PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Imparting a Varying Movement to
the Roller Traverse in Preparing and Spinning Machines.
I, JAMES EDGE, of Gorton, in the County of Lancaster, Mill Manager, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the traverse or traverse motion connected with the
guide eyes whereby the sliver or thread of cotton-or other fibre-is guided or
delivered to the drawing rollers at different points along the surface of the roller
and is designed to give a variable traverse which while the length of the traverse
remains practically constant the limits of the traverse or points at which it changes
its direction of motion will be constantly varying.
In carrying out the invention I convey the motion to the traverse bar in the
usual way from one of the rollers or other convenient part of the machine by a
wheel gearing with a worm thereon.
The worm wheel 1 mount upon a stud carried by a sliding bracket which slides
to and fro on the roller beam or upon a plate or bracket affixed thereto. As the
bracket moves to and fro the worm wheel is moved backwards and forwards below
the worm with which it gears but not to such an extent as to allow the wheel to
come out of gear with the worm.
In connection with the worm wheel either on the same spindle or driven by it I
place a second worm preferably on the same spindle and of suitable diameter which
turns slowly and gears with a second worm wheel by which the sliding bracket is
moved to and fro.
On the face of the second worm or connected with it is an eccentric or crank
pin preferably the former which engages with the end of the traverse rod or a
bracket attached thereto by which as the wheel is rotated the traverse rod is moved
to and fro.
On the face of the second worm wheel or connected with it is a crank pin or
eccentric preferably the former connected to a connecting rod or bracket fixed to a
stationary stud or bracket the roller beam or on any other suitable or convenient
part of the machine which as this second worm wheel is mounted upon the sliding
bracket causes the bracket to move to and fro as the wheel rotates.
The position of the wheels and worm may be adjusted on the sliding bracket and
the eccentrics or crank pins may also be movable so that the throw may be altered
as may be required.
The sliding bracket may be secured by a couple of stud bolts or the end of the
stud which carries the second worm wheel may pass down through a slot in it into
the beam a sleeve being fitted into the hole in the beam to provide a steadying or
bearing surface.
By this arrangement of parts the eccentric of the second worm moves the traverse
rod an equal distance at each revolution and the eccentric or crank on the second
worm wheel slowly moves the bracket carrying the first eccentric to and fro which
causes the traverse to be gradually varying within certain limits.

Improvements in Apparatus for Imparting a Varying Movement to
the Roller Traverse in Preparing and Spinning Machines.
I, JAMES EDGE, of Gorton, in the County of Lancaster, Mill Manager, 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 the traverse or traverse motion connected with the
guide eyes, whereby the sliver or thread of cotton or other fibre-is guided or
delivered to the drawing rollers at different points along the surface of the roller,
and is designed to give a variable traverse which, while the length of the traverse
remains practically constant, the limits of the traverse or points at which it changes
its direction of motion will be constantly varying.
It consists essentially in constructing the apparatus with the eccentric or other
device which moves the traverse rod mounted upon a bracket or carriage moved
with a sliding or reciprocating movement to and fro by an additional eccentric or
crank device so that the axis of the first eccentric receives a slow reciprocating
movement and is constantly altering its position.
The invention will be fully described with reference to the annexed drawings in
which as an example the apparatus is shown as applied to a roving frame.

Fig. 6. End elevation of same.
Movement is conveyed to the traverse motion in the usual way from one of the
rollers, or other convenient part of the machine; by means of a worm gearing into a
worm wheel.
The worm wheel A which gears with the worm a upon the roller (see Figs. 1
to 6) rotates upon a stud or pin B. Connected to or driven by the worm wheel A,
is an eccentric C, by which the traverse rod is moved to and fro as it revolves,
preferably attached to and rotating on the same stud B as the worm wheel A. The
stud upon which the eccentric C rotates is carried by a sliding bracket D,
which is moved to and fro upon the bracket or plate E affixed to the roller beam.
A second worm F, either connected to or driven by the worm wheel A, preferably
connected to it, and rotating on the same spindle, imparts motion to the sliding
bracket D, through a worm wheel G, with which it is geared. The worm wheel G
is mounted on a spindle H, connected to which is a second eccentric I. This
eccentric I, as the wheel G revolves, is rotated between the fixed lugs or projections e
of the fixed bracket E, thereby causing the sliding bracket D to move to and fro
as the wheel rotates.
As the sliding bracket D moves to and fro, the position of the eccentric C
which engages with the bracket H¹ of the traverse rod, is gradually altered
backwards and forwards, and the worm wheel A is moved backwards and forwards
below the worm with which it gears.
In Figs. 1 and 2, the bracket H¹ depends from the traverse rod h, the traverse
rod being secured or bolted thereto.
In the modification shown in Figs. 4-5-6, the foregoing description will
fully apply, like parts being marked with the same reference letters, but their
position is differently arranged, in addition to which the traverse bracket His pivoted
to the bracket E, at e'. It will however be obvious, that if the bracket D be
provided with a foot, and be fixed thereby to the roller beam, and the bracket E
be made to slide to and fro beneath it, the same results will be obtained, as the

page_text: pivot e will be moved to and fro, and the relative position of the traverse rod h be
thereby altered.
It will be evident, that instead of a fixed bracket upon which the sliding bracket
moves, the sliding bracket may move to and fro on the roller beam, and the second
eccentric or crank may be connected by a connecting rod or arm to a stud or other
fixture fastened to the beam.
The position of the wheels and worm may be adjusted on the sliding bracket, and
the eccentrics or crank pins may also be movable, so that the throw may be altered
as may be required.
By this arrangement of parts, the eccentric C moves the traverse rod an equal
distance at each revolution, and the eccentric or crank I, of the second worm wheel,
slowly moves the sliding bracket D, carrying the first eccentric C to and fro, which
causes the traverse to be gradually varying within certain limits.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for imparting movement to the traverse rod, having the eccentric,
which moves the traverse rod to and fro, mounted upon and carried by a reciprocating
sliding bracket or carriage, substantially as described.
2. An apparatus for imparting motion to the traverse rod, having a single
worm wheel, which is driven from the rollers; an eccentric, which moves the
traverse rod to and fro; a reciprocating sliding bracket, which carries the eccentric,
and a second worm and worm wheel with a second eccentric, which transfer motion
to the sliding bracket, with or without a pivoted connecting bracket between the
eccentric and the traverse rod, substantially as described.
3. An apparatus for imparting a varying reciprocating motion to the traverse,
with the several parts constructed and arranged substantially as and for the purpose,
described.
