page_text: LETTERS PATENT to Joseph Dean, of Rochdale, in the County of Lancaster,
for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF CARDING
ENGINES."
Sealed the 24th November 1876, and dated the 29th May 1876.

THE CONSTRUCTION OF CARDING ENGINES."
"IMPROVEMENTS IN
This Invention relates to the construction of carding engines, and consists of an
arrangement of mechanism applied to the "coiler" and the pinion wheel lever, for
the purpose of lowering the pinion wheel out of gear when the sliver breaks or
when the can is full, the lowering of such pinion wheel causing the stoppage of the
doffer cylinder and feed rollers.
The pinion is carried by a lever in which is inserted a bolt, such bolt or stud
being hung to a projecting latch fixed to a swinging bracket hung on a horizontal
rod or shaft crossing from the "coiler" to the lever, such horizontal rod or shaft
being supported in brackets fixed to the engine side and to the "coiler." The
projecting latch on the swinging bracket is adjustable in a slot, to allow the
fever to fall or rise as much as may be necessary to suit the size of pinion wheel
employed.
On the "coiler" end of the horizontal rod or shaft is fixed a bracket penetrating
the "coiler" casing and resting upon the upper or movable half of a catch box,
which is loose upon the ordinary upright shaft of the coiler, the lower half of such
catch box being keyed or otherwise fixed on the said shaft and revolving con-
stantly with it. The two opposite faces of the catch box are provided with inclined
projections or teeth. The exterior of the loose half of the catch box is also
provided with a projecting stud or tooth. A wire connection is brought from the
upper part of the "coiler" to a balanced horizontal latch which is hung upon pivots
in a bracket. So long as the end of this balanced latch remains above the projecting
stud or tooth outside the loose part of the box the two parts of the catch box
revolve together and no effect is produced, but whenever the horizontal latch falls it
comes in the way of the projecting stud upon the upper or loose half of the catch

page_text: box and stops its revolution, but as the lower or fixed half continues to revolve the
inclined projections on the faces of the catch box cause the upper half to be raised
and lift the bracket which rests upon it, which gives a partial revolution to the
horizontal rod or shaft, and causes the projecting catch hung to the bracket on the
opposite end of the said rod to leave the stud inserted in the pinion lever, which
lever immediately falls (having been supported entirely by the catch) and lowers
the pinion wheel out of gear.
The falling of the balanced latch is caused by the breaking of the sliver in the
following manner-An ordinary trumpet guide is fixed on an arm which is fastened
to a loose rod crossing the centre of the "coiler head," and to the loose rod is
attached a fast bracket which overhangs the wire connection at the back of the
"coiler."
The tension of the unbroken sliver upon the trumpet guide keeps the end of the
bracket overhanging the wire connection from falling upon it, but immediately the
sliver breaks the bracket is allowed to fall upon the wire connection, which pushes
the balanced horizontal latch downwards into contact with the projecting stud or
tooth upon the upper half of the catch box, which immediately riscs, as above
stated, and lowers the driving pinion out of gear.
The lifting of the arm carrying the trumpet guide is also capable of being
effected by means of a bolt sliding in a bracket and resting upon the upper face of
the spur wheel in the "coiler head," and as the can becomes so full as to lift this
wheel it causes the bolt to raise the said arm, and thus to produce the same effect
as the breaking of the sliver, and throw the pinion out of gear.
In setting the mechanism in action again all that is required is to raise the pinion
wheel lever until the stud or bolt fixed in the same passes the catch upon the
hanging bracket, when the catch falls under the stud and supports the lever.
A small tumbler lever is attached to the horizontal rod, which the rising of the
catch box slips into a projecting tooth upon the horizontal balanced latch, causing
it to be held down until the sliver is pieced at the coiler, the tension of the sliver then
causes the tooth to be withdrawn, and the tumbler lever being counterbalanced
falls away and sets free the horizontal balanced lever, which then assumes its
original position, ready to act again upon the breaking of the sliver or upon the
can becoming full enough for the coiled sliver to lift the wheel at the top.

THE CONSTRUCTION OF CARDING ENGINES."
"IMPROVEMENTS IN
This Invention relates to the construction of carding engines, and consists of an
arrangement of mechanism applied to the "coiler" and the pinion wheel lever, for
the purpose of lowering the pinion wheel out of gear when the sliver breaks or
when the can is full, the lowering of such pinion wheel causing the stoppage of the
doffer cylinder and feed rollers.
Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed
or carried into practical effect, and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference, corresponding with those in the
following explanation thereof:-
Fig. 1 in the annexed Drawing is a partial vertical section; Fig. 2, a horizontal
section; Fig. 3, a plan view; Fig. 4, a sido elevation shewing the application of my
improved apparatus to the "coiler" of an ordinary carding engine.

page_text: The pinion a, a, is carried by a lever b, b, held by a catch or projection c, c, on a
swinging lever d, d, hung on a bracket e, c, and connected by a rod f, f, to a bell-crank
lever g,, supported in brackets fixed to the "coiler." The projecting latch c, c,
on the swinging lever d, d, is adjustable in a slot to allow the lever to fall or rise
as much as may be necessary to suit the size of pinion wheel a, a, employed.
The horizontal arm of the bell-crank lever g, g, rests upon the upper or moveable
half of a catch box, which is loose upon the ordinary upright shaft i, i, of the
coiler, the lower half h of such catch box being keyed or otherwise fixed on the
said shaft, and revolving constantly with it. The two opposite faces of the catch box
are provided with inclined projections or teeth h, k, see detached view, Fig. 5. The
exterior of the loose half of the catch box is also provided with a projecting stud
or tooth l, l. A wire connection m, m, is brought from the upper part of the
coiler" to a balanced horizontal latch n, n, which is hung upon pivots in a
bracket. So long as the end of this balanced latch n, n, remains above the pro-
jecting stud or tooth 1, 2, outside the loose part of the box the two parts of the
catch box h, h, revolve together, and no effect is produced; but whenever tho
horizontal latelin, n, falls it comes in the way of the projecting stud / upon the
upper or loose half of the catch box, and stops its revolution; but as the lower or
fixed half ¹ continues to revolve the inclined projections h, k, on the faces of the
catch box cause the upper half h to be raised and lift the horizantal arm of the bell-
crank lever g, g, which rests upon it, which pulls the rod f, f, and causes the pro-
jecting catch c, c, on the swinging lever d, d, to leave the pinion lever b, b, which
lever immediately falls (having been supported entirely by the latch c, c,) and lowers
the pinion wheel a, a, out of gear.
The falling of the balanced latch n, n, is caused by the breaking of the sliver in
the following manner-An ordinary trumpet guide o, o, is fixed on an arm p, p,
which is fastened to a loose rod q, q, crossing the centre of the "coiler head," and to
the loose rod is attached a fast bracket r, r, which overhangs the wire connection
m, m, at the back of the "coiler."
The tension of the unbroken sliver upon the trumpet guide o, o, keeps the end of
the bracket 1,, overhanging the wire connection m, m, from falling upon it, but
immediately the sliver breaks the bracket 7, r, is allowed to fall upon the wire
connection m, m, which pushes the balanced horizontal latch n, n, downwards into
contact with the projecting stud or tooth l, l, upon the upper half of the catch
box, which immediately rises, as above stated, and lowers the driving pinion a, a,
out of gear.
The lifting of the arm p, p, carrying the trumpet guide o, o, is also capable of
being effected by means of a bolt sliding in a bracket, and resting upon the upper
face of the spur wheel 8, s, in the "coiler head;" and as the cam becomes so full as
to lift this wheel it causes the bolt to raise the said arm, and thus to produce the
same effect as the breaking of the sliver, and throw the pinion a, a, out of
gear.
In setting the mechanism in action again all that is required is to raise the pinion
wheel lever b, b, until it passes the latch c, c, upon the hanging lever d, d, when
the latch c, c, falls under and supports the lever.
A small tumbler lever t, t, attached to the bracket which carries the bell-crank lever
7,9, and which the rising of the c latch to slip in front of a projecting bolt u, u, upon
the horizontal balanced latch n, n, causing it to be held down until the sliver is
pressed at the centre; the tension of the sliver then causes the bolt u, u, to be
withdrawn, and the tumbler lever t, t, being counterbalanced falls away, and sets free
the horizontal balanced latch n, n, which then assumes its original position ready to
act again upon the breaking of the sliver or upon the can becoming full enough for
the coiled sliver to lift the wheel at the top.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention, the general arrange-
ment and construction of the apparatus for lowering the pinion out of gear

page_text: when the sliver breaks or the can becomes full, as herein-before described and
illustrated by the Drawings annexed, or any mere modification or imitation thereof,
constructed and operating substantially in the same or a similar manner.
In witness whereof, I, the said Joseph Dean, have hereunto set my hand
and seal, this Twenty-third day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
