AUGUSTUS R. KENNEY, OF SAN FRANCISCO, CALIFORNIA.

ICE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,829, dated July 21, 1885.

Application filed March 6, 1885.

- of the city and county of San Francisco, Statel of California, have invented an Improvement in Ice-Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a new and useful ice-machine; and it consists in a box having a sloping bottom and provided with a peculiar vertically-moving end-gate,Wedge-shaped and independent, and water tight closed partitional cans within the box provided with evaporatingcoils, peculiar agitators within the cans and within the compartments of the box formed by the cans, mechanism for reciprocating the agitators, and inlet and overflow and drain pipes and valves by which the cans arel supplied, regulated, and drained, all arranged and operated in the manner I shall hereinafter fully describe.

My invention-further consists in vdetails of construction relating to the end-gate, the cans, the agitators, and other parts.

The object of my invention is to provide a simple, practical, and effective ice-machine,

the several advantages of which I shall de-,

scribe during the course of the speciiication.

Referring to the accompanying drawings, Figure l is a perspective view of my ice-machine. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a vertical longitudinal section. Fig. 4 is a perspective detail showing one of the refrigerator-cans in position, its side being broken away to show the interior.

A is a box, having in its ends and bottom the grooves a. B are frames, of wood or other non conductor, the bottoms and ends of which fit within the grooves a of the box, whereby they can be removed at pleasure, Fig. 4. The frames inclose or encircle cans G, and form a non-conductor around them, removing them from the ends and bottom of the box. These cans are independent of each other. They are water-tight and wedge-shaped, the apex being downward and the base at the top, Fig. 2.

Vithin each of the cans is the coil D,which consists of a pipe bent or curved vertically, and joining the cans through their tops, as shown. The entrance end of the coil is pro- (No model.)

vided with a valve, d, and its exit end is provided with a similar valve, d.

On the top of the box and cans is a frame, E, consisting of transverse end bars or strips and longitudinal bars or strips, the latter of which carry the agitators F, which consist of slats extending downward into the compartments of the box, which are formed by the cans. The frame E is mounted on small rollers e, whereby it may easily receivel a reciprocating movement. z

Within the cans are the two-part or slotted agitators G, which extend downwardly,strad dling the coil, and are mounted on longitudinal strips g having small wheeled trucks g on each end traveling on short tracks g2, whereby the agitators are `adapted to receive a horizontal reciprocating movement, which is imparted by means of stems g3 extending through the rear end of the cans and box connected with the wheeled trucks. These stems may be connected to receive a simultaneous movement, or they may be moved separately. lVith one of the stems the frame E, which carries the agitators F, is connected by means of a pitman, c', and a bar, c2, whereby the agitators F are reciprocated simultaneously with the agitators G.

It will be observed that the cans C are so located that they divide the box into compartments, the end or side ones of which are narrower than the others. The cakes of ice being frozen from the sides ofthe can only and are not intended to meet, it is obvious that in the central and larger compartments there will be two cakes, and in the end compartments but one. The two cakes in the same compartment are not allowed to meet, (as before mentioned,) and in the body of unfrozen liquid between them the agitators F operate. These are therefore located centrally; but in the end compartments they are moved beyond the central longitudinal line, in order to allow the proper space for the formation of the single ice cake. The cans are stidened by rivets X,

which pass through each from side to side.

Each can is supplied with a feed-pipe, U, at its top and with a drain-pipe, I, at its bottom, controlled by a cock, i, and united to an escapepipe, J. They are also provided with overliow pipes K, controlled by cocks 7c, joined to a common discharge-pipe, L. Thr! IOO iioor or bottom of the box A slopes downwardly from the rear to the front.

Secured to the front of the box are suitablyl forms the front end of the box, and consequently,when pushed up, opens said end. It is accurately balanced by means of the chain or cable N, which passes upward toa beam in the ceiling and over suitable pulleys,and has a weight, W, attached to its other end.

In order to cause the gate to form a close and water-tight joint with the front ofthe box, I have upon the sides and bottomof the box the elastic or rubber packing or washers O. A bracket, l?,is secured to the end of the box, and in its front bar, p, is a binding-screw, Q, the end of which is adapted to bear against ribs upon the gate, and thus to force said gate against the rubber packing or washers,where by a close joint is formed.

The bar p of the bracket is maderemovable by reason of fitting in suitable sockets or slots in the end of the arms of the bracket.

The operation of the device is as follows: The gate is lowered, and by means of the binding-screw is pressed tightly to its seat. The sweet water is then poured or allowed to flow into the compartments which the partitional cans form in the box, and then brine or other suitable freezing liquid or agent is supplied to the cans themselves through the supplypipes U, the overfiow-pipes K indicating the quantity to be supplied and when to stop the iiow. The evaporating-fluidisthenintroduced into the coil-pipe D, and at the same time the agitators G F are reciprocated within the com partments and cans.

The object of the closed cans is to prevent variation from outside temperature and con- I centrate the cold against the sides, not letting it escape, while the object of their wedge shape is as follows: As before explained,each cake is frozen outwardly from the sides only of the cans. These sides being inclined by reason of the wedge shape of the cans, the A cake is consequently frozen in a slightly-inclined position, which gives it a tendency, when loosend from the side of the can, to tip over, thereby freeing itself more completely. The cakes are not frozen wedge-shaped, but rectangular,though in an inclined position.

I am aware that an ice-machine is known in which the freezing or sweet water comparu ments are wedge shape in transverse section; but in this machine the cake of ice is made to fill the entire compartment, and therefore is dependent more upon the shape of the compartment itself than upon any partitional cans, while in my machine my result is more dependent upon and relates particularly to the inclined sides of the partitional cans without any reference to the shape of the compartments, because as my ice cakes do not fill the compartment and are frozen' outwardly in --straight lines from the cans, they are consequently rectilinear and lie in an inclined position. In the machine referred to this is not the case, for the cake is a solid one, and is frozen from the top as well as the sides, and is thereby not in an inclined position. My partitional cans are moreover independent of each other. The agitators within the compartments promote the freezing process, and those in the cans equalize the temperature of the freezing agent. The frames B, forming nonconductors holding the cans away from the box, keep the ice cakes free thereof, as they form on the sides of the can only.

The sloping door of the box enables the operators to withdraw the cakes with greater facility.

When the sweet water is frozen, the controlling-cocks of the escape or drain pipes of the cans are opened, and all the brine or other freezing agent is drawn off. The controllingcocks of the evaporator-coil are also closed, and the feed-pipes of the cans are opened and sweet water or steam or any melting agent is forcedV or allowed to flow into them. This agent melts the edges or sides of the cakes,

by their tipping or inclined position. After remaining for a suitable length of time the Sweetwater or other melting agent is drawn off in the same manner that the brine or other freezing agent was drained. The end-gate is then raised, and the blocks of ice are slipped out. When the end-gate is first raised, and before the cakes are `taken out, the unmelted water is rst allowed to escape and is carried off suitably.

The front bar or the bracket is removed from the end arms in order to allow the cakes to be slipped out.

The box A is provided with a cover, T, over all.

By the arrangement of supply and drain pipes and the controlling-cocks of said pipes, and the evaporator-coil, the machine herein described is well adapted to form one of a connected series the members of which may be simultaneously operated, or one or more may be cut out of the series and operated separately. Y

It is intended that the supply shall be effectedby gravity, and that suitably-inclined floors or chutes shall be provided in front of the boxes, by which the ice cakes may be run off with little trouble. f
