IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1877

page_text: LETTERS PATENT to John Butterworth and William Dickinson, both of Burnley,
in the County of Lancaster, Machinists, and Thomas Howard Blamires, of
Huddersfield, in the County of York, Woollen Manufacturer and Yarn Spinner,
for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 3rd July 1877, and dated the 4th January 1877.
PROVISIONAL SPECIFICATION left by the said John Butterworth, William
Dickinson, and Thomas Howard Blamires at the Office of the Commissioners
of Patents on the 4th January 1877.
JOHN BUTTERWORTH and WILLIAM DICKINSON, both of Burnley, in the County
of Lancaster, Machinists, and THOMAS HOWARD BLAMIRES, of Huddersfield, in the
County of York, Woollen Manufacturer and Yarn Spinner. "IMPROVEMENTS IN
LOOMS FOR WEAVING."
The object of this Invention is the adjustment and timing of the motion of the
cloth beam or of the "friction roller" of looms for weaving, so as to secure con-
tinuous, positive, uniform, and regular taking up of the cloth, and thus producing a
more even, uniform, and superior cloth.
The apparatus consists of an improved combination and arrangement of mechanism
for imparting positive and continuous motion to cloth beam or to the friction roller
for taking up the cloth as woven. We employ a worm shaft driven from the crank
shaft by clutch, bevil, spur, or worm gear; the worm or other gear imparts positive
and continuous motion to the cloth roller or to the friction roller (as the case may
be), on the axis of which is a "change" pinion; the latter gears with the ordinary
spur wheel on the shaft of the cloth beam or of the friction roller, and so positive
and continuous notion is secured. There is a hand wheel or a lever for reversing
or turning back the cloth beam or the friction roller by which and by use of the
"clutch" herein-before referred to, the cloth beam or the friction roller (or either of
them) may be turned or reversed for "letting back" when the loom is not at
work.
Another arrangement where no friction rollers are used, such as broad or heavy
woollen cloth looms, consists of a shaft driven directly or indirectly by bevil gear,
D

page_text: spur, or worm gear from the crank shaft, and on the shaft first referred to is also
a cone speed pulley. A second shaft having cone speed pulley and a worm, the
latter gears with a wheel which gives motion to the cloth beam. The cone pulleys
referred to are connected by a driving strap. On the cloth beam we place a friction
roller, attached to which are levers which are connected with the driving strap of
the cone speed pulleys.
As the cloth beam increases or varies in diameter, the levers referred to move the
driving strap on the cones, and so give a continuous, uniform and even winding of
the cloth upon the cloth beam.
In some cases we communicate motion from the crank shaft to the cloth beam or
to the friction roller by a train of spur gear.
We may employ for winding off the warp regularly from the beam so as to give
uniform tension on the warp a lever, one end of which carries a friction roller or
"runner" moved or driven by frictional contact with the warp, the said friction"
roller or runner is connected with a screw or screws, which latter move the weight
or weights on the weight lever or levers, so as to give uniform weight or tension on
the warp during its varying diameters.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Butterworth, William Dickinson, and Thomas Howard Blamires
in the Great Seal Patent Office on the 4th July 1877.
JOHN BUTTERWORTH and WILLIAM DICKINSON, both of Burnley, in the County

LOOMS FOR WEAVING."
The object of this Invention is the adjustment and timing of the motion of the
cloth beam or of the friction roller of looms for weaving, so as to secure continuous,
positive, uniform, and regular taking up of the cloth, and thus producing a more even,
uniform, and superior cloth.
The apparatus consists of an improved combination and arrangement of mechanism
for imparting positive and continuous motion to cloth beam or to the friction
rollers for taking up the cloth as woven. We employ a worm shaft driven from
the crank shaft by clutch, bevel, spur, or worm wheel; the worm or other gear
imparts positive and continuous motion to the cloth roller or to the friction roller
(as the case may be), on the axis of which is a change pinion, the latter gears with
the ordinary spur wheel on the shaft of the cloth beam or of the friction roller, and
so continuous and positive motion is secured.
Another arrangement where no friction rollers are used, such as broad or heavy
woollen cloth looms, consists of a shaft driven directly or indirectly by bevel gear,
spur, or worm gear from the crank shaft, and on the shaft first referred to is also
a cone speed pulley. A second shaft having cone speed pulley and a worm, the
latter gears with a wheel which gives motion to the cloth beam; the cone pulleys
referred to are connected by a driving strap. On the cloth beam we place a friction
roller, attached to which are levers connected with the driving strap of the cone
speed pulleys.
As the cloth beam increases or varies in diameter the levers referred to move the
driving strap on the cones, and so give a continuous, uniform and even winding of
the cloth upon the cloth beam.
In some cases we communicate motion from the crank shaft to the cloth beam or
to the friction roller by a train of spur gear.
Such being the nature and object of this our said Invention, we will now proceed
to describe the particulars thercof, and have annexed hereto a Sheet of Drawings on
which at A is the worm shaft driven from the crank shaft B by clutch, bevel, spur,

page_text: or worm gear C; the worm D or other gear imparts positive and continuous motion
to the cloth roller E, or to the friction rollers E¹, on the axis of which is a change
pinion F, the latter gears with the ordinary spur wheel G on the shaft of the cloth
beam E or of the friction roller E¹, and so positive and continuous motion is
secured.
When the weft or yarn breaks the worm shaft A is raised or lifted by the action
of the ordinary apparatus of the weft fork, the arm H is at the same time raised,
bringing the teeth J thereon into gear with the teeth of the wheel K, so locking
the shaft A and preventing the cloth beam or the cloth running back whilst the
worm shaft is in its raised position.
Fig. 5 is a modification of the holding or locking apparatus (above described) in
which a catch and ratchet wheel are employed.
Another arrangement where no friction rollers are used, such as broad or heavy
woollen cloth looms, consists of a shaft A driven directly or indirectly by bevel gear,
spur, or worm gear from the crank shaft B, and on the shaft first referred to is also
a cone speed pulley C, a second shaft D having cone speed pulley E and a worm F;
the latter gears with a wheel G which gives motion to the cloth beam H by the
pinion J and spur wheel K. The cone pulleys referred to are connected by driving
sprap N. On the cloth beam H we place a friction roller W, attached to which are
levers L and M connected with the driving strap N of the cone or speed pulleys E
and C.
As the cloth beam increases or varies in diameter the levers L and M referred to
move the driving strap N on the cones E and C, and so give a continuous, even,
and uniform winding of the cloth upon the cloth bean.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, we would have it understood that what we claim as our Invention
and believe to be new within the realm is, the combination and arrangement of
of mechanism, as shewn and described for the purpose herein set forth.
In witness whereof, I, the said Thomas Howard Blamires, for and on behalf
of myself and the said John Butterworth and William Dickinson, have here-
unto set my hand and seal, this Twenty-sixth day of June, in the year of
our Lord One thousand eight hundred and seventy-seven.
