PROVISIONAL SPECIFICATION.
Improvements in and relating to Warping and Means for Preventing
the Threads of the Chain or Warp becoming Entangled.
We JOHN GARSTANG and JAMES BANCROFT both of Millstead Mills, Todmorden,
in the County of York, Manufacturers, do hereby declare the nature of this invention
to be as follows:-
In this invention of improvements two or more beams of yarn are arranged similar
to those of a tape machine. The chain or sheet of yarn from the first is conducted
over a guide roller and under a falling roller to take up slack yarn the result of over-
running. The chain or sheet of yarn on the next beam passes over a similar guide
and falling roller as the first, and so on through the rest of the beams. The several
sets of rollers being elevated one above another to keep the sheets of yarn apart from
each other. We would observe that we prefer a "lease" to be taken in the yarn of each
beam before being placed in the machine.
A lease band is drawn through the lease of the several chains of yarn forming one
warp which is caused to pass over and between, or partially around and between two
or more grip-rollers. These rollers perform the actual work of drawing the yarn over
the conducting or guiding rollers and delivers it by preference in a bag.
To contract the several sheets of yarn, before passing the gripping rollers, each
sheet is drawn through a suitable hook or eyelet; and to prevent the threads of the
warp from becoming entangled with each other, after leaving the machine, a thread
from a bobbin is wound round the warp in a spiral manner either before or after
leaving the machine. The bobbin being carried round the warp by suitable mechanism,
for this purpose, whilst the warp is in motion.

COMPLETE SPECIFICATION.
Improvements in and relating to Warping and Means for Preventing
the Threads of the Chain or Warp becoming Entangled.
We, JOHN GARSTANG and JAMES BANCROFT, both of Millstead Mills, Todmorden, in
the County of York, Manufacturers, 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 :-
In this invention of improvements, two or more beams of yarn are arranged in
position similar to those of a tape-machine. The sheet of yarn from the first is
conducted over a guide roller and under a falling roller to take up slack yarn. The
sheet of yarn from the next beam passes over a similar guide and falling roller as the
first, and so on with the rest of the beams; the several sets of rollers being elevated
one above another to keep the sheets of yarn apart from each other.
A lease may be taken of the yarn of each beam before being placed in the machine,
and a lease band drawn through the lease of the several chains of yarn, forming one
warp, which is caused to pass over and between, or partially around and between, two
or more grip rollers. These rollers perform the actual work of drawing the yarn over
the conducting or guiding rollers, and deliver it by preference in a bag. To contract
the several sheets of yarn before passing the gripping rollers, each sheet is drawn
through a suitable hook or eyelet; and to prevent the warp threads becoming
entangled with each other, after leaving the machine, a thread from a bobbin is
.

machine.
In the accompanying drawings,
Fig. 1 is a side view of the machine;
Fig. 2 an end view of the driving part of the machine; and
Fig. 3 a view of the rear end of the machine.
Fig. 4 is a plan of the apparatus for winding the thread spirally round the warp.
A is the framework of the machine, at the rear end of which is mounted a series of
back beams B. The warp or sheet of yarn from the first is conducted over guide-
rollers C and C¹, and under a falling roller D, mounted in brackets E, to take up
slack yarn.
The sheet of yarn or warp from the next beam passes over guide
rollers C and C¹ and under falling roller D, mounted in the brackets F, and so on with
the warp from the rest of the beams, which is conveyed in like manner over and under
rollers C, C and D, mounted on their respective brackets G, H and I.
The several sheets of warp threads are now conveyed to the hooks J, and are
supported during their passage by the sustaining rods or bars E¹, F1 G¹, H¹ and 1.
After passing the hooks J, the warp is then conveyed over guide roller K, and
through the centre of the revolving disc L, (which carries the thread bobbin M) and
over guide roller N, and is then drawn or carried forward by the draw rollers O and P;
the requisite grip or adhesion being imparted to the said rollers by the weighted
levers Q. A guide roller R, driven by an endless strap from pulley S, secured to the
shaft of the draw roller O, conveys the warp as it delivered from the draw rolls clear
of the machine; where it then falls into a bag, or other receptacle, prepared to
receive it.
The varying speed pulleys T and U may be employed to increase or diminish the
speed of the machine by shifting from one speed to another, in a manner well under-
stood, an endless belt (not shewn) which connects the upper and lower speeds T and U;
and to indicate the length of warp passing through the machine, a worm on the
shaft X drives toothed wheel W, which, revolving slowly, brings the pin secured to its
face, at each revolution, between the teeth of the dial-plate V, to the extent of one
tooth each revolution.
The several sheets of warp threads, passing from the rear part of the machine, are
contracted in passing their respective hooks J in chain form; after which a thread is
wound spirally round the warp to prevent entanglement of the warp threads, whilst
being transported from one place to another. For this purpose, the whole of the warp
threads pass through the centre of the revolving disc L, carrying thread bobbin M.
The disc is held freely in place by guide bowls L, L2 and L³, and is actuated by the
endless band or cord Y from pulley Z, secured to shaft X.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The combination of mechanism, operating in connection with two or more back
beams, substantially as described and illustrated.
2. The means for automatically winding a thread or cord spirally round the warp,
substantially as described.
