PROVISIONAL SPECIFICATION.
Machinery for Making Warps.
We, WALTER TWISS GLOVER, of the firm of Walter T. Glover & Co., Engineers,
of Bridgewater Street Iron Works, Salford, in the County of Lancaster, and WILLIAM
EDMONDS SAN GARDE, in the employ of the said firm, and of Accrington, in the
said County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is more particularly to provide means for making
warps such as
are used in looms for weaving purposes or those employed for
making ropes or cords or those otherwise used the said warps being composed
of a number of ends of yarn or fibrous or other material up to several thousands
as is the case especially with cotton warps.
According to our invention we arrange two or more lines of shafting to run
parallel to or at an angle with the table or creel or other machinery carrying
the yarn or fibrous or other material, in some cases in cops in others on bobbins or
hanks or otherwise and from which the ends of the yarn intended to compose the
warps are to be supplied.
Where two lines of shafting are used one of the said shafts is suitably driven
in the ordinary way by a pulley or pulleys & straps from a main driving shaft,
& the other shaft is stationary or otherwise according to circumstances.
On
the front shaft a number of fluted rollers are fitted corresponding with the
number of warps the machinery is required to make at one time.
On the back shaft are fitted roller carriers which carry an equal number of rollers
to those on the front shaft. These are covered with flannel or india rubber or some
other tenacious or elastic substance & they rest by their weight & that of part or
the whole of the weight of their holders on the front shaft rollers.
The back shaft rollers run loose on short shafts or studs fastened in their holders
so that when the front shaft rollers which are fixed on their shaft are caused to
revolve by the revolution of their shaft they in turn cause the loose running rollers
above them also to revolve & by this means the ends of yarn or material composing
the warps & which are passed between the top & bottom rollers are drawn through
whereupon the said warp by its own gravity falls into a skip placed below to receive
it or it is wound on a bobbin or crcel or other suitable receptacle intended to receive
it. Where the top roller is required to press very heavily on the bottom roller
a spring is suitably attached to the top roller carrier & the other part of the
machinery to increase the pressure of the said top roller on the bottom one.
Moreover there is sometimes a third line of shafting used, partly to bind the
parts of the machinery together & partly to assist the tension on the yarn by
passing the yarn from the rollers back to the said shafting either under or
over on small pulleys carried on the said shaft & thence again to the rollers as
often as may be found necessary. There is also a suitable arrangement of hand
lever or levers connected with each head or system to enable the warper at once
to stop the drawing through of the warp, when desired in consequence of the
breaking down of any of the ends or other cause.
Furthermore the whole is supported by a suitable framework arranged to meet
the exigences of the case. Where it is found desirable or necessary an extra shaft
& rollers are used & the rollers & shafts are driven by being geared one with the
other as well as by pulleys & straps or bands.

Machinery for Making Warps:
We, WALTER TWISS GLOVER, of the firm of Walter T. Glover & Co., Engineers,
of Bridgewater Street Iron Works, Salford, in the County of Lancaster, and
WILLIAM EDMONDS SAN GARDE, Manager at the said Works, of Accrington, in
the said County, 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 :-
The object of our invention is more particularly to provide means for making
warps such as are used in looms for weaving purposes, or those employed for
making ropes or cords, or those otherwise used, the said warps being composed
of a number of ends or threads of yarn up to two or more thousands as is the
case especially with cotton warps used for weaving cloth or for making cotton
ropes or a less number as in the case of warps for cloth or ropes of jute, hemp,
or other fibrous material.
For this purpose we arrange two or more lines of shafting A. A. Fig. 2, Sheet 1,
running parallel with the table or creel carrying the yarn or fibrous material of
which the warp is to be made. These shafts are carried on standards B. B.
Figs. 1 & 2 Sheet 1. or other suitable framework provided with suitable bearings
and stays. One of the shafts is driven in the ordinary way by a pulley or pulleys
and straps from a main driving shaft and the other shaft where two are used is
stationary or otherwise according to circumstances. On the front shaft one or more
fluted rollers D Fig. 2 Sheet 1, & Figs. 3 & 6 Sheet 2 are fitted corresponding with
the number of warps the machinery. is required to make at one time and on the back
shaft are fitted roller carriers E Fig. 1, Sheet 1, and Figs. 3 & 5, Sheet 2, carrying
an equal number of rollers F Fig. 1, Sheet 1, & Figs. 3, 4, 5 Sheet 2, to those on
the front shaft. These rollers Fare covered with flannel, india rubber or some other
tenacious or elastic substance and they rest with the whole of their own weight and
part of the weight of their carriers on the bottom rollers.
Morcover the rollers I run loose on short shafts fastened in their holders so that
when the front shaft rollers which are fixed on their shaft are caused to revolve by
the revolution of their shaft they in turn cause the loose running rollers above them
also to revolve and by this means the ends of yarn composing the warp and which
are passed between the top and bottom rollers are drawn through and the warps
either are allowed to fall by their own gravity into skips or other vessels placed to
receive them as is the case when used on ropewalks, or they are wound on to a
bobbin or drum G Figs. 1 & 2 Sheet 1 as when used on a machine for making ropes
or on a loom.
When the top roller is required to press very heavily on the bottom roller a
spring H Fig. 1 Sheet 1, & Figs. 3 & 5 Sheet 2, is suitably attached to the
top roller carrier E and to some other part of the machinery to increase the
pressure. Sometimes a third line of shafting is used partly to bind the parts of
the machinery together and partly to increase the tension on the yarn by passing
it from the rollers back to the said shafting either under or over on small
pulleys carried on the said shaft or otherwise and thence again to the rollers
as often as may be found necessary. The third shaft 1 Fig. 3, Sheet 2 is specially
useful when there are several heads of warping in one continuous line along the side
of a long room or otherwise as it then being fixed to the several standards carrying
the heads, tends to bind them together, moreover as aforesaid it carries the pulleys L
Fig. 2, Sheet 1 & Fig. 6, Sheet 2, over which the warp is passed from between the
top & bottom roller and back again to the rollers one or more times in order to
increase the tension on the yarn and bring them all forward uniformly, thereby
preventing slack places in the warp which is apt otherwise to be the result when a
large number of ends are being warped. There is also a suitable arrangement of
hand lever or levers K Figs. 3, 5 & 6 Sheet 2 where there is more than one head of

page_text: warping, connected with each head or system to enable the warper to at once stop
the drawing through of the warp when desirable in consequence of the breaking
down of the ends or some other cause such as when the warp is finished or a
sufficient length has been run through or it is otherwise desirable to stop the head.
This is done by pushing back the hand lever or levers and engaging it by means of
notches O Figs. 3 & 5 Sheet 2 with the shaft I Figs. 3 & 6 Sheet 2 and thus raising
the roller carrier E, & separating the top from the bottom roller whereupon the
warp is no longer drawn through.
When, as referred to above, the warp is passed from the roller D to the pulley L
and back gain one or more times, instead of being passed over the pulley L and
thence to the drum G Figs. 1 & 2, Sheet 1 as shown in the drawing Fig. 1, (Sheet 1)
it may be and generally is, passed under and then over the pulley L and taken
thence back over the roller D and again in the same way, as often as may be
desired, from the roller D to the pulley L and back to the roller D and finally
from D town to the drum G, or into a skip into which it falls by its own gravity.
Furthermore the general arrangement of the framework is adapted to the
exigencies of the particular case to which it is to be applied. Where necessary or
desirable an extra shaft M and roller N Fig. 4. Sheet 2. are used and the shafts
are driven by being geared P the one with the other instead of or in addition to the
manner aforesaid. This is specially desirable where a heavy warp has to be made
and extra pressure is required as well as for the positive driving of the rollers in
order to avoid slippage.
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 use and application of the fluted and covered rollers D and F to draw
the ends of yarn to make a warp acting substantially in the manner and for the
purposes aforesaid and illustrated in the drawings hereunto annexed, Figs. 3 and 5.
Sheet 2.
2 The arrangement of the pressure spring and the knock off lever arranged to
act substantially in the manner and for the purposes herein before described and
illustrated in the drawings hereunto annexed, Fig. 1. Sheet 1, and Figs. 3 & 5,
Sheet 2.
3° In the manufacture of warps the arrangement and construction of apparatus
or machinery hereinbefore described and illustrated in the drawings annexed
substantially in the manner and for the purposes described.
