REFRIGERATING DEVICE.

To all whom it may concern:

Be it known that I, MARK E. STOVER, a citizen of the United States, residing at Detroit, in the county of lVayne and State of Michigan, have invented a new and useful Ice-Making and Refrigerating Device, of which the following is a specification.

My invention relates to improvements in the freezing-tanks of refrigerating and icemaking machines; and the objects of my improvement are: first, to provide a continuous, positive and rapid circulation of a cooling medium, such as brine, around each ice-can in the tank so as to freeze the contents thereof with the greatest possible rapidity; second, to provide an ice-making and refrigerating device in which the amount of brine circulating around each icecan shall be substantially equal in temperature and rapidity of circulation throughout the entire tank, thus producing a uniform freezing of the contents of the ice-can; and third, to provide an ice-making tank which shall be composed of compartments so constructed that the cooling medium may be cut off from any desired number of the said compartments without affecting the balance of the tank. I attain this object by the device illustrated in the accompanying drawing, in which a perspective view of my improved device is shown.

A represents the outer wall of the freezing tank, of any desired construction. The tank is divided into a plurality of compartments by longitudinal partitions B and transverse partitions C. These partitions may. be joined to the bottom and sides of the. tank in any desired manner, such as by riveting or soldering, but their tops are sufliciently lower than the outer walls of the tank to permit the brine to rise and flow over the partitions without overflowing the tank. Each compartment is adapted to receive an ice-can, D, supported in any desirable manner such as by bars E, placed near the bottom of each compartment. It is desirable that the cans should be of such depth that, when placed in position in the compart ments, the tops of the said cans shall be sufficiently above the tops of the said partitions to permit the flow of brine over the said partitions without allowing it to flow into the cans. The cans are of sufliciently smaller dimensions than the compartments in which they are placed to allow the brine Specification of Letters Patent.

to circulate around them on all sides. The brine is supplied to the lower part of these compartments by a series of pipes F, with suitable nozzles Gr so placed as to admit the brine, at the center of each compartment and below the ice-cans. A pump H forces the brine through the pipes into each compartment, compelling it to rise around the cans and to flow over the tops of the partitions into the brine-cooler I at one side of the tank. Here the brine is cooled by suitable means, such as flowing over cooling pipes J and is drawn from the lower part of the compartment I by the brine pump H, thus making a positive, complete and rapid circulation around each ice-can.

By making the longitudinal partitions somewhat higher than the transverse partitions, it is possible to divide the freezing tank into a series of batteries; and by providing the pipes of the circulating system with suitable valves K, the brine may be cut off from any number of batteries Without affecting the operation of the balance of the tank.

I claim:
