Improvements in the Manufacture of Pouches, Pockets, Purses, Bags,
and like Articles.
THOMAS MARSDEN COCKROFT of 67 Burley Lodge Terrace in the City of
Leeds, Depôt Manager, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manufacture of pouches, pockets, purses, bags and
the like articles, direct from carded feltable fibres; and more perticularly to a
method of manufacturing such articles without seam or joining.
In carrying out my invention, I take an indiarubber form with an inflater pipe
connected thereto, which when inflated with atmospheric air, will be of an
approximately spherical shape. I cover said form by winding a narrow "sliver
of carded wool around it until I obtain a sufficient equal thickness over the surface
of said form. I bind said carded wool covering to said form by winding a thread of
botany yarn thereon, so that said botany threads cross in every direction and
securely hold the wool covering to said form during the preliminary stage of
subsequent treatment.
I now saturate said wool covering with warm soapy water, and then place three
or more of the wool covered forms upon a rotating disc; said disc communicates a
rotary motion to said forms and causes them to rub one against the other of them,
and thus partially felt and shrink said coverings into close contact with said forms;
when this stage in the process reached, slightly deflate said forms and then
place upon the disc for another period of rotation, until the coverings have again
shrunk into close contact with said forms. I repeat this process of successively
deflating and rotating upon the disc, until said coverings have been shrunk to the
desired size. I keep the coverings during the operation of felting on said disc well
saturated with hot water by occasionally spraying with same.
I now withdraw said form and fold the felted covering into a half spherical shape
and pile a dozen or more of said felted coverings one on the top of the other, and
submit said pile to vibrating pressure under a vertical bumper, frequently changing
the relative positions of said coverings to each other, and keeping them well soaked
with hot water, until the said half spherical coverings are reduced approximately

this state and submit them to pressure and friction under a pair of rolls, putting

more work into the felt in the direction in which it is desired to extend or
it to form oval articles.
I may so fold the felt coverings (after withdrawal of said form and before
submitting them to the action of said bumper) so that the withdrawal hole may be
on the periphery of said flat felt article; for some purposes, I divide the said flat
felt article at the withdrawal hole, slitting the felt on both sides of said hole, until
the opening thus made is wide enough, or 1 may so fold said coverings that the
withdrawal hole shall be nearly central of said flat piece of felt; in this case, I slit
the felt from the hole on both sides to the edge of said felt, thus making an upper
and lower pocket connected together by a continuous back of felt, said pockets
folding one within the other, in a manner similiar to the well known Horsey
tobacco pouch.

THOMAS MARSDEN COCKROFT 67 Burley Lodge Terrace Leeds Depôt
Manager, 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 relates to the manufacture of tobacco pouches, decorative pockets,
purses, hand and work bags, and like articles, direct from carded wool fibres, and
more particularly to a method of manufacturing such articles without seam or
joining.
I will now proceed to describe my invention by the aid of the drawings hereto
anuexed, in which corresponding letters, denote corresponding parts in all the
figures.
In carrying out my invention, I take an indiarubber form A, with an inflater
pipe connected thereto, which when inflated with atmospheric air will be of an
approximately spherical shape, as shewn in dotted line in Fig. 1. I cover said
form A, by winding a narrow "sliver" of carded wool B around it, until I obtain
a sufficient equal thickness over the surface of form A. I bind said carded wool B
to said form by winding a thread of botany yarn C thereon, so that said botany
yarn C crosses in every direction and securely holds carded wool B to form A
during preliminary stages of subsequent treatment.
I now saturate the wool covered form as shewn in Fig. 1, with warm soapy water,
and then place three or more such forms upon a rotating disc; said disc com-
municates a rotary motion to said forms, and causes them to rub one against the
other of them, and thus partially felt and shrink wool fibres B into close contact
with form A; when this stage in the process is reached, I slightly deflate form A
and then place upon the disc for another period of rotation, until the covering B
has again shrunk into close contact with form A. I repeat this process of
successively deflating and rotating upon the disc, until the covering B has been
shrunk to the desired size. I keep the forms during the operation of felting on said
disc, well saturated with hot water by occasionally spraying with same.
Fig. 2 illustrates the felt in section immediately before deflation and withdrawal
of form A; afterwards the resultant felt bodies Ď are folded into a half spherical
shape, and a dozen or more of such bodies D are superimposed (see Fig. 3) into a
pile and submitted to vibrating pressure under a vertical bumper E, Fig. 8,
frequently changing the relative positions of said bodies D to cach other, and
keeping them well soaked with hot water, until bodies D are reduced approximately
to the shape of a double piece of flat circular felt.
Fig. 7 and 8 illustrate a machine adapted to reduce felt bodies D to a flat
condition, in which Fig. 7 is an end view and Fig. 8 a side view; E being a
vibrating bumper, secured to reciprocating shaft F, said shaft F receiving motion
through crank disc G and link H. Platform I on which bodies D are piled is
adjusted vertically by screw K. I take bodies D as they come from treatment
under machine shewn in Figs. 7 and 8, and submit them to pressure and friction
under a pair of rolls; putting more work into the felt in the direction in which it is
desired to extend or 'draw it to form oval articles, or putting equal work in all
directions for the production of circular bodies.

page_text: I may so fold bodies D after withdrawal of form A, and before submitting them
to the action of said bumper, so that the withdrawal hole may be on the periphery
of said body, as at L in Fig. 5; for some purposes, I divide body D at the with-
drawal hole L, slitting body D on both sides of said hole until the opening thus
made is wide enough, or I may so fold body D, that the withdrawal hole L shall
be nearly central of body D, (see Figs. 4 and 6 and section of Fig. 3) in this case,
I slit body D from the hole L on both sides to the edge thereof, thus making an
upper and lower pocket connected together by a continuous back of felt, (as shewn
in Fig. 4) said pockets folding one within the other, in a manner similiar to the well-
known Horsey pouch.
For other purposes,
may take body D, "draw" to an oval shape as herein set
forth, with the withdrawal hole L Fig. 6 nearly central of such oval, and slit com-
pletely across both thicknesses of felt on dotted line a, a, thus obtaining two distinct
pockets or bags from one body D.
Having now particularly described and ascertained the nature of my inven-
tion, 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 pouch, pocket, purse, bag, or like article of
felt without seam or joining, substantially as herein described and illustrated.
2. The process of manufacturing pouches, pockets, purses, bags, or like articles,
by applying feltable fibres B, and yarn C to form A, felting same by rotation upon
a disc, subsequently treating under bumper E, drawing" out by means of rolls,
and slitting in the manner herein set forth.
Dated this the Third day of August 1895.
