UNETED STATES DAVID MORTIMER MILLER, 01? BROOKLYN, NEW YORK, ASSIGNOR TO CHARLES POLLACK, OF BROOKLYN, NEW YORK.

CIRCUIT-CONTROLLING TELEPHONE-RECEIVER SUPPORT.

Application filed March 18, 1921.

To all whom it may concern:

Be it known that 1, DAVID MORTIMER MILLER, a citizen of the United States, and

a resident of the city of New York, borough The object of the invention is to provide a new and improved circuit controlling telephone receiver support arranged to permit the user of the telephone to swing the support with the receiver attached thereto from normally folded, inactive position alongside the telephone standard upward into an angular active position with the receiver in hearing relation at one ear of the person talking at the time into the transmitter.

Another object is to close the telephone circuit on swinging the support from the folded position into extended position for the transmission of messages between two parties.

Another object is to permit the user of the telephone the free use of both hands for writing or other purposes.

Another object is to permit of conveniently and quickly attaching the support to the telephone standard as now generally constructed.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the views.

Figure 1 is a side elevation of the improved circuit controlling telephone receiver support with the parts 1n extended or listening position;

Figure 2 is a front elevation of the same with the parts in folded, inactive position;

Figure 3 is an enlarged sectional rear ele- Serial No. 453,329.

vation of the connection between the telephone standard and the swing arm carrying the receiver; and

Figure 4 is a rear side elevation of the pivotal end of the swing arm.

The receiver support is shown applied to a desk telephone of usual construction such, for instance, as more fully shown and described in the Letters Patent of the United States, granted to Charles L. Boyze on September 13, 1904, No. 77 0,157 for a telephone desk standard.

The telephone desk standard comprises a base 10 and a hollow standard or casing 11 terminating at its upper end in a cap 12 provided with a pivot 13 on which is mounted to swing the transmitter 14 in the usual manner. Within the hollow standard or casing 11 is mounted the usual switch mechanism of the telephone circuit and this switch mechanism is provided with an actuating lever 15 extending through a slot in the standard or casing 11 to project on the outside thereof and terminating in a fork 16 adapted to support the usual receiver, which, however, in this case is not used. It is understood that the switch lever 15 is spring-pressed and is normally held in a lowermost position against the tension of its spring by the weight of the receiver to hold the telephone circuit open, and when the receiver is removed from the fork 16 the switch lever 15 swings upward into position to close the telephone circuit for the transmission of messages in the usual manner.

The receiver support is applied to the telephone standard by the use of the bolt 13 (see Figure 3) and is arranged as follows: A bell-shaped bracket 20 is fastened to one side of the cap 12 by the bolt 13, as plainly shown in Figure 3, and on the mouth of this bracket 20 is secured by screws, rivets or other fastening means 21 a cap 22, on the outer face of which rests the rim 23 of a cupshaped pivot member 24 of a swing arm 25 carrying at its free enda receiver 26 of any approved construction. The member 24 is mounted to swing on a bolt 30 extending centrally through the member 24 and the 22 to maintain the swing arm 25 in any po- 1 J sition it may be swung into by the user. The swing arm 25 is provided adjacent its pivot member 24 with a cam 35 adapted to engage the fork 16 of the switch lever at the time the arm is swung from raised active position, as shown in Figure 1, clownward into the folded inactive position shown in Figure 2. Thus when the swing arm 25 moves into folded position the cam swings the switch lever 15 downward, hence the telephone circuit is opened. lVhen the swing arm 25 is swung upward from the position shown in Figure 2 into the position shown in Figure 1 then the cam 35 releases the fork 16 of the switch lever 15 thereby allowing the latter to swing upward by the action of its spring to close the telephone circuit. The arm 25 is of such a length that the receiver 26 is located at one ear of the person making use of the telephone at the time, that is, having its mouth in speaking relation with the transmitter 1 1.

From the foregoing it will be seen that by the arrangement described it is only necessary for the user to swing the arm 25 "from the folded position shown in Figure 2 upward into the position shown in Figure 1 to close the telephone circuit and to hold the receiver 26 in close proximity to one ear of the person making use of the telephone at the time. When the user is through, the arm 25 is swung downward back to folded position thereby causing the cam 35 to actuate the switch lever 15 to open the circuit as above described. The usual cable containing the circuit wires for the receiver 26 extends from the upper end of the cap 12 and passes through an opening 41 formed in the bracket 20 to then pass through a slot 12 formed in the cap 22 to enter the arm 25 which is made hollow or tubular for the purpose. The cable 40 then connects with the receiver 26 in the usual manner. It will be noticed that the cable &0 is nractically concealed and is hence completely out of the way of the person making use of the telephone, and the cable does not interfere in the slightest with the movement of the arm 25.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A telephone including a supporting stand ard, a transmitter mounted at the upper end of the standard, a circuit controlling lever fulcrumed in the standard, means normally urging said lever to close the circuit, a bellshaped bracket spaced from the upper end of the standard, a cup-shaped pivot member secured upon the outer end of the bracket, an arm carried by the pivot member, a receiver at the free end of the arm, means carried by the arm engageable with the lever to open the circuit as the arm is swung downwardly, means normally causing friction between the pivot member and bracket to retain the arm in any desired position, said means comprising a bolt pivotally connecting the pivot member and bracket, and a coiled expansion spring around the bolt urging the bracket and pivot member into frictional engagement with each other.
