IOE-MAKIN Gr APPARATUS.

To all whom it may concern:

Be it known that I, WILHELM Gnmssnn, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Ice-Making Apparatus, of which the following is a specification.

The present invention has reference to improvements in ice making apparatus, and more especially in the formation of the building, room or other structure wherein the freezing operation and the subsequent re-cooling of the refrigerating medium take place.

It resides primarily in the provision of a refrigerating structure containing separate tanks or chambers for the carryingout of the two operations specified, the arrangement of parts being such that thebrine is caused to circulate through the freezing tank or chamber, and, on leaving that chamber, to enter a second chamber or tank wherein it is cooled and then discharged into a pump or similar operating element which again forces it into the freezing tank. By reason of this arrangement, the employment of cooling coils, or the like, in the freezing tank or chamber is obviated, and, in consequence, the trouble and difliculty ordinarily attendant upon the cleaning and repairing of such coils.

The invention also comprehends certain further improvements, hereinafter specified, in the construction of the tanks or chambers themselves and the therewith directly associated parts or features.

A structural embodiment of the invention is illustrated in the accompanying drawings, wherein-- Figure 1 is a plan View, with parts broken away and in section, of the improved freezing and brine-cooling tanks. Figs. 2, 3 and 4 are fragmental vertical sections on enlarged scales taken, respectively, on the lines 22, 3-3 and 4-4 of Fig. 1; Fig. 5 is a fragmental perspective view, partly in section, showing the construction of one of the main supporting beams employed in the freezing-tank; and Fig. 6 is a perspective view of one of the connecting beams associated with said main beams.

The structure shown in the said drawings is designed primarily for the manufacture of the so-called can ice, but the circulating system employed may be used with equal facility in manufacturing plate ice,

and it will be understood, therefore, that such of the appended claims as relate to said system convey no specific limitation to the making of either kind of ice. Said structure'is preferably built or constructed, in the main, of concrete, and comprises essentially the two side walls 7 and 8, the outer end wall 9 and the bottom wall or foundation 10, the several walls having their inner surfaces preferably lined or faced with terra-cotta tiles or the like, as indicated by the numeral 11, which are, in turn, faced with a layer 12 of cement or concrete. The bottom wall 10 is also preferably provided with an insulating filling 13 of cinders or the like. Between the two side walls extends a transverse partition wall 14 which forms the inner end wall of the several main chambers or tanks hereinafter described and is constructed in the same manner as the other walls, the said side walls and the bottom wall being extended beyond this wall or partition until they'meet the inner end wall (not shown) of the building proper. Thespace inclosed by the walls 7, 8, 9 and 14 is divided longitudinally by a main partition wall 15, one of the two chambers thus formed (indicated by the numeral 16) constituting the freezing chamber, while the other chamber is divided longitudinally by a wall or partition 17 to produce the brinecooling and

discharging chambers

18 and 19.

The freezing chamber is roofed by a grid like structure 20 comprising main beams 21 and crossor connecting-beams 22. The beams 21 are, in the construction illustrated, arranged transversely of the chamber, and their ends are supported in seats or pockets 23 formed in the walls 8 and 15; they are preferably constructed in the manner shown in'Fig. 5, and consist each of a skeleton frame work of metal, and a filling or body of cementitious material 24. The said frame work itself comprises upper and lower pairs of longitudinally-arranged angle bars 25 and 26 connected together at intervals by straps 27 and cross-bars 28, a series of longitudinally-arranged tie-rods 29, and a similarly-arranged undulatory tie-rod 30, the frame work being placed in a mold which is subsequently filled with the cement or concrete. The upper portion of each beam is slightly reduced in width to produce the continuous longitudinal shoulders 31 upon its opposite side faces, the latter being alsoformed at intervals with

vertical seats

32 and 33; the seats 32 terminate short of the bottom face of the beam to produce the shoulders 34, while the seats 33 have the shape of a bayonet-slot. The cross-beams are in the form of separate blocks whose endsfit in the seats 3'2 and are supported upon the shoulders 34.

The above described arrangement of the beams comprising the grid 20 is such that a series of rows of spaces or compartments will be produced, the side walls of each compartment being provided with centrally located seats 33. In each compartment is disposed a suitable can 35 whose top has secured thereto a bar 36, or the like, the ends of which are engaged and held in place in the horizontal arms or branches of said seats, thereby maintaining the can in properly submerged position. The cans are, however, omitted and replaced by other suitable devices where the manufacture of plateice is contemplated, as will be understood. The grid is floored over in the usual manner by the removable covers 37 which rest upon the upper faces of the beams 21 and, also, upon the shoulders 31.

The brine or other refrigeratingmedium is supplied to the freezing chamber 16 from a longitudinal pipe 38 arranged between wall 8 and the first longitudinal row of cans and provided with a series of laterallydirected nozzles 39 corresponding in number to the number of cans in such row. Said pipe extends at its inner end through an opening in wall 14 and is jointed at that point to a pipe 40 leading from a force pump 41 or like motive element arranged within a chamber 42 located at one end of the cooling and

discharge chambers

18 and 19. This pump may be of any suitable type and may be driven in any preferred manner.

The brine flowing through the nozzles 39 into the freezing chamber, fills the latter and surrounds the cans therein up to a point approximately level with the lower faces of the pockets 33, the wall 15 being formed at about the point indicated with a series of openings 43 through which the brine flows into the cooling chamber 18. Through this chamber extends a cooling device 44 here shown as in the form of a longitudinal drum or cylinder containing a refrigerating medium, the brine, which. has become heated during, its passage through the freezing chamber, being re-cooled on coming into contact with said device, as will be apparent.

The wall 17 which separates the cooling and discharging chambers, is formed at its bottom with a series of outlet apertures 45 through which the cooled brine flows into the discharging chamber. In said discharging chamber there is provided a vertical partition wall of concrete 46 whose top edge lies in the same horizontal plane as the bottom faces of the openings 43, between which wall and the adjacent wall 7 is formed a downwardly inclined gutter or trough 47 opening at its lower end through wall 14 into a pipe or spout 481 that leads into pump 41. The two

chambers

18 and 19 may be roofed over with a covering of removable sections 49 similar in thermain to the covers 37 and provided for much the same purpose, the said covers 49 being supported upon the shouldered upper ends of the walls 15, 17 and 7; Said chambers may also be provided with intericrly-located braces 50 designed to strengthen the walls 15, 17 and 46.

The operation is substantially as follows: Brine is forced from pump 41 through pipe 40 into the. pipe 38, from which latter it flows through the nozzles 39into chamber 16, filling the same and freezing the water contained in the cans. From said chamber it flows through the outlets 43 into the chamber 18, wherein it is cooled by its passage around the drum or other device 44. On leaving chamber 18 through the outlets 45, it fills chamber 19 and overflows into the trough or gutter 47 whence it is returned to said pump and again forced into pipe 38 for re-circulation.

It will be observed, therefore, that a continuous circulation of the brine is provided for, during which time it is re-cooled upon leaving the freezing chamber. Also, the disposition of the cooling device in a chamber separate from that wherein the ice is formed enables such device to be readily inspected and cleaned, thus reducing the time consumed in said operations and obviating the difficulties ordinarily connected with the same. The building itself possesses a maximum degree of strength, rigidity and durability, owing to its substantially integral formation.
