PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Woollen, Worsted, Back-worsted,
Unions, and other Woven Fabrics.
1, ISAAC SMITH, of 41 King Street, Batley, in the County of York, Woollen
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method or process in the treatment of
woollen, worsted, back-worsted, unions and other woven fabrics, and hus for its
object the supercession of crabbing and steam blowing of such goods and consists in a
method of imparting solidity and a permanent finish and also a softness to such
fabrics and also securing a preparation of evenness necessary for the dyeing process.
In order to accomplish these improvements instead of passing the fabric through
the uncertain and injurious process of crabbing and steam blowing above referred to,
I pass the fabric through an apparatus known as a weegee, which comprises a trough
or cistern, near the bottom of which are mounted two rollers, and above the trough or
cistern two other rollers so arranged that they can be made to rotate alternately in
contrary directions. I fill the trough with water or other liquid in a boiling state
and place the piece of fabric therein, one of its ends being attached to one of the
upper rollers and the other end to the other upper roller, the piece of fabric passing
under the lower rollers. I impart a backward and forward miovenient to the fabric
or fabrics and for a suitable time according to the kind of fabric under treatment,
which has the effect of producing the required solidity, finish and softness not here-
tofore attainable by the old processes. To impart, the backward and forward move-
ment to the fabric the upper rollers are rotated by any suitable means such as a
pulley and bevel gearing.

1. ISAAC SMITH, of 11, King Street, Batley, in the County of York, Woollen
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 :-

the uncertain and injurious process of crabbing and steam blowing above referred to,
the fabric through an apparatus known as a weegee, which comprises a trough
or cistern, near the bottom of which are mounted two rollers, and above the trough or
cistern two other rollers so arranged that they can be made to rotate alternately in

I fill the trough with water or other liquid in a boiling state and place the piece of
fabric therein, one of its ends being attached to one of the upper rollers and the other
end to the other upper roller, the piece of fabric passing under the lower rollers. I
impart a backward and forward movement to the fabric or fabrics and for a suitable
time according to the kind of fabric under treatment, which has the effect of producing
the required solidity, finish and softness not heretofore attainable by the old process.

In order to explain more fully the nature of the abovenamed process according to
my invention I annex drawings of a weegee." Fig. 1. is a plan, Fig. 2. is an end

occur.

screws and handles, for braking that upper roller from which, for the time, the
fabric under treatment is being unwound.
:
In preparing the fabric for treatment, I elongate it by joining another piece of
fabric of less value than itself (usually canvas) to each end thereof so as to ensure the
ends of the fabric under treatment being always passed into the boiling liquid during
its backward and forward movement. I then pass one end of the fabric thus prepared
over one of the upper rollers, say, then beneath the lower rollers and up to the

roller e, being put in communication with the driving gear coils the fabric upon
until its rear end is in position for being and is attached to the upper roller c. The
roller is next by the movement of the clutch f, released from the driving gear
and the roller c², engaged therewith, the fabric becomes unwound from the roller c,
and coiled upon the roller c², and so on, passing it through the liquid backwards and
forwards, a braking being applied to that roller from which the fabric is being
uncoiled and thus a certain amount of tension is applied to the fabric according to the
nature thereof. The above described operations constitute the treatment above
referred to for producing the solidity, finish, softness and evenness required preparatory
to dyeing, which qualities are unattainable by the process hitherto in use.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The improved method or process in the treatment of Woollen, Worsted, Back-
worsted, Unions and other woven fabrics, for the production of solidity, finish
softness and evenness substantially as described, and preparatory to and for the purpose
specified.
