I, JAMES STEAD of 11 Greenwich Street, Holbeck, Leeds, in the County of York,
Machine Maker, do hereby declare the nature of this invention to be as follows —
"
In cloth brushing machines as usually constructed, the cloth under treatment passes
over or partly around two revolving brushes, both of which rotate in such a direction
that they oppose the motion of the cloth. When fancy cloth such as Worsteds,"
"Tweeds," and such as have a ribbed surface are being treated, these brushes do not
thoroughly reach the rear or following sides or edges of the ridges, ribs or furrows.
Now my invention consists in so arranging one of the said brushes that it may be made
at will to rotate in a reverse direction to the other so that both sides or edges of
the ridges, ribs, furrows or sunk parts may become thoroughly acted upon by the two
brushes.
The reverse motion may be effected by any suitable mechanical device, but by
preference I drive the brush by a system of toothed gearing comprising four wheels,
one of which is on the brush shaft, two are intermediates in gear with each other,
one of them is always in gear with that on the brush shaft, and are mounted on a
swivelling lever by which they are capable of being brought alternately into gear with
the fourth wheel which is the first driver in the system, thus causing the brush to
rotate in either direction at pleasure.

page_text: I, JAMES STEAD, of 11, Greenwich Street Holbeck, Leeds in the County of York,
Machine Maker, 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 :-
In cloth brushing machines as usually constructed, the cloth under treatment passes
over and partly around two revolving brushes, both of which rotate in such a direction
that they oppose the motion of the cloth.
When fancy cloth such as "Worsteds," Tweeds, and such as have a ribbed surface
are being treated, these brushes do not thoroughly reach the rear or following sides or
edges of the ridges, ribs or furrows.
Now my invention consists in so arranging rotating brushes in a cloth brushing
machine that one of them may be made at will to rotate in a reverse direction to the
other, so that both sides or edges of the ridges, ribs, furrows or sunken parts of
material under treatment may be thoroughly acted upon by the brushes.
The reverse motion may be effected by any suitable mechanical device.
In the annexed illustrative drawings Fig. 1 is a side elevation of a cloth brushing
machine embodying my invention. Fig. 2, is a plan, a, is the framework, b, and c,
are two rotating brushes, the brush, is driven from any suitable motor by strap on
the fast, pulley e. d, is a loose pulley, f, is a pulley on the same shaft for imparting
motion to the usual shaft g, by a cross strap h, on pulley i; on the other end of the
shaft is a pulley j, from which the brush c is driven in either direction by open or
crossed strap as may be required; or the brush e, when required to rotate in the
same direction as the brush, may be driven direct therefrom as indicated in side
elevation by strap shown in dotted lines, but as the distance between the shaft and
the brush c is greater than from one brush to another, it is preferable to drive from
shaft g, the wear and tear of the straps being less.

treatment. Although I have described my invention as applied in a machine con-
structed with only two rotating brushes, it may evidently be adopted where more than
two brushes are used.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is
-
In a cloth brushing machine having two or more rotating brushes, causing one or
some of such brushes to rotate in a contrary direction to the other or others substan-
tially as and for the purpose specified.
