Improvements in Apparatus for Stripping the Flats of Carding
Engines.
I, JAMES WILLIAMS, of Springfield Works, Springfield Lane, Salford, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to
be as follows:-
This invention relates to apparatus for stripping the waste from revolving flats
and is designed more particularly for stripping broad flats which have been ground
hollow on the face though it may also be applied to any other form of flat.
It consists essentially in adjusting the stripping comb to the contour of the flat
by means of a cam rotating with the flats and the surface of which is shaped to
correspond with the face of the flat against which the bracket carrying the
bearings of the comb is caused to rest.
In carrying out the invention we place on either end of the shaft by which the
flats are caused to revolve a cam with a number of spaces or parts of its periphery
shaped to correspond to the face of the flat.
The stripping comb is pivoted or fulcrummed in any convenient way either outside
or inside the periphery of the flats being mounted in a suitable bracket or bearing
to allow for the desired amount of oscillation.
The brackets carrying the bearings for the comb shaft are movable being
capable of being slid to and fro or oscillated each about a centre upon which it is

with an adjusting screw or other projecting part which engages with or bears
against the periphery of the cam so that as the latter rotates the comb is caused to
move. The brackets are held in position against the cam by springs or
weights.
The comb has imparted to it an oscillating or rocking movement in its bearings
by means of a crank or crank pin or cam or other device operated by any rotating
part of the card.

and ascertained in and by the following statement:―
This invention relates to improvements in apparatus for stripping the waste
from the revolving flats of carding engines.
It consists essentially in mounting the oscillating bar of the stripping comb in
brackets capable of moving to and from the flats, and resting upon a fixed arm or
bracket in conjunction with a revolving cam or other device provided with surfaces
parallel with the face of the flat wires, when the flats are in position to be stripped.
It will be fully described with reference to the accompanying drawings in which
sufficient of a carding engine is shown to illustrate the invention.

Referring to Figs. 1 to 4 the disc or pulley A over which the flats revolve, is
mounted upon the shaft a, and rotated in the usual manner. The disc may be of
any ordinary construction, or it may be a plain disc with a second disc A¹, indented
at a¹ to engage with the pivots d, on the ends of the flats B and cause the flats to
travel.
The comb bar F of the stripping comb D is mounted at either end in bearings
in sliding blocks C mounted on slides e on fixed or stationary arms or brackets E.
The blocks C are capable of moving or sliding to and fro on the slide of the
arm E, and are drawn towards the flats by the spiral spring e' or other suitable
spring or weight. Or the arm E may be inclined, and the block C move towards
the flats of their own gravity.
On either end of the shaft a is placed a cam or disc L, with a number of
surfaces H shaped to correspond to the face of the wires of the flat, either flat or
curved as desired. And in addition to the surfaces H I preferably form a number
of indents h to correspond with the spaces between the flats.
To each of the blocks C in which the oscillating comb bar F is journalled, is
affixed an adjustable device G, such as a screw or bracket, which bears against the
surfaces H and indents h around the periphery of the cam or disc L.
As the flats B travel along and each successively comes into position to be
stripped, the cam L rotates, and the surfaces H and indents h against which the
adjusting screws or devices G bear, cause the blocks C and the stripping comb D to
approach to and recede from the surface of the flats, so that in its stroke the comb
will always approach to within the same distance of the wire. The indents h permit
the comb to enter between the flats to strip the edges thereof.
The desired oscillating movement is imparted to the comb bar F and comb D by
a crank M affixed to one end of the bar which is connected to a rotating crank or
crank pin n on a wheel or disc N by a connecting rod or link m. The disk or
pulley N is rotated by a strap and the shaft a is connected with it and rotated by
it by the worm and worm wheels n¹ n¹¹ and n¹¹¹.
Referring to Figs. 5 to 9 special surfaces are formed upon the flats parallel with
the face of the wire against which a projecting part of the sliding blocks C bears,
and the disc or pulley A by which the flats are revolved is constructed with pro-
jections between each flat upon which the projection of the bracket bears to prevent
it falling between the flats.
The disc or pulley A over which the flats B revolve is constructed with recesses a
at one side with which the rounded back or pivot B₁ of the flats engage and on the

page_text: periphery with projecting lugs or teeth a¹ which fit between each flat and raise
the periphery of the pulley between each flat nearly to the height or level of the
flats.
The comb bar F of the stripping comb D is mounted at either end in bearings c
in blocks C, as before described. To each of the blocks C in which the oscillating
comb bar is journalled, is affixed an adjustable device G such as a screw or
bracket which serves to regulate or adjust the position of the comb.
Each of the flats is provided with a surface at H at each end parallel with the
face of the wires against which the end of the screw G bears, and the space
between the flats is made up by the indented projections or teeth a¹ on the wheel
or pulley A. As the flats B travel along, and each successively comes into
position to be stripped, the screws G in the blocks C bear against the prepared
surface H on the flats, and as the flats pass on against the indented projections or
teeth a¹ of the pulley A. The height of these projections is made sufficient to
prevent the screw head jamming between the flats, and at the same time permit of
the comb D stripping the spaces between the flats.
In Figs. 8 and 9 the surface H is cut in the form of a groove through the
inclined working surface of the flat.
If it is not desired to strip the edges of the flats or the comb to enter between
them, the projections a¹ on the pulley A may be dispensed with and a stop placed
on the bracket E to prevent the screw G entering between the flats.
The desired oscillating movement is imparted to the comb bar F and comb D
by a crank M affixed to one end of the bar, which is connected to a rotating
crank or crank pin n on a wheel or disc N by a connecting rod or link m. The
disc or pulley N is rotated by a strap and the wheel or pulley A is connected with
it and rotated by it by a train of worm and worm wheels.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
