The frame 2| in the present instance is rec

screeningmembers between one pair of parallel
walls Zla.‘ and Zlb so that the screens form a con
tinuous screening surface, ?lling the hollow frame
and extending continuously between the other
pair of walls 2 lo and Zld. An opening 25 is pro 30

tially at right angles. This provides a very sat
isfactory delinting effect when the screens are
in the duct while providing screens of such mesh
that they are more easily cleaned when removed
for that purpose.
'
I provide a novel arrangement of the screen
ing members within the frame 2| so as to present
a continuous zigzag effect from side to side of
the framework. This is accomplished by hav
10 ing each foraminate screening member on one
" side contacting the adjacent member at the up
stream edge and on the other side contacting
the adjacent member at the downstream edge.
Of course the last screening member on each
15 side engages the side walls He or 21d so as to
prevent free air discharge at these points.
The mounting means for the screening mem
bers comprises channel members 3i near the
bottomof the frame’ rigidly secured to the walls
20 Zia and 2Ib in position to receive the upstream
position of Fig. 3, that is to say, the drawer-like
frame could be pulled far enough through the
opening 25 so that the rear wall 2lb thereof
forms substantially a side wall for the duct I‘!
while the screens 27 and 28 are cleaned and re
placed.
It will also be obvious that the structure de
scribed in connection with my delinting device
need not necessarily be placed for horizontal re-'
moval of the frame 2| from a vertical duct but
the device might be arranged at other positions
in any machine'so that the frame 2! is movable
sideways from the duct in which it is placed.
What I claim is:
7
1. A device‘ for delinting a lint-bearing ?uid 15
stream, comprising a portable frame having pe
ripheral walls forming a‘ duct through said frame,
a series of separate foraminate members re
movably mounted in said frame between said
?ange members 32 and 33 for supporting the
walls to provide a continuous zigzag arrange 20
ment transversely of said duct, foraminate mem
ber mounting means substantially sealing the
joints between said members and said walls while
screening members in the slanting position shown
permitting removal of said members from said
meeting edges of ' two adjacent screening mem
bers. On the walls 2m and Nb are arranged
25 in Fig. 1 in such a manner that they are slidable
between the guiding ?ange members for inser
tion and removal in the frame. In the particu
lar embodiment shown the channel 3! has the
portions 32 extending upwardly and bent in the
30 special manner shown to provide angle guiding
frame, and each foraminate member on one side 25
contacting the adjacent member at the upstream
edge and on the other side contacting the ad
jacent member at the downstream edge.
'
2. A device for delinting a lint-bearing ?uid
stream, comprising a portable frame having pe 30
members extending upwardly for substantially
ripheral walls rectangularly arranged in plan
half the height of the frame 2! and the members
33 are angle members rigidly secured to the walls
2m and 2H) to engage the side portions of the
35, screening members along the upper vertical half
of the frame 2!. The members 32 lie within the
and forming duct means open at the ends and
diverging portion of the V-formation provided
between two adjacent screens while the mem
bers 33 lie upon the outside of this same V-for
mation, thus providing the best arrangement of
the guiding members in the repeating series of
V-formations while at the same time providing
Contact and‘ guiding means against opposite
faces of each of the screening members. It will
45 be noted in Figs. 1 and 2 that the guiding mem
bers 33 begin substantially where the guiding
permitting, ?uid ?ow through said frame, a se
ries of substantially plane foraminous members
removably mounted in said frame at an angle to
the general direction of ?uid ?ow through said
frame, said members being arranged to form a
substantially continuous screening surface be
tween the walls of said frame, and mounting
means for said foraminous members comprising 40
guiding ?anges secured to the inwardly facing
surfaces‘of one pair of parallel walls of said rec
tangle and extending toward the open ends of
said frame, said ?anges extending along substan
tially the entire edges of said members adjacent 45
said one pair of walls to form sealing means there,
members 32 leave off so that between them they
said ?anges being arranged to hold said members
coact to substantially seal the joint where the
screening members substantially engage the side
in a continuous series between the other pair of
parallel walls of said rectangle, and each fo
raminate member on one side contacting the ad
jacent member at the upstream edge and on the
other side contacting the adjacent member at
the downstream edge.
3. A device as in claim 2 in which said fo
raminous members are’ inclined to the vertical 55
and arranged in continuous zigzag formation, an
50 walls 2| (1 and Zlb while the channel member 3!
seals the upstream meeting edge of a pair of
adjacent screening members. Means is also pro
vided for sealing the downstream meeting edge
of adjacent screens and in the particular form
55 shown each of the screening members 2'1 has
rigidly secured to its upper edge a channel-like
member 36 which when the screens are in opera
tive position engages over the top of and em
braces an adjacent screen 28 as best illustrated
in Figs. 1 and 2. It will be obvious from the
above description that the foraminous screening
members 27 and 28 are easily removed and in
serted through the open upper side of the frame
21 when the frame is moved outside of the duct
65 H and in the form shown themembers 281 must
necessarily be inserted ?rst and removed last
because of the special arrangement of the seal
ing members 34.
While the arrangement shown permits the
complete removal of frame 2! from the duct
for the purpose of removing or cleaning the
screening members, it will be obvious from an
inspection of Fig.v 3 that the drawer-like frame
2| might be arranged to permit removal of the
75 screening members when the frame is in the
upturned channel embracing each pair of lower
meeting edges of said members, said channels
being secured to said frame, and a removable
downturned channel embracing each pair of up
per meeting edges.
4. A device for delinting a lint-bearing ?uid
stream, comprising a hollow drawer-like frame,
said frame having peripheral walls rectangularly
arranged in plan and providing duct means open 65
at the ends, a series of substantially plane fo
raminous members removably mounted in said
frame at an angle to the general direction of
?uid ?ow through said frame, said members be
ing arranged to form a substantially continuous 70
screening surface between the walls of said frame,
and mounting means for said foraminous mem
bers comprising guiding ?anges secured to the
inwardly facing surfaces of one pair of parallel
walls of said rectangle, said ?anges extending

along substantially the entire edges of said mem
‘‘ adjacent member attheupstream edge and on
the other‘side contacting the adjacent member
frame at an angle to the general direction of
?uid ?ow through said frame, said members be
ing arranged to form a substantially continuous
screening surface between the walls of said
frame, and mounting means for said foraminous
members comprising guiding ?anges secured to
the inwardly facing surfaces of one pair of par
allel walls of said rectangle, said ?anges extend
1* at the‘downstream edge, and channel members
ing along substantially the entire edges of said
' embracing, the upstream and downstream meet
- ing edges of said foraminous members in sealing
members adjacent said one pair of walls to form
sealing means, said ?anges being arranged to

bers being secured to one foraminous member
and adapted to overlap the adjacent edge of an
