I JAMES MACQUEEN of Bury in the County of Lancaster Machinist do hereby
declare the nature of my invention for "IMPROVEMENTS IN MACHINERY FOR PRE-
SUBSTANCES FOR SPINNING and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to improvements in slubbing intermediate and roving
frames used in preparing cotton or other fibrous substances for spinning, and the
object of the invention is to provide an automatic arrangement for stopping the
"winding on "and locking the starting rod in position when the bobbins have
acquired their full size.
In order that my invention may be clearly understood I have annexed hereto
a drawing which shows so much of a roving frame as is necessary for the illustration
thereof.
I mount the top cone drum a, a loosely on the shaft b which is driven in the
usual manner by gearing not shown on the drawing, c is one half of a clutch
attached to the top cone drum a.
The corresponding half c¹ of the clutch is mounted on a feather or key on the
shaft b. The clutch c¹ is provided with a grooved boss into which takes the forked
end of a lever d, d which I connect by a suitable rod a, a to the usual knocking off
lever f.f.
The lower end of the lever f, f is provided as usual with an arm g, g which is
raised in the ordinary way when the bobbins have attained their full size by the
incline h, h on the sliding rack i, i to which the cone strap forks are attached.
To a convenient part of the frame I attach a stud upon which I mount a catch
k, k* provided with a cover l, to prevent it from being tampered with.
When the incline h, h on the rack i, i has moved beneath the arm g, g and
raised it the spring m m pulls back the lever f, f and moves the starting rod n, n
thereby throwing the driving strap onto the loose pulley in the usual way.
The arm gg has also been moved laterally and the catch k, k* then falls into a
notch in the arm g, g (as shown by dotted lines in the drawing) and locks the
starting rod in this position.

page_text: The movement of the lever ff has also withdrawn the clutch c¹ from the clutch c
by means of the connecting rod e, e and lever d, d thereby stopping the top cone a
and the "winding on " and allowing the yarn to run slack on the flyer.
When the arm is replaced into the position shown by the full lines on the
drawing the catch k, k¹ cannot follow it as the tail piece k*, rests against the fixed
cover l, l
The ordinary break may of course be applied by the knocking off rod which is
actuated by the lever f, f in the usual way.
It will also be evident that this clutch mechanism may be applied to any wheel
of the train of gearing between the top cone shaft and the "winding on."
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
First. The use or employment in slubbing intermediate and roving frames of a
clutch or its equivalent actuated substantially as described and illustrated for
stopping the "winding on" preparatory to "doffing."
Secondly. The use or employment in such frames of a catch substantially as
shown and described for locking the "starting rod.”
