To all whom 'it vBeit known that I, Ammin H. BUGKLEY,

v"a citizen of the United States, and residing atCincinnati, Hamilton county, State of Ohio, have inventedcertain new and useful Im rovements to be Used in Connection wit the Manufacture of Ice; and I do declare the following to be a clear, full, and exactdescription thereof, attention being called' to the accompanying drawin ,.with the reference characters marked t ereon, which forms also a art of this specification.

This invention re ates to improvements to be used in connection with the manufacture of artificial ice.

In the most usual method of manufacture eratin agent.' After the water in them has been ozen, the icc in form of a block is removed from the can. In another form, water is caused to lie against a'cooled surface by which it is frozen, the resulting ice being in form of a large sheet, also called late-ice. These ieces of' ice are quite ea the .Nice b ocks produced in cans weig g froml 300 to 600l pounds, while plate-ice weighs twice and more times as much. Reduction of these large pieces becomes necessary to facilitate their handlin when distributed to the trade. For suc purpose these larger pieces are subdivided in two or more smaller parts in which form the ice ma be more readily handled, moved and loade` upon delivery wagons etc. Va-` rlous devices are used for such purpose tov cut up and otherwise to subdivide these blocks. Heat is used in connection ywith some of these devices, the ice being thawed apart. This manipulation requires time and is accompanied with loss of ice. I have discovered that withoutyieldin the advantage of freezing larger bodies o water at once, blocksof smaller sizes may nevertheless be obtained at the same time' by supporting in a certain manner a medium of certain material in the water which prevents this latter from freezing into a solid one piece. block.

In the following'specification and particularly pointed `out in the claims at the end manufacturing tion as shown in Fig. 2, whereafter,

construction, which latteris.

also illustrated in the accompanying drawlngin wh1ch:-

igure 1,-shows in perspective view one of the customary freezin -cans used in ice plants to old the water to be frozen. F1 2, is a side-view of thiscan s'howing how t e same is tilted to an inclined position to release the ice-block contained therein. Fi 3, illustrates inv perspective view an. imp ement used in connection with my invention. Figs. 4 and 5, are intermediatev portions of enlarged cross sections of a can as shown in Fig. 1, the invention being shown in modified form in each figure. Fig. 6, illustrates another form of my invention in an enlarged cross-section.

Where block-ice is manufactured, boxshaped cans are used, which are open at one of their ends to admit the water and to permit removal of the ice after the water is frozen. The walls of these cans toward the other end opposite the open end draw in somewhat, givin the can a ta er to cause the ice to leave 4t e same more eely. This closed end which constitutes the bottom of the can is usually of rectangular shape as shown at8 in the, drawing.

9 are the wider sides and 10.are the nari nipulated thereafter to obtain the ice-blocktherefrom. This manipulation consists 0f depositing the can upon a device called icedump, and of tilting it thereby to a osieat having been applied in a suitable manner,

the ice is quickly released and slides out of the can. The manufacture of late-ice differs at this point somewhat t e ice which has .formed being lifted out of the Water which remains unfrozen, means like rods with eyes, permitting connection of hoisting apparatus to be made, havlng been frozen 1n with the ice. In either case the blocks or plates roduced by either of these methods are too arge to be handled conveniently and they are at once sub-divided as before alluded to, by any of the various means-provided for the purpose.

By reezing in with the ice, asultable medium which' prevents the water from freezing into one continuous solid block, the

aforesald sub-,division may be alreadyl ob- 'comes necessary after the ice has tained while the ice is forming so that no further manipulation for this p ose beremoved from the container in which it has p been formed.

stead the Atenacity ofthe block at the paring of the water My invention consists of sup orting with-y in the water to 'be frozen an in a certain manner and bycertain means, one or more dividing partitions or diaphragme 12 which, while in no4 way interferlng with the freezrevent nevertheless the continuous block. In'- formation of a so ticular place or places is so reduced that no i cutting manipulation is p t .to come apart along the lines of intended shown at 25.

uired to cause it subdivision. `As a" matter of'fact, the block usuallyfalls apart on leavin the canas indicated in F 2. Obviou y these diaphragms shoul prevent avoidablereduction of the capacity of the cans. Material in sheet-form is therefore used which by preference should be of va character which does not favor .adher- `1n the sheet as Since material which is a temperavture-conductor -favors formation of ice,

sheets of such material (any sheet-metal) would cause ice toV form over them and across the can,closing the openings inthe sheet before the water below the sheet has frozen. This would interfere with thev free movement, during freezing of the water s o entrapped 'and cause distortion of the d1 viding-sheet, or of the can.' To obviate this diiiiculty, material which does not favor such conditions is used. -Such materials are wood, paste-board, celluloid, rubber and similar materials which do not readily conduct temperatures.

Such materials require a protective coating serve them against moisture, for w ich urpose any material, not soluble in water, ike varnish, paint, parain etc.- may be used.

-,Materials of that kind 'also prevent adherence to the ice and favor ready separation.

' ASuch a protecting coating may alsobe obtained by inclosing a sustaining sheet 'between vsheets vof protectinigmaterial, which latter may b e sheets of o aper, or paraffin-paper as indicated in lig. 6s Such a, com site plate or one of material having cient rigidity may be held a shape by springs 15 are used at the edges be las thinv as possible to,

4sheets are urpose, one or the partition. A brace 24 fit to' prea sustainin frame as shown at 18 inFig. 6. These dividing-sheets are held inv proper position by suitable meansv as straps 13, for instance en aging them at their edges and having hoo s 14,- to support them in the can. pressure is also suilicient,.since these sheets are not subject to any iniuence tendiilg to shift them, and their position becomes y. xed as soon as the freezin v means are shown in 1gs. 4 and 5, where ofthesheet which in Fig. 5 are attached thai-insideo the can and in Fig. 4, they areattached to the sheet at the edges thereof as shown at The frictional contact of spring` rocess starts. l Suchr 16. In either vcase they yield when the ice v slid out.

Another form is shown in Fig. 3, Where- :firing-actuated contactieces 17 'are used, idingly fitted into housings at the edges of 'the sheet and similar to a spring-catch or lock-bolt. These holding-means should be so located that none of them are onthat side upon which the block rests while sliding out o the can (see Fig. 2)., The cans are uite dee varying from 5 to 84 feet'fo'r bloc ice an more for the containers in the case of plate ice. Asuitable holding-implement is therefore required to glace the dividing sheets in position. Suc an im lement is shown in Fig. 3, 19 being its ysha v which is of a length suiiicient for the purpose. Means permitting temsorairy' attachment wof the rovi ed at its lower end which may be in orm of s 21 and are ada ted to engage with lugs 2 on the u per si e of to engage the upper edges of the sides of the can and which is attached to shank 19 determines the depth of insertion. A turn in proper direction by means of handle 23 serves to disenga e t e implement. Observe also Fig. 4:.

`or larger containers particularly plateice, provision, may also be division. In plate-ice, due regard must be made for vertical 'viding sheets to clear any means as for instance the hfter-rods referred to before which are frozen into the ice and whereby the same is raised out of the water.
