I SAMUEL TWEEDALE, of Globe Works, Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN APPARATUS FOR VARYING THE SPEED OF THE BOBBINS OF ROVING SLUBBING
AND INTERMEDIATE FRAMES " to be as follows:-
The object of this invention is to assist the cones in driving the pinion on the
driving shaft.
On the driving shaft we fasten a flanged bush, upon the bush is a loose boss,
having angled or flat frictional surfaces pressed into or upon a corresponding
frictional surface formed on the inside or edge of the pinion referred to-the bush
is provided with lugs or locking pieces which engage with, and drive at the same
speed the boss referred to, and which boss has a sliding movement imparted thereto
on its shaft by springs or weighted levers so as to bring its angled or other shaped
frictional part in contact with the frictional part of pinion and as the speed of the
boss is greater than the speed of the wheel driven by the cones the said wheel is in
part driven by contact and rotation of the angled boss.

I SAMUEL TWEEDALE, of Globe Works, Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN APPARATUS FOR VARYING THE SPEED OF THE BOBBINS OF ROVING SLUBBING,
AND INTERMEDIATE FRAMES 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 to assist the cones in driving the pinion on the
driving shaft.

page_text: Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which:
Fig. 1 is a sectional elevation through line A, B, of Fig. 2.
Fig. 2 is an end elevation in section on line C, D, of Fig. 1.
On the driving shaft 1 of the frame is secured by set screw the flanged bush 2
and upon the latter is the loose boss 3 having angled frictional surface 4 pressed
into or upon a corresponding frictional surface 5 formed in the pinion 6, the said
pinion gears with the train of wheels driven by the bottom cone, the bevel pinion 7
gears with the bevel of the differential gear or "Jack," the wheels 6, 7, being the
wheels marked 7 and 6 in drawings of my improved differential gearing illustrated
on Sheet 1 of Specification of Patent No 15,720 dated 29th November 1884-The
flanged bush 2 by means of the head of the set screw 8 (in recess 9 see Fig. 2)
tends to drive the frictional surface 4 at the same speed as the bush 2 and which
angled surface has a sliding motion, or is pressed to the corresponding frictional
surface 5 by means of the spiral spring 10 and as the speed of the flanged bush 2
is greater than the speed of the wheel 6 the latter is in part driven or helped
by contact of the frictional surfaces 4, 5, and so take part of the work off the
cone belt.
An obvious modification would be to mount the boss 3, on shaft 1, latter having
a key thereon so that the boss 3 could slide upon its shaft and the frictional
surfaces be thus brought together by spring or weighting lever but I prefer the
apparatus first herein described.
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. The flanged bush 2, frictional boss 3, frictional wheel 6, all in combination
for purpose and as herein described.
2. The frictional boss 3 driven at the same speed as the driving shaft 1 free to
slide on such shaft, in combination with the frictional surface 5 and wheel 6 as
herein fully described.
