S UPPORT FOR HEAD TELEPHONE RECEIVERS.

Application filed December To all whom z't-may concern Be it known that I, HARRY It. CLARKE, a citizen of the United States residing at East Orange, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Supports for Head Telephone Receivers, of which the following is a full, clear, concise, and exact description. I

This invention relates to telephone apparatus and particularly to supports for head telephone receivers.

The object of the invention is to provide an improved construction for head telephone receiver sets, whereby they will readily adapt themselves to the head and ears of the user and will be free from moving parts or oints likely to catch the hair of the user or cause other discomforts when placed in or removed from position of use.

In accordance with the general features of this invention the adjustable hinged or movable connection between the head band and the receiver support is covered or concealed by a rounded smooth member which prevents abrasions of the skin or catching in the hair of the user. More specifically the invention contemplates the use of a thimble or casing secured to the head band and within which the receiver support is swiveled thereby covering movable parts likely to extrt a pinching or an abrading action.

F 1 a head set embodying the features of this invention.

Fig. 2 is a cross section of the swivel joint used as a connection between the'head band and the receiver support.

Fig. 3 is a transverse section through the swivel joint at 33.

Fig. a is a transverse section through the swivel joint at l4.

Fig. 5 is an exploded view of the swivel joint.

A wire band 6 preferably made in one piece is provided at one end with a small rubber block 7 pivotally supported on the right angle portions 21-21. The block 7 may be provided with perforation 24 within which the portions 21-21 terminate, and are preferably joined by means of the sleeve 22 soldered thereto to prevent their disengagement from the block 7. The block 7 serves as a pad presenting a la ge supporting sura, 1922. Serial No. 605,625.

face which permits the receiver being'held snugly against the car without undue pressure of the wire band on the head. The other end of the wire band 6 is provided with a right angle bend 8. A receiver unit 9 is pivotally supported by studs 11 in a fork 10 comprising a yoke 23 and a rod 12 rigidly attached thereto. The upper end of the rod 1.2 is provided with a projection 13 and a re-' duced portion 14:. Rotatably associated with rod 12 is a thimble 15 provided with an internal shoulder '16. A split washer 17 engaging the rod 12 at its reduced portion seats against the shoulder 16 of the thimble 15. The washer 1.7 and the thimble 15 mutually lock each other in position. A screw 18 having symmetrically disposed slots 19 for receiving the wires 6, is placed between them and the thimble 15 which is internally threaded, is then screwed over the screw 18 and the end 8 of wires 6 thereby rotatably securing the receiver fork 10 to the head band. A projection 20 on screw 18 is adapted upon a predetermined movement of rod 12 to engage a projection 13 thereon and thus prevent further rotation.

hen the block 7 is not required the wi re of the head band may be looped at this end in the usual manner and the ends of the rod terminated in the bend S where they will be held securely in the thimble 15 by means of screw 8.

The invention claimed is:

1. A support for telephone receivers com: prising a receiver fork, a thimble rotatably connected to said receiver fork, means engaging said receiver fork to prevent the re.- moval of said thimble, said means and said thimble mutually locking each other, and means rigidly securing said thimble to said head band.

2. A support for telephone receivers comprising a head band, a'receiver fork, and a swivel connection therebet-ween comprising a thimble surrounding adjacent ends of said head band and said fork, said thimble being rigidly secured to said band and rotatably secured to said receiver fork.

3. In a telephone head set, a swivel connection comprising coaxially disposed relative rotatable members, sector shaped projections on said members adapted to engage each other to limit their relative movement and a thiinble secured on one of said 1nen1- hers entirely surrounding said projections.

a. In a telephone head set, 'I-S\VlV(3l connection comprising a hollow cylindrical tl'llll'lblQ, a receiver support inserted in one end of said thiinble, means Within said thilnble to rotatahly secure said support thereto, a head band inserted in the opposite end of said thiinhle, and a closure for one end of said thiinble adapted to rigidly se cure said head band thereto.

5. A head set comprising a head band, a receiver fork and a swivel connection therefor comprising a cup, at rOCl connected to said fork and projecting through the bottom of 15 said cup, a split Washer straddling a recess in said rod and supported on a shoulder within said cup, and a longitudinally slotted screw at one end of said head band cooperating With the cup for holding the re ceiver fork freely attached to said head hand.

In Witness whereof, I hereunto subscribe my name this 28th day of November, A. D.

HARRY R. CLARKE.
