PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
We, ALFRED WILLIAM LOWE, of the Firm of W. S. Lowe, Cotton Spinners
and Manufacturers, HENRY HORRIDGE BULLOUGH, Manager, and SAMUEL
LEES, Carder, all of Torr Vale Mills, New Mills, in the County of Chester, do
hereby declare the nature of this invention to be as follows:-
This invention is designed to prevent carding through and to stop the delivery
or doffer cylinder when the feed ceases.
It consists essentially in applying a roller finger or other presser to rest upon the
lap as it passes to the feed rollers and connecting the same with the driving
mechanism of the doffer cylinder so that when the lap is absent the doffer cylinder
will be thrown out of gear and stopped.
In carrying out the invention a pivoted weighted or balanced lever is supported
on the frame end or other convenient place one end of which extends over the feed
plate. To this lever is suspended or connected a roller finger presser or the like
which rests upon the lap as it is drawn into the machine by the feed rollers. In
the feed plate or dish is cut a hole or slot into which the roller or presser can fall
when not supported by the lap. The pivoted lever and presser or roller are
preferably connected to the doffer driving mechanism by an upright rod and a
longitudinal horizontal rod so that when the one is raised the other is released and
drawn back by a spring thereby causing the doffer lever to drop and throwing the
driving wheels out of gear.
Any other suitable connection may be made to release the doffer lever and
throw the wheels out of gear, or the pivoted lever may if found desirable be
connected with a strap fork which it would move to throw the doffer driving strap
onto a loose pulley such being provided for the purpose.

Improvements in Carding Engines.
We, ALFRED WILLIAM LOWE, of the Firm of W. S. Lowe, Cotton Spinners
and Manufacturers, HENRY HORRIDGE BULLOUGH, Manager, and SAMUEL
LEES, Carder, all of Torr Vale Mills, New Mills, in the County of Chester, 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 is designed to prevent carding through and to stop the delivery
or doffer cylinder when the feed ceases

page_text: It consists essentially in applying a roller finger or other presser to rest upon the
lap as it passes to the feed rollers and connecting the same with the driving
mechanism of the doffer cylinder so that when the lap is absent the doffer cylinder
will be thrown out of gear and stopped.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Side elevation of carding engine.
Fig. 2. End elevation of improved apparatus.
Fig. 3. Side elevation of strap fork connection.
Above the frame A we pivot a weighted or balanced lever B the end 6 of which
extends over the feed plate. To the end b is suspended a roller C which rests
upon the lap of cotton D as it is drawn into the machine by the feed rollers E.
Instead of a roller a finger, presser or other device may be employed to rest upon
the lap.
The feed plate F is shown flat but if desired it may be indented or provided with
a hole or slot into which the roller or presser can fall when not supported by
the lap.,
The pivoted lever B which carries the roller or presser C is connected to the
doffer driving mechanism to stop the doffer cylinder when the lever falls through
the absence of feed to the card.
On the outer end of the lever B is an upright or vertical connecting rod G which
is raised when the weighted end falls. This then releases a pivoted lever H which
has been held upright by the rod G and against which the finger k on the horizontal
rod K bears. At the other end of the horizontal rod K is a lever M which engages
with the strap fork m and which is pulled over by a spring N attached to the fixed
bracket n in which the strap fork slides. The lever M rests or presses against a
stud or projection on the end of the strap fork bar or carrier. When the weighted
lever B moves and the upright rod G is raised the pivoted lever H falls forward
and releases the finger k and lever M, causing the strap fork m of the pulleys L by
which the doffer cylinder is driven to be drawn over and throw the strap from the
fast to the loose pulley.
In a modification the upright rod G is connected to a horizontal rod so that when
the first is raised by the falling of the roller or presser the other is released and
drawn back by a spring thereby causing the doffer lever to drop and throwing the
driving wheels out of gear.
Any other suitable connection may be made to release the doffer lever and throw
the wheels out of gear, or to move the strap fork and throw the doffer driving strap
on to a loose pulley such being provided for the purpose.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
'
1. The improvements in carding engines by which carding through is prevented
and the delivery or doffer cylinder stopped when the feed ceases.
2. In a carding engine the combination with feed roller and feed plate of a roller
or presser resting upon the lap which is depressed or falls when the feed ceases
thereby operating a connecting rod or lever and throwing the driving mechanism
of the doffer or delivery cylinder out of gear substantially as described and shown.
