COIN-CONTROL FOR MOTOR-VEHICLES.

useful Improvement in; Goin-Control for Motor-Vehicles, of which the following is a specification. I 1

Our invention relates to improvements in devices of the type illustrated in United States Letters Patent No. 964,845, dated July 19, 1910, and its object is to improve the same in certain particulars hereinafter more fully set forth.

In the drawings, Figure 1 represents a front elevation of a complete device embodying our invention and Fig. 2 a similar view of the device with the front cover and certain of the working parts removed. Fig. 3 is a detail View of the device for winding Fig. 4 is a view in transverse vertical section of the device of Fig. 1. Figs. 5 and 6 are detail views of portions of the mechanism which will be hereinafter more fully referred to. Fig. 7 is a diagram of the electric circuits and apparatus.

In the Letters Patent above referred to, the broad idea was set forth of a time-controlled coin-operating mechanism for regulating the use of a vehicle. According to our present invention we have provided such amechanism wherein upon the insertion of a coin and the operation of a push-rod (1) the coin is deposited in the locked receiving chamber of the machine, (2) an indicator is moved forward over a dial to indicate the length of time of occupation of the vehicle for which prepayment has been made, and (3) the electric. operating-circuit of the vehicle is made operative.

A represents the casing of the machine and B the time-indicating dial, C represents the indicator and D (see Fig. 4:) the push rod by means of which the coin-slide E is moved into the machine after the coin has been deposited. This coin-slide is of the character shown in Letters Patent No. 625,123, dated May 16, 1899. When the slide is pushed in, its inner end first strikes against one arm F of a bell-crank-lever (see Fig. 5) the other arm G of which is connected to a slide H carrying a spring-pressed pawl I. This pawl I engages with a ratchet tooth attached to the indicator C and when the bell-crank-lever is rocked by pressing in the push-rod, the indicator C is given a quarter turn over the dial, thereby indicating the time of occupation of the vehicle for which payment has been made.

The inner end of the coin-carrying slide E is provided with a latch J, and when the slide is pushed in to its greatest extent, this latch engages with one arm K of a lever; the push-rod being then released, the spring L forces it back to its normal position and on its passage back, the latch J draws the lever K until its opposite arm M is forced into engagement with a circuit-closing device N. When in this position, the arm K of the lever (see Fig. 6) has passed a camlock upon an armature O, by which look the lever K is held from returning and breaking the contact at M N under the tension of the spring P. The hand Q, which, by reason of the advancement of the indicator C a quarter turn, had been left a quarter turn behind, proceeds under the operation of a motor which may be a spring-actuated motor, such as the clock mechanism as shown to pass through this quarter turn until it contacts with a terminal R mounted upon said indicator C (see Figs. 1 and 7). When the hand Q herein shown as a circuit-closing hand-is in contact with the terminal R a circuit is completed through a battery and bell as shown at the left ofFig. 7, and the bell is rung warning the passenger that the time of occupation prepaid is about to expire. If the passenger desires to extend such time, he may by inserting another coin once more move the indicator forward another quarter turn. the contact being still closed at M N. If he does not desire so to do, the hand Q continues to travel until it reaches the second terminal R upon the indicator C. This closes a circuit comprising a battery and a magnet S, Fig. 6) and this magnet drawing to itself its armature 0, releases the end K of the lever K M, and the spring P withdraws the end M of said lever out of contact at M N, thus breaking the operating circuit in the vehicle. As the clock mechanism will normally continue to operate, the hand Q shortly after passing over the contact R will bear against the stop R on the indicator C and be thereby prevented from further motion, this result being permitted by the employment of a familiar friction device T. (See Fig. 4:.)

In order to Wind the clock-mechanism conveniently, a Winding arm U is provided carrying a spring-pawl V which engages with a winding ratchet as shown. In order to keep this pawl clear of the path of the teeth of said ratchet when the latter is moved in a counter-winding direction, apiece 42 mounted on the pawl is arranged to bear against a cam-surface W (see Fig.- 3) when the winding arm U is brought back to its normal position.

WVe claim:

In a device of the 'character described, as manually-operated member, a rotatably-v mounted indicator, means operable by said member for rotating said indicator a predetermined amount, a plurality of circuitterminals carried by said indicator and amotor-rotated circuit-closing hand mounted for rotation about thesame center as said indicator and turning independently thereof, said circuit-closing; hand being arranged to contact successively with said circuitclosing terminals in the course of its rotation.

In testimony whereof, we have hereunto subscribed our names this 13th day of December, 1910.
