I INVENTO/i UNITED STATES PATENT EDWARD E. GAINER, or NEW YORK, N. Y., AssIGNoR 'ro ZENAS U. DGDGE, orNEw,

YORK, N. Y.

ICE-MAKING APPARATUS.

To all whom it mag concern: I Be it known that I, EDWARD E. GAi-NER,

- a citizen of the United States, and resident the ice holding receptacles or freezing cans against displacement in the refrigerant tank.- These and other objectswill appear and be better understood from the following description taken in connection with the ac companying drawings, in which;

Figure 1 is a detail partlyin elevation and vertical section showing one embodi ment of my invent-ion. Fig.2 is a similar View on the line 22 of Fig. 1 looking in the direction of thearrow. Fig. 3 is a detail plan view of one of the freezing cans.

Referring to the drawings 5 indicates the header for the refrigerant fluid. This header, as usual, extends into the tank 6 and is connected to and forms the outlet of a suitable pump. The pump and its connection with the header 5 are well known in the art, and for that reason I do not deem it necessary to show this arrangement, since a statement to the effect that the pump draws the refrigerant 7 from the tank 6 and discharges the same through the header 5 will be sufiicient to enable those skilled in the art to carryout my invention.

The can 8 is interiorly provided with the freezing tubes 9, the upper ends of which are closed as shown at 10 and lie a trifle below the surface of thewater 11 when the same partially fills the can as shown in the drawings. The lower ends of the tubes 9 extend through the'bottom 12 of the can and are surrounded by bushings 13 which serve to protect the lower ends of the tubes and form a tight joint to prevent the entrance of the refrigerant fiuid into the can. The tubes 9 receive. stand-pipes 14 which communicate with the header 5 and extend to pointsadja'cent to the closed ends 10 of the tubes 9.

A common support for the header and can comprises a pair of metallic straps 14' Specification of Letters Patent.

straps embrace the header 5 and terminate in radial extensions 17 secured together in any preferred manner, such as by rivets 18. The radial extensions 17 of each strap are in vertical alinement and terminate in angularly disposed feet '19 and 20. The lower feet 19 bear upon the bottom 21 of the tank and the upper feet 20 bear upon the central portion of the bottom 12 of the can. By the provision of this form of support. the

header 5 will be held in spaced relation to the bottom 21, whereby -the tank 6 may be drained and thoroughly cleaned and also-the can 8 is supported above and in spaced relation to the header .5, whereby the. refrigerant fluid may more readily circulate through the tubes 10 and completely cover the bottom 12.

The stand-pipes 14 are approximately the same'in length as-the tubes 10, and since the latter are-but a trifle less than the length of the can it will be seen that these members will cooperate to prevent the can from toppling and center the same on the feet 20.

In use a quantity of water sufficient to cover the upper ends 10 of the tubes is placed in the can 8.- Suitable tackle is then connectedin openings .22 in the top portion of the can, after which the caniselevated and swung over the tank 6-and guided into alinement with the stand-pipes 14, and then lowered to the position shown in Figs. 1 and 2. During the operation of freezing the refrigerant '6 is circulated through 4 .the header 5 and stand-pipes 14 by the pump in the manner before described. After the water 11 has been frozen the can is removed from the tank and inverted. A suitable thawing agent may then be introduced into the tubes 10 and around the exterior .of the can, whereupon the cake of ice will fall therefrom. By constructing the tubes 9 in the manner shown the openings formed in the cake by the tubes will be bottomed. whereby the openings may be readily filled with distilled water.

Having thus described the invention what I claim as new and desire to secure by I .etters-Patent is:

1. In an'ice making apparatus, in combination, a refrigerant tank, a header arranged in the tank and spaced from the bottom thereof, a stand-pi )0 connected to the header, a can spaced ron1 the header, :1

55 and 15. The middle portions 16 of the freezing tube opening at one end through the'bottom of the can and closed at its oppof v site end and adapted to receivethe standpipe, and a common support for the header and can adaptedto hold the same in their relative positions. p

2. In an ice making apparatus, in com-' bination, a refrigerant tank, a header ar- 1 hold the can upon its support, and a support for the can arranged between said stand pipes. I

3. In an ice making apparatus, in combination, a refrigerant tank, a header arranged therein, a stand-pipe connected to the header, a can, a freezing tube opening at one end through .the bottom of the can and closed at its upper end, said tube being adapted to receive the stand-pipe and cooperating with the same to prevent displacement of the canwithrespect to'tlie header,

and a common support for thef'heade'r and can serving to hold the same in spaced relation toeach'other.

-4. In an ice making apparatus, in combination, a refrigerant tank,-a header arranged'threin, a stand-pipe connected to the header, a can, a freezing tube opening at one end through the bottom of the can -and closed at its'upper end, said tube corresponding in length approximately to the length of the stand-pipe and adapted to receiireth'e same and cooperating, therewith to prevent displacementof the can with respectto the header, and a support for the header bearing on the-bottom of the can and holding the same in space relation to the header.

In testimony whereof I aflix my signature in presence of, two witnesses.
