Abstract: 3421. Jennings, R. G. March 3. Clearing-apparatus.- In yarn-cleaning devices of the kind described in Specification 10,246/11 for removing impurities, such as broken seeds, fragments of leaves and stalks, dirt burrs, lumps of fibre, &c., from cotton and other yarns after they have passed through the usual mann facturing processes, the yarn is maintained in a straight line of travel, and the impurities are gripped by co-operating curved surfaces formed by a bed 5. Fig. 3, and a pair of blades 2 pressed towards the bed-plate and towards each other by springs. The blades, together with the bed-plate, form V-shaped slots in which the impurities are deflected from the line of travel of the yarn. The space between the blades 2 may be adjusted to the size of the yarn treated. by inserting distance-pieces of different thicknesses. The edge 10<1>. Fig. 4, of the bed-plate causes the impurities to project above the bed, and a deflector 26, which may consist of a separate wire. turns them either to the left or to the right, so that they slip into one or other of the V-slots. As shown in Fig. 10, the bed 5<4> may be cylindrical, and may be mounted eccentrically on the spindle 36 and continuously rotated by means of a driven pulley 37. The impurities accumulating in the slots are freed therefrom periodically by trip mechanism, one form of which comprises pins 23, Fig. 2. on a rotating shaft 20, and rocking cams 12 which lift the blades 2 of a series of cleaning-devices successively, the discharged impurities being collected by a gathering-spindle adjacent to the cleaning-devices, which spindle rotates in a packing-pan held against it by spring pressure. Apparatus may be arranged to raise the blades 2 of the first one or two cleaning-units more frequently than the others. In the attachment of the apparatus to a winding or other machine. the cleaning-units, the shaft 20, Fig. 18, and the shaft 42 of the gathering-spindle are carried by a supporting-bar l<3> attached to a bracket 52. Pulleys 59 are continuously driven, and a spring 66 presses the pulleys outwards and causes pins 65 to engage pins 65<1> on the shafts 20, 42 and rotate them. When the yarn breaks, a shifting link 56, connected to some suitable operative member of the winding-machine, is raised, the pulleys 59 are withdrawn, and the shafts 20, 42 are brought to rest and the entanglement of the broken yarn thereon avoided. In operating n number of groups of cleaning-units in a multiple winding-machine, bars 1. Fig. 21, carrying the cleaning-units are fixed to supporting-blocks 67 slotted below to slip over a main supporting- rod 68, on which they are fastened by screws 69, the groups being mounted side by side. A rock-shaft 81. operated by a cam 85 and cam arm 82, carries an arm 86 carrying a pin 87 fitting in a slot in a lever 88 pivoted to the block 67. The lever 88, pushing aside and moving past a lug 77, reciprocates the rods 78, and adjustable tripping-members 79, acting on trin arms 73, open the V-slots for the removal of impurities. The rods 78 may be attached directly to the rock-shaft 81.
