Improvements in Slubbing, Intermediate, and Roving Frames
employed in the Preparation of Fibrous Materials for
Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows :-
:-
My invention relates to improvements in the stop motion of slubbing, inter-
mediate and roving frames employed in the preparation of fibrous materials for
spinning, and the chief object of my improvements is to automatically disengage
the lifter reversing bevel gears from the bevel pinion driving the same (and which
is fixed on the upright shaft) when the frame is stopped at full bobbins, so that
the lifting rail may be raised or lowered to the top or bottom of the lift, and
further to automatically move one of the lifter reversing bevels into gear again
when the stop motion is re-set prior to beginning a fresh set of bobbins.
I accomplish this object by attaching a lever or other appliance to the ordinary
stop motion lever which actuates the stopping and starting rod to move the driving
belt from the fast to the loose pulley. This lever is caused by the motion of the
stop motion lever when knocking off to depress one of the catches which holds the
reversing mechanism thereby allowing the reversing bevel, which is at the time in
gear with the bevel on the upright shaft, to come out of gear but by a stop on the
fever or other appliance, or by a separate stop actuated through the movement of
said lever, the rod or other part which moves the reversing bevels, is prevented
from moving sufficiently far to allow the opposite bevel to get into gear.
When the stop motion lever is re-set the lever which depressed the catch is
simultaneously removed, and the stop taken out of the path of the reversing rod,
thus allowing the ordinary weights or springs to move the said rod the full distance
to complete the change.
In certain machines when necessary or desirable I pivot an L shaped lever or
other suitable device on the frame preferably on the roller beam, so that when the
cone strap is wound back to the starting point, whilst both the reversing bevels are
out of gear and the machine stopped, a catch or projection on the cone strap fork
guide rail will move one end of this lever and cause the other end to act on and
automatically re-set the stop motion lever.

employed in the Preparation of Fibrous Materials for
Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, of Soho Iron
Works, Oldham; in the County of Lancaster, Engineer, 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:-
My invention relates to improvements in the stop motion of slubbing inter-
mediate and roving frames employed in the preparation of fibrous materials for
spinning, and the chief object of my improvements is to automatically disengage
the lifter reversing bevel gears from the bevel pinion driving the same (and which
is fixed on the upright shaft) when the frame is stopped at full bobbins, so that the
lifting rail may be raised or lowered to the top or bottom of the lift, and further
to automatically move one of the lifter reversing bevels into gear again when the
stop motion is re-set prior to beginning a fresh set of bobbins.
I accomplish this object by attaching a lever or other appliance to the ordinary
stop motion lever which actuates the stopping and starting rod to move the driving
belt from the fast to the loose pulley. This lever is caused by the motion of the
stop motion lever when knocking off to depress one of the catches which holds the
reversing mechanism thereby allowing the reversing bevel, which is at the time in
gear with the bevel on the upright shaft, to come out of gear but by a stop on the
lever or other appliance, or by a separate stop actuated through the movement of
said lever, the rod or other part which moves the reversing bevels is prevented
from moving sufficiently far to allow the opposite bevel to get into gear.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a front elevation of part of a slubbing, intermediate or roving frame
to which my improvements are applied.
Fig. 2 is an end elevation of Fig. 1 and
Figs. 3 and 4 are detail views of parts of the mechanism.
In these views, a designates the frame of the machine, bb¹ the pair of fast and
loose driving pulleys, e the stop motion rod for actuating the strap fork and
shifting the belt (not shown) from one pulley to the other, d is the ordinary stop
motion lever, which is pivoted on a stud d¹, e e are the cones, e¹ the cone strap,
e the forks and e* the cone strap fork guide rail, fis the upright shaft which drives
the jack-in-box or differential motion, the bevel pinion on the upright shaft,
ggare the lifter reversing bevel wheels, which are fixed on the sliding shaft g
aud gear alternately with the bevel f' on the upright shaft, h is the reversing rod
which is connected at one end to the sliding shaft g and at the other end by an
extension to the swivel lever i and i¹ and is moved at the required time by the
usual mechanism or by any special mechanism such as the lever and coiled
springs h' h² arranged as described in the Specification to my Patent numbered 5572
of 1895. The swivel lever i is pivoted on the stud j and is latched alternately by
the building motion catches k k'.
According to my improvements I employ a lever such as the elbow lever m
which is fulcrumed on the stud n, and has formed upon it two stops or
projections m² m². The long arm of the lever m is slotted and a stud d' on the
stop motion lever engages this slot and connects the two levers d and m together.
A weight p is connected in any well known manner by a cord pl passing round
guide pulleys på p³ on the lever d to the cone strap fork guide rail e³.

page_text: When the stop motion lever d is released at the completion of a set of bobbins,
the weight p acting on said lever causes it to move the stop motion rod c in the
direction of the arrow, Fig. 1, and so shift the driving belt from the fast pulley b
to the loose pulley b' and simultaneously the movement of the stop motion lever d
actuating the connected lever m depresses its short arm and so causes the
projection m to depress the building motion catch k and release the swivel lever i
which as already described is connected at i to the reversing rod h. The rod / is
then moved by the charged spring or the usual mechanism as the case may be in
the direction of the arrow far enough to take the lifter reversing bevel g¹ out of
gear with the bevel on the upright shaft; but is prevented from moving far
enough to gear the reversing bevel 2 with the bevel f' by the projection m² which
catches the extension on the end of the reversing rod and stops its further
movement as clearly shown in Fig. 3. Both reversing bevels g' 9' being out of
gear with the bevel the lifting gearing is thus detached from the other motions
of the machine, and the bobbin rail may be lowered or wound down by hand in
any well known manner so that the first lift of the bobbin rail is of the maximum
length. Before re-starting the frame the stop motion lever d is put back into the
position shown in Fig. in the usual way and this will simultaneously re-set the
lever m and take the projection m² out of the path of the reversing rod thus
allowing the actuating mechanism, in this case the spring h', to move the said rod
the full distance to complete the change and gear the reversing bevel g* with the
bevel f'.
In certain machines when necessary or desirable I employ an ☐ shaped lever g
(or other suitable device) pivoted on a stud q' on the frame a and one end of which
is in contact with an arm d³ of the stop motion lever d and I fix on the cone strap
fork guide rail e a bracket e which when the cone strap is wound back to the
starting point, whilst both the reversing bevel gears g¹ g² are out of gear and the
machine stopped, will come in contact with and move one arm of the lever q and
cause the other arm to act on and automatically re-set the stop motion lever d and
the lever m connected thereto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with the stop motion lever d or its equivalent, of means,
such as the lever m furnished with projections m¹ m², for actuating one of the
building motion catches and releasing the reversing rod and interrupting the
movement of said rod when released so as to disengage the lifting gearing and
enable the bobbin rail to be wound or moved by hand into its initial position.
2. The combination with the stop motion lever d and the connected lever m, of
the lever and bracket for automatically re-setting the stop motion lever when
the cone strap is wound back to the starting point.
3. The construction, combination and general arrangement of parts embodying
my improvements in slubbing, intermediate and roving frames substantially as and
for the purposes herein described and as illustrated by the accompanying
drawings.
