PROVISIONAL SPECIFICATION.
Buffs and Pads for Burnishing and Polishing.
THOMAS MARSDEN COCKROFT of 67 Burley Lodge Terrace Leeds, Manager
do hereby declare the nature of this invention to be as follows:-
-
My invention pertains to buffs and pads for burnishing and polishing leather,
boots, and metallic goods generally; and relates more particularly to a process of
manufacturing such buffs of a homogeneous structure throughout, direct from
carded wool fibres, whereby such goods may be made less costly and without the
disadvantage of the raw edge and waste consequent upon cutting circular discs from
a flat piece of felt.
In carrying out my invention, I take carded wool as doft from the carding
engine, and form a spherical ball of same; I now wind a binding thread of woollen
yarn around said spherical ball and place four or more of said balls upon the
rotating disc described in Specification of Patent No. 15664 A.D. 1894.
I spray said bails by means of a steam or hot water jet during their rotation
upon said dise, and continue the rotation of the balls until their outer surfaces are
partly "hardened." I now take said balls, and submit them whilest still warm and
moist to vibrating pressure under a vertical bumper, until the ball is reduced to a
piece of flat circular felt of the desired compactness.
To produce a buff or pad of a cylindrical shape, I take the ball when partly
"hardened " on rotating disc and submit said ball whilest still warm aud moist to
pressure and friction by rolling betwixt a stationary and a reciprocating board.
The buffs and pads are now suitable for use where a soft and yielding surface is
required, but for other purposes greater rigidity may be required, I secure such
rigidity by closely stitching through the felt and thereby knitting the body of felt
into a rigid condition.
Dated this the Seventh day of October 1895.

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:-
My invention pertains to buffs and pads for burnishing and polishing leather,
boots, ivory, bone, and metallic goods generally; and relates more particularly to a
process of manufacturing such buffs of a homogeneous structure throughout, direct
from carded wool fibres, whereby such goods may be made less costly and without
the disadvantage of the raw edge and waste consequent upon cutting circular discs
from a flat piece of felt.
In carrying out my invention, I take carded wool as doft from the carding
engine, and form a spherical ball of same, I now wind a binding thread of woollen

I spray said balls by means of a steam or hot water jet during their rotation
upon said disc, and continue the rotation of the balls until their outer surfaces are
partly hardened." I now take said balls, and submit them whilest still warm and
moist to vibrating pressure under a vertical bumper, until the ball is reduced to a
piece of flat circular felt of the desired compactness.
"
To produce a buff or pad of a cylindrical shape B', I take the ball B when
partly "hardened on rotating disc and submit said ball whilst still warm and
moist to pressure and friction by rolling betwixt a stationary and a reciprocating
board.
The buffs and pads are now suitable for use where a soft and yielding surface
is required, but for other purposes where greater rigidity may be required,
I secure such rigidity by closely stitching through the felt and thus knitt the body
of felt thereby into a rigid condition.
I will now proceed to more particularly describe my invention by the aid of the
drawings hereto annexed, in which :-
Fig. 1, is a view of the wool fibres formed into a spherical ball and bound with
binding thread A.
Fig. 2, is a view of the ball B "partly hardened."
Fig. 3, views of ball B reduced to circular shape and finished by stitching C;
Fig. 3 the same rolled into cylindrical shape.
Fig. 4, a front view of a machine adapted to reduce the ball B from a spherical
to a flat circular condition.
The ball B as illustrated in Fig. 2 is placed upon the adjustable platform D, and
submitted successively to the action of the vertical bumpers E, which receive their
motion from rod F through levers G, as shown in dotted lines.
The platforms D are adjusted to gradually increase the pressure upon B as they
pass successively under bumpers E, from right to left of the machine.
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. As a new article of manufacture, a buff or circular disc of felt, made
from a spherical ball of wool fibres, felted by rotation and reduced to a circular
shape by vertical bumping, and knitted together by stitching as herein set forth.
2. As a new article of manufacture, a buff or cylindrical roll of felt, made from
a spherical ball of wool fibres, feltel by rotation, reduced to a cylindrical shape by
rolling and pressure between two boards as herein specified.
3. The process of manufacturing circular felt butts, or cylindrical rolls of felt, by
forming a spherical ball of wool fibres, binding same by a woollen binding thread,
felting and shaping by rotating, bumping, or rolling as herein described.
4. The machine for reducing spherical balls of felt into a circular disc as hercin
illustrated and described.
Dated this the Seventh day of July 1896.
