UNITED STATES DOUGLAS STUART SPENS STEUART, OF LONDON, ENGLAND.
Application filed October 24, 1927, Serial No. 228,363, and in Great Britain October 25, 1926.
The present invention relates to improvements in or relating to headgear attachments for listening devices such as receivers and the like, and also for use in conjunction therewith devices for holding transmitting devices in position.
The invention, While being more particularly applicable for headgear attachments for telephone receivers, is also applicable for headgear attachments for listening tubes and speaking tubes. In order to apply a headgear attachment to the head it is usually necessary to employ tivo hands for holding the receivers apart While placing in position on the head and for removing therefrom.
One of the objects of the present invention is to enable a headgear` attachment to be affixed to the head by a single hand, and according to one feature of the present invention this is attained by pro riding means adjacent one side' of the head in the `vicinity of the listening device for effecting the opening of the attachment so as to permit it to be placed on or removed from the head, so that the hand, after placing the listening device to the ear in a similar manner to which an ordinary telephone receiver is placed and adjusting it to the most comfortable position, can release the attachment so that it Will close round on the other side of the head and effectively hold the receiver in position after the hand has been removed. Other arrangements for effecting the opening of a headgear attachment so as to permit it to be placed on or removed from the ear have been provided with controlling means above the head so that the adjustment ofthe receiving devices to the ear is very indirect and not nearly so conveniently attained as by the present invention.
Another feature of the invention concerns the provision of a spring controlled drum located at one side of the headgear attachment having a band connected thereto of flexible material, such as ribbon, leather or the like, and tensioned thereby, which band extends to the other side of the attachment and so presses on the head and avoids the discomfort of the usual constructions. This is particularly of value in constructions such as the present Where pivoted arms are employed instead of a continuous strip of metal.
A further feature of the invention is an arrangement by Which a mouthpiece may be held in position in front of the mouth by a connection extending from the headgear attachment.
These and other features of the invention will be better understood by referring to the accmnpanying drai'vings, in which the single ligure is a view in front elevation, showing the headgear attachment as fitted to the person. As here illustrated, the headgear attachment comprises two arms 11 and 12 pivoted at 13. The arm 11 has an extension piece 14 and has a slot 15 at its outer end. A pin 16 on the end of a rod 17 engages in the slot 15, so that by moving the rod 17 up and down, the arm 11 can be moved from the position shown to the dotted position. The arms 1l and 12 are preferably tubular and the arm 12 is provided with a slot Whereby the rod 17 can slide up and down therein. To the rod 17 a. handle member' 18 is attached, as shown, While to the arm 12 a handle member 19 is attached. These two handle niembers are provided With pins 2O and 21, over Which fits a helical spring 22, Which acts normally to hold themapart, as shown, and so forces the rod 17 upwards, andtherefore causes the arm 11 to press against the other side of the head. The arm 11 carries at its extreme end a pivoted member' 28, and a cylindrical drum 24. This cylindrical drum is provided internally With a clockwork spring 25 tendingl to rotate the drum counterclockwise. To the surface of the drum is attached a band 26, preferably of light flexible material, such as ribbon, leather or the like. The other end of the band 26 is connected to the end of the arm 12 so that the band is normally tensioned, as shown. Atthe end of the pivoted member 23 an ear pad 27 is pivoted, which pad is adapted to adjust itself to the ear or against the side of the head of the user when in position with the minimum amount of discomfort. At the end of the arm 12 is a support 28 for an electromagnetic receiver 29 fitted With an ear pad 30; The receiver is pivoted in the support 28 so as to adjust itself to the ear. Connected to the receiver or to the end of the arm 12, whichever may be more convenient, is a flexible connecting link 31.' This connecting link is made of suitable material so as to support in any position to which it may be put a mouthaiece 32 connected to the end oi' a flexible tube 33 leading from a lined transi'nitter attached to an instrumentv from which the cord 34 extendsto the receiver. The purpose oifthis connecting link is that when the receiver is applied to the head the mouthpiece comes directly in front of the mouth and the user can talk with his hands perfectly tree. To apply the receiver to the head the ieceiver"\vould usually b e brought to the position shown in dotted lines, with the manually operating members 18 and 19 pressed together sorthat part-y concer-neder torl anotherl party. It it4 Was not for him, the called part-y couldnt Once replace the receiver Without atliiring theheadgearattachment. 1t it was tor the party Who had lifted the receiver, he would' their, having: atlixed the receiver to his ear, releaselhis grip so that the spring 22 would come into play to force-the members 18 and 19 lapart, andthereby cause the arm 11 to move tothe position shown intull lines. The band4 26 would then engage the heady in a manner likely to cause the least possible'disturbance, While the ear pad 27 would adjust itself to a comfortable position on the other side of the head. The hand could then be nally4 removed, any further slight adjustment could be made if required, and the subscriber Would haveboth hands free. In connection With pillar-type instruments, for Which the invention is particularly suitable, the flexible tube 83,: which may be ot the character described in my copending application Serial No. 242,941, iiled-Dec. 27, 192'?, and-Which extends from the transmitter oi the pillar set to the mouthpiece 32, may be brought by means ot the connecting link 31 in iront of the mouth ot the user at the same time as the receiver is placed inposition near the ear. `With such an arrangement both hands would be free immediately the receiver was adjusted and the desk in front of the subscriber Would be clear so that be could either readifrom papers on the desk or write as may be desired.
