UNITED STATES PATENT OFFICE.
ORIN LEONARD, OF BELVIDERE, ILLINOIS.
MILK-COOLER.
SPECIFICATION forming part of Letters Patent No. 471,646, dated March 29, 1892.
I Application 'led July 6, 1891. Serial No. 398,613. (No model.)
T0 all whom t may concern:
Beit known that I, ORIN LEONARD, a citizen of the United-States, residing at Belvidere, county of Boone, and State of Illinois, have invented certain new and useful Improvement-s in Cream-Coolers, of which the following is a specification.
The object of my' invention is to rapidly 'cool cream after it comes from the separators l in order to place it in condition for churning. This'result I accomplish by allowing the cream to run in athin sheet over a considerable surface of sheet met-al in the form of a receptacle, which is cooled by filling with ice or allowing `a stream of cold water to run through it.
In the accompanying drawings, Figure l is a perspective view of my cream-cooler as seen from the rear. Fig. 2 is also a perspective view of my cooler, showing a front View of Fig. 3 is a longitudinal vertical section of my cooler.
In the construction of my improved creamcooler I build of sheet metal a receptacle, the ends or heads 1 and 2 of which are of elliptical form. Between these two elliptical heads I place a side wall 3, also of sheet metal and corrugated to present to the cream a greater cooling-surface than would be encountered if the walls were smooth or of a regular outline. This drum, it will be understood, must be made with water-tight joints, and this result I effect by soldering them securely. I mount my drum upon four legs 4 at any convenient height above the floor. In the forward end of this water-tight drum I cut an opening 'and solder into it the tube 6, through which I have access to the inside of the drum, and which tube is closed at its upper end by the cover 7.
Directly below the opening 5 in the forward head of my drum I insert the pipe S, and in the opposite head 2 and near the upper part of the drum I place a like pipe 9, both of which pipes communicate with the inside of the receptacle. Y
The walls of my improved receptacle do not at any point come to the Vedge of the heads, but are set back, leaving the edge of the heads to project outward some little distance beyond the walls, the object of which will be hereinafter explained.
From the upper edge of each of the heads of my drum projects an ear l0, entering a loop l1 on each end of a trough 12, thereby holding the trough in .position -above thev water-tight drum. The length of the trough is such that it just fits between the two heads, and in its bottom are two series of perforations 13. A
Directly below the drum' and extending with its length is a trough 14, supported upon brackets 15, slanting toward the rear of the cooler and projecting some little distance beyond the legs, which trough catches the cream after it has passed over the cooling-surface of the drum.
Now having fully described the construction of my improved cream-cooler, I proceed to give the method of using it, which is as follows: If ice is to be used to cool the cream, I break it into small pieces and till the drum of the cooler through the tube 6 with the ice so broken and close the pipes 8 and 9 with caps, as shown in Fig. 3. Then allowing the cream to run into the trough 12, it feeds onto the walls of the drum through the series of perforations 13 in the trough-bottom, spreading the cream in a thin sheet over the outer surface of the walls of the drum,which have been made extremely cold by the ice within. The walls, being corrugated, present a large cooling-surface 'to the cream, and by the time it drops from the bottom of the drum into the inclined trough 14 it is at a low temperature. From this trough the cream may run directly into the vats, where it remains until ready for the churning process. When cold water is to be used to cool the cream, connection with the supply is made tothe interior of the drum through the pipe 8, and as the water absorbs heat from the cream and is thereby rendered .Warm it rises and escapes through the pipe 9 in or ends tightly secured to the side Walls and projecting beyond the latter to conne the cream to the surface of the side Walls, a pipe near the bottom of the receptacle for admitting cold Water, a pipe near its top for the escape of the Water, providing a circulation through the receptacle, an opening to the :interior of the receptacle, a spout leading from the opening toa point above the receptacle, a cover for the upper end of said spout, brackets on the receptacle, a perforated feedingtrough supported above the receptacle on the brackets, feet for supporting the receptacle above the loor, and a receiving-trough below the receptacle for collecting the cooled cream, 15 said trough supported on brackets between the supporting-feet.
GRIN LEONARD.
