Improvements in Mechanism for Stripping the Teeth of Revolving
Cards in Carding Engines.
I, HENRY WALSII, of 54, Brompton Street, Oldham, in the County of Lancaster,
Mechanician, do hereby declare the nature of this invention to be as follows:—
Hitherto in carding engines with revolving flats the waste fibres or strips have
been removed from the card teeth of the flats by a comb or card having an up
and down or oscillating movement imparted and reciprocating in the same path
over the surface of the said card teeth.
In practice it has been found that the said reciprocatory motion often damages
the teeth of the comb and flats by coming into contact with each other, which
contact takes place owing to the flats being pressed from the periphery of
their blocks or discs by particles of dirt and fluff entering between the ends
of the flats and the blocks or discs or owing to the flats hanging loosely from
the latter through the elongation of the chain links of the flats and as the
delicate nature of the card teeth of the flats does not permit of them being bent
backwards and forwards through the said defect, the card teeth break frequently.
The object of my invention is to provide means whereby the said defects
are entirely obviated and the cards are combed or stripped more naturally and
effectively than hitherto has been the case, namely, in the direction of the angle
of the card teeth on the flats and thereby render it easy to draw the waste
fibres from the same.
To this end I attach a comb blade to the periphery of a tube or shaft, the
ends of which I mount eccentrically in discs or on cranks having their axis
of rotation and bearing at each side of the carding engine and being suitably
rotated.
Upon the said tube or shaft I secure at one end a ring having an arm, the
free end of which is socketed in a bracket in such a manner, that the otherwise
concentric path of the comb teeth is converted into an eccentric or irregular one,
or path resembling an ellipse and the said arm being rendered adjustable on
the said comb tube or shaft, the teeth of the comb can be set to move at any
required angle relative to the card teeth.
In lieu of the said discs or cranks, the said comb may be rotated by eccentrics
engaging in the ends of the comb tube.

I, HENRY WALSIL, of 54, Brompton Street, Oldham, in the County of Lancaster,
Mechanician, 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:-
Hitherto in carding engines with revolving flats the waste fibres or strips have
been removed from the card teeth of the flats by a comb or card having an up
and a down or oscillating movement imparted and reciprocating in the same path
over the surface of the said card teeth.
In practice it has been found that the said reciprocatory motion often damages
the teeth of the comb and flats by coming into contact with each other, which
contact takes place owing to the flats being pressed from the periphery of
their blocks or discs by particles of dirt and fluff entering between the ends
of the flats and the blocks or discs or owing to the flats hanging loosely from
the latter through the elongation of the chain links of the flats and as the
delicate nature of the teeth of the flats does not permit of them being bent
backwards and forwards through the said defect, the card teeth break frequently.
The object of my invention is to provide means whereby the said defects
are entirely obviated and the cards are combed or stripped more naturally and
effectively than heretofore has been the case, namely, in the direction of the angle
of the card teeth on the flats and thereby render it very easy to draw the waste
fibres from the same.
And in order that my invention may be more fully understood I have caused
to be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1, Sheet I, is an-end view, Fig. 2 a sectional plan, Fig. 1 a diagram of
my improved card stripping motion, Figs. 3 & 4 are respectively an end view
and sectional plan of a modification of the same. Figs. 5, 6, 7 & 8, are respectively
sectional end views and plans of my improved card stripping motion adapted for
use of existing. combs.
Fig. 9, Sheet II, is an end view, Fig. 10 a plan, and Figs. 11 & 12 sectional
plans of some further modifications of my invention.
is the bracket bolted to the outer side of each bend carrying the disc b
which support the flats c. To each of the said brackets is secured a beading
formed in two parts d, e, the outer part e of which is rendered adjustable upon
the inner part. In each of the said outer parts is mounted a disc or cylindrical
body, one of which is formed with a stud 9. having secured thereto a rope
pulley by which the said discs or cylindrical bodies are jointly rotated from
any suitable moving part of the carding engine.
To the discs or cylindrical bodies f I secure eccentrically a shaft i and upon
the latter I place a tube & to which is attached the comb 7 by which the teeth
of the card flats c are stripped, the said dises or cylindrical bodies and shaft
actuating the said comb in crank fashion.
·
Upon the said tube I secure at one end a ring m having an arm n, the free
end of which is received by the socket o mounted in the bearing e so that the
otherwise concentric path of the teeth of the comb is converted into an eccentric
or irregular one, or path resembling an ellipse, see more particularly Fig. 1.
By the set screw in the ring m the comb 7 is rendered adjustable therein,
so that the teeth of the comb can be set to move at any required angle relative to
the card teeth,

page_text: According to a modification, see Figs. 3 & 4, the said crank motion or irregular
path of the comb resembling an ellipse, may be obtained by employing in each
of the bearings e an eccentric f and upon the same the tube k which carries the
comb and the ring m, n as in the former instance.
According to another modification I may dispense with the aforesaid comb
tube and employ loosely upon the shaft i two arms q, q, see Figs. 5 & 6, to the
free ends of which I secure the bar to which the comb 7 is attached as
ordinarily used whilst the ring m, n I secure to the boss of one of the arms q, q;
or again when using eccentrics f, f I may employ short tubes k, k on the same,
see Figs. 7 & 8, to which I secure the arms q, q and the ring m, n.
In lieu of the said rings, I may pivot to the bracket e a slide m rendered
adjustable thereon by the screws 2, see Figs. 9 & 10, adapted to engage the end
of the comb tube k which for this purpose is formed square, or I may secure
upon the comb tube, a collar m¹ formed with a square m³, as shown in Fig. 11,
and rendered adjustable by its screw p.
According to another modification of my invention I may employ the cranks f,f
which carry the comb tube shaft i, outside the bearing e, as shown in Fig. 12,
in lieu of in the body thereof as previously described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1st. In mechanism for stripping the teeth of revolving cards in carding engines,
a tube k having secured to its periphery a comb 7, the said tube being mounted
loosely upon cranks f rotated in suitable bearings, all substantially as set forth.
2nd. In mechanism for stripping the teeth of revolving carding engines, the
tube having secured to its periphery a comb 1, the said tube being mounted
loosely upon cranks f and its relative position rendered variable whereby the teeth
of the comb are caused to move in an eccentric or irregular path, resembling an
ellipse which may be varied at will, all substantially as set forth.
3rd. The general construction and combination of parts constituting my im-
provements operating substantially as and for the purpose set forth.
