TELEPHONE HEAD fiET.

Application filed Gctober a, 1918. serial No. 56367.

To all whom it may concern:

Be it known that l, JOHN S. TIMMONS, a citizen of the United States, and resident of New York, county of New York,'and State of New York, have invented an Improvement in Telephone Head Sets, of which the following isa specification.

My invention has for its object, the construction of a suitable telephone head set for W aeroplaneists and those whose duties are in the vicinity of causes of great noise and where intercommunication by articulate speech is practically impossible.

My invention has for a further object, the

w construction and combination of the helmet and ear pieces in which the telephone receivers are arranged, in such manner that the ear pieces may be adjusted higher or lower to suit heads of different shapes,

whereby while the crown of the head may firmly fit into the helmet the ear pieces and the receivers suspended therefrom may be adjusted to properly fit the ears of the operator.

A further object of my invention is to provide the adjustable ear pieces at their lower portions with a .connecting chin strap for olding the ear pieces snugly to the ears and also for supporting a transmitter and pressing it t" htly against the throat.

With the a ove and other objects in view, the nature of which will be more fully understood from the description hereinafter, the invention consists in the novel construction of telephone head sets as hereinafter more fully described and defined in the claims.

Referring to the drawings: Fi 1 is a side elevation of a telephone hea set embodying my invention Fig. 2 is a front elevation of the same with a portion of the hel met broken away to show manner of suspending the ear pieces; Fig. 3 is a vertical section through the ear pieces and showing the receiver in place; Fig. 4 is a ve'rtical section of a part of the chin strap and showing the transmitter in place thereon; and Fig. 5 is a general view showingilthe telephonic apparatus removed from t e ear pieces and chin strap.- a v 1 is the helmet proper and may be made of any Suitable material which Wlll provide strength. and durability. In practice a I prefer to employ sole leather sections molded or shaped and sewn together and the whole lined with a suitable padding material 2. The rear portion of the helmet is preferably extended down to fully cover the back of the head and thus increase the protection against injury. At each side of the helmet above the place where the ears of the wearer willcome I provide slots 5 through which suspension straps 4t of the ear pieces 3 extend from inside outward, said straps having holes and secured in adjusted position by buckles 6. It will be manifest that by this construction the

ear pieces

3, 3, may be held to the cars by the sides of the helmet and their vertical position may be adjusted relatively to the crown of the helmet to exactly adapt them and their receivers 9 to the ears of the operator.

The ear pieces 3 are preferably circular and formed of leather or other strong material and comprise flanged pockets having the inner faces of the flange portions rovided with soft annular padding 7 w ich may be pressed to the sides of the head snugly around the ears. Fitting in the pockets are soft rubber cases 8 for holding the telephone receivers 9, said rubber cases having flaring bell-shaped flexible rims 8 which, in use, completely shut out all extraneous sounds from the ears, all of which is shown in Fig. 3. At the lower lportion of each of these ear pieces is a meta loop 14, suspendedfrom the flange portion thereof by leather straps 13.

15 is a chin strap having its

ends

15 and 15 threaded through the loops 14 of the ear pieces and, by

ends

15 and 15 may be adjustably united to provide any tightness desired under the padding 19 of felt or other suitable materia 20 is a soft cover, preferably of textile ma terial, fitting over the transmitter'and closing the entrance to the pocket 1'l said cover having one end sewn or otherwise attached means of a buckle 16, said.

chin and as a result thereof, simultaneously 4 Elli to the strap 15 "at 21 and its other end do tachably attached to the strap by a snap fastener similar to those used upon gloves (Fig.

4). The use of this cover 20 is to keep the metal of the transmitter away from direct contact with the throat and to retain the transmitter in the pocket when the head set is not in use. As it is most important that the transmitter be pressed against the throat with a pressure sufficient to secure action of the muscular vibration thereof during articulate speech, I prefer that the strap end 15 shall extend under the bottom of the wall of the pocket 17 and thus press the pocket and transmitter upward in a positive manner, the

portions

15 and 15 of the chin stra acting as tension members thereof for app yinlg positive inward pressure concentrated upon the transmitter, as indicated in Fig.

The telephonic apparatus adapted to my improved head set is shown in Fig. 5 1n which the receivers are connected by a cable 11 which is arran ed at the back of the helmet and detachab y secured in lace by a snap loop 12 on the helmet (Fig. 1 A second cable 25 runs from the receiver 9, for the right ear, to the transmitter and a third cable 26 runs from the receiver 9, for the left ear, to the coupling or connector terminal 27 for connect1on with the line circuit leading to the other operator directly or through a switch board (not shown). If desired,,these parts may be reversed, according as to whether the operator desires the transmitter to come to the right or left side of the throat. The rubber cases 8 have inward flanges 10 (Fig. 3) which retain the receivers in the pocket formed by the case. The use of these rubber cases 8 and flaring rims 8 not only act to hold the receivers, but also act as dampeners against external air vibrations reaching the ears or receivers. By the construction here shown, the telephonic apparatus may be quickly introduced or removed from the head set or helmet. W In adjusting this head set to the operator, the helmet 1 is first set firmly upon the head, the ear pieces are then adjusted vertically to exactly cover the ears, and finally the chin strap is adjusted to both position the transmitter to the throat and provide the necessary pressure of both the receivers and transmitter to the head of the operator. It will now be apparent that 1 have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while have in the present instance shown and described the referred embodiment thereof which has een found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification antenna in various particulars without departing from the spirit or scope of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is:

lpA telephone head set consisting of a helmet, combined with separate ear pieces loosely connected to the helmet with capacity for vertical and free lateral adjustment relative thereto and containing receivers, and an adjustable chin strap connected with the lower portions of the ear pieces for holding the helmet in position and the ear pieces close to the ears and in which further the ear pieces are shaped to provide flanged pockets for reception of the telephone receivers and having flanges fitting yieldingly about the ears by their own resiliency and also having annular paddin secured to the inner surfaces of the flange portions thereof, said annular paddin being outside of and'independent of the exible flanges.

2. A telephone head set consisting of a helmet, combined with separate ear pieces loosely connected to the helmet withcapacity for vertical and free lateral adjustment relative thereto and containing receivers, and an adjustable chin strap connected with the lower portions of the ear pieces for holding the helmet in position and the ear pieces close to the ears and in which further the adjustable connection between the helmet and ear pieces consist of upwardly extendin straps from the ear pieces threaded throng slotted portions in the helmet and adjustably secured to the outside of the helmet by means of buckles attached thereto, said ear ieces extending up within the side Walls 0' the helmet.
