PROVISIONAL SPECIFICATION.
Improvements in or applicable to Traverse-warp, Taffeta, or like
Machines.
1, FRANCIS SUDBURY, of Market Street Works, Ilkeston, in the County of
Derby, Manufacturer of Hosiery and Gloves, do hereby declare the nature of this
invention to be as follows:-
:-
This invention relates to improvements in or applicable to traverse-warp,
taffeta, or like machines, and it has for its object to provide an improved automatic
weighting or tension device for the warp threads.
By the means about to be described the warp threads, passing from the bobbins
to the machine, receive the proper tension without the use of much weighting, and
these means also prevent the warp threads from vibrating and consequent crossing
on the T bar, as found heretofore, during the working of the machine.
This improved automatic weighting or tension device consists essentially of a tube
or roller, preferably of polished metal, which is placed in the angle formed by the
warp threads passing from the bobbin to the machine, and the bobbin itself. This
roller or tube will, by its own weight, bear against the warp threads and give
them the proper tension, it will further, by the slight friction caused and by
weighting the warp threads above the bobbin prevent the undesirable vibration of
the warp threads and consequent crossing on the T bar, and will thus tend to
produce a much improved fabric.
To prevent the roller or tube from shifting laterally, it is provided on both ends
with a small disc or flange each of which rests on the outside of the end discs of the
bobbin when the roller is placed in position.
The roller or tube being perfectly detached from the bobbin, or the machine, it
can easily, and with very little cost, be applied to any existing machine.
A further advantage in the use of this weighting or tension device is that the
weight placed in the weight boxes or cans of the bobbins can be greatly reduced,
and it has been found that the speed of the machine can thus be increased by
one third. The quality of the fabric to be produced can, therefore, be pre-
determined and regulated by regulating the weight in the weight box and
consequently the speed of the machine, an advantage which it has hitherto not
been possible to attain.

Improvements in or applicable to Traverse-warp, Taffeta, or like
Machines.
I, FRANCIS, SUDBURY, of Market Street Works, Ilkeston, in the County of
Derby, Manufacturer of Hosiery and Gloves, 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, reference being
had to the accompanying drawings and to the letters and figures marked thereon,
that is to say :-
My invention relates to improvements in or applicable to traverse-warp taffeta
or like machines, and it has for its object to provide an improved automatic
weighting or tension device for the warp threads.

page_text: By the means about to be described the warp threads passing from the bobbins
to the machine receive the proper tension, without the use of much weighting
and the warp threads are also prevented from vibrating and consequent crossing on
the bar as found heretofore, during the working of the machine.
This improved automatic weighting or tension device consists essentially of a
tube or roller preferably of polished metal which is placed in the angle formed by
the warp threads, passing from the bobbin to the machine and the bobbin itself. This
roller or tube will, by its own weight, bear against the warp threads and give them
the proper tension; it will further, by the slight friction caused, and by weighting
the warp threads above the bobbin, prevent the undesirable vibration of the warp
threads and consequent crossing on the T bar and will thus tend to produce a much
improved fabric. To prevent the roller or tube from shifting laterally it is pro-
vided at both ends with a small disc or flange, each of which rests on the outside of
the end discs of the bobbin when the roller is placed in position.
The roller or tube being independent of the bobbin and the machine it can easily
and with very little cost be applied to any existing machine.
A further advantage in the use of this weighting or tension device is that the
weight placed in the weight boxes or cans of the bobbins can be greatly reduced,
and it has been found that the speed of the machine can thus be increased by a
third or more.
The quality of the fabric to be produced can therefore be pre-
determined and regulated by regulating the weight in the weight-box, and
consequently the speed of the machine, an advantage which it has hitherto not
been possible to attain.
And in order that my invention may be readily understood, I proceed to describe
the same fully with reference to the accompanying drawings.
Figs. 1 and 2 are side and end views respectively of my improved tension
device, a being the roller or tube of polished brass, or other metal, and 6 the discs
or metal flanges to prevent lateral movement of the roller while resting on the
bobbin.
Fig. 3 shows the position in which the roller is placed with respect to the
bobbin c and warp threads d. When it is desired to increase or regulate the weight
of the roller or tube, I employ a weight carrier formed preferably of wire bent to
the shape shown in Figs. 4 and 5. This wire weight carrier consists of two arms e, e,
bent at f so as to form projections capable of being sprung into or made to enter
the tube or roller. In order to avoid confusion, one of the arms is not shown in
Fig. 5.
The ends of the wire are bent as shown at g so that they may prevent the
warp threads spreading and becoming dirty by friction against the portion of the
roller or tube which is close to the flange or disc where a little dirt may collect.
The arms e, e, are formed with a stem h of twisted wire bent into a hook to carry
weights, or box or receptacle for weights.
Fig. 6 represents the roller or tube a with the weight carrier of twisted and
bent wire and the weight box in the position they would occupy when applied to a
machine of the class hereinbefore mentioned. The roller rests in the angle between
the warp threads and bobbin discs as shown at Fig. 3, and the warp threads pass
between the two arms of the carrier, the arms being bent as seen at Fig. 5 so as
to clear the warp threads. The box or receptacle for weights j is attached to the
carrier by a central wire hook i or in any other suitable manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I.
claim is :-
1. A tension device for traverse warp taffeta, and similar machines, consisting
of a flanged tube or roller suitable weighted and adapted to rest against the warp
threads and bobbin, substantially as described.
2. The improved automatic weighting or tension device consisting of a tube a
having end flanges b, wire weight carrier formed with projections f adapted
to enter and be supported by said tube, bent ends g to prevent spreading

page_text: of the threads, and hooked end for supporting the weight box j, as described
and shown.
3. My improvements applicable to traverse warp taffeta and like machines as
herein before described and illustrated by the drawings.
