PROVISIONAL SPECIFICATION,
An Improvement applicable to Drawing Frames and Combing
Machines.
We, JOHN CATTERALL, Mill Manager, WILLIAM CREECHI, Fitter, and MATTHEW
CONLAN, Carding Manager, all of Messrs. McConnell & Co., Limited, of Henry
Street, Ancoats, Manchester, in the County of Lancaster, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to prevent the flat sliver of cotton, (or other
fibrous substance) as it is being drawn through the drawing rollers in such
machines, to the sliver cans, from becoming fluffy and broken at the edges, which
is a great source of waste and also imperfect yarn in the course of spinning in the
after processes, and our invention is designed to remedy this defect by causing the
fibres to be confined and consolidated at the selvages by passing the flat sliver
through a suitable guide plate on the machine.
For this purpose we provide a flat piece of metal (or other suitable material)
which is somewhat in the form of a bridge, which we place between the front and
second of each set of drawing rollers, the lower edges of such guide piece or
bridge may be supported by and rests or bears upon the "under clearer."
By this means the sliver previously to being delivered from the drawing rollers,
is caused to pass through this guide plate or bridge piece aforesaid which has
the effect of keeping the fibres more confined at the edges and thus consolidating
the selvages and preventing waste of fibre and hence producing a better yarn in
the subsequent treatment of the material.

An Improvement applicable to Drawing Frames and Combing
Machines.
We, JOHN CATTERALL, Mill Manager, WILLIAM CREECHI, Fitter, and MATTHEW
CONLAN, Carding Manager, all of Messrs. McConnell & Co., Limited, of Henry
Street, Ancoats, Manchester, in the County of Lancaster, 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 main object of this invention is to prevent the flat sliver of cotton or other
fibrous material, as it is being drawn through the drawing rollers of such

page_text: machines, on its way to the sliver cans, from becoming fluffy and broken at the
edges, which is a great source of waste and also of imperfect yarn, in the course
of spinning in the after processes.
Our invention is intended to remedy this defect by causing the fibres to be con-
fined and consolidated at the selvages by passing the flat sliver through a suit-
able guide plate or bridge piece which is placed between the draw rollers on the
machine.
In order that our invention may be clearly understood we have hereunto annexed
a sheet of drawings (showing the invention applied to a drawing frame) which
are marked with figures and letters of reference corresponding with those in the
following explanation thereof.
Fig. 1 on the annexed drawing is a front view of so much of a drawing frame
as is necessary to show the application of the invention thereto. Fig. 2 being a
transverse section of the same. Fig. 3 is a front view of one form of bridge
piece drawn about full size, and Fig. 4 an end view of the same.
For the purpose of our invention we provide a flat plate a or piece of metal,
vulcanite or other suitable material, which is made somewhat in the form of a
bridge, as shown at Fig. 3, which we place between the first and second of each
set of drawing rollers be, the lower edge or limbs al of such guide or bridge piece
may be supported by and rest or bear upon the under clearer d, which latter we
prefer to make of the form shown in Fig. 5. The top part d' or surface of such
clearer on which the bridge piece rests is preferably left smooth and free from the
felt covering so that there is less friction to overcome during the traverse thereof.
By this means as the sliver, previously to being delivered from the drawing
rollers to the sliver cans, is caused to pass through this guide plate or bridge
piece, it has the effect of keeping the fibres more confined at the edges, thus con-
solidating the selvages and preventing roller laps and waste of fibre, and hence
producing a better and superior yarn in the subsequent treatment of the material,
besides which the front rollers can be run quicker and thereby greatly increase
the output.
In applying the invention to combing machines, the bridge piece is placed
between the calendering rollers and drawing rollers at the delivery end of such
machines.
We would remark that although the invention is intended mainly for protecting
the slivers in drawing frames and combing machines, yet it will be evident that a
somewhat similar arrangement of guide plates or bridge pieces may be applied to
slubbing and roving frames, as shown at Fig. 6, the guides in these latter cases
being made with one, two or more bridges as shown at Figs. 7 and 8.
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:-
1. The improvement applicable to drawing frames and combing machines, con-
sisting in the use or employment of a guide or bridge piece for the purpose of
keeping the selvages of the sliver consolidated substantially as and for the pur-
pose hereinbefore described, and illustrated on the drawings annexed.
2. A guide plate or bridge piece to be applied to drawing frames and combing
machines as and for the purpose herein before described and shown on the drawings.
