Improvements in Traverse Mechanism for Preventing the Grooving
of the Rollers used in Machines for Preparing and Spinning
Fibrous Materials.
We, WILLIAM HALL COOK of 96 Stanley Grove Longsight in the County
of Lancashire Assistant Manager and JAMES HARRISON of 82 Stanley Grove
Longsight in the County of Lancashire Assistant Manager. We do hereby declare
the nature of this invention to be as follows :--
Our invention is designed for the purpose of producing
a reciprocal motion
but varying in distance travelled and between varying points of change its object
being to prevent the wearing of grooves in or the cutting of rollers used in
machinery for preparing or spinning fibrous materials. Mounted upon a stud
fixed to any convenient part of the machine are two wheels varying in their
number of teeth by one or any other desirable number, to each of these wheels
is fixed an eccentric. and on each of these eccentries works a link or rod, these
two rods being connected to a common bracket one rod being connected to the
bracket at one of its ends, the other rod at any convenient distance from the
bottom of the bracket to the end of the bracket opposite to where the rod is
connected, is attached a stud moveable up and down in a slot cast in the bracket,
this stud works in a hole drilled in the traverse rod or any suitable fixing attached
thereto, the stud is moved up or down in the slot of the bracket so as to give
a longer or shorter extreme traverse, the wheels are driven by a worn cut in the
roller, or placed on any convenient part of the machine, and as this worm drives
the wheels one of the eccentrics is constantly varying its position in relation to the
other so that at one time the eccentrics will be both moving the connecting rods
and with them the bracket in the same direction and at another time one eccentric
will be throwing its rod in one direction and the other eccentric will be throwing
its rod in the other thus communicating a varying motion to the end of the bracket
fixed or connected to the traverse rod.

Improvements in Traverse Mechanism for Preventing the Grooving
of the Rollers used in Machines for Preparing and Spinning
Fibrous Materials.
We, WILLIAM HALL COOK, of 96, Stanley Grove, Longsight, in the County
of Lancaster, Assistant Manager, and JAMES HARRISON, of 82, Stanley Grove,
Longsight, in the County of Lancaster, Assistant 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:-
or
This invention is designed to produce a reciprocating motion varying in the
distance travelled at each stroke or varying the point upon which the direction of
movement changes at the end of each stroke, to be applied to the "traverse
traverse rod of spinning or other similar frames, with the object of preventing
the wearing of grooves in, or the cutting of the leather covered rollers between
which the rove or liver of material passes.
It consists essentially in constructing the apparatus with two indeperlent

On a fixed bracket A placed on the roller beam or other convenient position in
the machine, we mount two separate eccentrics B B working independently of
each other, and each fitted with a connecting rod or link C C by which the motion
of the two eccentrics is conveyed to a common bracket D, pivoted to the traverse
rod E. Each of the eccentrics we prefer to form on the side of a toothed wheel
which receives motion from a worm or other gear, and by which they are rotated.
Referring more particularly to Figs. 1 to 5, the two eccentrics B B are each
formed on the face of a worm wheel FF and are mounted side by side on a stud
carried by the fixed bracket A. The two worm wheels vary in size by one or
more teeth so that their relative position and that of the eccentrics is constantly
varying. On the traverse rod E, is pivoted the bracket D, to which both
eccentrics are connected by the rods or links CC. The bracket is pivoted at one
end to the traverse rod, and at its other end is pivoted the connecting rod C, the
connecting rod C being pivoted to it by a separate pivot at a convenient distance
from the bottom of the bracket. The bracket D is provided with a longitudinal
slot at its upper end, and is connected to the traverse rod E by a stud d, the
position of which is adjustable in the slot. The stud d is fast to the bracket D,
and pivoted or free to rotate in the bracket e fitted to the traverse rod E. The
ends of the connecting rods are each pivoted on studs e e¹ made fast in transverse
slots. The throw or length of traverse of the rod E can be regulated or adjusted
as required by altering the position of the studs d, e, or e' in their respective slots,
so as to give a longer or shorter extreme traverse. The wheels Fare driven
by the worm G cut in or fixed upon the back roller, or by any other suitable
arrangement.
Referring more particularly to Figs. 6 to 10, the same description will in
most part apply to the modified form of the apparatus, but instead of both
eccentrics BB and their respective wheels F F being mounted on the same stud
or centre, they are mounted upon separate studs, and the wheel F1 driven from a
wheel F connected to the worn wheel F, as by this means greater variation or
difference in the speed of the two eccentrics B can be obtained. In the
drawings a star or stud wheel is shown at F connected to the eccentric B, which
is actuated by a stud or projection" on the wheel F" by which the wheel F, and
eccentric B are moved forward one tooth at each revolution of the eccentric B
and wheel F. It is evident however that the two eccentrics may be geared
together by pinions if desired. The wheel F is driven by the worm G on the back
roller.
In operation, motion is conveyed from the worm G on the roller shaft to the
eccentric BB' through the wheel, FF, and in the first example, as one
eccentric is driven faster than the other and their relative positions gradually and
constantly changing, the eccentrics will at one time be both moving the connecting
rods or links CC, and with them the bracket D in the same direction, and at
another time one eccentric will be throwing its connecting rod in one direction, and
the other eccentric its connecting rod in the opposite direction, thus communicating

a constantly varying traverse to the end of the bracket D and traverse rod E.
the second example, the constant movement to the traverse rod is effected by the
eccentric B and connecting rol C, while the end of the connecting rod ("acts as
a fulcrum, the position of which is altered at each revolution of the eccentric B by
the movement given to the eccentric B thus communicating a varying motion to
the end of the bracket D fixed or connected to the traverse rod E.
Having now particularly described and ascertained the nature of the said inven-
tion, we wish it to be understood that we are well aware that two eccentries have
been used to vary the traverse where one eccentric has been placed inside the other
or to act directly upon the other, and that such have been actuated by two worin
wheels of different diameter gearing together into a single worm, and we do not
make any claim therefor, but we declare that what we claim is:-
1. An apparatus for imparting a variable motion to the traverse rod in preparing
and spinning machines having two independent eccentrics working separately, and
connected by separate connecting rods or links to a common bracket pivoted to the
traverse rod substantially as described.
2. An apparatus for imparting a variable motion to the traverse rod in preparing
or spinning frames having the several parts constructed and arranged substantially
as described and shown either with reference to Sheet 1 of the drawings Figs. 1
to 5, or with reference to Sheet 2 of the drawings Fig. 6 to 10.
