, Harry Greenwald ATTORNEY United States P e com DRAWER WITH INTERCHANGE'ABLE LOCK BOLT Harry Greenwald, Brooklyn, N.Y., assignor to H. Green- Wald & Co. Inc., Brooklyn, N.Y., a corporation Filed Oct. so, 1958, Ser. No-170, 6-s7 3 Claims. 01. 232-4 vice causes the coin to fall through a discharge chute into a locked coin drawer or receptacle. These receptacles are emptied periodically by a collector having a key to the coin drawer or receptacle. To keep the operatingand maintenance costs of such devices at a minimum, it is desirable to expedite and simplify the collection operation as much as possible so as to permit each collector to service as many devices as possible. This, in turn, reduces the collection labor cost per unit.

These objectives are attained by a coin chute in the form of a rectangular cross-section metal tube having a mounting plate for securing it to its appliance. A forward wall of the chute has a narrow slot extending there across adjacent its lower end and aligned with a similar slot in the opposite or rear wall, and a square metal ring may be welded to the inside of the tube below the slots. and with its upper edge flush with the lower edges of the slots. -An angularly olfset plate is welded to the rear wall above the slots and has an inwardly offsetend extending generally parallelto said rear wall toward the slots. This offset end is formed to act as a keeper for the locking bolt of the coin drawer.

The coin drawer is a plate bent to form perpendicularly related bottom and front walls. The bottom wall has a width substantially equal to the inside width of the chute and a length such that, when the coin drawer front wall engages the chute front wall, the bottom wall extends at least fully into the slot in the chute rear wall. This bottom wall may have an ear or abutment for engaging the chute side wall to limit inward movement of the coin drawer.

The front wall of the drawer carries a key operated lock having a body extending through an aperture in the chute front wall, and the key rotates a locking bolt projecting toward the keeper plate on the chute rear wall. These locking bolts have ends cooperable with either a nut on the keeper plate or a double keyhole aperture in the latter.

Due to the differences in the latching ends of the two types of bolts, it has heretofore been necessary to provide the coin chute with a keeper plate designed to cooperate with the particular type of bolt provided on the coin drawer, and coin drawers with different types of bolts could not be used interchangeably with a given coin chute. This has necessitated maintenance men keeping on hand both types of coin drawers for any needed replacements, which results in increased stock expense as well as increased replacement time in finding out which drawer to use with a particular coin chute.

In accordance with the present invention, these difficulties are avoided in a novel manner by threading the central hole of a keeper plate provided with a double Patented May 9, 1961 ice keyhole type of latch opening. These threads mate with those on a latch bolt having a threaded end, and thus the. keeperplate is cooperable with either type of latch bolt. As a consequence, the maintainer need carry only one type of coin drawer, thus reducing the number of drawer stock required. Also, the installation time is re duced as either type of drawer will fit a coin chute provided with a latch plate embodying the invention For an understanding of the invention principles, reference is made to the following description of typical embodiments thereof as illustrated in the accompanying drawings. In the drawings: 7 a r I i Fig. 1 is a part sectional and part front elevation view of a coin chute and coin drawer embodying the invention; 1

Fig. 2 is a transverse sectional view of the chute, taken on the line 22 of Fig. 1; t

Fig. 3 is apartial side elevation View of the lower end ofFig.1;

Fig. 4is a partial front elevation view of the chute with the coin drawer removed; l

Fig. 5 is a sectional view on the line 5-5 of Fig. 1, one type of-coin drawer being shown in elevation;

Fig. 7 is a side elevation view of the coin drawer showing a-locking bolt having a pinned end cooperable with the double keyhole slot; and

Fig. .8 is a similar view showing a screw type of locking bolt cooperable with the threaded central hole.

Referring to Figs. 1 through 6, a typical coin chute 1 0 usable with the invention is a rectangular cross-sectron metal tube formed by bending a strip of metal to the desired shape and with a reinforcing plate 11 welded over the meeting edges of the strip to closethe slot 12. The upper edges of front wall 13 and rear wall .14 are flangedforwelding to mounting plate 15 which may be bolted or otherwise secured to the wall 16 of a coincontrolled appliance. Below plate 15 are the usual interference bafiles 17. y Y i Just above-the lower edge of tubeor chute 10,front wall 13 and rear wall 14 are formed with transversely aligned

slots

21 and 22, respectively, extending partly mto the chute side walls. A square metal ring 23 is welded into chute 10 below the slots and with its upper edge flush with the lower edges'of the slots. An angular remforcing plate 20 has a wall 24 overlying the side wall opposite strip 11 and a wall 26 overlying part of front wall 13. Plate 20 is welded to chute 10 and augments the reinforcing action of strip 11. For a purpose to be described, the edge of wall 26 is concavely curved as illustrated at 27.

Just above

slots

21, 22, a keeper plate 30 embodying the invention is mounted on rear wall 14. Plate 30 has wall 42 has a width just less than the inside width of edge 27 of reinforcement memberv 20. The front wall of drawer 40 is 'apertured to receive a lock cylinder 44 operable by a key 45. This lock cylinder is firmly secured in wall 41 andprojects through aperture 36 when drawer 40 is in position. v

.When key 45 is inserted into-lock cylinder 44, it is efiective to rotate a'stub shaft 46 on which ,is. secured a sleeve .47.v This sleeve is provided with s'etscrews;48 for interchangeably securing

extension shafts

50 or 60 in the sleeve. Washers 49 may be interposedbetwe'en cylinder 44 and sleeve 47.

Extension shaft '50 is cooperable with the keyhole slot 33 in keeper 30 and, for 'this purpose; has diametrically opposite radial pins 51 on its end. One quarter turn of shaft 50 by key 45 locks or unlocks drawer 40 relative to keeper 30.

Extension shaft 60 has a threaded end 61 cooperable with the threaded aperture 34. When drawer 40 is equipped with shaft 60, it is locked and unlocked by rotation of shaft 60 by key 45 to engage or disengage threaded section 61 relative to threaded hole 34.

By virtue of the threaded central hole 34 of, key-hole aperture 33, coin chute 10 can be interchangeably equipped with a coin drawer '40 equipped with either shaft 50 or shaft 60, so that only a single form of keeper plate is needed. To empty the coin chute, the service operator merely pulls a bag or sack .over'the end of chute 10 and unlocks and withdraws drawer 40.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
