BARBERS-CI-IAIR HEAD-REST.

o'rasas.

To all whom it may concern:

Be it known that I, HENRY E. CAMPBELL,

a citizen of the United States, and a resi dent of Bridgewater, in the county of Adair and State of Iowa, have invented certain new and useful Improvements in Barbers- Chair Head-Rests, of which the following is a specification, reference being had to the accompanying drawings.

This inventionhas relation to certain new i and useful improvements in head rests for barbers chairs.

The primary object of my invention is to provide a headrest, adapted to be used in connection with a barbers chairthough the same may alsoibe used in connection with a dentists or like chair, arranged so that the same can be carried out of working position without detachingthesame from the chair;

Another object is to provide a barbers chair with a carrying member giving pivotal support to the headrest, and constructed so that when said head rest is carried'out of its working position, the carrying memher will be automatically released, permitting the head rest being carried below the upper edge of the chair back, without detaching the same from the chair.

lWith these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within-the scope of the claims,without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1, shows aside elevational view of a barbers chair provided with a head rest embodying my invention. Fig. 2, shows a rear view of the rest also disclosing a broken portion of the top of the chair. Fig. 3, shows an enlarged detached detail of the bracket and connected cushion. Fig. 4, shows an end view of the bolt head. Fig. 5, isa detached detail of the spring detent used to hold the runner. Fig. 6, is an edge view of the spring detent. Fig. 7, is a detached detail of one of the springs Fig. 8, shows a fragmentary view of the back of the chair disclosing the chair groove and Specification of Letters Patent Application filed April 18, 1911.

PatentedNom18, 1913. Serial No. 621,753.

A barbers chair as ordinarily constructed includes ahead rest employed only during the shaving operation. lVhen the customer simply requires a hair cut, the head rest is in. the way of the barber and must be removed, the rest usually being entirely detached from the chair. In my present invention I provide a head rest which while vertically adjustable can be instantly thrown out of the way when not required, without detaching the same from the chair.

In the accompanying drawings the letter A, designates a'barbers chair of conventional construction to the back 1, to which is attached a head rest embodying my invention. As shown in Fig. 2, the back 1, of the chair is provided with a middle lengthwise running channel2, the edges of which are rabbeted or grooved as shown at 3, in Fig. l. The bottom of the channel 2, serves as a stop to a runner held therein. This main channel 2, near the upper end is further pro vided with a seat 5, which is continued at right angles to form the stub channel 6, as disclosed in Fig. 8. V

Held within the seat 5, is the stem 7, of a spring detent secured by means of suitable screws 8. This detent has a lateral extension9, arranged to liewithin the stub channel 6, an upstanding finger piece 10, being continued from the lateral extending portion 9. The portion 9, forms a pawl, the end being held a suitable distance above the bottom of the stub channel. In Fig. 6, I have shown the normal position of this spring detent. As shown, the operating portion 10, is located to the side of the channel 3, upon that side of the chair back.

Slidably held within the main channel 2, is a runner 20, this runner upon the outer face carrying the flanges 21, as shown in Fig. 9. This runner 20, freely slides within the main channel 2, and upon one side has the rack teeth 22, shown in Fig. 10, arranged for co-action with the spring detent 7., which is arranged to lie below and work against the rack teeth 22. near the upper end upon the face provided with the rack teeth" 22, is provided with a socket 23, and upon the edge with an opening 24, as clearly disclosed in Fig. 10. Secured to the edge a suitable distance below the opening 24, is an ear 25, this ear pivotally receiving the pawl 26, which has an outstanding lip 27, and upon the opposite side is, provided with a guide arm 28, as shown in Fig. 9, the guide arm sliding within a seat 30, below one of the metal flanges 21. This guide arm 28, has an outstanding car 31, limiting the outward movement of the pawl, in that this car contacts with a flange- 2 Held within the opening 24, and working against the pawl 26, is a. spring 32, which normally forces the pawl outward in a manner insuring the lip 27, projecting beyond the upper edge of the runner 20. In Fig. 13, I have shown a detail view of this pawl.

Secured to the lower end of the runner 20, upon one side is a finger piece 33, by means of which the runner may be raised. The spring detent 7, is normally in engagement with one of the rack teeth 22, of this runner and in order to release the detent, the operator presses upon the finger piece 10, resulting in the detent being carried out of work ing engagement.

Within the outer face of the runner 20, is

a bolt socket 34, shown in Figs. 4 and 9.

V and 12.

Slidably held below the flanges 21, is a plate 36, shown in Fig. 12, from one end of which extends the bolt head 37, as shown in Figs; 4

This bolt head has the upper slanting edge 39, provided with a middle length wise running groove 40, this groove at its upper end ending in an ear socket traversed by a pin 42. The outer face 43, of the bolt head carries two guide pins 44, which are positioned at the ends of a socket 45, as clearly disclosed in Fig. 12. Slidably held to the pins 44, is the bolt 47 having the outstanding gear 48, the pin receiving slots 49, and the eye 50, as clearly disclosed in Fig.

.11, where a detail of this bolt is shown. It

is within the slot 49, that the pins 44, are slidably held. The outwardly directed ear 48, is arranged to work within the socket 45, as disclosed in Fig. 12. Suitable nuts 51, are secured to the stems 44, to slidably hold the bolt to the bolt head. Held within the socket 45, and against the bolt 47, is a spring 53, which at its upper end works against the socket end, while at its lower end this spring rests upon the ear 48, so that this bolt is held in spring pressed condition, normally being forced outward beyond the base edge of the plate 36, as will be understood in referring to Fig. 12.

Pivotally held upon the pin 42, is a trip, preferably made of wire, including the striker end 56, held outward of the edge of This runner 20, l the bolt head and from which is continued a coil 58, winding about the pin 42, the stem 60, of this trip'being arranged to lie within the groove 40, with its end engaged within the eye 50, of the bolt 47, as shown. In depressing the projecting end 56, the stemof the trip is thrown outward to actuate the bolt 47. This bolt 47, is arranged for coaction with the slot 34, within the runner 20.

As shown in Fig. 12, the bolt head 37, is provided with an apertured ear 61, while projecting laterally from the bolt head are the trunnions 62, these trunnions being clearly disclosed in Fig. 4. Hingedly con-v nected to the ear 61, is the bracket 63, this bracket being pivotally held to the bolt head by means of the pin 64, passing through the ear 61, while extending from opposite sides of this bracket are the trunnions 65, shown in Fig. 3. Near its upper end this bracket has a pawl slot 66, arranged for coaction with the pawl lip 27. At its uppermost end the bracket 63, carries a block 67, to the edge of which is secured a pneumatic tube 68, Having an inflating nozzle 69, as is usual. The pneumatic tube is secured to the block 67, by means of the fabric 7 O, which is fastened to the block by means of suitable tacks or screws 71. his member 67, in connection with the pneumatic tube, forms the 9 head rest proper of my invention and is of a shape adapted to conveniently receive the back of a human head. Secured to the trunnions 62, and 65, is a spring including two similar arms 73, and 74, having an inter-. mediately positioned spring coil 75. The arms end in the eyes 7 6, the eye of the arm- 73, being arranged to be securedto the trunnion 62, while the eye of the opposite arm 74, is arranged to be brought into engagement with the bracket trunnion 65, so that the bracket 63, is normally thrown in a direction insuring the bracket being held in a spring pressed condition against the back of the chair. There are two such springs employed to force the bracket upward. As shown in Fig. 12, the end 56, of the trip is in the path of the lower beveled end of the bracket so that when this bracket is released from the runner and is carried rearwardly, it will engage the trip end 56, to actuate the trip to release the bolt 47, from its socket 34, so that the plate 36, and connected bolt head will drop to the bottom of the runner, being stopped against the finger piece 33. In this position, as is shown in Fig. 14, the head rest will be held below the upper edge of the chair back and entirely out of the way of the operator.

The runner 20, is held in its channel by means of the face 3.

The operation of my device is very simple. The runner 20, is first inserted into the channel 2, of the chair back so that the same is stopped against the bottom thereof. In this position the spring detent 7, will be just above the uppermost rack tooth 22. The bolt plate 36, is next inserted and slid downward until the bolt 47, finds a seat within the socket 34. In this position the upper end of the bracket 63, will rest upon the upper end of the runner, as clearly disclosed in Fig. 3. In this position the pawl 26, is in engagement with the bracket to hold the same to the runner. upward and given proper adjustment. Should it then be desired. to throw the head rest out of working position, the operator simply depresses the pawl 26, so that the same will ride free of the bracket socket and carry this bracket 63, backward. In doing this the bracket automatically trips the bolt 47, carrying the same out of the slot 84:, so that the head rest can be dropped below the upper edge of the chair. The runner can then also be lowered.

A head rest constructed according to my invention is simple and inexpensive in construction and both durable and eificient in operation, and the adjustments can be made with ease and accuracy. An incident of convenience to this arrangement of head rests for barbers and other chairs, is that the same can be instantly thrown to the rear of and below the upper edge of the chair back without detaching the head rest from the chair.
