TELEPHONE ATTACHMENT.

Applicationfiled May 19,

users ear when he is talking into the transmitter or in a position where it is out of the way when the telephone is not in use.

The primary object of the invention is the provision of an attachment of the foregoing nature incorporating mechanism for depressing the receiver hook when the receiver is moved from operative to inoperative position and permitting the hook to rise uponmoving the receiver-to operative position.

Further objects are the provision of a comparatively simple device of the afore said characterthat'may be readily attached to telephones of standard design; is very convenient of use; positive of action; not likely to get out of order; and easily and quickly adjustable to alter the relation of receiver and transmitterto fit the requirements of different individuals.

I attain the foregoing objects, and others which will become apparent as this description proceeds, in the attachment illustrated in the accompanying drawings wherein Fig. 1 is a side elevation of a telephone equipped with my improved receiver supporting attachment; Fig. 2 is a fragmentary side elevation showing the receiverin operative position; Fig. 3 is a front elevation ofthe parts shown in Fig. 2; Fig. 4 is a plan view with the receiver omitted and a part of its supporting arm broken away; Fig. 5 is a detail illustrating the nature of the pivotal connection between the receiver supporting arm and bracket; and Fig. 6 is a sectional detail on the lines 66 of Figs. 1 and 4.

The telephone in connection with which my attachment is herein illustrated is of the stand type and comprises a base 1, stem 2, and transmitter 3. The receiver supporting hook 4 extends laterally from the upper end of the stem 2, and, in accordance with prevailing practice, is so connected to the Specification of Letters Patent.

switch of the talking circuit as to cause said circuit to be established when the hook is raised by its actuating spring and broken when the hook is depressed.

My attachment includes a supporting plate 10 secured to the telephone, in the present instance by being provided with a semicircularportion 10 which passes about one side of the stem 2, and a correspondingly shaped clip 11 that is engaged about the opposite side of the stem and has its ends connected to the adjacent ends of the portion 10"-, by screws 12. A bracket 14 is pivotally connected to the upper end of the supporting plate 10, as by means of a bolt 15 (see Fig. 6) thatextends through the respective bosses 16 and 17 of the plate and bracket, a nut 18 being applied to the end of the bolt where it protrudes beyond the boss of the plate. v The bracket 14 may be adjusted about the bolt 15 to any angular position with respect to the plate 10, and to securely hold it in any adjusted position I employ a screw 20 which, in the present instance, extends through a segmental slot 21in the circular flange 22 of the bracket 14 and is threaded into the plate 10, the screw having a washer 23 inserted between its head and the adjacent face of the flange. By loosening the screw the bracket 14 may be swung to desired position where it may be securely held by tightening the screw. The outer end of the bracket 14 is bifurcated and has pivoted to it, by means of a screw 25, or the like, the inner end of the receiver supporting arm 26. referring to Fig. 5, the nature of this con nection prevents the arm from swinging beyond approximate alignment with the bracket 14, the straight end portion 27 of the arm engaging a part of the bracket. The outer end of the receiver supporting arm is equipped with a clamp portion 28 which cooperates with a clip 29 to hold, through the instrumentality of the screws 30, the receiver 31.

35 is a finger that is pivoted upon the bolt 15 and extends out over the receiver hook. A link 36 has one of its ends pivotally connected at 37 to a part of the receiver supporting arm 26 near its inner or pivoted end, the link being spaced or oil-set from the arm to prevent interference with the end of the bracket 14, or the head of the screw 25. At its lower end, the link 36 is slotted to receive a stud 38 which extends As will be seen upon laterally from the finger 35.

For convenience in assembling the slot, which is designated 39, opens through the end of the link 36 although, after the parts are assembled the ends on each side of the slot are pinched together somewhat to prevent the with drawali of" the stud from the slot.

In setting up the attachment, the supporting plate 10 may be clamped to the stem 2 of the telephone in such a position as to cause the receiver to be properly disposed laterally with respect to the transmitter, and the bracket 1. L may then be adjusted with respect to the supporting plate to bring the receiverto its proper elevation, after which the screw 20 is tightened to securely hold the parts in such position. lVith the receiver thrown backward as shown in Fig. 1, it throws downward the linger 35, through the intervention of the link 36, to depress the receiver hook and break the talking circuit. IVhen it is desirable to use the telephone, the receiver is swung forwardly into the position shown in Figs. 2 and 3 and by the swinging of the receiver sup porting arm 26, the link 36 is drawn upward to elevate the finger 35 and permit the receiver hook 4 to rise, thereby to establish the talking circuit.

1 I have shown a brace 40, clamped to the stemv 2 immediately above the base 1, the same comprising legs 41 which flare outward beyond the base and bear upon the supporting surface to prevent oventilting of the phone by reason of the added weight of, the attachment to its upper end.

Having thus described my invention, what I claim is:-

1. In a telephone attachment of the characterset forth, the combination of a bracket secured to the telephone, a receiver supporting arm pivoted to the bracket, and adapted to be swung in a vertical plane from a position forward of-the telephone to a position rearwardly thereof, a finger extending across the receiver hook and pivotally sup ported to the rear thereof, and a link directly connecting parts of the receiver supporting armand the aforesaid finger adjacent their pivots.

2. In a telephone attachment of the character set forth, the combination of a supporting. member secured to the stem of the telephone, a. bracket adjustably connected thereto, a receiver supporting arm pivotally connected to the bracket and adapted to be swung through a vertical plane, a finger pivoted to the supporting member and located in operative relation to the receiver,

hook, and connections between the finger and receiver supporting arm whereby said finger is depressed when; the receiver supporting arm is swung from operative to inoperative position.

3. In a; telephone attachment of the character set forth, the combination of a supporting member secured to the telephone, a

bracket pivoted thereto, means for securing said bracket to the supporting member in any desired position, a receiver supporting arm pivoted to the bracket, a, finger pivoted to the supporting member and disposed in operative relation to the receiver hook, and a link directly connecting parts of the finger and the receiver supporting hook whereby the swinging of the arm through a vertical plane fromoperative to inoperative position a will depress the finger. I

In testimony whereof, I hereunto aflix my signature.
