To all whom it may concern.-

Be it known that I, HENRY G. SWEENEY, a citizen of the United States, residing-in Ohicago, in the county of Cook and State of Illinois, have inventedanew and usefullmprovement in Toll-Collecting Apparatus for Telephones, of which the following is a specification.

This invention relates to that class of tolltelephones which are adapted to receive coins of several different denominations in pay-- ment for use of the telephones and to signal to the attendant at the central office the amount of the coin deposited, so that she may know to what service the patron is entitled.

The object of the invention is to providea very simple coin controlling and signaling mechanism adapted to use with coins of different sizes which shall be reliable in its action.

The nature of my improvement is fully disclosed below and also illustrated in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section of my invention. Figs. 2 and 3 are sections on the lines 2 2 and 3 3, respectively, of Fig. 1. Fig. 4: is a partial plan. Fig. 5 is a horizon-' tal section. Fig. 6 is also a horizontal section showing the under surface of the top of the box in which the mechanism is located. Fig. 7 is an enlarged side view of the gearing employed, and Fig. 8 a vertical section of one of the coin-chutes.

In said drawings, A represents a box or case in which the toll collecting and controlling mechanism may be located and which is usually supported in close proximity to the telephone with which it is used. The person desiring to use thephone inserts acoin of a denomination corresponding with the toll charged for the service desired in one of the slots B or C. If it is a dime, he inserts it in slot O and it falls onto one end of;a lever O, pivoted at O and carrying a-weight O at its other end, and also carrying upon its Weighted end a depending pin 0 which enters a recess in a sliding bar 0 and normally locks the latter. This bar extends to the outside of the case and formsa push-bar to be oper ated by the patron. Behind the bar is a contact-spring 0 which is electrically connected to the circuit-wire D, and the bar is electrically connected to a buzzer or other signaling device D, also connected in the circuit by wire D The coin-receiving end of the lever O is slotted immediately belowchute O, as seen at O and such slot is normally shortened by the latch 0 pivoted to the lever at O sufficiently to enable the lever to arrest the coin. The latch also has a right-angled projection 0 adapted to be engaged by the upstanding pin 0, carried by the push-bar. A spring 0 holds the latch in its normal position, and a spring C returns the push-bar to its original position after the impulse given it by the patron.

The operation so far as chute O is concerned is as follows: When a patron deposits his dime in chute O, (which, by the way, is not adapted to receive any other coin,) it drops ontoand is arrested by lever O and overcomes the gravity of weight 0 so that'the lever swings sufliciently to release the pushbar from pin O". The patron is now at liberty 'to operate the push-bar, and in so doing the push-bar meets the spring 0 and establishes the electric circuit through the buzzer, so that the proper signal is given at the central station to insure the connecting of the phone with the subscriber desired. In the same operation the patron also secures the release of the coin from the lever, the pin O swinging the latch away from the slot in the lever, so that the coin is given sufficient room to drop through the lever into the receptacle below.

For coins of other denominations than ten cents I employ a variable coin-chutc-tht is to say, a chute one side of which is adjustable and must be adjusted by the purchaser before insertion of the coin. My preferred construction of this chute is that illustrated. The mouth of the chute is adapted to admit a coin of the largest size andis provided with a slide 13, adapted to reduce the width of the mouth to agree with the diameter of the coin to be inserted. This slide is operated by the patron before inserting the coin through the medium ofa lever B pivoted atB and connected by a screw or pin 13 to a plate B located below the top of case A, such pin moving through a slot B in said top and the plate being made rigid with said slide. The lever is provided with a knob 13*, so that it maybe easily operated, and is preferably made of spring metal,so that thepin B ,carried upon its free end, may be made to engage the positioning-holes Win the segmental indicator-plate B automatically when the lever is moved over such indicator-plate. I not only provide these means for regulating the width of the mouth of the slot to accord with the diameter of the coin, but I also provide further safeguards adapted to prevent the sending of a signal to central station indicating the payment of a large coin when in fact an inferior one has been inserted. For this purpose I provide at the foot of the inclined portion 13 of the chute a coin-arresting frame B pivoted upon ahorizontal pivot B and provided with a slot I3 ,into which the coin enters and by which it is caught. One end of this slot is formed by a slide I3, and such slide is connected to the plate B so as to move in unison therewith, by a vertical arm or lever B rigid with the plate and engaging at its lower end a pin B", projecting laterally from the slide, which is perforated for this purpose. By this slide the slot I3 is always maintained at alength corresponding to that of the mouth, the changes, if any, being made simultaneously and being equal in extent in both. It will be seen that the slot 13, being somewhat less in length than the diameter of the coin, is adapted to momentarily arrest the coin and retain it a sufficient time to cause the swinging of frame B on'its pivot. This swinging is due to the weight of the coin, which overcomes the weight B carried upon the arm I3 attached to the frame and acting normally to retain the side of the frame in which the slot is formed in its uppermost position and depresses that side. In this swinging movement of the frame the arm B also projecting from the frame, encounters a pin B projecting laterally from the gravitating dog B pivoted stationarily at B and resting normally on the periphery of a cam or sin gle-tooth ratchet-wheel B rigid on a shaft B projecting through the case, and provided on the outside of the latter with a crank B intended to be operated by the patron after he has inserted the coin. The rotation of this shaft in one direction is prevented, except when the dog is raised, by the en gagement of the dog with said wheel and is constantly prevented from turning in the other direction by the toothed wheel I3 and dog B said wheel meshing with a pinion B on shaft B Vith this construction, the slide 13 always acting to shorten the slot 13 only slightly within the diameter of the coin for which the chute is adjusted, it will be seen that if any one attempts fraud by putting in a coin of a smaller size than that for which he calls when he adjusts the lever B it will be without avail, because such coin instead of being arrested at the slot B will fall entirely through the slot, and thus fail to operate the frame B Thus no signal to the central office can be sent, as will be understood later on. The swinging of the coinarresting frame also accomplishes the release of the coin from the slot in the frame, as follows: The pinion B also meshes with a pinion 13 carrying a laterally-projecting pin B and when the said pinion is rotated the pin is moved against the lower end of a lever B made in right-angle form and pivoted upon a vertical pivot at B, the lever being thus turned slightly upon said pivot. The horizontal arm of the lever is slotted, as seen at Fig. 5, and this slot receives a pin 13, depending from a slide 13 at the opposite end of the slot from the slide 13, so that the slide I3 is moved in the direction necessary to release the coin upon the actuation of said lever by the pinion B The rotation given to shaft B by the patron through crank B also effects the sending of the proper signal to the central office, as follows: Upon the shaft B the same being the shaft of pinion B, are a series of contact-fingers B, a different number of fingers for each size coin, two fingers for nickels, three for quarters, four for half-dollars, and five for dollars. The shaft B is electrically connected to the buzzer by the spring B and the wire shown, and the fingers effect contact with a movable spring B depending from one end of a lever 13, pivoted at its opposite end B to the under surface of the top of case A and operated by a pin 13, depending from plate B and entering the slot B in the lever. The spring B is wired to the circuit-wire D, so that when the fingers B are brought against it the circuit is completed. As the patron moves the crank B through a complete revolution it will be seen that each finger in the series before which the spring is at the time stationed will strike the spring and send a separate signal to the central station, so that by counting the signals the operator at central will understand the size of the coin deposited.

By connecting the contact-spring to the plate which is actuated with slide B when the patron sets the lever B in the manner described the spring is with certainty positioned opposite the fingers which should give the signal, and the lever B is adapted to multiply the movement of the slide, so that the several series of fingers can be spaced sufficiently apart to prevent accidental contact by any of them with the spring except the ones properly acting to send the signal for the coin at which the machine is set.

In order that the spring 13 may always be presented with its fiat face squarely at right angles to all the contact-fingers, I pivot it to its operating-lever and keep it in this relative position by means of a governing-rod 13 extending laterally from and attached to the spring and passing freely through a guide or eye B secured in the top of the case.

As further safeguards against the use of wires or pickers the chute B is perforated along its bottom, as seen at Fig. 8, and a depending plate B is attached to it to shut off access to the coin-arresting frame or other parts of the mechanism. The chute O is inclined laterally, as at Fig. 3, and its under side is perforated, as shown, for the same purpose.
