SPECIFICATION forming part of Letters Patent No. 756,094, dated March 29,1904.

I Application filed July 31, 1902. Serial IIO- 17,900- (No model.)

To all. whom, it concerns Be it known that I, WALTER E. BROWN, a citizen of the United States, residing atCarrollton, in the county of Carroll and State of- Missouri, have invented a certain new and useful Cabinet'for Brick Ice-Cream, of which the following is a full, clear, and exact description, reference being had to the accompanying .drawings, forming part of this specification, in Which Figure l is a perspective viewof a cabinet having compartments or tunnels to accommodate eight (8) trays or drawers. Fig. 2 illustrates the cabinet positioned in an exterior casing, which may represent an ice-box or refrig'erator. Fig. 3 is a detail of one of the trays or drawers.

In carrying out my invention I construct the shell of the cabinet substantially square or rectangular in horizontal and cross section,

so as to form the vertical front and rear walls a a and side walls 6, said shell havingan open top 0 and a closed bottom (Z and a discharge 0 through one side through which water may be drawn to drain the cabinet. The cabinet is also constructed with any desired number of horizontal tubes or tunnels B, which are rigid therewith and which extend in parallel series and connect with the walls a a and open through and whose open ends are flush with the front wall, as shown in Fig.1.

These tubes or tunnels are spaced from each other both horizontally and vertically, and although I have shown a double row of tubes it is manifest that other arrangements may be used without departing from the scope of my invention. The spaces between'the tubes and the spaces between said tubes and the inner sides of the shell are to be filled with a refrigerating materialsay ice and ice and salt to produce the required degree of temperature for the purpose of refrigeration and preservation.

In connection with the shell and tubes, as

before described, I employ suitable trays or drawers D, such as are shown in Fig. 3. These trays are of shallow depth vertically, and their width is about equal to the width of the tubes into which they are to be inserted. Each tray consists of sides, 'a bottom, and a the introduction of the tray into the tube.

Each tray also has a handle portion 6, by which the tray may be easily inserted and withdrawn.

The cabinet described may be used without an exterior casing; but better results and economy in the use of the refrigerating material used will be obtained if the cabinet is placed with an ice-box or refrigerator E with packed wall of non-heat-conducting material, as shown in Fig. 2. This refrigerator or outer case has a top door which when let down forms a closure for the upper open end of the cabinet, and it also has'a front door which when open exposes the handled fronts of the trays and allows any one or more trays to be removed.

In my invention I may construct a cabinet with four, (4,) six, (6,) eight, (8,) ten, (10,) or any other number of tunnels,each of which has a circumscribedspace that in practice will be packed with ice or other refrigerating material. teen (19) inches long, thus giving each tube a capacity for three bricks of cream, constituting a commercial quart. The trays being shallow, the cream is exposed to the direction of the cold air in the tubes, and as eachtube is surrounded by the refrigerating material each brick of cream is subjected to a low temperature, which v is to be preferred to the method of stacking the bricks in a single large compartment where only the vertical side walls of the bricks are exposed to the action of the refrigerating material and where the middle portion of the brick would not be frozen as hard as the outer sides. In practice the cream is put into paper boxes, which in turn are placed in the trays, and when an order is to be filled for brick-cream the tray containing the desired kind is withdrawn, the amount of cream extracted, and the tray again The tubes may be approximately ninereplaced. The apparatus is also useful for freezing what is known as soft cream in two or three hours after the same is placed in the tubes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cabinet for preserving brick icecream, the combination of a shell having tubes or tunnels extending horizontally through it in parallel series said tubes or tunnels connecting rigidly with the front and rear walls of the shell and forming an immovable part thereof and said tubes having their front ends opening through the front wall of the shell, and said tubes separated from each other on all sides to allow a refrigerating material to inclose the same, and removable trays fitting the tubes or tunnels and having front walls forming closures for the open ends of the tubes.

2. An improved cabinet for preserving brick ice-cream consisting of a shell having vertical, parallel walls and a bottom, and having an open top, tubes extending horizontally through the shell from front to rear thereof and having open ends exposed through the front wall, said tubes parallel and separated from each other to form surrounding spaces for refrigerating material; trays fitting the tubes and having enlarged front plates to engage the front wall of the shell and form a closure for the open ends of the tubes; and an exterior box or case having a top door which, when closed, forms a closure for the open top of the shell, and a side door affording access to the trays and open ends of the tubes.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 8th day of July,

WALTER E. BROWN. Witnesses:

T. J. ROBINSON, H. G. EDWARDS.
