PROVISIONAL SPECIFICATION.
Improvements in Roller Traverse Motions of Spinning Machinery.
We GEORGE HURST of 58 Christ Church Street, Preston in the County of
Lancaster, Manager, and JOHN FENTON, of 22 Hesketh Street, Ashton on Ribble,
Overlooker, do hereby declare the nature of this invention to be as follows:-
"
ог
This invention relates to improvements in the traverse motion of spinning
"hollows" which are so soon worn in
machinery whereby the objectional "cuts
the intermediate rollers, by reason of the "changes" of direction, in which the threads
or yarns are moving taking place each time on the same part of the rollers, are
obviated, and the object of this invention is to do away with the repeated changes at
one point, and consists of an improved device whereby the number of times that the
yarns or threads move to, and fro, between the rollers, before coming to the original
starting point, can be regulated and varied as desired.
According to this our said invention we employ a bracket fixed to the end frame,
and on this bracket is a toothed wheel, driven from any convenient going part, this wheel
has a long boss on which is a pinion wheel gearing with and driving another wheel,
carried on the bracket before mentioned, on the boss of which is carried an eccentric
adjustable by means of a slot and bolt, this eccentric also carries a cranked finger to
which is attached a rod connecting the cranked finger with the transverse rod and
guide eyes," one end of the crank finger is operated by a double cam or series of
cams on the long boss of the wheel first herein mentioned.
The motion is as follows:-
Motion is imparted to the wheel first herein mentioned, from any convenient going
part, and by means of the pinion to the second wheel, eccentric, crank arm, and
traverse rod, and the to and fro motion given to the traverse rod by the cam or cams
is varied by the eccentric, as it will be seen the change of motion, if the cams are of
equal size, would take place at the same part of the intermediate rollers each time but
when our improvements are employed the "change" takes place each time at a
different part of the intermediate rollers until the wheels and eccentric have made
one revolution, and the number of "changes" for each revolution can be varied by
the adjustable eccentric and the relation of the wheels.

Improvements in Roller Traverse Motions of Spinning Machinery.
We GEORGE HURST, of 58 Christ Church Street, Preston in the County of
Lancaster Manager, and JOHN FENTON, of 22 Hesketh Street, Ashton on Ribble,
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 :-
دو
This invention relates to improvements in the traverse motion of spinning
or hollows which are so soon worn in
machinery whereby the objectional "cuts
the intermediate rollers by reason of the "changes" of direction, in which the threads
or yarns are moving taking place each time on the same part of the rollers, are
obviated, and the object of this invention is to do away with the repeated changes at
one point, and consists of an improved device whereby the number of times that the

page_text: yarns or threads move to, and fro, between the rollers, before coming to the original
starting point, can be regulated and varied as desired.
According to this our said invention we employ a bracket fixed to the end frame,
and on this bracket is a toothed wheel, driven from any convenient going part, this
wheel has a long boss on which is a pinion wheel gearing with and driving another
wheel, carried on the bracket before mentioned, on the boss of which is carried an
eccentric, adjustable by means of a slot and bolt, this eccentric also carries a cranked
finger to which is attached a rod connecting the cranked finger with the traverse rod
and "guide eyes," one end of the cranked finger is operated by a double cam or series
of cams on the long boss of the wheel first herein mentioned.
The action is as follows.
Motion is imparted to the wheel first herein mentioned, from any convenient going
part, and by means of the pinion to the second wheel, eccentric, crank arm, and
traverse rod, and the to and fro motion given to the traverse rod by the cam or cams
is varied by the eccentric, and the number of "changes" for each revolution can be
varied by the adjustable eccentric and the relation of the wheels.
Such being the nature and object of our invention, the following is a complete
description of same reference being had to the accompanying sheet of drawings in
which :-
:-
Fig. 1. is a plan view of our improved variating traverse motion.
Fig. 2. is an end elevation of same shewing the bracket by which the motion is
secured to the end frame.
Fig. 3 is a diagram illustrating the to and fro motion, and how the change of
direction of the traverse is made every time at a different part of the roller, until the
whole has been traversed.
According to this our said invention we employ a bracket 1, which is fixed to the
end of the spinning frame, and on this bracket 1 is a toothed wheel 2, driven by a
worm on the back roller shaft, or any other convenient going part; on the axis of
the wheel 2, or on a long boss of the said wheel 2 is a pinion 3 gearing with and
driving the wheel 4 carried on the bracket 1 before mentioned, and on the axis of
the wheel 4 is mounted an adjustable eccentric 5 adjusted by means of the slot 6 and
bolt 7. Pivoted on the eccentric 5 is the cranked finger or lever 8 to which is
attached the traverse rod 9 connecting the cranked finger 8 to the "guide eye." The
beak 8 of the cranked finger 8 is actuated by a cam 10 having three or other number
of throws mounted on the long boss or axis of the wheel 2.
The traverse rod 9 conveys the motion to the "guide eyes" and traverse, to which
a spiral spring is attached, thus keeping the lever 8 against the cams 10. It will
readily be seen that, although the cams 10 on the axis of the wheel 2 give a regular
motion to the cranked lever 8 and traverse rod 9, the eccentric fulcrum 5 of the
lever 8 thus gives an ever varying motion to the traverse.
The advantage of the above described traverse, over the ordinary one consists in
that it does not admit of a concentration of wear on one portion of the surface of the
rollers but ensures a regular distribution over the whole surface whereby the latter is
kept even and true so greatly adding to the utility and efficiency of the rollers
preventing the wearing hollow, and cutting of the leather covering of the inter-
mediate rollers 11 (see Fig. 3) causing them to wear quite level and true, consequently
the rollers will last a much longer time than usual, the spinning is also improved,
and a more even and better yarn or thread is produced; this is accomplished by
causing the to and fro motion to keep changing upon a different point on the inter-
mediate rollers 11 and allowing no "dwell" in one place (see Fig. 3) as shewn by the
diagram where it will be seen the motion changes its direction several times before
having finally crossed the intermediate rollers 11, and has a similar action on its
return, and each time it crosses and recrosses its various changes are made on different
points until the whole surface has been traversed, and has had an equal amount of
wear, both as regards points of change of direction, and traverse of yarn over the
surface of the rollers.

invention and in what manner the same is to be performed we declare that what
