SPECIFICATION forming part of Letters Patent No. 675,378, dated June 4, 1901. Application filed March 15, 1901. Serial No. 51,839. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES E. EGAN, a citi-' zen of the United States, residing at Durham, in the county of Durham and State of North Carolina, have invented certain new and useful Improvements in Pay Telephones, of which the following is a specification.

My present invention pertains to pay-telephones, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings,wherein Figure 1 is an elevation of so much of the front portion of a telephone as is necessary to an understanding of the invention; Fig. 2, a similar view, the door or closure being open; Fig. 3, a vertical sectional view; Fig. 4, a horizontal sectional view; Figs. 5 and 6, sectional perspective views showing the apparatus in different positions, and Fig. 7 a diagrammatic view illustrative of the circuits of .the instrument.

The object of my invention is to provide a simple and efficient means wherebya coin introduced into the instrument to pay the toll may, if the party is not to be had, be returned to the depositor, the return of the coin being under the joint control of the central office and the user of the telephone.

The invention is illustrated in connection with an ordinary telephone, and it is to be understood that it is susceptible of use in connection with any type of instrument or any arrangement of circuits.

Referring to the drawings, A indicates the frame of the cabinet or casing, and B the usual door or closure, having an opening 0, in front of which is attached a frame or casing D, preferably rectangular in form and closed to access from without. A coinway or slot E, open at its upper end, is provided intermediate the door and the shell or casing D and extends down past the opening 0, as best indicated in Figs. 2, 3, and 4. In line with the lower end of the coinway is mounted a receptacle F, designed to receive the coin when the particular subscriber wanted cannot be reached. The inner wall G of the coinway is provided with an opening H of a size somewhat larger than the diameter ofv thecoin to be used to pay toll for use of the instrument. In the opposite wall I of the coinway there is formed an opening J,through which extends a head or plunger K, said head or plunger standing normally across the coinway, as indicated in Figs. 3 and 5. The plunger is carried by a stem or rod L, which in turn is connected to a cross bar or member M, the outer ends of which are connected to rods N N, which pass through openings formed in the guide or supporting plate 0, secured to the inner face of the door. The inner ends of these rods are connected to a cross bar or member P, in which is adjustably mounted a threaded rod or stem Q, having lock nuts R mounted thereon, which serve to limit the movement of the frame composed of the members M, N, N, and P in one direction by coming in contact with the face of the cross-bar or supporting member 0, as best indicated in Fig. 3.

A rocker-shaft S is mounted below the frame just described, and an arm T extends upwardly therefrom and comes in contact with the cross-bar P. A second arm U is likewise formed upon or attached to the rocker-shaft S and extends out horizontally therefrom and passes beneath the body of the receiver-hook V, so that when the receiver is hung up its weight will, acting through the member U, rocker-shaft S, and arm T, draw the frame inwardly into the position indicated in Fig. 8. A spring W tends to move the frame outwardlyinto the position shown in Fig. 6, withdrawing the plunger K from the coinway. The spring comes into action when the receiver is lifted from the hook. In other words, the weight of the receiver will overcome the action of the spring and normally hold the parts in the position shown'in Fig. 5. A second opening X is formed in the forward wall I of the coinway below the opening J, and extending through this opening into the coinway is a finger Y, attached to the armature Z of a magnet a. The armature is carried by the upper end of an arm 6, which is pivoted at its lower end to a suitable support a, said support in turn serving to hold the magnet in its proper position.

Secured to the door or to suitable conductin g-plates d are spring-arms 'e f, which extend forwardly past each side of the coinway and are so proportioned and arranged that when a coin is dropped into the coinway it will bridge the space between said spring contact-arms, and thereby complete the circuit through the same and through suitable connections, which will now be described.

Upon reference to Fi 7 it will be seen that the spring contact-arm e is connected to line 1, which leads to a binding-post or main-line terminal 2, the opposite end of said line 1 passingto one member 9 of a circuit-closer h, mounted on the shell or casing D. Arm 1'' is by line 1 connected with the magneto-generator 3, which in turn is connected'through a line 4 to a contact plate or finger 5, arranged in the path of the inner end of the hook V, making contact therewith when the receiver is on the hook and completing the circuit through a spring 6 and a line 7 back to the main-line terminal 8. The bell 9 is included between' the lines 1 and 7.

One side of the magnet a is connected to the second terminal 1 of the circuit-closer 71, while the opposite side of the magnet is grounded through a line 10. The telephonecircuit is shown in dotted lines in Fig. 7, and when the receiver is lifted from the hook said circuit is completed through spring contactplates 11 and 12.

Aswitch or cont-act-closerj is placed in the main line under the control of the central office. Normally the generator-circuit is open and is closed by the deposit of a coin therein, as indicated in dotted lines in Fig. 3 and in full lines in Figs. 5 and 7. The coin, as will be seen upon reference to Figs. 3 and 5, is held up by the plunger or ejector K. After the generator has been operated, and the central office thereby called, the user of the telephone lifts the receiver from the hook and in so doing permits the spring IV to come into action, thereby moving the frame and withdrawing the plunger from the coinway, permitting the coin to drop down and rest upon the finger Y, which extends inwardly through the opening X. (See Fig. 6.) If the central office can obtain the person desired by the user, the main-line circuit is closed in the usual manner. After the conversation is terminated the user hangs the receiver on the hook and in so doing rocks the lever and draws the frame inwardly, causing the plunger or ejector K to knock the coin off from the supporting member Y through the opening II into the box. Should it happen, however, that the person desired cannot be reached, the central office will so inform the user, at the same time closing the contactj, while the user operates the contact-closer h, thereby energizing the magnet a, causing the attraction of the armature t' and the withdrawal of the supporting member or finger Y from beneath the coin, allowing the coin to pass down through the coinwayinto the receiver F.

It is manifest that a different arrangement of circuits maybe had in connection with the mechanism described, and I do not therefore desire to limitfmyself to the inclusion of the devices in the generator-circuit. It is also conceivable that the invention may be modified as to details of arrangement without departing from the spirit thereof, and the broader claims are to be construed accordingly.

Having thus described my invention, what I claim is 1.
