14 Claims.

This invention relates to coin receptacles and more particularly to self-locking detachable cash boxes for use with coin collectors for telephone systems.

An object of this invention is to provide a positive and simple locking device which operates upon the withdrawal of the coin receptacle from its housing to close and lock the coin opening therein.

A further object is to provide means actuated by the removal and replacement of the coin receptacle cover to unlock the shutter or closure for the coin opening therein and reset the locking device preparatory to inserting the receptacle in the coin collector.

Specifically the locking device which looks the shutter over the coin opening in its closed position comprises a spring actuated bolt which is adapted to engage a recess in the under surface of the shutter in its closed position and which upon replacing the cover is retracted by a lever cooperating with the receptacle case to release the shutter. In one embodiment the lever is pivoted and a spring operated stop latch engages the bolt to hold it in its retracted position out of engagement with the shutter and the latter operated by the insertion of the receptacle in its cas- I ing operates the latch to release the bolt. In another embodiment the latch and lever are combined in a rocking or floating lever.

The coin receptacle 1 when in position in a coin collector, not shown, which may be of any of the forms well known in the art, such for example, as that shown in Patent 1,104,042 to O. F. Fors- The cover 2 comprises an upper and a lower plate within which is located a shutter 4 adapted to rotate about a pivot 5 to close'the coin receiving opening 3. The shutter 4 is provided with a portion 19 which extends upwardly fromthe inside of the cover 2 to the outside through a slot and then laterally beyond the edge of the cover 2 as indicated in Figs. 1 and 2. Integral-with or attached to the upper side of the compartment in the coin collector, not shown, is a member 21 which is partially shown in Figs. 5 and '7. This member, through engagement with the cover 2, guides the coin receptacle 1 within the compartment in the coin collector, not shown.- At one side the member 21 is provided with an opening 22 through which the portion 19 may extend. The opening 22 is partially closed by a laterally extending pocket 23 of the member 21. The rear edge 24 of the pocket 23 is adapted to engage the portion 19 when the coin receptacle 1 is being withdrawn from the compartment provided in the coin collector to rotate the shutter 4 to a position before the opening 3 as will be hereinafter described.

On the underside of the cover 2 is a locking mechanism which serves to lock the shutter 4 in its closed position. The locking mechanism comprises a bolt 6 adapted to engage a recess '7 in the shutter 4 when the latter is in its closed position. A spring 10 insures positive engagement of the bolt 6 with the recess '7 andalso serves to retain the bolt in said recess. The resetting of the bolt 6 is automatic and is accomplished by means of a resetting lever 11 cooperating with a latch 1'7 when the cover 2 is removed from the receptacle 1. The resetting lever 11 is pivoted at 12 and comprises an arm 14 which is adjacent toand parallel to the base plate 9- of the cover 2 and extends under the head of the bolt 6. Another arm 16 extends downwardly a short distance from the pivot 12, runs parallel to the base plate 9, then extends upwardly toward the base plate 9 to end in a lip 30 which is adapted to fit on the upper edge of the coin receptacle 1 as shown in Fig. 2. The latch 1'7 which is adjacent the base plate 9 of the cover 2 is adapted to move toward the bolt 6 by means of the spring 18. A- portion 31' of the latch 1'7 extends up through an opening 32 in the upper portion of the cover 2.

When the coin receptacle 1 is ready to be inserted in the compartment provided for it in the coin collector, not shown, the shutter 4 is closed and the lock is approximately in the position shown in Fig. 6. As the coin receptacle is inserted in said compartment the portion 19 of the shutter 4 projects through the opening 22 and passes inside of the pocket 23. The projection 19 thereupon engages the rear edge of the opening 22 at 25 and as the coin receptacle is forced back into place in the direction shown by the arrow in Fig. 5 the shutter 4 is removed from before the opening 3. Upon further insertion" of the coin receptacle 1 the cam 26 on the shutter 4 engages the portion 31 of the latch 1'7 and forces the latch forwardly against the pressure of spring 18. This forces the portion 2'! of the latch 1'7 from under the head of the bolt 6 thus releasing the latter as shown in Fig. 8. The bolt 6 upon releasing bears upon the under side of the shutter 4 under the pressure of spring 10. Figs. '7 and 8 show the position of the elements when the coin receptacle is fully inserted in the compartment provided for it in the coin collector. In this position portion 19 of the shutter 4 and the pocket 23 are so proportioned that the portion 19 projects too far through the opening 22 to allow the coin receptacle 1 to be removed from the retaining member 21 unless the shutter 4 has been moved into position such that the bolt 6 will snap into the recess '7 in the shutter 4. Thus in order to remove the coin receptacle from the coin collector, not shown, the portion 24 of the pocket 23 bears against the portion 19 of the shutter 4 and forces it over the opening 3. When the shutter has closed the opening sufficiently, the bolt 6 will be on line with the recess '7 and under pressure of the spring 10 will snap therein. The portion 19 has now retired sufficiently to go through the pocket 23 and the coin receptacle may be removed from the coin collector.

After being removed the coin receptacle 1 may beopened by an authorized person. Upon removal of the cover 2, the resetting lever 11 under the action of spring 13 is forced away from the base plate of the cover. The portion 14 of the lever forces the bolt 6 out of engagement with the recess '7 of cover 4 and forces the latch 17 back against the pressure of its spring 18. When the head of the bolt 6 clears the portion 2'7 of: the latch 1'7, the latch under pressure of its spring 18 will return to its normal position, the portion 27 now being between the head of the bolt 6 and the base plate 9 of the cover 2 and will prevent the bolt 6 from reengaging with the recess '7 of the shutter 4 as shown in Fig. 4.

When the cover 2 is replaced on the coin receptacle 1, the portion 30 of the resetting lever 11 is forced toward the base plate 9 of the cover 2 against the pressure of spring 13. This pivots the lever 11 about its fulcrum 12, and arm 14 returns toward the base plateQ releasing its pressure on the underside of the head of bolt 6 as shown in Fig. 6. The head of the bolt 6 under the pressure of spring 10 then rests solely on the portion 2'7 of latch 1'7, and the coin receptacle is ready for insertion in the compartment provided for in the coin collector (not shown).

In another embodiment of this invention the resetting lever and latch are combined in a rocking or floating lever 41 as shown in Figs. 10, 12, 14 and 16. The lever 41 is so designed that a portion 42 is adapted to fit between the base plate 9 of the cover 2 and the head 43 of the bolt 6 under the pressure of springs 44 and 45 when the cover 2 is removed from the coin collector 1 as shown in Fig. 12. The lever 41 is bent at an angle of approximately sixty degrees at 46 and 4'7, the purpose of which will be later disclosed. A portion 49 extends up through an opening 50 in the base plate 9 of the cover 2 and is associated with the shutter 4 to remove the portion 42 from between the base plate 9 and the head 43 of the bolt 6. The lever 41 ends in a lip 31 which lies between the upper edge of the coin receptacle 1 and the upper plate of the cover 2 when the cover 2 is placed on the coin receptacle 1. A projection 51 extends from the underside of the lever 41 to serve as a support for the spring 44. Near the portion 42 of the lever 41 is an opening 52 through which extends a projection or pin 53 mounted on the lock casing 54. This insures longitudinal movement of the lever 41 as it is moved backward and forward. Mounted on the pin 53, between the lever 41 and the spring 45 is a latch 55 comprising projections 56 and 5'7 which snap up in front of the shoulders 58 and 59 of the lever 41 when the latter is forced away from the bolt 6 by the action of the shutter 4 on portion 49 thus preventing lever 41 from returning toward the bolt 6. Guards and 61 on latch 55 keep the latter and lever 41 in alignment. The latch 55 is also: provided with a fork-shaped end having prongs 62 and 63 which straddle the bolt 6 and bear on the base plate 9 and tend to keep the former in an approximately horizontal position at all times.

When the cover 2 is to be placed on the: coin receptacle 1 prior to placing the coin receptacle in the compartment provided for it in the coin collector, not shown, the elements are in the po sition shown in Figs. 11 and 12'. It is noted that projection 42 is between the base plate 9 and the head 43 of the bolt 6. As the cover is placed in the receptacle 1 the portion 3.1 of the lever 41 engages the end 64 of the receptacle 1 and is forced toward the. upper; plate of the cover 2. Lever 41 is thus rotated about the temporary axis 47 against the pressure of spring 45 exerted at 46 and by means of portion 42 forces the pin 6 out of the recess 7 in the shutter 4 against the pressure of spring 10' thus permitting the shutter 4 to be opened.

As the coin receptacle is inserted in the coin collector, portion 19 of the shutter 4 projects through opening 22 and passes inside of the pocket 23. The portion 19 thereupon engages the rear edge of the opening 22 at 25 and as the coin receptacle is forced back into place in the direction shown by the arrow in Fig. 13', the shutter 4 is removed from before the opening. 3'. Upon further insertion of the coin receptacle 1, the cam '70 on the shutter 4 engages. portion 49- of the lever 41 and forces the lever outwardly against the pressure of spring 44. This disengages the portion 42 from the head 43 of bolt 6 thus releasing the latter. The bolt 6 upon being released, bears upon the underside. of a casing 81 mounted on portion 82' of the shutter 4 under pressure of spring 10 as shown in Fig. 14. Upon complete insertion of the coin receptacle in the coin collector, the lever 41 is forced further from the bolt 6 and shoulders 58 and 59 of lever 41 clear the projections 56 and 57' of member 55, the latter of which under the pressure of spring 45 moves toward the base plate 9 of the cover 2 and forms an obstacle against the return of lever 41 toward the bolt 6v as shown in Fig. 14.

As the coin receptacle 1 is removedv from the coin collector in order to empty it of its con.- tents, portion 24 of the pocket 23 bears against the portion 19 of the shutter 4 and forces it over the opening 3. Cam '70 on the shutter 4 disengages from the portion 49 of lever 41, allowing the latter under pressure of spring 44 120 move toward the locking bolt 6. When the lever has moved sufficiently, the shoulders- 5.8 and 59 engage projections 56 and 57 on member 55 and prevent further movement of the lever. When the shutter has closed the opening sufficiently, the bolt 6 will be on line with the recess 7 and under pressure of the spring 10 will snap therein as shown in Fig. 10. The portion 19 will now be allowed to go through the pocket 23 and the coin receptacle may be removed from the coin collector.

After being removed the coinv receptacle 1 may be opened by an authorized person in the usual manner. Upon removal of the cover 2 spring 45 exerts an upward pressure at. 46 andv the lever 41 which has been released from the top 64 of the receptacle 1, swings about 47 as a pivot. causes portion 42 to approach the base plate 9 of the cover 2, disengages the shoulders 58 and a shutter on said cover 59 from the projections 56 and 57 and allows the lever- 41 when these obstacles have been removed to be. moved toward the. bolt 6. under pressure of spring 44. Springs 44 and 45 cooperate to force the portion 42: between the head 43 of the bolt 6 and the base plate 9 of the cover 2- as shown in Fig. 12. The locking mechanism has thus; been automatically set sothat when the cover 2- is replaced on the coin receptacle 1, the lock will be automatically reset for reinseition in the coin collector. Thus portion 31 will engage with portion. 64. of the coin receptacle 1, swinging the lever 41 about 47 as; a pivot and disengaging the bolt 6 from recess 7 by the downward movement of portion 42: as explained before.

Applicant in this modified structure has also provided two safeguards which render it impossible for an unauthorized person to purloin the contents of the coin collector.

The first of these is a floating washer loosely mounted on the. upward projecting portion 91 of the base plate 9 which acts as a guide for the bolt 6. Surrounding the washer 80 is a casing 8i provided on portion 82 of the shutter 4 which is of such length as to permit the shutter to open and close. An opening 83 in the bottom of portion 82 is provided for the bolt 6. Thus, while the shutter 4 is being opened. or closed, casing 81 moves with the shutter 4 while bolt 6' and washer 80 remain in approximately the same position. By means of. this structure, fraudulent attempts to prevent bolt 6 from engaging recess 7 are rendered impossible.

The second safety feature in this device is a means to prevent the reopening of the shutter 4 after opening 3 has closed a certain extent while the coin receptacle 1 is being withdrawn from the coin collector. This is accomplished by an auxiliary recess adjacent recess 7 which is so posi-tioned that bolt 6 engages it when the shutter is in the position shown in Fig. 15. The small portion of opening. 3 that is left uncovered is too small to allow even theextraction of a small coin. Under normal conditions, upon further closing of the shutter preparatory to its being withdrawn from the coin collector, the bolt 6 will snap into recess 7 and the shutter will be locked in its fully closed position.
