We, JAMES LISTER of Prospect Mills, York Road, Worsted Spinner and THOMAS
BROWN of Prospect Mills, York Road, Combing Overlooker, both of Leeds in the
County of York 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 :-
Our invention has reference to construction of such brushes as are used on the
"Noble" and other kindred combing machines, the object of such invention being
to construct them in such a manner that they may be more evenly worn at the
same time lasting much longer than brushes now in use.
Instead of one oblong or ordinary circular brush, we employ two circular
brushes, one larger than the other, the heel brush being smaller than the front
brush.
Both dabbing brushes, the bodies of which may be formed of metal or wood,
are attached to a wooden or metal back by a central bolt provided in each, the
back itself being attached to the vertical slide in the usual way.
By slackening the central bolts which secure the brushes to the back, such
brushes can be rotated and adjusted by the attendant to different positions as they
wear, thus the surface of the bristles presented to the material operated upon can
always be kept even and thus operate with greater regularity, both upon the
material and with regard to each other.
The beds are perforated with cylindrical holes into which the bristles are
inserted, instead of employing taper holes as hitherto, thereby the bristles are
held more compact and retain their position better.

means of central bolts e and f, the back d being attached to the slide a in the
usual way.
By slackening the central bolts e and f the brushes A and B can be rotated and
adjusted by the attendant to different positions as they wear, thus the surface of
the bristles g and h presented to the material operated upon can always be kept
even and thus operate with greater regularity, both upon the material and with
regard to each other.
The beds b and c are perforated with cylindrical holes i as shewn at Figs. 1
and 3 into which the bristles g and h are inserted instead of employing taper holes
as hitherto, thereby the bristles are. held, more compact and retain their position
better in combination with the assistance of the ordinary wire fastening.
As the brushes wear down and to bring them to the same position as when new,
we provide thin washers which we place when required between the brush and
the back, by such means we are enabled to use them until they become exceedingly
short in the bristle. By this means also since the small brush wears quicker than
the larger one we are enabled to keep both brushes level with each other on
the face.
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 :-
1st. The combination of circular dabbling brushes A and B and mode of applying
the same to "Nobles" and other kindred combing machines, substantially as
herein set forth.
2nd. The arrangement of perforating the bodies b and c with cylindrical holes i
for receiving the bristles g and h such bristles g and h being secured therein by
ordinary means, substantially as herein set forth.
