SHUSTOCK ZW M ATTORNEYS Unite tats atent Ofiice 3,983,896 Patented Apr. 2, 1963 3,083,896 LBCKENG DEVECE Qarmen P. (Iairelli, Farmington, and William S. Shustoclr, Newington, Conn, assignors to M. H. Rhodes, inc, Hartford, Conn a corporation of Delaware Filed May 1, 1961, Ser- No. 196,668 12 Claims. (Cl. 232-15) This invention relates to locking devices for containers or the like and is more particularly directed to a mechanism that is adapted to prevent unauthorized access to the contents of a container such as a portable coin box not only when the container is installed in an associated device such as a vending machine but also when removed therefrom.

It is an object of this invention to provide an improved locking device for a portable coin box or the like which not only is operable to lock and unlock the coin box but also is operable to secure the coin box to an associated device.

It is another object of this invention to provide an improved locking device for a coin box or other container which is operable by one operator for locking the box on and removing it from a vending machine or the like without giving him access to the contents of the box, and is operable by a second operator for removing the contents of the box.

It is a further object of this invention to provide a coin box or other container with a locking device that is operable to prevent access to the contents of the box and additionally operable to secure the coin box to another member, and wherein the box is suitably sealed at all times to prevent tampering with the locking mechanism.

It is another object of this invention to provide a coin box and coin box receptacle assembly that incorporates an improved locking means for securing the box within the receptacle, and which is sturdy and durable and has a simple arrangement of parts that are economically made and assembled.

Gther objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application which will be indicated in the appended claims.

In the drawings:

REG. 1 is a perspective view of a vending machine with a coin box and coin box receptacle assembly installed thereon;

FIG. 2 is an enlarged perspective view of the coin box and receptacle assembly of FIG. 1 showing the coin box separated from the receptacle;

FIG. 3 is a perspective view of the coin box of FIG. 2 showing the coin box closure separated from the coin box;

FIG. 4 is an enlarged side view of the coin box and receptacle assembly of FIG. 1;

FIG. 5 is a top plan section view of the coin box and receptacle assembly taken substantially along the line 5.5 of FIG, 4; and

FIGS. 6, 7 and 8 are top plan section views of the coin box taken substantially along the line 5-5 of FIG. 4 showing the coin box locking mechanism in various opcrating positions.

Referring to the drawings in detail, a coin box subassembly, generally designated by the numeral 8, is adapted for installation within a receptacle or case 10 that can be secured to a vending machine 12 or the like as by screws or rivets extending through the apertures 14 (FIG. 2). The coin box subassembly 8 is retained in the case 10 by the cooperation of the studs 18 fixed to opposite sides of the coin box 8 and the L-shaped slot 20 in the case, and can be easily assembled therein by merely inserting the box 8 horizontally into the case and then lowering it so that studs 18 are received within the vertical slot portions 21 for restricting movement of the box to the upward direction. With the coin box so assembled, a coin slot 28 extending through the coin box cover 22 is located beneath a coin funnel fixed to the case 10 .and is thereby positioned to receive coins directed to the funnel from the vending machine coin operated mechanism (not shown).

As best seen in FIGS. 4 and 5, upward movement of the coin box 8 Within the case 10 can be prevented by extending a bolt 32 mounted within the coil box subassembly into a slot 34 in the receptacle 1d thereby locking the coin box in the case. After the bolt 32 is retracted from the slot 34, the box 8 is easily removed by lifting it upwardly and outwardly for guiding the studs 18 out of the slots 20.

Referring to FIG. 5, the bolt 32, a bolt latching mechanism comprising a bolt latch 40 and a latch biasing pawl 42, and a coin slot blocking lever 38, all stamped sheet metal parts, are mounted for movement between the inside surface of the coin box top 23 and a plate 36 spaced parallel thereto. Leaf springs 44 and 46 are provided to bias the pawl 42 and the blocking lever 38 against the latch 44 and the bolt 32, respectively, and a number of rivet pins 48 extend from the top 23 to the plate 36 to secure the plates to the cover and for guiding the parts located therebetween. The cover 22 is hinged to the coin box container by the reception of the cover hinge tabs 31 (FIG. 2) in the apertures 25 (FIG. 3) and can be pivoted to close the container opening and to position the peripheral depending cover flange or edge 2? about the sides of the container. The cover 22 can then be locked on the coin box container by extending the bolt 32 under an L-shaped catch 54 secured to the inside of the box container side 27 (FIG. 3).

The bolt 32 has three functional positions; a fully extended position, shown in FIG. 5, for locking the cover 22 to the box container and for locking the coin box subassembly 8 to the case it); a partially retracted or intermediate position, shown in FIGS. 6 and 8, for looking the cover to the box container; and a fully retracted position, shown in FIG. 7, for allowing removal of cover. A pair of rivet pins 43 extend through bolt slots 47 and 53 to guide the movement of the bolt between these positions and to provide limit stops therefor. For assisting in maintaining the bolt in a selected position, there is provided a detent mechanism (FIG. 5) having a button 45 upstanding from a resilient finger 41 formed from the plate 36 by a U-shaped slot 43. The button 45 is adapted to resiliently engage either a slot 47 or one of two apertures 49 and 51 in the bolt 32 when the bolt is in the three aforementioned positions.

The bolt 32 is actuated by a pin 5'7 fixed to a lever 56 that is adapted to be oscillated by a two-key operated necting the lock and the bolt and positioning the bolt in its intermediate position when the lock is in its first position and positioning the bolt in its extended and retracted positions when the lock is in its second and third positions, respectively.

3. The combination defined by claim 2, further comprising, a bolt latching means preventing movement of the bolt from the intermediate to the extended position after it has been moved from the extended position and until it has been moved to the retracted position.
