PROVISIONAL SPECIFICATION.
Improvements in Slubbing, Intermediate, and Roving Frames.
JAMES HEYWOOD 191 Palmerston Street, Manchester Machine Fitter, do
bereby declare the nature of this invention to be as follows:-
It is an improved application of cone drums to the winding mechanism of
slubbing intermediate and roving frames, whereby the irregularity in driving
hitherto arising from the unequal grip of the two edges of strap upon the varying
diameter of the cone drums is considerably reduced.
In performing my invention instead of employing a single pair of cone drums as
heretofore, I use one driving cone drum as heretofore, and two cone drums on
different driven shafts, with a separate strap to each, thus I am enabled to give my
cone straps a better grip, and more reliable driving.
I also claim an arrangement for tightening the said straps independently of each
other, by lowering one or the other of the driven cone drums, by means of
lengthening the connecting links with right and left hand screws.

Improvements in Slubbing, Intermediate, and Roving Frames.
JAMES HEYWOOD 191 Palmerston Street, Manchester, in the County of
Lancashire, occupation, Machine Fitter, 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 :-
Improved application of cone drums to the winding mechanism of slubbing,
intermediate and roving frames, whereby the irregularity in driving hitherto
arising from the unequal grip of the two edges of strap upon the varying diameter
of the cone drums is considerably reduced.
In performing my invention instead of employing a single pair of cone drums as
heretofore I use one driving cone drum as heretofore and two coue drums on
different driven shafts, with a separate strap to each, thus I am enabled to give
my cone straps a better grip and more reliable driving. I also claim an arrange-
ment for tightening the said straps independently of each other, by lowering one
or the other of the driven cone drums by means of lengthening the connecting
links with right and left hand screws.
My invention will be understood from the following description on reference to
the accompanying drawings which are, a front elevation, side elevation, and also a
plan of the two bottom cones.
(Fig. 1.) Front elevation. The top driving cone A. communicates motion
to the two driven cones, B, and, B', which are driven by a separate strap to each,
namely the strap C. drives the cone, B, and the strap, C', drives the cone, B'.
The driving belts or straps are on different diameters on the cone, A, but the
cones, B, and, B' are so designed that they will both run at the same speed as each
other throughout the entire length of the cones.

page_text: I mount my cones, B, and, B¹, on their respective shafts which revolve in suitable
bearings on the radial swing levers, D, and, D', which are placed at both ends of
the cone shafts.
On the same shafts on which are placed my cones, B, and, B₁ are spur pinions, E,
and, E', which gear into the wheel, F, through which motion is imparted to the
bobbin and lifting rail. In Figs. 1 and 2 will be seen how I tighten each strap
independently of each other by means of the right & left handed screw links, G,
and the nuts, G'. I raise both my driven cones simultaneously by turning the
cam H half a revolution, it raises the sliding block, I, which is connected to the
driven cone levers by the links, G.
On the bottom end of the swing levers D and D' are secured the shafts K and K¹
which are stay rods for the cones B and B which rise and fall simultaneously with
the said cones.
And it may be understood that I might place two driving cones at the top in
place of one driving cone, and one driven cone at the bottom instead of two driven
cones and to be acted upon as regards tightening each strap independently, and
the raising of the two driving cones simultaneously the same as before described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
The position of my two driven cones being parallel to one another, and also the
method in which the said cones are mounted as explained above, and the means I
employ or its equivalent in tightening the cone straps, and also if I think fit to
reverse my cones and have two driving cones and one driven cone.
Dated this 4th day of February 1895.
