MONEY BOX CONSTRUCTION Filed Oct. 28, 1964 7 Sheets-Sheet 7 INVENTOR. MITCHELL A. HALL Y, -Q-f 240 BY 1 206 202 4, ATTORNEY United States Patent 3,276,835 MONEY BOX CONSTRUCTION Mitchell A. Hall, 445 Rossford Ave., Fort Thomas, Ky. Filed Oct. 28, 1964. Ser. No. 407,112 28 Claims. (Cl. 312-333) This invention relates to a money box construction, of the type suited for use in accumulating coins from the coin chutes of dispensing machines; laundry service machines, coin telephones, and similar coin-operated devices. Such money boxes are adapted to be locked to a rigid frame fixed within the casing of the dispensing or service machine, so that removal of the box and contents from the machine casing may be achieved only by an authorized person in possession of a proper key. Such person may thereby remove a box containing accumulated coins, and substitute therefor an empty box. The box removed will ordinarily be forwarded to a coin-counting oflice.

In some instances, it may be desirable to provide the money box with a detachable lock-unit, so that the box of coins removed from the machine may be forwarded to the counting oflice with the lock-unit detached therefrom. The detached lock-unit may under such circumstances be applied by the serviceman to the empty replacement box, thereby to avoid the forwarding of lockunits to the counting ofiice. Such procedure keeps the lock-units in constant service, and may be of advantage for accounting purposes.

An object of the present invention is to provide an improved locking and bolting mechanism for money boxes and the like, which effectively defies pilfering even though the attempt may result in severe mutilation or destruction of the locking mechanism.

Another object of the invention is to provide in a money box construction, a simplified and highly effective means for maintaining a bolted affixation of the box to a stationary frame, in defiance of unauthorized removal by drilling of the lock or other elements of the lock-unit, or by driving the lock from normal position within the unit.

A further object is to provide in a device of the character stated, means for facilitating and expediting the exchanging of lock-units on money boxes, and in the alternative, effecting a simple semi-permanent afiixation of the lock-unit to a box.

A still further object of the invention is to provide means in a device of the character stated, for the multiple bolting of a door to a supporting frame with maximum ease and ample security.

The foregoing and other objects are attained by the means described herein and illustrated upon the accompanying drawings, in which:

In the drawings, FIGS. 1 to 4, the numeral 30 indicates a sheet-metal money box, having a lid 32 apertured at 34 to receive coins released from a coin slide (not shown). The lid aperture may be furnished with a hinged closure member 36, which may be closed and sealed when the box containing a quantity of coins is to be separated form its supporting frame 38 and forwarded to a coin counting office. Frame 38 is a stationary element fixed securely within the cabinet or housing of a dispensing machine or the like.

Coin box 30 carries a lock-unit 40 (FIG, 5), which normally is fixed to the box, but which may quickly be detached therefrom after the unit is unlocked from frame 38 to penmit withdrawal of the box from frame aperture 42. Detaching the lock-unit by the Serviceman enables him to apply the same lock-unit to an empty replacement box which replaces the one removed. The box removed may therefore be transported to the coin counting otfice, relieved of the weight and bulk of the lock-unit.

The lock-unit may comprise a flat door or front plate 44, and a permanently mounted boltwork housing 46 which may be welded or otherwise secured to the rear face of the door. A lock case 48 fixed to housing 46,

, extends through a central aperture of door plate 44 and may accommodate a key 50 for extending and retracting the multiple bolts 52. The bolts may be projected through upper, lower and side openings 54 of housing 46, to engage a hard steel flange 56 applied to frame 38 marginally of aperture 42, for bolting the lock-unit and accompanying coin box to the frame.

of one or more springs.

FIGS. ,5, 6, and 7, show the lock-unit separated from the coin box, by means of a quick-detachable connection. As shown, lock-unit, or boltwork housing 46 is provided with pairs of fixed lugs 58, which extend inwardly from opposite sides of the housing. The lugs are engageable by depending hooks 60 carried by the coin box, so that the box normally hangs on the lugs. To effect a connection, it is necessary only to insert the lugs 58 of the bolt housing behind the hooks 60 of the coin box, so that the box hangs from the lugs. Detachment involves lifting the box sufficiently .to disengage the books from the lugs, and then moving the box away from the lockunit-as in FIG. 5.

To avoid inadvertent separation of the coin box from the lock-unit, the box may be provided with a leaf spring latch 62 having a hooked end 64 to engage an upper lug 58 upon assembly of the look-unit upon the .box.

The spring latch may be accessible through an opening 66 in one side of the box, so as to be manually flexed for disengaging the hooked end 64 from upper lug58,

thereby to free the lock-unit for detachment from the coin.

holes 70 incident to detachment of the lock-unit from the box. The pimples 68 and holes 70 constitute friction detents which are readily separable.

In the event that a semi-permanent connection between the lock-unit and coin box is desired, a screw 72 may be inserted through an opening 74 in the -bolt housing, to engage a threaded hole 76 in hook flange 78. Removal of the screw permits detachment of the lock-unit from the coin box. Screws such as 72 may be applied at opposite sides of boltwork housing 46.-

The reference numeral 80 indicates a laterally swingable latch to engage beneath the upper flange 82 of boltwork housing 46, to hold lid 32 in closed position while the coin box is attached to the lock-unit. The front wall 84 of the coin box may be provided with a depression 86 to accommodate the inner end portion of lock 48, if necessary. Front wall 84 is a permanent element of the coin box, applied in any suitable manner; and lid 32 may or may not be hinged upon the box, as desired. A separable hinge is shown at 88-90, FIGS. 6 and 21.

The details of the boltwork are illustrated by FIGS. 9 to 13, inclusive, wherein the numeral 52 indicates a plurality of bolts which may be extended through slots 54 in boltwork housing 46, to engage the flange 56 of frame 38 serving as a keeper. Bolts 52 may be in the form of protuberances fashioned on a pair of bolt plates 94 and 96, hinged at 98 and 100 upon housing 46. Each bolt plate may be in the shape of a bell crank as shown in FIGS. 11 and 12, and the divergent arms of each bell crank may carry one or more bolts 52. Each arm carries two bolts in the example illustrated.

Referring to FIGS. 11 and 12, it is apparent that slight movement of a bolt plate in one direction about its pivot 98 or 100, may extend the bolts 52 through slots 54 as in FIG. 11, to lock the boltwork housing 46 relative to flange or keeper 56. Conversely, movement of a 'bolt plate in the opposite direction about its pivot will vretract the bolts, as in FIG. 12, so they will clear the keeper and thereby permit withdrawal ofv the coin box from the frame aperture 42, according to FIG. 2.

Bolt plates 94 and 96 are constantly yieldingly urged outwardly to extend their bolts 52, preferably by means Inthe example illustrated, a single spring 102 is employed, operative to extend both bolt plates 94 and 96. Spring 102' may be in the form of a resilient arched wire having opposite ends thereof box.

4 impinging against lugs 104 formed on the bolt plates, to constantly yieldingly urge the plates in opposite directions about their respective pivots 98 and 100.

Key lock 48 has a central shaft 106 to which is fixed, as by means of a nut 108, a yoke 110 which includes a pair of legs having slots 112 formed in the free ends thereof. The slots are loosely receptive of a pair of lugs 114 which extend from one face of a flat cam disc 116, which disc is centrally apertured at 118 for rotation about a hub 120. The hub concentrically surrounds the threaded lock barrel 122,. and may be fixed to the barrel by means of a nut 124 and washer 126. Thus, whenever the lock shaft 106 is rotated by means of a proper key 50, yoke 110 will drive the cam disc 116 by reason of the connection 112-114.

Cam disc 116 has formed therein a pair of spiral cam slots or tracks 130, and each track slidingly accommodates a follower 132, said followers being in the form of lugs formed integrally upon the bolt plates 94 and 96. Thus, rotation of the cam disc enforces movement of followers 132,132, toward and from shaft 106, to

retract and extend bolt plates 94 and 96, and their several bolts 52. a

The gradual long slope and short throw of cam tracks 130, ensures easy manipulation of the door bolts by means of key 50. Noteworthy also is the fact that follower lugs 132 engage the cam tracks at right angles to the plane of the cam disc 116, and will therefore readily leave the tracks in the event that a thief drives the lock forcibly through door 44 in attempting to gain access to the coin Displacement of the lock and cam disc 116 rearwardly, will result in freeing the followers 132 from the cam disc, whereupon spring 102 will effectively maintain an extended or operative condition of all the bolts 52. Also, if driving of the lock displaces yoke 110 to destroy .the connections at lugs 114, cam plate 116 will be immobilized in the bolted condition of the door. The spring 102 insures, further, a bolted condition of the door even though the thief may resort to drilling the door or the lock in various ways. Note also that bolting occurs all around the perimeter of the door, or along four sides thereof.

It may here be noted that with only slight modification, the lock and boltwork above described may be applied to doors which are circular, rather than rectangular, while preserving all the advantages above referred to. In the case of a circular door construction, the coin box may be either rectangular or cylindrical in shape, with corresponding modification of the shape of frame aperture 42.

FIGS. 14 to 24, inclusive, illustrate a modification of the boltwork, and of the means employed to mount and demount a lock-unit relative to a coin box. The coin box in this instance has an opening 136 in the rear wall thereof, aligned with an internally threaded nut 138 carried by a portion 140 of frame 38, for reception of an elongate threaded bolt (not shown), which normally ties the box to the frame. This constitutes old practice which forms no part of the present invention, and should therefore be ignored as the tie mentioned will not be used in conjunction with the present invention.

The sheet metal box, FIG. 15, carries a pair of forwardly extended arcuate arms or wings 142, which may be formed integrally with the box sides. The armsare capable of slight outward flexion to the extent of the in-. herent resiliency of the metal sides. Said arms are adaptedto snap over and embrace a pair of spaced parallel posts 144 on lock-unit 40, FIGS. 22, 23, 24, for detachably mounting the lock-unit by means of rearwardly extending lugs 146 struck from a bolt housing plate element 148 (FIG. 16) which element 148 may be spotwelded against the back of door 44. The same posts 144 are adapted to pass through perforated lugs 150 of a second housing plate member 152,;for supporting the latter in spaced parallelism with plate member 148. The

space between members 148 and 152 accommodates the bold elements 154 for extensile and retractile movement about pivots 156, 156.

The upper pair of lugs 150 may be provided with depending hooks 158 to engage the upper edge of box front 84, so that the lock-unit may hang from the box. The box lid may be cut away at 160, 160, to permit engagement of books 158 with the upper edge of the box front wall. The lower lugs 150 need not carry hooks such as 158. FIGS. 22 and 23 indicated how the lockunit may be applied to and detached from box 30, by tilting one part relative to the other. FIG. 24 shows the arms 142 yieldingly embracing the posts 144 to hold the parts in the FIG. 22 position.

Referring to FIGS. 16, 17 and 18, it is noted that lock 48 comprises an externally threaded body 162, and a shaft 164 which may be rotated upon insertion of a proper key into the lock. Lock body 162 fits snugly within an aperture 166 of plate 148, and extends also through a central aperture 168 of plate 152. Plates 148 and 152 may be spaced apart by a washer 170, which maintains clearance for movement of bolt members -154, 154 between the plates. The bolt members may be of hell crank formation as shown, with holes 172 provided for pivotal connection with pivot members 156.

Corresponding arms 174, 174 of the bolt members carry lugs 176, 176 which extend in a common direction at right angles to the bolt members. These lugs are cam followers, which extend through apertures 178 in plate 152 to engage cam slots or tracks 180 of a cam disc 182. The central bearing 184 of the cam disc rides upon hub 186, and a nut 188 threaded onto the lock body holds the cam disc in place upon the hub.

To the outer end of lock shaft 164 is fixed a cap 190, secured by means of a nut 192. The cap has a driving connection with cam disc 182, consisting of an outstanding lug 194 on the disc loosely received in a notch 196 of the cap, whereby rotation of lock shaft 164 and cap 190 is imparted to the cam disc. It will be understood that rotation of the cam disc by shaft 164, with followers 176 riding in cam slots 180, enforces movement of bolt members 154 about their pivots 156, to extend and retract the bolt members into and from locking engagement with the flange 56 of frame 38, FIG. 14. Both legs of each bolt member may engage flange 56 when the bolt members are extended (FIG. 18).

With reference to FIG. 15, the coin box wall 84 is recessed at 86 to accommodate cap 190. Should a thief drive the lock through door 44 and thereby displace cap 190 away from cam disc 182, the connection at 194196 would be broken so as to prevent any subsequent rotation of the cam disc, and consequently, prevent withdrawal or retraction of the bolt members from operative position. The bolt members may be spring-loaded as suggested at 199, to urge the bolt members constantly toward locking position.

It will be apparent by referring to FIGS. 16, 17, 18, that drilling the door or the lock in an attempt to gain access to the coin box, cannot successfully be accomplished. Neither will destruction of the lock afford any advantage in the attempt to pilfer the coin box. In FIG. 14, the reference numeral 198 denotes a flanged aperture of frame 38, through which coins may be guided from one or more coin slides to the coin box aperture 34. Suitable coin slides may be supported by the upper apertured portion of frame 38.

In the modification, FIGS. 25, 26, 27, the housing 200 for bolt members 202, 202, is welded or otherwise fixed to the back of door 44, and has top and bottom flanges 204 and 206 flanked by opposed side flanges 208 which may be integral with a back wall 210. The side flanges and the bottom flange may carry inwardly directed hooked lugs 212, to engage slots 214 of the coin box walls in detachably mounting the lock-unit upon the coin box. As FIG. 27 clearly indicates, the sides of the coin box may be flexed inwardly, as at 216, to facilitate attach ment and detachment of the lock-unit.

locking connection one with the other The top and bottom flanges of the boltwork housing may be provided with elongate slots 218, through which the bolting portions of the bolt member 202 may be extended and retracted. The bolt members in this instance are' bodily slidable in opposite directions within a common plane, while resting flatwise against the back Wall 210 of the housing. The door and the back wall are apertured as at 220 to accommodate the threaded body 222 of lock 48, and a nut 224 engaging the threads of the lock body holds the lock in fixed position thereon. The bolt members may be recessed at 226 to avoid interference with nut 224 as the bolt members retract.

The lock has the usual shaft 228 to be rotated upon insertion of a proper key into the lock, and upon the end of the shaft is secured a cam disc 230, preferably by means of a nut 232. The cam disc may be provided with an extended hub 234 centrally apertured to receive lock shaft 228, and about the hub may be located the spiral cam slots or tracks 236..

The spiral cam slots or tracks 236 loosely receive the extending followers or studs 240 which are fixedly secured to the bolt members, so that rotation of the cam disc in opposite directions by means of a key inserted in lock 48, will serve to extend and retract the bolt members through the slots 218 of housing 200. FIG. 26 shows the bolt members 202 fully retracted (full lines), whereas the broken lines 242 shows the bolt members extended so as to engage a flange 56 of frame 38. The two bolt members, if desired, may be spring-urged toward the locking or extended position, as suggested in the description of FIG. 11.

In all forms of the device herein disclosed, the lockunits for the coin boxes may be separated from the boxes with great ease and dispatch, and re-assembly is just as readily achieved. The ability to gather coin boxes from the machines which they serve, and to convey or forward the coin boxes without lock-units attached, is of great advantage. The weight of the shipment is thereby substantially reduced, and a minimal number of lock-units is needed since all the lock-units on any given service route are kept in constant use.

The lock-units per se incorporate several important improvements, which as previously explained, greatly enhance ease of bolt manipulation, and promote maximum security against pilfering of the coin boxes. The assembly of box and lock-unit eliminates accessibility of parts vulnerable to removal or disassembly, and precautionary measures are employed to foil any attempts to gain access to the coin receptacle by drilling the lock or the door front, or by driving the lock from the door of the receptacle. The door in each embodiment of the invention may be constructed of tough stainless steel if desired, and tough steel may be employed in constructing other vital elements of the assembly.

It is to be'understood that various modifications and changes may be made in the structural details of the device, wit-hin the scope of the appended claims, without departing from the spirit of the invention.
