COMPLETE SPECIFICATION.
Improvements in Machines for Washing Fabrics.
1, CONRAD BLASCHKA, a partner in the firm of T. Schmitt, of Böhmisch Aicha,
in the Province of Bohemia and also of Vienna, in the Empire of Austria Manu-
facturer of Woollen Goods 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 :-
The time required for washing fabrics or piece goods by the machines heretofore
in use depends on the number of squeezings to which the fabric is subjected by the
wringing rollers and upon the number of times the fabric is passed through the
washing trough.
This invention has for its object to diminish the time required, by subjecting
the fabric, before passing through the wringing rollers, to the action of a ribbed
plate and of one or more smooth or fluted rollers, the plate or the rollers, or both,
receiving reciprocating motion relatively to one another by virtue of which the
roller or rollers will be caused to roll upon and strike against the ribs of the
plate, thereby causing the fabric to dry rapidly.
In the accompanying drawings, forming part of this Specification,
Figures 1 and 2 are vertical cross and longitudinal sections respectively
illustrating a washing machine embodying this invention;
Figures 3 and 4 represent two modified forms of the ribbed plate.
As shewn in Figures 1 and 2, the machine comprises a washing trough S
containing the liquid above which is arranged the ribbed plate P whereon rests
the smooth or fluted roller k made of suitable material, for instance of wood, the
said roller receiving to and fro motion from the driving shaft through the medium
of the crank and the connecting rod y whereby it is caused to roll upon the
plate.
The ends of the piece of fabric are sewn together so as to form an endless
band which passes over the roller into and through the washing trough S
wherein it runs beneath the rollers and h, thence over the roller and
between the ribbed plate P and the roller k the reciprocating motion of the
latter producing the result herein before described.
The fabric then passes around the rollers and m and between one or more
pairs of squeezing or wringing rollers a b, arranged behind the plate P, and over
the trough S, whereby the fabric is cleansed from the dirt dissolved by the
washing liquid.
The fabric then passes over the winged feed roller c by which it is deposited in
the funnel of the receiver T whence on emerging therefrom it passes round the
rollers d and e against the tension bar and over roller into the washing trough S,
and again follows the same course through the machine.
The liquid is heated by means of a steam pipe r traversing the lower part of the
trough S whilst perforated pipes p and o extending across the fabric and located
one at the point where the fabric is drawn in between the plate P and the roller k
and the other in front of the wringing rollers, deliver the water required for rinsing
on to the fabric.
As shewn in Figures and 4, the plate B, instead of being flat, may be curved
concavely or convexly and may be mounted on a rock shaft concentric with the
curvature of the plate which may thus receive reciprocating motion whilst the
roller is stationary.
Or both plate and roller may have reciprocating motions in opposite directions;
moreover, the plate may be arranged either above or beneath the roller. Finally,

page_text: instead of a single roller, several rollers having simultaneous motions may be
-employed.
It will be understood that a series of several similar washing apparatus consisting
of the trough S of the plate P and the roller k may be arranged one behind the
other in the same machine.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1. The combination, in a machine for washing fabrics such as described, of a
ribbed plate P and of one or more smooth or fluted rollers k the plate or the roller
or rollers, or both, having to and fro motion, and the fabric being drawn between
them so that it will be cleansed by being pressed against the ribs by the roller,
substantially as described and shewn.
2. In a machine for washing fabrics the ribbed plate and one or more smooth or
fluted rollers rolling thereon as described, in combination with a washing trough S
containing the liquid through which the fabric is made to travel before reaching
the said plate and roller, substantially as described and shewn.
3. In a machine for washing fabrics, the ribbed plate and one or more smooth or
fluted rollers rolling thereon as described, in combination with a squeezing or
wringing device a b by which the fabric is submitted to pressure whereby to cleanse
it from the dirt dissolved by the washing, substantially as described and shewn.
