Improvements in Slubbing, Intermediate, and Roving Frames
employed in the Preparation of Fibrous Materials for Spinning.
I, CHARLES FREDERIC AINSWORTH of Lower Brazley, Horwich, in the
County of Lancaster, Cotton Spinner, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in slubbing, intermediate, and roving
frames employed in the preparation of fibrous materials for spinning, and has for its
object the application of an apparatus for preventing the winding back of the rack
operating the belt on the cone drums until the required amount of roving has been
wound on the bobbins.
In carrying my invention into effect I attach to the rack in any suitable manner a rod
or bar, so that as the bobbins fill, the rack and the rod or bar may move together.
To the handle (or other convenient part) of the bottom cone drum lifting arrangement
I fix or cast a snug, finger, or projection over which the rod or bar closely passes.
Notches are cut in the rod or bar to allow the snug, finger or projection on the lifting
handle to pass through, but only at the commencement and the finish of the building
of the bobbin.
The catch levers acting with the catch wheel of the escape motion, I couple or bind
together in such a manner that they may move as one piece, at the same time
making it practically impossible to move them out of gear with the catch wheel.
To any convenient part of the bottom cone drum lifting arrangement I attach a
stud, finger, or projection operating the coupling piece binding the catch levers.
In operation and when the bobbins are fully wound, the rod or bar has moved to its
full extent and brought one of the notches in such a position that the snug, finger,
or projection on the handle of the bottom cone drum lifting arrangement will pass
through and allow the bottom cone drum to be raised.
In raising the bottom cone drum the finger or projection attached to the lifting
arrangement raises the coupling piece binding the catch levers allowing the rack to
be wound back ready for the commencement of winding on a fresh set of bobbins.
In place of cutting notches in the rod or bar, I may employ brackets having notches
cut therein, and arranged to be adjusted on the rod or bar, or, the rod or bar may be
made adjustable, so that the rack may be wound back when any desired length of
roving has been wound upon the bobbins.

the
I, CHARLES FREDERIC AINSWORTH, of Lower Brazley, Horwich, in
County of Lancaster, Cotton Spinner, 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 slubbing, intermediate and roving frames
employed in the preparation of fibrous materials for spinning, and the chief object of
my improvements is to prevent the winding back of the strap fork guide rack, which
regulates the position of the driving belt on the cone drums, until the required
amount has been wound on the bobbins.
I accomplish this object by the arrangement of mechanism illustrated in the
accompanying sheet of drawings.
Figure 1 is a front elevation, and Fig. 2 an end elevation of part of a slubbing,
intermediate or roving frame to which my improvements are applied.
In these views,-a designates the framing of the machine, b the top cone drum,
c the bottom cone drum, and d the driving belt, e the cone strap fork guide rack,
f the pinion gearing into the rack and fixed on the vertical shaft g the movements of
which are regulated as usual by the building motion, h the hand wheel fixed on the
shaft I, i the building or escaped motion ratchet, and k k the catch levers.
All the foregoing parts are of the usual construction and operate in the usual way.
According to my improvements I secure an adjustable plate or bar m by means of
bolts n passing through slots in the plate to the under side of the rack e. This plate m
has two notches m¹ cut in it one near each end to allow a projection o¹ to pass
through but only at the cemmencement and finish of a building of a set of bobbins
when the rack e is at one extremity or other of its traverse. The projection o¹ is
fixed on the lifting handle o which is preferably a T shaped lever fulcrumed at o² and
with the end of one arm connected as usual by a link p to the slotted end of the lever q
which is fulcrumed on the shaft and which supports one end of the bottom
cone drum c. On the shaft r is also fixed near the building motion a lever s on which
is fixed a stud 8¹ and this stud 8' engages a slot in one end of a double armed lever t
which is fulcrumed on a stud u carried by the frame j which supports the vertical
shaft g and the building motion. The other end of the double armed lever t is also
slotted and in this slot lies the end of a lever w which is fulcrumed at k² to the
catch lever k¹. The lever w is bent or notched at w and acts as clearly shown in
Fig. 1, to couple the two catch levers kk together in such a manner that they move
practically as one piece thereby rendering it virtually impossible to move the
catch lever k out of gear with the ratchet wheel i while the lever wis in the position
shewn in Fig. 1.
When however a set of bobbins has been fully wound and the particular notch m¹
in the plate m has been brought by the traverse of the rack e immediately over the
projection of the attendant is able to move the handle o, the projection o¹ passing
through the said notch m' and the bottom cone drum c being lifted by the
connections p q thereby turning the shaft in its bearings and by the lever s moving
the double armed lever t and lowering the lever w thus releasing the catch k. The
attendant can then by means of the hand wheel h turn the shaft g and pinion f and
thus wind back in the usual way the rack e with the driving belt d ready for beginning
the winding of a fresh set of bobbins.
When this has been done the traverse of the rack e will have brought the other
notch m¹ immediately over the projection o¹ thus enabling the attendant to

levers k k¹ and restore all the parts to their normal positions as indicated in Fig. 1.
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. The combination with the cone strap fork rack having a notched plate secured
adjustably thereto, of a projection secured to the lifting handle of the bottom cone
drum, said projection being adapted to pass through the notches in the plate only at
the commencement and finish of winding a set of hobbins substantially as herein set
forth.
2. The combination with the cone strap fork rack, a notched plate secured
adjustably thereto, a projection adapted to pass at the times specified through said
notches and fixed on the handle of the bottom cone drum lifting gear, of a lever
coupling the catch levers together whilst the bobbins are building and arranged to
be actuated by suitable connections from the bottom cone drum lifting gear to release
and recouple said catch levers as the lifting handle is turned all substantially as
herein set forth.
