to head-rests for barber or like chairs, and aims to provide improvements therein.

The invention provides simple and etlec tive means for fastening the head-rest proper in various positions around its point of support.

The invention further provides simple and effective means for adjusting the height of the head-rest, and which is combined with the back-rest of the chair in. such manner as i to have a pleasing appearance.

The invention further provides combinations and subcombinations of parts, hereinafter set forth, for effecting in an improved manner the purposes of the invcntion. r

An embodiment of the invention is il lustrated in the accompanying drawings,

' wherein Figure 1 is a view in vertical section of a headrest, and so much of the back-rest of a chair as is necessary to illustrate the com 'blllit-tlOllt i Fig. 2 15 a vertical section at right angles to the view in Fig. 1;

Fig. 3 is a. view similar to Fig. 2, illustrating the preferred form of embodiment Ofthe locking means for the head-rest;

Fig. l is a view on the line 1V -1V, Fig. 1;

Figfo is a section on the line V V,

a u n l i Referring to said drawings, numeral 10 designates a back-rest comprising a frame 11, and 12 designates a head-rest. The headrest conveniently comprises a head-rest proper, 13, and a post 15, preferably supandin which it is guided. Means are pro vided for holding the post 15 at various heights of projection beyond the back-rest.

and for this purpose the post 15 is conveniently provided with a series, 22, of ratchet.

teeth, and a pawl 2 1011 the inside of the backrest is provided for engaging the said ratehet teeth 22 of the post. The back-rest frame 11 is conveniently provided with an opening 26 through which the pawl 24 may be reached and pressed to release it from engagement with the teeth 22. The end of the pawl 24 opposite the opening 26 is conveniently provided with, a hollow projection 27 which projects into the openin 26, and a spring 29 for pressing the pawl 24. into engagement with the teeth is conveniently locarted and retained in the hollow part of the said projection 27. The pawl 24 is conveniently pivoted to a lug plate 31, as indicated at 33, which lug plate is conveniently secured to the inner side of the back-restframe 11, as indicated at 34, Fig. 1. The edge portion 36 of the opening 26 in the back-rest frame 11 constitutes an abutment or stop for engaging the pawl 24, for limiting its pivotal movement, when the post 15 is withdrawn. The lug plate 31 acts as a stop for the pawl 24, when pressed inward.

A pivotal connection 40 is conveniently provided between the head-rest proper and the post 15. This joint is conveniently in the form of a hinge or knuckle joint, the parts of which areconnected by a pivot pin 4-1. A stud43 having lateral frame extensions V1 is preferably interposed between the head-rest 13 and the pivotal connection 10.

Eahoulders 15 and. 46 on one of the parts of the oint (the post 15, as here shown), limit the turning of the head-rest around the piv otal connection in such manner that it is prevented from striking or coming into contact with the back-rest, and thereby injuring .the appearance of the parts.

Means 50 are preferably provided for locking the head-rest 13 in various positions around said pivotal connection 10. This means preferably comprises a manipulating part or handle 52 extending to one side of the headrest, and a locking pin 5 1 conveniently mounted in the stud 13 and engaging the post 15, as by means of sockets formed in the disk 53 of the joint 4-.Owhich is formed upon the said post 15. The locking pin 54- is conveniently pressed into engagement with the sockets 55 by a spring 57 bearing against a collar 56 and housed in an enlarged bore 59 in the stud 4:3. A bushing 60 in the end of the bore-59 provides an abutment for the other end of the spring and a guide for the upper end oi the locking pin 5%. The locking pin 54; is conveniently provided with a head or collar 63, and this is conveniently engaged bya cam 65 directly, as shown in Flgs. 1 and 2, or indirectly througha lever, 67, as shown in Fig. 3. The collar 63 may be in the form of a nut, threaded in the locking pin, and fixed against movement by a lock nut 68. as shown in Fig. 8. This construction admits or adjusting the time of contact between the collar 63 and lever 67. A fiat spring is provided for holding the end of the lever against the cam 65. This spring acts to automatically throw the manipulating parts to initial position when the manipulating piece 52 is released. The cam (55 is conveniently connected to the manipulating part or handle 52 by means or a rock shaft m In the construction shown in Fig. 3, the cam (35 is conveniently provided on its under side with a tlat- 71, so as to maintain a corresponding position in contact with the lever 67. Moreover, the arrangement of the parts is preferably such that when the locking pin 54 is pressed by the spring 57 completely into engagement with one of the sockets 55, the adjacent part of the cam (55 in the construction of Fig. 2, or the adjacentend of the lever 67 in the construction of Fig. 3, is out of contact with the collar 63, so that no resistance is oiiered by the manipulating mechanism to the action of the spring in pressing the locking pin into engagement with the sockets 55.

To change the position'of adjustment 'ot' the head-rest around its pivotal connection, it is simply necessary to turn the manipulating part or handle 52 in one direction or the other, causing the cam 65, either directly or through the lever 67, to raise the locking pin 'troniba socket The head-rest is then moved around the pivot ll to the desired position, whereupon the manipulating part or handle 52 is released or turned back, thereby allowing the spring to press the locking pin into another of the sockets 55. To adjust the height of the head-rest, the projection 27 of the pawl 24: is pressed, and the post 15 raised or lowered to the desired height,- and the pawl thereupon released to engage one of the rack teeth. "With rack teeth of the character shown, it will notbe necessary to press the pawl 24 in raising the post.

The inventive ideas may. receive other embodiments than those herein specifically illustrated and describe-d.
