PROVISIONAL SPECIFICATION.
Improvements in the Top Condenser Strippers of Carding Engines.
We, JOHN GEORGE BAMFORTII and WILLIAM HENRY BAMFORTH, Junior,
of the Firm of William Henry Bamforth's Sons of Road Side, Slaithwaite near
Huddersfield, Yorkshire, Emery Roller Coverers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the top condenser "strippers" of carding machines
which are employed to strip or remove the web or slivers of fibre from the
bottom condenser strippers and deliver same to the condenser rubbers.
Hitherto both of said strippers have been covered with fine wire cards or teeth
and the lower stripper, owing to the action of the rings or spaces on the ring doffer,
has been unequally worn or has had ridges formed thereon which have caused
portions of the web or slivers to be carried around by the top stripper instead of
being delivered to the condenser rubbers whereby the ends or fibre have or has been
broken or otherwise damaged.
Our invention is intended to obviate these evils and this we accomplish by
providing a glass covered roller in lieu of the present top stripper. The glass is
preferably ground or powdered and laid or built up on the periphery of the roller
in a layer or succession of layers secured with cement. The roller may first be
covered with suitable fabric onto which to bed the glass, or the said glass may be
secured to the fabric before the latter is attached to the roller. We may combine
with the ground glass a suitable proportion of emery, pumice stone, or sand, or any
suitable combination of said substances.
By covering the upper stripper with glass as described, the bottom stripper is
worn more equally over its periphery and the formation of ridges or inequalities of
working surface is prevented. The glass being smooth, no grinding action takes
place to injure or destroy the points of the wire teeth on the bottom stripper, but it
has sufficient biting power or roughness as to be well adapted to lay hold of the web
or slivers and transfer same from the bottom stripper to the condenser rubbers and
thereby perform the same functions as the ordinary card covered stripper.
The said rollers will wear a considerably longer time than the ordinary top stripper
and can easily be re-covered.

Improvements in the Top Condenser Strippers of Carding Engines.
We, JOHN GEORGE BAMFORTH and WILLIAM HENRY BAMFORTH, Junior,
of the Firm of William Henry Bamforth's Sons, of Road Side, Slaithwaite, near
Huddersfield, Yorkshire, Emery Roller Coverers, 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 top condeuser strippers of carding machines which

page_text: are employed to strip or remove the web or slivers of fibre from the bottom
condenser strippers and deliver same to the condenser rubbers. Hitherto both of
said strippers have been covered with fine wire cards or teeth, and the bottom
stripper, owing to the action thereon of the rings or spaces on the ring doffer, has
been unequally worn or has had ridges formed on the surface which have caused
portions of the web or slivers to be carried around by the top stripper instead of
being delivered to the condenser rubbers, whereby the ends or fibre have or has
been broken or otherwise damaged.
Our invention is intended to obviate the evils named and this we accomplish by
providing a glass covered roller in lieu of the present card clothed top stripper.
In the accompanying drawings A represents the ring doffer, B the top and C the
bottom condenser strippers, D the dividing roller and E the condenser rubbers, all
arranged as ordinarily.
In carrying our invention into effect we first cover the surface or periphery of
the roller intended for the top condenser stripper with canvas, cotton or other
suitable fabric to form a bed or foundation onto which the glass can be glued or
cemented with better results than on a bare roller. The glass we use is ground
or pulverized to the degree of fineness desired and is sprinkled or laid over the
whole surface of the roller and glued or cemented thereon with liquid gelatine or
with other suitable adhesive substance or cement. When a thin layer of ground
glass has been thus sprinkled or laid over the roller, it is rolled true and allowed to
cool or set before sprinkling another layer of ground glass over it. The ground
glass is built up to the requisite thickness in layers each applied as above set forth,
each layer being rolled and the gelatine, glue or cement allowed to dry or set before
a subsequent layer is sprinkled over it.
The above method of applying the ground glass and securing it on the roller with
gelatine we find to answer very well, but it is obvious that some little variation may
be made without departing from our invention, as, for instance, the ground glass
may be built up to the required thickness on a piece of canvas or other fabric and
the latter afterwards secured to the roller, considerable care being, however,
necessary to obtain a true and level surface.
To the ground glass may be added where required, a suitable proportion of
emery, pumice stone, sand or like gritty substances, or combinations thereof.
By covering the top condenser stripper B with glass as described, the bottom
stripper C is worn more equally over its periphery and the formation of ridges or
inequalities of working surface is prevented. The glass being smooth, no grinding
action takes place such as would injure or destroy the points of the teeth, but it
tends to maintain the points of the teeth for a longer time and has sufficient biting
power or roughness as to be well adapted to lay hold of the web or slivers and
transfer same from the bottom stripper to the condenser rubbers and thereby
performs the same functions as the ordinary card covered stripper.
The said glass covered rollers will wear considerably longer than the ordinary
top strippers and can easily be re-covered.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The application to the top condenser strippers of carding machines, of a coating
or covering of ground or fine broken glass to which may be added emery, sand and
like substances, in manner and for purposes substantially as herein described.
