application aum: s, 1944, serial No. 548,69#

The dispensing of frozen foods creates quite a problem. They must be constantly maintained at an exceedingly low temperature well below the freezing point, and if placed in the usual ice boxes. y `or refrigerator chests' it is necessary for the 'ment of packages.

Another object of the invention is to provide a frozen food dispenser which will deliver the desired package within convenient reach of the customer; which will immediately place a new package in the position occupied by the removed package, and which will employ the successive packages to seal the delivery opening while the latter is open so that external air cannot enter and cold air cannot escape from the storage chamber.

Other objects and advantagesreside in the detail construction of the invention, which is designed for simplicity, economy, and eillciency.

'I'hese will become more apparent from the following description.

In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description. y

In the drawing: 1

Fig. 1 is a fragmentary view illustrating a portion of the front of a food dispenser in which the invention is embodied;

Fig. 2 is a similar inside face view of the dispensing doors of the cabinet of Fig. l;

Fig. 3 is an enlarged vertical section taken on the line 3 3, Fig. 1, illustrating one of the dispensing doors opened; i

Fig. 4 is a horizontal sectional view, looking downwardly, taken on the line I-I, Fig. 3;

Fig. 5 is a detail view of the package pushing device taken on the line 5`-5, Fig. 3.

The improved dispenser employs an air-tight cabinet having suitable walls III containing any suitable heat insulation 3|. The front of the cabinet is provided with an open framework Il 7 Claims. (Cl. S12-38) 2 frame I3 may be formed of wood covered with metal. An insulated door II closes each of the -door openings, said insulated doors being mounted at their bottom edges on"spring hinges I2 which constantly urge -the doors to closed position. The heat insulation 3| may be placed between the walls of the framework outlining the openings, as shown in Flg.3, if desired.

Each of the door openings is preferably formed with a wedge shaped door receiving bevel 32 at the front for receiving and sealing to a wedge shaped back I4 on the door. Each door opening in theI framework I3, adjacent the inside of the cabinet. is bordered by means of a flexible sealing gasket I5 projecting inwardly into the door opening at the sides, top and bottom thereof. The gasket I5 is formed of any suitable flexible elastic material such as rubber, and is secured to the inner face of the door frame by means of an attachment strip I6 or in any other desired manner.

A pair of slide rods I1,-extend horizontally inward from the bottom of each door opening to the back wall III of the cabinet. These slide rods are for supporting a series of frozen food packages I8 behind each door opening. The packages are forced forwardly along the slide rods by v means of an L-shaped pusher plate I9, the bottom of which is extended horizontally rearward to rest upon the slide rods I'l. The horizontal portion of the pusher plate is attached to sliding sleeves 20 through which the rods I1 pass. Each sleeve 20 carries a friction spring 2| which bears against the slide rods to resist movement of the pusher plate I9.

The pusher plate is moved by means of two notched bars 22, there being one bar on each side of each series of packages I8. The bars terminate at'their inner extremities in an open frame 23 surrounding the rods I1. They terminate at their forward extremities on hinge pins 24 which are imbedded in the door backs I4 so that each time a door is swung outwardly and downwardly the rods 22 will be pulled forwardly one package Width. The lower edges of the rods 22 are formed with ratchet-like notches 25 which engage the extremities of -a cross rod 26 carried by the slide plate I9. The spacing of the notches along the bars 22 corresponds to the thickness of the pack- 5 ages Il.

outlining a plurality of door openings. The 5 It can be seen that when a door I4 is opened the series of packages back of the door will be moved forwardly one package width. Thisy allows the foremost package to fall forwardly, as indicated on the lower door of Fig. 3, and pushes the next succeeding package into the embrace of the sealing gasket I5. This places the rst package within easy reach of the customer, and causes the second package to act as a sealing member to completely seal the cabinet while the door is open. g

As the door is swung closed the ratchet-like notches 25 will slide over the extremities of the cross rod 26 so that the latter will be engaged by the next forward notch of the series. The springsr 2| prevent the slider from moving rearwardly with the rods 22.

It will be noted that the foremost package does not come directly into contact with the closed door. This allows an air space about the package which will become chilled from the cold interior of the cabinet to maintain cold air around the said foremost package. i

Should it be desired to replace the packages I8, the door I is forced further downwardly than its normal open position. This brings a stop pin 21 against the bottom of each bar 22 to tilt the latter upwardly at the rear so as to completely release the cross bar 26. With the door in this position new packages can be forced through the gasket opening to push the pusher plate I9 rearwardly along the slide rods. It will be noted that as the new packages are placed in the cabinet, the latter is constantly sealed by the gasket I5.

Additional sealing gaskets, such as indicated at 28, can be inset in peripheral slots in the framework about the door opening, as shown in Fig. 3 to provide a more effective seal against the packages. The bars 22 and the rods 21 pass through snug openings in the flexible gasket I5 so that the latter will form a seal thereabout. Each door is preferably provided with a descriptive label 29, designating the contents behind that particular door.

The cabinet is preferably of the type having means for circulating a flow of cold dry air throughout its interior with a chilling coil arranged externally of the food compartment for chilling and dehydrating the air so as to prevent the formation of frost on the rods and mechanism.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, withinthe scope of the appended claims, without departing from the spirit of the invention.
