Improvements in or relating to Washing Drums.
I, ROBERT SCHINDLER, Mechanical Engineer, of Lucerne, Switzerland,
do hereby declare the nature of this invention to be as follows :-
My invention relates to washing-drums.
The washing-drums hitherto in use, with perforated pipes on their interior
periphery, have had those pipes closed with covers rotating with the machine and
fixed at the ends, so as to half close the perforated pipes. Thereby a very
imperfect distribution of the water was obtained, and as the pipes always remained
half-open even during their upward motion, the fluid could easily flow out of them
again at their ends.
The washing drum constructed according to my invention, provides a remedy for
these inconveniences.
In it are arranged lengthwise at very close intervals or closely continuous, large
peripheral pipes perforated longitudinally on the inner surface. These pipes are
open at both ends; but a fixed incomplete ring spring-controlled, closes each end
being opposite and pressed against it from the time it attains the surface of the
wash-water on rising until it returns, for the next dip, in the course of its rotation,
so that the said water can freely enter the pipes so long as they are submerged.
Thus, at each rotation of the drum, the pipes are refilled just before they reach
the lowest point in their rotation, with the suds or other liquid employed in
washing. When the pipes begin to ascend their ends come opposite the ring which
closes them just before they emerge and prevents the wash-water from flowing out
otherwise than through the proper perforations, while thereafter during the
remaining part of their revolution, the water flows out in spray-jets upon the
contents of the drum, which are to be washed with a maximum discharge from
each pipe at the top of the drum.
By this arrangement the articles in the drum are inundated continually with
large quantities of fresh liquid in a manner and with an efficiency unattainable
even with pumps. As a special advantage must be mentioned the extreme cou-
venience of the process. The pipes may be perforated on their internal surface
throughout their entire length and breadth.
Dated this Second day of January 1895.

Improvements in or relating to Washing Drums.
I, ROBERT SCHINDLER, Mechanical Engineer, of Lucerne, Switzerland,
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:-
My invention relates to washing-drums.
The washing drums hitherto in use. with perforated pipes on their interior

page_text: periphery, have had those pipes closed with covers rotating with the machine and
fixed at the ends, so as to half close the perforated pipes. Thereby a very
imperfect distribution of the water was obtained and, as the pipes always remained
half-open, even during their upward motion the fluid could easily flow out of them
again at their ends.
The washing drum, constructed according to my invention provides a remedy for
these inconveniences, and is illustrated in the accompanying drawings, wherein
Figure 1 is a longitudinal section; and
Figure 2 a view partially in end elevation and partially in cross section.
In it are arranged lengthwise, at very close intervals or closely continuous, large
peripheral pipes a perforated as at a¹ ou the inner surface. These pipes
a are open
at both ends, and carried by the rotary discs a² but a fixed incomplete ring b
spring-controlled, closes each end by being opposite and pressed against it from the
time it attains the surface of the wash-water on rising until it returns, for the dext
dip, in the course of its rotation, inside the outer case c, so that the said water can
freely enter the pipes so long as they are submerged.
Thus, at each rotation of the drum, the pipes are refilled, just before they reach
the lowest point in their rotation, with the suds or other liquid employed in
washing. When the pipes begin to ascend their ends come opposite the ring b
which closes them just before they emerge and prevents the wash-water from
flowing out otherwise than through the proper perforations a¹, while, thereafter,
during the remaining part of their revolution, the water flows out in spray-jets
from the said perforations upon the contents of the dram, which are to be washed,
with a maximum discharge from each pipe at the top of the drum.
By this arrangement the articles in the drum are inundated continually with
large quantities of fresh liquid in a manner and with an efficiency unattainable
even with pumps. As a special advantage must be mentioned the extreme con-
venience of the process. The pipes may be perforated on their internal surface
throughout their entire length and breadth.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A washing drum with perforated peripheral pipes, characterised by the
pipes a being perfectly open at both ends of the drum, and, during their rotation
at their lowest point, taking in the wash-liquor freely and in large quantities while
as the rotary movement continues the running away of the liquor is prevented by
the closure of the pipe euds by means of the fixed ring or partial-ring
2. The combination and arrangement of parts constituting a complete washing
drum substantially as and for the purpose described and illustrated in the accom-
panying drawings.
