We, WILLIAM DEWAR of Strathmartine, Forfarshire, Implement Maker and
WILLIAM BRUCE MAIR of Rosemount Cottage, Dundee Forfarshire, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in washing machines and the apparatus
consists of two side cheeks or frames in which are carried the axes of two roller
brushes. The bearings of one or both brushes are situated in horizontal slots in the
frames and they are acted upon by spiral or other springs in such a way that whilst
the circumferences of the brushes are maintained close together they are still able to
yield or move from each other according to the thickness or number of folds of the
fabric passed between them. The side frames are secured in or constitute part of a
tub or receptacle containing water to a depth which extends above the axes of the
brushes and in the upper parts of the frames immediately above where the brushes
approximate closest to each other there are carried two guiding or feeding rollers
preferably covered with india-rubber or other elastic or yielding material these rollers
being also kept close to each other by means of spiral or other springs acting on the
bearings of one of them. The tension or pressure of the springs acting on the feed
rollers and also of the springs acting on the brush roller or rollers is regulated by
pinching screws or equivalent means. Above the feed rollers and extending from one
frame to the other there is preferably provided in the machine an inclined board over
which the fabric to be washed is led to the feeding rollers and from thence it is fed to
the brush rollers by which it is acted upon on both sides and thoroughly cleansed the
apparatus being finally delivered into the bottom of the tub or receptacle and from
thence removed by hand.
The several rollers are rotated in the proper directions relatively with each other
by a crank, hand wheel or its equivalent placed on an end of the axis of one of the
brush rollers a spur wheel being situated on the other end of the said axis and geared
with a corresponding wheel on the axis of the other brush roller. On the driving

page_text: axis there is also keyed a spur pinion which is geared with a wheel on the axis of
one of the feeding rollers the other feeding roller being driven by friction.
To clear the brush rollers there are provided a series of heckle pins fixed in bars
extending from one side frame to the other, the heckle bar for one roller being
preferably above and that for the other roller below the axis.
In lieu of fixing the side frames in or forming them on the tub or receptacle the
apparatus hereinbefore described may be made removable from the tub in which case
the frames are provided with means for securing them in a tub when the apparatus is
to be employed.

page_text: Improvements in Washing Machines.
We, WILLIAM DEWAR of Strathmartine, Forfarshire, Implement Maker and
WILLIAM BRUCE MAIR of Rosemount Cottage Dundee, Forfarshire, Engineer 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:-
This invention relates to improvements in washing machines and as seen in cross
section at figure 1 and in end elevation at figure 2 of the accompanying drawings the
improved apparatus consists of two side cheeks or frames A in which are carried the
axes of two roller brushes B C. The bearings of the brush B are situated in
horizontal slots D in the frames A and they are acted upon by spiral or other springs E,
in such a way that whilst the circumferences of the brushes are maintained close
together they are still able to yield or move from each other according to the
thickness or number of folds of the fabric passed between them. The side
frames A are secured in or constitute part of a tub or receptacle F containing water
to such a depth as will cover the axes of the brushes B C, and in the upper parts of
the frames immediately above where the brushes approximate closest to each other
there are carried two guiding or feeding rollers G H preferably covered with india-
rubber or other elastic or yielding material these rollers being also kept close to
each other by means of spiral or other springs I acting on the bearings of one of
them. The tension or pressure of the springs 1 acting on the feed roller H and
also of the springs E acting on the brush roller B is regulated by pinching screws J
or equivalent means. Above the feed rollers and extending from one frame to the
other there is preferably provided in the machine an inclined board K over which the
fabric to be washed is fed to the said rollers from whence it is passed to the brush
rollers B. C. by which it is acted upon on both sides and thoroughly cleansed the
fabric being finally delivered into the bottom of the tub or receptacle F and from
thence removed by hand.
I
The several rollers are rotated in the proper directions relatively with each
other by a crank, hand wheel, or its equivalent placed on an end of the axis of
the brush roller (a spur wheel L being situated on the other end of the said axis
and geared through the wheels M N figure 2 with a corresponding wheel O on the
axis of the other brush roller. On the said axis there is also keyed a spur pinion P
geared with a wheel on the axis of the feeding roller G, the other feeding roller
being driven by friction, or instead of driving the roller G the roller H may be
driven from a spur wheel situated on an intermediate shaft and by connecting the
crank to the said intermediate shaft and driving the brush roller C from another
wheel upon it the machine may be geared up to any desired speed.
To clear the brush rollers a comb R is provided in conjunction with each of them,
the said combs preventing the cloth wrapping round the rollers.

page_text: In lieu of fixing the side frames A in or forming them on the tub or receptacle
the apparatus hereinbefore described may be made removable from the tub in which
case the frames are provided with means for securing the apparatus in position when
it is to be employed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The general arrangement and combination of parts constituting the improved
washing machine herein before described with reference to the drawings annexed.
2. In a washing machine the employment of two brush rollers substantially as
described with reference to the accompanying drawings.
3. In a washing machine the combination of two brush rollers and two feeding
rollers substantially as described with reference to the appended drawings.
