V iwa 1 g 26 It E 44 [IE1 g aw. i. T 6 124 I f f I 1 2 i 13 This invention concerns a collection receptacle or I vault constructiondesigned for receiving and holding cash or other valuables. The invention is particularly suited for the receipt of fares, tolls, and other fees which are accepted in large numbers from the general public by transportation systems, vending machine companies, and similar operations.
In operations of the type described, individuals deposit cash in collection structures such as vending machines'or fare collection boxes. The contents of these collection boxes must then be moved to some centralized location for counting of receipts, for deposit in banks, etc.
The collection of fares or similar payments has caused many problems, and transit systems are typical inthis regard. Handling problems have been recogniz'ed particularly in the case of large transit systems "where fares from many individual vehicles are receivedfS tandard systems requirehandling of the wise characterized by efficient operation and which includes mechanisms and a mode of operation which will discourage pilfering and schemes for cheating the system.
' Copending application Ser. No. 20,884, filed on Mar. 19, 1970 and entitled Exact Fare System" describes mechanisms which are particularly suitable for the handling of exact fare" collections. As explained in that application, a cash box is removably mounted in a fare box, and all deposits made in the fare box are automatically delivered to the cash box. When the cash box is removed, it is automatically secured against unauthorized entry. Specifically, a movable wall system of the cash box provides for automatic blocking of the discharge opening of the cash box in the course of the removal operation. This same cash box arrangement can, of course, be employed in various I systems other than transit systems, that is, wherever fares by'the operator of the vehicle in transferring the fares from the collection receptacle to coin changers or money bags. Additional handling is then required in delivering the fares to some central collection point. All of this handling takes time and, therefore, leads to additional expense. The problem is compounded where the operator, of the-vehicle. is required to makesome boxes, for example, by including means which divert coins deposited. Where the operator is required to handie :leposits, scht=;mes are devised which result in ima proper recording of amounts collected.
, Robbery also constitutes a very severe problem in any:system requiring fare collection. A bus driver, for example, is extremely vulnerable to robbery since in a matter of seconds, a robber can enter the bus and take the drivers coin changer and money bags. Since buses operate at. night-often in remote locations-it is virtually impossible to adequately protect against such occurrences.
Because of the various problems referred to, transit authorities have reverted to exact fare collections. In such a system, passengers deposit money in acollection box; however, the driver is not required to carry any change, and the money is never removed from the collection box by the driver. Accordingly, the passenger must have the exact fare in his possession or must deposit an excessamount. The most that such systems require of the driver is that a receipt be given for any excess amount deposited in which case the passenger can obtain a refund at some specified location.
Since the driver does not carry any cash for change and is not authorized to personally accept any fares, the temptation to rob the driver is removed. It is, however, desirable to provide a collection system which is othercash or other valuables are collected and are to 'b secured against unauthorized removal- I In a typical operation, each cash box is brought to a central collection area whereby the contents of the cash box can be located in a vault in an authorized fashion. It is, of course, important to provide security at thistime in order to prevent pilfering or any malfunctioning of the collection arrangement.
It is a general object of this invention to provide an improved collection receptacle or vault construction whereby valuables can be transferred from cash boxes without the danger of loss of such valuables.
It is amore specific object of this invention to provide a collection receptacle of the type described which operates in a highly efficient manner whereby securebut rapid transfer of valuables from a cash box to a collection receptacle can be accomplished.

This invention generally relates to a collection receptacle or vault construction for receiving valuables from a box in which the valuables were deposited. The collection receptacle of the invention is designedfor use with boxes of the type defining a discharge opening and having a movable wall which normally covers the discharge opening. The movable wall is secured under normal conditions so that unauthorized access to the box is avoided.
The collection receptacle of this invention includes a receiving area for the box containing cash or other valuables. The door of the collection receptacle is provided with means for engaging the cash box when the door is closed. An actuating means for these engaging means is provided so that'discharge of the contents of the cash box can be accomplished after the door is closed.
In the preferred form of this invention, the door of the collection receptacle includes a rotatable drive disc for engaging the cash box when the door is closed. A handle is located on the outside of the door for rotating the disc whereby relative movement of the cash box walls can be accomplished to thereby open the cash box discharge opening, and to thereby discharge the contents of the cash box into the vault area of the construction. v
The door includes a locking mechanism which prevents opening of the door once rotation has commenced. Specifically, a channel is provided behind a receptacle wall, and a portion of the door assembly is moved within this channel when rotation commences. The door cannot be opened when this portion of the door is rotated within the channel, and return rotation which would permit opening of the door is prevented by a pawl and ratchet mechanism mounted on the door. The mechanisn'isv will not permit return rotation until after a complete forward rotation is accomplished to achieve discharge of the contents of the cash box.
The preferred structure of the invention also includes an additional locking mechanism which prevents access to the vault area which receives the valuables discharged from cash boxes. Specifically, a shutter is normally located for blocking access to the interior of the vault area, and this shutter is locked in place. The door of the collection receptacle includes means for unlocking the shutter; however, this unlocking is only accomplished when the door is closed. Upon rotation of the mechanisms employed for discharging valuables from the cash box, the shutter will be automatically moved away from blocking position whereby the contents of the cash box will be discharged into the vault area. The shutter will then automatically return to blocking position upon return movement of the rotating mechanisms, and the shutter will be automatically locked in blocking position before the door of the receptacle can be opened.
The drawings illustrate a collection receptacle mechanism generally designated by the numeral 10. This receptacle mechanism includes a front plate 12 and a back plate 14, and the operating parts of the receptacle are mounted between these plates. For purposes of clarity, walls surrounding the plates 12 and 14 are not shownin detail. It will be understood, however, that the receptacle 10 is to be associated with a sur rounding vault structure including front wall 16, rear' tenance purposes. As shown .in FIG. 16, the receptacle is provided with horizontally disposed plates 24 and 26 secured between the plates 12 and 14 to provide for mounting of the operating mechanisms of the collection receptacle. A pair of longitudinally extending rods 28 also extend between the plates 12 and 14 to assist in securing the assembly.
The receptacle is provided with a door 30 comprising a plate 32 which is attached by means of a hinge 34 to the front plate 12. The hinge is secured by means of screws 36 having flared ends which extend within the hinge, with the other ends being pivotable within retaining blocks 38. This arrangement provides a strong hinge which resists tampering.
The door plate 32 defines a circular opening 40 and a fan-shaped opening 42 (FIG. 3). A block 44 is secured to the plate 32 with a circular opening 46 defined by the block being aligned with the opening 40. A bearing ring 48 is secured to the block within the opening 46 and the stem 50 of drive disc 52 is positioned within the bearing. A square bore 54 is defined by the end of the stem 50 whereby a handle 56 having a square projection 58 can be employed for rotating the drive disc from the exterior of the receptacle.
The drive disc is secured to the plate 32 by means of stop members 62 and 64 which are attached to the back side of the plate. These stop members include edge portions which overlap the rim portion 60 of the disc. The disc also includes a projecting portion 66, and the stop members 62 and 64 extend into the path of movement of the projection 66 whereby rotation of the disc is limited.
The front plate 12 of the receptacle defines a central opening 68 which is large enough to receive the drive disc and associated stop members 62 and 64. A notch 70 is defined by this central opening, and this notch is dimensioned to receive the extension 66 of the drive disc when the door is closed.
The cash box 72 includes a handle 74 which is lined up in the position shown in FIG. 6'when properly insertedin the receptacle. An arrow 75 is displayed on the plate 12 to assist in the alignment of the cash box. The drive disc 52 is provided with outwardly extending ridges 76 which fit around the handle when the door is closed. When the disc 52 is properly aligned so that the ridges 76 fit around the handle 74, the extension 66 of the disc will be received within the notch 70.
The notch 70 communicates with a groove 78 which is cut along the edge of the opening 68 and which extends for 135; When the drive disc is'turned, the extension 66 moves within this groove as best illustrated in FIG. 11. A pair of rollers 80 are mounted on the extension 66 to provide for smooth operation of the disc within the groove. It will be appreciatedthat when the disc is rotated in the manner described, the cash box 72 will also turn within the receptacle because of the engagement of the ridges 76 with the handle 74. 1 v
The block 44 which supports the bearing for disc 52 also providesa housing for a pawl arm 82. The arm 82 is pivotally mounted on the rear wall of the block at 84. A recess 86 is formed in the rear wall of the block, and a pin 88 has one end extending within this recess. The springs 90 and 92-have their lower ends attached to this pin with the upper ends being attached, respectively, to pins 94 and 96 located within the recess86. The arrangement is such that the arm 82-can be pivoted in either direction but will. normally be retained in the upright position because of the pulling action of the springs 90 and 92.
The pin 88 also extends on the other side of the arm 82 into the path of movement of ratchet 98 which is secured on the inside of the drive disc 52'by means of fasteners 100. As best illustrated in FIG. 8, the ratchet defines a straight edge portion 102 which is located at the same level as the upper edge as the pin 88 when the parts are in the normal position. Since the edge 102 is horizontal, this edge will pivot the arm 82 from right to left in FIG. 8 'upon rotation of the disc 52 in the direction of the arrow 104. As the rotation continues, the teeth 1060f the ratchet will sequentially engage the pin 88.
Return movement of the ratchet is prevented once the first tooth 106 passes the pin 88. This is accomplished by the fact that the grooves 108 between therespective-teeth are located at a greater distance from the axis of rotation of the disc than is the corner 110 of the ratchet 98. Accordingly, once the arm 82' is pivoted in the manner described, the arm cannot be returned to the vertically upright position until after all of the teeth have passed the pin 88. In the pivoted position, the arm 82 prevents return movement of the disc.
The number of teeth 106 is selected so that sufficient rotation will be required to accomplish emptying of a cash box. When the last tooth passes the pin 88, the arm 82 will move to the upright position. The arm will then be pivoted from left to right (FIG. 8) during the return movement of the drive disc and will not return to the normal position shown until complete return rotation of the drive disc has been accomplished.
The door 30 also carries an arm 112 which moves within an opening 114 defined by the front plate 12. An opening 116 is defined by the door plate 32, and a bolt 118 extends through this opening and is threaded into the arm 1 12 for securing the arm to the door.
In the open position, the arm 112 is retracted as shown in'FlG. 19. The enlarged end 120 of the arm limits pivoting movement of the door. When the door is pivoted to the closed position, the surface 122 of the enlarged end 120 engages the end of rod 124 and drives this rod rearwardly until the shoulder 126 passes by the end of the rod (FIG. 20). As will be explained, the rearward movement of the rod accomplishes an unlocking operation which is necessary for rotation of the cash box within the receptacle. When this rotation begins, a shutter plate 128 is moved from the position shown in FIGS. 7 and 16. A cam 130 is attached to the bottom of the shutter plate, and this cam normally bears against a roller 132 secured to lever arm 134. The arm 134 is pivotally connected to the front plate 12 at 136', and a spring 138 urges the lever arm upwardly.
The lever arm pivots upwardly when'the cam 130 is moved beyond the roller 132. This locates the cam plate 140 in the path of shoulder 142 defined by the arm 112. The notch 1440f the cam plate '140 receives the shoulder 142, this arrangement preventing opening of the door 30 once shutter 128 has been moved a suff cientdistance to, move the cam 130. out of engagement with the roller 132. v t Y The arrangement described functions as a means for supporting the end of the shutter 128 which is mounted in cantilever fashion as best illustrated in FIG. 7. Thus, the engagement of cam 130 with-the roller 132 resists forcing of the shutter downwardly as might otherwise be accomplished when the door 30 is open and when no cash box is in place.
The shutter 128 normally blocks an opening 146 defined in the bottom of cylinder 148. The cylinder 148 is attached between the front plate 12 and rear plate 14, and this cylinder provides the receiving area for a cash box 72.
A rotatable plate 150 is mounted at the rear end of the cylinder 148, and the shutter 128 is secured by means of fasteners 152 to a rim portion 154 of this plate. The cylinder 148 includes an elongated slot 156 adjacent the back'plate 14 to permit movement of the extension 154 and the associated shutter 128 relative to the cylinder. A pair of rollers 158 and 160 extend inwardly from the back plate 14 for engagement with the rim 162 of the plate 150. An extension 164 defined by the plate cooperates with the rollers to provide stop means thereby limiting the degree of movement of the plate.
A locking arm 166 is received within a notch 168 defined in the extension 154 of the rotatable plate 150. This arm is attached to the end of rod 124 so that the movement of the rod by means of the arm 112 mounted on the door will displace the arm 166 out of the notch 168. Therefore, the locking action of the arm 166 is removed only when the door of the receptacle has been closed. Accordingly, the plate 150 cannot be rotated to move the shutter 128 out of blocking position while the door is open.
The cash box 72 is of the same general construction as that described in copending application Ser. No. 20,884. The cash box thus includes an inner shell 170 defining an opening 172. The outer shell 174 of the box defines an opening 176 which is normally offset 120 from the opening 172.
The shells are normally locked together by means of a lock 180. This lock is dimensioned to be received within thecylindrical member 182 located adjacent the rear wall of the receptacle receiving area. A key is located within the cylinder 182, and this key may take different forms such as the arrangement 184 shown in FIG. 21. This key includes projections 185 which are received within the lock to set the tumblers thereby permitting relative movement of the shells.
A spring loaded cap 188 is movable within the cylinder 182, this cap normally limiting access to the key but being movable upon insertion of the lock 180 so that the key will be inserted within the lock. A pair of aligning pins 190 (FIGS. 2 and 17) extend outwardly from the plate 150 for receipt within the openings 192 defined by the outer shell 174 (FIG. 18). An additional pin 194 is mounted on the base 196 which supports the cylindrical member 182. This pin is initially received within enlarged end 198 of the slot 200 which is also formed in the outer shell. Asexplained in the aforementioned copending application, the pin 194 extends through an aligned opening in the inner shell, and this arrangement serves to maintain'the inner shell in a stationary position while the outer shell is rotated through the operation of the plate 150. The'reduceddiameter portion 202 of the pin permits receipt of the pin within the slot 200 while preventing removal of the cash box when the outer shell has been rotated relative to the inner shell. This provides an added safety feature in the event that access to the interior of the structure was secured while the openings 172 and 176 were aligned. As explained, other locking features are provided for safeguarding against such access.
A bearing 224-is provided between the .cylindrical portion 197 of base 196 and the plate 150 whereby the plate can be rotated relative to the supporting structure for the key 184.
In the use-of the construction illustrated, a cash box 72 is first located within the cylinder 148. The pins 190 and 194 require positioning of the cash box in the attitude shown in FIG. 6. This insures proper insertion of a key into the lock of the cash box, and in this connection, the cash box must be forced inwardly in opposition to the spring loaded cap 188. The necessary force is obtained when the door 30 is closed. .It will be noted that the plate 52 of the door-must be in proper alignment for locating the ridges 76 around the handle 74. When thus aligned, the extension 66 on the plate will fit within the notch 70 defined by the front wall 12.
Closing of the door causes the arm 112 to drive the rod l24 rearwardly thereby unlocking the back plate 150. The handle 56 on the.exterior of the door can then be operated to rotate the plate 52 as well as the cash box which is tied to the plate. Since the pins 190 tie the outer shell 174 of the cash box to the plate 150, this plate will also rotate for moving the shutter 128.
The ratchet 98 and pawl 82 cooperate to block the plate 52 against return rotation. In this condition, the extension 66 of the plate 52 is located within the groove 78 which prevents opening of the door. The locking action of the plate 140 on the arm 112 also insures against opening of the door.
Discharge of the contents of the cash box is achieved only when the outer shell of the cash box is turned far enough to locate the opening 176 in alignment with the opening 172 of the inner shell. The inner shell opening is automatically located in alignment with the opening 146 of the cylinder 148 when the cash box is located in the cylinder. Accordingly, the contents of the cash box will drop into a vault area located beyond the opening 146.
The length of the ratchet 98 is such that dumping of the contents from the cash box will occur before the ratchet passes by the pawl 82. Accordingly, return movement of the cash box cannot be achieved until after dumping. The return movement also results in the movement of the shutter 128back into blocking position. Furthermore, the cam 130 on the shutter 128 will drive the lever arm 134 downwardly thereby releasing the arm 112. The extension 66 on the plate 52 will move opposite the notch whereby the door can be opened, and the cash box removed.
It will be understood that various changes and modifications may be made in the above described construction which provide the characteristics of this invention without departing from the spirit thereof particularly as defined in the following claims.
