An Improved Traverse Motion for Preparing Spinning and other
Machinery.
We, BENJAMIN ORMEROD, Mill Manager, GEORGE HAWORTH Carder, and
JOHN FROST DAVIES, Foreman Engineer, all in the employment of Messieurs
John Dugdale and Sons, of Blackburn, in the County of Lancaster, do hereby
declare the nature of this invention to be as follows:-
Our invention is particularly applicable to the machinery used in preparing
and spinning cotton and other fibre and the object of the invention is to over-
come the wear on the rollers through which the cotton or other fibre passes,
caused by the constant reversal, at the same position, of the traverse guides
when driven in the usual manner. The effect of the usual traverse is to wear
the rollers in the two positions where the change of motion takes place and
thereby cause bad yarn and unnecessary wear on the rollers, whether leather or
metal covered.
In carrying out our invention we employ in one arrangement a train of
differential gearing, motion being given by worm or equivalent to the usual
worm wheel and eccentric; on this eccentric is mounted loosely a pinion which
is geared into an internal wheel fixed upon the stud that carries the worm wheel
with its eccentric and the pinion; the boss of the pinion is eccentric upon which
is fitted an eccentric strap the rod of which is pivoted to the usual rocking
lever or equivalent part connected to the traverse motion rod that carries the
thread or other guides. The worm wheel, pinion or spur wheel and internal
wheel have different numbers of teeth and this combined with the eccentrics
imparts a differential movement to the eccentric strap and traverse motion rod
whereby the change of traverse of the guides takes place at a different point
every stroke until the cycle having been completed the wheels regain their
initial positions and a similar round of varying movements is repeated.
As an alternative for the outer eccentric and eccentric strap we may secure
upon the boss of the pinion, a cam or equivalent means either alone or in
combination with weights or springs to impart to the rocking lever and the
traverse guide rod a variable reciprocating movement.
In order to give an additional and continuous movement to the traverse guide
rod we fit on a sliding key in the back roller shaft a boss which carries a sleeve
with an eccentric groove round its periphery; the boss is provided with a shank
or stem which is secured to any reciprocating part of the improved traverse
motion above described or it may be to any other traverse motion in such manner
that the boss slides to and fro on the back roller shaft to the full extent of the
traverse motion and traverses the guide rod. A finger or other projection on the
traverse guide rod lies in the eccentric groove whereby the rotating motion of
the roller shaft is imparted by the eccentric to the traversing guide rod and thus
gives to the latter a short but quick to and fro movement in addition to its ordinary
traverse motion.
As an alternative we fit upon a feather key in the back roller shaft a worm
carried in a bracket which also carries a stud on which is fitted a pinion in gear
with the worm; on the stud is also a small eccentric which is fitted in a strap to
which the end of the traverse guide rod is secured; the end of the stud is secured

page_text: to any portion of the improved or ordinary traverse motion and by this means also
we obtain a compound movement of the traverse guide rod.

An Improved Traverse Motion for Preparing Spinning and other
Machinery.
We, BENJAMIN ORMEROD, Mill Manager, GEORGE HAWORTH Carder,_and
JOHN FROST DAVIES, Foreman Engineer, all in the employment of Messrs. Johu
Dugdale and Sons, of Blackburn, 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 :-
Our invention is particularly applicable to the machinery used in preparing and
spinning cotton and other fibre, and the object of the invention is to overcome the
wear on the rollers through which the cotton or other fibre passes, caused by the
constant reversal, at the same position, of the traverse guides when driven in
the usual manner. The effect of the usual traverse is to wear the rollers in the two
positions where the change of motion takes place and thereby cause bad yarn and
unnecessary wear on the rollers whether leather or metal covered.
In carrying out our invention we employ in one arrangement a train of
differential gearing, motion being given by worm or equivalent to the usual worm
wheel and eccentric; on this eccentric is mounted loosely a pinion which is geared
into an internal wheel fixed upon the stud that carries the worm wheel with its
eccentric and the pinion; the boss of the pinion is eccentric upon which is fitted an
eccentric strap the rod of which is pivoted to the usual rocking lever or equivalent
part connected to the traverse motion rod that carries the thread or other guides.
The worm wheel, pinion or spur wheel and internal wheel have different numbers of
teeth and this combined with the eccentric imparts a differential movement to the
eccentric strap and traverse motion rod whereby the change of traverse of the
guides takes place at a different point every stroke until the cycle having been
completed the wheels regain their initial positions and a similar round of varying
movements is repeated.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying two sheets of drawings reference being
had to the figures and letters marked thereon.
Fig. 1 is a front view, Fig. 2 an end view and Fig. 3 a plan of our improve.
traverse motion as applied to a preparing or spinning frame and Fig. 4 a sectional
plan view, on an enlarged scale, of the eccentrics and gearing for effecting the
traverse of the rod which carries the thread guides.
Figs. 5, 6, 7 and 8 are views of four alternative arrangements of our improved
traverse motion.
Similar letters refer to similar parts throughout the several views.
Referring first to the arrangement illustrated by Figs. 1 to 4,-a is a portion of the
end of the frame, the roller stand carrying three pairs of drawing rollers c, c¹, c',
and d is a worm secured as usual to the lower back roller for actuating
mechanism to traverse the thread guide bar or rod e. Our improved traverse motion
is mounted upon a bracket f carrying a stud g to which is fastened an internal spur
wheel h into which gears a pinion i mounted loosely and eccentrically upon an
eccentric which is fitted loosely upon the stud 9 and has formed with or secured
to it a spur wheel j¹ which is driven by the worm d on the back roller shaft c². The
eccentric boss of the pinion i is surrounded by a strap k the arm of which is pivoted

page_text: at to a bar fulcrumed at l¹ to the bracket f, and the upper end of the bar / is.
connected by a rod m to the traverse rod e which is provided with thread guides or
drilled to receive and guide the rovings or threads into the nip of the back pair of
drawing rollers c². From the drawing rollers the rovings or threads pass to the
winding on bobbins shown in Fig. 2.
The operation of the traverse motion is very simple, the rotating motion
imparted to the wheel j by the worm d is conveyed by the eccentricity of the boss j
to the eccentric i and the eccentric strap which is caused to oscillate, the
oscillation however of the strap k is continually varied by the teeth in the pinion i
gearing into the teeth of the internal wheel h; whatever movement is given to the
strap is converted into a peculiar varying traverse motion on the traverse rod e
through the bar and connecting rod m.
Fig. 5 is a front view partly in section of an alternative arrangement in which
the eccentric strap k is dispensed with, the eccentric boss of the pinion i projects in
front of the eccentric ; and rests between surfaces o¹, on an arm o pivoted to the
bracket fat o; this arm is slotted at o³ and is connected to the traverse rod e by a
bolt p.
The operation of this arrangement is similar to that already described; the-
eccentric is caused to rotate by the worm d and wheel j¹, not shown, and the
motion is communicated to the pinion i whose teeth gear into the teeth of
the internal wheel so that the oscillating movement given by the eccentric ; is
constantly varied by the gearing of the toothed wheels and thus the traverse rod e
receives a varying vibratory motion.
Fig. 6 is a plan view of another alternative traverse motion in which the
eccentric strap k or other reciprocating part is pivoted at k¹ to a rod m the other
end of which is connected to a strap n on a boss q fitted and free to slide upon a
feather key in the back roller shaft c; in an eccentric groove q' in the boss q is a
stud e fitted on the end of the traverse guide rod e.
In this arrangement the rotating motion of the roller shaft is imparted by the
worm d and wheel j¹ to an eccentric or eccentrics and by them to the traverse rod e
through the boss q and an additional independent movement is given to it by the
eccentric groove y'.
Fig. 8 is a plan view of another alternative arrangement in which the worm d is
employed to give rotary motion by the worm wheel j¹ to the eccentrics j and i and
eccentric strap k which by a rod m conveys the reciprocating movement to a stud s
carried in a sliding bracket q fitted on the back roller shaft c² and this bracket ፃ
encloses a worm fitted upon a feather key fixed in the shaft c²; upon the stud sis
mounted loosely a worm wheel s¹ which is made with or has secured to it an
eccentric s fitted in a hole in a pivoted plate t to which is bolted the traverse
guide bar e.
By means of the traverse motion given to the sliding bracket combined with
the motion obtained from the worm and worm wheel and eccentric s² the traverse
guide rod receives a compound varying movement.
Fig. 8 represents an arrangement with a pair of traverse guide rods or bars and
in this case the eccentric strap k is connected at k¹ to a lever / pivoted at /
to the bracketf; the upper part of the lever / is connected by a rod m to the front
traverse bar e, while the lower end of the lever is connected by a rod m² (shown
by a dotted line) to a second traverse bar e³, which has the same number of thread
guides as the bar e, the guides or guide holes being placed alternately on
the two bars e and e2 and as the bars are constantly moving in opposite directions.
the weights act more efficiently on the top rollers.
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 combination with differential gearing, of an arrangement of eccentrics
and suitable connections for imparting a compound varying traverse motion to the
