PROVISIONAL SPECIFICATION.
Improvements in or applicable to Stripping or Cleaning Brushes
for Carding Engines.
I JAMES ARROWSMITH of Bridgewater Works, Pendleton in the County of
Lancaster, Wire Card Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to the construction of the revolving stripping or cleaning
brushes employed for cleaning the surface of the card "flats" in carding engines,
the objects of the invention being to improve the operation of such stripping
brushes and to enable the same brush to clean the ends of the flats which work on
the "bend" of the engine as well as the surface of the card teeth.
In the first place I make the roller itself of wood with a raised rim about half,
an inch high at each end of such a form that when covered with a strip of card
clothing it will project beyond the body of the brush and clean the ends of the
"flats" which run on the bends,
The body of the roller which is between the raised rims I also cover with card
clothing having alternate strips of card teeth, and spaces without teeth, arranged
spirally preferably about four strips and four spaces to the circumference.
This spiral clothing may be put on in the form of narrow strips laid spirally side
by side, or it may be in the form of a sheet with slightly diagonal spaces and strips
of teeth alternating, but in either case the setting of the teeth will have to be in a
diagonal "echelon" form, each tooth slightly over-lapping the last so that when
the clothing is fixed spirally on the roller the crown of the teeth will be parallel to
the axis of the roller and at right angles to the direction of its work; at the same
time the warp of the cloth or foundation will be at right angles to the axis of the
roller.
The teeth of the brush will thus (although sot spirally) work accurately between
the rows of teeth across the flat.

COMPLETE SPECIFICATION.
Improvements in or applicable to Stripping or Oleaning Brushes
for Carding Engines.
I JAMES ARROWSMITH of Bridgewater Works Pendleton in the County of
Lancaster Wire Card Manufacturer, 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 the construction of revolving stripping or cleaning
brushes employed for cleaning the surface of the card "flats" in carding engines,
the objects of tho invention being to improve the operation of such stripping
brushes, and to enable the same brush to clean the ends of the "flats" which work
on the "bend" of the engine as well as the surface of the card teeth.
The nature of my said invention and the manner in which the same may be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of illustrative drawings and the following explanation
thereof.

page_text: Fig. 1 on the drawings is an elevation showing the two ends of a stripping brush
constructed according to my invention.
Fig. 2 is a transverse section,
Fig. 3 an end view of the same and
Fig. 4 is a view of part of one of the spiral strips or fillets drawn full size.
In the first place I make the roller a itself of wood with a raised rim b about
half an inch high at each end, of such a form that when covered with a strip of
card clothing (preferably with straight teeth as shown at Figs. 1 and 3) it will
project beyond the body of the brush and clean the ends of the "flat" which run
upon the "bends.".
The body of the roller a which is between the raised rims ǹ I also cover with
card clothing having alternate strips of card teeth c, and spaces without teeth,
arranged spirally preferably about three or four strips and the same number of
spaces to the circumference, three being shown on the drawing:
This spiral clothing may be put on in the form of narrow strips c laid spirally side
by side as shown, or it may be made in the form of a sheet with slightly diagonal
spaces and strips of teeth alternating, but in either case the setting of the teeth
will have to be in a diagonal "echelon" form, each tooth slightly overlapping the
last so that when the clothing or fillet is fixed spirally on the roller the crowns of
the teeth will be parallel to the axis of the roller, and at right angles to the
direction of its work, as will be seen plainly in the full size back view Fig. 4, at
the same time that the warp of the cloth or foundation as shown by the dotted
lines d will be at right angles to the axis of the roller.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
In stripping or cleaning brushes for carding engines
First. The combination on a wooden roller of alternate spiral strips or fillets of
card clothing laid on spirally with a raised rim also covered with card teeth
substantially as and for the purposes described and illustrated and
Secondly. The peculiar method of "setting" the strips or fillets of card teeth for
this purpose as hereinbefore described and illustrated by Fig. 4 of the drawings
annexed.
Dated this 30th day of March 1892.
