Application filed October 17, 1910. Serial No. 587,436.

To all whom it may concern:

Be it known that we, CLARENCE C. TRAVIS, BETHUEL M. DAVIS, and ALFRED D. ANTOINE, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Check-Controlled Mechanism, of which the following is a specification.v

This invention relates to improvements in check controlled mechanism for vending machines,A embodying a receptacle for delivering the commodity and one of the objects of the present invention is to provide improved means whereby when the receptacle is released by the check it will be advanced at a greater rate of speed than the speed of advancement of the check conveying means and in the same direction therewith, and improved means whereby the check conveying means may be advanced beyond the limit of movement of the delivery receptacle to release or discharge the check.

A further object is to provide an improved elastic connection between the check conveying means and the delivery receptacle u pon which tension is created by the operation of the check conveying means in the direction to release the receptacle, so that when the delivery receptacle is released by the check, the tension of the elastic connection will be exerted upon the delivery receptacle to cause the latter to spring forwardly.

A further object is to provide improved means for locking the receptacle against retrograde movement and improved means whereby the elastic connection will serve to return the check conveying means to operating position after the check has been discharged therefrom, and improved means for limiting such return movement.

A further object is to provide an improved device of this character which will be simple, durable and cheap in construction and eective and efficient in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the ac companying drawings illustrating an embodiment of the invention, and in which- Figure 1 is a detail side elevation of an improved device of this character constructed in accordance with the principles of this invention. Fig. 2 is an enlarged sectional view on line 2 2 of Fig. 1. Fig. 3 is a sectional view on line 3 3 of Fig. 7. Fig. 4 is a detail perspective view of the locking dog or retaining pawl for the delivery re ceptacle. Fig. 5 is a detail view partly in sect-ion with the front plate removed. Fig. 6 is a detail perspective view of the check or coin detector. Fig. 7 is a top plan view of Fig. 1. Fig. 8 is a detail sectional view showing the connection between the commodity delivering receptacle and the check conveying means.

Referring more particularly to the drawings, the numeral 10 designates a face plate which may be of any desired size and configuration, in which is journaled one extremity of the shaft 11 of an operating handle 12. Secured to the shaft 11 and adjacent the face of the plate 10 opposite to that adjacent which the operating handle 12 is located is a check or coin conveyer which is preferably-in the form of a disk 13 having a plurality of pockets or check receptacles 14:, and this disk 13 is located in close proximity to the face of the plate and is located between the plate 10 and a second plate 15. These plates 10 and 15 coperate with the check receptacles or pockets to hold the check in position to be advanced by the disk 13 when the handle 12 is rotated in a clock wise direction. Secured also to the shaft 11 and in close proximity to the rear face of the disk 13 is a disk or wheel 16 provided with spaced peripheral teeth 17. The plate 15 is preferably recessed or cutaway at its lower edge as at 1Sa so that a portion of the periphery of the disk 13 will extend into the cut away portion, as shown in Fig. 2, thereby permitting the inner face of the disk 13 to stand substantially flush with the inner face of the plate 15. The teeth 17 on the disk 16 are preferably of a length that their extremities will terminate adjacent the periphery of the disk 13 and these teeth or projections 17 coperate with a coin detector 18. The detector 18 is supported in any desired or suitable manner but preferably by one extremity thereof which is secured to a suitable support preferably the plate 13 by means of a suitable fastening device 19.

The free extremity of the detector projects over the disk 13 so as to extend into the space between two adjacent teeth 17 on the disk 1G and an elastic member 20, such as a leaf spring or the like, is provided which tends normally to hold the free extremity 21 of the detector in the space between two adjacent teeth 1T. This detector is provided adjacent its free end with a lateral projection 21, which is adapted to enter the pookets 1l in the check conveying disk 18 when no check is in the pocket or when a bogus check is inserted therein and which check is not of the proper thickness. The free extremity of the detector 18 is recessed as at 22 to form a shoulder 23 and the lateral pro jection 21 is beveled as shown so thatwhen the check 2d, of a proper denomination or value, is advanced by the check conveying disk 13 its edge will engage the inclined or beveled projection 21 on the detect-or 1S to more the latter so as to move the shoulder 23 out of the path of movement of the advancing projection 17 on the disk 16, and against the tension of the elastic member 20 so as to permit the tooth or projection 1T to pass the projection 21. lifter this tooth or projection 17 has passed the projection 21 the elastic member will force the detector 18 back to its orginal position to cause the projection 21 thereon to enter the next coin pocket or receptacle 141 and also to move the shoulder` 23 on the detector into the path of n'iovement of the next advancing tooth or projection 1T.

ln order to prevent displacement of the detector 155 by a retrograde movement of the disk 16 through the medium of the handle 12, the free extremity of the detector is adapted to move between guides or projections 2-1 which extend laterally from any suitable support, preferably the plate 13 as shown more clearly in ltig. 2.

Connected for operation with the check conveying disk 13 is a commodity receptacle which may be of any desirable contigui-ation but preferably in the form of a horizontally disposed drum provided with pockets 2G, and this drum is rotatably supported at one end in any suitable manner and at its other end is provided with a tubular extension 2 which terminates adjacent the rear face of the plate 10. This tubular extension 2T is adapted to receive the extremity of a shaft or axle 28 which projects laterally from the disks 13 and 1G. ik ratchet wheel 29 is secured to the extension 27 of the receptacle and this ratchet wheel is provided with notches or recesses 30 opening through the periphery thereof and the bottom of these notches or recesses are also provided with additional notches or recesses 31 opening through the periphery. Any number of the notches or recesses 30, 31, may be provided but there is j neferably provided one pair of each of the pockets 2G of the commodity delivering receptacle 25. The receptacle 25 .is connected to the check conveying means for operation thereby by means of an elastic member 32, preferably in the form of a coil spring. This elastic member surrounds the tubular extension and the adjacent portion of the shaft or axle 28 and also a lug or projection 33 on the ratchet disk or wheel. 29 and a similar lug or projection 3l. on the disk 1G so as to be supported and held in position. One extremity of the elastic member 32 engages a lug or projection 3G on the disk or ratchet wheel 29 and the other extremity 3T of the elastic member engages a similar lug or projection 3S on the disk 16. The elastic member is so arranged that when the receptacle 25 held against rotation, and the handle 12 is rotated in a clockwise direction, it will be wound to create a tension thereon.

Any suitable means may be provided for retaining the receptacle 25 and the disk or ratchet wheel 29 against rotation during the initial advancement of the check conveying means or disk 13 so that a tension will be 95 created upon the elastic member. A suitable and etlicient means for accomplishing this result comprises a retaining dog or pawl 39 which is pivotally supported by one extremity as at ett). The other extremity is preferably provided with a lateral projection Ll1 which is adapted to enter the recesses 30 and 31, in the disk 29. This retaining dog or pawl is also provided with a lateral projection or ear L12 which is preferably located adjacent the free extremity thereof and extends from the side of the dog or pawl opposite to that from which the projection -1-1 extends. The dog or pawl is so located that the projection l2 will stand in close proximity to the free end of the detector 18 and extends across the space between the plates 10 and 15 (as shown more clearly in Fig. 7) so that the edge of the check 2li will engage the projection 42 just after the check has moved the shoulder 3 of the detector 18 out of the path of move ment of the advancing projection 17 on the disk 1G, so as to rock the dog or pawl 89 about its point of pivotal support l() to move the projection 11 thereon out of the notch or recess 31 in the disk or ratchet wheel 29. As the check engages the projection ll1 on the dog or pawl 39 it will rock the latter against the tension of the elastic member 18 to release the receptacle 25.

During the advancement of the check conveying disk 13 in a clockwise direction, from the point at which the check 2-l is dcposited thereon until the edge of the check engages the projection 42 on the dog or pawl 39, the spring or elastic member 32 will be wound or a tension will be created thereon owing to the fact that one end of this elastic member and the disk 29 is locked against rotation. After the check has shifted the dog or pawl 39 to release the disk 29 and the receptacle 25, the tension which has thus been created on the elastic member 32 will snap or move the receptacle 25 forwardly at a greater rate of speed than the advancement of the check conveying disk 13. The receptacle will continue its independent advancement under the inliucnce of the elastic member 32 until a lug or projection 44 on the disk or ratchet wheel 29 and which projects laterally therefrom, engages an arm or extension 45 which is secured for rotation with the axle 28, when such independent advancement of the receptacle will be arrested. This projection 44 will engage the projection 45 at a time when the check has passed beyond the beveled projection 21 on the detector 18 so that the check conveying disk 13 will be locked against retrograde movement, and at a time when the projection 41 on the dog or pawl 39 enters one of the recesses 30 which will also lock the receptacle 25 and the ratchet wheel or disk 29 against retrograde movement. As the handle 12 is further moved in clockwise direction, the check will be further advanced by the disk 13 and will fall from the pocket 14. The receptacle will be further advanced by the elastic member 32 until the projection 41 on the dog or pawl 39 enters the recess 31 and the receptacle will then be locked in position to receive another supply. The lug or projection 44 on the disk or wheel 29 also cooperates with the arm or projection 45 to limit the retrograde movement of the handle 12 and the check conveying disk 13 and also serves as a means for positioning the pocket 14 to receive the check.

In the event that the elastic member 32 fails to operate to snap or move the receptacle 25 forwardly to discharge the commodity when the receptacle is released, a projection 46 similar to the projection 44 may be provided on the disk or ratchet wheel 29 and is arranged to be engaged by the arm or projection 45 after the check detector 18 has been shifted, so that it will start to move the disk or wheel 29 and the receptacle 25 forwardly. v

rIhe arm or projection 45 may be formed in any suitable manner but is preferably formed integral with the disk 18 which latter is preferably formed of sheet metal cut out so as to form an extension which is adapted to be bent to form the lateral projection or arm 45 and is also cut out so as to form the peripheral projections 17.

As the material is discharged from the pockets 26 vof the receptacle 25 it may be delivered to the customer through a delivery chute 47. In order to prevent the check 24 from being wedged into the pockets 14 when it engages the detecto-r and the dog or pawl 39 and in order to furnish means for ejecting the check from the pocket after it has passed these two elements, a pin or projection 48 may be provided, which preferably projects laterally from the plate 10 and eX- tends into the pockets 14 adjacent the bot-x tcm thereof and at a point in proximity to the point where the check engages the detector and the dog. When the check is advanced in a clockwise direction from the position shown in Fig. 5, the edge of the check will engage the projection 48 justas it engages tlie dog 39 as shown in dotted lines in F ig. 5 and the check will thereby be prevented from becoming wedged into the pocket as it engages and rides over the projection 48, which latter also serves to eject the check.

With this improved construction it will be apparent that immediately upon the receptacle 25 becoming released or unlocked, the elastic member will force the same forwardly so quickly that it will be almost impossible to arrest its forward movement and the receptacle will be locked against retrograde movement before the check is discharged from the check conveying disk, while at the same time the check conveying disk will also be locked against retrograde movementafter it has passed or partially passed the detector.
