Description:
BACKGROUND OF THE INVENTION
This invention relates to a replaceable currency or bill holder for a till tray.
The prior art tills are generally made of sheet metal with the individual bill or currency compartments and coin compartments thereof being made by welding various sheet metal sections therein to form the compartments. The associated bill holder for holding the currency is generally made of a relatively thick wire which is formed into the desired shape and dipped in plastic to coat the wire at the sections thereof which contact the bills. A spring placed in tension is used bias the bill holder to a position which compresses and retains the bills in the compartment.
One of the problems with this type of prior art till and bill holder is that it requires many welding operations to produce, and when in use, some of these weld spots break loose requiring replacement of the entire till; this is especially true when one of the weld spots breaks loose at a junction between the bill holder mounting means and the tray.
Accordingly, an object of this invention was to produce a low-cost till tray with a replaceable bill holder.
Another object was to design a tray and a bill holder which could be completed by injection molding of plastic material so as greatly reduce the initial manufacturing cost and facilitate the removal of broken bill holders without having to replace the entire till tray and bill holders therein.
SUMMARY OF THE INVENTION
This invention relates to a replaceable currency or bill holder for a till tray, and it includes a bracket means, for detachably securing the bill holder in a compartment of the tray, and a bill lever means. The lever means has a first end which is pivotally joined to the bracket means and a second end for contacting the bills in the compartment. The bracket means has a resilient means associated therewith, and the lever means has a camming means at a first end thereof to cooperate with the resilient means to resiliently urge the second end of the lever means into contact with the bills to resiliently compress and retain them in the compartment.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a plan view of a portion of a till tray having both bill and coin compartments therein, showing the bill holder means of this invention.
The bill holder means, designated generally as 10, is shown in a currency or bill compartment 12 of a till tray 14 which also has coin compartments 16 therein. When in use, the tray may be mounted in a drawer to fit into a cabinet (not shown) of a cash register or the like, to slide into and out thereof as is conventionally done, or the till tray 14 may be molded in the shape of a cash register drawer and used as the drawer itself.
The bill holder means 10 is comprised of a bracket means 18 and a bill lever means 20 as shown in FIGS. 1 and 2.
The bracket means 18 (FIGS. 1 and 2) has a leg portion 22 which slidably fits into a vertically-aligned recess 24 formed in the end wall 26 of the tray 14. The recess 24 is formed by two walls 28 and 30 which extend from the end wall 26, are aligned with each other, and are substantially parallel to the end wall 26. The walls 28 and 30 are tapered slightly to match the taper on leg portion 22. The lower end of the leg portion 22 has a projection 32 (FIG. 2) which fits into a complimentary notch 34 in the end wall 26 to detachably retain the bracket means 18 in the compartment 12. When it is desired to remove a broken bill holder means 10 from the compartment, for example, a screwdriver may be inserted into the notch 34 (FIG. 2) to push the projection 32 out of the notch to permit the bracket means 18 to be withdrawn vertically upward (as viewed in FIG. 2) to permit a new bill holder means 10 to be inserted in the compartment.
The bracket means 18 also has a pair of spaced parallel arms 36 and 38 extending at right angles to the leg portion 22 as shown in FIG. 1. A resilient means, shown as a leaf spring 40, is located between the arms 36 and 38 and also extends at a right angle from the leg portion 22. The top surfaces of the arms 36 and 38 and the leaf spring 40 all lie in the same plane (as viewed in FIG. 2) which plane lies below the top edge of the compartment 12 to permit the tray 14 to slide into a cabinet when used typically with a cash register or similar business machine. The free ends of the arms 36 and 38 have aligned apertures therein to receive the bill lever means 20.
The bill lever means 20, shown principally in FIGS. 1-3, includes a bill lever 42 which is slotted at a first end to provide a pair of arms 44 and 46 and a camming portion 48 as shown in FIG. 1. Each of the arms 44 and 46 has a rod 50 projecting outwardly therefrom, and these rods are axially aligned with each other and are rotatably received in the apertures in the arms 36 and 38 on the bracket means 18 to pivotally mount the bill lever means 20 thereon. To install the bill lever means 20, the arms 44 and 46 are bent slightly towards each other and the arms 36 and 38 on the bracket means 18 are moved apart, slightly, to enable the rods 50 to be inserted in the associated apertures in the bracket means 18, and all the arms are released thereafter to assume the positions shown.
The caming portion 48 of the bill lever means 20 cooperates with the leaf spring 40 of the bracket means 18 to enable the bill lever means 20 to be resiliently cammed to a first position in which the free end 52 of the bill lever 42 resiliently compresses a stack of currency or bills 54 in the compartment 12 as shown in FIG. 3, and to a second position in which the bill lever 42 is moved out of the compartment to permit access thereto, as shown in FIG. 4.
To accomplish the camming action of the bill lever means 20, the leaf spring 40 has a segment 56 which is positioned at an angle a as shown in FIG. 2. In the embodiment shown, which is drawn full size and designed to handle U.S.A. currency, a is 53° when the bracket means 18, including the leaf spring 40, is in the relaxed state. The included angle between the flat sides 58 and 60 of the camming portion 48, as shown in FIG. 3, is 70°. These flat sides are substantially perpendicular to radii which intersect at the longitudinal axis of the rods 50, and are joined by a suitable radius 62 (FIG. 4) to provide a continuous surface between the sides 58 and 60.
When the bill lever means 20 is in the position shown in FIG. 2, the leaf spring 40 tends to rotate the bill lever 42 in a clockwise direction (as viewed in FIG. 2) to resiliently urge the lower end 52 of the bill lever 42 into contact with the bottom 64 of the compartment 12. As the stack of bills 54 (FIG. 3) increases in height, the resilient force due to the cooperation between the leaf spring 40 and the camming portion 48 also increases. As the lever 42 is raised in a direction out of the compartment 12, a dead center position is reached when the radius of curvature 62 contacts the segment 56 of the leaf spring 40. When the bill lever 42 is pushed slightly in a counter clockwise direction (as viewed in FIG. 4) beyond the dead center position, the leaf spring 40 resiliently cams or rotates the bill lever 42 to the position shown, in which side 60 contacts the segment 56 of the leaf spring 40 permitting access to the compartment 12. The arms 44 and 46 have shoulders 47 (FIG. 1) which are perpendicular to the plane of lever 42 and which abut against the top of arms 36 and 38 on the bracket means 18 when the bill lever 42 is moved to the position shown in FIG. 4. The shoulders 47 cooperate with the arms 36 and 38 to dampen any oscillatory motion in the bill lever which may be present when it is cammed to the second position shown in FIG. 4. After inserting bills in or withdrawing bills from the compartment 12, the bill lever 42 is simply rotated in a clockwise direction (as viewed in FIG. 4) beyond the dead center position, and the leaf spring 40 will then resiliently rotate the bill lever 42 in a clockwise direction to the position shown in FIG. 3.
The bracket means 18 is made of a tough plastic material like acetal plastic, and the bill lever means 20 is made of a tough plastic material like nylon, which is manufactured by Dupont Corporation, although other comparable materials may be used. The bracket means 18 has reinforcing ribs like 66 and 68 on the arms 36 and 38, respectively, on the undersides thereof. The underside of the bill lever means 20 also has reinforcing ribs like 70, 72, 74 (FIG. 1) to provide stiffness to the bill lever 42 and to minimize the amount of plastic material used. The leaf spring 40 also has a reinforcing rib 76 on the underside thereof to add stiffness thereto. The bracket means 18, the bill lever means 20 and the till tray 14 may be formed by conventional plastic molding techniques such as compression molding, ram injection molding or screw injection molding. When molded, the bracket means 18 and bill lever means 20 may be mounted within the tray, as already described, without any addition work or machining. By this construction a low-cost tray and bill holder means is provided, which construction provides for over a 50 percent reduction in the cost of fabrication when compared to the till tray described in the prior art.
