PROVISIONAL SPECIFICATION.
Improvements in Rollers for Drawing and Spinning Machinery.
I, ARTHUR HARRY BRIGGS, of Briggella Mills, Bradford, in the County of
York, Spinner and Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to certain improvements in the construction of top rollers.
for drawing and spinning fibres into yarn, whereby better results are obtained in
the quality of the yarn, and less power is required to drive the frames than
hitherto.
Top rollers as hitherto constructed are made of wood or iron with an outer
covering of leather, the whole mounted upon a centre which centre is held in
journals by spiral springs subjected to pressure by thumb screws, in order to bring
pressure of the rollers upon the bottom rollers which are composed of iron, and
thereby effect an even draught or drawing out of the fibre.
The object of covering the rollers with leather is to obtain an outer surface of.
even elasticity throughout. This is rarely obtained when wood or iron rollers are
covered with leather.
"7
The fibre passing between the top leather covered roller. and the bottom iron
roller, subjected to the pressure already described, in a very short time either cuts
through the epidermis of the covering or forms a groove in the same and renders.
the leather covered roller useless, the roller must then be replaced by a newly
covered roller.
In order to remedy the above defects, amongst others, and to accomplish the
object of this my improvement, I construct an ordinary metal centre or spindle and
secure upon the same a boss of suitable size of wood or other material on the top.
of which I fit a circular india rubber or other elastic buffer, on the top of this
circular buffer I secure by ordinary means a leather covering.
1
The roller is then ready for use, by its construction less pressure is required
upon the roller, and with the lighter pressure a greater nip or hold upon the fibre
is obtained when passing between the top and bottom rollers in the operation of
drawing and spinning.
This reduction of pressure upon the rollers involves a material reduction in the
power required to drive the same.
Another advantage is obtained in the longer life of rollers when constructed
according to my improvement, as the buffer between the boss and the leather
covering yields to the varying thicknesses of the fibre passing between the rollers,
thus preventing the cutting of the epidermis of the leather and the formation of
grooves in the same, and thus keeping the rollers longer in use.
Dated this 11th day of December 1895.

I, ARTHUR HARRY BRIGGS, of Briggella Mills, Bradford, in the County of
York, Spinner and 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 certain improvements in the construction of what are
known as the top rollers for drawing and spinning fibres into yarn, whereby better
results are obtained in the quality of the yarn, and less power is required to drive
the frames than hitherto.
Top rollers as hitherto constructed are made of wood or iron with an outer
covering of leather, the whole mounted upon a centre, which centre is held in
journals by spiral springs subjected to pressure by thumb screws, in order to bring
pressure of the rollers upon the bottom rollers, which are composed of iron, and
thereby effect an even draught or drawing out of the fibre.
The object of covering the top rollers with leather is to obtain an outer surface
of even elasticity throughout. This is rarely obtained when wood or iron rollers
are covered with leather.
The fibre passing between the top leather covered roller and the bottom iron
roller, subjected to the pressure already described, in a very short time either cuts
through the epidermis of the covering or forms a groove in the same and renders
the leather covered roller useless, the roller must then be replaced by a newly
covered roller.
In the accompanying drawing
Fig. 1 represents an end view of a roller covered in accordance with my
invention, and
Fig. 2 is a section through same.
In order to remedy the above defects, amongst others, and to accomplish the
object of this my improvement, I construct an ordinary metal centre or spindle A.
and secure upon the same a boss B. of suitable size, of wood, or other material,
on the top of which I fit a circular india rubber or other elastic buffer C, and
on the top of this circular buffer C. I secure by ordinary means a leather
covering D.
The roller is then ready for use, by its construction less
upon the roller, and with the lighter pressure a greater "nip
pressure is required
or hold upon the
fibre is obtained when passing between the top and bottom rollers in the operation
of drawing and spinning.
This reduction of pressure upon the rollers involves a material reduction in the
power required to drive the same.
Another advantage is obtained in the longer life of rollers when constructed
according to my improvement, as the buffer C. between the boss B. and leather
covering D. yields to the varying thicknesses of the fibre passing between the
rollers, thus preventing the cutting of the epidermis of the leather covering D.
and the formation of grooves in the same, and thus keeping the rollers longer
in use.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
The construction of drawing out and spinning rollers composed of a enindle A

page_text: upon which is secured a boss B. of wood or other material and upon which is
mounted a concentric ring of india rubber or other elastic substance C. with a
covering of leather D, substantially in the manner and for the purpose herein-
before set forth.
