MILK-GAN-STEAMING AND WATER-HEATING SYSTEM.

Application filed July 10, 1925.

My invention pertains to a milk can steaming and water heatin system, and 1S specially designed for use in creameries in connection with various operations calling for the use of steam and hot water. Chief among those is the cleansing of cans in. which milk or cream has been delivered to the creamery, a novel and eiiicient means being provided in the invention for performin this operation.

Another object of the invention is to provide a supply of water of a temperature suitable for making tests in connection with the receipt of large quantities of cream, and another supply of water 01"- a varying bath temperature.

Another purpose of the invention 13 the provision of a combined steam producing and water heating system, having a common burner or heating element, the steam and hot water produced thereby being used for the above named purposes.

Another object thereof is to provide a supply of water of moderately warm temperature, to be used in common for the several purposes hereinbefore named.

The above named, andother features and advantages of the invention will more fully app-ear from the following specification, reference being had to the accompanymg drawings, in which Fig. 1 shows the invention in elevation, with the casing 6 in section.

Fig. 2 is a plan view thereof.

Fig. 3 shows the boiler 8 in vertical medial section.

Fig. 1 is a detailed view of the top plate 27 ot the casing 6.

Fig. 5 is a similar view of the bottom plate 29 thereof.

The reference number 1 indicates a frame, preferably formed of tubing, in the upper part of which is supported a tank 2. Fixed to the upper part of said frame is a. dishshaped support 8, provided with lugs a, to receive the rim of an inverted cream-can 5, and hold the same in such position. Beneath the tank 2 is a cylindrical shaped casing 6, in the lower part of which is a burner 7, for gas or other combustible material. Immediately above the burner 7 is a boiler 8, from which apipe 9 projects upwardly to a point above the support 3, and within the mouth of a can, when one is supported thereon. Said pipe is held in place by a collar 10, fixed thereto, and bearing against Serial No. 42,836.

the support 3, and the lower end of said pipe is connected with the boiler 8 by means of a plug 11, tapped into the upper part of the boiler.

Comn'iunicating with the tank 2 through the bottom thereof is a pipe 12, with which is connected a coil 18, winding about the boiler 8. Projected downwardly from the lower part of said coil is a. pipe 14, loopedoutwardly into a pipe 15, from which a pipe 16 enters the boiler 8. A supply 01"" water from the tank 2 is thus permitted to enter the boiler. From the upper part of the coil 13 a connection is made through a pipe 17. with the tank 2, aiding a circulation of water in said tank and through the system of pipes connected therewith. This is further enhanced by means of a pipe 18 connecting the pipes 12 and 17.

The upper part of the coil 13 terminates in branch pipes 19, connected with a small pair of tanks or pans 20 and 21, each of the pipes 19 being provided with handvalves 22, as shown with one of said pipes in Fig. 1.

The admission of a. supply of water to the boiler 8 may be controlled by means of a valve in the pipe 16, as shown at 23, said valve being connected with an operators rod 24, held in braces at the side of the frame 1. The boiler 8 is'provided with a number of vertical flues 26, through which the heat passes from the burner 7, when the same is in operation. Upon a supply of water being admitted to the boiler, it is converted instantly into steam, which finds its way upwardly through the pi pc 9, to the interior of the can 5, thoroughly cleansing and sterilizing the same. The can is then removed, and another one placed in position, whereupon the operation is repeated.

Thetop plate 27 of the casing 6is provided with a central opening 28, forming a space about the pipe 9, and the bottom plate 29 has several openings 30, which permit entry of air to the casing, a circulation of the air upwardly being provided for by the opening 28, the heated air passing through the opening 28 striking against the bottom of the tank 2, and assisting in heating the water therein. The temperature of this water is further raised by reason of the heated water in the coil entering the same through the pipe 17. The water in said tank is thereby always maintained at a temperature which will enable it to be quickly converted into steam, or raised to a still higher temperature for use in tests as mentioned.

Connected with the lower part of the boiler 8 is adrain-pipe 31, provided with a shut-ott' cock at its end, and at the lower end of the pipe is a drain-cock 32, by opening which the entire system may be drained.

By manipulation of the Valves 22 water may be permitted to enter the pans and 21, and attain different temperatures therein.

Assuming the pan 20 to be designed for a hot bath, in practice the temperature of the water therein would range from to l lt) degrees, while the pan 21, it intended for testpurposes, would contain a supply of water of from to degrees.

It will be observed that the machine is simple and compact in form, and convenient for the purposes for which it is intended.

lVha-t I claim, and desire to secure by Letters Patent, is:

A device of the class described, comprising a frame, a heater casing in the lower part off said frame, and heater therein, a boiler in said casing adapted to receive heat from said heater, a discharge pipe leading i'rom said boiler, a water supply tank and pipe system between said tank and boiler, a coil encircling said boiler and communicating with said pipe stem at the upper and lower ends oi said coil, and a water chamber in proximity to said tank and coinmunicating with said coil.

In testimony whereof I aflix my signature.

HAROLD F. BER G.
