PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow at
the Office of the Commissioners of Patents on the 10th July 1877.
HENRY BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent. "IMPROVEMENTS IN WARPING FRAMES." A. cominunication from abroad
by José M. Dalmau, of Barcelona, in Spain.
The object of this Invention is to facilitate the winding and distributing of the
yarns on the beam.
The improved warping frame consists of a reed, which is moved up and down to
cross the yarns or to take the lease; also a measuring roller, around which the yarns
pass, and a series of grooved pulleys to separate the warp into divisions.
The yarns proceeding from the bobbins of the creel pass under and over guide
rods, and through the dents of the movable reed, then over the measuring roller and
under a tension roller, then under the ordinary taking-up bars, and then over the
grooved pulleys to the beam, the number of these grooved pulleys and the number
of yarns in each depends on the warp. These grooved pulleys are moved to and
fro end wise by a heart or other equivalent to distribute the yarn evenly on the
beam.
In some cases a comb may be substituted for the grooved pulleys.
To the measuring roller above referred to is connected a counting apparatus,
consisting of a train of wheels and pinions with dials and pointers, and an apparatus
for marking the warp when a certain length has been wound on, the beam -con-

page_text: sisting of a brush and a paint trough, the brush being actuated by a worm, and
wheel, and lever, when the measuring roller has performed 50 or other definite
number of rotations.
The warping frame is driven by hand or power.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Henry Bernoulli Barlow in the Great Seal Patent Office on
the 9th January 1878.

And in order that this Invention may be fully understood and readily carried
into operation; I will proceed to describe the accompanying two Sheets of Drawings,
reference being had to the figures and letters marked thereon.
On Sheet 1, Fig. 1 is a vertical section of the improved warping frame taken
through the line 1, 2, of Fig. 2, which is a plan of the same; and Fig. 3 is a front
view.
This frame can be employed for every description of yarn.
The yarns forming the warp can be divided into any number of parts by means
of small grooved pulleys. The yarns can easily be crossed to take the lease, thereby
dispensing with the dressing frame.
The peculiar feature of novelty in this machine is the up-and-down motion of a
comb for crossing the yarns, the measuring roller and the small grooved pulleys each
containing a certain number of yarns to suit the warp; these grooved pulleys are
moved to and fro to distribute the yarn on the beam.
The length of the warp is recorded on an indicator, and the warp is divided into
-lengths by a self-acting brush in the ordinary manner.
The machine can be stopped and started at any time automatically, so as to cross
the yarns or take the lease after every 50 yards or other definite length has been
wound on the beam."
The friction roller a is driven direct when steam or other power is used, or by
the fly wheel V, handle v, and toothed wheels b when driven by hand.
The warp beam A is driven by the friction of the roller a, and rises in slots cas
.it increases in diameter; or the roller a may be dispensed with, and the beam A
driven direct.
The small grooved pulleys B divide the warp. into 16, or other convenient
number of parts; these pulleys are moved to and fro endwise by the eccentric C;
Dare the taking-up rods; and F, the measuring roller which drives the indicator G
and governs the stopping and starting of the machine; H is the comb or reed,
which is actuated by the handle I; J is the marker, and K, the open reed to
distribute the yarns from the reel. The tension rods m, n, and o are to support
the yarns while they are being crossed.
When the cross bar M is reversed it brings the small pulleys B below and the
open comb Pabove, thereby allowing the yarns to be wound evenly over the
heam

page_text: The frame containing the little pulleys B and the open comb P can be lowered to
allow the crossings of the yarn to pass.
s are the handles of the rods for stopping wher. the yarn breaks; X represents
the mode of bending the ends of the framing supporting the open comb K and the
tension bars n, o, to facilitate the piecing up of broken ends. The supports Z are
for extra bobbins.
The supplemental rollers F1, F", are covered with flannel to increase the drag
on the yarns and to make the measuring more accurate.
The machine may be provided with. reversing pulleys, if required, to drive in
either direction, and as many as 400 yarns can be wound. This machine, with a
sizing and dressing frame, suffices to prepare the warp for the loom; or when
the warp does not require sizing this machine is sufficient.
On Sheet 2 I have shewn a self-acting apparatus for stopping the warping frame
on a yarn being broken.
Fig. 1 is an elevation; Fig, 2, a plan; and Fig. 3, a front view of the machine.
The apparatus consists of the pieces a, the number of which corresponds to the
number of yarns. The pieces a are supported by the cross rail b; the end a¹ of
each piece a has a recess for the yarn to pass through, and the other end a¹¹ is
weighted; this weighted end falls on the light frame c, which is guided in the
supports d.
The lower end of the frame c bears upon the lever f, and the frame is
counterbalanced by the weight g. The extremity of the lever f lifts the end i of
the equilibrium lever j, which is provided at k with an incline to receive the
impact of the four studs projecting from the driving pulley m, thus causing the
lever j to vibrate and to produce the disengagement of the spring o acting on
the strap guide q.
The pieces a are thrown out of action when required by the bar p and handle s.
The mode of operation is as follows:-When the machine is at work the
yarns, passing through the recesses a¹, hold the pieces a horizontal, as shewn, the
levers, above described, remain inactive, and the end of the lever j allows the studs
7 of the driving pulley m to pass without touching; but as soon as an end
breaks, the piece a falls into the position indicated by the dotted lines, and brings
the weighted.end a¹ against the light frame c; the lever f is then inclined, and its
extremity h lifts the end i of the lever j until the end is lowered to receive the
impact of one of the studs in the pulley m. The lever then strikes the
piston n of the lever p, which forces back the spring o, which, acting on the strap
guide q, moves the strap from the fast to the loose pulley. The broken end can
now be pieced up, and the yarn replaced in the recess a¹; the piece a then regains
its horizontal position as before.
When the machine is driven by hand the falling of the piece a causes a blow
to be struck on a bell to give notice to the attendant.
Fig. 4 represents a modification of this part of the Invention.
As in the foregoing example the pieces a are loose on the cross bar b, the
end a¹ is recessed, and the end a¹ is connected to the oscillating piece c.
The bar d is equal in length to the width of the yarns, and is moved rapidly to
and fro by the levers e, f, link g, and wheels h, i.
Another bar k, placed near to d, carries the lever 1, which vibrates on the axle m;
this lever has a bowl n which holds the starting lever o by a catch so as to keep
the strap on the driving pulley, and there is a spring to bring the strap on to the
loose pulley. The springs t on the bar hold the bowl n in position. The combs
or reeds u, v, a, guide the yarns and the pieces a, and near the ends a' there is a
small hole for holding a portion of the pieces out of action when required. The bar
ย has hooks upon it taking into the said holes.
z
The whole set of pieces a can be raised out of action by the bar when required.
When all the pieces a are held horizontal by the yarns, and the bar d is moving
to and fro, it passes close to the bark without touching it, but when an end breaks
the end of the corresponding piece a, and the piece c drop between the bars d

page_text: and h, the former then pushes the latter to the extent of the thickness of the piece c,
minus the play. The bowl n is then withdrawn, and the driving strap is moved
on to the loose pulley by the starting lever o, thus stopping the machine.
When the broken end has been pieced up, the piece a regains its former position,
and the machine is again started in the ordinary manner.
At the end of the measuring roller is an apparatus to act on the bar d and stop
the machine when 50 or other definite number of yards have been wound on the
beam.
These improved self-acting stop motions instantly stop the machine when an end
breaks, and they dispense with the ordinary taking-up rods; one operative can
attend to several of these improved machines, as they are self-acting, and the
position of the broken yarn is always indicated by the raising of the end a¹ of the
piece a.
Having thus stated the nature of the Invention communicated to me by the
within named José M. Dalmau, I declare that I claim,
First. The improved warping machine, herein-before shewn and described, and the
apparatus for stopping the same when a yarn breaks.
Secondly. The small grooved pulleys B for dividing the warp, as shewn and
described.
And, Thirdly. The movable comb P, as shewn and described.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto set
my hand, this Eighth day of January, One thousand eight hundred and
seventy-eight.
