Specification Accepted, 13th Sept., 1887.
I, SAMUEL D. KEENE of the City and County of Providence, State of Rhode
Island, U.S.A. Mechanic, 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:-
This my present invention, relates to certain novel improvements in Carding
Machines, adapted more especially for the carding of cotton or other vegetable fiber;
and consists of an attachment, combining slotted end frames, separator-bars adjustably
secured to said frames, and means for adjustably securing the attachment to the
card frame.
It also consists in the novel device for adjustably securing the separator-bars to
the curved frames, whereby each bar is adapted to be axially adjusted with relation
to the "licker-in" or roll, and independently of the other bars composing the
separator.
It further consists in providing the slotted end frames of the said attachment with
a gauge or scale, whereby the separator-bars, mounted in the frames, are adapted to
be accurately spaced, all as will be more fully hereinafter set forth and claimed.
The object of my invention being to provide carding engines with improved means
for extracting motes and other foreign matter from the staple prior to feeding it to the
main cylinder thereof.
In the accompanying sheet of drawings, illustrating the invention, Figure 1,
represents a partial vertical transverse sectional view of a cotton carding machine,
showing the separator-bars, etc., in position below the licker-in or leader roll. Fig. 2
is a detached plan view of the separator. Fig. 3 is an enlarged partial side view of
the curved end frame, showing two separator bars adjustably retained in position
therein. Fig. 4 is a transverse sectional view of the same, taken on line xx.
Fig. 5 is a plan view thereof. Fig. 6 is a detached perspective view of one of the
clamping-dogs. Fig. 7 is a similar view of one of the roughened gibs, adapted to
be used in connection with said dog. Fig. 8 is an enlarged side view, showing
the manner of joining the curved end frame to the short end frame, secured to the
card frame below the "working" or cleaner-roll, and Fig. 9 is a view similar to
Fig. 1, the working roll and short end frame, however, being omitted. The cotton
in this case passing from the feed-rolls to the leader-roll and thence direct to the
card-cylinder.
The following is a detailed description of the invention, including the manner of
its oneration

page_text: I will, however, first describe the parts of the carding machine which are common
to this class of mechanism, and as represented in the drawings. A, referring thereto
in Fig. 1, indicates the card cylinder covered with card clothing having wire teeth a
and secured to the shaft S as usual. RR designate the feed-rolls, between which
the staple is fed to the said cylinder A. E being the licker-in or leader-roll, and
J indicating the working roll, which latter delivers the staple to the card cylinder.
L designates a curved and grooved end frame secured (one at each end) by means
of screws c, to the main frame F below the working-roll J. These frames are adapted
to receive T-bars B', thus forming a separator, also as common. To the front end of
the frames L is formed the socket d into which the rear end d of the curved end
frame D (about to be described) is adapted to interlock, as shown enlarged in Fig. 8.
D D, designate curved end frames which are adjustably secured to opposite inner
sides of the card frame F by screws c. Each frame has a slotted opening c¹ formed
in its lower portion through which the screw passes. The radius for describing the
curvature of the frame being slightly greater than that for the leader-roll E. The
upper or concave side of the frames D are each provided with a series of grooves g,
to form a gauge. The lower or convex surface thereof being roughened or
corrugated, as at n¹. t, indicates a continuous groove formed in the face of the said
frame.
(See
H, Fig. 6, designates a dog or clamp having at one end an arm p' projecting at
right angles therefrom, said arm being drilled at p, to receive a journal b of the
separator-bars B. The opposite end of the dog H, is drilled and tapped to receive the
set-screw, the point of the latter engaging-when in use the metal gib s.
Figs. 3 and 4). The said gib being provided with ears s', which serve to retain it in
position longitudinally, whilst a lip m formed on the dog, serves to prevent the gib
from working out laterally. The upper surface (Fig. 7) n, of the gib is concave and
also made corrugated to conform, essentially, to the lower surface n of the frame D,
before described, and as shown in Fig. 3.
B B, indicate separator-bars, each end thereof being provided with an off-set
journal b, fitted to the hole p, of the clamp H, (See Fig. 4). Said bars may be
T-shaped or angular in cross-section as desired.
It is obvious that the separator-bars may be adjustably retained in position, both
axially and circumferentially, in the curved end frames D, by means of the clamps H,
gibs 8, and screws, just described.
The operation is as follows ;-
The curved frames D D, are first secured to opposite sides of the card frame F, by
the screws c, and interlocking with the short supplemental frames L' if desired, as
shown in Fig. 1. I prefer, in ordinary work and using medium staple, to set the
forward end of the frames D, so that the upper edge of the first bar B, just clears
the leader-roll E, while the rear end of said frames are adjusted so as to carry the
adjacent bars about three-quarters of an inch from the said roll.
It is obvious, however, that the adjustment of the frames D, should be made with
reference both to the kind of staple or fiber, and the quality being used. The
separator-bars B, should for like reasons be adjusted to the varying conditions of
staple and grade.
For the lower grades of cotton, containing a large amount of notes, seeds, and
other impurities, the bars should be set at quite an angle, so as to forin comparatively
large openings between them. Such axial adjustment being readily accomplished
by loosening the screws I, then turning said bars to the desired position and
retightening the screws. The journal b, then bearing against the lower surface of
the groove t, of the frames D, as shown in Figs. 3 and 4. To facilitate and
ensure the true alignment of the bars, I have introduced the gauge 9, as indicated
in Fig. 2, 5, and 8.
In Fig. 9 all the bars B, are-represented as being substantially equi-distant from
the leader-roll.
Now, upon rapidly revolving the rolls E, J, and the main cylinder A, and feeding,
say, cotton staple =, between the feed-rolls R, the staple is first taken up by the

page_text: leader-roll E, from which it is carried to and taken off by the working-roll J, which
in turn delivers it to the card cylinder, as usual. While the staple is thus being
rapidly conveyed by the roll, E, from the feed-rolls to the working-roll J, the bars B,
serve to intercept and separate the impurities, thrown off by centrifugal force, from
the cotton and conduct the same through the openings i, to the floor or a suitable
receptacle placed beneath.
The dogs H, together with the bars B, may be readily removed from the frames D,
when desired. The latter also may be quickly detached from the frames F and L
by first removing the screws c.
I am aware that attachments, provided with bars for separating impurities from
cotton, etc. have been applied to carding engines prior to my present invention, there-
fore I do not broadly claim such apparatus.
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 :-

feed rolls to the carding cylinder, dogs or clamps, having said bars journaled
therein, and means for retaining the bars in position after adjustment, the whole
constructed and arranged substantially as described and for the purpose hereinbefore
set forth.
Second. The combination, with the curved end frames D, having a gauge or
graduate formed in its concave face, and means for securing said frames to a

Fifth. The combination, with the curved frame L, having a socket d formed
therein, and means for securing the frame to the carding machine, of the curved
frame D, having an end, d, thereof adapted to rest in said socket, and means for

and for the purpose herein before set forth.
Sixth. The combination, with the curved end frames D, having a concentric groove t,
formed therein, of the dog H, the separator-bar B, journaled therein, adapted to be
loosely fitted into the groove t, and a clamping screw and gib for adjustably securing
the dog and separator-bar in position upon the end frame, substantially as shown and
hereinbefore set forth.
