PROVISIONAL SPECIFICATION.
Improvements in Drawing Machinery for Preparing Fibrous
Substances.
GEORGE VICTOR PRIESTLEY Basinghall Street Chambers Boar Lane Leeds
Engineer, do hereby declare the nature of this invention to be as follows:-
An endless horizontal drawing leather in place of the vertical leather at present
used in drawing machines in conjunction with an endless flannel above. The lap or
sliver from the drawing machine being wound round the flannel to any desired
thickness.
The above improvement in no way affects the working parts of the gill drawing
machine before the fibre comes to the draught rollers, but when it emerges
therefrom the drawing leather on the bottom draught roller instead of being a short
one and working vertically, in the above improvement is made endless 40 feet or
more in length and supported in a horizontal direction by means of small rollers..
The leather is kept tight by means of heavy rollers underneath which sways down
the lower side of the leather band and so keeps the upper half on a horizontal
level.
Above this leather and driven by it (that is by friction or other means if
preferred) is a canvass or flannel band the same width as the leather, and kept taut
by a roller at each end.
The operation is as follows.
When the fibre appears thro' the draught roller, it dissapears between the flannel'
and leather band and emerges at the other end where the fibre is carried over &
back again by the canvass. When it reaches the entrance end again it is turned down
again and so continues its course, the lap or sliver always increasing in thickness
and weight as long as fibre is put thro' the gill machine. The leather and canvass.
can be made any length if the machine will drive it.

COMPLETE SPECIFICATION.
Improvements in Drawing Machinery for Preparing Fibrous
Substances.
GEORGE VICTOR PRIESTLEY Basinghall Street Chambers, Boar Lane Leeds
Engineer, 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 above invention is an attachment to any gill box drawing machine, in which
gills and fallers are used, and consists of a long endless belt (of any desired width)
and made of any suitable material, travelling in a horizontal position. It is
necessary that the fibre passing thro' the gill machine should be straightened and
laid even in lengths or "laps," such "laps" not being less than 50 feet in length
when opened out flat. For the sake of economy it is necessary that "laps" of
100 feet in length should be made.
It is usual to have a drum at the ends of such gill machines, about a yard diameter,
and the "laps" from such drums would only be about 10 feet long. To obtain laps
of 50 to 100 feet in length, a very large drum would be required, which would be
costly and unmanagable. To do away with this defect, I substitute the horizontal
travelling band, properly supported by framework and which band can be of

page_text: any length, and rotated from the gill machine, so that when the machine stops, the
other stops.
In the accompanying drawings,
Figure 1 is a side view of so much of a gill box machine as is necessary to shew
the application thereto of my invention.
Figure 2 is an enlarged view of same machine.
A is the framework of the gill machine. B are the fluted draft rollers which
pull the fibre thro' the fallers. C is the front roller on the frame end which
receives the straightened fibre after passing thro' the draft rollers, and C is the
corresponding roller on the end of machine. C' and C³ are support rollers for the
upper travelling band (which is rotated by friction with the lower band) and D are
weight rollers to keep the lower band always taut. Any number of the latter may
be used, according to the length of the travelling band.
The fibre as it accumulates, wraps upon the upper travelling band only, which is
preferably made of coarse flannel or other substance which will make the lap adhere
to it somewhat.
The bottom travelling band can be made of leather, but I find that good oilcloth
is preferable.
At the end of the long frame is an apparatus for folding up the "lap" in cans,
(after the endless fibrous lap has been broken by hand) so that the "laps" can be
removed elsewhere to another machine to be further dealt with. Any kind of
folding machine in use may be used for this purpose.
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 what I claim is-
-
1. In place of winding drums at the end of gill box or drawing machines, the use
of long endless aprons or bands in the manner described and set forth.
2. The use of a crease or folding machine at end of such apron, for wrapping up
the "lap" when required to be taken away.
