PROVISIONAL SPECIFICATION.
Improvements in Machinery for Preparing Cotton and other
Fibrous Materials for Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, 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 invention for which Letters Patent
numbered 2664 and dated 4th February 1884 were granted to the late William
Tavlor.
My improvements consist chiefly in an automatic arrangement for raising the
bottom cone and slackening the cone strap and bringing the cone into contact with
a brake and so stopping the bobbins quickly when the driving strap is moved from
the fast to the loose pulley and the bobbins have attained their full size, and the
object of this arrangement is to deliver a short length of sliver after the bobbins
have come to a standstill and the amount delivered depends upon a brake which
acts upon the flywheel on the driving shaft.
In combination with the foregoing arrangement I also employ by preference
an improved mode of mounting and guiding the lower fork of the cone strap
guide.
In carrying my improvements into effect I mount the bottom cone on a short
shaft which is geared to the bobbin shaft and is supported in a frame consisting of
two end levers connected on one side by a rod parallel with the face of the cone,
The two
and on the other side by a heavy bar forming a counterbalance weight.
end levers are fulcrumed at one end on a short shaft connected by gearing to the
cone and also to the bobbins, and at the other end on a stud secured to the
framing, and when the cone is in its normal or working position the counter-
balance weight which always tends to turn the levers on their fulcra, and so lift the
bottom cone, is prevented from doing this by an upright rod retained in position
by a catch connected to the knocking off lever as in the aforesaid Patent.
arrangement the mechanism for releasing the knocking off lever is differently
arranged, as the cone strap traverse rack commonly called the long rack carries
an arrangement of levers which when the long rack has moved far enough are
actuated by a projection on the vertically reciprocating rack which actuates the
bobbin rail, the movement of the levers effecting the release of the knocking off
lever and the lifting of the bottom cone etc.
In this
The upright rod previously mentioned is screwed at its lower end where it
passes through a swivel in a bracket attached to one of the end levers of the
bottom cone frame; on the screwed end of this lever are locknuts by means of
which the bottom cone can be adjusted in position relatively to the top cone; the
locknuts are preferably inclosed in a cap or casing fastened by a padlock to
prevent any unauthorized person tampering with the adjustment. The upper strap
fork is secured to a bar bolted as usual to the end of the long rack but the lower
strap fork is hinged to the bar and its prongs are curved and slotted and through
these slots passes the rod which connects the end levers of the bottom cone frame;
this rod as already stated is parallel to the face of the bottom cone so that the

Improvements in Machinery for Preparing Cotton and other
Fibrous Materials for Spinning.
I, ROBERT TAYLOR, Junior, of Asa Lees and Company Limited, 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 invention for which Letters Patent
numbered 2664 and dated 4th February 1884 were granted to the late William
Taylor.
My improvements consist chiefly in an automatic arrangement for raising the
bottom cone and slackening the cone strap and bringing the cone into contact with
the brake and so stopping the bobbins quickly when the driving strap is moved
from the fast to the loose pulley and the bobbins have attained their full size, and
the object of this arrangement is to deliver a short length of sliver after the
bobbins have come to a standstill and the amount delivered depends upon a brake
which acts upon the fly wheel on the driving shaft.
In combination with the foregoing arrangement I also employ by preference
an improved mode of mounting and guiding the lower fork of the cone strap
guide.
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.
Figure 1 is a back elevation, Fig. 2 an end elevation and Fig. 3 a partial plan
of so much of a slubbing intermediate or roving frame as is necessary for the
illustration of my improvements.
Fig. 4 is an end elevation of Fig. 3, and Figs. 5 and 6 are detail views on an
enlarged scale showing the mode of connecting the upright rod to one of the end
levers of the bottom cone frame.
In the drawings, a designates the bottom cone, 6 the top cone, c the driving
strap, d the lower and d¹ the upper strap fork, e the strap fork guide bar, the conè
strap traverse rack, commonly called the long rack, g the weight connected thereto
to traverse it in one direction, h the building motion which regulates the traverse of
the rack, the reversing rod, the reversing bevels and the upright shaft, the
vertically reciprocating rack which raises and lowers the bobbin rail and k₁ the
pinion on the lifting shaft k which drives the rack j.
In carrying my improvements into effect I mount the bottom cone a on a short
shaft a which is geared by toothed wheels a, a, a, a, with a shaft from which
the speed of the bobbius is regulated and the lifting shaft k is driven. The short.
shaft a' is supported in a frame consisting of two end levers m m³ connected on one
side by a rod n parallel with the face of the cone a, and on the other side by a
heavy bar o forming a counterbalance weight. The end lever m is fulcrumed on
the shaft 7 and the end lever m² is fulcrumed on a stud p secured to the framing p,
and when the cone a is in its normal or working position the counterbalance
weight o, which always tends to turn the levers m m on their fulcra and so lift
the bottom cone a is prevented from doing this by an upright roig retained in

page_text: position by a catch ' pivoted to the frame at p² and connected by a rod ³ to the
knocking off lever r as in the aforesaid Patent.
In this arrangement the mechanism for releasing the knocking off lever r is
differently arranged, as the long rack f carries an arrangement consisting of an
elbow levers fulcrumed to the long rack at f' and provided with an adjustable
finger which when the long rack f has moved far enough is actuated by a.
projection on the vertically reciprocating rack j and as it moves the short end of
the lever s unlatches a catch rod ³ connected to the knocking off lever thereby
effecting the release of the knocking off lever which by the connecting rod
withdraws the pivoted catch and allows the weight o to lift the bottom cone a
which throughout the whole of its movement is maintained with its axis parallel
with that of the top cone b.
7°
When the bottom cone a is moved by the weight o as described a pulley u fixed
on its axis is brought against a brake block w to check its rotation.
The upright rod 9 is screwed at its lower end where it passes through a swivel
on the end lever m¹ of the bottom cone frame as clearly shown in Figs. 5 and 6, on
the screwed end of the rod 9 are lock nuts q¹ by means of which the bottom cone a
can be adjusted in position relatively to the top cone b; the locknuts q¹ are
preferably enclosed in a cap or casing fastened by a padlock 9 to prevent any
unauthorized person tampering with the adjustment. The upper strap fork d' is
secured to the bar e bolted as usual to the end of the long rack f but the lower
strap fork d is hinged to the bar e and its prongs are curved and slotted see Fig. 2,
and through these slots passes the rod n which connects the end levers m m¹ of
the bottom cone frame; this rod n as already stated is parallel to the face of the
bottom cone a so that the fork d is guided and maintained constantly at one
uniform distance from the face of the cone.
Having now particularly described and ascertained the nature of my said'
invention and in what manner the same is to be performed I declare that
what I claim is :-
1. Automatically raising the bottom cone upon the release of the knocking off
lever and maintaining the axis of the bottom cone parallel with that of the top cone-
throughout the whole of its movement substantially as herein set forth.
2. In combination, the bottom cone a, the frame consisting of the end levers mm²
connecting rod n and weight bar o, the upright rod 9, the catch r³, and releasing
mechanism substantially as herein set forth.
3. The combination with the bottom cone a and its frame arranged and operating
as described, of the strap fork & hinged to the bar e and guided by the rod n which
passes through slots in its prongs and so maintains it constantly at one uniform.
distance from the face of the cone substantially as herein set forth.
4. The several combinations and arrangements of parts embodying my improve-
ments in machinery for preparing cotton or other fibrous materials for spinning
substantially as berein described with reference to the accompanying drawings.
