An Improved Washing and Rinsing Machine.
We JEAN RENSON of Dartmund and EMILE RENSON of Rambach near Wiesbaden
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:
A washing and rinsing machine according to this invention is shewn in the annexed
sheet of drawings. It consists of a drum A capable of being rotated backward and
forward and resting on trunnions in the fixed cylindrical container c.
The drum A serves to receive the linen to be washed which is introduced into it
through the opening d which is adapted to be closed by a cover.
The cylindrical container enclosing the drum A receives the lye required in
the washing through the opening E which is also adapted to be closed by
a cover.
As will be seen from Fig. 1 the drum A has in section a peculiar form bounded by
eight circular arcs of which four are curved inwardly and are perforated the other
four are rounded and are provided with blades or shovels f.
The inwardly curved perforated surfaces cause the linen to be raised to a sufficient
extent during the rotation of the drum A without being liable to slide down too
soon.
The blades serve to take up lye, whilst they are passing the lower part of the
container c, and to discharge the same through the perforated inwardly curved
surfaces upon the linen which would otherwise not be thoroughly moistened or
wetted as by the rotary motion of the drum A the lye would, without. the blades,
be thrown against the walls of the container c and thus not be able to enter the
drum A in sufficient quantity.
The drum A is rotated by means of the crank handle G and the toothed
wheels h and i.
The crank handle is turned alternately in opposite directions so as to impart an
alternating rotary motion to the drum; this has the effect of preventing the linen
from becoming twisted together.

page_text: In large power driven machines the alternating motion of the drum A is effected
by means of reversing gear.
It will be understood that the machine hereinbefore described may also be provided
with supply pipes for cold or warm water or steam.
By reason of the cylindrical form of the container, as also of the small intervening
space between the drum and the container, and of the form of the drum with its
blades, washing operations can be effected with the smallest possible quantity of lyc.
By this means washing may be carried on very cheaply.
After each washing operation the lye may be run off, so that the linen can be
rinsed at once in the machine.
The operation of washing is as follows:-
When the drum is rotated, the linen collects in one of the four angles of the
drum A, and on the rotation of the latter the linen will be lifted by the inwardly
curved perforated surfaces and then allowed to fall into the nearest lower
corner.
The lye is by this means effectually forced to pass through the material or fabric
of the linen, thereby loosening and removing the adhering dirt.
The linen which has its water squeezed out by this falling, is sufficiently moistened
each time by the action of the blades ff which are continually taking up the lye
and then discharging the same upon the linen.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. In a washing machine comprising a drum A having the section shewn in Fig. 1
of the annexed drawings working in a fixed casing b, the linen being introduced into
the drum A and the lye into the casing b. substantially as described.
2. In a machine of the kind referred to in the preceding claim, the arrangement of
blades ff, on the rounded angles of the drum A for the purpose of effecting a
continuous discharge of lye or water upon the linen to be washed or rinsed, sub-
stantially as described.
3. The improved washing and rinsing machine constructed, arranged and operating
substantially as described with reference to the drawings.
