LOUIS M. NELSON, OF DOUGLAS, WYOMING.

CHECK-OPERATED CONTROLLING MECHANISM.

Specification of Letters Patent.

Application filed January 18, 1909. Serial No. 472,945.

To all whom it may concern:

Be it known that I, LOUIS M. NELsoN, citizen of the United States, residing at Douglas, in the county of Converse and State of WVyoming, have invented certain new and useful Improvements in Check-Operated Controlling Mechanisms, of which the following is a specification.

This invention relates broadly to check cont-rolled apparatus and particularly to automatic motor actuated mechanism arranged to be set in motion by the introduction of the proper check, such as a coin or other token.

My invention has for its primary object a novel check operated controlling apparatus for mechanism such as that above mentioned, which is so arranged as to operate the automatic motor actuated mechanism in different ways, or more specifically for a different number of times, according to the denomination or predetermined character of the coin or other token deposited in the coinway of the check operated controlling apparatus.

Another and more specific object of my invention is an improved time selecting check operated controlling apparatus for an automatic phonograph, such as that disclosed by my application for Letters Patent of the United States, Serial No. 471,688, filed the 11th day of January 1909, so arranged that the phonograph will operate any desired number of times according to the character or denomination of the token used in starting the apparatus, and will automatically stop at the conclusion of the rendering of the number of selections represented by that token.

With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is a side elevation of my improved check operated controlling apparatus. Fig. 2 is a perspective view illustrating a portion of the mechanism that is designed to be controlled by said apparatus. Fig. 3 is a side elevation of the apparatus on an enlarged scale. Fig. 4 is a top plan view thereof, as well as a horizontal sectional view through the upper ends of the actuating levers. Fig. 5 is a rear elevation, and Fig. 6 is a detail perspective view of a swinging frame hereinafter specifically described.

Corresponding and like parts are referred to in the following description and are indicated in all the views of the drawings, by the same reference characters.

Referring to the drawings (Fig. 2), A designates a cam wheel which represents a movable element of motor actuated mechanism selected for the purpose of illustration only; B designates the drive wheel of a motor, which term is to be understood as including any prime mover or other driving part; and C, a governing mechanism which I have selected as an example to show some means for directly controlling the starting and stopping of the motor under the influence of my improved check operated apparatus which forms the basis of this invention. In the present instance, the governing mechanism includes a friction disk at and a friction brake Z) arranged to engage the disk and pivotally mounted intermediate of its ends on an suitable support, the upper arm of said frlction brake being designed for engagement by the depending crank 0 of a governor shaft cl, when said shaft is turned in one direction by the depressing of an arm 6 secured to said shaft and extending perpendicularly therefrom. The crank c operates in opposition to a spring 7, said spring being designed to move the governor shaft in a direction to release the disk at and permit the motor to act. To stop the motor, the governor arm 0 is depressed by a trigger 9, said trigger being pivotally mounted upon and carried by a lever h fulcrumed at one end on a support h. The lever 72, carries a roller 2' arranged to ride on the periphery of the cam wheel A to hold the lever in normal position and to drop into a depression 7c in the periphery of the cam wheel, so as to rock the lever in a direction to press its trigger g downwardly against the governor 6, thereby stopping the motor. It will be understood that while this automatic motor actuated mechanism forms a part of my automatic phonograph application, before mentioned, it is to be broadly considered as any mechanism of an analogous character, as my present invention broadly comprehends a check operated controlling appa- Patented Aug. 16, 1910.

this mechanism, it is only necessary to trip the trigger so as to release it from the governor arm, whereupon the spring 7' will release the friction brake Z) fromthe disk on and the motor will be permitted to act, turning the cam wheel A until the depression again reaches the roller 2', whereupon the lever will be permitted to drop and as it is dropped or lowered, the spring pressed trigger 9 will again bear down upon the governor arm 6, and'stop the motor until the trigger is again tripped by an element of my improved check operated controlling apparatus, which I shall now specifically describe.

Referring particularly to Fig. 1, D designates a coin-way or chute for coins of different denominations or checks or other tokens, the specific construction of said coinway being described and claimed in another co-pending application for Letters Patent of the United States, filed the 11th day of January, 1909, Serial No. 471,689. I have selected this coin-way in the present case for the purpose of illustration only. It is to be understood however, that the coin-way D separates or sorts the coins or tokens of different denominations as to size and also tests them, the present embodiment of the invention dealing with a coin-way for silver dollars, half-dollars, quarters, nickels and dimes. These are separated in the coin-way and if found to be of the proper weight and size and not mutilated are passed from the coin-way to a particular one of a series of trays, designated 10, 5, 25, 50 and 100, respectively, and designated for the coins of different denominations as aforesaid. These trays are respectively provided with upturned side edges 1 and retaining lips 2 (see Fig. 3) and the trays are respectively mounted on the upper ends of levers designated 10, 5 25, 50 and 100 respectively, as best seen in Fig. 5. These levers have a common axis intermediate of their ends being all mounted upon a rod 3, which extends transversely across the casing of the controlling apparatus, and which in the present instance is composed of side plates 4, 4 of any desired construction and design, except as hereinafter noted. The levers are so polsed that their upper ends will be held in proper juxtaposition to the discharge end of the coinway, until swung rearwardly and downwardly by the weight of the coin deposited in a tray, it being understood that the levers are independently movable and that they return to their'normal position as soon as the coins fall from the tray, through the tilting of the levers to a definite point, the coins dropping into a suitable receptacle (not shown). These levers are respectively provided with actuating rods 6, 7 8, 9, and 11 connected thereto at different distances from the common axis3 and all passing upwardly and forwardly through the upper cross-bar of a rectangular frame 12 mounted to swing freely on a transversely extending shaft 13.

'The upper extremities of these actuating rods (the rods being preferably constructed of wire), are bent to form hook aortions 15 which engage the upper edge 0 the upper cross-barof said frame, this construction providing that any one of the levers may be swung in an operative direction, and, through the instrumentality of the actuating rod, swing the frame 12 in an operative direction without actuating or drawing upon the other wires or actuating the other levers, the frame 12 being swung back to a substantially upright position by means of a weight 14 secured to its lower end.

A pawl 16 is pivotally mounted upon one side of the swinging frame 12 and is normally held in a neutral position, such as that illustrated in Fig. 3, by a raised portion 17 of the side plate 4 of the casing. This pawl is designed to engage the teeth of a ratchet wheel 18 which is secured to the shaft 13 and which is spring-pressed in an anti-clock-wise direction by means of a coiled-spring 19 secured to the side plate 4 and to the shaft. In the present instance the actuating rod 6 of the lever 5* is attached to said lever at a point nearer to the common axis 3 than any other actuating rod and it is so arranged that when the lever 5 is actuated it will cause the pawl 16 to 1'0- tate the ratchet wheel 18 a distance equal to one tooth. The actuating rod 7 of the lever 10 is correspondingly arranged to effect a clockwise movement ofthe ratchet wheel 18 a distance of two teeth, while the rods 8, 9, and 11, when pulled upon by their respective levers turn the ratchet wheel a distance equal to five teeth, ten teeth and twenty teeth, respectively. This arrangement is cited as an example for the reason that, as above stated, the invention is particularly designed for an automatic phonograph in which the deposit of a coin or token of a five cent value will cause one selection to be played, while for example the insertion of a token of a dollar value will result in the playing of twenty selections, one selection for each five cent value deposited. To provide for this selective operation, according to the different movements of the ratchet wheel 18 as turned under the influence of the different levers, said wheel is provided with a pin 20 which normally lies in engagement with one side of the u wardly projecting arm 21 of a bell-crank ever 22, said lever being fulcrumed at its elbow as at 23, while the lower arm 21 of said bell-crank is under the pulling tension of a compression spring 24 secured thereto and to the plate 4 of the casing, the said spring exerting a tension upon the bell-crank to swing the upper arm 21 inwardly or toward the center of the ratchet wheel. The lower arm 21 of the bell-crank 22 is connected to the lower end of a link in the form of a rod 26, said link extending upwardly and having its upper end operatively connected to the trigger of the lever h in such a manner that a downward pull upon said link will trip the trigger g from the governor arm 6 while the subsequent upwardly swinging movement of the lever will impart an upward movement to the link, overcoming the tension of the spring 24.

From the foregoing description, it will be seen that as one of the coin actuated levers turns the ratchet wheel 18 in a clock-wise direction, the pin 20 of the ratchet wheel will pass away from and out of contact with the arm 21 of the bell-crank 22 and this will permit the spring 24 to rock said bellcrank in a direction to pull upon the link 26 and trip the trigger 9, thereby automatically starting the motor actuated mechanism, and, specifically, resulting in the rotation of the cam wheel A. As the cam wheel rotates, the roller '5 of the lever it will pass out of the depression 76, thereby swinging the lever upwardly and effecting an upward pull upon the link 26, thereby rocking the bellcrank 22 against the tension of the spring 24: and the upper arm 21 of the bell-crank outwardly or away from the center of the ratchet wheel 18. The said arm 21 is provided with an outwardly projecting finger 27, and as said arm is thus swung outwardly, it will actuate a counter 29 of any desired type or construction, through the instrumentality of a connecting rod 28 secured to the finger 27 and to the operative portion of the counter 29, thereby indicating the number of selections played, and serving as a register. Furthermore the outward movement of the arm 21 causes its finger 27 to engage an escapement pawl 30 pivoted intermediate of its ends as at 31 and acted upon by a spring 32 to press its upper end into engagement with the teeth of the ratchet wheel 18. The escapement pawl 30 will thus be disengaged from the ratchet wheel, but at the same time the co-acting escapement pawl 33 will be permitted to engage another tooth of the wheel, and the wheel will be permitted to turn backwardly one step. The movement of the escapement pawl 33 in a direction to engage the ratchet wheel is permitted by pivoting said pawl 33 intermediate of its ends as at 34: and connecting a compression spring 35 to its lower end, such lower end being formed with a lug 36 designed to be engaged by the inner edge of the arm 21, and as said arm moves outwardly, as before stated, it will move away from the lug and permit the spring 35 to act to swing the upper engaging end of the pawl 33 inwardly. It is to be understood that these movements, just described, are effected by an upward pull upon the link 26,

caused by the upwardly swinging movement of the lever h and the subsequent riding of the roller '5 upon the regular or undepressed portion of the periphery of the cam wheel A. As soon, however, as the cam wheel has completed a revolution and brought its depression 7c again into alinement with the roller 6 the lever it will drop permitting the spring 24 to again pull upon the link 26 so as to draw the trigger out of operative relation to the governor arm 6, while at the same time, the spring 24 will rock the bellcrank in a direction to swing its upper arm 21 inwardly. This inward movement of the said arm will manifestly release the escapement pawl 30 and permit its spring to draw it into engagement with another tooth of the ratchet wheel, while at the same time the rear edge of the arm 21 will engage the lug 36 and rock the escapement pawl 33 in a direction to disengage its upper end from the tooth that it has been engaging, thereby permitting the ratchet wheel to move backwardly another tooth. This operation is repeated until the ratchet wheel 18 has thus moved step by step in a rearward direction far enough to bring its pin 20 against the inner edge of the arm 21 of the bell-crank 22, whereupon the spring 24 will not be again permitted to act to draw downwardly upon the link 26 until another coin or other similar token has been deposited in the machine, the machine being thereby brought to a stand still with the lever in in lowered position with the roller i and with the trigger g pressing downwardly upon the governor arm 6 to hold the motor B inoperative.

If desired, the shaft 13 may carry at one end an indicator disk 37 containing either on its periphery or outer face, or both, a series of numbers indicating the number of pieces that will be played after the in troduction of any coin or other token, the said indicator disk being movable with the ratchet wheel 18 and so arranged that when the ratchet wheel is returned to its normal stop position, the indicator disk will not disclose any of its indicating numerals, For example, when with the embodiment of the invention herein described, a dollar is inserted in the coin chute, the ratchet wheel 18 will be turned twenty teeth, and the indicator disk will display the numeral 20 at any suitable side opening in the cabinet (not shown). As the selections are played one after another, and at the conclusion of each selection, the ratchet wheel will turn rearwardly as well as the indicator disk, so as to display the numeral 19 at the end of the first selection, the numeral 18 at the end of the second, and so on.
