HENDERSON P. UHILDRESS, OF MEMPHIS, TENNESSEE.

HELD SUIPPOR'I. FOR BADIOBEGEIVERS AND THE LIKE.

Application filed Kay 18, 1923. vSerial No. 639,870.

To all whom it may co ncem:

Be it known that' I, HENDERSON P. CHIL- nnnss, a citizen of the United States, resid ing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Head Support for Radioreceivers and the like (Case A), of which the following is a specification.

This invention relates to a head support for radio receivers and. the like, which is adapted to embrace the head and to support the receivers against the ear of the person receiving the message."

In devices of this kind, the head band causes the receivers to exert considerable pressure on the ears, and the continued use thereof often becomes painful. It is also necessary when the listener desires to carry on local conversation to remove the device from the head, or at least to raise it manually from the ears in order to hear. When this is done a part of the radio message may be lost. 4 Y

The general object of the present invention is to provide a practical device whereby the relation of the receivers to the ears may be adjusted to suit these diiferent conditions and to relieve the pressure on the ears by a simple adjustment without rpmoving the device from the head. The invention is in the nature of an attachment which may be applied to the ordinary receiver support, and one of the importantfeatures is the fact that it may be attached even by an inexperienced person, in the shortest possible time.

The principle of the invention will be best understood from the following detailed description in which reference, is made to the accompanying drawings showing the preferred construction by means of which the invention is carried out.

In the drawings:

Figure 1 is a front elevation of a head support, with my invention attached there- 'to Figure 2 is a plan view of the invention, looking from the line 22 of Figure 1.

Figure 3 is a sectional'view on the line 33 of Figure 2..

Figure 4 is a sectional view taken on the line l -4 of Figure. 3.

Figures 5, 6- and 7 are detailed views of the means by which the invention is at-' tached to" an ordinary head support.

to clamp the stem 12 in any position to which it may .be adjusted. A knob 15 is threaded into the free end of the stem 12, normally preventing the latter from being entirely removed from the collar 11. The lower end of the stem 12 carries a yoke 16 between the "arms of which a receiver 17 is pivotally mounted. The band 10 is so tensioned that when the device is placed in position on the head'of the person receiving the message, the receivers 17 press tightly against the ears holding the device in position and excluding all sounds except thosebeing transmitted through the receivers.

My invention includes a pair of resilient strips 18 held together atthe inner end by a rivet 19 or the like. and having their outer portions offset from each other to form a yoke 20 which embraces the stem 12. This yoke 20 formed by the strips 18 is held for longitudinal adjustment on the ing 27 through the head 22 of the screw has 1 the sides thereof bevelled as at 28. to permitouter extremities of the arms 21. The opena limited rocking movement of the screw 1 and yoke, whereby to adjust the same to fit the head of the person using the receiver.

.The arms 18 are held tightly together at their inner ends, and are tensioned so that the arms of the yoke 20 are urged toward eachother to frictionally engage the stem 12, and thereby hold the yoke 1n any. pos tion longitudinally of the stem to which it may be adjusted.

The inner end of the yoke carries a flat base 29, which is padded on its inner side, as at 30, to provide a cushion where it rests against the ear. In order to attach the base 29 to the arms 18, cars 31 may be stamped out of the material of the base and secured by the rivet 19, as seen in Figure 4. The inner ends of the strips 18 are made squareand slightly spaced from the base 29, as seen at 32, whereby the base may have a limited movement about the rivet 19 to adjust the angular relation of the same to tit the head.

it will be understood that by manipulation of the thumb nut 24 the latter may be adjusted on the screw 21 to move the yoke 20 longitudinally on the screw and with respect to the stem 12 to any extent desired. Thus the receivers 12 may be adjusted to relieve the pressure upon the ears while they are supported in the desired position by means of the attachment, the base 29 of which rests against the head. The receivers 17 may thus be adjusted away from the ears if desired, suiiiciently so that the person wearing the head support may carry on conversation, while at the same time the receivers are held in position for receiving any message which is delivered over the wires.

In the modification shown in Figure 8 the yoke 33 is similar to the yoke 20, above described, except that the jaws at its extremity are eliminated and a cam 34 is substituted for the adjusting screw 21. The cam 34 has a slot 35 through which the stem 12 passes, and is provided with a number of notches 36 along the edge of the slot for engaging the stem 12 to hold the cam in adjusted position.v The cam is formed with an excentric portion 37 having a series of notches 38 engaging the yoke, whereby the latter may be adjustably held to limit the distance between the base 29 and the stem 12.

In the modifications shown in Figure 9, the base is pivotally supported by an arm 39 having a slot 40, which receives the stem 12, the latter passing through a plate 41 which is adjustable longitudinally of the arm 39 by means of a set screw 42.

It is to be particularly noted that by removing the knob 15 and lock nut 14, the stem 12 may be removed from the collar 11, whereupon the device which constitutes my invention may be readily slipped on to the stem 12, and the latter replaced in its proper position on the instrument. The invention therefore may be sold separately as an attachment and installed on the instrument without the least difliculty.

While Ithave shown in detail a number of different structures by means of which the principles of the invention may be carried out, it is to be understood that these are merely for the purpose of illustration,

narrates and that various other means may be devised for supporting the head engaging portion 29 with respect to the stem 12 which supports the receiver, the basic idea of the invention being to provide a support both for relieving the pressure from the ears and for adjusting the receiver toward and away from the ears. The invention is adapted for use in connection with any head supported receiver.
