Serial No. 475,962.

To all whom it may concern:

Be it known that I, HOWARD FORDE HAN- sELL, Jr., a citizen of the United States, re-

siding at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Telephone Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification. The object of my invention is to provide a bracket, capable of attachment to the ordinary desk telephone stand, for sustaining the receiver and transmitter normally in the position that they occupy when in use; also to so construct the attachment that the center of gravity of the telephone stand will be approximately over the center of its base so as to impart stability to the stand and minimize the chance of accidental overturning; also to so construct the attachment that no part thereof need be upheld by the hand while connection is established, leavin the user free to use both hands either whi e conversing, or while waiting for connection to be established, or while waiting for a party after connection is established, or in case he desires to leave the tele hone temporarily while connection is established; also to so construct the attachment that it may be adjusted to apply the receiver to either ear to suit any particular user; also to so construct the attachment that the opening and closing of the circuit may be effected without any manipulation of the receiver or of the imme diate support therefor; also to so construct the attachment that the same may be readily applied to the ordinary desk telephone at a very slight expense and without any interference with the wiring or electric contacts or other internal mechanism of the telephone.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a front view of a telephone stand embodying my invention. Fig. 2 is a top view of same. Fig. 3 is a section on line 33, Fig. 2. Fig. 4 is a artial view of a telephone stand, showing t e form of my invention.

a is the base and Z; the post of an ordinary portable telephone stand.

c shows a common type of switch lever -having a hook at its outer or free end for supporting a receiver when the telephone is not in use.

The top end of the post is forked, and between the forks is ordinarily pivoted the transmitter.

In my invention the receiverR and transmitter T are supported on opposite ends of a bracket d-ewhich, between its ends, is confined between the forks of the post I).

The bracket comprlses three arms, which are, in effect, sectlons of a single long arm;

To apply the bracket to the ordinary telephone 7 the intermediate arm d, which extends be-' Projecting from the extreme end of the V rear arm 6 of the bracket is a threaded pin t,

on which the transmitter arm T is slipped, the

transmitter being held in position by means of a nut j.

The outer end of the arm f is bent so as to extend forwardly, and secured thereto is the flanged end of a circular-shaped holder is of resilient material, which receives and supports the receiver R. To secure the holder k to the armf, the former is slotted transversely, and a headed bolt m extends through the slot into a threaded hole in the armf. This enables the receiver-holder lc to be adjusted to the desired angle. 7

It is obvious that if he nut g and bolt h be removed, and the bracket reversed and fastened in that position, and the receiver holder readjusted, the telephone will be ar ranged so as to enable the other car to be applied to the receiver.

The switch lever 0 shown in Figs. 1 and 2 is of that common type that is raised by means of a spring n engaging a projection 0 on the lever and depressed by the weight of the receiver. To normally hold the lever c depressed, I provide a resilient clamp p, one end of which partly encircles the post I), while near its other end it is provided with a U-shaped bend normally engaging the outer face of the projection 0 and thus pressing the projection toward the post I) in opposition to the spring n- To release the switch lever, the outer end of the clamp is pressed forwardly, unlocking the projection and allowing the spring to act thereupon to lift the lever c.

The construction of the switch lever controlling device may be varied to suit different types of switch levers. In the type shown in Fig. 4, which is unprovided with a depending projection, I suspend a lever s from one end of one arm thereof. The lower edge of the horizontal arm of lever s is provided with a notch a and an adjacent cam 12, the cam normally engaging the switch-lever" c and holding it down. By raising the free end of the horizontal arm of lever s, the switchdever c rises and settles in the notch o and remains there until the free end of the horizontal arm of lever s is depressed. I

imiile I have hereinbefore recitedcertain objects which it is sought to attain and which are in fact attained by the construction illustrated and hereinbefore described,

it will be understood that the invention is not necessarily limited to a structure having all of such advantages so long as the same possesses the essential characteristics defined in the claims.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a telephone, the combination with an upright support, of an elongated bracket or arm fixedly secured thereto between its ends and whose said ends overhang said suport on opposite sides thereof, a receiver edly secured at one end of the bracket and a transmitter fixedly secured at the other end thereof.

2 In a telephone, the combination with an upright support, of a bracket comprising an intermediate arm attached between its ends to the support, a rear arm extending transversely in one direction from the rear of the intermediate arm, a front armextending transversely in the other direction, and forwardly, from the front of the intermediate arm, a transmitter supported from the sec ond arm, and a receiver supported from the third arm.

3. In a telephone, the combination with an upright support, of an elongated bracket or arm supported thereon between its ends and extending substantially horizontally, a forwardly extending transmitter supported at one end of the bracket, and a transversely extending receiver supported at the other end thereof.

4. In a telephone, the combination with an upright support, of an elongated bracket or arm supported thereon between its ends and extending forwardly in one direction from its point of support and transversely in the other direction from its point of support, a transversely extending receiver supported on said forward extension and a forwardly extending transmitter supported on said transverse extension.

5;. In a telephone, the combination with an upright support, of an elongated bracket or arm supported thereon between its ends and extending rearwardly in one direction from its point of support and transversely in the other direction from its point of support, a forwardly extending transmitter supported on said rearward extension and a transversely extending receiver supported on said transverse extension.

6. In a telephone, the combination with an upright support, of an elongated bracket or arm supported thereon between its ends and extending rearwardly and transversely in one direction from its point of support and forwardly and transversely in the other direction from itspoint of support, a forwardly extending transmitter supported on said rearward and transverse extension and a transversely extending receiver supported on said forward and transverse extension.

7'- In a telephone, the combination with a base, a post projecting upwardly therefrom, and forks at the top of the post, of an elonated bracket or arm extending between said forks, and attached thereto, and a transmitter and a receiver supported at opposite ends ofthe bracket.
