PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Driving the Friction Motion and
Weaver's Beam in Sizing Machines.
I PETER BRIMELOW of 54 Shepard Street, Bury, in the County of Lancaster,
Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention relates to improved combination of appliances to be employed on
machines for purposes aforesaid whereby the cone drums are dispensed with.
According to this my said invention in lieu of the cone drums, I employ on the
axles on which the cones were employed, expanding V driving pulleys, and combine
therewith levers, and links, whereby the pulleys can be set or expanded to the
diameter for imparting the requisite speed to the friction motion of sized or weavers
beam. In the construction of apparatus aforesaid I employ on each axis, two bevelled
discs having arms and spaces, the bevelled surfaces being opposite each other and
form a surface for the driving rope, one of each pair of discs is fast on the shaft,
the other is loose, and by lever and link or by lever and right and left handed screw
or by levers and gear, the loose discs can be moved or caused to slide on their key
and axis, so as to increase or decrease the driving diameter of the respective pulleys,
according as such may be necessary.

Improvements in Apparatus for Driving the Friction Motion and
Weaver's Beam in Sizing Machines.
I, PETER BRIMELOW, of 54 Shepard Street, Bury, in the County of Lancaster,
Mechanic, 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 :-
This invention relates to improved combination of appliances to be employed on
machines for purposes aforesaid whereby the cone drums are dispensed with.
According to this my said invention in lieu of the cone drums, I employ on the
axles on which the cones were employed, expanding V driving pulleys, and combine
therewith levers, and links, whereby the pulleys can be set or expanded to the
diameter for imparting the requisite speed to the friction motion of sized, or weavers
beam. In the construction of apparatus aforesaid I employ on each axis, two
bevelled discs having arms, and spaces, the bevelled surfaces being opposite each
other forming a V surface for the driving belt; one of each pair of discs is fast on
the shaft, the other is loose, and by lever and link, or by lever and right and left
handed screw, or by levers and gear, the loose discs can be moved, or caused to slide
on their key and axis, so as to increase or decrease the driving diameter of the
respective pulleys according as such may be necessary.
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 in which:
Fig. 1. is a side elevation of my improved apparatus for driving the friction motion,
and weavers beam in sizing machines. One of the pullies being represented as
having a larger driving diameter than the other.
Fio. 2 is a detail of part of the apparatus, drawn to an enlarged scale.

page_text: Fig. 3. is a plan view of Fig. 1 but both pullies are shewn with equal size of
driving diameter.
Fig. 4 is a modification of my improved apparatus for expanding, and contracting
the V driving pullies.
Fig. 5 is a sectional elevation of one of the V driving pullies.
According to this ny invention on the axles 1. 1; on which the cones were hereto-
fore employed, I mount expanding, and contracting V grooved driving pullies 2. 2.
which pullies 2. 2. are connected by a driving belt 3 of V section. One half or
portion 2 of each of the pullies 2. 2 is fixed by set screws on the axles 1. 1, the
remaining half, or portion of the pullies 2. 2 have a key bed 4 formed in their boss 5
and are free to slide along the key 6 on the axle 1 when operated upon as hereinafter
described.
Attached to each boss 5 of the pullies 2. 2 is a loose collar 7 carried in a groove
in the boss 5, to this collar 7 is attached by set screws, or otherwise, a forked clip 8
which is formed at one end of a lever 9 carried on a fulcrum stud 10; the other
end of the lever 9 being attached by a stud 11 working in a slot 12 in the lever 13
the latter being carried on a long boss 14, the lower part being fixed to a worm
wheel 15 operated upon by a worm 16 on a shaft 21 turned in either direction, with
the handle 17 by the attendant on the machine.
The worm wheel 15, and lever 13 are free to turn on the pin 18, which pin 18 with
the fulcrum studs 10 and the bearings for the worm 16 are carried on the bracket 19
fixed to the inside of the machine frame 20.
The action is as follows:-
When the shaft 21 and worm 16 are turned, it causes the worm wheel 15 to revolve,
or make a part revolution, and also the lever 13 fixed to it, so that the lever 13 will
move each of the levers 9. 9 on their fulcrum studs 10, the forked ends 8. 8 sliding
the moveable portion, or half of the pullies 2. 2. along the key 6, one nearer to, and
the other further from its corresponding, and fixed portion or half 2ª so that the
driving surface, or diameter of one of the V grooved pullies is made larger, and the
other one smaller in equal ratio, thus the relative speed of the two axles 1. 1 can be
varied, and the driving belt 3 is kept at a sufficient tension without the aid of a carrier
pulley.
An equal amount of lateral motion is given to the forks 8. 8 by their being the
same distance from their respective fulcrum studs 10. 10 and also the same distance
between the studs 10. 10 and the studs 11. 11, the pin 18 being in the middle of the
lever 13.
In Fig. 4 is shewn a modified form of my invention in which both portions or
halves 2. 2 and 2" 2" are made so as to slide on the axles 1. 1 by means of forks 8. 8
levers 9. 9 on studs 10. 10 operating as above described; but in lieu of the worm,
and worm wheel there referred to, i employ a shaft 21 on which is chased a right hand
screw 22 and a left hand screw 23.
When the handle 17 and shaft 21 are turned by the attendant, the screws 22 and 23
acting in opposite directions on the levers 9. 9. the latter are forced apart, or drawn
together, the ends of the same levers 9. 9 at the other side of the fulcrum studs 10. 10
being operated in a reverse direction, that is to say :-If the screws 22. 23 force
apart the ends of the levers 9. 9. nearest to them the two parts, or halves of the pulley
will also be forced apart, but the opposite pulley will be contracted by the same
levers 9. 9 turning on their fulcrum studs 10. 10.
The V grooved driving pullies consist of a pair of bevelled discs 2. 2ª (see Fig. 5)
the bevelled surfaces 24 being opposite to each other, thus forming the V grooves
for the driving belt 3 of V section. The vanes or arms 25 of one of the discs 2
passing between the vanes or arms 26 of the other disc 2ª the centre of each disc
being formed with a boss as ordinary.
Though I have described the apparatus, as employed for driving the friction
motion, and weavers beam of sizing machines, it will be obvious that it is equally
applicable and efficient for driving other machinery.

page_text: Having now particularly described and ascertained the nature and object of my
said invention, and in what manner the same is to be performed I declare that
what I claim is :-
1. The expanding and contracting pullies 2. 2 levers 9. 9 lever 13 worm 16 and
worm wheel 15 all in combination as, and for the purpose herein described, and
substantially as illustrated by Figs. 1 and 3 of the annexed drawings.
2. The expanding and contracting pullies 2. 2 levers 9. 9 and right and left
handed screwed shaft 21. (or equivalent mechanism for operating the pullies) as
herein described and as illustrated by Fig. 4 of the accompanying drawings.
