Abstract: 20,065. Wilson, T. E. Sept. 23. [Cognate Application, 23,464/14.] Cleaning machinery p n e u m a t i c a l l y. - In pneumatic apparatus for automatically collecting and removing stripped waste, fibrous dust, &c. from the carding-surfaces of carding- engines, each of the surfaces is provided with a nozzle, and the nozzles are connected through valved passages to one or more filter-collectors, the exhausting action of the nozzles being intermittent and successive. A saddle-like casing E, Fig. 1, fitted over the cover D of the doffing- cylinder C and connected to-exhausting-means, has two narrow nozzles F, G arranged parallel with the axes of the cylinders A, C, the nozzle F being located in the angle between the doffer C and the main cylinder A and serving to remove intermittently the waste stripped from the flats B and the dust detached by the stripping-brush when this is applied to clean the cylinder A, while the nozzle G is situated on the opposite side of the doffer C and serves to remove intermittently the fibrous dust oollected in the doffer and also the dust detached from the doffer when the stripping-brush is applied. The side walls of the casing E are shaped so as to form passages of decreasing width and increasing depth leading from the nozzles F, G to the outlet pipe H, which fits the exhaust pipe K telescopically. The pipe K is forked, and the two branches k1, k2 lead to separate filter-oollectors. The branches k1, k2 are fitted with valves a, b, and the casing E<2> with valves c, d, which serve to cut off the nozzles G, F, respectively. The valves a, c and the valves b, d are linked together so as to open and close together, and are operated intermittently and alternately by any suitable gear driven from some slowrunning part of the machine. The casing E may be independent of the cover D, or the cover may form the underside of the casing. The cover is provided with a turned-up stiffening-edge d2, and, when the cover is integral with the casing, a series of holes g, may be provided in the cover adjacent to and parallel with the edge d2. The nozzle G may be provided with a hinged cover g2, Fig. 2, which is turned up when the stripping-brush is applied to clean the cylinder C. When the brush is applied to clean the cylinder A, a door fitted to the cover D is turned back, and the waste removed is withdrawn through the nozzle F. In the modification shown in Fig. 2, the pipe H of the casing E is connected to the filtercollector for the waste and dust, and a rotating brush M cleans the doffer C, the waste being withdrawn by the intermittent exhausting effect of the nozzle G. The waste is continuously stripped from the flats by a knife N, and falls into a trough 0, whence it is withdrawn through a nozzle P connected with a pipe Q and through a filter-collector to the exhausting-means. The nozzle F is used to collect the waste and dust removed from the cylinder A by the stripping- brush J1. Instead of a knife N, a continuously rotating brush may be used, the waste being collected from the brush by a comb situated beneath the nozzle P. When a number of carding-engines are arranged in lines, the outlet pipes H, Q, Fig. 5, of the several engines in each row are connected by valved branch pipes h2, q2 to main pipes h3, q3 leading to the filtercollectors V, W. The valves h4, q4 in the branch pipes are opened automatically and successively by a valve-gear, which may consist of an endless chain driven slowly across the ends of the rows of the machines, and provided with one or more engaging pieces which first open the valve h4 in the branch pipe h2 and then the valve q4 in the other branch pipe q2. Specification 6633/13 is referred to.
