Improvements in Driving Tapes suitable for Cap and Ring Frames.
1, WILLIAM KITSON BLACKBURN, of Phoenix Mill, Brighouse, in the County of
York, Cotton Spinner, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object, the construction of tapes used for driving the
bobbins on cap and ring spinning and twisting frames in such a manner that, the
edges of the tapes will not fray, or be injured so readily by the constantly changing
positions of the wirls in relation to the driving cylinder as is the case with tapes
constructed in the usual manner.
In carrying out my invention, the driving tape may be woven in the manner as
hitherto by an ordinary machine, but instead of making the warp threads of an equal
thickness throughout, I arrange those warp threads in the centre of the tape, and for
some distance on each side thereof, considerably thicker than those at and near to
cach edge; by which means, the tape when woven, is thickest in the middle, and
when at work, takes the strain off the edges, which are more flexible than the centre,
and thus allowing for the constantly changing angle between the driving cylinder
and wirls.

COMPLETE SPECIFICATION.
Improvements in Driving Tapes suitable for Cap and Ring Frames.
I, WILLIAM KITSON BLACKBURN, of Phoenix Mill, Brighouse, in the County of
York, Cotton Spinner, 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 construction of tapes used for driving the
bobbins on cap and ring spinning and twisting frames in such a manner, that the
edges of the tapes will not fray or be injured so readily by passing over the tension
pulleys, and by the edges coming in contact with the flanges of the whirls in
consequence of the latter constantly changing their position in relation to the driving
cylinder, as is the case with tapes constructed in the ordinary manner.
In carrying out my invention, the driving tape may be woven in the manner as
hitherto by an ordinary machine, but instead of making the warp threads of an equal
thickness the entire width of the tape, I arrange those in the centre and for some
distance at each side thereof, to be considerably thicker than those at and near to each
edge, by which means, the tape when woven is considerably thicker in the middle for
some portion of its width than at the edges; thereby making the edges more flexible
than the centre part which receives the major portion of the strain.
By forming a narrow-strip at each edge of the tape with warp threads thinner than
those used in the centre, the edges bend freely when running in contact with the
flanges at the time the whirls are at or about the termination of the top and bottom
portion of the traverse thus allowing for the constantly changing angle between the
driving cylinder and whirls without materially injuring the edges of the tapes by
coming in contact with the flanges of the whirls.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is: :-
warp
Driving tapes constructed with a longitudinal strip in the centre having the
threads considerably thicker than those at the edges for the purpose as hereinbefore
set forth.
