IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON OR OTHER FIBRE FOR SPINNING
Year: 1884

page_text: I WILLIAM TAYLOR of 19 Hill Street Oldham in the County of Lancaster
Foreman Mechanic do hereby declare the nature of said Invention for
IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON OR OTHER FIBRE FOR
SPINNING, to be as follows:-
My Invention relates to improvements in slubbing, intermediate, and roving
frames used in preparing cotton or other fibre for spinning and the object of my
improvements is to provide an automatic arrangement for releasing the cone strap
and at the same time holding fast the bottom cone, thus running the roving loose
on the top of the flyers, when the bobbins have attained their full size and before
the frame has completely stopped.
I attain this object by connecting the ordinary knocking off lever by a rod or in
other convenient manner to a catch which holds the cone drum down: when the
strap is moved from the fast to the loose pulley by the knocking off lever, the catch
is released and the bottom cone drum raised by means of a weighted lever, spring
or other mechanical equivalent: the cone strap is thus slackened and the bottom
cone drum is brought into contact with a brake which stops the cone and allows
the bobbins to revolve at the same speed as the spindles and thus as the winding
motion is stopped the roving runs loose on the top of the spindle.

Foreman Mechanic, do hereby declare the nature of said Invention for
"IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON OR OTHER FIBRE FOR
SPINNING" 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 used in preparing cotton or other fibre for spinning and the object of my
improvements is to provide an automatic arrangement for releasing the cone strap
and at the same time holding fast the bottom cone, thus running the roving loose
on the top of the flyers, when the bobbins have attained their full size and before
the frame has completely stopped.
I attain this object by connecting the ordinary knocking off lever by a rod or in
other convenient manner to a catch which holds the cone drum down: when the
strap is moved from the fast to the loose pulley by the knocking off lever the catch
is released and the bottom cone drum raised by means of a weighted lever, spring
or other mechanical equivalent: the cone strap is thus slackened and the bottom
cone drum is brought into contact with a brake which stops the cone and allows
the bobbins to revolve at the same speed as the spindles, and thus, as the winding
motion is stopped the roving runs loose on the top of the flyers.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Drawing which represents
part of a roving frame to which my improvements are applied.
a is the change lever or bracket: 6 61 are the catches: c the connecting rod
and d the lever; these parts are or may be of the ordinary construction and are
operated as usual at each movement of the reversing motion: e is the long rack to
one end of which are secured the cone strap guides e¹ e³: e³ is a weight connected
by a band or chain passing over the pulleys and es to the long rack e: g is
the catch lever connected to the knocking off lever h connected to the stop rod i at
one end of which is secured the strap guide j: I fix or form on the stop rod i a
collar or projection k which when the machine is running rests under the lever k¹
of a brake k³ pivoted at *; when the stop rod is moved to guide the strap on to
the loose pulley, the collar k is moved away from the lever k¹ and the brake k³ is
caused to bear on the driving pulley by the spring (see Fig. 2) and so stops the
machine. The knocking off lever h is connected by a rod to a catch m pivoted
at m¹: this catch m rests on a collar n fixed on the rod n¹ hinged to the bearing nº
of the lower cone drum: o is a weighted lever one end of which rests under the
collar n.
When the bobbins have attained their full size the rack e has moved far
enough to bring the catch f between the end of the catch lever g and the lever c,
the latter releases the catch lever g and allows the lower end of the lever h to be
moved (in the direction of the arrow) by the band and weight, thus moving the
stop rod i and strap guide ; and traversing the driving belt on to the loose pulley:
the collar k is moved away from the lever k' and the brake k is brought against
the driving pulley. When the lever h moves it withdraws (by the rod 1) the
catch m from the collar n and the weighted lever o lifts the lower cone drum
(which turns in swivel bearings) and slackens the cone strap thus allowing the
bobbins to revolve at the same speed as the spindles and causing the roving to run
loose on the top of the flyers.
I fix a brake pulley p on the lower cone drum shaft and fit a brake q near this
pulley when the cone drum is raised the pulley p is brought against the brake q
thus ensuring the instantaneous stoppage of the cone drum.

page_text: By the use of my Invention, the time and labour of lifting the drum by hand
are saved, and sufficient roving is run loose on top of the flyers after the bobbins
have attained their full size to start the frame when the bobbins have been changed
thereby avoiding the delay after changing the bobbins caused by starting and
restarting the frame to run out sufficient roving to lap on the bobbins before the
machine can again be set in operation.
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. Releasing or slackening the cone strap automatically and the mechanism for
effecting the same, substantially as and for the purpose herein specified.
2. The combination with the cone drum bearing of a retaining catch m
connected to the knocking off lever and the weighted lever o or its equivalent,
substantially as and for the purpose herein described and as shown,
