' UNITED STATES PATENT OFFICE.

JOHN HENRY BUTCHER, OF RUGBY, AND ARTHUR PRIMROS E YOUNG, 01 N11;-

WORTH, ENGLAND, ASSIGNORS TO GENERAlZ ELECTRIC COMPANY, A CORPORATION OF NEW YORK.

TELEPHONE HEAD sn'r.

Application filed December 11, 1923. Serial No. 679,978.

To all whom it may concern:

Be it known that we, JOHN HENRY BUTCHER and ARTHUR Pnnsmosn YOUNG, subjects of the King of Great Britain, residing, respectively, at' Ru by and at Kenilworth, i n the county of arwick, England, have. invented certain new and useful Improvements in Telephone Head Sets, of which the following is a specification.

Our present invention relates to telephone head sets and has for'its object means whereby a cheap and eflicient head attachment may be constructed having ear-pieces which are easily and naturally adjustable tofit comfortably over the ears for use in the reception of telegraphy or telephony whether wireless or ordinary. A further object of this invention is the construction of a head set which is specially adapted for use by ladies so as to interfere as little as possible with their coifi'ure, the yoke of the ear-piece supports passing beneath their chins.

Our invention broadly consists 1n the construction of head sets so that relative move ment between the ear-pieces as controlled by levers or their e uivalent formed in-' tegrally with orattac ed to the ear-piece supports, the ear-pieces being normally helda predetermined minimum distance apart by resilient means.

Our invention further consists in providing the ear-piece supports with levers or an equivalent mechanism arranged in such a way that the hand of a person plckmg up the head set can at-the same time actuate these levers in a natural manner to move the ear-piece apart against the action of re-.

silient means.

It should be understood that the ear-pieces must be mounted upon their supports in a substantially rigid manner; that Is to say, if a mounting giving universal movement is emplo ed, means must be provided for limiting t is movement to a predetermined amount inorder to prevent the ear-pieces from falling into a position which would hinder the head set from being placed over the users ears.

The novel features which we believe to be characteristic of our invention are set forth with particularity in the appended claims.

Our invention itself, however, both as to its organization and method of operation will best be understood by; reference to the following description ta en in connectionwith the accompanying drawing in which Fig. 1 illustrates a preferred form of our invention and F1 2 is a view of the supporting member of ig. 1.

Referrlng now to Fig. 1, the ear-pieces 11 are mounted through any suitable connection providing limited universal movement, such as a ball and socket joint 12, upon supporting members 13, these latter bemg pivoted upon abolt 14 carried upon the handle 15. The conducting leads 16 may convemently be brought along the ear-piece supports, being held in position by hooks 17 and being united in .the neighborhood of the handle. At the ends of the supports away from the ear-pieces there are formed triggershaped levers 18 and projecting portions 19, between which latter 1s arranged a spring 20 adapted to draw the earieces towards one another. Stops 21 provided upon the supports are arranged to limit the distance that.

the ear-pieces can travel towards one another by bearing a ainst the upper end of the handle 15. T e supporting members, together with the trigger-shaped ortions form a pair of uncrossed tongs, an it will be seen that the levers 18 are so shaped and positioned, with respect to the handle 15 that, when a person proposes to use the head set, 1118 forefinger and thumb will naturally grasp the said levers; and upon applying pressure the ear-p1eces will be moved apart to enable the head set to be placed over the users ears, Upon his'withdrawing pressure fromthe'levers 18, the spring 20 draws the ear-pieces towards one another until they rest comfortably upon the users ears, whereupon the set is ready for the reception of telephony, etc.

What we claim as new and desire to secure by Letters Patent of the United where-bv said ear pieces maybe moved away whereby said ear pieces may be moved away from each other. from each other. 10 2.
