Dec. 10, 1929. w. R. WILLAUER APPARATUS FOR DISPENSING ICE CREAM Fild March 26, 1928 Patented Dec. 10, 1929 PATENT OFFICE WILLIAM R. WILLA'UER, OF SPARTANBURG, SOUTH CAROLINA APPARATUS FUR DISPENSING ICE CREAM Application filed March 26, 1928.

The object of this invention is to provide a simple method and means for reducing the expense and increasing the sanitariness of handling ice-cream in its transmission from the manufacturer through the retail dealer to the retail customer, as more fully hereinafter set forth.

A special object of this invention is to improve the devices for elevating the ice-cream 1o container from time to time as the level of the ice-cream therein descends, as more fully hereinafter set forth.

In the drawing Fig. 1 is a view partly in side elevation an 1 115. partly in vertical section of a portion of a refrigerator commonly used in retail establishments for ice-cream;

Fig. 2 is a horizontal sectional view thereof on the line 2-2 of Fig. 1;

Figs. 3 and -lare views of details herein after described.

In my copendin application, Serial No. 26%,770, filed even date herewith, I have shown a screw mechanism for raising and lowering the carton in the refrigerator can, whereas in the present application I illustrate and claim a counter-balanced form of apparatus whereby the carton may be more readily stepped up or elevated from time to time as tile ice-cream is removed from the carton.

In the drawing, designates the usual metal can built in the refrigerator and 11 indicates a paper carton set down in said ca and adapted to be raised from time to time as the level of the ice-cream therein lowers. As the carton is thus raised from time to time, the top edge of the carton (which carton is desirably made of paper or paper-board) is to be torn off and discarded. For raising the carton, I employ a pair of cables 12 affixed to the lower end of the bottom-plate 13 on which the ice-cream carton 11 rests and extending upwardly over pulleys 14, the free ends of these cables hanging down on the outside of the pulleys and being connected to counter-balancing weights 15. These weights 15 are not sufliciently heavy to raise a. carton completely filled with ice-cream, but they are of suflicient weight to raise a partly- Saris No. 264,771.

empty carton. For instance, it is desirable to elevate the carton after say a gallon of icecream has been removed therefrom, and at this point the Weights 15 are sur'licient of th mselves to raise the ice-cream carton.

To govern this automatic raising of the carton by means of the wei hts, I employ very simple devices. I aliiX to the container 10 a vertical plate 16, one of whose edges is provided with semi-circular notches 17 in which pins 18, carried by the bottom-plate 13, are adapted to engage. A companion plate 19 is arranged edge-to-edge with respect to the plate 16 and is connected thereto by a pair of parallel links 20 inclining upwardly from their pivotal connection to the stationary plate 16. A coil spring 21 connects the two

plates

16 and 19 and tends to draw them together, so that the companion notches in the plate 19 will automatically engage the pins 18. To elevate the ice-cream can or carton, it is necessary simply to depress the removable plate 19 against the action of its spring 21, whereupon the upwardly-inclined links 20 will throw these plates 19 out of engagement with the pins 18 and thus permit the weights 15 to automatically elevate the ice-cream carton to the height desired, whereupon the plates 19 are rel ased to permit the springs 21 to draw said plates 19 back into engagement with the pins 18 and thus lock them against further ascent.

It will be understood that the ice-cream carton 10 is desirably made of paper and is so constructed that it may be ripped or torn off or otherwise removed at the top as the ice-cream is used up by the retailer, to thus bring the surface of the ice-cream in the carton to a height where it will be convenient for the retailers clerk to remove the same. Any one of the three ways of weakening the carton illustrated in my copen-ding application or any other manner of reducing the carton in height as the ice-cream is used may be employed.

I have shown two sets of the plates 1619 arranged at diametrically opposite points and equidistant from the weight-pulleys 14, but it will be understood that more or less sets of these releasing-and-locking devices pression of one of the may be employed Without departing from the spirit of my invention.

The scope of the invention is not to be limited by the specific embodiment shown in the drawing, but only by the appended claims.

What I claim as new is:

1. In an apparatus of the class set forth, a refrigerator receptacle, an ice-cream can adapted to be set down in saidreceptacle, a support for the ice-cream can, weight-operated means for elevating said support automatically, the Weight of the Weights being insufiicient to thus elevate the ice-cream can until a portion of the contents has been re moved, and manually-operable means for controlling the lifting of the ice-cream can by means of said Weights.

2. In an apparatus of the class set forth, a refrigerator receptacle, an ice-cream can adapted to be set down in said receptacle, a support for the ice-crealli can, Weightpperated means for elevating said support automatically, the Weight of the Weights being insufiicient to thus elevate the ice-cream can until a portion of the contents has been removed, and manually-operable means for controlling the lifting of the ice-cream can by means of said weights, said means embodying companion notched plates engaging pins on the cam-support and devices Where by these plates may be manually separated.

3. In an apparatus of the class set forth, a refrigerator receptacle, an ice-cream can adapted to be set down in said receptacle, a

5 support for the ice-cream can, Weight-operated means for elevating said support automatically, the Weight of the Weights being insufiicient to thus elevate the ice-cream can until a portion of the contents has been removed, and manually-operable means for controlling the lifting of the ice-cream can by means of said Weights, said means embodying a pair of companion notched plates with notches to engage pins on the can-support, a spring for normally drawing each pair of plates together to thus engage the intermediate pins, and means whereby deplates ill. separate them sufiiciently to permit the pins on the support to rise in a path between the plates.

In testimony whereof I hereunto afiix my signature.

YVILLIAM R, WILLAUER.
