CIRCUIT FOR COIN-COLLECTORS.

Serial No. 300,929.

To all whom it may concern:

it known that I, JAMES L. MoQuMuuE, a citizen of the United States, residing at Chicago, in the county of Cook and State of useful Improvement in. Circuits for Coin- Uelleotors, of which the following is a full, clear, concise, and exact description. My imrention relates to a coin collecting telephone system,

{)ne of its objects is to provide a signaling circuit having contacts adapted to be controlled 9 plurality of coins. v A tum r object of my invention is to provide an improved arrangement of line and cord circuits, by which the operator at the central ollice can provide For the proper disposal coins deposited in the subscribers coin receiving apparatus without waiting for the subscriber to hang up his receiver, thereby relieving the system of drag.

My invention is adapted for use with coin collectors where the dc )osit of one or more coins, as the case may be, is required of the calling subscriber. in order to reliey'e such systems of drag, due to the operator having to wait until the subscriber hangs u his receiver before the coin can be returne to him, in case the desired connection is not established, I have introduced into the cord circuit a relay, which looks the refund battery incircuit with the subscribers line. The circult of the coin controlling magnet is so arranged that soon as the subsc 'ibcr hangs up his receiver, the circuit from the battery is completed through the magnet, which thereupon operates mechanism in the usual manner for properly disposing of the coins.

- Iuu'll describe my invention more partic ularly by reference to the accompanying drawings, which is a diagrammatic view showing a line and cord circuit embodying my invention, and illustrating by means of conventional symbols the apparatus at a subscrib'ers station and at the central ollice.

The cord and line circuit I have chosen to illustrate my invention with, are of wellknown types, and hence a detailed de.scI'i],)--

tion of the familiar featuresthereof isunnecessary. 1

Referring to the drawii'igs, the branch circuit g from the tip side of the line is provided 7 with the usual polarized magnet M for con trolling the disposal of: a coin or coins 7c, ls, deposited by the subscriber In his com rc- .key.

. not Mr qun'ed irom the subscriber and coin l: has

eeiving apparatus. The contact a is normally open, wlnle'contact 1) 1s normally closed. The-coin 0, first deposited, closes contact (t and grounds the branch circuit, Illinois, have invented a certain new and 5 thereby operating signal L at the. central office in the usual manner. The deposit of the second coin 7r, in cases where 'two or more coins are required for connection, opens the contact 7), the branch circuit being then grounded at the subscribers station, through a shunt of contact I), only when the telephone hook is down, since the contact l) in said shunt is otherwise open. Since the de osit ol' the second coin removes the ground rom' the branch line g, the operation of the test key 0 would not close a circuit from the common central ollice battery through the relay 0. The contact 0 is normally open and, unless the relay c is ener ized to close said contact, the test lam Hence the failure of tie test lamp to light f1 is not lighted indicates to the operator that the second pose a drag on the system to require the oporator to wait until the calling party hangs up his receiver before she operates the refund In order to eliminate this drag, a relay 6 has been introduced into the cord circuit. \Vhen the refund lieyfis operated, the circuit from the battcryj" is grounded through contact f The relay 0 which has a winding included in said circuit operates its armature c and closes a locking circuit through contact a". This circuit may be traced from ground through battery f, winding of relay 6, con tact 6*, over the tip side of the line, through thesubscribods set in case its receiver is oil its hook, over the ring side of the line, through relay s, contact 0*, which is closed by relay (1, to ground. In case only one coin c has been deposi l 2d, the circuit over the tip side of the hue would, of course, be groun ed throu h the normally closed contact I), and upon t is operationol' keyf the coin would be immediately refunded by the operation of the mag- In case two or more coins were realso been deposited, the ground through magnet M would be completed through contact b as soon as thesubseriber hangs up his receiver. It is apparent, therefore, that the operator, without waiting for the subscriber to hang upihis receiver, may operate the refund keyf. and thereby provide for the return of the coins to the calling; subscriber without further attention on her part.

Having thus described my invention, 1 claim 1. The combination with a telephone line extending from a subscribers station to a central ollice, of a coin receiving apparatus at the subscribens station, an electromagnct, mechanism operated by the energization of said magnet for disposing of a coin deposited in the coin receiving apparatus, means at the central o'llicc for impressing current upon the telephone line, and means at the subscribei"s station, automaticaltv operated upon the subscriber hanging up his receiver, to apply said current to the electromagnet.
