and to Lap Machines.
We JOHN ASHTON Cotton Spinner of Oak House Beal Lane and JOSEPH MOORHOUSE
Mule Overlooker of 25 Blakelock Street both of Shaw near Oldham in the County of
Lancaster do hereby declare the nature of our said invention to be as follows:-
The objection of this invention is an improved application of cone drums to the
winding mechanism of slubbing and intermediate roving Frames and also to the
self feeding regulators of Lap-Machines whereby the irregularity in driving hitherto
experienced and arising from the unequal grip of the two edges of the strap upon the
varying diameter of the cone drums is considerably obviated.
In performing our invention, instead of employing a single pair of cone drums as
heretofore we use two or more cones on the same driving and driven shafts and a
corresponding additional number of cone straps capable of moving simultaneously
and thus we are enabled to use narrower straps than heretofore and yet we obtain a
better grip and a more certain and reliable driving action.

and to Lap Machines.
We JOHN ASHTON of Oak House, Beal Lane, Shaw, near Oldham, Cotton Spinner,
and JOSEPH MOORHOUSE of 25 Blakelock Street, Shaw, near Oldham, Mule Over-
looker, do hereby declare the nature of our invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is an improved application of cone drums to the
winding mechanism of slubbing, intermediate, and Roving Frames, and also to the
self-feeding regulators of Lap Machines whereby the irregularity in driving hereto-
fore experienced and arising from unequal grip of the two edges of the strap upon
the varying diameter of the cone drums is considerably obviated.
In performing our invention, instead of employing a single pair of cone drums
as heretofore, we use two or more cones on the same driving and driven shaft and a
corresponding additional number of cone straps capable of moving simultaneously and
thus we are enabled to use narrower straps than heretofore and yet we obtain a better
and more certain
8n the accompanying drawing, Fig. 1. is a back view of so much of a Roving
Frame as is necessary to explain our improvements which are illustrated applied
thereto, and which improvements are equally applicable to slubbing and intermediate
frames. Fig. 2. is a transverse section of Fig. 1. on line ab. In both views a. and b.
are the upper and lower cone shafts for imparting the varying speed to the winding
and lifting mechanisms.
In accordance with this invention each of these shafts is fitted with a pair of cones
marked respectively c. c. and d. d. and round which cones are passed a pair of driving
belts or straps c¹ and d¹. It will be apparent that, as the cones on each shaft are
exact facsimiles of each other, it will be necessary to ensure their driving belts or
straps occupying constantly the same relative position on each set of cones and that
they shall be moved to and fro along such cones exactly simultaneously. This is
accomplished by lengthening out the usual rack bar g. and by having a pair of strap
forks e. and f. one for each strap c¹ and d¹ affixed thereupon. In this manner we are
enabled to use straps of considerably narrower width and yet to obtain a better grip
upon the cones and consequently a steadier and more reliable driving motion than has
heretofore been practicable with single cones and wider straps. We also find that
frames of considerably greater length can be driven upon this principle.
Our improvements are equally applicable to the self-feeding regulators of Lap
machines and consist in applying a pair of cones upon each cone shaft and which are
driven and operated simultaneously as herein before described-the strap levers (which
are geared together by means of sector wheels in the ordinary way) being fitted in
each case with a double (instead of a single) strap fork so as to move both driving
straps simultaneously along their respective cones.

page_text: . Having thus particularly described and ascertained the nature of our invention
together with the best means with which we are acquainted for carrying the same into
practical effect we wish it to be understood that we do not confine ourselves to the
precise details relative proportions or diameters of the cones and other parts of the
mechanism herein before described and illustrated on the accompanying drawing as
the same may be considerably varied without departing from the invention, but what
we do claim is :-
1st. The improvements in the cone driving mechanism of slubbing intermediate
and Roving Frames and of Lap Machines substantially as hereinbefore described and
illustrated on the accompanying drawing.
2nd. In driving the cone shafts of slubbing intermediate and Roving Frames and
of Lap Machines, the employment of two or more sets of cones mounted and operated
substantially as and for the purposes hereinbefore described and illustrated on the
accompanying drawing.
