WILLIAM GAINES BYWATER of Sweet Street Foundry Leeds in the County of
York, Machine Maker, and THOMAS BELLSHAW BEANLAND of 35 Temple Terrace
Beeston Hill, Leeds, in the County of York, Draughtsman do hereby declare the
nature of this invention to be as follows:-
The present improvement is adapted to machines, in which the warp is wound on
sections and is for the purpose of winding the warp on each and every section of the
complete warp with the saine tension and so obtaining more perfect uniformity in the
building of the warp upon the sections. For this object we propose to place a
moveable weighted roller between the retaining rollers (Patent No. 6427, 1886) and
the section upon which the warp has to be wound, in such a manner that the warp
operated upon shall be subjected to a constant weight or pull, so that if the warp
should be delivered by the retaining rollers in varying states of tension, or be taken
up by the section too quickly or too slowly, the weighted roller will immediately rise
or fall as the case may be, and so prevent irregular tension. The amount of weight
which may be put upon the roller may be varied so as to suit the different materials
operated upon.

Improvement in Warping Machines.
WILLIAM GAINES BYWATER, Sweet Street Foundry, Leeds in the County of York,
Machine Maker, and THOMAS BELLSHAW BEANLAND, 35 Temple Terrace, Beeston
Hill Leeds, in the County of York, Draughtsman 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 present improvement is adapted to machines in which the warp is wound on
sections, and is for the purpose of winding the warp on each and every section of the
complete warp with the same tension and so obtaining more perfect uniformity in the
building of the warp upon the sections. For this object we propose to place a
moveable weighted roller between the retaining rollers (Patent No. 6427, 1886) and
the section upon which the warp has to be wound, in such a manner, that the warp
operated upon shall be subjected to a constant weight or pull, so that if the warp
should be delivered by the retaining rollers in varying states of tension, or be taken
up by the section too quickly or too slowly, the weighted roller will immediately rise
or fall as the case may be and so prevent irregular tension.
The amount of weight which may be put upon the roller may be varied so as to
suit the different materials operated upon.
In order that this invention may be better understood and carried into practical
effect we have hereunto annexed drawings, of which the following is a description.
Fig. 1 is a side elevation of that part of a warping machine to which the present
improvement relates. Fig. 2 is a front elevation of the same. A is the framing, Bis
the section upon which the warp has to be wound at a uniform speed, which may be
accomplished by various methods but with the present invention the well known
method of friction plate C and moveable friction pulleys C₁ is used, the movement of
the friction pulleys (upon the face of the friction plate C, corresponding with the
movement of a presser pulley C³ which is operated upon by the warp as it is being
wound on the section B. D D are a pair of rollers which draw the warp from
bobbins, cops or any other source, and deliver the same towards the section B at a
uniform speed, the rollers DD are connected to the friction pulleys C₁ by means of
gearing. We do not confine ourselves to this particular form of mechanism for the
rollers D D as they may be arranged in various ways and still have the same purpose,
viz. the delivery of the warp at a uniform speed towards the section B. At any point
between the rollers D D and the section B is a horizontal roller E which is supported
at each end by bearings E in which it revolves freely. The bearings E¹ are fastened
to endless chains F which are carried upon chain wheels G. The wheels G are
fastened to a shaft G¹ the ends of which rest upon pulleys H, thus the shaft G¹ is free
to revolve and the chains F and roller E to move up or down. A weight J is fastened
to each chain upon which additional weights may be placed to suit the requirements
of the work being done. The chains F may be of any convenient length so as to give
space for the movement of the roller E.

page_text: The warp being delivered by the rollers D D instead of passing in a direct line or
nearly so towards the section B, is passed under roller K and in a vertical direction
to the roller E, round the same, and back again to roller K₁ then from this point direct
to the section B, thus the warp between the rollers K and K¹ is subjected to an
upward pull corresponding to the weights which are placed upon the chains F. In
the present illustrations the direction of the pull upon the warp is shewn as being
upwards, but the same result may be obtained by so arranging the mechanism that
the direction of the pull upon the warp may be downwards or horizontal. In order
to regulate the speed of the section B to correspond with that of the rollers D D we
have provided mechanism shewn at Fig. 3. L is the presser shaft upon which the
arm M is fastened, and which carries a wheel N in its forked end which forms a nut
on the screw N¹. The screw N is fastened to arm P which works loosely upon the
shaft L, and which carries runner studs R engaging between the flanges of the
friction pulleys C¹. Thus by turning the wheel N, the position of the friction pulleys (¹
upon the plate C may be altered, without altering the position of the presser
pulley C³.
It is found advantageous in working this invention so to regulate the speed of the
receiving section that the roller E descends slowly during the winding of the warp
upon the section, as it may be raised when necessary whilst the machine is in motion
by slightly releasing the grip of the friction pulleys C¹ upon the plate C, this is
accomplished by means of foot lever S which when pressed, lifts the weighted
lever T.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is :
The application of a moveable weighted roller to warp which passes from a delivery
to a receiving apparatus, in such a manner as to give a constant uniform tension or
pull to the said warp. Substantially as herein set forth and described.
