1, HENRY BERNOULLI BARLOW, of the City of Manchester, Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR WEAVING. WARPING. SIZING. AND DRESSING," a communication to me
from abroad by Hyppolite Victor Hermite, Esquire, of Paris, in the Empire
of France, to be as follows:-
The object of this Invention is to separate cach warp thread from its
adjoining warp threads previous to passing through the healds (when they
required), and to give notice or to arrest the machine when any of the warp
threads adhere together.

to-and-fro motion to one or more rods, by which the warpis divided; this rod is
supported on part of the frame of the machine; a lever bears against each end
of the rod, and one of these levers is connected by a string or link to an elbow
lever with a bell on one arm. When the rod is displaced by any of the warp

the lay of the loom, or by any other moving part of the machine for weaving,
warping, sizing, and dressing, to which the improved apparatus is applied.
Or when the rod is displaced the lever acts on the ordinary stop rod to move
the driving strap from the fast to the loose pulley.
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 4th February 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of the City of Manchester, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of August, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Bernoulli Barlow, Her special license that I, the said
Henry Bernoulli Barlow, my executors, administrators, and assigns, or such
others as I, the said Henry Bernoulli Barlow, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thercafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN MACHINES FOR WEAVING, WARPING, SIZING, AND
DRESSING," a communication to me from abroad by Hyppolite Victor Hermite,
Esquire, of Paris, in the Empire of France, upon the condition (amongst
others) that I, the said Henry Bernoulli Barlow, my executors or adminis-
trators, by an instrument in writing under my, or their, or one of their hands
and seals should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the

page_text: same to be filed in the Great Seal Patent Office within six calendar montlıs
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, thatI, the said Henry Bernoulli Barlow,do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement (that is to say):
:-
The object of this Invention is to separate each warp threads from its
adjoining warp threads previous to passing through the healds, and to give
notice or to arrest the machine when any of the warp threads adhere
together.
.
. In machines of the present construction the warp is divided by stationary or
loose lease rods. Now this Invention consists in giving an oscillating or
to-and-fro motion to one or more rods, by which the warp is divided. This
rod is supported on part of the frame of the machine; a lever bears against
each end of the rod, and one of these levers is connected by a string or link
to an elbow lever, with a bell on one arm. When the rod is displaced by any
of the warp threads adhering together, the bell is brought into position for
being struck by the lay of the loom, or by any other moving part of the
machine, for weaving, warping, sizing, and dressing, to which the improved
apparatus is applied. Or when the rod is displaced the lever acts on the
ordinary stop rod to move the driving strap from the fast to the loose
pulley.
And in order that this Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 represents a section of part of a loom of the ordinary construction
to which the improvements are applied; Figure 2 is a front view of the same;
Figures 3, 4, aud 5 are detached views of portions of the imporved
machinery.
In Figure 1, A, A', are two warp threads placed near each other, which,
after passing alternately over and under the lease rods B, B1, pass through the
eyelet holes a, a', of the healds L, L', which are worked up and down, as
usual, and the warp threads are united at the point 2, where the cloth or
fabric begins. The lease rod B' is a fixture, as usual, whereas the lease rod B
shewn in section in Figure 3, and in elevation by dots in Figure 2, is made to
oscillate on its trunnions b, b', by the levers B2, B3, actuated by the links T, T,
the lower ends of which are connected to the lever of the weft stop motion, or
to the treadles, or to any other suitable moving part of the loom. The action
..

page_text: of tho links T, T¹, and consequently that of the lease rod B, can be regulated
according to the opening required in the warp for separating the threads
adhering together. The trunnions b, b1, bear upon the flat polished surface of
the brackets s, s', fixed to the frame sides of the loom ; they are surrounded
by a cord passing over a guide pulley P, loose on the axle of the roller P', to
which cord a weight is suspended, the trunnions 6, 6, are thus held against
the uprights 8, s', as long as the warp threads are disengaged from each other,
but when they are not disengaged the trunnions are drawn forward; this
forward motion of the trunnions constitutes the chief part of the Invention.
It will be evident that the details and dimensions may be varied. The lease
rod B and the levers B2, B3, may be worked by the batten or by the healds.
The Invention may be modified, as shewn in Figure 5, where two lease
rods B, hinged together, are employed for acting on the warp threads, or, as
shewn in Figure 4, where the moveable lease rod B is placed in the same
opening of the warp as the ordinary lease rod B'; or if several of the methods
shown are combined to act on several parallel lines of warp throads, or instead
of giving a vibrating motion to the rod B, a rotary or a to-and-fro motion may
be given, all or any of these modifications may be used, as the result would be
the same, namely, to produce a simultaneous or successive self-acting motion
to the warp threads.
When the moveable or ordinary lease rod has been displaced by the
adhering of the warp threads, notice is given to the weaver in the following
manner A bell K¹ is fixed to the end of the elbow lever K, O, K¹, sup-
ported on the stud 0; a cord is connected at one end to the lever K, and
at the other to the lower arm of the lever F, D, E. The brackets S, S',
support the shaft D, D', to which are fixed the levers F, D, E, and D', E',
see Figure 2; the ends of these levers bear against the trunnions b, b¹;
therefore if the trunnions are drawn forward by the adhering together of the
warp threads, this motion will be produced in the reverse direction at the
point F; the cord fis thus drawn to raise the bell Z, which will be struck
at every advance of the batten by the piece N hinged at o'. The stud O is
shewn fixed to the ordinary spring starting lever; if it should be requisite to
stop the loom when the warp threads adhere together, the piece N is fixed to
the batten, and comes in contact with the end of the lever K, O, K¹, when
the rod K has been raised, as above described, thus releasing the spring
starting lever from its retaining notch. By making the end K' sufficiently
heavy, the pulley P and weight p may be dispensed with, and roilers may be
applied to the trunnions b, b', to reduce the friction.

page_text: The above improvements are equally applicable to machines for warping,
sizing, and dressing yarns.
Having thus stated the nature of the Invention as communicated to me by
Hyppolite Victor Hermite, and the manner of performing the same, I-declaro
that I claim the self-acting lease rods shewn and directed for opening tho
warps, and the mechanism for giving notice or for stopping the machine when
the warp threads adhere together.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, the Third day of February, in the year of our
Lord One thousand eight hundred and sixty-three.
