COIN-OPERATING MEGMNESM.

To all whom "it may concern:

Be it known that We,=.l lnnus'r F. SYMONDS and 'Gnonen XV. BRAKE, citizens of the United States, and residents of Salem, Massachusetts, Essex county, have invented cerin new and useful Improvements in Coin Operating Mechanism, of which the followin is a specification.

The invention relates to coin operating mechanism and its object is to provide a simple and reliable mechanisl'n by which an electric circuit may be closed upon the in troduction of a coin and thereafter autol to automatically open the :circuit after a predetermined. time.

Certain features of the invention relating to the circuit closing devices may be embodielin any construction wherein it is de- 1 aimed to control, an electric circuit by the intion of the mechanism ern troduction of a coin.

iIu theeeeon panylng drawings the features of the IILVEIIUOII are shown embodied in a machine in which an electric motor is the timing earn; an view on'hne 5-5 Fig. l.

sterted' into-.0 oration by the introduction of thecoin an in which the OlICllltylS enton'iatieallyopened to stop the motor by a timin mechanism driven from the motor.

operation upon the introduction of a coin are operated and driven by an electric motor 2 winchdspruvided with binding posts 3, ,4, to which wiresleading "from the sourceof electrical sup I)! may be connected. One

terminal 5 o [the ,motor is connected by means of a wire o with the binding psi; 3 and the other terminal 7 is connected by a wire 8 with the devices by which the motor circuit is completed and broken in starting andstopping the motor. These devices consist of contact plates l2mounted upon an insulating block 13 and connected with the wire- 8 by means of a binding post 14, Cooperating with the contact 12 is a contact lever lh pivoted at 16 to an insulating block 17 and connected with the binding post 4 by means of awire 11.

Under. normal conditions the contact lever 15 1s heldout. of engagement with contacts 12 by means of a latch arm '18 which engages the lower end of the lever and holds, it 111 position against the tension of the spring 19. The latch .arm 18 is carried by a plate 20 which is pivoted at 21 and is provided at its forward end with a ledge 22arranged below a coin chute 23. Directly in the rear of the ledge 22 is an opening 24 in the plate 20 which overlies a chute 25. The plate 20 is provided with guard flanges 26, 2G for .in-

suring the engagement of the coin with the ledge 22as'the coin falls out of the lowerend of the coin chute 23. The guard flange 26 is inclined toward the opening 24 and acts to deflectthe coin through the opening 2; im-

mediately after the coin has .struck the eo ledge 22.

The plate20 with its connected latch arni 18 is held in normal position: against the lower end of, a stop plate 10 by nieansof l spring 27. The upper end of the spring 27 20. The stop: plate 10 isalso adjuetably mounted upon the supporting bracket 9'by means of screws 19 passing ,throughmhe vertical-slot lOin the plate. Byadp tins this plate 'the distance through wh ch-the latch arm '18 must travel in releasing eontact leve1-,l5 may be variedin adjusting the devices tooperete with coins of d fferent When a coin is introduced into the coin upon the ledge 22, the blow of the coin cansing the latch plate 20 to swing downward against the tension of its spring so that. the 2 contact lever 15 is released. When the contact lever is thus released it swings toward the left. in Fig. 2 under the action of its spring mg a pressed position. The coin is immediately deflected oil' of the ledge 22 by means ot' the ard plate 26 and falls through the openmg 24 into the chute 2:; by which it is directed into a coin receptacle '28.

When the contact lever 15 swings toward the left it passes between the contact plat cs 12 thus completing the electric circuit for the motor and starting the motor. The motor will now continue in action until the contact lever 15 is swung toward the right in Fig. 2 to disengage it from contacts 12 when the motor will come to rest.

The motor is connected by means of a belt 29 with a shaft. 30 so that the shaft. 30 is driven from the motor. This shaft may be connected with the mechanism or devices which it is desired to throw into operation upon the introduction of a coin and which are to remain in operation a definite period of time. The contact lever 15 is operated to diseiiga o it from the contacts 12 aml thus arrest t e o eration of the motor and the mechanism riven thereby after they have been in operation a prcdet-i'mined time through the action of a timin mechanism operated from the shaft 30. lhis timing mechanism in the form shown comprises a worm 31 secured to the shaft 30 and engag: ing a worm wheel 32 which is secured to a vertical shaft. A timing cam 33 is secured to this shaft and is arranged to act upon a roll 34 carried by a yoke or frame 35 which is suspended upon the shaft 30. The roll 34 on the yoke is held in engagement with the timing cam 33 by the weight of the yoke or the parts carried thereby or may be thus held by the action of a spring.

arm of the yoke 35 extends above shaft 30 and is provided with a rearwardly projecting plate 36. Pivoted to this plate is a. latch arm 37 provided near its outer end with a notch or shoulder 38. The latch arm 37 is supported upon a pin 39 and is guided over the pin between the gear surface of the coin chute 23 and a. guide strap 40 is secured to the rear side of the coin chute.

When the parts are in normal position with the motor out of actiomthe roll 34 ridesupon the low part of the cam 33 and the latch arm 37 is supported upon the pin 39 in the position indicated in Fig. 2. When the motor is started by the introduction of a. coin the cam 33 is rotated andthe roll 34 19, the lower end of the lever pass- I we the latch arm 18 so that the plate 20 and latch arm 18 are held in their do i One rides on to the high part of the cam thus swinging the upper end of the yoke toward the right in Fig. 2 and carryin the recess 1 258 in the latch arm 37 to the rig it of a pin it which projects from the upper end of the l contact lever 15. As the latch arm 37 is i moved into this position the pin 39 enters i a recess -12 in the lower edge of the arm so that the recess 38 will engage the in4l when l the arm ii moves toward the le t.. During the time that the roll ZH is riding on the i high pa rt ot' the cam the yoke 35 will remain in lixed position and the motor and parts driven thereby will remain in o oration.

When the cam has nearly complete a revolution the roller 3%. will ride down the int'linc 42% on the cam so that the upper end of toward the left. During this movement the shoulder or recess 38 acting on the pin 41 will swing the lower end of the contact lever 15 toward the right disengaging it from the contacts 12. This movement of the contact lcver will carry its lower end from above the latch arm 18 so that the coin plate 20 and latch arm 18 may swing up into the position indicated in Fig. 2 where the latch arm will act to hold the contact lever out of engagement w th the contacts 12. When the motor circuit is thus broken the momentum o. the parts will complete the revolution of the timing cam 33 so that the parts will be re turned to the position indicated in the drawings. During this movement the inclined surface of the recess 42 in the arm 37 rides over the pin 35) lifting the notch 38 out of engagement. with the pin 41.
