ATTACHMENT FOR HEAD SETS.

Application filed December 8, 1923. Serial No. 679,370.

To all whom it may concern:

Be it known that I, HENDERSON P. CHIL- DREss, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Attachment for Head Sets, of which the following is a specification.

This invention relates to an attachment for head sets such as are used by telephone operators, and also in connection with radio receiving instruments to support the receivers against the ears of the person receiving the message.

In devices of this kind, the head band frequently causes the receivers to exert considerable pressure on the ears, so that the continued use thereof becomes painful. Then too, a head band which lits the head of one person may not lit that of another, and in the case of radio receivers, which are frequently used by a great number of diEer'- ent persons, it becomes particularly desirable to have some means of quickly adjusting the normal width of the head band and adapting it to different persons.

The general object of the present invention is to provide a practical device, which may be easily manipulated to adjust the receivers for use under different conditions, and relieve the pressure on the ears without removing the device from the head. The invention is in the nature of an attachment, which may be applied to any ofthe usual types of head sets in a few moments even by an inexperienced person.

The present invention is related to my application No. 639,871., liled May 18, 1923, and is generic to the construction therein shown.

The principles of the invention will be best understood from the following detailed description, in which reference is made to the accompanying drawing showing the preferred construction of the invention.

In the drawing: v

Figure 1 is a front elevation of a head set having my invention attached thereto.

Figure 2 is a vertical sectional View taken longitudinally of the attachment.

Figure 8 is a detail sectional view taken on the line 33 of Figure 2.

Figure 4 is a detail perspective view of one of the threaded stems by means of which the adjustment of the device is affected.

Figure 5 is detail perspective View Showing aV modified form of the attaching member.

The invention, as sho-wn, is' applied to an ordinary head set, which includes a band 5 adapted to embrace the upper portion of the head, and terminating in collars 6 in which the stems 7 are mounted for vertical adjustment. These stems are formed with yokes 8 at their lower ends, in which are mounted the respective receivers 9. Each of the stems 7 is held in its position of adjustment by a lock nut V10, and usually a small knob 11 is threaded to the upper 'end of the stem to prevent'the same from being entirely separated from the head band.

The attachment includes a pair of oppositely curved attaching members 12, each having suitable means of attachment to the corresponding receiver stem 7 at each side of the collar 6. In the form shown in Figures l, 2 and 3, the members 7 and 12 are secured together by means of clamps, each of which includes a pair of spaced transverse strips 13 spanning the members 7 and 12, and having opposed concave portions 141 adapted to grip the respective members 7 and 12 between them. A small bolt 15, or equivalent means may be provided for securing the clamp. The lower end of themember 12 may be upset, as shown at 16, so as to prevent the clamps from slipping olf.

The upper inner ends of the members 12 have inwardly extending threaded stems 17 pivotally connected thereto. Any form of pivotal connection may be used, that herein shown consisting of a pin 18 extending from the end of the stem 17, through an eye in the end of the member 12, and having its end upset tov form a permanent connection. The threaded portions of the stems 17 are connected by a-turnbuckle 20 for adjusting them to and from each other.

In the modification shown in Figure 5, the attaching member 12a has` its lower end turned laterallyto form a horizontally disposed ear 21, which is perforated, as at 20, to receive the stem 7. A secondear 23 isattached to the member 12El by riveting or welding, and is spaced vertically above the .car 21 and parallel thereto, and is also provided with a perforation 24 for receiving the upper portion of the stem 7.

cluding` a head band, stems mounted for vertical adjustment in the ends of the band, and receivers supported by the stems, of an attachment comprising a pair of members having means independent of the band for engaging the receiver supporting stems at spaced points, threaded stems pivotally connected with the respective members, and threaded means cooperating with said threaded stems for rocking said members to adjust said receiver supporting elements about their connections with the head band as fulcrums.

l0. An attachment for a head set having a head band with receiver supporting Stems mounted in the ends thereof, said attachment comprising a pair of members, each having a pair of laterally extending perforated ears parallel to and spaced from each other and adapted to receive the receiver supporting stem on opposite sides ofits connection with the head band, threaded stems pivotally connected with the respective members, and a turnbuckle operatively connected with said threaded stems.

11. A head support of the character described comprising a head band, stems mounted in the ends thereof for supporting the receivers, and means connecting the stems independent of the head band and operable to rock said stems simultaneously in opposite directions about their points of connection to the ends of the head band, to move the receivers toward and away from each other.

l2. A head support of the character described comprising a head band, stems mounted for vertical adjustment in the ends of the band, and means independent of the head band for rocking the stems about their connections with the head band to adjust the relative angular relation thereof.

13. A head support of the character described comprising a flexible head band, stems mounted in the ends thereof for supporting the receivers, and means independent of the head band for simultaneously rocking the stems in opposite directions and flexing the band to move the receivers toward or away from each other.

14. A head support of the character described comprising a head band, stems mounted in the ends thereof for supporting the receivers, and means connecting the -stems independently of the head band and including two members connected by a turnbuckle operable to rock the stems simultaneously in oppositev directions to vary the distance between the receivers.

l5. The combination with'a head set, comprising a head band and stems mounted in the ends thereof for supporting the receivers, of an attachment comprising spaced members adapted to embrace the head, clamps for removably securing said members to the corresponding receiver stems at each side of their connection with the head band, and means to move the upper ends of said members toward or away from each, other to adjust the receivers toward or away from the ears.

16. An attachment for a head set, comprising a pair of opposed members provided with connecti-ons for detachably engaging the receiver stems on the head set, the upper portions of said members being curved inwardly and having pivoted ends which are threaded right and left respectively, and a turnbuckle cooperating with said ends and adjustable to move the receivers of the head set away from the ears of the operator to relieve the pressure thereon.

17. An attachment for a head set, comprising a pair of members having curved portions, means for detachably securing said members to the receiver stems of the head set with the curvedjportions in opposed relation to each other and adapted to overhang the head of the operator independently of the head band of the head set, end portions pivoted to the ends of the curved portions and threaded right and left respectively, and a turnbuckle connected with the threaded ends and adjustable to relieve the pressure on the ears of the operator.

In testimony, that I claim the foregoing as my owns I have hereto affixed my signature.

HENDERSON P. CHILDRESS.
