To all who/mit 'mai/concerm Be it known that I, ROBERT J. BERRYMAN, a citizen of the United States, residing at napolis, in the county of Anne Arundel and State of Maryland,'have invented cer? tain new and useful Improvements in Methods or Processes for the Manufacture of Artificial Ice, of which the following is a specification.

My invention relates to an improved method or`process` for` the rmanufacture of artificial ice, and the primary object ofthis invention is to provlde means for forming ice in cans and removing it -fromthe cans without theinecessity of removing the cans" from the tank. I

Another object is to provide an Improved method of manufacturing ice in cans whereby it is possible to removeand dispose of' all impurities in the water during the proc-y ess Vof freezing thereby obvia'ting the necessity .of first .distilling and iiltering the water preparatory to the manufacture of transparent .can ice.

With the foregoing objects and others 1n view, my invention consists 4in freezing the .water in cans so located in la tank that space is left .on all sides thereof, and- `after the.

completion of the freezing process introducing-a thawing medium in the spaceslaround the cans, whereby the .ice formed is thawed from the cans and it is renderedremovable Klo.

without moving the cans.

My invention further consists in the methodl of manufacturing ice which consists in freezing it in cans `from one or both sides toa predetermined depth, and .subsequently draining the .water left remaining '1n the cans.

My invention further consistsin the meth-l od of manufacturing ice which consists in freezing it in cans from one or both sides to a predetermined depth, and subsequently draining thev water left remaining in the Cans, and a i-tating ewater i-n the cans during the reezing process. Myfnvention still further conslsts in cer tain procedure which will"y be I hereinafter out the claims.` n y v In the acoompanyingfdrawin 'sz-'Figure 1.-is a longitudinal, vertical section th .ough the machine. Fig. '2 is'a top planl vie ywith the covers removed. Fig?) is-a; modification.

The tank A is preferably of steel, ali though it may be made of any suitable ma- .terial and it is supported in a suitable framework B', between which andthe tank' there is a heavy insulation :1, of any suitable material, Inside of the tank A there are lo ca ted'as many-cans C, C, as the capacity of the tank will admit, according to the size of the plant. These cans C, C, are preferably made of galvanized iron asvis customary,

and they are -vmade in the desired dimensions. For example, the larger or inside across the bottom of the tank A, and they .are so arranged within the tank that space is left entirely around each can. In the coils of pipes.l 3, 3, are placed for conducting spaces intervening between everyV two cans,

the refrigerific mixture through the machine, this mixture vbeing introduced through thevalve 4, and after it has passed through the coils, it is returned through valve 5' in the return pipes 6. In lieu of the coils plate v 20 might be employed as shown in Fig. 3,

for the ammonia' gas or other -pcold ,liquid used in the freezing process. As the freezing mixture extends alongsidev the cans, the water in the cans freezes from opposite sides,

toward ythe center, so that two cakes are i formed in all but the outside cans, in which latter only one. is formed, as theffreezing. mixture only extends along one side of them. If the freezing process continuessuiiicientlylong, the two cakes of ice thus formed, will come together at the center, and form a single block of ice, and if desired, this may be 'done in every instance. For obvious reasons, which I will r'nenton,.however,'1 prefer that these cakes should not freeze togethenand my reason for this islthat it is my purpose in my method of manufacturing ice n ot to boil, anddstil the water used in the manufacture of the ice in order'to .remove the impurities, but on vthe contrary -to use raw or ordinary river or spring water,

and by agit'ating the water in the cans `while freezing it, VI conveniently accomplish this. l

by the introduction of compressed air or ozone through pipes 8, 8,'11`her'ating it i through /fperforations vor openings the pipes so that it rises through the water, and A by not freezing the cores of the' cakes or blocls of ice, that the ice formed is Aperfectly transparent, and free from foreign particles and all impurities, and that any to stop vthe freezing process when the cakes of ice freeze to a point within about two inchesor so of each other, whereupon the hollow plugs 9, 9, are removed' from the 'cans and the water remaining in the cans between the cakes whichcatches and holds any impurities there may be in suspension,

I is then allowed to drain od.' Should'the the bottom of the cans.

plugs become frozen, they are easily removed by introducing warm water or other medium into them previous to pulling them out. In the intermediate cans these plugs are located in the vcenter of the cans, whereas in the outer cans they are near the outer edge as indicated in Fig. 2. These hollow plugs taper gradually from the point where they enter the orifices in the bottoms of the cans upwardly, and thus when thawed loose they have served as a mold to form an opening through the ice, formed at the bottom of the can for the discharge of the impure water at the core out through the orifice at In this way a perfectlyv clearand transparentblock of ic'e is formed, which is absolutely free from im A purities.

To facilitate the removal of the. cakes or blocks of ice from the cans, eye-bolts or hooks or other devices 10, 10, may be frozen therein asa `means for attaching the blocks to an overhead crane for removing them from the cans. Previous to removing the y ice from the cans, its surfaces are thawed i out difficulty.

from the cans by introducing water or other liquid above freezing temperature from the lpipes 11 through valve 12, which water or liquid surrounds every can filling the spaces "left between them, and it is permitted to :iear that the advantageous features of ooth can and plate ice are preserved while at the same time s better product is ob tained, and it is handled with greater convenience and economy. Heretoforein can ice, itll'has been 'the usuel practice to remove the cans and dip them into a thawing vat in order to loosenand liberate the ice, but this labor and expense are avoided by removing the ice from the can without disl turbing the can, lin this invention, and furthermore by the process of this invention it is unnecessary to distil and filter the water used in the manufacture of the ice.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my in vention, and hence I do not wish to limit myself to the exact construction herein set fort-h, but Y Having fully described my invention, what I claim as new and desire to secure by Letters Patent is z- 1. The herein-described process of manufacturing and harvesting ice, which consists in si'irrounding the receptacle in which the ice is formed by a freezing fluid'which fluid is reduced in temperature for freezing the contents of the receptacle, and subsequently heated for thawing the ice from the receptacle.

2. The herein-described method. of manu facturing ice which consists in submerging cans exposed on all surfaces and containing a measured or predetermined quantity of water to be frozen into two plates of ice, in a iiuid medium, then conducting 'a rcfrigerating medium through said fluid medium whereby to reduce its temperature and cause the freezing of the measured quantity of water, and subsequently substituting for said fiuid, a thawing medium, whereby to heat the entire volume of thawing medium uniformly whereby to thaw the ice loose on all surfaces of the cans in which it is formed.

3. The herein described methodv of man-ufacturing ice which consists in freezing water simultaneously from the several walls and bottom of the cans, molding an outletthrougli the ice formed on the bottom of the can in alinement with an orifice in the bottom. of said cam-and finally thawing the mold loose from .the ice, and drainingQthe water contained in the center of the ice out through the hole in the ice and the bottom of the can. l

el.. The herein-described method of manufacturing ice which.- consists in surrounding a measured quantity of water inclosed in a suitable receptacle with a freezing fluid whereby said receptacle is exposed on all surfaces to the influence of the fluid, then conducting` refrigerant through said Huid whereby to cause it to freeze the measured quantity of water, and finally conductinga thawing medium through the fluid whereby to raise the temperature of the latter and cause it to thaw the 4ice loose.

5. The herein-described method of manullt) rfacturing artificial ice, which consists into quickly and simultaneously raise the temperature of the uid adjacent to -the outer surfaces of the ice -to cause-its release from the receptacle in which the ice is formed.

ln testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.V
