TELEFHUNEE ATTACZHWIElNITi SPECIFIUATION forming part of Letters Patent No. ?94,016, dated July 4, 1905.

Application filed March 2, 1905. Serial N0- 248,101.

1'0 (ti/Z whont it rim/y concern:

lie it known that l, FRANK F. Howe, a citizen oi the United States, residing at Marietta, in the county of l/Vashington and State of Ohio, have made certain new and useful Tmprovements in Telephone Attachments, of which the following is a specification.

My invention is an improvement in telepl'ione-rcceiver supports; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

in the drawings, Figure 1 is a perspectiveview of my invention as in use. Fig. 2 is a cross-sectional view on about line 2 2 of l i g. 3. 3 is a side elevation of the device. Fig. 4 is a top plan view thereof. Fig. 5 is a detail cross-section on about line 5 5 oi? Fig. i. Fig. 6 is a detail view of the spring for actuating the receiver-clamp, and Fig. 7 shows the application of the invention to a switchlfork ar 'anged above the rocking lever.

lln carrying out my invention I provide a main frame having a base-plate A and forwardly-projecting lugs A, between which is pivoted vertically at A the inner end oi a latorally-prejecting arm B, which is preferably made tubular and is spring-pressed to the position shown in Figs. 1, 2, and 4, in which it operates upon a rocker to close the switch oi the telephone and cutout the receiver. When, however, the arm B is moved from the position shown in Figs. 1, 2, and 4: to the dotted line position shown in lhig. 2, it moves out ol engagement with the rocker and permits the telephone-switch to open. In spring-actuating the lateral arm B it is n-eferred to coil a spring U about the pivot-rod A and arrange said spring to bear at one end against the rod l3 and at its other end against the main frame in order to properly actuate the rod .13 as desired. This swinging rod B may be termed a carrier, as it supports, through intermediate mechanism, the receiver, and this swinging carrier is arranged to operate the rocker presently described to close the switch of the telephone and cut out the receiver when the latter is not in use.

The receiver D is held by the clamp E, having the projecting shank F booked at f to en gage with a pin G, extending across the socket H at the outer end of the swinging carrier, the carrier being preferably made in sections so it can adjust longitudinally at l. and pivotally at J, as will be presently described. The hooked shank F may be rocked on its connection with the pin G in securing the desired adjustment oi the receiver to the ear, and to hold it yieldingly in such connection 1 provide a spring for securing the hooked shank in engagement with the pivot-pin This spring is preferably in the form of a rod b1, secured at one end KT in a groove L in the under side of the box or socket H, the outer end of said groove being flared, as indicated at L in Fig. 5, to permit the lateral play of the spring l Land the free end if of the spring K bearing against the shank Ii and pressing the same into interlocked engagement with the bolt G, as will be understood from Figs. 4c and 5 ol the drawings. This construction permits a slight rocking movement of the receiver on the bolt (1} as a pivot and at the same time holds the said receiver yieldingly in connection with said bolt and permits its removal whenever desired for any purpose.

The swinging arm is made oi the inner tnbular section slotted at l to receive a pin Ml, projecting laterally from the intermediate section iii, the outer end of the intermediate section M being pivoted at .l to the inner end ol the outer section N of the swinging arm, this outer section N carrying the bolt i, on which. the receiver-clannp is adjustably secured by means of the spring be'l'ore described. This construction of swinging arm permits the receiver to be swung laterally with the arm and also permits a slight tilting movement on the bolt Ur independent oi the swinging move ment of the arm, permits the receiver to be moved out or in by the sliding of pin M in the slot T, and also permits the receiver to be raised and lowered on the pivot J, as will be understood from the drawings.

The rocker O is pivoted at O to a bracket P, extenrfling outwardly from the main frame and n'elt'erably deflected at P, so its outer end P will underlie the inner section of the swinging arm in the normal position oi. the parts, as shown in Figs. 1, 2, and 4:. The rocker (I) extends across the bracket P and is in the form of a lever connected at its free end O with the switch-fork of the telephone, so that the rocker 0 when its free end O is depressed will move the switch Q downwardly and close the switch of the telephone and cut out the receiver. As shown, the rocker O has an inclined surface 0 against which the swinging arm operates when moved from the position indicated in dotted lines Fig. 2 to the full-line position in said figure and so depresses the free end 0 of the rocker in such manner as to close the switch.

In operation when the parts are in the position shown in Figs. 1, 2, and at and at rest the receiver is cut out by the closing of the switch Q. hen, however, a person uses the phone, the swinging carrier will be moved laterally from the position shown in Fig. 2 to the position indicated in the said figure, and the rocker will be released, and the receiver will be cut into circuit, so the phone can be used as desired.

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

1. A telephone attachment substantially as herein described, comprising a main frame, a bracket projecting therefrom, a rocker extending transversely of the bracket and pivoted thereto and adapted for connection with a telephone-switch, a swinging arm pivoted to the main frame, and a spring for actuating said arm normally to position to operate upon the rocker to close the switch, said swinging carrier comprising an inner section, an intermediate section telescoping in the inner Section, an outer section pivoted at its inner end to the outer end of the intermediate section and provided at its outer end with a transverse bolt, the receiver-clamp having its shank detachably engaged with said bolt, and the spring for pressing said shank into engagement with the bolt, substantially as set forth.

2. The combination in a support for telephone-receivers, of a rocker for connection with a telephone-switch, and a laterally-swin ing spring-pressed carrier movable normally to position to operate the rocker to close the switch and adapted to support a receiver, one of said parts, the rocker and carrier, having an inclined surface for engagement with the other part, substantially as set forth.

3. The combination of a main frame, having a laterally-projecting bracket, a swinging carrier connected with the main frame, and movable laterally over the projecting bracket, and a rocker pivoted to the bracket and arranged between the same and the swinging carrier for engagement and operation by the latter, substantially as set forth.

4. The combination with a receiver-clamp having the projecting hooked shank, of a carrier having a bolt adapted to be detachably engaged by said hooked shank, and a spring pressing said hooked shank into engagement with the bolt, substantially as set forth.

5. The combination of the main frame, the bracket projecting therefrom, the rocker pivoted to the bracket and extending transversely across the same and having an inclined surface for engagement by a swinging carrier, and the swinging spring actuated carrier, movable laterally, into and out of engagement with the inclined surface of the rocker, substantially as set forth.
