AN IMPROVED MACHINE FOR STRETCHING AND SHAKING OUT YARN
Year: 1877

page_text: LETTERS PATENT to Robert Kay Whitehead, of Long Croft, Walmersley, near
Bury, in the County of Lancaster, Bleacher, for the Invention of "AN IMPROVED
MACHINE FOR STRETCHING AND SHAKING OUT YARN."
Sealed the 21st August 1877, and dated the 31st March 1877.
PROVISIONAL SPECIFICATION left by the said Robert Kay Whitehead at
the Office of the Commissioners of Patents on the 31st March 1877.
ROBERT KAY WHITEHEAD, of Long Croft, Walmersley, near Bury, in the County
of Lancaster, Bleacher. "AN IMPROVED MACHINE FOR STRETCHING AND SHAKING
OUT YARN."
The object of this machine is to take out all snarls or curls from yarn when in
the hank or doffin, whereby the manual labour is considerably reduced and a better
result obtained.
The machine consists of a roller to which a slow rotary motion is given by steam
or other power, and of a bar to which an up-and-down or to-and-fro motion is given
by a crank, a connecting rod to which is attached a spring with flexible bands
connected to a cross head, through which the bar passes.
The banks or doffins of yarn are placed around the roller and the bar, and when
the machine is set to work the roller revolves slowly, while the crank imparts an
up-and-down or to-and-fro motion to the bar, which acts on the yarn and effectually
removes all the snarls or curls.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Robert Kay Whitehead in the Great Seal Patent Office on the 27th
September 1877.
ROBERT KAY WHITEHEAD, of Long Croft, Walmersley, near Bury, in the County
.of Lancaster, Bleacher. "AN IMPROVED MACHINE FOR STRETCHING AND SHAKING
OUT YARN."
The object of this machine is to take out all snarls or curls from yarn when in
the hank or doffin, whereby manual labour is considerably reduced and a better
result obtained.

page_text: The machine consists of a roller to which a slow rotary motion is given by steam
or other power, and of a bar to which an up-and-down or to-and-fro motion is given
by a crank, a connecting rod to which is attached a spring with flexible bands or
links connected to a cross head, through which the bar passes.
The hanks or doffins of yarn are placed around the roller and the bar, and when
the machine is set to work the roller revolves slowly, while the crank imparts an
up-and-down or to-and-fro motion to the bar, which acts on the yarn and effectually
removes the snarls or curls.
And in order that my Invention may be fully understood and readily carried into
operation, I will proceed to describe the accompanying Sheet of Drawings, in 1
which Fig. 1 is a side view, and Fig. 2 a front elevation of the machine for stretching
or shaking out hanks or doffins of yarn, either unbleached, bleached, dyed, or
printed, or in any other condition.
The machine consists of the standard a, to which are cast or fixed the bearings
for the axle b of the rollers c; c, to which a slow rotary motion is given, as will be 1
explained hereafter. Below the rollers c, c, is the bar d, the outer ends of which
are coated with tubes of zinc or other non-corrosive metal or material to prevent
rust. The bar & is fixed in the slide e fitting in a V groove in the standard a, and
this slide is connected by the links ff, to the spring g, fixed to the slide h, which
also fits in the V groove in the standard; the slide h is connected by the rod i to
the adjustable crank pinj projecting from the face plate k fixed to the driving
axle l, which revolves in bearings in the standard.
The machino is driven by a strap passing around the pulley which is loose on
the axle 6, but connected to it when required by the friction cone 12, which fits on a
key in the axle, and is moved to and fro by the starting lever m. To the pulley
is cast or fixed the small grooved pulley, which by a band drives the pulley n fixed
to the axle n¹, on which is also fixed the bevel pinion n gearing into the wheel b
fixed to the axlo b; by this or any equivalent gearing the rollers c, c, are caused to
rotato slowly.
When the hanks or doffins of yarn have been placed around the rollers c, c, and
bar d, as shewn in the Drawing, and when the machine has been set to work by the
attendant moving the friction cone into contact with the cone inside the driving
pulley, the crank pin j imparts a rapid up-and-down motion to the bar d, which
acts on the inside of the hanks or doflins, and a slow rotary motion to the rollers c, c,
to vary the position of the hanks or doffins, so that the bar d may always be striking
on fresh portions of the yarn. By this means the hanks or doffins are stretched and
shaken out, thereby removing snarls or curls from the yarn; the manual labour
hitherto employed to effect the same object is economised, and a better result is
obtained.
Having thus stated the nature of my Invention, and described the manner of
performing the same, I wish it to be understood that I do not intend to limit myself
to the details given, and that I claim the machinery for stretching and shaking out
hanks or doffins of yarn, as shewn and described in reference to the accompanying
Sheet of Drawings or any modification thereof, whereby elastic strokes are given to
the yarn.
In witness whereof, I, the said Robert Kay Whitehead, have hereunto set my
hand and seal, this Twenty-sixth day of September, One thousand eight
