COMPLETE SPECIFICATION.
Improvements in Cleaning Metal Pipes, specially applicable
to Beer Pipes.
We, FRIEDRICH KRENTZ, Inventor and EMIL KRENTZ, Inventor, both of
116 Bleecker Street Jersey City Heights, in the County of Hudson, State of New
Jersey, United States of America, and MORGAN CHARLES SILSBEE, of Avoca,
in the County of Steuben, State of New York, United States of America,
Telegraph Operator, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
Our invention relates to cleaners for cleaning pipes, and more particularly to
that class of pipes, used in drawing beer or other liquids from vats or kegs, to
remove the slime and such foreign matter as may be deposited on the inside of the
pipe, which if left to remain is liable to clog up the pipes and render the beer
impure, thus lowering its quality.
Heretofore pipes have been cleaned by flushing with a solution of soda and
other chemicals, which was liable to give a foreign taste to, and injure the beer.
In the accompanying drawings :
Figure 1, is a longitudinal sectional view of a pipe showing the invention
inserted thereon.
Figure 2, is a perspective view of my improved
brush, showing the
brushes A and A', the rod or axle B, and the propeller C.
Similar letters refer to similar parts throughout the several views.
A and A' designate two brushes circular in form, and composed of any suitable
material, such as bristles splints or wire.
The brushes A and A₁ are placed at the opposite ends of rod or axle B, the
brush A to be secured firmly to the rod, while the other brush A' is secured to
the screw propeller C, and rotates with it on the axle B. The screw propeller is
situated between the two brushes and furnishes the motive power for revolving the
brush A' and forcing the invention through the pipe to be cleaned.
The screw propeller is acted upon, and revolved by the pressure of the water
passing through the blades of the propeller, while passing through the pipe,
which operation will be more fully explained hereinafter.
The operation of cleaning the pipe is as follows: One or more of my improved
brushes are inserted into the pipe E, the said brushes to fit snug inside of the
pipe, so as to come in close contact with the sides, then water is squirted from a
hose into the pipe to be cleaned, which is compelled to pass through the blades of
the screw propeller C, thereby causing them to revolve, and as the brush A' is
secured to one end of the propeller it revolves at the same time, and being in close
contact with the inside of the pipe to be cleaned, it scrapes and removes all slime
and sediment from the pipe.
The rotary motion given to the propeller by the pressure of the water passing
through the blades forces the device through the pipe, thereby causing the
stationary brush A to force out of the pipe all slime and other foreign substance
detached from the inside of the pipe by the rotary brush A'.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what w
claim is :
1. A pipe cleaner comprising a propeller having a brush secured to one end
thereof, and a brush upon the opposite end, revoluble independently thereof,
substantially as shown and described.
2. In a pipe-cleaner, the combination of a propeller, a rod or axle upon which
the propeller revolves, brushes situated at each end of the rod or axle, one of
which is securely attached to the propeller and revolving with it, and the other or
inner brush situated at the end of the rod opposite from the brush on the propeller
and rigidly connected to the rod, substantially as shown and described.
Dated this 25th day of February 1895.
