IMPROVE- MENTS IN LOOMS FOR WEAVING AND IN APPARATUS CONNECTED THEREWITH
Year: 1875

page_text: LETTERS PATENT to William Haggas and John Haggas, Spinners
and Manufacturers, of Ingrow and Oakworth Mills, near Keighley,
in the County of York, for the Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said William Haggas and
John Haggas at the Office of the Commissioners of Patents, with
their Petition, on the 30th April 1875.
We, WILLIAM HAGGAS and JOHN HAGGAS, Spinners and Manufac-.
turers, of Ingrow and Oakworth Mills, near Keighley, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN LOOMS FOR WEAVING AND IN APPARATUS CONNECTED THEREWITH," to be
as follows, that is to say :-
Our Invention relates to employing a self-acting apparatus for taking
off the pressure or tension of the warps as the weaving operation takes
place; also in delivering the warps at any required tension or pressure,
producing an even fabric and preventing the warps from twisting and
stretching. For this purpose we fit a worm wheel on the end of the

page_text: warp beam (or we may fit a worm wheel and gear on each end of the
warp beam); the worm wheel actuates a small wheel fitted on the top of
an upright shaft, giving motion to a small bevil wheel fitted on the other
end of the upright shaft. This bevil wheel actuates another small bevil
wheel fitted on a stud which is made to revolve with the wheel. One
end of this stud works in a bearer fitted to the loom frame; the other
end is made with a jaw in which fits the head of a screw. The screw
is made the length of the weighted lever and works through a boss cut
with a female screw; the boss is formed on a slide having a weight
attached to it. The slide moves on a long lever which is fitted in a
bearer bolted to the loom frame; the upright shaft works in bearers also
fitted to the loom frame. The worm wheel turning as the weaving opera-
tion takes place causes the small wheel and bevil wheels to revolve slowly,
turning the screw, bringing forward the slide and weight, taking off the
pressure or tension.
On the end of the weighted lever, near the fulcrum, is fitted a bracket
in which fits a small barrel having a ratchet wheel fixed thereon. On
the barrel is attached one end of a rope, which rope is made to lap over
the end of the warp beam, and the other end is fastened to an eye bolt
fitted to the loom frame. On the weighted lever is fitted a pawl working
in the ratchet wheel, preventing the barrel moving when the required
pressure or tension is placed on the warps.
SPECIFICATION in pursuance of the conditions of the Letters Patent,

filed by the said William Haggas and John Haggas in the Great
Seal Patent Office on the 29th October 1875.

next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Haggas and John Haggas,
do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to
the Drawing hereto annexed, and to the figures and letters marked
thereon, that is to say :-
*
This Invention relates to employing a self-acting apparatus for taking
off the pressure or tension of the warps as the weaving operation takes
place; also in delivering the warps at any required tension or pressure
producing an even fabric, and preventing the warps from twisting and
stretching. For this purpose we fit a worm wheel on the end of the warp
beam (or we may fit a worm wheel and gear on each, end of the warp
beam); the worm wheel actuates a small wheel fitted on the top of an
upright shaft, giving motion to a small bevil wheel fitted on the other,
end of the upright shaft. This bevil wheel actuates another small bevil
wheel fitted on a stud, which is made to revolve with the wheel. One
end of this stud works in a bearer fitted to the loom frame; the other
end is made with a jaw in which fits the head of a screw; the screw
is made the length of the weighted lever and works through a boss cut
with a female screw; the boss is formed on a slide having a weight
attached to it. The slide moves on a long lever which is fitted in a
bearer bolted to the loom frame; the upright shaft works in bearers fitted
to a bracket fixed to the loom frame. The worm wheel turning as
the weaving operation takes place causes the small wheel and bevil

page_text: wheels to revolve slowly, turning the screw, bringing forward the slide
and weight, and taking off the pressure or tension.
On the end of the weighted lever near the fulcrum, is fitted a bracket
in which fits a a small barrel having a ratchet wheel fixed thereon. On
the barrel is attached one end of a rope which is made to lap over the
end of the warp beam, and the other end is fastened to an eye bolt
fitted to the loom frame. On the weighted lever is fitted a pawl working
in the ratchet wheel, preventing the barrel moving when the required
pressure or tension is placed on the warps.
But to enable our improvements to be better understood we will
proceed to more particularly describe the same by reference to the
accompanying Drawing, in which Figure 1 represents a back view of
a loom and front view of the apparatus; Figure 2, side view, and Figure 3
plan of the same. Similar letters of reference are used in all the
Figures to represent similar parts.
On the end of the warp beam A is fitted a worm wheel B which
actuates a small wheel C fitted on the top of an upright shaft D, giving
motion to a bevil wheel E, fitted on the other end of the shaft D. The
bevil wheel E actuates the bevil wheel F, which is fitted on a stud G
and made to revolve with the bevil wheel. The stud G works in a
bracket bolted to the loom stay I. The end of the stud G is made
with a jaw J, in which fits the head K of the screw L. This screw
works through a boss M formed on the slide N to which is fitted a
weight O. The slide N slides on the lever P, which is fitted in a
bracket Q, bolted to the loom frame.
On the fulcrum end of the lever P are fitted brackets R in which
fits a barrel S having a hook T fitted thereon, on which is placed
one end of a rope U, which is made to lap over the end of the warp
beam A; the other end of the rope is fastened to an eye bolt V,
fitted in the stay I of the loom. The rope is for the purpose of giving
the required pressure or tension to the warps. On the stud of the
barrel S is fitted a ratchet wheel W, in which works a pawl X for pre-
venting the barrel moving when the required pressure or tension is
applied on the warps. To give or take off the pressure a key is placed on
the square end Y of the stud of the barrel S, and by turning the ratchet
wheel gives or releases the pressure on or tension of the rope U. The
upright shaft D works in brackets Z, formed on a bearer A¹ fitted to a

page_text: bracket B¹. The worm wheel B turning as the weaving operation takes
place, causes the wheel C and bevil wheels E and F to revolve slowly,
turning the screw L, bringing forward the slide N and weight O, slowly
taking off the pressure or tension on the warps C¹. A worm wheel is
also fitted on the other end of the warp beam A and an eye bolt V to
allow the fitting of the apparatus on either side of the loom, and an
apparatus can be fitted on each side of the warp beam. A key is used
to fit on the square end D' of the screw L to bring back the slide N and
weight O, when they have travelled the length of the screw or finished
the warps.
Having thus described our improvements and the best means we are
acquainted with for carrying the same into effect, we would have it under-
stood, that we do not confine ourselves to the precise details shewn and
described, as they may be varied without departing from the peculiar
character of the Invention, but what we do claim is, the general
arrangement and construction of the apparatus for taking off the
pressure or tension on the warps as the weaving operation takes place,
substantially as herein-before described and represented in the accom-
panying Drawing.
In witness whereof, we, the said William Haggas and John Haggas,
have hereunto set our hands and seals, this Twenty-fifth day
of October, in the year of our Lord One thousand eight hundred
and seventy-five.
