IMPROVEMENTS IN STOP MOTIONS FOR SLUBBING INTERMEDIATE AND ROVING. FRAMES
Year: 1884

page_text: COMPLETE SPECIFICATION.
I WILLIAM TAYLOR, of 19 Hill Street, Oldham, Lancashire, Foreman Mechanic,
do hereby declare the nature of said Invention for IMPROVEMENTS IN STOP
MOTIONS FOR SLUBBING INTERMEDIATE AND ROVING. FRAMES, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
In slubbing, intermediate and roving frames as at present constructed, when the
bobbin is full the frame is stopped immediately the last layer has been wound on
the bobbin and the carriage is then re-started by hand and allowed to run down &
short distance from the "ridge" of the bobbin so as to wind on a few turns of
roving before doffing the fliers.
.
The object of my Invention is to allow the carriage to run down and wind on
these few layers or turns of roving from the ridge of the bobbin before the frame is
stopped and thus to dispense with the necessity for stopping the frame and then
re-starting it by hand.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Figure 1 is an elevation of the side of a roving frame to which my improvements
are applied. Fig. 2 is an end view of part of the same. Figs. 3, 4 and 5 are
detailed views of the same on an enlarged scale.
I bolt to the long rack a, a bracket b, to which is pivoted the slotted lever c, to
the slotted part of which is secured an adjustable lever d and at the other end of
this lever & is pivoted a catch lever e, which is free to swing in one direction but
is prevented from swinging in the other by the pag or stop piece el bearing on the
lever d: a catch f is fixed on the lifting rack g: h is the ordinary latch lever
connected to the knocking-off motion.
When the bobbins are nearly full the long rack a will have brought the catch
lever e over the lifting rack ginto the position illustrated by Fig. 1 and as the
lifting rack rises the catch fconies under and raises the catch levere (which is
prevented from swinging on its pivot by the peg e¹) and lever & thus raising the
slotted lever o which releases the latch lever, thereby stopping the frame.
The number of layers or turns of roving wound on the bobbins may be increased
or diminished as desired by altering the position of the adjustable lever d in the

page_text: slot of the lever c, and thus either raising or lowering the catch lever e. My object
in constructing the catch lever e as described is that if one of the last changes takes
place so as to bring it under the catch f, the catch lever e will be moved by the
latter, and will swing out of the way thus allowing the lifting rack and catch fto
pass without injury.
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
"

Winding on automatically a few layers or turns of roving from the "ridge
nfter the bobbins are full and before the frame is stopped and the mechanism for 1
effecting the same, substantially 'as and for the purposes herein set forth.
