PROVISIONAL SPECIFICATION.
Improved Roller for Stretching or Removing Creases from Fabrics.
I, JOHN THOMAS RIGG, of Moseley Terrace, Chippenham, in the County of
Wiltshire, Mechanic, do hereby declare the nature of this invention to be as
follows:-
The invention relates to rollers, for stretching or removing creases from woven
fabrics such as are chiefly used in connection with machines for finishing cotton,
woollen, silk or other fabrics.
It consists essentially of a central shaft upon which is mounted a number of
bushes, the holes in which are cast or otherwise formed so that their outer surfaces
or peripheries incline in one or more directions and upon these bushes are mounted
free to revolve a number of pulleys the peripheries of which are formed either
convex or inclined in one or more directions and against which the fabric to be
stretched comes in contact.
In carrying out the invention 1 mount a shaft, preferably square in cross
section, at a convenient position near the end of the machine at which the cloth
enters, and upon this shaft I mount or fix a number of bushes the holes in which
are made to incline in one or more directions relatively to the peripheries of the
said bushes, so that the wooden or other rollers afterwards mounted upon them will
follow the inclination of the holes. One half of the number of bushes employed
incline in an opposite direction to the other half. The rollers mounted upon the
bushes may be made of wood or other suitable material, with their peripheries
preferably made convex or inclined to their axes in one or more directions. The
space left in the centre. of the stretching roller between the two sets of rollers may
be filled up with a stationary or rotatable wooden piece, the periphery of which is
formed in a similar manner to the wooden rollers. The ends of the rollers may be
finished off with stationary wooden blocks inclined on one side to the angle of the
rollers, and on the other formed square. The bushes on which the wooden rollers
are mounted are made slightly longer than the rollers themselves so that the latter
are free to revolve. The whole set of bushes may be kept together by any
suitable means such as adjustable collars or screws and nuts.
When in use the cloth is passed over the roller and stretched by the action of
the wooden rollers mounted upon the bushes.

Improved Roller for Stretching or Removing Creases from Fabrics.
I, JOHN THOMAS RIGG of Moseley Terrace, Chippenham in the County of
Wiltshire, Mechanic 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 invention relates to rollers for stretching or removing creases from woven
fabrics such as are chiefly used in connection with machines for finishing cotton,
woollen, silk or other fabrics.
It consists essentially of a central shaft upon which is mounted a number of
bushes, the holes in which are cast or otherwise formed so that their outer surfaces

free to revolve, a number of pulleys the peripheries of which are formed either
convex or inclined in one or more directions and against which the fabric to be
stretched,comes in contact..
The invention will be fully described with reference to the accompanying drawings
in which Fig. 1 shows an elevation of the improved roller, Fig. 2 a longitudinal
section, Fig. 3 an end view with central shaft in section whilst Figs. 4 and 5 show
two views of one of the metal bushes.
As will be seen from these drawings a central shaft A is provided which may be
mounted in a convenient position at the end of the machine at which the cloth
enters. The shaft A is preferably square in cross-section and upon it is threaded
or mounted a number of bushes the holes in some of which are made to incline
in one or more directions relatively to the central shaft as shown clearly in Figs. 4
and 5 whilst the holes in the bushes at the central portion of the roller are formed
parallel with the shaft. Upon the bushes B are mounted free to turn thereon
pulleys or rollers C made of wood or other suitable material. The pulleys on the
outside series of bushes take the form of conic frustums the angle of which is such
that the several upper surfaces form an approximately straight line as shown in
Fig. 2, whilst the pulleys or rollers mounted on the central bushes are "square
with the shaft and are separated from the others by wooden wedge-shape blocks C'
which fit directly on the shaft without the intervention of a bush. Similar wedge-
shaped blocks C are placed at either end of the roller. The blocks C¹ and C₁f it
will be understood are prevented from turning owing to being fitted directly on the
square shaft as described.

The bushes B are made in each case slightly longer than the rollers mounted
upon them so that when the former are clamped together by the end flanges the
latter are quite free to rotate. If desired the ends of the shafts A may be screwed
and nuts placed on them to tighten up the bushes though it will be quite evident
to the practical engineer that there are many ways of doing this.
I would have it understood that the number of rollers C will depend upon the
width of the fabric passing over them and that also the number of central rollers
will vary according to the quality or strength of the fabrics being stretched since
it would be sometimes desirable to have more central rollers than shewn and some-
times less. The angularity of the inclined rollers will also depend to a large extent
upon the quality of the goods being treated.
When in operation the cloth is led round suitable guides which force it into
contact with the rollers the peculiar arrangement of which causes them to exert a
stretching action on the cloth sufficient to remove creases.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, declare that what I
claim is
The improved roller for stretching or removing creases from fabrics constructed.
and arranged substantially as described and as shown by the accompanying
drawings.
