United States Patent 3,333,764 DOUBLE LOCK COIN BOX FOR VENDING MACHINES Kit E. Pennell, Independence, Mo., assignor to The Vendo Company, Kansas City, Mo., a corporation of Missouri Filed Feb. 1, 1966, Ser. No. 524,273 3 Claims. (Cl. 23215) This invention relates to improvements in theft-proof vending machine coin boxes which are utilized to retain a reserved percentage of the machine proceeds for the owner of the machine.
In vending machine installations where the proprietor of the installation site divides the proceeds with the owner of the machine, commonly a bottling company or other product producer, a coin diverter may be provided in the coin controlled operating mechanism of the machine to automatically divide the proceeds in accordance with the particular sales arrangement. The diversion channel directs the owners percentage of the proceeds to a separate coin box provided with two key-operated locks. One of the locks is utilized to secure the box to the machine, while the other lock permits the owner to gain access to the coinage retained in the box after removal of the latter from the machine.
Vending machine owners frequently employ routemen who periodically substitute an empty box for a coincontaining box at each installation site. A routeman is given a key to the lock which permits the coin box to be released from the machine. However, the coinage is not removed until the loaded boxes are returned to the owner, who has the key to the second lock. In this manner, removal of the coinage from the boxes is under the complete control of the owner.
Although this procedure has proved to be satisfactory in practice, the coin boxes themselves present a number of problems. First, the coin entrance must be closed to prevent access thereto by the routeman once the box is removed from the machine. Secondly, some means must be provided through which the operator can render the box reusable after the coinage has been removed therefrom. Thirdly, to provide a practical unit, the box must be rug ed, relatively inexpensive, and simple to operate.
It is, therefore, the primary object of this invention to provide a double lock coin box in which access to the coinage therein through the coin entrance is positively prevented upon removal of the box from the machine, and wherein the box is rendered suitable for reuse by the operation of mechanism therein which is accessible only after the box is opened by the owner or his agents.
As a corollary to the foregoing object, it is an important aim of the invention to provide a coin box as aforesaid having a gate which shifts into blocking relationship to the coin entrance as the first lock is operated to release the box from the machine, and to provide a resettable latch which automatically holds the gate in the closed position until the box is opened and resetting of the latch effected.

The coin box of the instant invention is broadly denoted by the numeral 10 and is provided with a top 12, opposed sides 14 and 16, a front 18, a back and a bottom 21. A pair of opposed, inwardly extending flanges 22 are formed at the uppermost margins of sides 14 and 16 and overlie top 12 to provide a means of attaching the box to the housing or cabinet of a vending machine (not shown). In FIG. 5, a portion of a mounting bracket which would project from the machine housing is illustrated, and comprises a pair of angle members 24 which present outwardly directed flanges slidably received between flanges 22 and top 12. Box 10 is of sheet metal construction, and thus is rugged and inexpensive to fabricate.
Top 12 has a rectangular coin entrance 26 therein which, when the box is attached to the machine, would be registered with a diversion channel which directs a reserved percentage of the machine proceeds to coin box 10. A gate 28 adjacent entrance 26 within box 10 is connected to a keyoperated lock 30 and is shifted thereby between a closed position blocking entrance 26, illustrated in FIGS. 2, 4 and 6, and an open position shown in FIGS. 1, 5 and 7. Gate 28 comprises an elongated, transversely arcuate plate having an outwardly convex surface 32, the ends of the plate being provided with mounting ears 34, one ear being attached to lock 30 by nut 36 while the other ear rotatably receives an inwardly projecting pin 38 rigid with back 2t). The axis of rotation of the rotatable part of lock 30 is aligned with the axis of pin 32 so that, when key 40 is inserted into lock 30 and rotated, gate 28 swings through an arc in the direction of curvature of surface 32.
A pair of lugs 42 project from one longitudinal edge of gate 28 and are received by a pair of slots 44 in an angularly disposed plate 46 underlying one side of entrance 26. Plate 46 aids in the directing of coinage into the interior of box 10 and cooperates with gate 28 to close coin entrance 26 when the gate is shifted into blocking relationship to the entrance. Note also that a locking member or bolt 48 projects upwardly from lock 30 and, when the gate is open, projects above flanges 22 as is clear in FIGS. 3 and 7. The vending machine would be provided with a slot in its housing between angle mounting members 24 through which the tip of locking member 48 would extend when the box is positioned on members 24 and key 46 is operated to open gate 28. Therefore, the box would be securely locked to the machine simultaneously with removal of the gate from blocking relationship to coin entrance 26.
A latch mechanism 59 is disposed adjacent the inner wall of back 20 and is isolated from the coinage in the box by a protective plate or partition 52 secured to pin 38 and a second, inwardly projecting pin 54 by retainers 56. Mechanism includes a latch member 58 integral with the mounting ear 34 of gate 28 adjacent back 20, a swingable latch dog 60, and a reset element 62. Latch member 58 is in the form of an arcuate plate having a radial projection defining a catch 64, and a radially outwardly spaced, arcuate component 66 defining an arcuate slot 68 between components 66 and the main portion of member 58.
Latch dog is in the form of a tab projecting from an upright plate 7 6 of generally rectangular configuration. Plate 70 is pivotally mounted on pin 54 approximately midway between the upper and lower ends of the plate, the lower end portion thereof presenting a reset element 62. A spring 72 is coiled around pin 54 and has a pair of legs bearing against side 14 and element 62 respectively, as clearly shown in FIG. 6.
Side 16 (FIG. 3) has a pair of opposed, vertically extending, inwardly projecting flanges 74 which define the longitudinal margins of an access opening, the latter being normally closed by a sliding cover plate 76 received between flanges 74 and an upright flange 78 integral with base 21 (FIG. 7), and the adjacent longitudinal edge of protective plate 52. When cover 7 6 is fully seated to deny access to the contents of box 10, the uppermost margin 80 of cover 76 is received by a slot 81 formed in the upper portion of side 16, as shown in FIG. 7.
Cover 76 is provided with an integral tab 82 having an eye 84 therein which receives a locking finger or bolt 86 extending from the movable part of a lock 88 operated by a key 90. Finger 86 is moved into and out of interlocking relationship with tab 82 upon insertion of key 90 in the lock 88 and rotation thereof.
In the discussion of the operation and manner of utiliz-ation of the inst-ant invention, it will first be assumed that box 10 has been removed from the vending machine with coinage contained therein. In such case, the positions'of the various movable parts of the structure will be as illustrated in FIGS. 2, 4 and 6. Note that gate 28 is closed and access to the contents of the box through coin entrance 26 is thereby denied. Reopening of the gate through the use of key 40 cannot be effected because latch dog 60 would engage catch 64 after the gate is shifted through a small displacement. Additionally, attention is directed "to the fact that locking member 48 of lock 30 is withdrawn; this enables the box to be removed from the machine by sliding fianges 22 relative to bracket members 24 (FIG. 5).
It will be appreciated that the coin box in the possession of the routeman is theft-proof, since the routeman is provided with key 40 only. Key 90 is in the hands of the owner or his agents and is utilized after the coincontaining box is returned to the owner. Insertion of key 90 into lock 88 and rotation thereof shifts locking finger 86 out of eye 84 to permit removal of cover 76 by sliding movement thereof vertically downwardly with respect to the orientation of the box as illustrated.
Once the contents of box are removed therefrom, the owner must then return the movable parts of the structure to positions such that the box will now be rendered suitable for reuse and subsequent reattachment to a vending machine at the installation site. This is effected while cover 76 is removed by a resetting operation to be described hereinafter.
Note that the right-hand flange 74, as viewed in FIG. 3, is provided with a notch 92 adjacent the lower end of the flange which, when cover 76 is removed, is aligned with a tab 94 integral with the lower end of reset element 62 (FIG. 4). This enables a screwdriver tip to be inserted into mechanism 50 between back 20 and protective plate 52, for the purpose of depressing tab 94 when box 16 is laid over in a horizontal position with side 14 facing downwardly. The depressing of tab 94 swings element 62 about pin 54 in a clockwise direction as viewed in FIG. 6, thereby'shifting latch dog 60 toward component 66 through the interconnecting medium of the integral plate 70. While pressure is maintained against the bias of spring '72, key 40 is rotated in a direction to shift gate 28 toward its open position, this now being possible since dog 68 is no longer in the path of travel of the catch 64. Movement of gate 28 toward the open position effectively removes latch dog 60 from the confines of slot 68 whereupon, as the dog clears the free extremity or tip of component 66, the operator will experience additional movement of element 62 if pressure is maintained on tab 94. Thus, dog 60 is ultimately shifted to a position completely clear of member 58, and held in such position by rotating key 40 in the opposite direction to swing gate 28 back to its closed position.
Therefore, after the resetting operation is completed, the various movable parts of the structure will be in the positions illustrated in FIG. 6, except for plate 70 which is now displaced in a clockwise direction from the position shown in FIG. 6 with dog 60 resting against the outer periphery of component 66.
With component 66 maintaining lat-ch dog 60 out of slot 68 against the bias of spring 72, the box may be reinstalled on a vending machine after cover 76 is replaced and locked in place. As the routeman rotates key 40 to swing locking member 48 to its upper, locking position illustrated in FIGS. 1, 3 and 7, gate 28 is reopened to permit coins to pass into the box through entrance 26. The open position of the gate and the positions of the internal components when the box is installed on the machine are shown in FIG. 5, where it may be seen that latch dog 60 now engages latch member 58 in angula-rly spaced relationship to catch 64. Dog 60 did not interlock with catch 64 upon movement of the gate to the open position as the box was locked to the machine, because the tip of component 66 and catch 64 are in substantially radial alignment with respect to pin 38 so that, as component 66 moved out of engagement with dog 60, the dog was shifted by spring 72 onto the portion of latch member 58 outside of slot 68.
The next time the vender is visited by the routeman to remove the box and replace it with an empty box, key 40 must be inserted into lock 30 and rotated in a direction to withdraw locking member 48, whereupon gate 28 is simultaneously closed. This returns dog 60 to the position illustrated in FIG. 6, thereby precluding reopening of the gate until the coin-containing box is once again returned to the owner of the machine who possesses key 90. Thus, gate 28 cannot be reopened by key 40 or the box reused until the owner has gained access to the coinage therein by removing cover 76, and has reset mechanism 50 in the manner just described.
