ICE-CAN.

Specification of Letters'ratent.

Application filed July 29, 1919. Serial No. 314,088.

the art that receptacles or containers of this character are subjected toconsiderable internal pressure during the expansion of the water as it is converted into ice; in the lifting and dumping of the molded block of ice in the-receptacle; and in the general handling, packing and arrangement of; the receptacles .in the main freezin tank.

It has also been found with the. use of priofdevices of this character that when the pans'or receptacles areov'erturned to release the block of ice they are impacted'with considerable force under the thrust of the block o'f'ice, which weighs between one hundred that the seams of the receptacle are burst and opened during'such operation. Another disadvantage found with prior receptacles or molds of this character is that the corners are not capable of withstanding the internal ressure and frequently crack or burst. epair ofsuch injuries to the can cannot be permanently or easily made and the cans are practically worthless when so split. A further disadvantage found inprior molds is that the bottoms, under the heavy strain and the expansion incident to the freezing of the water, causes thebottoms to bulge downward within the base flange and form ice blocks with rounded bottoms making the blocks diflicult to handle asthey will not stand upright, particularly when'depesited delivery wagons and the,

like. q

The object of the present'inventio'n is to provide in a simply constructed sheet metal mold or receptacle a construction which obviates al1 of the above disadvantages and which-has additionally the advantage. of quickly freeing the block of ice when the can is overturned and of reducin the frictionalcontact, between the sides o 'the bl oclr f formly andthe can during the withdrawal of the block of ice.

Anotherobject of the invention is to provide a construction of mold which may be knocked down and conveniently shipped from the factory to ice plants and the like, and which may be stored in quantities in a relatively small space, the object also embracing a novel joint between the meetin edges of the sheet metal body of the can and the bottom edge of the body and the bot- With these and other objectsin view, the inventionconsists in certain novel combinations and arrangements of the parts as will more fully appear as the description pr'oceeds, the novel features thereof being pointed out in the appended claims.

For a vfull understanding of the invention, reference is to be had to the} following desciipltlion and accompanying drawings, in w 10 Figure 1 is a side elevation of a receptacle Patented Aug. 3,1920. I

wallsofthe mold when the block is being extracted The body 10 has its rounded corbursting or splitting of .the metallic body 10 at the corners.

The body 10 may be made in one or more sections, two being shown in the present instance, and which are so constructed that ,when assembled the'sections or sheets of the body meet and overlap at the longitudinal sides of the body so that the narrow sides of the body are uninterrupted and continuous; thus eliminating the formation of seams at such narrow sides where impact and pressure are constantly exerted during handling-of the molds and the dumping of thesame. As shown in Fig. 6, the seams in the body 10 are each formed of the overlapping ends of the adjacent sheets of metal and which have interposed between them a strip or layer 18 of tar paper, or other suitable substance forming a packing for effectively and positively sealing the 'joint between the overlapping ends and for rendering the seam air and moisture tight.

In the present instance the seam is held together by a longitudinal row of bolts'14;

carryin detachable nuts 15 at outer sides 0 the body 10, the bolts being arranged in staggered relation throu bout the end of the can and being detacha 1e so that the sections of the. can may me sepa-' rated and the can thus conveniently handled in relatively small space. By virtue of the tapering formation of the body .of the can, the sections thereof may be made to telescope or interfit when the sections are separated one from the other, and thus a large number of cans may be knocked down and packed into the same space which is ordinarily required for the storage of one 1 10 by bolts 1 Each section of the can is thus substantially U-shaped and the seams of the as sembled can are located in the longitudinal sides of thecan so that the seams are protectedfrom impact and do nothave to sustain the weight of the molded block as the can is overturned or dumped.

The upper edge of the'can may be reinforced by a ring 16 which may be of any suitable construction and detachablyl secured to the u p'er edge portion of the body which may be readily' removed for knocking the structure down; llhe lower end 'of the can is closed by a bottom formedofsheetqmetal which has its marginal. edge portion bent downwardand rounded upwardly. to form a U-shaped channel flange 19 at the margin of the bottom 18 with the flange opening ,upwardly as it comprises a .pair of spaced walls capable of withstanding considerable impact and weight and which braces the bottom portion of the can body 10. Detachable bolts'20 may be used in securing the bottom of the can or mold 10 to the lower edge of the sheet metal body for facilitating the knocking down of the mold. In order to seal the bottom of the body-10, a U-shaped packing strip 21 of tar paper, or other suitable yielding insulating vmaterial may be employed. As shown in Figs. 3 and 5, the packing strip-21 is of U-shape and fitted in the flange 19 about the lower edge of the body 10 and adapted to receive the bolts 20 therethrough for maintaining the packing in position and sealing the packin flange 19. g The bottom' 18 is re nforced agamst bulging downwardly by the provision of ribs. or crimps 22 which are formed diagonally across the bottom and intersect at the intermediate .portion in the thereof: The crimps 22 projectupwardly into the can so asto provide a substantial brace with the arch of the brace upward against the mass'to be supported,the arch being formed by the upstruckU-shape of the IlbS.

A can constructed according to this-invention is of substantiallynormal size and may be handled in the main tank in the usual manner. Whenthe can is dumped over on one of its narrow sides the impact ofthe weight of the can with the molded block therein is not thrust directly upon the seam of the body, and thus the seam is protected against this impact which usually opens theiseam and destroys the can. Furthermore, the arrangement of the seam intermediate the lon itudinal sides of the can strengthens said sides and forms a reinforcement for the can to resist internal what we claimas new and desire to secure;

1. A knock down ice mold comprising a rectangular body portion, which is divided longitudinally; into twocomplemental U shaped sections, adapted to be nested in each other, means for detjachablyconnecting the meeting 'e'dges-of ithe, sections to form ahollow body for the mold, a bottom plate having marginal portions constructed to receive and interlock with the edges of the body, and means fordetachably securing the bottom plateto the body of the mold.

2. A knock down ice mold comprising a rectangular body portion which is divided longitudinally into two complemental' U shaped sections adapted to be nested in each other, the meeting edges of the sections overlapping each other when the sections are operatlvely assembled, fastening members detachably connecting the overlapping edges of the sections, a bottom plate formed with a marginal channel flange receiving the lower edges-of the body sections, and means for det'achably securing the bottom plate to the body sections.

3. A knock down ice mold comprising arectangular body portion which is divided longitudinally into two complemental U shaped sections adapted to be nested within each other, the meeting edges of the sections overlapping when the sections are operatively assembled, bolts detachably connecting the said overlapping edges, a reinforcing band applied to the upper end of the sections, a bottom plate formed with a marginal channel flange receiving the lower edges of the body sections, and fastening members :detachably securing the bottom.

plate and top band in position.

In testimony whereof we afiix our signatures.
