APPARATUS FOR MAKING ICE.

Specification of Letters Patent.

Patented Feb. 1'7, 1914.

Application filed January 30, 1913. Serial No. 745,237.

To allaohom it may concern:

Be it knownthat I, WVAsHINGroN EVERETT Parsons, a citizen of the United States, re-

of New York, have invented certain new and useful Improvements in Apparatus for Making Ice, specification.

This invention relates to ice-making apparatus and more particularly to systems in which the ice is made in cans provided with interiorly arranged brine-circulating means.

The invent-ion has particular reference to main with the interiorly arranged circulating means.

This invention consists in certain improvements in the apparatus shown in my prior application No. 737,907, filed December 20, 1912, and has for its objects the provision of the usual freezing tank with a brine supply main arranged in or adjacent to the upper part thereof, where it is readily accessible, and to provide the cans with suitable supply pipes for the interiorly arranged circulating means, said pipes being arranged on the exterior of the cans and connected with outlets in said main by readily detachable means held in cooperative relation by the buoyant effect of the brine in the tank on the cans.

It has heretofore been customary to provide the cans with a heavy bottom forthe purpose of weighting them to overcome the buoyancy of the brine, and it is one of the objects of my invention to have a lighter can, which is less expensive to manufacture and may be more conveniently handled and whereby the buoyancy of the brine may be utilized for the purpose above stated.

The pipe for conveying the brine from the supply main to the interiorly arranged circulating means is located on one side of the can and has a lateral inlet near the top of the can, which is adapted to cooperate with a corresponding outlet in the supply main. In order to hold the inlet in registering re lation I provide means adapted to engage the can at a point adjacent to said inlet and so hold the can that it will be tilted about this point as a center by the buoyancy of the brine in the tank and thereby hold the inlet and outlet in cooperating relation.

Other objects and the features of novelty *1 Fig. 1 and showing 1 vention. Fig. 4 is a section on the line 4l fof Fig. 3 f of the can the means for connecting the brine supply 3 the water cans which v closed at their upper ends jwill be apparent from the following description taken in connection with the acl 5 companying drawings, in which: siding at New York, in the county and State 5 Figure 1 is a central longitudinal section I through a can embodying my present invention and showing the can in relation to the of which the following is a the freezing tank.

brine supply main in the upper portion of Fig. 2 is an enlarged portion of Fig. 1. Fig. 3 is a view similar to another form of the inwith a portion of the side wall broken away. Referring to the drawings, 10 and 11 indicate two of the usual cross beams at the top of the freezing tank, covers 12, the latter which support the forming a flooring above the freezing tank and also covering are arranged in the tank between the cross beams.

A water can or receptacle is shown at 14: and is provided with the interiorly arranged brine-circulating means, of which I have shown three consisting of the concentrically arranged

pipes

15 and 16. The pipes 15 are and have their lower ends secured to the bottom 17 of the can. The pipes 16 are considerably smaller than the pipes 15 to provide an annular passage therebetween and extend through the bottom 17 and are secured in a supply con duit 18. The conduit 18 is secured to the bottom of the can on the exterior thereof and extends to one side of the can and is provided with the upturned portion 19, which communicates with an upwardly extending conduit 20. The conduit 20 is provided with a lateral inlet 21 adjacent the top of the can and the brine flows from this inlet downwardly into the conduit 18 and from the latter upwardly through the pipes 15 and then downwardly through the pipes 16 whence it is discharged through the lower ends of the pipes 16 into the main body of brine in which the can is placed.

Arranged preferably in the upper part of the freezing tank and supported in any suitable manner, as on the under side of the beam 11, is a brine supply main 22 which, as

shown in Fig. l, is formed with a channel 23 constituting its lower side and vertically arranged

plates

24 and 25 forming the side walls of the main and secured to the flanges of the channel 23 and to the beam 11. The

main 22 is also provided with lateral outlets 26, which are adapted to register with the inlets 21 of the conduits 20 for the purpose of supplying the brine-circulating means on the interior of the cans. In order to provide a fairly tight joint between the conduit 20 and the wall. of the main 22 I have arranged therebetween a packing n'ieinhcr 27, preferably of sheet rubber, which may be secured in position in any suitable manner, as by means of tacks or nails 2% driven into the beam 11.

At the vertical corners of the cans adjacent the conduit 22 I secure the lugs or books 29 which, as shown in Figs. 1 and 2, are adapted to engage one of the flanges of the channel. 23 and thereby hold that side of the can against upward movement. The buoyant effect of the brine on the can tends to tilt the can upwardly about the point of engagement of the hooks 29 with the channel 23 and therefore causes the edges of the inlet 21 to be tightly pressed against the packing member 27 so as to not only hold the inlet 21 in registration with the outlet 26, but to also limit the tilting of the can and thus secure the latter in position in the tank. In operating the apparatus the cans, filled with the water to be frozen, are lowered into the spaces between the cross beams of the tank and then pressed downwardly against the buoyant force of the brine in the tank until the hooks 29 are below the flange of the channel 23, then moved laterally to effect engagement of the hooks with this flange. After the water has been frozen the cans are removed by the reverse of this operation.

In Figs. 3 and 1 I have illustrated another form of the invention, in which hooks 30 engage the upper edge of the side of the can having the conduit 20 thereon, and thereby limit the upward movement of this side of the can. As will be observed the books 30 are above the plane of the inlet 21 and therefore it is necessary to provide means for forcing the opposite side of the can downwardly in order to hold the inlet 21 in close registration with the outlet 26. For this purpose I secure to the bottom of the can, adjacent the side opposite to that hav ing the conduit 20 secured thereto, a weight 31 which is of sufficient size to overbalance the buoyant effect of the brine. The upper edge of the can is held in engagement with the hooks 30 by the buoyant force of the brine and the weight 31 causes the can to be tilted downwardly about the point of engagement with these hooks, so that this arrangement accomplishes the same object as that shown in Figs. 1 and 2.

As will be observed from Figs. 1 and 3 the conduit 20 is of tapering cross section so as to have the edges of the inlet 21. as close to the side wall of the can as is practicable.
