PROVISIONAL SPECIFICATION.
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 mechanism for shifting the cone
driving strap in slubbing, intermediate and roving frames employed in the
preparation of fibrous materials for spinning, and the object of my improvements
is to ensure the cone strap moving the correct distance on the cones.
In carrying my improvements into effect I dispense with the ordinary long rack
and instead I control the movement of the cone strap fork guide rail by means of a
chain or suitable substitute and an expanding pulley.
This expanding pulley would usually be mounted loose on a stud on which is a
toothed wheel geared by a carrier wheel to a toothed wheel secured on the stud on
which the ratchet wheel of the building motion is fixed, although in some cases
the carrier wheel might not be required and in others the pulley might be mounted
upon the same axis as the ratchet wheel.
The expanding pulley. I prefer to employ consists of two discs with their
peripheries bevelled in such a way that when put together they form a grooved
pulley. The toothed wheel on the stud on which the expanding pulley is mounted
has a stud passing through its side and this stud has right and left hand screw
threads cut on it. The discs are tapped, one right and one left, to receive this
screw so that by turning it the discs can be moved nearer to or farther from one
another. The chain (or equivalent) which lies in the groove of the expanding
pulley is attached at one end to the cone strap fork guide rail and at the other end
to the said pulley so that by adjusting the discs the depth of the groove can be
regulated and the axial movement of the pulley caused to let off more or less
chain as required.
The discs composing the pulley might be of volute form or snail shaped so as to
allow a gradually decreasing or increasing movement to be given to the cone strap
fork guide rail.
I prefer to use two adjustable discs as described but one disc might be non-
adjustable and the other be moved by a single screw; or instead of a grooved
expanding pulley I might employ an adjustable conical drum to which one end of
the chain or equivalent is secured and retain the chain on the desired diameter by
means of suitable guides, stops or abutments.

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 mechanism for shifting the cone
driving strap in slubbing, intermediate and roving frames employed in the
preparation of fibrous materials for spinning, and the object of my improvements
is to ensure the cone strap moving the correct distance on the cones.
In carrying my improvements into effect I dispense with the ordinary long rack
and instead control the movement of the cone strap fork guide rail by means of a
chain or suitable substitute and an expanding pulley.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying three sheets of drawings reference being
had to the figures and letters marked thereon.
Figure 1 is an end elevation and Fig. 2 a front elevation of part of a slubbing,
intermediate or roving frame fitted with my improvements and Fig. 3 is a detail
view of part of the mechanism.
Figs. 4 and 5 are views of an alternative construction of expanding pulley
arranged according to my improvements.
In the drawings, a designates the cone strap fork guide rail and a¹ a stud fixed
on the same, and to which one end of a chain 6 or equivalent is attached, the other
end of the chain 6 being connected to the expanding pulley C. The expanding
pulley C is mounted loosely on a stud d on which is also mounted loosely a toothed
wheel e geared by a carrier wheel to a toothed wheel g secured on the stud / on
which the ratchet wheel i of the building motion is also fixed, although in some
cases the carrier wheel f might not be required and in others the pulley C might
be mounted upon the same axis as the ratchet wheel i. The expanding pulley
I prefer to employ is illustrated in Figs. 2 and 3 and consists of two discs c² ² with
their peripheries bevelled in such a way that when put together they form a
grooved pulley. A stud j with right and left hand screw threads cut upon it
passes freely through the side of the toothed wheel e and the discs c¹² are tapped,
one right and one left, to receive respectively the reversely threaded portions of
the stud which is prevented from moving lengthwise by means of the fixed
collars j¹³.
The discs cc forming the expanding pulley and the toothed wheel e are free to
revolve together on the stud d but the wheel e is prevented from moving
independently because of the screwed stud j and is also prevented from moving
transversely by the collars d' d' which are fixed on the stud d consequently when
it is required to increase the traverse of the cone strap k on the cones m m' at
each change of its position the screwed stud j is rotated by a handle applied to its
squared end in such a way as to cause the discs c' c² to approach one another
and so by forcing the chain b to lie on a circle of larger diameter to give out more
length for the same axial movement of the discs. In like manner to reduce the
traverse of the cone strap k the screwed stud j is rotated in the opposite direction
thus causing the discs c'e' to move away from each other and so reducing the
diameter of the circle upon which the chain b lies.
The cone strap fork guide rail a has a rope n secured to it which passes under
and over guide pulleys n' n² and has a weight n³ attached to it and the weight n³

page_text: and rope n traverse the rail a in the usual way whenever one of the building
motion catches is moved out of gear with the ratchet wheel in the ordinary
manner well understood and until the ratchet wheel i is arrested by the other
catch.
The discs c¹² composing the pulley C might be of volute form or snail shaped
so as to allow a gradually decreasing or increasing movement to be given to the
cone strap fork guide rail a. I prefer to use two adjustable discs c¹ c² as described
but one disc night be non-adjustable and the other be moved by a single
screw.
Instead of the grooved expanding pulley CI might employ the arrangement
illustrated by Figs. 4 and 5 in which the stud d is fixed to the framing and on it
are mounted and free to revolve the toothed wheel e, a single flanged disc e³ and a
drum or pulley o but the wheel e and the disc care prevented from moving along
the stud by means of the collars d' d' fixed thereon. The pulley o has a conical
periphery to which is fastened one end of the chain or its equivalent such as a
wire rope b and this rope which lies partially around the periphery of the pulley o
abuts against a series of sliding brackets p which are arranged radially on the
disc around the stud d from which they are equidistant. The brackets pare
pressed against the coned pulley o and towards their common centre the stud d by
a coiled spring 9 which encircles them, they are guided by screwed studs which
slide in slots c in the disc e and the spring q is held in place by a ring c¹ which is
secured to the flanged disc c and so acts as a cover.
The rope b is caused to lie on a greater or smaller diameter as required by
actuating the screwed stud ; and so screwing the coned pulley o into which it is
threaded nearer to or farther from the disc c.
It will be readily understood that the chief advantage obtained by the use of
an expanding pulley according to my invention is that I am enabled to let off
any desired length of chain and so to ensure the movement of the cone strap
fork guide rail and the traverse of the cone strap for the exact distance required
and consequently I am able to obtain a much nicer and more accurate adjustment
than is possible with the ordinary rack and gearing.
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. In a slubbing, intermediate or roving frame dispensing with the ordinary long
rack and instead controlling the movement of the cone strap fork guide rail and
the traverse of the cone strap by means of a chain or suitable substitute and an
expanding pulley or equivalent device the axial movement of said pulley or
equivalent device being regulated by the building motion, all substantially as
herein set forth.
2. The combination with the ratchet wheel and catches of the building motion,
of an expanding pulley or equivalent device connected by a chain or the like to
the cone strap fork guide rail in such a way as to control its traverse, the axial
movement of said pulley or equivalent device being controlled by the building
motion ratchet and catches all substantially as herein set forth.
3. The several combinations and arrangements of parts embodying my
improvements substantially as herein described and
as illustrated by the
accompanying drawings.
