ginning of the cotton with a fairly long staple,
and particularly under circumstances when the
cotton lint is damp from rain or otherwise. It
is found that the long lint upon the cotton will
be caught by the teeth of the saws and carried
upwardly against the hulling‘ribs so as’ to lie
any modern form of cotton gin. I have illustrated
the same in connection with the forward portion
of the gin in such manner as to illustrate the posi

which the cotton is fed to the machine. Toward

' ends of the ribs and thus not be injured.

with the gin saws to move the cotton from the

Instead of being made in a single piece the hull

upper ends to provide any opening therethrough
to allow the passage of cotton lint as will be de
scribed. With reference to Fig. 2 it will be noted
that I have shown the hulling ribs as being made
1. The gin saws will engage the lint of the cotton
and tend to carry it upwardly into the roll box,
the hulls being removed from the cotton as the
lint is drawn through between the hulling ribs.
Even though the lint be long and damp and
therefore tending to string about the adjacent
hulling ribs and thus be pushed up to the upper
ends of the slots, it will be seen that the lint will
be allowed to pass through the gap or opening
23 in the hulling ribs and be carried past the ribs
without breaking or tearing. The width of the
gap 23 may be varied to suit the character of
cotton being ginned. There will be little tendency
for the cotton lint to be carried .up to the upper
ends of the slots 26 by the adjacent ribs. Such
cotton lint as is carried past the gap 23 will be
moved downwardly toward the gap by rotation of
the picker roll 28. In this manner the clogging
of the cotton around the hulling ribs is entirely
eliminated.

The lower
ends of‘the plate or plates are imperforate ex
cept for elongated screw receiving openings 31
but at a point adjacent the ginning saws the
plates are slotted out to provide openings 24
through which the ginning saws 6 may pass. The
upper ends of the hulling ribs are connected with
a plate or plates 25 which are slotted upwardly
15 from the gap or opening 23 to a point spaced
somewhat above the ginning saws as shown at
26 in Fig. 2. The openings 37 in the lower rib
plates allow vertical adjustment of the lower ribs
to control the size of the gap 23. Thus, it will
20 be seen that the hulling ribs 2| are interrupted
or split between their ends and adjacent the
peripheries of the saws to provide a transversely
disposed gap 23, and that the upper section 25

through the gap and into the roll box l3. In
other words, revoluble means are so disposed
35 relative to the upper section and the gap to pre
clude the cotton locks from clogging the tops of
the huller ribs over the saws.
As will be seen in Fig. l, the break or opening
23 in the hulling ribs is at a point where the teeth
4,0 of the saws pass in their upward movement.
This will allow the passage of the lint over the
lower ends of the ribs, as shown at 21 in the draw
ing, so that the lint will not get caught at the
upper ends of the slots.

rib sections for moving the cotton lint collected
thereon toward the gap and the gin saws.
2. A cotton gin of the class described including 4.0
gin saws, hulling ribs associated with the saws,
said ribs being interrupted to provide an upper

formed opposite ?ngers or spikes 3|, which are
adapted to pass between the upper ends of the
huller ribs in rotation. As will be noted from
the drawing each hub has two opposed ?ngers
thereon and each hub has the ?ngers set at right
angles to those on the hubs adjacent thereto.
Each hub is attached to the shaft by a set screw
and is easily removable when desired. As. will be
noted, the ?ngers taper from the hub toward a

the cotton. The picker roll thus constructed is
60 rotated as shown by the arrow to move the ?n
gers downwardly along the upper ends 26 of the
slots between adjacent hulling ribs and move the
cotton down toward the gaps 23 and allow it to
be carried past the ribs by the gin saws.
The remainder of the cotton gin is of conven
tional type and as it has no feature of novelty it
need not be described in detail. The cotton may
be removed from the gin saws by a blast of air
delivered through the nozzle 32 toward the outlet

a brush gin or the like. There is a mote board

In the operation of my device the cotton will
75 be fed to the gin saws from the gin breast as pre
a roll box, gin saws associated with the roll box 50
for conducting the cotton thereto, hulling ribs
associated with the gin saws, each of said ribs
being interrupted to provide an upper section and
a lower section separated by a transversely dis
posed gap, and revoluble means extending between
the ribs of the upper section to move the cotton
collected thereon towards the gap and the gin
saws without breaking or tearing the cotton, said
gin saws arranged to conduct the cotton through
the gap and past the hulling ribs and into the roll 60
box.
4. A cotton gin of the class described including
a set of ginning ribs, gin saws extending between
the gin ribs, hulling ribs associated with the gin
saws, said hulling ribs comprising an upper sec-.

said gap and having diametrically opposed ?ngers 7-0
extending within the spaces formed between the
ribs in the upper section for moving the cotton
lint on the ribs of the upper section toward
the gap.
5. A cotton gin of the class described including.
