I, PETER O'HARA, of 25 Argyle Street, Keighley, in the County of York, Over-
looker, do hereby declare the nature of said invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING WOOL AND OTHER FIBROUS SUBSTANCES
TO BE COMBED," to be as follows:-
My invention relates to what are known as preparing or drawing machines,
(also technically called gill-boxes,) in which wool or other fibrous substances are
prepared for being combed.
In such machines the material having been fed by being spread on a continuously
moving endless band or sheet is carried between what are called back rollers, then
through or between another pair of rollers provided with card teeth, after which it
is caused to pass by means of a system of fallors provided with pins and actuated
by screws, to another pair of rollers whereby it is drawn and delivered in the form
of a "ribbon or lap."
Several such preparing machines are usually required to complete the prepara-
tion of the material ready for the combing operation.
According to my invention, that part of the machine or gill box which carries
the above mentioned endless band or sheet whereon the material is fed, is together
with the back rollers and those rollers having the card teeth, made separate from
the remainder of the machine and capable of having imparted thereto by suitable
mechanism, a reciprocating movement to and from the fallers, such movement being
so timed that immediately when a faller has been raised from the lower screws of
the gill-box to the upper ones, pierced the material, and commenced its movement
towards the front rollers of the machine, thereupon the said separate part of the
gill-box shall first follow such faller, and then whilst the succeeding faller is being
raised or just before it is raised, the said separate part of the gill-box shall recede
from the system of fallers and thus partially draw and open the material at that
part between the back rollers and the fallers, these to and fro movements being
repeated for every faller raised.
With this arrangement the preparation of the material under treatment may be
completed in less time and consequently at less cost than by the means heretofore
usually employed and without having to pass it through the same number of
machines as heretofore has been customary.

I, PETER O'HARA, late of 25 Argyle Street, now of 83 Hanover Street, Keighley,
in the County of York, Overlooker, 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 relates to what are known as preparing or drawing machines
(technically called gill boxes) in which wool or other fibrous substances are
prepared for being combed.
Usually the material to be prepared is supplied to the machine as follows:-It
is spread upon a continuously moving endless band or sheet, which carries it up
to, and so that it passes between what are known as back rollers, thence it proceeds 1
in some cases between another pair of rollers which may either be provided with
card teeth or may be what are known as porcupines, but in some cases the last
mentioned pair of rollers or porcupines may be dispensed with. From the back
rollers or from the secondly mentioned rollers or porcupines as the case may be.
the material under treatment is conveyed by a system of fallers provided with
pins and actuated in a usual manner, to another pair of rollers whereby it is drawn
and delivered in the form of "ribbon" or "lap.”
Several proparing machines such as above referred to, are usually required
to complete the preparation of the material and make it ready for the combing
operation.
Now the object of my invention is to reduce the number of machines through
which the material has to be passed, thereby reducing the number of operations
upon the material and consequently effecting its preparation at less cost than
heretofore has been usual. To this end according to my invention I construct or
provide that part of the machine or gill box which carries the before mentioned
endless feeding band or sheet and the back rollers and the rollers with card teeth
or porcupines (when the latter are used) in suchwise that the said part of the
machine is capable of having imparted to it by suitable mechanism, reciprocating
movement towards and from the said fallers, such movement being so timed as to
follow the movement of the fallers on one being raised from the lower screws to
the upper ones, and previous to another faller being raised the said reciprocating
part of the machine retires to its backward position, thus drawing that portion of
the material under treatment which for the time is between the fallers and the said
movable part of the machine.
These reciprocating movements being repeated for every faller raised.
In order that the feeding of the material may be regular I make the worm or
screw that drives the tangent wheel on the axis of one of the back rollers able to
slide to and fro upon its axis (along with the movable part of the machine) so that
it has both a rotary and an endwise motion and imparts continuous and regular
rotary motion to the back rollers. Or if other driving gear for the back rollers be
employed I arrange it to travel to and fro with the said movable part of the
machine

page_text: The accompanying drawing represents in outline a preparing or drawing
machine. a, is the framework, b, is the endless band or sheet upon which the
material under treatment is spread and carried by the action of the bottom back
roller c, in the direction of the arrow c', towards and between it and the upper back
roller c, thence to the rollers with card teeth or the porcupines d, d, when such
are used as previously referred to, thence to the fallers e, and the front or drawing
rollers ff, and between delivery rollers g, g', and h, h¹, in the form of "ribbon
or "lap" at . The movable part a', of the machine, and to which my invention
particularly relates, carries the said endless band or sheet b, the back rollers c,
and c, and the rollers with card teeth or the porcupines, is comprised within the
dotted lines 1. 2, and is shewn to slide upon the framework at a³, but if preferred
may be so mounted as to oscillate or rock upon centres or gudgeons placed at the
lower or other convenient part of the framework, it is actuated towards and from
the fallers by one or more eccentrics and links such as 1, 2, or their equivalents;
is a rotating shaft, carrying the worm or screw k, for imparting motion to the
tangent wheel 1, on the axis of the bottom back roller c; the worm k, is caused to
slide endwise on the shaft j, by the carriage m, which is either in one piece with or
attached to the reciprocating part a As the reciprocating part a', makes its
backward movement in the direction of the arrow n, it draws that portion of the
material under treatment, which for the time is between the fallers and the said
movable part, and this drawing occurs for each faller raised from the lower series
to the upper as previously mentioned, repeated drafts of the material takes place
as desired and thus dispenses with the necessity of being drawn by passing it
through the same number of machines as heretofore usual.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is
In machinery or apparatus for preparing wool and other fibrous substances to be
combed.
1. Imparting a reciprocating motion to that part of a drawing or preparing
machine known as a "gill box," comprising the feeding portion, the back rollers
and porcupines or their equivalent (in cases where the latter are used) so that such
reciprocating parts may approach and recede from the system of fallers sub-
stantially as and for the purpose hereinabove described and shewn in tho
drawing.
2. Apparatus comprising a reciprocating portion of a gill box, constructed,
arranged and operating as described and illustrated in the annexed drawing for the
purpose set forth.
