We, JOHN PIGHILLS HEATON and JOHN HENRY BEAVER, of Low Mill, Keighley,
in the County of York, Spinners, EBER COCKCROFT, of the same place, Manager,
and CHRISTOPHER NIXON, also of the same place, Mechanic, do hereby declare the
nature of this invention to be as follows, that is to say:-
It relates to improvements appertaining to feeding mechanism for carding
engines and like machines used in the treatment of fibrous substances of the class
wherein weighing mechanism is employed for regulating the quantity of said
fibrous substance fed to said machines, and said invention consists in the con-
struction and arrangement of parts in combination whereby the supply of the
fibrous substances is automatically stopped on the scale-pan having received its
complement of it, and again restarted after said scale-pan has deposited its con-
tents and resumed its position for again receiving said fibrous substances, and
that without having to hold or retain any of the motor or delivery mechanism
against the full driving forces of their operating parts or in other words when any
of the feed delivery mechanism has to be arrested to allow the other parts to per-
form certain of their functions, the mechanism for transmitting such motion is,
according to this invention, entirely disengaged.
In carrying this invention into effect the scale-pan mechanism is arranged to
operate a lever or connecting rod in such a manner that as said scale-pan moves to
deposit its contents, as is well understood, it causes said rod to move into the path
of motion of a cam or wiper mounted on any suitable rotary or oscillatory shaft
or axle on the machine, on which, said rod is pressed by this cam to cause the
driving belt to move from the fast to the loose pulley on the shaft of the delivery
mechanism thus the further movements of this mechanism are effectively arrested.
In place of a fast and loose pulley being employed appropriate clutches may be
used and arranged to be entirely disengaged when the scale-pan is discharging
its contents.
To restart the delivery mechanism on the scale-pan having resumed its normal
position after it has discharged its contents, a cam wheel and lever device are
employed for bringing the driving belt or the clutch mechanism into effective
operation, the timing of the movements of this latter mechanism relatively with
the time of movement of the parts above described, being regulated to meet the
desired requirements.
By having the operations of the feed mechanism arranged to be put into action
or restarted by other devices than the weighing mechanism, the sensitiveness of

page_text: this latter is never interfered with so that the results it produces are at all times
even.

Improvements appertaining to Feeding Mechanism for Carding
Engines and like Machines used in the Treatment of Fibrous
⠀ Substances.
We, JOHN PIGHILLS HEATON and John HENRY BEAVER, of Low Mill, Keighley,
in the County of York, Spinners, EBER COCKCROFT, of the same place, Manager,
and CHRISTOPHER NIXON, also of the same place, 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, that is
to say:-
It relates to improvements appertaining to feeding méchanism for carding
engines and like machines used in the treatment of fibrous substances of the class
wherein weighing mechanism is employed for regulating the quantity of said
fibrous substances fed to said machines, and said invention consists in the con-
struction and arrangement of parts in combination whereby the supply of the
fibrous substances is automatically stopped on the scale-pan having received its
complement of it, and again restarted after said scale-pan has deposited its con-
tents and resumed its position for again receiving said fibrous substances, and
that without having to hold or retain any of the motor or delivery mechanism
against the full driving forces of their operating parts or in other words when any
of the feed delivery mechanism has to be arrested to allow the other parts to per-
form certain of their functions, the mechanism for transmitting such motion is,
according to this invention, entirely disengaged.
In order that our invention may be readily understood we have hereunto
appended sheets of drawings illustrative thereof to which by figures and letters,
reference is made in the following description.
Fig. 1 is an end elevation of the feeding mechanism of a carding engine show-
ing the application thereto of our invention.
Fig. 2 is a top view of parts shown by Fig. 1.
Fig. 3 is a sectional front elevation of parts illustrated by Figs. 1 and 2 in the
positions they assume when the machine is in effective operation.
Fig. 4 is a similar view to Fig. 3 but shows the said parts in the positions they
assume on having effected a stoppage of the feed mechanism.
In carrying our invention into effect the scale pan a (which is mounted upon
the lever b and counterbalanced by the weight b¹ in the well known manner) is
made to allow a lever or sliding rod c, which it supports by having same to pass
through the slotted rod d resting on the pin d'fixed on a part carried by the
pan a to descend as said scale-pan a descends by gravity on receiving its com-
plement of the fibrous substances which it has to feed to the machine, as is well
understood. The pin d' is mounted on a part carried by said pan so that the

page_text: rod d may rest thereon or be thereby supported and allowed to descend by gravity
when the pan a descends while when said pan a is in the position shown by Fig. 1
it (said rod) is raised to lift and hold the rod c as shown. The rod c passes loosely
through a slot or opening in the rod d which thus acts as its guide and carrier
or operator, while the outer end of said rod c is of a suitable inclined shape
(see Fig. 2) for the purpose hereinafter described. The descending of this rod c
brings it with its outer end into the path of motion of the rotary cam or
wiper e mounted on the rotary shaft e¹ which is used for other well known
purposes in the machine, on
c
which said rod is pressed by this
wiper e in the direction indicated by the arrow 2 to dislodge the spring f from a
notch in the bearings f, thus said spring f is liberated and moves carrying with
it the belt guide
to shift the driving belt g¹ from the fast pulley h on to the
loose pulley h¹, in this manner the well known feeding devices for carrying the
fibrous substances to the pan a are arrested.
In place of the fast and loose pulleys h h being used any appropriate clutch
mechanism may be employed as is well understood.
After the pan a has descended and deposited its contents in the well known
manner its counterbalancing weight braises it again into the position shown by
Fig. 1 which is its normal position while receiving the fibrous substances it has to
transfer to the other parts of the machine, on which, by the cam surface k¹ on the
wheel coming into contact with the antifriction bowl m³ on the lever m (which
is pivotted at 3 to the bearing carried by the framework S) this latter forces the
belt guide g against the resilience of the spring f, from its position shown in
Fig. 4 back into its position shown by Fig. 3 thus the belt gl is moved from the
loose pulley h¹ back on to the fast pulley so that the operations of feeding
devices are recommenced, while at the same time the outer end of the spring 7
acts upon the inclined end e² of the rod c and forces it back into its original
position shown by Figs. 1, 2 and 3.
By having the operations of the feed mechanism arranged to be put into action
or restarted by other devices than the counterbalancing mechanism, the sensitive-
ness of this latter is never interfered with so that the results it produces are at all
times even.
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 feeding mechanism of the class described, means whereby the stopping
and re-starting actions are effected substantially as herein specified.
2. The several parts forming the arresting and re-starting mechanism herein
described the same being constructed and arranged in combination substantially
as specified.
