TELEPHONE-SWITCH.

SPECIFICATION forming part of Letters Patent No. 552,866, dated January 7', 1896.

Application filed April l, 1895. Renewed December 16, 1895. Serial No. 572,336. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE XV. COY, a citizen of the United States, and a resident of Milford, in the county of New Haven and State of Connecticut, have invented a certain new and useful Telephonewitch, of which the following is a specification.

My invention relates to telephony, and particularly to telephone apparatus wherein one or more switches are employed in cutting into and out of circuit one or more of the various elements of said apparatus, such as the callbell, the receiver and the transmitter.

The main object of the invention is to so construct and arrange said parts that one or more of said switches may be operated and, if desired, all the necessary switching may be done through the instrumentality of the transmitting apparatus instead of being done as heretofore by means of the receiver or handswitches.

My invention consists in the combination, with the necessary switching mechanism of a telephone apparatus, of a transmitting appa ratus a part or all of which is movably mounted and adapted in its movement to operate the switching mechanism, and a signal operated by replacing the receiver to warn the user that the transmitting apparatus mustbe moved to a position such as to operate the switching mechanism.

My invention also consists in the combination of a switch for one or more of the circuits of a telephone apparatus, which switch is provided with conducting arms or levers in one of said circuits, and a transmitting apparatus having a movable part for engaging with said arms to connect them electrically.

My invention further consists in the construction, combination and arrangement of parts hereinafter described, and set forth in the claims.

In the accompanying drawings, forming a part of this specification, Figure l represents in side elevation a telephone apparatus embodying my invention. Fig. 2 is a like representation of a modiication thereof. Fig. is a diagrammatic represent-ation of the circuits in my apparatus, a switch mechanism being shown in detail. Fig. i is a modification of the principal parts forming the subject of Fig. 8.

The forms of switch herein shown and the manner of operation by a movable transmitting apparatus or portion thereof may be greatly varied, and several variations thereof form the subject-matter of applications iiled by me March l5, 1895, Serial No. 541,850; April l, 189 5, Serial No.v 544,012, and April 5, 1895, Serial No. 544,655.

In the apparatus as illustrated the general arrangement is on the usual plan and only those features which embody my invention are shown in detail.

A indicates the call-bell, which may be mounted in a suitable box, as B, made to contain the magneto. The latter being of the usual form and arranged in the usual manner is omitted from the drawings.

@indicates the receiver; D, the transmitter; E, the induction-coil, and F the battery in the local circuit. The coil, the battery, and the switches operated by the transmitter are preferably located in the box G, mounted on the back H along with the box B and the transmitter-arm.

For the purpose of doing the switching by means of the transmitter as it is moved into and out of speaking position I have shown in Fig. l an ordinary microphone, preferably of the Hunning pattern, mounted on an arm, as I, hinged to the back H.

In the rst application above referred to the switch mechanism is operated simply by the movable part of the transmitting apparatus operating upon the switch-levers. In this case the switch-levers are connected into the circuits and the movable part of the transmitting apparatus serves to conduct the current from one switch-lever to the other when inserted between them.

As shown in Fig. 3, the switch-lever .l is in elbow form pivoted at the angle and carries a plate insulatedl therefrom, which is intended to form connection between two contacts 5 6, located in the receivercircuit The co-operating lever K is also of elbow form and pivoted at the angle and carries a contact S, insulated therefrom, for engagement with a contact 0, connected to the local circuit 10. These two levers are provided with suitable springs for holding them in firm contact with the movable part of the transmitter when placed between them and for closing the other circuits controlled thereby when said movable part is moved from between them.

In Figs. l and 3 the movable part of the IOO transmitter is the arm I, which is of metal and forms a path for the circuit between the levers J and K, when inserted between them. This path is that of the current through the bell represented as circuit Il, circuits 7 and Il having a common return over circuit l2.

In the apparatus just described I prefer to mount the arm I so that it will remain in any position to which it is moved by the operator. It is then advisable to provide some means for calling the attention of the operator to the fact that he must depress the arm I, after using the telephone, in order that the switch may be placed in the proper position. Iprovide for this by connecting to the local circuit a branch circuit, as 13, in which I locate a buzzer or any suitable signal, as indicated at Il. The circuit I3 has included in it two arms, as IWI N, placed a short distance from each other or separated by any suitable insulation. The receiver C may then be provided with a ring, as O, adapted to pass over both said arms and close the circuit between them, as indicated, though I do not limit myself to this manner of operating the switch in the local circuit.

The operation of this apparatus is as follows: The parts being in their normal condition, as indicated in Fig. 3, the user after ringing up removes the receiver froln its hook, (in this case the arms M N,) which opens the buzzer-circuit at that point. IIe then raises the transmitter into speaking position, which interriilpts the bell-circuit and allows the arm J to bring plate c into engagement with contacts 5 and (j, thereby closing the receivercircuit and arm K to bring plate S into engagement with contact 9, thereby closing the local or transmitter circuit. Then, when through speaking, the receiver is placed upon its support,thereby closing the circuit through the buzzer, the sounding of which warns the user that he is to press the arm I down between the levers J and K, which cuts out the receiver, cuts in the bell and breaks the circuit of the buzzer and transmitter at 9.

In the modification illustrated in Figs. 2 and at the transmitting apparatus is shown consisting of a microphone located upon the back II, as indicated at D', and has a iiexible tube, as I', leading thereto,which terminates in an ordinary mouthpiece, (indicated at P.) About this tube is placed a collar of conducting material, as indicated at Q. The receiver-switch in this modification is the same as in Fig. 3, and the bell-circuit is through the collar Q, forming a part of the movable portion of the transmitting apparatus. The local circuit in this construction is made and broken by the movement of the receiver-hook R, as indicated. The part co-operating with close.

ing position, thus breaking the bell-circuit and allowing the plate :c to be brought into engagement with the contacts 5 and 6, thereby completing the receivercircuit. After speaking the receiver is hung up, breaking the transmitter-circuit, and the tube I' is dropped or placed in position of rest between the lever J and the bracket K', thus opening the receiver-,circuit and closing the bell-circuit.

The arm I may obviously be loosely mounted, so that after use it will fall into place between the levers J and K, but Iprefer to have is fixed, so that it must be moved positively from one position to the other. If, however, the user desires to give it an independent movement its pivot may be provided with a thumb-screw 14C, by which said arm may be made to move freely and by which, when desired, it may be made to remain in any position to which it may be moved.

Many changes in construction, combination and arrangement of the elements of my apparatus as above set forth may be made without departing from my invention.

IVhat I claim as my invention isl. In a telephone apparatus, the combination with switch mechanism therefor, of a transmitting apparatus movably mo unted for the operation of said mechanism, and a signal, operated by replacing the receiver, to warn the user to move the transmitting apparatus into switching position, substantially as set forth.

2. The combination with the switches controlling the bell, the receiver and the local circuits, of a transmitting apparatus having a movable part which when in normal position operates said switches, a signal in a branch of the local circuit, and a switch in said branch closed by hanging up the rcceiver.

3. The combination with the pivoted switch levers of conducting material located in the bell circuit, of a switch in the receiver circuit operated by the movement of one of said levers, a switch in the local circuit operated by the movement of the other lever, and a transmitter apparatus having a movable conducting portion resting in normal position between said levers for the purpose set forth.

4.-. In a telephone apparatus, the combination with switch mechanism therefor, of a transmitting apparatus movably mounted for the operation of said mechanism, a signal, operated by replacing the receiver, to warn the user to move the transmitting apparatus into switching position, and a switch operated by the transmitting apparatus to stop the signal, substantially as set forth.

- Signed at New York, in the county of New York and State of New York, this 29th day of March, A. D. 1895.
