1, ELLIS PARKINSON of 49 Naigaum Road, Dadur, Bombay, India, Mill
Manager, do hereby declare the nature of my said invention to be as follows:-
This invention refers to improvements in or relating to carding engines and
has for its object that of providing means for setting and adjusting flexible bends
to enable the revolving flats to be set in their true position for working with the
filletting on the carding cylinder, also for grinding the wire on the said flats when
travelling on their working surfaces, which may be ground square, inclined, convex,
concave, part-convex and part-concave, part-concave and part-inclined as required
to suit long or short fibres.
This invention allows of the grinding and working surfaces being combined
in one, by which the wire on the flats and carding cylinder are ground to the
same ratio. The grinding surface and working surface can be set to the same
point to allow for contraction and expansion of the flexible bends. The latter are
provided with points for setting to position. To the card side is fitted a fixing
provided externally with a screw or thread, and the inside is turned true to receive
a setting spider mounted on the carding cylinder shaft or centre to place the
apparatus to one working centre. On the outside of the screwed or threaded
periphery of the aforesaid fixing is mounted a circular ring or bowl, with the out-
side provided with inclined screws to lift or lower arms for carrying or supporting
the revolving flats. The circular ring or bowl is provided with a spur wheel
operated by a spur wheel and other apparatus or gearing for turning the same in
either direction according to requirements. The spur wheel can be rotated by one
or more spur wheels, the latter being operated by worm and worm wheels and
other gearing from the carding engine shaft or centre. The whole can be adjusted
by inclines and screws or other means. The bottom end of each arm for carrying
or supporting the revolving flats are provided with threaded inclines to move them
up or down according to the movements of the ring or bowl on which they rest,
and are pressed thereon by springs or their equivalents.
When it is desired to increase the radius and circumference of the flexible bends it
is effected by raising the said arms, and vice-versa for a contrary effect. The arms
are provided with points to hold the flexible bends in position. To one of the arms
on each side of the carding engine is mounted a suitably formed pulley or pulleys
for the purpose of maintaining each flat in position during the operation of grinding.
The said pulley or pulleys are locked in position by levers and springs suitably
mounted. The grinding roller is mounted in adjustable or other fixings or bearings
operated by a lever or levers from cams rotated in any convenient manner from the
carding engine. Suitable gearing is provided to ensure of the revolving flats being
kept in position during the operation of grinding. A. bend of equal ratio and cir-
cumference to the flexible bends is provided on each side of the carding engine,
being carried or supported from the arms employed for supporting the revolving
flats, to guide the latter in the correct position for being operated upon. This
bend or bends is so constructed and mounted that it will expand or contract in
accordance with the flexible bends of the carding engine.
To the flexible bends on the side of the carding engine are fitted inclined slips to
put the heel in the wire of the flats to prevent them being choked with cotton
during the time of working.

Improvements in or relating to Carding Engines.
I, ELLIS PARKINSON of 49 Naigaum Road, Dadur, Bombay, India, Mill
Manager, do hereby declare the nature of my said 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 refers to improvements in or relating to carding engines and has
for its object that of providing incans for setting and adjusting flexible bends to
enable the revolving flats to be set in their true position for working with the
filletting on the carding cylinder, also for grinding the wire on the said flats when
travelling on their working surfaces, which may be ground square, inclined, convex,
concave, part-convex and part-concave, part-concave and part-inclined as required
to suit long or short fibres.
This invention allows of the grinding and working surfaces being combined
in one, by which the wire on the flats and carding cylinder are ground to the
same ratio: The grinding surface and working surface can be set to the same
point to allow for contraction and expansion of the flexible bends. The latter
are provided with points for setting to position. To the card side is fitted a
fixing provided externally with a screw or thread, and the inside is turned true
to receive a setting spider mounted on the carding cylinder shaft or centre to place
the apparatus to one working centre. On the outside of the screwed or threaded
periphery of the aforesaid fixing is mounted a circular ring or bowl; with the
outside provided with inclined screws to lift or lower arms for carrying or
supporting the revolving flats. The circular ring or bowl is provided with a spur
wheel operated by a spur wheel and other apparatus or gearing for turning the same
in either direction according to requirements: The spur wheel can be rotated by,
one or more spur wheels, the latter being operated by worm and worm wheels and
other gearing from the carding engine shaft or centre. The whole can be adjusted
by inclines and screws or other means. The bottom end of each arm for carrying
or supporting the revolving flats are provided with threaded inclines to move
them up or down according to the movements of the ring or bowl on which they
rest; and are pressed thereon by springs or their equivalents. When it is desired
to increase the radius and circumference of the flexible bends it is effected by
raising the said arms: and vice-versa for a contrary effect. The arms are provided
with points to hold the flexible bends in position. To one of the arms on each side
of the carding engine is mounted a suitably formed pulley or pulleys for the
purpose of maintaining each flat in position during the operation of grinding. The
said pulley or pulleys are locked in position by levers and springs suitably mounted:
The grinding roller is mounted in adjustable or other fixings or bearings operated
by a lever or levers from cams rotated in any convenient manner from the carding:
engine. Suitable gearing is provided to ensure of the revolving flats being kept in
position during the operation of grinding: A bend consisting of a segment of
equal diameter to the flexible bends is provided on each side of the carding engine,
being carried or supported from the arms employed for supporting the revolving
flats, to guide the latter in the correct position for being operated upon. This
bend or bends is so constructed and mounted that it. will expand or contract in:
accordance with the flexible bends of the carding.engine. To the flexible bends'
on the side of the carding engine are fitted inclined slips to prevent the wire of the
flats being choked with cotton during the time of working. The slips are also

In all the figures the same letters are employed to indicate corresponding parts.
A is the carding cylinder; B the licker-in; C the doffer; D the carding
cylinder shaft or centre; E the flexible bends; F the revolving travelling flats;
Ġ the framing, and H the grinding roller. To the card sides O of the carding
engine are fitted the fixings I, provided externally with screws or threads. The
inside of the fixings I are turned true to receive the setting spiders J mounted
on each side on the carding engine shaft or centre D, to place the apparatus to
one working centre. On the outside of the screwed or threaded periphery of each
fixing is mounted the circular ring or bowl K with the outside provided with
inclined screws to lift or lower the arms L and L' employed for carrying the bowls
or pulleys P supporting the revolving flats F, and the flexible bends E and Q.
The bottom ends of the arms L and L¹ are provided with the threaded inclines,
which sit or fit on the inclined screws on the circular rings or bowls K to move
them up or down according to the movements of the latter. The arms L and L'
are secured in position on the card sides O by the set screws g in the slots h. The
arms L and L are provided with the springs i to press them on the rings or
bowls K. When the arms L and L' are moved upwards the flexible bends E are
increased in radius and circumference, and when moved downwards they are
decreased in radius and circumference, in both cases pointing to one common centre,
that is, the centre of the carding cylinder A. The arms L and L' are provided
with the double bearing points and the single points to facilitate the alteration
of the flexible bends E and Q to the various requirements. The circular rings or
bowls Kare provided with the spur wheels or cogs M, into which gears the spur
wheels or pinions N to turn the same in either direction according to the require-
ments of the arms L and L'. The pinions N are mounted on centres R in suitable
fixings. On the centres R are mounted worm wheels S, which can be rotated at
will by means of the worm T on the upright shaft U. The latter is mounted in a
footstep on the bearings or pedestals V carrying or supporting the carding cylinder
shaft D. On the upright shaft U is mounted the bevel pinion W which is geared
into the spur wheel X on the shaft or centre D, by which the upright shaft U is
rotated when the carding engine cylinder A is rotating. The upright shaft U is
also held in the fixing Y, the latter being provided with three slots or recesses for
the purpose of maintaining the same in a central position as shown in the drawings
in Fig. 1, or for placing it on one side to put the worm T in gear with either of the
worm wheels N according to which direction it is necessary to rotate the rings or

page_text: bowls K to operate the armns L and L. The bearings or pedestals V on each side
of the carding cylinder A are provided with inclined bases which sit on inclined
blocks Z secured to the framing G by the bolts a. The bearings or pedestals V
are fitted with the adjusting screws which pass through the projections on the
blocks Z. The latter can be adjusted by the screws d mounted in the projections e
on the framing G. To the arms L' on each side of the carding engine are mounted
the pulleys or cams, of which Fig. 9 is an enlarged elevation. These pulleys or
cams are employed for the purpose of maintaining each flat F in position against
the flexible bends Q during the operation of grinding. The flexible bends are
composed of segments of equal diameter to the segments forming the flexible
bends E, and are connected to the latter by the arms L so that they will move up
and down according to the up and down movements of the flexible bends E by the
arms L and L. The flexible bends Q are of equal diameter to the flexible bends E,
and arc secured to the upper ends of the long arms L provided on each side of the
carding engine. To the flexible bends E are fixed the inclined slips to prevent
the wire of the flats F being choked with cotton before getting to their work
on the carding cylinder filletting. The latter is effected by placing the leading
side of the said slips at a point above the circumference of the Bexible bends E
and diminishing to the latter as shown in Fig. 10, thus allowing the flats to
gradually assume their correct position on the flexible bends E after passing round
the pulley P. The inclined slips d' are also employed in case grinding is performed
by a stationary rotating grinding roller, or in case cams are employed similar to
Fig. 4, by which the levers u are in a standing position. The pulleys or cams /
are mounted on the centres in the sliding blocks n in the arms L' and are locked
or held in position against the flat F being ground by the levers n' and springs o.
The grinding roller H is mounted in the adjustable fixings p mounted on the upper
ends of the arms L, being secured thereto and adjusted by the screws and nuts
in the projections on the said arms I. The screws and nuts 7 are for the
purpose of setting the fixings p to the requisite incline or angle. The fixings pare
provided with the inclined bottoms on which the bearings sit to carry the
grinding roller H.
The hearings are of such a length as to extend into the
jaws of the levers u pivoted to the arms I by the pins or centres . The outer
end of each lever u is provided with the bowl or centre which operates in
the cams, which may be of the forms shown in Figs. 4, 6, and 8 according to
the manner in which it is desired to grind the revolving flats F. The cams a
and the levers are for the purpose of moving the rolier H backwards and
forwards during the operation of grinding: The cams are mounted on shafts or
centres supported on the arms and fixings y. On the shafts or centres carrying
the cams are fixed the bevel wheels z, in which gears the bevel pinions a' on the
shafts . The latter are mounted in the fixings c', and are employed to couple
and rotate the pulleys P employed for carrying and guiding the revolving
flats Fin the correct path to and from the flexible bends Q for the purpose of
grinding.
The chief feature of this invention is that the grinding and working surfaces for
the travelling flats are combined, by which the flats are ground when in a position
similar to that when at work on the carding cylinder.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1. The general arrangements, constructions, and combinations of parts composing
the improved combined setting and grinding apparatus for carding engines, as
herein before described and as illustrated in the annexed drawings.
2. As means for producing a united or simultaneous action between the grinding
and working surfaces for the revolving flats coupling the flexible bends E and Q,
substantially as described.
3. In a carding engine for the indicated purposes the combination of the

page_text: screwed fixings I, rings or bowls K, arms L and L' coupled to the flexible
bends E and Q, with means for operating the latter up or down, substantially as
described.
4. In combination with the screwed fixings I, rings or bowls K, arms L and L',
the use of the setting spiders J mounted on the carding cylinder shaft, substantially
as described.
5. In a carding engine the combination of the cams on the sliding blocks in
the sliding arms L', the levers n', and springs o for the purpose specified, sub-
stantially as described.
6. Grinding the wire of revolving flats as shown in Figs. 5 and 7 to prevent
choking, substantially as described.
7. For grinding the wire of revolving flats as shown in Figs. 5 and 7 the com-

inclines p', and angular blocks s carrying grinding roller H, substantially as
described.
8. In a carding engine the use of the inclined blocks Z carrying the carding
cylinder shaft pedestals or bearings, and the means for adjusting the same according
to the requirements of the carding cylinder, substantially as described.
9. In combination with the flexible bends of a carding engine the use of the
slips d for the purpose specified.
