EDMUND EDWARDS, of the firm of Edwards and Co:-, Patent Agents and
Engineers, of 40, Southampton Buildings, Chancery Lane, in the County of
Middlesex "IMPROVEMENTS IN FEEDING APPARATUS FOR CARDING ENGINES
AND OTHER PREPARATORY SPINNING MACHINERY" [a communication to him from
abroad by A. Crémer-Pirnay. et Cie, of Hodimont-Verviers, Belgium]
This invention relates to feeding apparatus for carding engines used for carding
fibrous substances, and especially to improvements on the apparatus for which
Jean Thomas Lemaire obtained Her Majesty's Letters Patent dated October 4th
.1879 and numbered 4001.
The present invention consists of suitable framework preferably of metal, across
the lower part of which is arranged a transverse shaft revolving in bearings and
Bet in motion at the required velocity by means of toothed wheels. This shaft
transmits its rotary motion by means of bevilled toothed wheels to a more or less
vertical shaft the upper end of which is provided with an endless screw by means
of which a second transverse shaft at or about the centre of the height of the
machine is made to revolve, and upon this shaft is keyed a cylinder the circum-
ference of which is provided with a sufficient number of hooks or teeth, shaped
somewhat like cow-horns.
These hooks as they revolve catch the fibrous material which is to be treated,
and which is supplied below the teeth by an endless travelling band or apron
"

page_text: whence the hooks carry it round to a moveable regulating comb arranged across
the apparatus parallel with the cylinder, and made to move in an elliptic path so
that its teeth lay the fibres upon the hooks parallel with each other.
A second moveable comb is also arranged above and parallel with the first, and
also travels in an elliptic path so as to remove the surplus wool from the hook
cylinder and also to clear the first comb, and so prevent the felting of the fibre.
The elliptic movement of this second comb is produced as follows:-The
revolution of the driving shaft first described operates by means of a crank or
excentric and connecting rod a horizontal lever turning upon a transverse shaft at
the upper part of the machine, the outer end of which lever is jointed to the
upper end of a suspended link or lever to the lower end of which is attached the
comb which has therefore a vertical reciprocating movement communicated to it.
At the same time a horizontal movement is communicated to the comb by a
horizontal connecting rod jointed to the link and having its other end jointed to a
lever upon a transverse shaft to which an oscillating movement is imparted by
means of a lever adjustable in a slot upon a plate carried by the shaft, the lever
having jointed to it a connecting rod the lower end of. which is driven by an
excentric or crank upon a lower shaft revolving in bearings parallel to the driving
shaft first described.
The first comb is attached to a regulating plate which is made to travel in an
elliptic path as follows: -
A third shaft is arranged at the lower part of the machine parallel to and between
those already described, and is connected to them by toothed wheels, of equal size
so that all revolve together. Upon the third shaft a crank or excentric operates a
connecting rod the upper end of which is jointed to a lever adjustable in a slot
upon a plate fixed upon a shaft parallel to the oscillating shaft already described,
and which is made to oscillate in the same way as the latter. The upper end of
the regulating plate to which the first comb is fixed is jointed to a lever upon this
second oscillating shaft and the comb is therefore made to move to and from the
hook cylinder, whilst the lower end of the regulating plate is connected by a
connecting rod to a lever fixed upon the first oscillating shaft, so as to cause
simultaneously a more or less horizontal movement of the comb.
The fibrous material after being combed and made even by the first comb
moving as just described; is withdrawn from the hook cylinder by means of curved
teeth upon a drum or cylinder revolving parallel with the latter, which teeth
remove the wool over a suitable separator and allow it finally to drop upon a
second endless travelling band or apron which carries it to the carding Engine.
For this purpose, the curved teeth are made to project through holes in the
periphery of the drum which is made of sheet iron. The shaft of the drum has
fixed upon it a toothed wheel driven at the proper speed, by other intermediate
toothed wheels from the driving shaft of the machine. In the interior of the
drum is arranged a longitudinal angle-iron bar to which the curved projecting
teeth are rivetted, and this bar rests upon links hinged to the ends of the drum
and connected with the upper ends of forked pieces the lower forked ends of
which embrace the shaft of the drum. To these forked pièces are fitted friction
rollers running upon heart-shaped cams firmly fixed to the bearings in which the
.shaft revolves! As the drum revolves therefore the friction rollers are raised by
the cams and lift the angle-iron bar which protrudes the bent teeth sufficiently-for
them to catch the fibre from the book cylinder. The bent teeth remain protruded
in this position until the friction rollers are drawn by spiral or other springs down
the receding edge of the cams the bent teeth being at the same time withdrawn
-into the drum and dropping the. fibre upon the endless apron below as already
.described. .
(.
A strip of leather is fixed upon a light shaft and extends for the full-length of
the drum the shaft turning in bearings and having a lever upon it jointed to a rod
the other end of which is jointed to a lever, the outer end of which rests upon a

page_text: ring formed upon a wheel or plate fixed upon one of the lower parallel shafts of
the machine. This ring has a space or break into which the end of the lever
suddenly falls at the right moment, bringing the outer edge of the leather strip.
upon the point of the bent teeth just as they are re-entering the drum, and thus
facilitating the release and dropping of the fibre. An india rubber or other stop is
arranged to limit and soften the fall of the lever.

EDMUND EDWARDS, of the firm of Edwards and Co-Patent Agents and
Engineers, of 40, Southampton Buildings, Chancery Lane, in the County of,
Middlesex "IMPROVEMENTS IN FEEDING APPARATUS FOR CARDING ENGINES AND
OTHER PREPARATORY SPINNING MACHINES (A communication to me from abroad.

This invention relates to feeding apparatus for carding engines used for carding
fibrous substances, and especially to improvements on the apparatus for which
Jean Thomas Lemaire obtained Her Majesty's Royal Letters Patent dated
October 4th 1879 and numbered 4001. In the accompanying drawing which is in
illustration of the present invention Figure 1 is a side view of the apparatus and
figure 2 a vertical section partly broken off.
Across the lower part of a suitable framework preferably of metal is arranged
a transverse shaft o revolving in bearings and set in motion at required velocity
by means of toothed wheels do, d, d'. This shaft transmits its rotary motion by
means of bevilled toothed wheels, to a more or less vertical shaft a¹ the upper end
of which is provided with an endless screw by means of which a second transverse
shaft a at or about the centre of the height of the machine is made to revolve,
and upon this shaft is keyed a cylinder i the circumference of which is provided
with a sufficient number of hooks or teeth shaped somewhat like cowhorns as
shewn on a larger scale in figure 4.
These hooks ¹ as they revolve catch the fibrous material which is to be treated
and which is supplied below the teeth by an endless travelling band or apron a³
whence the hooks carry it round to a moveable regulating comb m arranged across
the apparatus parallel with the cylinder, and made to move in an elliptic path so
that its teeth lay the fibres upon the hooks ¹ parallel with each other.
. A second moveable comb a is also arranged above and parallel with the first,
and also travels in an elliptic path so as to remove the surplus wool from the hook
cylinder and also to clean the first comb m and so prevent the felting of the fibre.
The elliptic movement of this second comb a is produced. as follows:-The

page_text: revolution of the driving shaft o first described operates by means of a crank or
excentric and connecting rod c a horizontal lever turning upon a transverse
shaft at the upper part of the machine; the end of the lever e upon the shaft fis
jointed to the upper end of a suspended link or lever g to the lower end of which
is attached the comb a which has therefore a vertical reciprocating movement
communicated to it. At the same time a horizontal movement is communicated to,
the comb a by a horizontal connecting rod h jointed to the link g and having its
other end jointed to a lever k upon a transverse shaft b to which an oscillating
movement is imparted by means of a lever u³ adjustable in a slot upon a plate
carried by the shaft b, the lever u¹ having jointed to it a connecting rod u the
lower end of which is driven by an excentric or crank upon a lower shaft p
revolving in bearings parallel to the driving shaft first described.
The first comb m is attached to a flat regulating plate m' which is made to
travel in an elliptic path as follows:-A third shaft is arranged at the lower
part of the machine parallel to and between those already described and is
connected to them by toothed wheels of equal size so that all revolve together.
Upon this third shaft u² a crank or excentric operates a connecting rod u³ the
upper end of which is jointed to a lever u adjustable in a slot upon a plate u³
fixed upon a shaft u parallel to the oscillating shaft b already described, and
which is made to oscillate in the same way as the latter.
The upper end of the regulating plate m' to which the first comb m is fixed
is jointed to a lever u upon this second oscillating shaft and the comb m is
therefore made to move to and from the hook cylinder i, whilst the lower end of
the regulating plate m! is connected by a connecting rod us to a lever k¹ fixed
upon the first oscillating shaft b, so as to cause simultaneously a more or less
horizontal movement of the comb m.
F
The fibrous material after being combed and made even by the first comb m
moving as just described, is withdrawn from the hook cylinder i by means of
curved teeth t¹ (shewn on a larger scale in figure 8) upon a drum or cylinder 8
revolving parallel with the latter, which teeth remove the wool over a suitable
separator and allow it finally to drop upon a second endless travelling band or
apron u which carries it to the carding Engine.
.
For this purpose the curved teeth are made to project through holes s¹ in the
periphery of the drums which is made of sheet iron. The shaft r of the drum 8
bas fixed upon it a toothed wheel q driven at the proper speed by others inter-
mediate toothed wheels do, d, d¹, d², d³, d from the driving shaft of the machine.
The wheels d', d², d³, q have the same number of teeth, so that the mechanism
driven by them moves isochronously. In the interior of the drum s is arranged a
longitudinal angle iron. bar t as shewn in figure 3 to which the curved projecting
teeth are rivetted, and this bar t rests upon links n', n', hinged to the ends of
the drums and connected with the upper ends of forked pieces 2 the lower
forked ends of which embrace the shaft r of the drum 8. To these forked pieces t²
are fitted friction rollers w running upon heart shaped cams v', firmly fixed to the,
bearings in which the shaft revolves. In the position shewn in the drawings as:
the drum revolves the friction rollers w are beginning to be raised by the cams v
and lift the angle iron bar t which protrudes the bent teeth t¹ sufficiently for them
to catch the fibre from the hook cylinder i. The bent teeth t remain-protruded
in this position until the friction rollers are drawn by spiral or other springs y
down the receding edge of the cams v', the bent teeth t being at the saine time:
withdrawn into the drums and dropping the fibre upon the endless apron u³
below, as already described.
A strip of leather o5 is fixed upon a light shaft 07 and extends for the full
length of the drum s and teeth t¹ the shaft o' turning in bearings and having a
lever o upon it jointed to a rod o³ the other end of which is jointed to a lever o³,
the outer end of which rests upon a ring o¹ formed upon a wheel or plate fixed
upon the lower parallel shaft p of the machine. This ring o¹ has a space or

page_text: break into which the end of the lever o² suddenly falls at the right moment,
bringing the outer edge of the leather strip of upon the points of the bent teeth t¹
just as they are re-entering the drum s and thus facilitating the release and
dropping of the fibre. An india rubber or other stop o is arranged to limit and
soften the fall of the lever o³.
Having now described the invention and the manner in which it is to be
performed, I claim :-1, the comb a arranged and operating substantially in the
manner and for the purpose described and shewn. 2. The comb m¹ arranged and
and operating substantially in the manner and for the purpose described and shewn.
3. The combination of the drum & with the moveable teeth t', arranged and
operating substantially in the manner and for the purpose described and shewn.
4. The moveable leather strip o, arranged and operating so as to assist in removing
the fibre from the teeth t¹ substantially as described and shewn. 5, The peculiar
forin of the teeth and t¹ as shewn in the drawing.
In witness whereof, I, the said Edmund Edwards have hereunto set my hand
and seal this 22nd day of November in the year of our Lord 1883.
