210,100. Cook & Co., Manchester, Ltd., and Cook, J. W. July 18, 1922. Feeding carding-engines. - Cotton and other fibrous material is converted in a progressive and continuous manner, by a series of co-ordinated appliances, from the, compact matted condition resulting from baling into light fleecy sheets adapted to be passed direct to the feed rollers of a carding-engine, thereby dispensing with preparatory machines such as openers and scutchers. The material is fed from a bale breaker A to bins B, where it is mixed or blended by lattices B<1>, B<2>, and a spiked roller B<3>, and is then placed in hopper feeders C comprising oppositely moving lattices C<2>, C<3>, and beaters C<4>, C<5>. The product from the hopper feeders may be allowed to accumulate, and for this purpose is delivered by perforated rollers D, D' and rollers e, e<1>, E<1> E<2>, E<3>, Fig. 1, and formed into soft rolls R; or it may be delivered in its loose state through an outlet C<7>, Fig. 8. In the former case, the rolls R', R<2> are placed on a lattice f, and in the latter the material is delivered to a lattice P. From these lattices the material is fed to a pneumatic loosening-machine G of the kind described in Specification 122,342, which delivers it in light fleeces to a licker-in roller H provided with dividing plates, from which it is conveyed by trunks h<1>, h<2>, h<3> to pneumatic doubling and feeding machines J<1>, J<2>, J<3> similar to the machine G and delivered to the feed plates of carding-engines K<1>, K<2>, K<3>. The feed to the machine G is controlled by a piano-regulator comprising rollers F<2>, f<2>, Cone drum mechanism F<6>, and a differential gear. In the arrangement shown in Fig. 8, rollers Rare carried by levers r connected with links and levers r<3> controlling the. cone-belt mechanism. The shaft p of the lattice is driven from the shaft of the feed roller R', and the shaft C<9> of the hopper feeder is driven from the shaft p<1>. A flap i, Fig. 4, in the tube leading from the. licker-in H is normally maintained in the posi. tion shown in full lines by a detent M<5>, M<6> controlled by a solenoid M. If one. of the carding- engines is stopped the circuit of the solenoid is closed and the detent disengaged from a notch M<7> on a brake-band M<8>, which embraces a disc m<7> oscillated by a crank disc m<1>, whereupon the brake-band is moved by the disc until the detent engages a notch M<4>, and the flap moved into the position shown in dotted lines. The material delivered by the licker-in H is thereupon returned by the trunk h<11> to the bin until the carding-engine again starts and opens the circuit of the solenoid M. Impurities are removed from the material during its treatment through grids P beneath the beater C<5>, by the perforated rollers D, D', and through grids beneath the lickers-in C<1>, H and through the wire cages G<8> j<1>, j<2>, j<3> of the pneumatic loosening-machines. . ,
