An Improved Covering for Rollers.
I, FRANK BARTLEET, of Badger Street, Bury, in the County of Lancaster,
Cork Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention is designed principally to be applied for covering rollers used
in machines for preparing and spinning cotton and other fibrous substances,
but it is also applicable for covering rollers used for mangling calendering and
other purposes.
The improved covering consists of a plastic composition formed from cork
which is granulated or powdered and mixed with glue, shellac, or other suitable
substance which is dissolved in hot water or spirit. The granulated or powdered
cork is then saturated therewith, spread out and allowed to dry gradually.
The roller to be covered is then placed in a suitable mould made of metal and
of sufficient strength to withstand a considerable pressure, the mould may be
polished inside and of such a diameter as to allow sufficient space between it and
the roller as will admit the required thickness of covering. The composition
made as above described is then rammed into this space until a sufficient density
has been obtained, after which it is submitted to hydraulic or other pressure
and it is then placed in an oven and baked in the mould.
The roller with its covering can then be removed from the mould and finished
and polished by turning in a lathe, after which it is varnished, and when dry
it is ready for use.
In some cases instead of forming the covering direct upon the roller as above
described I make a tube or sleeve of thin metal or other suitable material of
suitable size to fit the roller, and I cover the outside of this sleeve or tube with
the plastic composition in the manner described, and the tube can then be fitted
and fixed onto the roller by any suitable cement or adhesive material or com-
position.

I, FRANK BARTLEET, formerly of Badger Street, now of Hudcar Mill, Freetown,
Bury, in the County of Lancaster, Cork 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 is for a new or improved covering for rollers such as are

page_text: employed in machines for preparing and spinning cotton and other fibrous sub-
stances, and is also applicable for covering rollers used for mangling, and calen-
dering and for other like uses." In the accompanying drawing Eig. 1 is a side
view, and Fig. 2 a transverse section of a plain roller, Fig. 3 is a side view of
a fluted roller such as may be employed in textile machinery, either or both
of which may be formed by covering a metallic roller or a tube with my
improved covering in the manner hereinafter described. Figs. 4 and 5 illustrate
the means employed for applying my improved composition covering to a tube
or to a roller. In these views similar letters refer to similar parts.
According to this invention I obtain a plastic composition formed of granu-
lated or powdered cork that is mixed with either glue, shellac, or other suitable
adhesive substance which will dissolve in water or spirit and combine with the
cork that is saturated therewith. The mixture is then spread out and allowed
to dry gradually.
In order to cover a roller as e with the aforesaid composition, said roller is
placed on end centrally in a mould as of sufficient strength to resist hydraulic
or other pressure, the composition in a dry or nearly dry state is filled in the
space between the interior surface of the mould and the outer surface of the
tube or the roller, and when sufficient density has been, obtained by the applica
tion of hydraulic or other pressure, it is placed in an oven and baked in the
mould the roller with its covering can then be removed from the mould and
finished and polished by turning in a lathe after which it is varnished and when
dry it is ready for use. In the formation of a fluted roller as shown in Fig. 3
I prefer to employ a mould that is made of two, three, or more parts and clamped
together as shown in Fig. 5. The roller can be released from the mould after
being baked by disconnecting the parts of the mould and lifting the roller
therefrom instead of drawing said roller out at the end of the mould as may be
done with a plain roller. By these means the grooves in the roller may be
formed clean and sharp by the mould, and except in particular cases the roller
need not be machined and only require to be varnished.
In some cases instead of forming the covering direct upon the roller, I make
a tube or sleeve of thin metal or other material of suitable size to fit the roller,
and I cover the outside of said tube or sleeve with the plastic composition in
the manner hereinbefore described, the tube can then be fitted and fixed on
to the roller by cement or other adhesive material.
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:
. 1. Covering rollers such as are employed in machines for preparing and spin-
ning cotton and other fibrous substances, and rollers used for mangling and
calendering and other like uses, with a plastic composition that is obtained by
saturating. granulated or powdered cork with a soluble adhesive substance, the
saturated cork being then dried gradually and applied in a mould to the surface
of a roller by hydraulic or other pressure and afterwards baked in the mould
substantially as and for the purpose hereinbefore described.
2. A plastic composition for covering rollers that is obtained by saturating
granulated or powdered cork with a soluble adhesive substance, drying said
saturated cork gradually, applying in a mould under hydraulic or other pressure
and baking in the mould substantially as and for the purpose hereinbefore
described.
