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.
