CLARENCE A. ANDERSON, OF SALINA, KANSAS.

PAY-STATION BOX FOR TELEPHONES.

To all whom it may concern:

Be it known that I, CLARENCE A. ANDER- SON, a citizen of the United States of America, and a resident of Salina, county of Saline, and State of Kansas, have invented certain new and useful Improvements in Pay-Station Boxes for Telephones, of which the following is a specification.

My invention relates to pay station boxes for telephones, and has for its object the construction of an improved form of box for receiving prepayment of telephone charge for a period of time.

In the accompanying drawings: Figure l is a front elevation of the box; Fig. 2- is a rear elevation with the back plate removed to show the interior; Fig. 3 is a section on line 3-3 of Fig. 1 showing a coin receptacle closed; Fig. 4 is a similar section on lines l4l of Fig. 1 showing a coin receptacle not closable when no coin is in it; Fig. 5 is a similar section on lines 55 of Fig. 1 showing how a coin in a receptacle makes it pos sible to close it; and Fig. 6 is a partial plan of the top of the box showing an opening through which the subscriber may deposit money of any kind to meet the next payment due.

In the said drawings A is a back plate which may be secured by screws to the wall or any convenient place, and B is a box secured to said plate by lugs B which pass through suitable openings in the plate A, and by a lock A Fig. 3 shows the bolt of the lock thrown so as to secure the box in and Fig. l shows the bolt withdrawn so that the box may be removed.

The front lower part of the box B is slightly bulged outward as shown at B and inside of this bulge is a shaft O which runs across the entire width of the box. At intervals in the front of the box are cut slots which expose parts of the shaft C, and on the thus exposed portions of the shaft are pivoted or secured a plurality of quadrantshaped coin receptacles D. The front faces of the receptacles D consist of plates D which are secured to the quadrants D and are long enough and wide enough to completely cover the slots in the box B for said quadrant-shaped receptacles.

Each receptacle D consists of two quadrant-shaped metal plates secured together by the front plate D the quadrant-shaped plates being spaced a sufficient distance apart to admit the easy insertion of a coin,

but less than a distance equal to twice the thickness of the coin to be inserted. The coin is inserted in the upper or curved face of the receptacle D when said receptacle is in the position shown in Fig. 5.

A bolt D passes through each receptacle D, and pivoted on said bolt, between the plates which form the side walls of said receptacle, are preferably two or more catch levers E, which are controlled jointly by an inserted coin and by springs E hen a receptacle is open, that is, when it is moved outward on its pivot C, and there is no coin in the receptacle, the spring E normally holds the catch levers E against a pin D in the plates which form said receptacle D. This position is shown in Fig. 4e. IVhen a coin is inserted the levers are pushed back as shown in Fig. 5.

The lower end of each lever E is provided with a bevel-faced catch E and secured in the lower part of the box B is a corresponding bevel-faced catch B IVhen no coin is in the receptacle D the lower ends E of the levers E strike on top of the stationary catch B and the receptacle cannot be closed. hen a coin of the proper size is in the receptacle the levers E are pushed over so that the bevels on the lower end come opposite the bevel on the edge of B In this position the receptacle D may be closed and the catch E will come under the catch B as shown in Figs. 3 and 5. IVhen these catches engage each other in this way, the receptacle D cannot be opened from the outside of the box for the removal of the inserted coin. By opening the box, however, and inserting a tool to push the two levers E back so as to release the catch E the receptacle may be opened and the coin removed.

As far as the operation of the device is concerned, one lever E in each receptacle D is sufficient, but by making two or more such levers in each receptacle the difficulty of operating the device by a wire is greatly increased, in fact, made practically impossible. Thus, by having two levers E in each receptacle, both of which have catches E and each of which has its own spring E no wire inserted into the receptacle can simultaneously operate both levers E unless the wire is of a diameter greater than half of the space between the quadrant-shaped plates which form the walls of the receptacle D. Any wire as large as this would not permitthe receptacle to be closed, and closure of the receptacle is a prerequisite to the operation 3 of the device as will be hereinafter set forth. As a further guard against the use of a small wire with a heavy end, or a wire fastened to a coin for the purpose of withdrawing the coin after telephonic connections have been made, a part D of the receptacle D passes inside of the box B when the receptacle is closed and acts as a shear to cut off any such wire or a string.

Insulatingly supported on the plate A is a contact spring F located between two other contact springs F and F These springs are connected to the wires running from the central office to the local station in such a way that when F is in contact with F telephonic connection between the office and the station is possible, but when F engages F such telephonic connection is impossible. The normal tension of F is to hold it in contact with F and away from F Secured to the shaft C is an arm H having a piece of insulation H on its end adapted to engage the spring F and force it against the spring F and away from F. This occurs when the shaft 0 is in a certain fixed position, but when the shaft is moved from that position the spring F is released and engages F Each receptacle D is provided with a set screw S or other means by which it may be also secured to the shaft. If, with the arm H in the position shown in Fig. 3, a receptacle D be also secured to the shaft G in the position shown in said figure, then if the catches E and B be released so that the receptacle may turn on its pivot, suc'h a movement of the receptacle will cause a corresponding movement of the arm H and the contact F will be released from the contact F Also, if no coin is in the receptacle, the stoppage of E on top of B as shown in Fig. 4, will prevent the arm H from moving far enough to close connection between F and F The device shown in Fig. 1 is illustrated as being of a capacity for the prepayments of five dollars or less for a stated period, as for one month. The four large receptacles are each for silver dollars as the proper size of coin. The next one is for a half-dollar, and the two at the right are for twenty-five cent pieces. If the prepayment sum is two dollars for one month in advance, two large receptacles may be used, or one large one and the three smaller ones. If the prepayment is five dollars then all receptacles are used, but for sums less than five dollars the arrangement is preferably to use as many of the receptacles as possible in making up the required sum. The reason for using as many receptacles as possible in making up the required payment is to increase the difficulty of operating the device with anything other than the required coins. This will be apparent by a little consideration. In the previous description, one receptacle was described as being secured to the shaft G in such a way that the two arms E within the receptacle D must be moved by a coin or its equivalent so that the bevel on E can slide down the bevel on B before the arm H can close the connection between F and F. If now a second receptacle be secured to the shaft C in the same way, a coin must be placed in each of the receptacles so that the arms E in both receptacles may be moved to permit the shaft to be moved to a position in which the arm H will close F and F. If three or four receptacles be secured to the shaft then coins must be placed in all that are so secured; otherwise, the one in which no coin is placed will have the end E striking on B, as shown in Fig. 4, and this will prevent the closing of telephonic connections at F Any receptacle not secured to the shaft may be left in a locked position without affecting the operation of the device as the shaft C may turn freely in the bearing in such receptacle. Inside of the box over the smaller of the receptacles is guard plate G and partition P (Figs. 2 and 5) which provide a separate interior chamber. In the top of the box B over this chamber is a slot K through which money may be placed in the chamber for the next prepayment.

The operation of the device is as follows: Assuming that the subscriber has to pay the flat rate of four dollars per month, three of the large receptacles and the three smaller receptacles are secured firmly to the shaft in the manner described. The remaining large receptacle is left loose on the shaft. With the box B removed from the plate A, the employee who is installing the apparatus pushes back all of the catches E so that they clear the catch B and permit the six receptacles into which coins are to be placed to be opened. For this purpose the employee has a special tool spaced to match the spacing of the receptacles, otherwise he would have extreme difficulty in simultaneously releasing all of the catches E which belong to the receptacles fast to the shaft. The opening of the receptacles secured to the shaft moves the arm H away from the contact spring F and opens the telephonic connection of the station. The box B is then placed on the plate A and locked in position. Either before or after this the station wires are connected in the proper manner to the contact springs and the plate A secured permanently by screws and proper seals to the wall. Before the subscriber can use his telephone he must close these receptacles, and as they are all fast to the shaft he must close all of them at once. To close them he must simultaneously manipulate all of the twelve levers E with their catches E and the only way of doing that is to insert in the several receptacles the proper sizes of coins or their equivalents in slugs. At the end of the month the collector either removes the coins from the receptacles and leaves them open, or collects the next months payment in advance from the sub scriber in other money. Ordinarily it will be the latter which will be done as the subscriber cannot use the telephone again until the required coins are in their receptacles, and the particular change may not always be on hand. In cases of this kind the same coins will remain in the receptacles continuously from month to month. In case the subscriber is liable to be away when the collector calls he may push the next months payment through the slot K into the side chamber. The collector opening the box and finding the money in this chamber simply removes it, leaving the original coins in their receptacles. Upon failing to receive the money in any other way he takes it from the receptacles and leaves them open, the consequence of which, is that telephonic connections to the station are cut off until they are filled again.

A box made in this Way has a certain analogy to combination locks in that it has a combination of devices which must be simultaneously operated by a plurality of coins to permit the telephonic connections of the station to be established, and requires a suitable instrument or key to release these combination devices so that the coins may be removed. The coins, which serve as the key for permitting the telephonic connections to be closed, are inserted from the outside by the subscriber. The key or instru ment for releasing the combination is inserted from the inside after the box has been opened by an ordinary key in the ordinary manner. The coins are therefore doubly locked against unauthorized removal, the second look being a special one requiring a special key to release the combination.
