IMPROVEMENTS IN A MACHINE FOR INCREASING THE WIDTH OF WOVEN FABRICS
Year: 1885

page_text: I JAMES DYKES of Bury Ground, Bury, in the County of Lancaster, Engineer,
do hereby declare the nature of my invention for IMPROVEMENTS IN A MACHINE
FOR INCREASING THE WIDTH OF WOVEN FABRICS to be as follows:-
My Invention consists of a Machine in which the width of Woven Fabrics of
various materials may be increased at any period during the Bleaching, Dyeing,
Finishing or Printing of the same.
°
It consists of two frame sides carrying bearings in which is a bottom roller. A
top roller is placed immediately over the same, which top roller is hung in adjust-.
able bearings. These bearings are adjusted by means of screws, which are actuated
so as to secure the parallelism of. the roller by a shaft with two pinions gearing into
bevelled pinions keyed upon the ends of bearing screws. The rollers are fluted
into concentric grooves, those of the top roller being opposite the projections on the
bottom roller A carrier bar or rail is provided upon each side of the top roller for
the purpose of leading the cloth into the machine and delivering it out again in
the proper direction, Four pulleys are also provided on two bars for the purpose
of carrying an endless band running in recesses prepared in the fluting on top
roller, These pulleys and band are so adjustable as to be applied to any width of
cloth. This endless band is retained in position and kept in a state of tension by
means of a weight which is fitted with a grooved pulley hung upon the slack of
the endless band.
The operation of the machine is as follows The top roller being raised by
turning hand wheel of pinion shaft, actuates bevel wheels on screws of bearings
The bearings slide up the frame sides carrying up the top roller with them.
The cloth is then introduced and placed across the top roller the endless band
engaging the edges of the cloth. The machine: is now set in motion and the top
roller being lowered by the screws is pressed down upon the cloth. The edges
being retained in their original position by the endless band the projections on the
top roller are forced into the depressions on the bottom roller carrying the cloth
with them, the whole revolving at a considerable speed whereby the width of the
cloth may be increased as required.

I, JAMES DYKES of Bury in the County of Lancaster Engineer do hereby
declare the nature of my invention for IMPROVEMENTS IN A MACHINE FOR
INCREASING THE WIDTH OF WOVEN FABRICS and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
My. Invention consists of a machine in which the width of woven fabrics of
various materials can be increased at any period during the Bleaching, Dyeing,
Finishing and Printing of the same. It consists of two frame sides A, A, (sce
Drawings) carrying bearings B, B, in which is carried a bottom roller C, A top
roller D, is placed immediately over the same which top roller is hung in adjust-
able bearings E, These bearings are adjusted by means of screws F, which are
actuated so as to ensure the parallelism of the roller by a shaft G, with two
pinions H, gearing into bevelled pinions I, keyed upon the ends of bearing screws F,
The rollers are fluted with concentric grooves those of the top roller being opposite
the projections upon the bottom roller. A carrier bar or rail K, is provided upon
each side of the top roller for the purpose of leading the cloth into the machine and
delivering it out again in the proper direction. Four pulleys L, are also provided
on two bars M, M, for the purpose of carrying two endless bands N, N, running in
recesses prepared in the fluting on the top roller, These pulleys and bands are so
adjustable as to be applied to any width of cloth. These endless bauds are
retained in position and kept in a state of tension by means of a weight O which
is fitted with a grooved pulley P, hung upon the slack of the endless band. A
scrimped or fluted roller is also introduced as shown, driven by the pulleys R R
from the end of bottom roller for the purpose of further widening the cloth.
The operation of the machine is as follows:-The top roller Ď being raised by
turning the hand wheel S, of pinion shaft G, actuates bevelled pinions I, on screws
of bearings E E, the bearings slide up the frame sides carrying up the top roller
with them. The cloth is then introduced and placed across the top roller, the
endless band engaging the edges of the cloth.
The machine is now set in motion and the top roller being lowered by the screws
actuated by the pinions I, shaft G, and hand wheel S, is pressed down upon the
cloth. The edges being retained in their original position by the endless band, the
projections on the top roller are forced into the depressions on the bottom roller
carrying the cloth with them the whole revolving at a considerable speed whereby
the width of the cloth may be increased as desired.
Having now particularly described and ascertained the nature of my
invention and in what manner the same is to be performed, I declare here that
what I claim is
1st The method of expanding the cloth by means of grooved' rollers.

page_text: 2nd The elevation and depression of aforementioned rollers by means of
adjusting screws and hand wheels shaft and pinions.
3rd The retention of edges of cloth by means of endless ropes and weights.
4th The arrangement of adjusting to various widths of cloth.
And lastly the general arrangement of the machine for the purposes for which it
is to be used.
