Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed March 28, 1907. Serial No. 365,102.

To all whom it may concern:

Be it known that I, JOHN W. EILER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Slug-Detectors, of which the following is a description.

My invention relates to an attachment for coin controlled devices for retaining the coin last deposited in the device .for operating the same, where it may be readily inspected to detect the use of slugs or other means for avoiding the actual depositing of the coin required.

The object of my invention is to provide a simple, sure, and eflicient device of the kind described, and one not easily rendered inoperative when in service.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar reference characters indicate like or corresponding parts; Figure 1 is a side elevation of my device mounted in operative position. Fig. 2 is an edge elevation of the same. Fig. 3 is a section taken substantially on line 33 of Fig. 2. Fig. 4 is a section similar to that shown in Fig. 3, but with the parts moved to operate the device. Fig. 5 is a section taken substantially on line 5-5 of Fig. 3. Fig. 6 is a section taken substantially on line 66 of Fig. 3. Fig. 7 is an enlarged section taken substantially on line 7-7 of Fig. 3; and Fig. 8 is a section taken substantially on line 88 of Fig. 5.

In the preferred form of my device shown in the drawings, 1 is a coin receiver having an inlet 2 near one end, an outlet 3 near the opposite end, and a coin passage 4 extending longitudinally thereof and connecting said inlet and outlet and having a transparent panel 5 at one side extending substantially its entire length so that any coins or similar articles therein may be plainly seen and their exact character determined. The passage 4 may be of any desired length and formed to receive any particular coin or slug, the form shown being especially designed to operate in connection with a telephone coin box 11 of the usual or any preferred form and with the common five cent piece or nickel. The inlet, outlet and passage above described are preferably formed to adapt the device to the coin box to which it is attached and so arranged that the particular coin for operating the device when inserted in the inlet will pass preferably by gravity at once into the passage 4 toward the outlet and if not prevented would pass directly from the passage 4 into the outlet and escape from the device.

Any suitably formed movable obstruction may be provided in the passage 4 preferably near the outlet 3 to prevent the escape of coins from the passage 4 as above described. In the form shown a lever 6 is pivotally mounted upon the wall 10 of the passage 4 as at 7 and provided with a part 8 extending through an opening 9 in the wall for this purpose. A spring 12 or other suitable resillent means is suitably attached to the plate 10 and engages the free end of the lever 6 to normally hold the part 8 in position in the passage 4.

Suitable means are also preferably provided to control the operation of my device. As shown an operating handle 14 is pivotally mounted near the inlet 2 and provided with a part 15 adapted to cooperate with a stop 16 upon the receiver to limit the movement of the handle in one direction. A spring 17 or other suitable resilient means is preferably provided to normally retain the handle at the limit of its movement in this direction. The handle 14 is also provided with a part 18 adapted to enter the passage 4 at each operative movement of the handle, and when a suitable number of coins are positioned in the passage, to force the coins along the passage toward the outlet. The obstruction 8 is so positioned that this movement of the coin with which it is engaged, forces the obstruction out of the passage and a single coin passes into the outlet, the obstruction immediately returning to its position in the passage to engage the next succeeding coin. The handle 14 is also provided with an arm 19 arranged to normally engage a projection 20 upon the lever 6 and lock the lever in position. WVhen however the handle 14 is operatively moved the arm 19 is disengaged from the projection 20 thus releasing the lever 6 so that the part 18 upon the handle may cooperate with the coins in the passage to move the obstruction as .before described. The projection 20 and arm 19 are preferably so formed that when the lever 6 is moved as above described the part 20 is moved into the path of the arm 19 in a position tomoperate therewith to prevent retraction of the handle 14 until the obstruction S is returned to its position in the passage, the parts thus cooperating to prevent the simultaneous opening of both the inlet and outlet of the passage 4.

In the preferred construction an alarm is provided, arranged to operate each time a suitable coin passes the obstruction 8 into the outlet. As shown a gong 21 is mounted in any desired manner upon the plate 10, and a striker 22 or equivalent means for sounding the gong is attached to the lever 6 by a spring wire 23.

Any preferred means may be provided to operate the striker each time the obstruction 8 is removed from its position in the passage. In the preferred construction shown the wire 23 is offset as at 24 and a pin 25 or equivalent means is provided upon the arm 19 so positioned that when the handle 14 is operated without a sufficient number of coins in the passage to move the lever 6 the pin 25 will pass the wire 23 without engaging the same but when the handle let and lever 6 are moved simultaneously the offset portion of the wire is engaged by the pin and the striker is retracted and suddenly released as the lever 6, at the escape of a coin, resumes its normal position, striking the gong a sharp blow as the striker returns to its normal position.

If desired a second alarm may be provided arranged to be situated ata point at a considerable distance from my device. This alarm may consist of an electric bell 26 of the usual or any preferred form as shown in Fig. 8, arranged to be operated by a battery 27 each time the lever 6 is operated. As shown the battery 27 is connected by means of a conductor 28 to one pole of the bell and by a similar conductor 29 to a shield or cover 30 rigidly attached to the receiver 1 in position to prevent interference with the gong or other mechanism of my device. A conductor 31 is arranged to connect the other pole of the bell 26 with a suitable spring contact 32 upon the shield 30 normally insulated therefrom but adapted to be operated to close the current by a part of the lever 6 so that each time the lever is moved out of its normal position the circuit will be closed thus operating the alarm.

If desired a portion upon the member 14 may be extended as at 33 and arranged to engage a stop 34 positioned opposite the stop 16 when the handle is in its normal position so that there will be substantially no strain upon the pivotal connection of the handle in case it is pushed back against the stops and little or no danger of injury to the device.

In operation enough coins are positioned in the passage 4 so that when another coin is introduced it will be in position to be engaged by the part 18 when the handle 14 is operated and cooperate with the other coins in the device to force the coin nearest the outlet, past the obstruction 8 as herein described and into the outlet where it is free to escape into the coin box 11. Obviously therefore a coin is discharged from the device each time one is introduced thus leaving the last coin inserted in the device in full view through the transparent panel 5, in the preferred construction the panel 5 being of sufficient length to' expose several coins so that if a party should deposit several coins in the device they may all be examined before passing into the coin box 11.

Having thus described my improvement, it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form. and construetion shown.
