Improvements in Apparatus for Splitting or Subdividing Warps.
I, WILLIAM ASHWORTH Manager of the Castleton Cotton Spinning and Manu-
facturing Company Limited, Globe Mill, Heywood, near Manchester, 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 has for its object the splitting dividing or subdividing of large
bundles of warp into warps of a smaller number of ends, and thus doing away with.
a considerable amount of manual labour and expense.
Hitherto in warping it has been customary to dye the bundles of warps and
where these consist of a large number of ends or warp threads it is often the case
that these bundles are not for the time being, wantel but that on the other hand
warps of a lesser number of ends may be required for the work in hand. When
this is the case the large bundles of warp are stored and it becomes necessary to
specially warp, or prepare a warp of the required number of ends or threads.
Sometimes a large number of these small warps may be wanted and when this is
the case a great amount of time and labour is expended in their preparation.
My invention is designed to overcome these defects and to provide apparatus
whereby the larger bundles of warp may be split or subdivided into smaller warps of
equal or unequal number of threads and thus do away with a large amount of hand
labour.
The invention will be fully described with reference to the accompanying drawings
in which:-
Fig. 1 is a side elevation of the splitting apparatus,
Fig. 2 a plan of same.
Fig. 3 a partial end elevation showing strap-fork arrangement, and
Fig. 4 is a plan of same.
In carrying out the invention a large bundle of warp is taken after the dyeing
process and placed on the floor of the warping room. The end is then led round
tension bars A fixed in a frame a at some distance from the main portion of the
frame, in order that a suitable amount of drag may be put upon it. In some cases I
dispense with the tension bars entirely. From these bars it is thence passed
through eye brackets B fixed to the floor, or it may be a comb, in a divided or
split condition. That is to say the large bundle of warp is subdivided into a .
number of smaller warps of an equal or unequal number of threads according to
requirements and each of these smaller warps is passed through the eye of one of
the brackets B. From thence the warps are passed over a comb consisting of a
number of pegs e fixed in a bar C; this comb still keeping the warp in a divided
condition. They are then conducted over a guide roller e' under a larger roller c
over which is journalled a roller and between the two latter. Still passing
forward they are conducted between one or more sets of rollers D in the manner
shown and into the cans, boxes, or other receptacles E, one of which is provided for
cach small warp. These cans are preferably provided with lids so that when the
whole lengths of warps have coiled themselves in the lids may be shut and the cans
taken from place to place without fear of the warps falling out.
It will be seen that the top rollers of all the pairs are simply placed loosely in
the slots of the bearing brackets but it must be understood that they may if desired
be caused to press with more or less pressure upon the warps passing through or
between them, by means of springs or weights and that instead of continuous
rollers a number of short rollers may be employed. By passing the warps between
the rollers I obtain a mangling action which is beneficial to the warps.

page_text: Instead of leading off the warps from the last pair of rolls, some may be led off
into cans placed under the first or second pair.
The machine is actuated from the pulleys F by straps cords or chains in the
manner shown whilst a strap fork arrangement is provided consisting of rods f¹
and levers one of the rods being so placed that the strap may be put on or off
the loose pulley when the operative is standing anywhere between the tensión
rods A and the comb bar C.
"I consider that by my invention much labour is saved as one person may sub-
divide a large warp where formerly it has been usual to employ three or four or to
specially warp the warps required which is a still greater source of expense. The
invention also entirely does away with the practice of storing warps.
I may remark that the details of the invention may be varied without departing
from the nature of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The method of splitting or subdividing a large warp consisting in passing the
said warp through one or more combs and thence through one or more pairs of
rollers into suitable receptacles substantially as described.
2. Apparatus for splitting or subdividing large warps consisting of one or more
combs, one or more series of roilers and receptacles and with or without a tensional
arrangement substantially as described.
3. Apparatus for splitting or subdividing large bundles of warps substantially as
described and shown with reference to the accompanying drawings.
