PATENT OFFIC PIPE-CLEANING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 528,234, dated October 30, 1894.

Application filed March 1, 1894. Serial No. 501,897- (No model.) 7

To all whom it may concern:

Be it known that we, ALBERT O. MUELLER and ADAM LIEB, citizens of the United States, and residents of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pipe-Cleansing Apparatus, of which the folafter more fully described and particularly.

set forth.

In the accompanying drawings, forming part of this specification in which like letters of reference designate corresponding parts throughout, Figure 1 is a vertical section through the center of our improved apparatus. Fig. 2 is a section of the same, taken on the line 0c--00.

In the practice of our invention, we construct a preferably square casing or housing A, within which are arranged one or more series of pipe coils a, corresponding in shape to the housing, the inner and middle coils, a a respectively, being connected together by a serpentine or S shaped pipe I). At one side of the housing which is supported upon legs A is the inlet or cold-water pipe 0 extending therethrough, and joining with the outer coil a this inlet pipe being connected to any suitable source of supply and controlled by a valve 0'. The end of the inner pipe coil a continues as the outlet or hot-water pipe 01 and passes through the wall of the housing opposite the cold-water pipe. These two pipes c and d serve to support the coils. The hot-water pipe 01 leads to the base of a tank or chamber B, located in proximity to the housing A. This tank has at both its top and bottom plates e e, the latter being perforated throughout its area. Intervening these plates is a cylindrical body 0 divided 0% by partitions f into cells f, f and f the body and the partitions both being perforated.

These cells are filled with lye, salt and soda Any suitable heating device may be in-v serted withinthe body A to heat the water in the coils a. We have here illustrated a pipe D having a rose D at the end, situated in the center of the body, beneath the coils, through which hot air is distributed. The water may, however, be heated directly by gas, oil, gasoline or other lamp, stove or furnace, or steam may be circulated in the body, the invention not being restricted in this particular.

The operationof the device will be readily apparent from the foregoing description takenin connection with the drawings. The cold water entering by the inlet pipe 0, flows through the three coils being thereby thoroughly heated, and passesby Way of the hot Water pipe (1 to the cylinder B, where it mixes with the materials in the cells. The water thus impregnated with the alkali escapes by the pipe g to the beer-pipes, in passing through which it completely cleanses and washes away all impurities from the interior thereof.

In order that the pipes may be rinsed and any trace of the alkali apt to injure or affect the taste of the beer or other liquors be removed, we connect the top of the chamber B, above the plate 6, to the hot water pipe (1 by means of a pipe h, each of the pipes being provided with a valve d and h. At the opposite side of the chamber B is a small elbow pipe t' leading to the outlet pipe g.- By closing the valve cl and opening the valve h the flow of the hot water may be directed to the beer-pipes without passing through, or communicating with, the cleansing material in the cells. v

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a pipe cleansing apparatus, the combination, with a suitable water heating device, of a mixing tank having a perforated body supported within the same, the said body comprising two or more cells, alkaline materials of a difierent character in each of the said cells, and suitable connections from the heater to the mixing tank and, from the latter to the pipes to be cleansed, substantially as shown and described.

2. In a pipe cleansing apparatus, the combination, with a suitable heating device, of a mixing tank having a perforated body supported Within the same adapted to receive alkaline material, the said tank connecting to the pipes to be cleansed, achamber atthe top of the tank apart from the body, and also conmeeting: with the pipes, and suitable connections from the heater to the tank and to the chamber, substantially as shown and described.

3. In a pipe cleansing apparatus, the combination, with a water heater, a mixing tank, and the connections to and from the same, and to the pipes to be cleansed, of a' perforated body supported in the said mixing tank, divided into cells, and a quantity of lye, salt and soda in the said cells, substantially as shown and described.

4. In a pipe cleansing apparatus, the combination with a mixing tank having a perforated body supported within the same adapted to receive alkaline material, the said tank connecting to the pipes to be cleansed, and a chamber at the top of the tank apart from the body, of a heater comprising a series of pipe coils arranged Within a housing, a cold Water pipe connecting with the beginning of the coils, a hot water pipe leading from the opposite end of the coils to the tank and connections from the said hot water pipe to the chamber at the top of the tank, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two witnesses, this 21st day of February, 1894.
