I mam HEAD REs'r '1 Blythe peck r, Princeton, 1nd,;

Application December 14, 1938, Serial No. 245,720 I 1 claim; (m me-41) I My invention relates to barber chairs and the like, and has among its objects and advantages the provision of an improved head rest embodying a vibrator unit. i 1

In the accompanying drawings Figure is a sectional view along theline 5--5 ofll'igure 3; 1 h p 1 Figure 6 is a sectional view along the line 6-6 of Figure 2; i

Figure '7 isa sectional view along the line l-A-I of Figure 6; and I Figure18 is a sectional view of the paper supporting roller. 1 1 In the embodiment selected to illustrate my invention, I make use of a head rest I0 provided with a conventional shank I2 which shank may be provided with a series of openings so that the shank can be adjusted vertically on a chair (not shown) in the usual manner. Head rest I0 includes end walls I4 recessed at I6 for housing the wall elements I8 which are notched at to provide teeth 22 to certain of which I attach the ends of coil springs 24 which support the usual pad 28. Wall elements I8 are inter-I connected into a unitary structure through the medium of

cross bars

28 and 30, and each wall element I8 is hingedly connected with its re 1 spective wall I4 through the medium of a plate 32 having a pivotal connection 34 with one end of the wall element. Thus, the wall elements I8 1 and the pad 26 are connected as a unit which may be swung from its full line position of Figure 1 to the dotted line illustrations therein to lend access to theroller 35 which carries the roll 38' of paper.

Figure 3 illustrates the paper as being pulled over the rounded edge 40 of the pad 26, backwardly across the pad and downwardly across 1 the inner face of the bar 30 to be fixedly related thereto through the medium of a clamp flange 42 arranged for pivotal movement about its axes 44 journaled in the side elements I8. Clamp flange 42 is provided with an arm 46having a finger grip 48 extending through an opening 50 in one of the walls I4. Clamp flange 42 is normally held in the position of Figure 3 through the medium of a tension spring 52. 1

I Figure 1 is a side elevational view of a head 1 Roller 36 is illustrated in FigureBpwhihroller includes a shaft 54 rotatablyjournaled at 56 in one of the walls I4. The other shaft 58 extends loosely through an opening in the end I flange 60 and is provided with a body 62 slidable 5 inside the tube 64 of the roller. Between the body 62 and a stop 66 I interpose a compression spring 68 which urges the shaft 58 to the which supports the head rest. T-head 80 in- 201 cludes a curvature 82 which accommodates the paper roller 38 and is detachably connected with the head I8 through the medium of screws 84. Disc 14 is pivotally connected with the ears I6 through the medium of the shaft 86, and the disc is provided with a plurality of openings 88 for selective reception of a latch pin 90 which is slidably supported by a tube 92 anchored to one of the ears 16 by screws 94. Latch pin 00 is provided with a flange 96 against which one end of a compression spring 98 bears for urging the latch pin into the aligned opening 88. The opposite end of the compression spring is arranged for abutting relation with the outer end of the tube 92. Thus the head rest I0 may be shifted to different positions about the shaft 86 as an axisand latched in such positions.

1 Head rest I0 is also adjustable about the horizontal head part I00 of the T-head 80. Figures Sand '7 illustrate the construction of the ends of the head part I00. Since both ends are constructed in the same manner the description of one will applyto both. Figure 6 illustrates one of the walls I4 as being provided with an offset I02 having a bore I04 loosely receiving the short shaft I06 which also extends into the bore I08 in the head part I00. 1

Between the inner end of the shaft I06 and the end of the bore I08 I interpose a compression spring I I0 which normally urges the shaft I06 to theposition of Figure 6. A transverse pin H2 is carried by the shaft I06, which pin is axially slidable in the slots H4 and projects beyond the outer diameter of the head part I00 sufliciently far to be brought into selective reception in the notches H6 for latching the'wall I4 against rotation about the shaft I 00 as an axis. Head part I00 is rounded at II8 to take the form of a shaft rotatably disposed in the bore I20 in the inner face of the wall I4. Thus circular wall I28 which is secured thereto through the medium of screws I30.

Upon the bar I24 I mount an electromagnet I32 andbrackets I34 each of which supports a vibrator head I35 which is mounted on a short post I36 carried by the outer end of a strap I30 secured at I40 to the inner end of its respective bracket I34. Each bracket is provided with an armature bar I 42 arranged in operative relation with the .pole I44 of the electromagnet. Each vibrator head I34 is of the same construction. Figure 5 illustrates, the posts I35 as extending loosely through openings I46 in the semi-circular wall I20, while Figure 1 illustrates the head rest I0 shifted to such a position as to bring the vibrator heads I34 into vibrating relation with the neck part I48 of the person being treated. Electromagnet I32 is connected with wires I50 and I52, one of which is connected with a con ventional' switch I54'and the other connected with a terminal I50'of the electric cord I58. A wire I is connected with the switch I54 and the other terminal I52 connected with the other wire in the cord I58. Closing of the switch 554 will energize the electromagnet I32. Alternating current impulses excite the electromagnet intermittently and cause the armature bars. M2 to be attracted thereto for imparting vibratory action tothe vibrator heads I34.

It will thus be seen that the head rest I0 may be utilized in the manner of conventional head rests such as are employed in connection with barber chairs, but the head rest maybe adjusted to the position of Figure l for bringing the vi brator heads I34 into operating position. The head rest is additionally adjustable about the shaft I06 as an axis which permits a large range of adjustment of the head rest for operating purposes beyond the range of the adjustment about the shaft 86 as an axis.

Cord I58 is connected with a detachable plug I64 so that the cord may be detached when the head rest is not being used ,for massaging purposes. merit, the person being treated may take a reclining position in the chair with the head rest positioned according to Figure l. Vibrating heads I34 are so aranged in the head rest structure as to be completely out of the way when the head rest is adjusted for bringing the pad 26 in the usual head and neck supporting position.

I claim:

In a head rest of the type described, a support adapted to be pivoted to different positions about a horizontal'axis, a head supporting pad on said support, neck massaging means, electromagnetic means carried by said support, and means for operatively connecting said massaging means with said electromagnet, said support being adjustable to a position for supporting a patients head on said pad with said massaging means located to massage the neck of the patient, and said support being adjustable to another position for locating the head of the patient. on said pad but with said massaging means out of range of the patients neck.
