COOLER.

SPECIFICATION forming part of Letters Patent No. 336,88Q, dated February 1, 188?.

Application tiled April 152, 1886. Serial No. 198,523.

To ttZZ whom, it may concern;

Be it known that I, ANDREW J. ORR, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Milk-Coolers, of which the following is a specification, reference being bad to the accompanying drawings, in which- Figure l is a front elevation of the cabinet with doors open; Fig. 2, a vertical transverse section of same; Fig. 3, a vertical section on line at, Fig. 1; Fig. i, a horizontal section on line yy, Fig. I; Fig. 5, a plan view of top of cabinet and refrigerating -pan, the cabinetcover being removed; and Fig. 6 is an isometric View of my U-shaped milk-can.

Similar letters or figures of reference indicate corresponding parts throughout the several views.

My invention consists of a milk-can having inner vertical walls bent inwardly and forming a, U shaped millrchaniber. said walls being parallel to the vertical side walls and connected to each other and to the side walls by rounded connections, and having a flat open top, the recess extending up to the top.

My object is to improve the construction of the cooler by making the greater part of the interior in removable sections to facilitate cleaning, and also to improve the milk-can by increasing the area of cooling-surface, and also to obtain a how of the cooling-liquid around the milk-can at all points of its outer surface, and especially in front between the milk-can and the lining of the case. It is constructed as follows:

A is the cabinet, consisting of a wooden case provided with transverse joists 1, upon which I mount the longitudinal stringers 2, the joists and stringers together constitutin g an inclined supportingi'rame to carry the water-tank 3, and located upon an incline above the bottom of the cabinet, about as shown, thus creating the chamber-l. This water-tank is constructed of sheet metal, water-tight. I provide this cabinet with doors in front to permit access to the faucets 5 6 and to the chamber 4, as well as to observe the condition of the milk or cream through the glass ports of the case or watertank. This cabinet has also a removable cover to permit access to the ice-pan 7 and funnels 8. It is also provided with a water-inlet, 9,

opening into the ice or water pan 7, and an overtlowpipe. 10, located at about the top of the milk-can B.

B is my milk-can, constructed oisheet metal, with vertical sides or walls and tight flat inclined bottom, which bottom is provided with the supporting-ribs shown in Fig. 3. The walls of this can are bent inward from one end so as to create a U shaped milkchaniber, the sides of which chamber are separated by the walls 12 13, and these walls are separated from each other to create a walerspace between them. This is the construction shown in Fig. 6 and at the left of Fig. 4.

In Fig. at I show two duplications or extensions of my construction, in that the central milk-can is shown as having two sets of inwardlybent walls, 12 13, creating three parallel mil k-chanihers communicating with each other, and in the milk-can on the right I show three sets of inward] y-bcnt walls, creating four parallel milk chambers, all communicating with each other. In either construction let is the faucet-pipe, only one being necessary, even for the largest milk can. Upon these pipes I screw the faucets 5, the pipes extending down through holesin the bottom of the watentank, provided with a suitable packing to make a water-tight joint, and the faucets are removahly secured below, and when the faucets are unscrewed the milkcans can be lifted out of the cabinet for scalding or other cleansing.

In the front olthe milk-can I cuta vertical port or slot, which I cover and close with a sheet of glass, 15, making a watertight joint in any desired manner. This slot and glass 15 extends from the bottom to the top, or very nearly so, and the glass permits the inspection of the cream.

In the side of the watcrtanlr I cut also a. vertical port or slot, which is covered by a sheet of glass, 16, mounted thereon by a watertight joint in any ordinary manner, and these glasses 15 16 coincide with each other.

In the bottom of the water-tank I insert a draw-off pipe, 18, upon which I secure the faucet 6, by which I draw off the water in this tank.

In the funnels 8 I place the removable or stationary strainers 19, through which the milk can be strained into the milk-cans. These funnels are secured to the bottom of the ice and waterpan, and when I remove this pan they come with it. In the bottom of this re frigeratingpan I locate suitable pipes, 20, to conduct the cold water down around the exterior of the milk-chambers or about the tank, and these pipes 20 extend above the bottom of the pan, so as to insure a certain depth of cold water thereon when desired.

21 is the general ventilating-shaft, and 22 is a draw-off pipe from the ice or Water pan.

I am aware that cylindrical milk-cans having in one side a vertical recess extending about twothirds the way up from the bottom, and having inclined and converging sides to the recess and a rounded back and. an upwardly-inclined top, have been heretofore invented and patented; but that is not my invention.
