Improvements in or connected with Loom Lathes and
Shuttle Boxes.
We, THOMAS MOORE, of 34 Whalley Road, Gentleman, and SAMUEL
NUTTALL, of 24 Whalley Road, Storekeeper, both in Shuttleworth, near Bury, in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the lathe sword in looms employed in the manufacture
of calico and like fabrics. The object of this invention is to minimise the power
required to drive said looms by reducing friction in the working parts.
We attain this object by reducing and distributing the weight in the manner
hereinafter described and as illustrated in the accompanying sheet of drawings,
which represents a transverse section of the swing frame of a calico loom with our
invention applied. In looms such as herein before described, the lathe sword has
hitherto been formed with the upper and lower ends in the same plane.
In our invention, in order to reduce the strain on the main shaft, we construct the
lathe sword a to which the swing frame g is attached, of a bent form at the upper
end a', which thereby causes the shuttle box and the hand rail c to be placed at
an angle. By these means the weight is distributed so that the lathe sword is more
equally balanced, thereby causing less strain and friction on the main shaft.
We construct the shuttle box back of a bevelled form as shown on drawing.
In lieu of the cast metal shuttle guide hitherto employed, we reduce weight by
constructing a light steel guide such as f for use in combination with the shuttle
box; said guide may be produced by stamping or pressing under a steam hammer
or a hydraulic press or like means.
The pin connecting the latha sword a to the crank arm e, which has hitherto
been made of small diameter and thereby soon becomes loose by wear, we increase
to a size that will prevent vibration, with the result that the working parts will
wear longer, and the shuttle will travel with increased velocity.
The loom will by these means be enabled to travel quicker and require less power
for driving.

Improvements in or connected with Loom Lathes and
Shuttle Boxes.
We, THOMAS MOORE, of 34 Whalley Road, Gentleman, and SAMUEL.
NUTTALL, of 24 Whalley Road, Storekeeper, both in Shuttleworth, near Bury, in
the County of Lancaster, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This invention relates to improvements in the construction of the lathe sword and

The object of this invention is to minimise the power required to drive said
looms, by reducing and distributing the weight so as to lessen the friction in the
working parts.
We attain this object by the means hereinafter described, and as illustrated in
the accompanying two sheets of drawings, in which
Fig. 1 represents a transverse section of the swing frame of a loom with our
invention applied:
Fig. 2 is a front view of a part of said frame:
Fig. 3 is a front view, and Fig. 4 is a plan of the shuttle guide constructed
according to this invention :
Fig. 5 is a transverse section of the same on line A. A drawn to an enlarged
scale,
Fig. 6 is an end view of a loom constructed with the several parts arranged
according to our invention, and
Fig. 7 is a section of swing frame showing the position of the reed g' when the
lathe sword is in the position shown in Fig. 6.
In these views similar letters refer to similar parts.
In looms such as herein before named, the front part B of the lathe sword has
hitherto been formed with the upper and lower ends a¹ and a' in the same plane;
in this our invention in order to reduce the strain on the main shaft, we construct
the lathe sword a with the upper part a¹ to which the swing frame y is attached,
bent over at an angle inwards towards the crank shaft h, which thereby causes the
shuttle box and the hand rail c, to be also placed at an angle relatively with the
face of the lathe sword.
We fit the rocking shaft or pivot k to which the lower end of the lathe sword is
attached, to the loom frame a at such distance from the front part of said loom
frame as will cause the upper end a' of the lathe sword to be in a vertical position
when the crank is at the top, the weight j' on the flywheel at the bottom, and
the reed within a short distance of bumping, and which will at that time be in a
vertical position.
By these means the centre of gravity is placed directly over the rocking shaft or
pivot by which the lathe sword is supported, and the weight is more equally
distributed and balanced.
We construct the shuttle guide f by stamping and, or, pressing a plate of steel,
by any of the means ordinarily employed for producing stamped or pressed
articles, so as to obtain a light guide of a section such as is represented in Fig. 5,
and by these means dispense with the heavy cast metal guide hitherto in use.
In order to prevent the pin d working loose in consequence of the small diameter
of pins such as have been hitherto employed, we construct said pin of a size
corresponding to the size of the crank ', which thereby prevents vibration.
By these means the working parts will wear longer, the loom and the shuttle will
travel with increased velocity, and less driving power will be required.
°
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is: :―
1st. In looms that are employed for the manufacture of calico and like fabrics,
the construction of the lathe sword with the upper part bent inwards towards the
crank shaft, and the swing frame placed at an angle, in the manner and for the
purpose substantially as herein before described.
2nd. In looms that are employed for the manufacture of calico and like fabrics,
the use of a shuttle guide that is obtained by stamping and, or, pressing a plate of
steel by any of the ordinary means, for the purpose substantially as herein before
described.

page_text: 3rd. In looms that are employed for the manufacture of calico and like fabrics,
the arrangement and construction of the lathe sword in combination with the swing
frame, shuttle guide, connecting rod pin and fly wheel balance weight, substantially.
as, and for the purpose herein before described.
