Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames.
I, WILLIAM TATHAM, of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said invention, to be as
follows:-
In the frames to which my invention applies in which the twisted sliver is wound
on spools or bobbins made to taper at each end, the traverse of the bobbin rail has
to shorten at each layer of twisted sliver wound upon the spool, and in some cases
the mechanism for changing the direction of the traverse at each extreme fails to
act properly, and the twisted sliver then carried-beyond the proper point on. the
bobbin or spool and this causes great trouble and loss of time as the slivers in such
case all break, and in some cases breakage of the mechanism also takes place.
My invention relates to automatic arrangements for stopping the frame when in
any case the bobbin rail traverses beyond the point required by the proper taper of
the ends of the bobbins. There are in existing frames arrangements actuated by a
weight or spring which will move the stop rod and traverse the driving belt from
the fast to the loose pulley when the bobbins are full by releasing a catch and
allowing the spring or weight to act, and I connect my automatic stopping arrange-
ments with such mechanism, by jointing the upper end of a vertical rod to the said
catch, the lower end of which rod slides in a suitable bracket adjustable on the
framing.
On this vertical rod there are two fingers adjustable thereon and secured by set
screws one at the upper and the other at the lower part of the said vertical rod.
When a part which oscillates to and fro (hereinafter mentioned) comes at one
extreme of its oscillation against the upper finger on the vertical rod, the said
catch is lifted and this stops the frame, and when the oscillating part comes at its
other extreme against a two armed lever at the lower part of the vertical rod,
having its fulcrum on the said adjustable bracket then one arm of this two armed
lever acts upon the adjustable finger on the lower part of the vertical rod and lifts
it, and thus causes the said catch to be lifted and the stop rod to be released.
The oscillating part in the end of a rod and the axis of oscillation of this rod
one end of which is
coincides with that of the part known as the "tapering bar"
moved up and down by connection with a slot in a bracket secured to, and moving
up and down with the bobbin rail.
The said oscillating part or rod passes through a hole in a stud projecting from
the end of the said "tapering bar" consequently the end of the oscillating rod is
moved by the end of the "tapering bar "within the slot, but as the latter acts upon
the oscillating part or rod, nearer to its axis of oscillation as the traverse shortens,
it gives to the end of the oscillating rod the same uniform length of oscillation
whether the traverse is long or short, and if a traverse is given by failure of the
changing mechanism to act, greater than that due to the then position of the
"tapering bar" this excess of traverse causes the end of the oscillating rod to stop
the machine by releasing the said catch as above explained. By another arrange-
ment of mechanism, there is a rod arranged to slide vertically in suitable brackets
from the framing this rod has two adjustable inclined bars or edges secured to it so
arranged that when the bobbin rail begins its traverse, when the bobbin is empty,
a projection from the "tapering bar" where it enters the hereinbefore mentioned
slot in the bracket attached to the bobbin rail, will just touch or nearly so, the
edges of the said inclined bars at each extreme, this said projection from the
-

page_text: tapering bar" also touches in like manner the said inclined bars or edges when
the tapering bar is in the position when the bobbins are full and consequently this
said projection from the tapering bar-will touch or nearly touch the said inclined bars
or edges at both extremes of traverse during the entire course of filling the bobbins.
Should the traverse at any time exceed that due to the then position of the
tapering bar" the vertical rod to which the incline bars or edges are secured, is
moved either up or down as the case may be, and this movement operates to release
the before mentioned catch.
66
The vertical bar has or may have-a V bracket attached to it adjustably, and into
this Va bowl enters, which is on a stud in the vertical arm of a bell crank lever
having its fulcrum on a suitable bracket, the horizontal long arm of which is
weighted to press the bowl in the V; therefore, if the vertical rod moves either up
or down, the V will cause the long arm of the bell crank lever to lift and this
releases the said catch. There may be a weight, weight lever or spring, to counter-
balance the weight of the vertical rod and inclined bars and parts attached
thereto.
The arrangement of the mechanism may be varied without departing from its
principle of action which is to release the stopping mechanism whenever the bobbin
rail traverses to a greater extent than that due to the required taper to which the
ends of the spools are to be formed.
The improvements above described or a modification thereof are also applicable
to frames where the bobbins have heads, and the traverse of the bobbin rail is
uniform.

Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames.
I, WILLIAM TATHAM of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, 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 :-
In the frame to which my invention applies in which the twisted sliver is wound
on spools or bobbins made to taper at each end, the traverse of the bobbin rail has
to shorten at each layer of twisted sliver wound upon the spool, and in some cases
the mechanism for changing the direction of the traverse at each extreme fails to
act properly, and the twisted sliver is then carried beyond the proper point on the
bobbin or spool and this causes great trouble and loss of time as the slivers in such
case all break, and in some cases breakage of the mechanism also takes place..
My invention relates to automatic arrangements for stopping the frame when in
any case the bobbin rail traverses beyond the point required by the proper taper
of the ends of the bobbins. There are in existing frames, arrangements actuated
by a weight or spring which will move the stop rod and traverse the driving belt
from the fast to the foose pulley when the bobbins are full by releasing a catch and
allowing the spring or weight to act, and 1 connect my automatic stopping arrange-
ments with such mechanism, by jointing or otherwise connecting, the upper end of a
vertical rod to the said catch, the lower end of which rod slides in a suitable bracket
adjustable on the framing.
On this vertical rod there are two fingers adjustable thereon and secured by set
screws, one at the upper and the other at the lower part of the said vertical rod.
When a part which oscillates to and fro (hereinafter mentioned) comes at
one extreme of its oscillation against the upper finger on the vertical rod, the
said catch is lifted and this stops the frame, and when the oscillating part comes
.

page_text: at its other extreme against a two armed lever at the lower part of the vertical
rod, having its fulcrum on the said adjustable bracket then one arm of this two
armed lever acts upon the adjustable finger on the lower part of the vertical
rod and lifts it, and thus causes the said catch to be lifted and the stop rod to be
released.
The oscillating part is the end of a rod or bar, and the axis of oscillation
of this rod or bar coincides with that of the part known as the "tapering bar"
one end of which is moved up and down by connection with a slot in a bracket
secured to, and moving up and down with the bobbin rail.
The said oscillating part or rod passes through a hole in a stud projecting
from or passing through the end of the said "tapering bar," consequently the
end of the oscillating rod or bar is moved by the end of the "tapering bar" within
the slot, but as the latter acts upon the oscillating part or rod, nearer to its axis
of oscillation as the traverse shortens, it gives to the end of the oscillating rod the
same uniform length of oscillation whether the traverse is long or short, and if a
traverse is given by failure of the changing mechanism to act, greater than that
due to the then position of the "tapering bar" this excess of traverse causes the
end of the oscillating rod or bar to stop the machine by releasing the said catch as
above explained. By another arrangement of mechanism, there is a rod arranged
to slide vertically in suitable brackets from the framing, this rod has two adjustable
inclined bars or edges secured to it so arranged that when the bobbin rail begins
its traverse when the bobbin is empty, a projection from the "tapering bar," where
it enters the bereinbefore mentioned slot in the bracket attached to the bobbin rail,
will just touch or nearly so, the edges of the said inclined bars, at each extreme,
this said projection from the "tapering bar" also touches in like manner the said
inclined bars or edges, when the tapering bar is in the position when the bobbins
are full, and consequently this said projection from the tapering bar will touch or
nearly touch the said inclined bars or edges at both extremes of traverse during the
entire course of filling the bobbins. Should the traverse at any time exceed that
due to the then position of the "tapering bar" the vertical rod to which the incline
bars or edges are secured, is moved either up or down as the case may be, and this
movement operates to release the before mentioned catch.
The vertical bar has or may have a V bracket attached to it adjustably, and
into this V, a bowl enters, which is on a stud in the vertical arm of a bell
crank lever having its fulcrum on a suitable bracket, the horizontal long arm of
which is weighted to press the bowl in the V, therefore if the vertical rod moves
either up or down, the V will cause the long arm of the bell crank lever to lift and
this releases the said catch. There may be a weight, weight lever or spring to
counterbalance the weight of the vertical rod and inclined bars and parts attached
thereto.
The arrangement of the mechanism may be varied without departing from the
principle of action which is to release the stopping mechanism whenever the bobbin
rail traverses to a greater extent than that due to the required taper, to which the
ends of the spools are to be formed.
The improvements above described or a modification thereof are also applicable
to frames where the bobbins have heads, and the traverse of the bobbin rail is
uniform.
Fig. 1 is a back elevation of such parts of a slubbing, intermediate or roving
frame as will be required to explain my invention.
Fig. 2 is a cross sectional elevation of some parts of the mechanism shown in
Fig. 1.
Fig. 3 is a plan view of some parts of the mechanism shown in Figs. 1 and 2.
Figs. 4, 5 and 6 are respectively side, edge and end views of a slotted bar, shown
detached; and
Fig. 7 is an elevation showing an alternative modification. b, is a shaft which
has its bearing at one end in a stand or bracket a³, secured to the one of the lower
rails a, of the frame,

page_text: This shaft b, is rotated by a bevel wheel (not shown) on the shaft b, that gears
with one on a vertical shaft in suitable bearings, which has a drum or pulley upon
it to which one end of a cord or rope is attached, that can wind upon and unwind
from the pulley. The other end of the cord or rope passes over a pulley and has a
weight attached to it which by its descent rotates the vertical shaft, which rotates
the shaft b. The vertical shaft has a toothed wheel upon it that gears with a
toothed rack which actuates the belt guide between the cone drums, so that both
the toothed rack for the cone drums, and the shaft b, are rotated at the same time
at intervals, namely, at each extreme of the traverse of the bobbin rail, when a
change is required to shorten the traverse of the bobbin rail, and change the speed
of the cone drum that drives the bobbins. The parts above referred to are not
shown in the drawings being old and well known.
The exterior of a boss a, projecting from the side of the stand a', fits the hole
in the boss of a casting c, to which a bracket c', is secured by a bolt, and in this
bracket, there is a hole in which a rod or bar can slide, which bar or rod is termed
the "tapering bar" d.
Part of the underside of this bar d; has teeth formed upon it that gear with a
toothed pinion 6, upon the shaft b.
"
The other end of this tapering bar, has an eye or hole for a pin d', that passes
through it and also through slots in a double bracket e, that is to say, a bracket
formed by two slotted plates one opposite the other and connected near the middle
by a parte.
The eye end of the tapering bar d, comes between the two slotted plates forming
the double bracket e, and the pin d', extends through the slots in both plates.
The double bracket e, has a projection, from one side by which it can be
adjusted upon and secured to one end of a bracket e, the other end of which is
bolted to the bobbin rail e, (see Fig. 2).
In Fig. 1 the double bracket e, and the tapering bar d, and connected parts, are
shown in full line in the middle position of their oscillation, when the bobbin rail e*;
is at half traverse and the double bracket e, and part of the tapering bar d, is also
shown in that figure in dotted line at the two extreme positions, namely, their
highest and lowest.
Every time the shaft b, is partly rotated the tapering bar d, is moved so that the
pin d', which is shown at one extreme of the slot, in the double bracket e, is
moved towards the opposite end of the slot and the radius which the pin d',
describes from the axis of the shaft b, is thus reduced at each oscillating
movement.
The bracket or casting c, has two arms c², in each of which there is an
adjusting set screw (not shown), the point of which comes against a pawl or
catch at the extreme of each oscillation, and these catches and other well known
mechanism form an escapement which allows the shaft b, to revolve to the
required extent at each extreme of the oscillation, and the movement which
happens when the shaft b, partly rotates, and from the oscillation of the bracket c,
reverses the position of bevel wheels which give the to and fro traverse motion to
the shaft moving the bobbin rail (e*).
The rod f, extends the length of the frame and is the ordinary stop rod,
sliding in suitable bearings.
There is a lever/', having its fulcrum on a stud f, in a bracket secured to the
roller beam, and near the lower end of the lever f, a latching arm f iB
jointed at, which in one position, latches upon a stud or projection, in
the framing and resists the pull of a helical spring, one end of which is
attached to the lower end of the lever f', and the other end to a stud in. an
arm or bracket uº, secured to the roller beam a'.
"
There is an adjustable collar, on the stop rod f, against which the edge
of the upper arm of the lever comes; as thus arranged the stop rod f, is.
free to be moved to stop the frame and back again to start it, and when the
latching arm, is lifted or released from its stud f, the spring; will act upon

page_text: the lever f'; to move the stop rod ƒ, acting against the collar ƒ', upon it to stop the
frame.
All the mechanism hereinbefore described by letters referring to the drawings
is old and well known.
In order to carry out my invention, I mount a lever g, on a fulcrum stud g',
in the framing, and the free end of this lever is forked (see Fig.) 21 and the
latch lever, enters this fork so that when the arm g, is lifted it lifts the
catch lever, and also falls with it.
To the arm 9, the upper end of a rod or bar h, is jointed, the lower end of
which is guided so as to be free to ascend or descend in a bracket a', secured
to the lower rail a². This bracket a', carries or may carry the fulcrum h³, of
a two armed lever ³, one arm of which passes through a hole or slot in the
bar h, so that when the other arm of this two armed lever h², is depressed, the arm
in the slot will lift the bar h, endways vertically.
To the upper part of the bar h, a projection ³ is attached by a set screw
passing through a slot in the bar h, so that it can be adjusted thereon.
The slotted bar i, shown by Figs. 4, and 6 detached is connected with. the
tapering bar d, one end hooking upon the bracket c', the other end being kept
in position by the head of the pin d', in the eye of the tapering bar d.
This bar, thus oscillates with the tapering bar d, and its end always keeps
the same position and makes the same extent of oscillation for the longest and
shortest traverse of the bobbin rail e, and its upper and lower edges near its
free end just touch or are just clear of the projection ³, and one of the two
arms of the two armed lever h², at each end of the traverse of the bobbin rail e*,
notwithstanding the shortening of the traverse as the bobbins fill, therefore should
the traverse exceed at any time the extent due to the then position of the winding
of the slivers upon the bobbins, the bar h, is lifted and the latch f³, is released and
the frame is stopped.
Fig. 7 illustrates a modification of my invention.
is part of the roller beam, and a², the lower longitudinal rail of the framing
f¹, is a part of the stop lever Figs. 1 and 2 and ƒ³, is the latching arm that comes
against the stud or projection f
is the double bracket shown in its middle position; d, is part of the tapering
bar, and d¹, is the pin passing through its eye.
The dotted circles d³, show the positions of the pin d', at the two extremes during
the longest traverse when the bobbins are empty, and the dotted circles d³, show
the position of the pin d¹, when at the two extremes of the shortest traverse
when the bobbins are full.
a", is a bracket from the roller beam as, having a bearing in it through which the
upper end of the vertical rod k. slides, and a³, is a bracket secured to the lower
rail a', having a bearing through which the lower end of the vertical rod k, slides.
On the rod k, two brackets k', are secured by a set screw when adjusted on the
rod k, and in each bracket, there is a hole for a bolt, by which an arm, can
be secured when adjusted at the required inclination.
At the upper end of the rod k, a V edged bracket, is secured when adjusted
by a set screw, and in the V of this bracket a bowl, comes which is upon a stud
in the short arm of a bell crank lever k, having its fulcrum k', on a stud secured in
the lower part of the bracket aⓇ.
The end of the long arm of the bell crank lever kº, is bent at a right angle and
passes clear on one side of the end of the lever f', and latch f³, but comes under the
latter.
Whether the rod k, ascends or descends, the bowl, is acted upon to cause the
long arm of the lever ", to lift the latch leverf, and stop the machine.
pon the rod, there is a helical spring, resting at its lower end upon the
bracket a', and against the boss of the lower bracket A, at its upper end.
This spring, is only intended to counterbalance the weight of the rod k, and
connected parts in its normal position.

page_text: If the pin d, should traverse at any time to a greater extent than that due to the
then position of the winding on, of the sliver upon the bobbins, it will come against
one or the other of the inclined arms, and move the rod k, up or down as the
case may be and stop the frame.
In frames, say where bobbins have heads and the traverse is of uniform length,
both when the bobbins are empty and when full a stud or pin projection from the
bobbin rail is or may be arranged to act upon the projections and h³, from the
bar h, Figs. 1 and 2, or the arms ³, from the rod k, Fig. 7, so as to stop the frame
in case of excess of traverse at any time.
..
Having now particularly described the nature of my said invention, and in
what manner the same is to be performed, I declare that what I claim is.
1. The combination with slubbing, intermediate and roving or like frames of
mechanism for stopping the frame in the case of excess of traverse in the bobbin
rail, substantially as herein before described.
2. The combination and arrangement of mechanism substantially as and for the
purpose hereinbefore described and illustrated by Figs. 1 to 6 inclusive of the
drawings.
3. The combination and arrangement of mechanism substantially as and for the
purpose herein before described and illustrated by Figs. 1, 2 and 3 of the
drawings, when modified, substantially as hereinbefore described and illustrated by
Fig. 7 of the drawings.
