ICE-FREEZING TANK.

To all whom it may concern:

Be it known that I, JOHN H. LEWIS, a States, residing at R-hinelander, in the county'of Oneida and State of Wisconsin, have invented a new and useful Ice-Freezing Tank, of which the following is a specification.

This invention relates to ice freezing 4 tanks.

The object of the invention is. to provide an apparatus of this character that shall be adapted for freezing water into lumps of ice of any desired shape without the employ ment of an artificial refrigerant, and in whiclrthe removal of the cakes maybe accomphshedin already and rapid manner.

With the above and other objects in ,view;

as will appear as the nature of the invention is better undertsood, the same, consists, generally stated, in a tank divided into oompartments of a size that will determine that of the cakes of ice. This tank is a knock down structure and comprises bottom, side. The bottom is pqreferablyand end walls. of metal and the side and endwa of wood covered with metal, while the compartments and the partitions forming the compartments will preferably be made of metal, per

se. The side, end and bottom walls are held' detachably assembled, and in order to prevent the escape of water, a suitable packing preferably of rubberwill be interposedbetween the meeting edges of the parts.

As a matter of further improvement, there is provided means for supplying a current of heated air or the like beneath the bottom and between the side and end walls, whereby to cause the ice to melt these points and thusthe partitions.

Further and more specific details of con struction will hereinafter more fully appear. Inthe accompanying drawin s forming a part of this spccificatioman like lcliaracters of reference indicate corbecome detached from these parts and from responding parts :-Figure 1 is a view in perspective of an ice freezing tank 0onstructd in accordance with the present in vention.

Fig. 2 iis an inverted plan view. Fig. 3 is a transverse sectional View taken on the line 3-3, Fig. 2. Fig. et is a perspective detail view of a portion of the apparatus.

a The tank, as above stated, comprises side walls 1 and 2, end walls-3 and 4, and a bottom wall 5. The side and end wallsare prefcrably constructed of longitudinal and varin which series of compart'ment-s 9 in each of the four walls, one being shown in .Fig. 3 into which the heating. medium is introduced for the purpose ofloosening the ice.

Arranged within the tank is a series of partitions'lO defining com artments in which the'water is placed. and t ese partitions are held in verticaL'position'by keepers or cleats 11 secured totheilpper "edges of the side walls." ha buoin 5 is constructed of a 'sheet12ofmetal, and 'is secured to a gridded frame, comprising;longitudinal and trans veise beams Bandit. I

Secured at each corner of the side walls is a" )ost"l5 .and'these sts extend above and below theuppeij'and liiiver. edges of the tank,

and are engaged by the turn buckles 16 by which the parts-are firmly clamped together transversely. In order to exert longitudinal draft upon the'end walls two cleats 17 are employed, the upper end of each of which.

is provided with a flange 18 to engage with the upper edge of the end walls, and the lower end of each ofwhich is arran ed to receive a longitudinal bar 19 which is t readed for the reception of a lever 20, by which pressure may be a plied to the end walls.

In order to render the tank water-tight, there is a packing ,of rubber or other suitable material 2l-inter osed between the meeting portions of tlie'sidb and end walls.

The means for effecting the release of the frozen product comprises a false bottom 22 tical beams v6 and 7, andthese are inclosed- Specification of Letters Patent. ,Paterited ltIar. 14;, 1911. Application filed January 3, 1910. .Serial No. 585,959.

which is provided with a pipe 23 to be connected with a blow torch or a steam pipe.

' This false bottom is, as shown in Fig. 2, dis- )osed over the longitudinal and transverse earns 13 and 14 of the bottom, and upon the heating medium being supplied to the pipe 23, the same will circulate around the bottom and between the sheathing of the side and end walls, passages 24 being provided to secure the desired circulation. 'lhe heating medium escapes through openin s 25 formed in the side and end walls, as cliaarly shown in Fig. 1. The heat can also be applied by placing a blow torch or the like to the sides and bottom of the tanld and thus do away with the space in the walls.

In the operation of the tank after the arts have been properly assembled, it is filled with water and placed outof doors and when all of the 'water'is frozen, the

, lishing communication between the interior of the posts for binding thesi ewalls against the side edges of the end walls, partitions with any part of the tank, one of the ends. I

is removed and the ice taken out.

I claim 1. A freezing tank comprising a false bottom, having an inlet, a gridded frame bearing onthe false bottom, an upper bottom secured to said frame, there bein openings within theframe, hollow side wa s lapping the sides of the frame and bearing onthe false bottom, there bein passages for estabof the frame andthe interiors of the side walls, hollow end walls bearing upon the false bottom and against thev ends of the frame, the interiors of said end walls communicating with the interiorofthe frame, corner posts secured to the ends of the side walls and extending above and below the frame, means engaging the] rojecting ends interposed between the side walls, and keep-,n
