7 Claims. 1

This invention relates to a cash box for use incheck operated machines. More specifically, it relates to a container which is opened as it isinserted in the machine, and held open during the time it is in the machine to receive the coins inserted butv is closed incidental to the operation of removing. the box.

I-tfihas long been a problem in coin collection to prevent unauthorized. removal of'coins from atcollect'ion box by the person who is authorized to. removethefbox. from. the vending machine or other. coincollecting machine for transportation to an accounting oihce.

The arm 55 is provided with two projections "fi i or plan View of the mecha- 5'! and 5!),of which 5! serves as a latching means, nism of Figure'ZWith the box and receiver broken 50 which are adapted t project thrgugh sk t 6| nd 63 in the rear and right end walls l3 and I9 respectively of the box;

An abutment 65 is fixed to the inside of channel 1 adjacent slot 63 in position to be contacted by the projection 59.

The projection or latching means is in alignment with a horizontal slot 61 in the back plate 3 of the receiving bracket and since the box fits slidably but relatively snugly in said bracket, the projection in certain positions of the lever 5| serves to latch the box in place.

A bracket 69 is fixed to the wall I9 of the box and lies under the arm 55 of lever 5| to assist in supporting it in alignment with the slots BI, 53 and 61.

.A spring II is attached to a depending pin 13 fixed in arm 53 and to a clip fixed to the wall |3 of the box and serves to urge the bar 5| in a clockwise direction (Figs. 3 to 6).

One edge of the arm 53 is notched at 11 so as to clear the bracket 35.

A round stop pin 19 and a square, pawl locking pin 8| are fixed to the under side of the box top l1. The pin 19 is disposed near the corner formed by the walls l3 and 2|, while pin 8| is disposed near the corner formed by wall 2| and the cover or door and with its sides at an angle to said wall and cover.

Pivotally mounted on the underneath side of arm 53 by means of a pin 83 is a locking pawl 85 which is provided with a projection 81, and an intermediate and an outer tooth or step 89, 9| respectively.

A spring 93 is coiled about pin 83 and has one and bearing on a pin 95 depending from pawl 85 and the other bearing on a pin 91 depending from arm 53.

. Operation With the coin box empty and ready to insert in theyending machine, the locking lever 5| must occupy the Figure 3 position with the projection 81 of the locking pawl disposed between pin 19 and wall l3. The lever is thus free to rotate counterclockwise aboutpivot 49 and the projection'5'l on arm 55 will enter the receiver |,,clearing the back plate 3 until it partially enters the slot 51 in said plate. The projection 59 extends through slot 63 so as to engage the abutment 65.

A firm. push to the right (Figs. 3 and 4) will cause thelever to rotate counterclockwise to the Figure 4 position by reason of the pressure of abutment 65 on projection 59. The projection 51 isin full engagement in slot 61 in this position';-the' lever has moved out from under the guide tube 4| so that the coin funnel may be inserted and theprojection 87 of pawl 85 has cleared the pin 19 and is now held with its edge against a corner of pin 8| by the spring 93. As shown in Figure 4, the shank '45 of the funnel blocks the return of the lever 5| to the Figure 3, 5 or 6 position and, consequently, prevents the withdrawal of the projection 51 from the slot 51 and-the box is accordingly locked in the case.

After the coins have been collected and it is desired to remove the coin box, it is first necessary; to remove the funnel; after which, pulling on the handle 23 will move the box to the left and spring II will rotate the lever clockwise to the Figure 5 position in which the pin 8| engages the step 9| of locking pawl 85. This is possible because the end IQ of the cash box has moved away from abutment 65.

In this position the projection 51 has not yet moved inwardly far enough to clear the back plate 3. However, it will be seen that the arm 53 has already closed the opening of tube 4|. Since the pin 8| and step 9| are engaged, it is impossible, in any way, even at this' stage, to work the arm in a reverse direction so as to open the box for the removal of money.

When the projection 51 has rotated far enough to clear the back plate 3, the lever 5| will thus be locked against reopening the coin opening.

The final stage is shown in Figure 6, in which the arm 53 is entirely over against the back plate of the box. In this position the pin 8| is engaged by the step 89 of pawl and the projection 51 is clear of the back plate 3 so that the coin box can be removed. Again, however, the opening in tube 4| is closed by arm 53 and cannot be pried or worked open.

The trick of inserting a thin strip or scale between the arm 53 and the upper inside of the tube (Fig. 3) to prevent closure of the tube is foiled because the box would, under such conditions, still be held in the receiver until the Figure 5 position is passed; consequently, even if the arm is held open, the box cannot be inverted or otherwise manipulated to remove coins.

When the box is turned over to the accounting office, an authorized person possessing the key to lock 31 will open the lock, remove cover 25, remove the coins, reset the parts to the Figure 3 position, replace the cover and lock it. The box is then again ready for installation.

It is obvious that various changes may be made in the form, structure and arrangement of parts without departing from the spirit of the invention. Accordingly, applicant does not desire to be limited to the specific embodiment disclosed herein primarily for purposes of illustration; but instead, he desires protection falling fairly within the scope of the appended claims.

What I claim to be new and desire to protect by Letters Patent of the United States is:

1. In a coin collecting mechanism, the combination of a cash box, a receiver into which said box is insertable, latching means on the box adapted to be projected to engagesaid receiver, a coin opening in said box, a closure means for said opening having effective and ineffective positions, means interconnecting said latching means and closure to hold the former projected until after said closure means is in efiective position, said latching means, when it is held projected, cooperating with said receiver to prevent withdrawal of the box therefrom, and an actuator in said box positioned to be moved by contact with said receiver when the box is inserted and connected to project said latching means and to move said closure to inefiective position.

2. In a coin collecting mechanism, the combination of a cash box, a receiver into which said box is insertable, latching means comprising a lever pivotally mounted in the box and having a projection adapted to be moved away from retracted position to engage the receiver, a coin opening in said box, said lever comprising a closure for said opening having efiective and ineffective positions, means operable by the insertion of the box into the receiver for moving said closure means to ineffective position and for moving the projection away from its retracted position, and means operable upon the withdrawal of said box from said receiver for moving said closure means from ineffective to effective position and for retracting said projection, said projection, when held out of retracted position, cooperating with said receiver to prevent withdrawal of the box therefrom.
