APPARATUS FOR MAKING ICE.

To all 2072 am it may concern Be it known that I, WASHINGTON EVERETT PARSONS, a citizen of the United States, and resident of the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Making Ice, of which the following is a 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 invention has particular reference to the means for connecting the main brine supply conduit with the interiorly arranged circulating means.

The objects of the invention are to provide 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 interior, circulating means, said pipe being arranged on the exterior of the cans and connected with outlets in the said main by readily detachable means held in cooperative relation by the buoyant effect of the brine in the tank on the can.

It has been heretofore customary to provide the cans with a heavy bottom for the 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 and to utilize the buoyancy of the brine to hold the pipe which conveys the brine to the interiorly arranged circulating means, in cooperation with the outlet from the main supply conduit. The pipe for conveying the brine from the supply conduit to the interiorly arranged circulating means is located on one side of the can and therefore the buoyant eifect of the brine on the can tends to tilt the latter and, in order to obviate this tilting action, I have provided means above each can for holding the latter in proper position.

A further object of the invention is to provide a readily detachable connection between the said pipe at the side of the can and the main supply conduit so that the can may be readily placed in or removed from the tank.

Other objects and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings in which,

Figure l is a longitudinal section through Specification of Letters Patent. Application filed December 20, 1912.

Patented Nov. 17, 1914. Serial No. 737,907.

a water can and showing its relation to the ad oining cans in the usual freezing tank; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is an enlarged section on the line 38 of Fig. 2; Fig. 4 is an enlarged section of the pipes at the bottom of the can for conveying the brine to the interiorly arranged circulating pipes; Fig. 5 is a section on the line 55 of Fig. 3.

Referring to the drawings, indicates a portion of a freezing tank having a bottom 11, and having at its top the usual cross beams 12, 13 and 14 which form spaces through which the water cans 15 are passed in being placed in or removed from the tank and support the covers for these spaces. The tank is usually filled with brine to a level slightly below the tops of the cans 15 and the brine is cooled by being circulated from the tank through a suitable coolingapparatus and then returned to the tank, or the tank may have arranged therein, between the rows of cans, the circulating pipes 16 for the brine cooling medium.

I provide 011 the interior of the cans the upwardly extending pipes 17 which are closed at their upper ends and have their lower ends open to the interior of the tank, as clearly shown in Fig. 1. \Vithin the pipes 17 are the smaller pipes 18 which are connected below the bottom of the can with a suitable supply conduit. This conduit is preferably formed with the reducing Ts 19 by means of which the size of the conduit is reduced beyond each T so as to provide a more positive circulation of the brine through each of the pipes 18. Referring to Fig. 4, it will be seen that the conduit is provided with an L 20 at one side of the can and this L is connected with the first of the Ts 19 by means of a pipe section 21. Beyond the first T 19 is a pipe 22 which is smaller than the pipe 21 so as to restrict the flow of brine and cause the same to rise in the pipe 18. From Fig. 1 it will be observed that the pipe 23 which is beyond the second T 19 is smaller than the pipe 22. The L 20 has one of its openings directed upwardly at the side of the can and connected with a pipe 24 which has at its upper end a special fitting 25 secured to the side of the can.

Arranged below the beam 14? is one of the main brine supply conduits 26, which is provided in its bottom adjacent the fittings 25 with special outlet fittings 25 which areshown in detail in Figs. 3 and 5. These fittings are secured to the lower side of the conduit 26 and have a baffle or deflector 27 extending upwardly into the conduit 26 with the open side 28 thereof directed in opposition to the flow of brine through the conduit so that the brine will be deflected through the fittings 25. Below the conduit the fittings 25 are provided with two

branches

29 and 30 adapted to be connected with the fittings 25 on adjoining cans so that the interiorly arranged pipes in two cans will be supplied from one outlet in the conduit 26. The

passages

29 and 30 are preferably oval in form, as shown in Figs. 3 and 5 and the fittings 25 are each provided with a recess 31 in the upper side thereof in which is arranged a suitable gasket 82. Each fitting 25 is provided with a central passage 33 which communicates with the

passage

29 or 30 and the lower edges of the walls of the

passages

29 and 30 engage the gaskets 32 and have a certain amount of lateral movement thereon so that a tight joint may be provided between said'lower edges and the gaskets without having the parts in exact alinement.

The buoyancy of the brine in the tank on water cans of the usual size causes the cans to be forced upwardly so that the fittings 25 on the cans will be pressed against the lit tings 25 on the conduit 26. The engagement of these parts prevents the upward movement of that side of the can and therefore the can has a tendency to be tilted. In order to hold the can down to its proper position, I arrange on the underside of the cover 34. for the space above each can,.a cleat 35 which is adapted to engage the upper edge of the can on the side opposite the fitting 25, as shown in Fig. 1, so that the can will be subjected to the weight of the cover.

It is believed that the foregoing description taken in connection with Fig. 1 will make it perfectly clear how the can is held, in the position shown, against the buoyant force of the brine in the tank. When it is desired to remove a can from the tank, as when the water in the can has been frozen, the cover 3a is removed and the can pressed downwardly to permit disengagement of the fitting 25 from the fitting 25 on the conduit 26. This disengagement is effected by moving the can laterally to the left in Fig. 1. Vhen the parts are disengaged the can may be readily lifted out of the tank and replaced by-another can by a reverse of this operation. When the can is being lifted out of the tank the suction in the pipe 17 will draw practically all of the brine out of the pipes 18 and the pipes connecting them with the fitting 25.

In order to protect the pipes at the bottom of the cans the latter are provided with suitable leg-s 36, by means of which the cans may be supported when out of the tank without the pipes being subjected to the Weight thereof.

By having the conduits 26 arranged at the top of the tank 10 instead of at the bottom of the tank, as has been the custom in prior systems employing the internally arranged circulating pipes in the water cans, the conduits are readily accessible for repairs and other purposes and it is possible to use a much lighter can and at the same time have a thoroughly efficient connection between the conduit and the interiorly arranged circulat-- ing pipes.

It will be obvious to those art that various changes may the details of construction and arrangement of the parts of my invention, within the scope of the appended claims, and therefore I do not wish to be limited to the exact details shown and described.
