PROVISIONAL SPECIFICATION.
Improvements in Openers and Scutchers for Cotton and other
Fibrous Materials.
We, WALTER LORD and WILL LORD, both of the Firm of Lord Brothers,
Canal Street Works, Todmorden, in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to openers and scutchers and consists of improvements in
the feed regulating apparatus commonly known as the "piano feed.'
In carrying our improvements into effect we couple each end pendant or fish tail
lever by an adjustable rod to an arrangement of toggle levers which are pivoted
on a fixed centre secured to a bracket fixed at or about mid length of the box or
frame in which the pendants are guided. The opposite centre of the toggle levers
is connected by an adjustable rod and elbow lever or other suitable connections to
the strap fork guide levers by which the strap is shifted on the cones.
In operation when one of the pedals is depressed and its pendant is raised one (or
both) of the end pendants is pressed outwards and the movement is communicated
through the rods, toggle levers and connections to the strap fork by which the
strap is shifted, the reverse movement taking place when the pendants return to
their normal positions.
Instead of coupling each end pendant to the toggle levers we may employ a
special lever at each end pivoted to the framing and fitted in the box so as to be
moved by the pendants.

Improvements in Openers and Scutchers for Cotton and other
Fibrous Materials.
We, WALTER LORD aud WILL LORD, both of the Firm of Lord Brothers,
Canal Street Works, Todmorden, in the County of York, Machine Makers, 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—
Our invention relates to openers and scutchers and consists of improvements in
the feed regulating apparatus commonly known as the "piano feed."
In carrying our improvements into effect we couple each end pendant or fish tail
lever by an adjustable rod to an arrangement of toggle levers which are pivoted on
a fixed centre secured to a bracket fixed at or about mid length of the box or
frame in which the pendants are guided. The opposite centre of the toggle levers
is connected by an adjustable rod and elbow lever or other suitable connections to
the strap fork guide levers by which the strap is shifted on the cones.
And in order that our invention may be fully understood and readily carried

page_text: into effect we will describe the accompanying three sheets of, drawings reference
being had to the figures and letters marked thereon.
Fig. 1 is a side elevation, Fig. 2 an end elevation, and Fig. 3 a plan of the piano
feed regulating motion of an opener or scutcher made according to our invention
and Fig. 4 is a view of part of Fig. 2 to illustrate a modification.
In the drawings,-a represents the frame of the machine, the feed apron, c the
feed roller, d the pedals pivoted on a shaft e, one end of each of these pedals bears
against the under side of the feed roller c and from the other end of the pedals are
suspended the fish tail levers f; the ends of these levers are tapered with the largest
end at the bottom where they pass through a box or frame g and are separated
from one another by bowls or rollers g' supported in the frame g. On the axis of
a beater cylinder h, Fig. 1, is mounted a pulley which by means of a band igives
motion to a pulley j on a shaft j; a pulley k on this shaft gives motion by a strap k
to a pulley secured upon the shaft m' of one of the pair of regulating cones m
and n the latter of which is driven by a strap m² from the cone m.

Each end fish tail lever f¹ is slotted, see Fig. 2, and in each slot is a bolt o for
securing a bracket P in any desired position to the slotted levers f¹; to these
brackets are secured rods pi which are connected at their other ends to toggle
levers pivoted on a fixed stud 91 carried in a bracket of the opposite joint of the
toggles being connected by a rod made in two parts and united by a right and
left hand nut to an elbow lever s pivoted on a stud s' fitted in a slot in a stationary
bracket; the other end of the levers is connected by a bolt to an adjustable
bar fitted to clip over one of the pair of pivoted toothed quadrant arms u
which are geared together and carry strap fork guides u' for the cone strap m².
On the shaft of the cone n is secured as usual a worm n¹ which gears into a worm
wheel c mounted loosely on the feed roller c a sliding clutch mounted on a feather
key on the feed roller gears into clutch teeth on the worm wheel for stopping and
starting the feed roller as required.
In Fig. 4 special end pendants f' pivoted to the frame a at f³ are shown instead
of the pendants f¹.
T
In operation when the cotton or other fibre passes in extra large lumps over say
one, two or more of the pedal levers d the ends of these levers with their dependent
fish tail levers fare raised and this lifting movement of the fish tail levers causes
one of the end levers for both of them to move outwards whereby the toggle
levers 9 are moved and the rod is drawn down, this movement being conveyed to
the elbow levers fulcrumed at s¹ raises its other end and the bar which clips one
of the toothed quadrant arms and so moves both of the quadrant arms and the two
strap forks u' the latter moving the strap m³ upward thus reducing the speed of the
driven cone n and by the worm n' and worm wheel c¹ giving a slower speed to the
feed roller c and checking the supply of fibre to the machine until the lumps of
fibre have passed beyond the feed roller when the parts regain their normal
positions.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In an opening or scutching machine the use and application of an arrange-
ment of toggle jointed levers in combination with the pendant or fish tail levers and
connections to the cone strap forks as hereiu set forth.
2. In combination, the pendant or fish tail levers, the connecting rods, and
arrangement of toggle jointed levers, the adjustable connecting rod and the elbow
lever which actuates the strap forks as herein set forth.
