MANNING, OF RUTLAND, VERIIIONT, ASSIGNOR, BY MESNE ASSIGNMENTS, TO MANNING MANUFACTURING COMFANY (INCORPORATED), OF RUTLAND, VERMONT, A CORPORATION OF VERMONT, AND BEOOKS'CABINET COMPANY, INC, OF NORFOLK, VIRGINIA, A CORPORATION OF VIRGINIA ICEQREAM CABINET Application filed September 20, 1927. Serial No. 220,709.

This invention relates to a new and improved ice cream cabinet.

One of the objects of the invention is to provide a cabinet having containers for holding the mixture of ice and brine or other refrigcrating means, which shall be so designed as to eliminate dead air spaces which are difficult to cool and to maintain in a cooled condition.

Another object of this invention is to provide asimple and eilicient construction for the ice containers whereby the same can be readily manipulated whenever it is necessary to insert them into or to remove them from the cabinet.

Another object of this invention is to provide means in thecabinet whereby the respective ice containers will be forced towards each other so as to snugly abut the can of ice cream.

Another object of this invention is to pro vide means for spacing the bottoms of the ice containers from the bottom of the can of ice cream and also from the bottom of the cabinet so as to provide a cold pocket.

Another object of this invention is to pro vide the respective ice containers with flanges which shall cooperate with a corresponding bead formed in the ice cream can.

Another object of my invention is to provide a construction whereby the ice cream can is completely surrounded by the ice and brine so that all parts of the ice cream are main tained at the proper temperature and con 86 sistence.

Other objects of the invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above statement of the objects of this invention is intended merely to generally explain the same and not to limit it in any manner.

Fig. 1 is a central sectional view partially in elevation.

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

Fig. 3 is a perspective view of one of the ice container elements.

Fig. 4 is a detail sectional view on the line 4 of Fig. 2.

The cabinet 0 may be of any suitable construction and the size shown herein'is sufiic-ient to provide for two cans of ice cream. However, the improved construction may be adapted to a cabinet of any desired size.

As shown in Fig. 2 the interior of the cabinet is preferably rectangular in shape, in order to enable the ice containers, which have a general rectangular contour, to fit snugly against each other.

7 As shown in Fig. 8, each ice container '1 has a substantially rectangular shape, one face thereof being provided with a vertical concave or recessed portion 2. The ice container 1 is made of any suitable metal and it is provided upon the inner side of the concave wall thereof with a hand hold 3 by means of which it can be readily manipulated. The

top of" the container 1 is provided with perforated metal strainers 4:, adjacent the concave wall thereof. These strainers make it possible to easily discharge the brine, when it is desired to refill the-containers. The covers 15 of the cabinet have beveled edges, which makes themair tight.

As shown in Fig. 4 the bottom of the cabinet C is provided with spacing members 5 provided with shoulders 6 upon which the bottoms of the ice containers 1 are adapted to rest. These spacing members 5 are also provided with inclined or wedge-shaped vertical extensions 7 They are connected to the bottom of the cabinet C by screws or other fastening members 8. g

Hencewhen a pair of cooperating ice containers or trays 1 are pushed into the cabinet C, they are forced towards each other by the inclined projections 7 so that when they rest upon the respective shoulders 6, their inner edges are very close to each other or may even touch each other as illustrated in Fig. 2

for example, and their respective concave walls 2 tightly abut the corresponding cylindrical wall of the ice cream can 9..

As shown in Fig. 1 the bottom of the ice cream can 9 extends below the bottoms of the ice containers 1. s

Thebottom of the ice cream can 9 may rest upon. or remain above the bottom of the cabinet. 1

As shown in Fig. 3 the concave wall 2 of the ice. container 1 is provided with a shoulder 11 which is produced b offsetting the upper part of the concave wall2 V b The 'ce cream can 9 is provided at the uppergart thereof with a pro ecting bead 12 whic is adapted to rest u on the shoulders 11 of the associated pair ice containers 1. Hencethe top of each ice cream can 9 is spaced from the tops of the associated ice containers 1, so that the cover 14 of each ice cream can 9.can be readily removed and applied. The to of the cabinet is provided withcovers 15 .0 any suitable type. 15 Assam commodates four ice containers 1 and two ne!!! of ice cream,.the said four ice containers substantially fill up the entire interior of therabinct and theiradjacent edges preferablyabut each other tightly while their concave walls snugly contact with the respectiveice cream cans so that while the ice brine can be handled much more conthan. when it is packed into a cabinet without the use of trays, the use of such'trays does not, lower the refrigerating eificiency because there are no air spaces between the cans of ice cream and their associated ioecontainersan .Of course it is who understood that this invention is not limited to absolutely perfect contactbetwcen the respective ice containers, orbctween the respective ice containers and thci cansof ice cream, because such tight contact is impossible in commercial devices of I-Iowever, if is any layer of air between 0. can of ice cream and the correspondice containers, this layer of air is very thin so that it can be cooled very rapidly toY-descend into the pocket of cold air formed by the spacing members 5.

while the use of the trays facilitates the operation of putting ice into the cabinets, or removing the melted ice therefrom, the

device has substantially the same efliciency as if were packed tightly around the respective cans of ice cream without the use of any trays.

The eficiency of the refrigerating effect is increased by the fact that the beads12 of the vcam-r9 rest upon the shoulders 11 of the ice containers 1 so asto form an upper seal between the cans ii and the concave walls 2. Likewise, this bead conducts the heat directly "fremlthe cold metal walls of the ice conto the metal wall of the ice cream can so'tltat a superior cooling effect is produced. These beads 12 can be made as large as desired,-to secure said direct conduction. While I have illustrated my invention as applied to an ice cream cabinet, it is obvious that the'invention'is applicable to other uses.

I have illustrated and prefer to use containers each having a general rectanguing for example that a cabinet ac lar contour so as to fill up the interior rectangular space of the cabinet C as much as possible, I do not wish to limit my invention to this detail because a considerable increase in refrigeratin efliciency will be secured by utilizing the eatures above specified, even if the respective containers do not have the general contour previously described and illustrated for example, in Fig. 3.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions could be made without departing from the spirit of my invention.

I claim:

1. In combination, refrigerating means having a Wall made of conductive material and having a substantially horizontal shoulder intermediate the top and bottom thereof, and a can having a bead adapted to rest upon the said shoulder.

2. In combination, a cabinet, refrigerant containers located in the said cabinet and having adjacent walls provided with vertical recesses whose inner walls are adapted to be closely associated with a can containing material to be cooled and means associated with said cabinet and adapted to force said refrigerant containers towards the said can.

3. In combination, a cabinet, refrigerant containers located in the said cabinet and having adjacent walls provided with vertical recesses whose inner walls are adapted to be closely associated with a can containing material to be cooled and means associated with said cabinet and adapted to force said refrigerant containers towards the said can, said means comprising wedge-shaped members located at the bottom of the said cabinet.

4. In combination, a cabinet having upwardly projecting spacing members at the bottom portion thereof, said spacing members being provided with shoulders, refrigerant containers located in said cabinet and resting on said shoulders, said spacing members also having upwardly directed wedge-shaped portions extending above said shoulders, said Wedge-shaped portions being adapted to force said refrigerant containers towards each other, the adjacent walls of said refrigerant containers having vertical recesses, a can containing material to be cooled, said can being located within and having its outer walls close to the walls of said recesses, said refrigerant containers having shoulders near their tops, said can having a bead adapted to rest upon said shoulders.

In testimony whereof I aflix my signature.

I ROY A. MANNING.
