DEVICE FR'CLEANING BEER-PIPES.

SPECIFICATION forming part of Letters Patent No. 718,502, dated January 13, 1903. Application filed J'uly 17. 1902. Serial Nor 115,959. (No model.)

T0 a/ZZ whom, it may concern:

Beit known that I, AUGUST MLLER, a citizen of the United States, residing at Bridge.- port, county of Fairfield, State of Connecticut, have invented a new and useful Device for Cleaning Beer-Pipes, of which the following is a specification.

My invention has for its object to provide a simple and inexpensive device that will act to thoroughly and quickly cleanse beer-pipes and other stationary pipes that are liable to become foul in use.

Heretofore cleansing solutions have frequently been forced or drawn through beerpipes and other pipes by means of pumps. It is of course well understood thatbeer is ordinarily drawn through pipes made of solid tin and that the quality of the beer as drawn depends greatly upon the condition in which the pipes are kept. Where large quantities of beer are drawn, the 'pipes do not as quickly become foul, and large drawers are, furthermore, usually provided with efficient, thoughV usually complicated and expensive, means for cleaning pipes.

My present invention is adapted for use by both large and small drawers of beer and by any users of pipes liable to become foul in use, and is especially adapted for use by the large number of small beer-drawers who have not heretofore been provided with ecient means for cleaning pipes, the sole requirement for the use of my invention being a How of water, as from a city water-pipe or a pip from a spring.

lVith the above ends in view my invention consists in the construction of the reservoir adapted to contain caustic potash, lye, or other detergent material, either loose or in its original receptacle, substantially as hereinafter described and claimed, said reservoir being provided at each end with a threaded vhub to receive a connection either to a watersupply or to a beer-pipe.

In theaccompanyingdrawings,forming part of this specification, Figure 1 is a sectional view illustrating my invention; Fig. 2, an inverted plan view of a holder for caustic potash, lye, orother detergents used in the form illustrated in Fig. 1.

A denotes the reservoir, which may be made have illustrated a form in which the reservoir consists of a cylinder either cast or drawn from heavy sheet metal, said cylinder being externally threadedv at each end to receive threaded caps or heads 10, packing 1l being interposed between the ends of the reservoir and the heads. Each end ot' the reservoir is provided with a threaded hub B for the attachment of a iiexible or other connection extending either to a water-pipe or a beer-pipe, it being of course understood that my novel cleaning device in use is interposed between a water-supply pipe (not shown) and a beerpipe (not shown) connections, (not shown,) which may of course be either flexible or rigid, being interposed between the hubs B and the water-supply pipe and the beer-pipe, respectively.

The device illustrated is intended to be used with loose detergent material, as caustic potash .or lye. For this reason a holder C is provided to receive the potash or other detergent material and prevent it from clogging the pipes. The holder consists, essentially, of a perforated diaphragm 15, a stem 16, extending therefrom, which may be either solid or a tube registering with a hole through the diaphragm, and a perforated disk 17, adapted to slide freely over the stem. In order to provide an ample water-chamber, which I have indicated by D, in the bottom of the reservoir, I provide the diaphragm 15 withV legs 18, adapted to engage the end of the reservoir, so that the diaphragm will be held above theplane of the lower hub B, and thus form a water-chamber.

19 indicates detergent material, as potash.

In use one head of the reservoir is removed, the disk removed `from the holder, and the latter dropped into the reservoir with the legs downward. Then the potash or other detergent material is poured in and the disk is placed over that, as in Fig. 1. In practice the reservoir is ordinarily not entirely filled with detergent material, so as to leave a chamber E above the disk. When stem 16 is a tube, as shown in the drawings, a certain amount of water will pass through the tube and will dissolve the potash in the upper end of the res- IOO ervoir should any get there, and thus render it impossible for the upper end of the reservoir or the beer-pipe to become clogged.

Having thus described my invention, I claiml. A device for cleaning pipes comprising a reservoir provided with inlet and outlet hubs, e disk having depending supportinglegs whereb7 a water-space is formed therebelow, said legs being of a length to support the disk above the plane of the lower hub, n stem carried by seid disk, and a second disk mounted to slide on said stem.

2. A device for Cleaning pipes comprising a reservoir provided with inlet and outlet hubs, a disk mounted in said reservoir and having supporting-legs and arranged to support detergent material, a Waterspaee being formed below seid disk, said legs being of e length to support the disk above the plane of the lower hub, a hollow stem formed integral with said disk, and a second disk mounted to slide ou said stem.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST MLLER.
