page_text: I WILLIAM MYCOCK of Spring Mill, Whitworth, near Rochdale, Calico Printer,
do hereby declare the nature of this invention to be as follows:-
My said invention relates to an improved construction of apparatus for stretching
or distending textile fabrics in the direction of their width.
According to my said invention I mount on a fixed shaft a series of separate discs
over and partly round which the fabric to be treated is caused to pass. The shaft on
which the discs are mounted is bent or arched so that the discs do not lie parallel to
each other. Planes passing through the respective discs form radii of the curve of
the shaft on which the discs are mounted so that from the centre of the shaft
outwards the discs are inclined at successively increasing angles to the vertical.
The discs are serrated or otherwise formed so as to engage with each other at their
edges of contact. The outer faces or peripheries of the discs are grooved corrugated,
serrated roughened or otherwise fashioned so as to provide a "bite" or holding
surface for the cloth. In one form of my said invention the discs are provided with
ball bearings running either directly on the curved shaft or on bushes or collars.
thereon.
In order to vary the amount of distension I provide an accessory regulating roller
for causing the cloth to pass round a greater or less part of the periphery of the
discs. Such a construction lends itself to the use of very light discs so that
the distending apparatus may be used for the finest fabrics.
In some cases I make such discs from dished plates of thin metal with attached
rims or peripheries.

I WILLIAM MYCOCK of Spring Mill, Whitworth, near Rochdale, Calico Printer,
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 said invention relates to an improved construction of apparatus for stretching
or distending textile fabrics in the direction of their width.
In order that my said invention may be more clearly understood, I will describe
the same with reference to the accompanying drawings in all the figures of which the
same letters refer to the same parts.
Figure 1 is a front elevation of any invention.
Figure 2 is a section through y-y of Figure 1.
Figure 3 is a

Figure 2 illustrates in plan details to be hereinafter described.
partial elevation of one of the discs. Figure 4 is a section through
Figure 5 illustrates in plan one of the bobbins of the regulating roller.
According to my said invention I mount on a fixed shaft aa series of separate
discs b over and partly round which the fabric c to be treated is caused to pass.
The shaft a on which the discs b are mounted is bent or arched so that the discs b
do not lie parallel to each other. Planes passing through the respective discs forin
radii of the curve of the shaft on which the disos are mounted so that from the
centre of the shaft outwards the discs are inclined at successively increasing angles
to the vertical. The discs bare serrated or otherwise formned so as to engage with
each other at their edges of contact. The outer faces or peripheries of the dises b
are grooved corrugated serrated roughened or otherwise fashioned so as to provide
"bite" or holding surface for the fabric. In one form of my said invention I
provide the discs b with ball bearings as shown at Figures 3 and 4 running on the
curved shaft a or in some cases I may run them on bushes or collars on the shaft as
will be well understood. The balls bare inserted at each side of the disc b as shown
at Figure 4 and are held in position by the sorewed oups 6. The outer edges of the
cups 6 are provided with teeth at 63 so as to form a rough surface to enable it to be
rotated by hand (when the halls want tightening or become worn) in order to adjust
the disc. To prevent the cups 6 rotating when the disc is running on the shaft a
I provide a rod d mounted in guides d on the arm of the disc b and having its
inner end d formed flat with teeth engaging with the teeth 68 of the cups. The
end of the said rod is kept in engagement with the teeth of the cups by
the pressure of the spring d. When it is desired to rotate the cups 6' the spring
rodd is pulled out of engagement with the oups by means of a hook taking into
the bole d in the rod. In the drawing only six discs are shown, but it is to be
understood that a greater number according to the width of the fabric may
be employed. The discs are kept together on the shaft a by collars a¹ and set screws
bearing against the outside disc at each side. Such a coustraction lends itself to
the use of very light discs so that the distending apparatus may be used for the
finest fabrics.
In order to vary the amount of distension I provide accessory regulating rollers e e¹
as shown at Figure 5 consisting of sections with their edges of contact serrated or
otherwise formed so as to engage with each other. These sections are mounted on
fixed arched or curved shafts e²e secured to the frame g by means of brackets ƒ ƒ¹
provided with slots h h' to enable the rollers e e¹ to be slid forwards or backwards in
order to cause the fabric c to pass round a greater or less part of the periphery of
the discs b. These sections or bobbins forming the regulating rollers e e' being on

page_text: curved or bent shafts do not lie parallel to each other and have their peripheries or
outer faces grooved corrugated serrated or otherwise fashioned so as to provide a
"bite" or holding surface for the fabric. The fabric c as it enters the apparatus
passes over the lower regulating roller e¹, then over part of the periphery of the
discs b where it is distended to the upper regulating roller e as indicated in dotted
lines at Figure 2. The lower regulating roller e¹ slightly distends the fabric before
it reaches the discs baud on reaching the upper regulating roller the fabric is again
slightly distended.
Although I have shown particular constructions of discs and sections for the
rullers it is to be understood that these are merely illustrations of what I find to be
a satisfactory method of carrying out my said invention which is not limited to
these precise constructions. I might for example use discs made from dished plates
of thin metal with attached rims or peripheries.
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 :-
1. In-apparatus for stretching-or-distending textile fabrics-a-bent-or-curved-bar
having a series of interlocking or mutually engaging stretching dises or sections
mounted radially thereon-substantially-as-set forth-and-shown
In apparatus for stretching or distending textile fabrics the combination with
a bent or curved shaft and radially mounted stretching discs or sections of curved
accessory bars carrying radially mounted sections or rollers for varying the amount
of stretch substantially as set forth and shown.
