IN APPLIANCES, FOR BALANCING THE TOP RAIL, AND FOR RAISING AND LOWERING
THE BOTTOM CONE, OF ROVING, AND SLUBBING FRAMES, to be as follows:-
:-
This invention consists, of improved apparatus for securing the balance of the
top or lifting rail, of roving and slubbing machinery, and for purpose of raising and
lowering the bottom cone, of such inachinery, to facilitate the transfer, of the strap
to opposite end of the cone, for purpose well understood, and also facilitating the
splicing, or taking up such strap, when necessary.
For purpose of ensuring the balance of the lifting rail, I employ a lever, the
fulcrum of which is formed by, and is free to move in a slot, formed in a bracket,
attached to the back of the frame, and at a point as near the lifting rail as prac-.
ticable, I attach to the said lever, one end of a chain, which is thence carried to a
pulley, on the end of a short cross shaft, and on which shaft is also another pulley,
but of larger diameter, than the one referred to, or a lever, and from which pulley
or lever, is suspended a balance weight, the other and inner end of the said lever
first herein referred to, being immediately under the centre of the lifting rail, and
by reason of the variation in the diameters of the two pulleys, or the one pulley
and the lever, as the case may be, I secure increased efficiency from a given weight,
and a direct application of lifting or balancing power, to the said lifting rail.
I lift and lower the bottom cone, by means of a vertical shaft, at the back of the
'frame" and operated by a handle from the front of the frame-At the foot of the
said shaft is a segment wheel gearing with a pinion wheel, in which is a crank pin,
the latter being received and working in a slot, formed in the lever connected with
the carrying bracket, or arm for supporting the bottom cone in position-When the
vertical shaft is turned, its segment operates the pinion and crank pin, turning the
slotted lever connected therewith, equal to the throw of the crank pin, which is
thus brought to a dead centre, locking the several parts, and the cone, in the raised
position, a reversal of the handle places the cone in the lower, and the several parts
in their normal position.

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 APPLIANCES FOR BALANCING THE TOP RAIL, AND FOR RAISING AND LOWERING
THE BOTTOM CONE OF ROVING AND SLUBBING FRAMES and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:—
"
This invention consists of improved apparatus for securing the balance of the top
or lifting rail of roving and slubbing machinery and for purpose of raising and
lowering the bottom cone of such machinery to facilitate the transfer of the strap
to opposite end of the cone for purpose well understood and also facilitating the
splicing or taking up such strap when 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
forming a part of this specification in which :--
Fig. 1 is a side elevation partly in section of my improved apparatus for balancing
the top rail.
Fig. 2 is a back elevation of same.
Fig. 3 is an end elevation for raising or lowering the cones.
Fig. 4 is a plan view of the same.
For purpose of ensuring the balance of the lifting rail 1 I employ a lever 2 the
fulcrum 3 of which is formed by and is free to move in a slot 4, formed in a
bracket 5, attached to the back of the frame 6, and at a point, as near the lifting
rail 1, as practicable, I attach to the said lever 2 the end of a chain 7 which is
thence carried to a pulley 8, on the end of a short cross shaft 9, and on which shaft
also is another pulley 10 but of larger diameter than the one referred to, and from
which pulley (or lever) is suspended a balance weight 11, the other and inner end 12
of the said lever 2, being immediately under the centre of the lifting rail 1 and by
reason of the variation in the diameter of the pulleys 8 and 10, is secured increased
efficiency from a given weight and a direct application of lifting or balancing power
to the said lifting rail.
1 lift the bottom cone 13 by means of a vertical shaft 14, at the back of the
"frame" and operated by a handle 15 from the front of the frame, at the fore end
of the shaft 14 is a segment wheel 16 gearing with a pinion wheel 17 in which is
a crank pin 18, the latter being received and working in. a slot 19 formed in the
lever 20, connected with the carrying bracket or arm 21 for supporting the cone 13
in position When the vertical shaft 14 is turned, its segment 16 operates the
pinion 17, and crank pin 18, turning the slotted lever 20, connected therewith,
equal to the throw of the crank pin 18 which is thus brought to a dead centre,
locking the several parts 20, 21, and the cone 13, in the raised position, a reversal
of the handle 15, places the cone 13 in the lower and the several parts in their
normal position.

page_text: In order to vary the position of the cone 13 for purpose of tightening or
slackening its driving belt, the slot 25 is formed in the arm 21, and by bolt and
nut 24, it is fixed, this arrangement admits of the alteration of the position of line
without interfering with the raising and lowering motion above 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 parts 1, 2, 8, 10, 11 in combination and for purpose herein fully
described.
2. The shaft 14, quadrant, and pinion, pin 18, and slotted lever 20, in combina-
tion and as described, for purpose, and as illustrated by Figs. 3 and 4 of the
drawings annexed.
