To all whom-it may concern.-

Be it known that I, HENRY MQGK, a citizen .of the United States, residing at New York,

I county and State of New York,-have made 5;certain new and useful Improvements in an,

' Apparatus for Removing Cakes of Ice from Freezing-Cans, of which the following is a specification.

This invention relates toan improved apro paratus for removing cakes of ice from the cans in which theyare-artificially frozen in the'refrigeratiug machine, the removal being accomplished by utilizing the heat of exhaust .steam from the engine; and the invention 5 consists of an apparatus for removing cakes of-ice from the freezing cans, which comprises an inclined double-walled and steam-heated jacket,jopen at the ends and top, a hinged and tilting platform, located back of and in =5 line with the steam-heated jacket and means for-facilitating the tilting of the platform from the position in which it receives the cans into the jacket, so that the cake is loosened fromthe can by the heat to which it is subjected and thendelivered to a suitable storage rece'ptacle. a n v The invention consists further in certain details of" construction, which will be fully described hereinafter and finally pointed out 39 in th'cclaims.

In th accompanying drawings, Figure 1, represents a vertical longitudinal section on line 1 1, Fig. 3, of my improved apparatus for retnoving'cakes of ice from their freezing 5 cans showing the receiving platform in position for receiving a can and before being tilted into the steam-heated jacket. 1' Fig. 2,

is a vertical longitudinal section of the same on line 2 2, Fig. 3. Fig. 3, is a plan partly in.

c section, on line 3 3 Fig. 1, and Figs. 4 and 5 1 are respectively a vertical transverse section on line 4 4, Fig. 5, and a side-elevation, of the steam-heated jacket. I Similar letters of reference indicate corre- 5 sponding parts.

In the drawings my apparatus is shown with a double steam-heated jacket and two tilting platforms, whereby a double apparatus is obtained.

It is obvious that one apparatus or a mul- 'tiple of the same may be arranged side by I side, as l do'notdesire to confine myself to i the use of twoapparatus only.

The apparatus consists of a fixed and steamheatedjacket A which is supported in an inclined'position-on suitable timbersand con-' str'ucted of boiler iron riveted together. The cross-section of the jacket'A is made of U- 'shape'and double walled sides and bottom,

but open at the ends and top. To the interior space of the sides and bottom of the jacket A is supplied exhaust-steam from the engine orother suitable source of supply. The

steamsupply pipe at is connected with the upper part-of one oftheside-walls of the jacket, while the water of condensation and the noncondensed steam is conducted ofi through an outlet-pipe a located at the bottom of the jacket A. The lower ends of theside-walls of the jacket. are preferably out OK at the proper inclination, so'as to fit against the hinged door D which drops by gravity into closed position, said door being arranged above the inclined timbers or chute on. which the jacket A is supported. At or near the upper end of the jacket A is hinged a strong tilting platform of angular shape which is, provided at its sides with bracket-shaped guard-plates b. .The angular platform B rests on the floor of the h iilding in'which the freezing tank of the refrigerating machine is located, so that the cans with the frozen cakes of ice in the same can be readily transmitted by a traveling hoist or other suitable device to the platform. The upright portion of the platform B is provided at its end with a thickened port-ion or shoulder 1) against which the upper end of the can abutswhen placed on the platform and when it is tilted into the jacket A. The ends of the angular platform B swing along the rounded off portion (1 of the inclined top D; which in connection with the end-wall D hinged door D, side-walls D bottom of the jacket A, and the upright pory tion of the platform forms a closed heatingchamber the inner surface of the walls of which are lined with asbestus or other'suitable non-conductor of heat. I V 1.

The tilting platform B is hinged at the apex of its angle to the upper-bottom edge of the jacket. To the'pintle-of the hinge on which the platform B swings, is applied an' onto the platform, which is then in itsinitial.

position on the floor of the refrigerating building. The platform is then tilted with the-can intothe steam-heated jacket in such a man nenthat it rests on the inclined bottom of the jacket A. The edge of the can containing the cake rests then against the shoulder bof the outgoing end of the platform B and is thereby prevented from moving out of the jacket. The can is now entirely inclosed in-aclosed chamber in which a high temperature is sustaine'dbytheexhaust-steamconductedintothe double walls of the jacket. The heat in.the

. chamber produces the melting of the cake of ice in the can until it can liberate itself and v shoot forward by its own weight so as to open the hinged door D being then conducted over forth. P

from freezing cans, which consists of a star the inclined timbers to any suitable place of storage. The platform with the empty can is then returned by the rope or chain c and weight e to its initial position on the floor of the refrigerating building. Another can with a cake of ice is then placed on the platform, tilted with the same into the heating jacket, so that on the melting of the surface of the cake, itis delivered from the can and so on. By the use of two jackets side by side an alternating lowering and emptying of the cans can take place. V

The advantages of my improved invention are, first that cakes of ice can be removed from the cans ins shorter time than by the devices heretofore in use; secondly, that the construction is simple, easily handled and not liable to get out of order, and thirdly, that by the utilization of exhaust-steam, the thawing out of the cakes or blocks of ice is very economically accomplished.

Havingthus described my invention, I

claim as new and desire to secure by Letters Patent- L An apparatus for removing cakes of ice from freezing cans, consisting of a doublewalled heating jacket and a can-supporting platform adapted to be moved with the can into or out 2.
