IMPROVEMENTS IN MACHINES FOR PREPARING COTTON AND OTHER FIBRE
Year: 1885

page_text: We WALTER LORD and WILL LORD, both of the firm of Lord Brothers,
Canal Street Works, Todmorden, Yorkshire, Machine Makers, do hereby declare
the nature of said Invention for IMPROVEMENTS IN MACHINES FOR PREPARING
COTTON AND OTHER FIBRE, to be as follows:-
The object of our Invention is to improve the feed motion of preparing
machines.
Our invention relates to those preparing or opening machines in which one feed
roller is employed with a number of weighted pedal levers fitted on a shaft or
fulcrum near the roller, the back ends of the pedal levers are hooked and on each
one is suspended. a flat rod or pendant the lower ends of which rods are made with
taper sides or wedge shaped and pass through a long, box; between each of these
rods or pendants is ordinarily fitted a small bowl or roller loose in the box.
When the front end of a pedal is depressed by a hard lump of fibre the back
end raises its pendant the wedge shaped portion of which moves the other pendants
sideways thereby actuating levers connected to the strap fork guide lever which
moves the belt on the cones and so drives the feed roller at a slower speed.
Now, our Invention consists in balancing the strap fork guide lever or levers in
any convenient manner in order to make the motion more sensitive as the pendants
are thus free to act immediately upon the cone belt without having first to over-
come the weight of the levers.
To diminish friction we also propose to use two bowls or rollers between the
pendants in place of one as at present.

page_text: Improvements in Machines for Preparing Cotton and other
Fibre.
We WALTER LORD and WILL LORD, both of the firm of Lord Brothers,
Canal Street Works,, Todmorden, Yorkshire, Machine, Makers, do hereby declare
the nature of said Invention for IMPROVEMENTS IN MACHINES FOR PREPARING
COTTON AND OTHER FIBRE, 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 our Invention is to improve the feed motion of preparing
machines.
Our Invention relates to those preparing or opening and scutching machines in
which one feed roller is employed with a number of weighted pedal levers fitted on
a shaft or fulcrum near the roller; the back ends of the pedal levers are hooked
and on each one is suspended a flat rod or pendant the lower ends of which rods
tare made with taper sides or wedge shaped and pass through a long box; between
each of these rods or pendants is ordinarily fitted a small bowl or roller loose in
the box.
:
When the front end of a, pedal is depressed by a hard lump of fibre the back
end raises its pendant the wedge shaped portion of which moves the other pendants
sideways thereby actuating levers connected to the strap fork guide lever which
moves the belt on the cones and so drives the feed roller at a slower speed.
Now, our Invention consists in balancing the strap fork guide lever or levers in
any convenient manner in order to make the motion more sensitive, as the pendants
are thus free to act immediately upon the cone belt without having first to over-
come the weight of the levers.
To diminish friction we also propose to use two or more bowls or rollers between
the pendants in place of one as at present.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a side view and Fig. 2 a front view of part of a preparing or opening
machine of the type hereinbefore described to which our Invention is applied.
a is the frame of the machine; b the front feed roller; c the shaft on which are
fulcrumed the pedal levers d, the extremities d' of which are hooked and support
the flat rods or pendants e; the lower ends of the pendants e are taper or wedge
shaped and are free to move sideways in the box or frame f in the direction
indicated by the arrow Fig. 2. In the box f between each pair of, pendants e two
or more bowls or antifriction rollers 9 are placed, instead of a single roller between
two pendants which is the ordinary arrangement. The end pendant e has a slot e¹
in it and is connected by a lever h to a slot ¹ in a lever i which is connected to a
slot in the strap fork guide lever ; so that when the front end of a pedal d is
depressed by a hard lump of fibre-passing under the feed roller b, the back end
raises its pendant e, the wedge shape portion of which moves the other pendants e
sideways in the box f in the direction indicated by the arrow so that the end

page_text: pendant e by its connecting levers h and i actuates the strap fork guide lever j
which shifts the belt on the cones k¹ to lessen the speed at which the feed roller b
is being driven. As already stated we balance the strap fork guide lever ; in order
to make the motion more sensitive. A convenient method of balancing the motion
is to extend the end of the strap fork guide lever j and place thereon a weight
the position of which may be adjusted as required.
That part of our Invention which relates to balancing the strap fork guide lever
or levers may be used either in combination with or independently of that part
which consists in employing two or more antifriction rollers in the place of one, or
vice versa two or more antifriction rollers may be employed irrespective of a
balanced belt shifting motion.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. In a preparing or opening and scutching machine of the type hereinbefore
stated, balancing the strap fork guide lever or levers for the purposes specified.
2. The combination and arrangement of parts for balancing the belt shifting
motion, substantially in the manner and for the purposes described and as illustrated
by the Drawings annexed.
3. The use and application of two or more antifriction rollers g
as heretofore, substantially as and for the purposes herein set forth.
