PROVISIONAL SPECIFICATION.
Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames and like Machines.
We, WILLIAM TATHAM and LOUIS ALFRED PORRITT of Vulcan Works,
Rochdale, in the County of Lancaster, Machine Makers, do hereby declare the
nature of the said invention to be as follows :-
In the frames or machines to which our invention refers, there are cone drums,
and in filling one set of bobbins, the cone belt is traversed automatically and in a
well known manner, from one to the other, end of the cone drums, and when the
set of bobbins is full the machine stops automatically-then the lower cone drum is
lifted by a vertical rod in suitable guides and by a suitable handle in order that the
cone drum strap may become sufficiently slack to allow the strap guide to move
back to the other end of the cones ready to start a fresh set of bobbins. This
moving back of the strap is done by hand, by rotating by a hand wheel the vertical
shaft backwards, that operates to move the strap guide step by step forwards when
filling the set, and besides the friction of the gearing in moving back the strap
guide a heavy weight has to be wound up. The mechanism above referred to are
ordinary parts of slubbing and like frames.
When moving back the strap guide by hand the frame is started to produce
sufficient slack sliver to pass to and round the empty bobbin.
Our invention relates to arrangements for moving the cone strap guide back
automatically while the frame is being worked to produce the slack sliver and
consists in jointing a lever to the vertical bar that lifts the lower cone drum to free
it from the strap, this jointed lover is a catch that can come under a projection ou
the end of the horizontal arm of a bell crank lever on a fulcrum stud secured to the
framing, the vertical arm of which is a clutch fork that acts upon a sliding clutch
on the shaft of the upper cone drum and will bring it into gear with the other half
of a clutch box, that is fast on a shaft in suitable bearings which shaft has a helical
wheel upon it that gears with one fast on the vertical shaft that works the strap
guide intermittently when filling the set.
It will thus be seen that when the vertical rod for raising the lower cone is lifted
and held up by the handle, its jointed catch lifts the end of the bell crank lever
and puts the clutch into gear and when the strap guide is nearly worked back a
finger on the rock bar for the strap guide comes against the lower end of the jointed
clutch lever and releases it from the bell crank lever, the horizontal arın of which
then falls and the clutches are brought out of gear.
If the vertical rod for lifting the lower cone is released too soon, the end of the
jointed catch comes upon a projection from the framing that prevents it from
descending, until the said releasing finger has been drawn fully back.
When the frame is properly at work, the helical wheels drive the clutch shaft
which is free to rotate with the strap guide rack shaft.

Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames and like Machines.
We, WILLIAM TATHAM and LOUIS ALFRED PORRITT, of Vulcan Works,
Rochdale, in the County of Lancaster, Machine Makers, 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 frames or machines to which our invention refers, there are cone drums,
and in filling one set of bobbins, the cone belt is traversed automatically and in a
well known manner, from one to the other end of the cone drums, and when the set
of bobbins is full the machine stops automatically-then the lower cone drum is
lifted by a vertical rod in suitable guides and by a suitable handle in order that the
cone drum strap may become sufficiently slack to allow the strap guide to move
back to the other end of the cones, ready to start a fresh set of bobbins-this
moving back of the strap is done by hand, by rotating by a hand wheel the vertical
shaft backwards, that operates to move the strap guide step by step forwards when
filling the set, and besides the friction of the gearing in moving back the strap
guide a heavy weight has to be wound up.
The mechanism above referred to are ordinary parts of slubbing and like frames.
When moving back the strap guide by hand the frame is started to produce
sufficient slack sliver to pass to and round the empty bobbin.
Our invention relates to arrangements for moving the cone strap, guide back
automatically while the frame is being worked to produce the slack sliver and
consists in jointing a lever to the vertical bar that lifts the lower conc drum to free
it from the strap, this jointed lever is a catch that can come under a projection on
the end of the horizontal arm of a bell crank lever on a fulcrum stud secured to the
framing, the vertical arm of which is a clutch fork that acts upon a sliding clutch
on the shaft of the upper cone drum and will bring it into gear with the other half
of a clutch box, that is fast on a shaft in suitable bearings which shaft has a helical
wheel upon it that gears with one fast on the vertical shaft that works the strap
guide intermittently when filling the set.
It will thus be seen that when the vertical rod for raising the lower cone is lifted
and held up by the handle, its jointed catch lifts the end of the bell crank lever and
puts the clutch into gear and when the strap guide is nearly worked back, a finger
on the rack bar for the strap guide comes against the lower end of the jointed
catch lever and releases it from the bell crank lever, the horizontal arm of which
then falls and the clutches are brought out of gear.
If the vertical rod for lifting the lower cone is released too soon, the end of the
jointed catch comes upon a projection from the framing that prevents it from
descending until the said releasing finger has been drawn fully back.
When the frame is properly at work, the helical wheels drive the clutch shaft
which is free to rotate with the strap guide rack shaft.
Fig. 1 is a back elevation of so much of a slubbing, intermediate or roving frame
as will be necessary to fully explain our invention.
In this figure the lower cone drum and the belt between the upper and lower
cone drums and other parts of the mechanism for carrying out our invention, are
shown in the position they occupy when the frame is working twisting the sliver
and winding it upon the spools or bobbins.
Fig. 2 is also a back elevation of some of the parts shown in Fig. 1, in which the
lower cone drum is lifted to make the belt between the upper and lower cone drums
slack in order that the belt may be moved from that end of the cone drums in
which it is shown in Fig. 2, to that end in which it is shown in Fig. 1, and the
other parts of the mechanism for carrying out our invention are shown in the
position they occupy when operating to effect that object.

page_text: Fig. 3 is an elevation partly in section at a right angle to the plane of the
Figures 1 and 2, and
Fig. 4 is a side, and Fig. 5 a top plan view of a bracket detached which acts as a
stop when secured to the framing for the purpose hereinafter mentioned.
a, is a line representing the ground or floor surface.
a', the uprights of the framing; a², the roller beam.
b, the upper, and 62, the lower cone drums-1, is the axis or shaft of the upper
cone drum, and 63, the axis or shaft of the lower cone drum 2, which has its
bearings in a frame 4, having a shaft or pivots 65, on which it can oscillate in
bearings on the framing (see Fig. 3).
One arm of the frame 6, at one end is slotted, and has a stud secured in it to
which one end of a rod c, jointed, the upper end of which rod passes through and
is guided in a hole in a bracket a³, secured to the roller beam a².
The upper end of the rod, is T headed and has a cross slot c¹ in it that fits a
pin or projection in an arm d, upon a short shaft d², passing through a hole as a
bearing in a projection from the bracket a³.
This short shaft d, has a handle d, secured to it, and it is shown in Fig. 1 in
one position when the rod c, is held down at its lowest position, with the lower conc
drum 62, at its lowest position in which the belt 6, is tight, and this handle d, is
shown in a reverse position in Fig. 2, when the rod c, is lifted and consequently the
lower cone drum 82, is in its highest position when the belt ', is loose and free.
6, is the belt guide and it is secured to the end of a bar e, that can be slided
endways horizontally in suitable guides on the framing, and this bar
has spur
teeth on its side that gear with a spur wheel 1, on a vertical shaft, in suitable
bearings.
e
To a drum, pulley or boss of a wheel on this vertical shaft f, one end of a cord
or chain, is attached, that passes over a pulley ³, in a bracket a', secured to the
framing.
The other end of the cord or chain has a weight ƒ**, suspended upon it.
When the vertical shaft, is rotated one way the cord or chain f", is wound up
and the weight, suspended upon it ascends, and this weight is constantly acting
to rotate the shaft, the reverse way and does so intermittently when permitted by
mechanism which we need not describe as it is ordinary and well known.
The mechanism hereinbefore described by letters of reference is old and well
known and hitherto the cone belt 6, has been moved back by hand at the same
time the vertical shaft, has been rotated so as to wind up the weight.
This
Our invention for automatically moving back the cone belt, and connected
mechanism is effected by prolonging the shaft b', of the upper cone drum b, and
making a separate continuation of it g, arranged in suitable bearings on a bracket a².
The end of the upper cone drum shaft 6, has one half of a clutch box g', loose
upon it, and free to move end ways, but not to rotate except with the shaft.
connection may be effected by a key and key groove in an ordinary manner or as
shown by a collar g, with two pins or side projections from its side, the collar being
secured to the shaft and the pins fit recesses or holes in the boss of the endward
sliding half clutch g', which in one position will gear with its corresponding half
clutch g, secured upon the end of the separate shaft g.
On the other end of the shaft g, a skew or helical toothed wheel g', is secured
which gears with a corresponding wheel y, on the vertical shaft, the boss of
which acts as the pulley or drum for the cord or chain 2.
When the clutch g¹, g, is in gear and the cone drum shaft b, is rotated the
vertical shaft f, is also rotated and the weight, is wound up.
When the clutch ', 93, is out of gear, the shaft y, rotates freely backwards with
the vertical shaft f.
The sliding half y', of the clutch is actuated by the vertical arm of a bell crank
lever g, having a pin from one side of the arm which enters the groove for it in
the sliding half clutch g'.
The bell crank lever g, is upon a fulcrum g', on a bracket a from the framing

page_text: and its horizontal arm has a pin or stud from one side of it, which is acted upon by
a hook catch e, jointed at c³, to a collar secured adjustably upon the rod c.
As shown in Fig. 1 this hook catch, has been moved to one side by an arm or
projection e, secured adjustably upon the bar e, the side of which has come against
the jointed hook catch ².
But when the projection e', is in the position shown in Fig. 2 it is clear of the
jointed hook catch ², which then comes into the position shown in Fig. 2, and
catches upon the projection from the side of the horizontal arm of the bell crank
lever g, so as to lift it when the rod c, is lifted by the handle d, when in the
position shown in Fig. 2.
When the rod c, has been lifted the jointed hook catch ², takes the position
shown in Fig. 2 its end is over a projecting surface formed by the bracket a
(Figs. 4 and 5) which is secured to the framing and the rod . cannot then be
moved down before the jointed hook catch has been pushed to one side by the
projection e, from the bar e, as shown in Fig. 2, because until then the end of
the catch ², will come upon the projecting arm a* of the bracket aº.
In using our improvements the frame "tenter" when the set of spools or bobbins
is full stops the frame, or it is stopped automatically in the ordinary manner, then
the "tenter" moves the handle d, into the position in which it is shown in Fig. 2,
this lifts the lower cone drum 12, and leaves the belt slack and puts the clutch
box g, g, into gear as shown in Fig. 2.
::
Then the tenter starts the frame to produce the required amount of twisted
slack sliver which is to be attached to the empty spool or bobbin which slack sliver
so made is not wound upon the spool or bobbin, but remains above the boss of the
flyer as is well understood, until required.
In producing this slack sliver the shaft 6, is rotated and the bar e, and
consequently the belt guide ³, and belt 7, is moved back from the position shown
in Fig. 2, to that shown in Fig. 1.
The operation of winding back is arrested at the right moment by the projection e¹,
which strikes upon the lower end of the jointed catch e, and releases it from the
horizontal arm of the bell crank lever g, when the weight of this arm or a weight
or spring acting upon it causes the moving half of the clutch g', to come out
of gear.
If sufficient slack sliver is not produced when the clutch y¹, g³, is thrown out of
gear the frame may be kept in motion until there is sufficient sliver.
When sliver is to wind on the spools or bobbins the rod c, is forced down by
moving the handle, into the position shown in Fig. 1 when the cone belt ³,
tightened and rotary motion is transmitted to the bobbins in the ordinary manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
1. The system or mode of automatically winding back the driving belt of the
cone drums when a new set of spools or bobbins is to be filled with twisted sliver
substantially as herein before described.
2. The combination and arrangement of mechanism for automatically winding
back the mechanism and the cone belt when a new set of bobbins is to be filled
with twisted sliver substantially as hereinbefore described and illustrated by the
drawings.
3. The combination and arrangement of mechanism for automatically winding
back the mechanism and cone belt from motion imparted to the frame when forming
slack twisted sliver substantially as hereinbefore described.
