PROVISIONAL SPECIFICATION.
Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames and like Machines:
I, WILLIAM TATHAM, of Park House, Drake Street, Rochdale, in the County
f Lancaster, Machine Maker, do hereby declare the nature of the said invention,,
o be as follows:-
My invention relates to improvements upon or applicable to that invention for
which Letters Patent were granted to myself and Louis Alfred Porritt
numbered 20592 and dated the 26th day of November A.D. 1891, which invention
relates to arrangements for moving the cone strap guide back automatically while
the frame is being worked to produce the slack sliver for the next set of spools or
bobbins to be filled, and my present invention relates to and consists in certain
improvements to be combined with the mechanism described in the Complete
Specification of the aforesaid Letters Patent, namely
1:
1. There is a rod c, described in the said Complete Specification which is actuated
by a handle d, on a short shaft d, on a bracket on the roller beam a².
The lower end of the rod c, is jointed with a frame *, carrying the bearings for
the lower cone drum b.
This frame b', has to he lifted when the belt b', has to be moved along the cone
drums to leave the belt ', slack in order that this may be done.
This belt b', may become slack or tight in working, and my present invention
consists in providing means by which the rod c, may be adjusted in length in order
to put the proper tension upon the cone belt b', and this is or may be effected
according to my present invention by dividing the lower part of the rod c, into
two, and forming a socket on one part for the end of the other part to enter,
which when adjusted is secured by a set screw or by using a coupling with two set
screws, or by screwing the end of one part of the rod with a right hand screw
thread and the end of the other part of the rod with a left hand screw thread and
uniting the two by a right and left handed screw coupling which may be locked
when adjusted by a screw nut on one or both parts of the rod.
Or the lower end of the rod c, may be made to pass more or less through a
swivel part jointed to the traine 6, and when adjusted may be secured by a set
screw.
I
Or the lower end of the rod c, may be screw threaded and passed through the
hole in the swivel part and then may be adjusted in length by a screw nut on the
rod c, above and below the swivel part.
2. When the frame b', for the lower cone drum 62, is tightened and slackened by
5 levers and connections in front of the frame-the upper part of the rod c, and the
handle d, and connected parts are dispensed with, but the rod c, is retained from a
little above the collar c, upon it and it is arranged to slide up and down in a hole
in a suitable bracket on the framing.
With this arrangement either of the modes herein before described are used for
0 adjusting the length of the rod c, between the frame 6, for the lower cone drum
and the said collar c*.
In some cases a bracket is used as a stop for the lowest position of the rod c, i

page_text: which case the rod c, is simply connected with the frame 64, and the rod c, is then
allowed to slide through the collar c³, when being adjusted and when adjusted the
set screw is tightened to secure the collar c³, to the rod again.
3. Another improvement according to my present invention consists in dispensing
with the adjustable stop e', on the sliding rod e, for the belt fork 68, and in causing
the side of the belt fork 68, or an adjustable projection from it to act in place of
the adjustable collar e¹.
4. Another improvement according to my present invention consists in dispensing
with the helical toothed wheels g, and 9, (Figs. 1 and 3) and using a bevel toothed
wheel on the shaft g, to gear with a bevel wheel on a vertical stud in the framing,
this bevel wheel on the vertical stud having a spur toothed wheel on its boss to
gear with one on the vertical shaft f, (Figs. 1 and 3), this arrangement of gearing
allows of the introduction of change wheels so that the quantity of slack sliver for
connection to the next set of spools or bobbins to be filled may be regulated as
desired. When the axes of shafts g and, are in a line bevel wheels only are
required.

Improvements in or applicable to Slubbing, Intermediate, and
Roving Frames and like Machines.
I, WILLIAM TATHAM of Park House, Drake Street, 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 :—
My invention relates to improvements upon or applicable to that invention for
which Letters Patent were granted to myself and Louis Alfred Porritt
numbered 20592 and dated the 26th day of November A.D. 1891, which
invention relates to arrangements for moving the cone strap guide back
automatically while the frame is being worked to produce the slack sliver for the
next set of spools or bobbins to be filled, and my present invention relates to and
consists in certain improvements to be combined with the mechanism described in
the Complete Specification of the aforesaid Letters Patent, namely:-
1. There is a rod c, described in the said Complete Specification which is actuated
by a handle d, on a short shaft d³, on a bracket on the roller beam a².
The lower end of the rod c, is jointed with a frame 64, carrying the bearings for
the lower cone drum b.
This frame 4, has to be lifted when the belt 7, has to be moved along the cone
drums to leave the belt 6', slack in order that this may be done.
This belt b', may become slack or tight in working, and my present invention
consists in providing means by which the rod c, may be adjusted in length in order
to put the proper tension upon the cone belt 6', and this is or may be effected
according to my present invention by dividing the lower part of the rod c, into
two, and forming a socket on one part for the end of the other part to enter, which
when adjusted is secured by a set screw, or by using a coupling with two set screws,
or by screwing the end of one part of the rod with a right hand screw thread and
the end of the other part of the rod with a left band screw thread and uniting the
two by a right and left handed screw coupling which may be locked when adjusted
by a screw nut on one or both parts of the rod.

page_text: Or the lower end of the rod c, may be made to pass more or less through a
swivel part jointed to the frame 64, and when adjusted may be secured by a set
screw.
Or the lower end of the rod c, may be screw threaded and passed through the
hole in the swivel part and then may be adjusted in length by a screw nut on the
rod c, above and below the swivel part.
2. When the frame 6, for the lower cone drum 63, is tightened and slackened
by levers and connections in front of the frame, the upper part of the rod c, and
the handle d, and connected parts are dispensed with, but the rod c, is retained
from a little above the collar c³, upon it and it is arranged to slide up and down in
a hole in a suitable bracket on the framing.
With this arrangement either of the modes herein before described are used for
adjusting the length of the rod c, between the frame 64, for the lower cone drum
and the said collar c³.
In some cases a bracket is used as a stop for the lowest position of the rod c, in
which case the rod c, is simply connected with the frame ; and the rod c, is then
allowed to slide through the collar c³, when being adjusted, and when adjusted the
set screw is tightened to secure the collar c³, to the rod again.
3. Another improvement according to my present invention consists in dispensing
with the adjustable stop e¹, on the sliding rod e, for the belt fork 68, and in causing
the side of the belt fork 68, or an adjustable projection from it to act in place of
the adjustable collar e'.
4. Another improvement according to my present invention consists in dispensing
with the helical toothed wheels 9, and 9, (Figs. 1 and 3) and using a bevel toothed
wheel on the shaft g, to gear with a bevel wheel on a vertical stud in the framing,
this bevel wheel on the vertical stud having a spur toothed wheel on its boss to
gear with one on the vertical shaft f, (Figs. 1 and 3) this arrangement of gearing
allows of the introduction of change wheels so that the quantity of slack sliver
for connection to the next set of spools or bobbins to be filled may be regulated as
desired. When the axes of shafts g and f, are in a line, bevel wheels only are
required.
Fig. 1, is a back elevation of so much of a slubbing, intermediate or roving
frame as will be necessary to explain my present improvements-this Figure 1
being similar to Fig. 1 of the drawings of the Complete Specification of the
aforesaid Letters Patent No. 20592 of 1891 except where modified to illustrate my
improvements, and the same letters and figures of reference as are used on similar
parts in the aforesaid specification are also used on the same parts shown in Fig. 1,
of this specification.

a, ground or floor line.
a uprights of the framing; a², the roller beam; b, part of the upper, and b³,
part of the lower cone drums-b', axis or shaft of the upper, and 73, the axis or
shaft of the lower cone drums, which axis of the lower cone drum has its bearings
in a lever frame 64, having a shaft or pivots on which it can oscillate in bearings on
the framing as shown in Fig. 3, of the aforesaid specification.

secured to the roller beam a².

page_text: +
There is a crank arm on the short shaft d, the pin of which enters a slot c¹, in
the upper end of the rod c, guided in its vertical movements by a bracket a³.
c, is a collar secured on the rod c, by a set screw, this collar having a pin on
one side forming the fulcrum of the catch lever c, the lower end of which when
the catch is lifted rests upon a projection a*, from the table bracket aº.
The hook of the catch e, comes against the projection from one side of the bell
crank lever g, which has its fulcrum g', on a bracket aº. The vertical arm of this
bell crank lever actuates the clutch g', which is connected to slide endways on the
shaft b, by a collar g³, secured upon the shaft as explained in the aforesaid
Complete Specification.
.
93, is the other part of the clutch on a shaft g, in bearings in a bracket a.
³, is a cord or chain passing over a guide pulley f³, in bearings in a bracket a*.
To the lower end of this cord or chain the weight is attached which weight is
wound up when the belt guide is moved back ready to fill a fresh set of bobbins or
spools. is a wheel on the shaft f, for turning it when required by hand.
According to one modification of my present improvements the rod c, is formed
in two parts c and e-the lower end of the rod c, is formed into a socket cb, fór
the upper end of the rod c, to fit into and when adjusted the rod c*, is secured into
the socket cb, by a set screw c°.
Fig. 2, shows a modification formed by one long loose collar cd, to secure
together the lower end of the rod c, and the upper end of the rod by set
screws c°.
Fig. 3, shows another modification in which the lower end of the rod C, is screw
threaded in one direction and the upper end of the rod c, is screw threaded in the
opposite direction to fit the ends of a correspondingly screw tapped long collar ce,
by rotating which the combined length of the rods can be increased or diminished
and when adjusted the right and left handed screw coupling co, is secured by lock
nuts. of
Figs. 5 and 6, illustrate another modification. There is a swivel part c, having
pivots c", placed in forks in the end of an arm 6, from the lever frame for the
lower cone drum 62, and secured in the forks by pins c', across the forks, or the
pivots ch, may be held in any other convenient manner, or the swivel part c³, may
have a pivot c, on one side only to fit a hole in the arm b, and may be secured in
such hole by a pin or other means.
The rod c, in this modification is made in one piece and slides through a hole
in the swivel piece c, and when adjusted is secured by a set screw as shown.
Fig. 4, shows a swivel piece arranged in a similar manner to that above explained
in reference to Figs. 5 and 6. The lower end of the rod c, formed in one piece in
this case is screw threaded and passes through a hole in the swivel piece c, and
there is a screw nut c', on the rod c, above and below the swivel piece by which
adjustment is made.
Fig. 8, illustrates an arrangement applicable when the lever frame carrying the
axis or shaft of the lower cone drum 6, is lifted and lowered by an ordinary
method dispensing with the handle d, and upper end of the rod c.
There is by this ordinary method of lifting and lowering the lever frame for
the lower cone drum 62, an upright arm from the axis 6, of the lever frame (see
Fig. 3 of the aforesaid Complete Specification), and to the upper end of this arm
one end of a horizontal rod is jointed the other end of which rod being formed
into a handle that comes to the front of the machine. This horizontal rod say, on
its lower side near the handle end has a hook or projection to catch upon a
projection from the framing to hold the lever frame for the lower cone drum at its
highest position, this highest position giving sufficient space and slack for the belt
in all degrees of tightness.
On the rod there is or may be another projection which is or may be adjustable
in the lengthway of the rod, this will catch upon the projection on the framing to
hold the lever frame for the lower cone drum down, and give the belt the required
degree of tightness which will vary.

page_text: Instead of this projection on the horizontal rod being adjustable it may be fixed
nd arranged to catch upon an adjustable projection on the framing for it.
The rod c, in this modification may be made in one piece as shown in Fig. 8, its
ower end jointed to the arm of the lever frame and the upper end slides freely in
bracket as, attached to the framing.
When the tightness of the cone drum belt 67, is to be adjusted by this
rrangement the adjustable catch projection on the horizontal handle is changed
n position as required to give the desired tightness to the belt, and the set screw
s unscrewed to release the collar c³, from the rod c, the catch c³, is then lifted
until its lower end rests upon the upper surface of the bracket a*, in which position
the hook of the catch c³, will come under the side projection on the end of the
horizontal arm of the bell crank lever 96, and will thus hold the clutches g¹ and g³,
in gear, then the horizontal rod handle is released and the lever frame is lifted
and with it the rod e, then the set screw of the collar c³, is tightened to secure it
to the rod c, and when the lower end of the catch c³, is pushed from the supporting
projection a*, the lever frame may be moved to the position when the belt is at
work and each time afterwards when the lever frame is lifted to its highest position
(which is constant) the latch c³, will properly perform its functions.
The modification illustrated by Fig. 8, may be used with fixed notches or holding
parts on the horizontal handle rod without disconnecting the collar c³, from the
rod c, by making the rod c, in two parts c, and c, arranged according to either of
the modifications shown by Figs. 1, 2, 3 and 4 or 5 and 6.
In place of the horizontal handle rod connected to an upright arm from the axis
of the lever frame there may be a rod similar to the vertical rod c, and actuated
by a handle d, and crank similar to that shown in Fig. 1, the rod in this case being
horizontal.
The bracket carrying the short shaft d³, in this case would be adjustable in the
direction of the lengthway of the rod on another bracket by a slot and bolt or
bolts by which means the belt could be tightened and slackened when required by
unscrewing the bolt and moving the bracket and thus the rod and lever frame as
required, then when the handle d, is moved to the position to slacken the belt, the
collar c³, will have to be adjusted accordingly as before explained, and then
secured to the rod by the set screw.
The last described arrangement can also be used in the arrangement shown in
Fig. 1, when the rod c, is all in one piece and jointed at its lower end to the arm
from the lever frame.
The part carrying the bearings of the short shaft d', in this case is made
separate from the bracket or stand so as to be adjustable vertically or in the
lengthway of the rod c, by a slot and bolt by which it is secured to the stand
bracket attached to the roller beam a³.
Or the stand bracket is arranged to be adjusted vertically on the roller beam a³,
in the direction of the lengthway of the rod c.
The collar, will have to be released from the rod c, and then secured to it
again when the rod c, is in its highest position with the lower end of the catch c³,
5 resting upon the projection a*, as before explained.
The collar c³, may be left to slide up and down the rod c, but so as not to turn
upon it and there may be an adjustable collar or screw nut on the rod c, to come
against and lift it when required.
0 may
By another modification the rod c, with the handle d, and other connected parts
be arranged as shown in Fig. 1, except that the rod c, is in one piece (as in
Fig. 1 of the aforesaid Complete Specification) and except that the slot c', at the
top of the rod c, is made sufficiently wide to be clear of the crank pin in the arm
on the end of the short shaft d², when in the position shown in Fig. 1, and also
except that the crank pin in this case does not push down the rod c, to hold the
5 belt tight when at work, this being effected by a sufficiently strong helical spring
upon the rod c, abutting against the under side of the bearing a³, at its upper end
and against the upper side of the collar c³, or a separate adjustable collar on the

page_text: rod c, at its lower end, such helical spring acting to force down the rod C, without
obstruction from the crank pin, so that by the weight of the rod c, and other
.connected parts the lever frame 6, and the cone drum 6, and the helical spring the
belt will be kept tight whether it increases or diminishes in length.
When the handle d, is turned to the reverse position to that shown in Fig. 1, the
-crank pin is then above the shaft d, and it will have lifted the rod c, to its highest
position to give sufficient slackness to the belt and as the rod c, will always be lifted
to the same height the collar c³3, therefore may remain fixed when once adjusted.
This arrangement is also applicable when the lever frame is actuated by a
horizontal rod connected with a vertical arm from the lever frame as hereinbefore
explained.
e, is a set screw screwing into the belt guide arm 68, or into an arm from it,
when adjusted it is secured by a lock nut. The end of this set screw e, comes
against the edge of the jointed latch c³, and pushes its end from the projection a*,
when the belt guide is fully back to its position for starting a new set of spools or
'bobbins. This arrangement is a substitute for the stop e', described in the
aforesaid specification.
The fourth improvement is illustrated by Figs. 1 and 7. 91, is a bevel wheel
secured on the end of the shaft g, which gears with a bevel g³, loose on a vertical
stud g, secured in an arm from the bracket a'. This latter bevel g², has a spur
wheel g, attached to it that gears with one go, on the shaft f, to which spur a drum
is attached for the cord or chain f³.
The required direction of rotation will be obtained to suit the arrangement of
the mechanism by placing the bevel wheels as shown in Figs. 1 and 7, or by
making the bevel 92, which is shown to gear with the bevel wheel g', on its lower
side to gear with it on its upper side.
When the shafts 9 and f, are in the same plane bevel wheels only are required.
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 of arrangements with the rod c, and lever frame 6, for
adjusting its position substantially as and for the purpose hereinbefore described
and illustrated by the drawings Figs. 1, 2, 3, 4, 5 and 6.
2. The combination of the rod c, with the lever frame (4) when it is actuated
by a vertical arm from its axis or shaft and connected mechanism substantially as
and for the purpose herein before described and illustrated by reference to Fig. 8,
of the drawings, also the above combination when the connection between the rod c,
and the lever frame &, is adjustable in length by any of the arrangements herein-
before described and illustrated by reference to Figs. 1 to 6 inclusive of the
drawings.
3. The combination and arrangement by which the bearings for the shaft d²,
Fig. 1, or its equivalents, whether acting upon the vertical rod c, Fig. 1, or an
equivalent horizontal rod for giving movement to the lever frame &, are made
adjustable in the length of the rod.c, so that it is only necessary to adjust the
collar c³, on the rod c, substantially as and for the purpose herein before described.
4. The combination and arrangement of the rod e, actuating handle d, and its
crank or equivalent so as only to move the rod c, positively to slacken the belt
which is tightened when the handle is reversed by a helical or other suitable
spring substantially as and for the purpose herein before described.
5. The combination of an adjusting screw e, with the belt guide or an arm from
it, the end of this screw pushing the end of the hinged latch c³, from its support a*,
when the belt is fully back for a new set of spools or bobbins substantially as and
for the purpose herein before described and illustrated by reference to Fig. 1 of the
drawings.
6. The combination and arrangement by which rotary motion can be transmitted
from the shaft g, to the shaft f, in such manner that change wheels can be

page_text: introduced in order to vary the number of turns the shaft g, may have in moving
the belt from one extreme to the other substantially as hereinbefore described and.
illustrated by the drawings.
