A conrona'rron F 1LLmo1s COIN CONTROLLED SWITCH AND TIMING MECHAfiifiM Applcation filed September 21, 1929. Serial No. 394,162.

This invention relates to improvements in switch operating and control mechanism, and one of the objects ofthe same is to provide improved mechanism whereby upon the insertion of a predetermined coin or other suitable token, a control switch will be actuated and motor mechanism, preferably though not necessarily clock mechanism, will be set into motion and the parts of the switch actuating mechanism will be set so that after a predetermined period of time of operation of the motor mechanism the switch will be automatically actuated.

A further object is to provide improved mechanism of this character embodying a switch operating element havin a predetermined extent of movement and means also adapted to be set whereby the time of opera tion of the switch in the period of movement of vthe said element may be varied.

A further object is to provide in a mecha- 'nism of this character a-motor having an escapement mechanism and improved means whereby uponthe actuation of the switch device motion will be imparted directly to the escapement mechanism to start the motor.

To the attainment of these ends and the accomplishmentof other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this 111- will assume to set the switch operating element in a position to close the switch.

Figure 5 is a view similar to Figure 4 at the completion of the operation which was begun in Figure 4, and showingthe parts in the position which they will assume just before the motor is started in its operation.

Referring more particularly to the drawings the numeral designates a supporting plate upon which is mounted an operating handle 11 that operates a check carrier, after the check or coin has been inserted thereinto.

The check controlled mechanism is preferably of the construction shown in my prior Patent Number 1,452,721, issued April 24,

1923, but may be of any desired or suitable construction. Sufiice it to say, that when a proper check is inserted in the check slot and the handle 11 is actuated against the stress of the spring 12, the check will be carried forward and at apredetermined time in the cycle of operation thereof will be deposited into the machine.

By the insertion of the check or coin the handle 11, through the intermediate mechanism, is operatively connected with a rotatable disc 13, suitably mounted.

All of the above referred to parts, however, are of the ordinary and well known construction and constitute no part of the present invention.

Supported in any suitable manner from the plate 10 and in the rear thereof is another supporting plate 14, and secured to this plate 14 and supported thereby is a suitable bracket 15, and which bracket supports and holds a motor device designated generally by the reference numeral 16 spaced from the plate or member 14.

The motor 16 may be of'any desired construction, but is here shown as being constitluted of the spring type having a balance wheel 17 which controls an escapement lever 18, the arms 19 of the lever co-operating with the escapement ratchet 20. Carried by'the shaft of the escapement ratchet 20 is a gear 21 and meshing with this gear 21 is a 22, and a train of gears 23 is disposed between gear Carried by the element 26 is a spring controlled dog 30 which engages the teeth of the gear wheel 24. A spring 31 is anchored by one end to a fixed support as at 32 and is connected by its other end 33 with the element 26. The purpose of the spring 31 is to swing the member 26 about its pivotal support and by reason of the engagement of the pawl or dog 30 with the teeth of the gear 24 rotate the latter, and as the element 26 is pivotally mounted, it will be manifest that it will move to the right in Figure 1, until the I lip or projection 27 thereon engages the screw 28. Therefore, by adjusting the screw 28, it will be manifest that the extent of movement of the element 26 under the stress 0 the sprin 31 may be varied.

The switch device 34 to be operated is preferably of the snap type and is provided with an operating handle or button 35.

Carried with the element 26 is a member 36 which is provided with a deflected portion 37, in the path of movement of which portion 37 the handle or button 35 of the switch is arranged so that assuming the handle or button 35 of the switch 34 and the element 26 andmember 36 to be in the position shown in Figure 5, the spring 31 will be under tension and will exert its stress upon the element 26 tending to move it to the right in Figure 5.

This movement, however, is arrested by reason of the fact that the pawl or dog 30 engages in the teeth of the gear 24. The rotation of the gear 24 is retarded through the train of gears 2322 and the movement of these gears in turn is controlled by the actuation of the escapement mechanism 1819-20, as well as the balance wheel 17.

Therefore, assuming the parts to be in the position shown in Figure 5, and the escapement mechanism operating, it will be manifest that the gear 24 will be rotated and as this gear is rotated in the direction shown by the arrow in Figure 5, the deflected portion 37 of the member 36 will be gradually moved to the right until the portion 37 of the member 36 engages and shifts the handle or button 35 of the switch device 34. This will impart an initial movement to the handle or button 35 and the switch will snap over to interrupt the circuit. At this time the shoulder or projection 27 (see Figure 1) on the element226 will engage the screw or stop device Pivotally mounted upon a suitable support, preferably the plate 14, as at 39 and intermediate its ends, is a lever 40. One end of this lever is bifurcated or cut away as at 41 and into this cut away portion or bifurcation the handle or button 35 projects so that by swinging the lever 40 about its pivot in either direction, the switch handle or button 35 will be operated by the engagement of the respective walls of the bifurcation 41.

The lever 40 is operated by means of the disc 13 through the medium of a rojection 42 carried by the disc. This pro ection 42 engages one of the faces of the tapered extremity 43 of a member 44 that is pivotally supported intermediate its ends as at 45 upon a suitable support, preferably the plate 14, to rock the member 44 about its pivot in one direction, when the disc 13 is moving in the direction indicated by the arrows in Figure 4. When, however, the disc 13 is rotated in the opposite direction or in the direction of the arrowas shown in Figure 5, then the projection 42 will engage the other tapered or beveled extremity 43 of the member 44 to rock the latter in the o posite direction. A spring 46 is connected by one end as at 47 to the member 44 and is anchored by its other end as at 48 to a fixed support, preferably the plate 14.

The lever 40 is swung about its pivot 39 by the operation of the member 44 and this is accomplished through the medium of a link 49 which is pivotally connected as at 50 with the member 44 at one end and at its other end is pivotally connected as at 51 with the lever 40. Thus it will be seen that by swinging the member 44 about its pivot in either direction the lever 40 will be correspondingly moved and the spring 46 will operate to hold the member 44 in its adjusted position.

The lever 44 as well as the member 40 are preferably located in close proximity to the supporting plate 14 and in positions that during their operation or movements about their pivots they will not interfere with the operation of another member or lever 52, the latter being pivotally supported intermediate its ends, preferably upon the shaft 25. The upper end of the lever 52 is arranged within the path of movement of a roller 53 forming an extension of the projection 42 and the lower end 54 of the lever 52 is connected to the member 36, through the medium of a fastening device 55 which passes through the Igember 36 and engages the end of the lever The member 36 is provided with a plurallty of openings 56 into which the fastening device 55 may be placed to connect the lever 52 with the member 36, to vary the time of the engagement of the deflected portion 37 of the member 36 with the handle or button 35 of the switch. Through the medium of the connection of the lever 52 with the memcuit.

ber 36 by the fastening device .55, it will be manifest that when the. disc '13 is rotated and the roller 53 engages the adjacent end of the lever 52 to swing it about its pivot to the right in Figure 3, the yoke or member 26 will be moved aboutits pivot to the left in Figure 3, and against the stress of the spring 31, during the movement oi the disc 13 in one direction or in the direction indicated by the arrow in Figure 3. This will set the motor so that when the disc 13 is rotated in the opposite direction to move the roller 53 away from the lever 52, the stress of the spring 31 will tend to pull the

members

36 and 26 forwardly, or to the right in Figure 3 to rotate the gear 24 and thereby operate the motor. The motor, however, is not self-starting and therefore in order to start the motor it is necessary to shift or move the escapement lever 18. This may be accomplished in the following manner.

Carried by the end of the lever 40, preferably by being secured thereto by a fastening device as at 57, is an arm 58 preferably in the form of a spring wire. This arm is disposed adjacent the escapement lever 18 and is so shaped that when the lever 40 is moved in a direction that the upper end thereof will assume the position shown in Figure 5, the end of the arm 58 will engage behind the escapement lever 18 and move it in one direction. When, however, the lever 40 is moved in the opposite direction or into'the position shown in Figure 3, the end of the arm 58 willmove away from the escapement lever 18, thereby allowing the latter, under the influence of the balance wheel 17, to move in the opposite direction and thereby. start the motor.

The arm 58 being of resilient or spring material, will prevent injury. to the parts, yet will be sufiiciently strong to move the escapement lever 18. When the lever 40 is moved into the position shown in Figure 5, the handle or button 35 of the switch will be moved into a position to complete the circuit through the conductors 38 and the member 26 will also be moved against the stress of the spring 31.

The motor will continue to operate under the influence of the spring 31 until the deflected portion 37 of the member 36 engages and moves the switch handle or button 35 from the position shown in Figure 5 to the position shown in Figure 3, at which time the switch button or handle will snap over and close the circuit. The motor will be stopped or arrested in its movement by the engagement of the projection 27 on the element 26 engaging the stop screw 28. This will occur just at the time that the switch handle or button 35 snaps over to interrupt the cir- Therefore, by adjusting the point of connection of the lower end 54 of the lever 52 with the member 36, through the medium of the fastening device 55 and the holes 56 in the member 36, the time in the cycle of operation of the mechanism at which the deflected portion 37 of the member 36 will engage the switch handle or button 35, may be varied,

and likewise the time at which the movement of the element 26 will be arrested may be 59 is deposited into the mechanism so that the disc 13 can be rotated in the direction indicated by the arrow, the anti-friction roller 53 will engage one of the beveled faces of the end of the member 44 and the latter will yield to permit the roller to pass thereover.

Upon a continued movement of the disc 13 in the same direction the projection 42 will then engage the end of the lever 52 to rock the latter about its pivot 27 and the

members

26 and 36 from the position shown in Figure 3, to the position shown in Figure 4. When the member 26 has reached the limit of its movement in this direction the dog or pawl 30 will engage between the teeth of the gear wheel 24 and the spring 31 will be placed under tension so that when the lever 52 is released by the projection 42 moving out of engagement therewith the spring 31 will operate to rotate the gear 24 and consequently the motor.

The parts are shown at their extreme points of movement in this direction in Figure 4. The handle 11 of the check controlled mechanism is then released so that the disc 13 can return in the opposite direction under the stress of the spring '12. that is, moved the arrows in Figure 5, the anti-friction roller 42 will engage the beveled face of the member 44 and move it from the position shown in Figures 3 and 4 to the position shown in Figure 5, and then the member 44 will yield to permit the anti-friction roller to pass thereover. During this movement of the member 44 the link 49 will move the lever 40 from the position-shown in Figure 4, to the position shown in Figure 5, to actuate the switch handle or button 35 to render the circuit inactive, if the circuit should happen to be active at that time. "A continued movement, however, of the disc 13 in the same direction will cause the anti-friction roller 53 to pass over the end of the member 44, the latter yielding to permit such movement. Just at the time that the anti-friction roller thus disengages the end of the member 44, the spring 46 will quickly return the member 44 to the position shown in Figure 4.

i the lever 40 so as to swing the. escapoment lever about its pivot in one direction and then release the same, thereby starting the balance wheel 17 to operate the escapement mechanism 18-20.

The motor will then continue to run until the deflected portion 37 of theanember 36 engages the switch handle or button 35 to move the latter from the position shown in Figure 5 back to the position shown in Figures 3 and 4, to interrupt thercircuit. Just at this time the projection 27 on the member 26 will engage the stop device 28 and the motor will also be stopped.
