7 Claims. 1

This invention relates to display cabinets for the storage, display and dispensing of merchandise, particularly nuts, and it has for its object to provide an improved cabinet of this class.

To this end I have provided a display cabinet of the class described whose contents are attractively displayed to View and contained with in two receptacles whereof one is disposed directly above the other, the lower receptacle being relatively large and occupying a fixed position within the cabinet and the upper receptacle being relatively small and continuously reciprocated back and forth on a rectilinear path above the lower receptacle, while the cabinet is in its normal condition, thereby to attract the attention of customers.

In the preferred form of this invention the cabinet comprises a housing or casing by which said two receptacles are normally inclosed, said housing being provided with a normally closed door or closure member that is adjustable into an open position to render the contents of the receptacles accessible and which, when opened, automatically stops the reciprocatory movements of the upper receptacle. Also, in the preferred form of the invention the upper receptacle is driven by an electric motor whose circuit includes a switch that is normally maintained closed by the door or closure member while the latter occupies its closed position, but which is automatically opened when the door or member is opened so that said upper receptacle is motionless While the door or closure member is open thereby avoiding interference with the removal of merchandise from the receptacles in making a delivery to a customer.

As an additional feature the preferred embodiment of the invention may provide for manual operation of the circuit of the motor while the door or closure member occupies its open position so that the upper receptacle can be shifted about under the control of the operator as sometimes may be necessary in making a delivery of merchandise.

Other features and objects of the invention will be hereinafter pointed out.

In the accompanying drawings Figure 1 is a front elevation of my improved cabinet, front panel of the base portion of the housing being broken away to expose the interior thereof.

Figure 2 is a section on line 2-2 of Fig. 1.

Figure 3 is a section on line 3-3 of Fig. 2.

Figure 4 is a sectional view like that of Fig. 3 but illustrating an alternative construction.

Figure 5 is a partial section on line 5-5 of Fig. 4. 5 Figure 6 is a sectional detail on line 66 of Fig. 2.

Figure 7 is a sectional detail on line 1-1 of Fig. 6.

The housing of the cabinet herein "illustrated 10 comprises a base portion It! made mostly from sheet metal and an upper portion, or superstructure, i i at the top of said base portion made up of panels I2 of glass or other suitable transparent sheet material held in place by a metallic framework that is an extension of the base portion Ill.

Within base portion I0, and at the top thereof, there is fixed a relatively large open receptacle in the form of a tray it which, as shown in Fig. 3, extends from one end wall of the housing to the opposite end wall and is interiorly divided by transverse partitions I l into a plurality of compartments to be filled with different kinds of merchandise. This tray l3 rests upon and is supported by longitudinal angle bars I5 fixed at their opposite ends to the end walls of the housing so that said tray is fixedly supported.

Directly above the fixed tray l3 there is provided a smaller open receptacle in the form of a tray it provided at its opposite ends with legs I! and 18, each of which is equipped with a pair of spaced apart trucks or rolls l9 which rest upon a pair of

longitudinal rails

23 and 2! which, as shown, may be horizontal flanges provided at the tops of the front and rear walls of fixed tray l3. As will be clear, this construction provides for back and forth movement of .upper tray I5 longitudinally on the rails 2i! and 2|.

The leg ll of tray It is provided at its lower end with a skirt extension 22 which is completely hidden from view within the base portion Iii of the housing, and whose lower marginal portion occupies a guide channel provided by the interior of a cross-bar 23 that is lJ shaped in cross-section, said cross-bar being rigidly fastened at its opposite ends to uprights 26 and 2-5 (Fig. 1) which, in turn, are rigidly connected with the base portion H] of the housing.

The skirt 22 is made with a vertical slot 2% that is occupied by a stud 2? projecting from an endless chain 23 which is supported in a horizontal position by two sprockets 28 and 3E. Sprocket 3B is rotatably supported by a stud shaft or pintle 3| projecting from a plate 32 that is adjustably fixed in position upon a cross-bar 33 by two screws 3% occupying slots formed in said plate, said screws engaging tapped holes formed in cross-bar 33. This provision for adjustment of sprocket 39 enables the chain 28 to be maintained tight at all times.

The sprocket 29 is loosely mounted upon a stud shaft 35 projecting from cross-bar 33 and is also compounded with another sprocket 3% connected by an endless chain 31" with a fourth sprocket 33 fast on a shaft 39. Shaft 39 is driven through reducing gearing by the armature shaft of an electric motor 60 fixed in position within base portion l0.

While motor 40 is operating it acts through the connections described to continuously actuate chain 28 in one direction, the stud 271 of chain 28 acting against the opposite sides of slot 28 to reciprocate the upper tray it whose motion is eifective to attract the attention of customers to the contents of the cabinet.

At the front side of the base portion if! the latter is made at its top with a longitudinal inturned flange ii whose inner edge occupies a position close to the path of the outer end of leg I! with the result that the means for actuating the upper tray i6 is completely hidden from view by said flange M and track 29, and this is a highly desirable feature.

One of the line wires of the electric circuit supplying current to motor 65 is extended by a cable 42 (Fig. 2) whose wires are connected with the terminals of a pushbutton switch it fixed in position upon the inside or the metal frame of the superstructure El alongside of a door or closure member 5-5 which normally occupies a position closing a doorway provided upon the rear side of the superstructure ii. While the door occupies its closed position it holds the pushbutton 44 of switch as in position to maintain said switch closed so that motor 66 operates continuously to reciprocate tray it so long as the door remains closed. When, however, the door 45 is swung upwardly toward its open position its pressure on pushbutton M is relieved thus permitting the usual spring contact 48 of the switch to shift the pushbutton into a position where the switch is opened thereby stopping the motor to and tray H6.

The door 45 is swung upwardly and when it reaches a horizontal position it may be slid edge- Wise into position upon brackets provided at the opposite ends of the superstructure upon the inner sides thereof. One of the brackets is shown at $6 in Fig. 2. These brackets serve to hold the door in its fully opened elevated position while delivery is being made from the cabinet and it will be clear that if the tray i is stopped in a position above a compartment of tray I 3 from which it is desired to make a delivery, then the switch 33 is accessible for manual operation to shift the tray out of the way.

Figs. 4 and 5 illustrate an alternative construction of fixed receptacle wherein the partitions 14 of Fig. 3 are omitted to adapt the tray l3 to receive within it a plurality of individually removable oblong bin units 46 disposed transversely with respect to the path of the reciprocating receptacle or tray l6, each of said bin units being adapted to hold and display a quantity of merchandise. Between adjoining bin units 46 are provided individually removable partition inserts 47 that are higher than the bins and preferably made from transparent glass or other suitable and rigid sheet material. As will be clear each bin unit may be loaded with a different kind of merchandise, such as nuts.

As shown in Figs. 2 and 4 the door 45 is equipped with two hooks 59 disposed upon the inner side thereof adjacent to the opposite ends thereof. These hooks are also disposed near the top of the door and each co-operates with a roll 50 mounted upon the proximate bracket 46 in position to provide a pivot on which the door may be swung up and down and on which the door is free to ride as it is moved horizontally while occupying its uppermost position. Rolls 58 also serve as stops to limit the outward movement of the door as it is removed from the bracket 46. Any other type of closure member may be substituted for the door 15 so long as it controls access to contents of the cabinet.
