Abstract: 10,739. Rhodes, W. May 12. Carding- engines. - Consists in the arrangement of a number of revolving carding-rollers of small diameter, travelling over the bends of the carding- engine in place of revolving flats, with means for automatically stripping and grinding these rollers. The rollers 1, Fig. 1, consist of long cylindrical shells, strengthened internally by ribs, and with the inner part of the ends accurately bored and fitted with shafts 5. The roller surface is truly turned and ground, and wooden plugs are driven into drilled holes. A strip of card clothing is helically wound on and tacked to the plugs or otherwise secared. The rollers are supported on sliding blocks 2 with prepared faces 6, 7. The faces 6 slide on the bends 4. Oil holes 12 are provided, and accumulation of fibres and dust is prevented by metal rings 10<x>, or the projections 9<x> may be made thicker. The rollers are coupled together by endless link-chains 10, the hollow centres of which are slid over the projections 9. On the shaft 5, at one end of the roller, is fixed a small gear wheel 11, and, at the other end, a similar chain-wheel 11<x>, Fig. 8. The endless chains 10 are passed round carrier pulleys suitably arranged on the bends, and a pair of star-wheels drive the chain and thus traverse the rollers over the bends in either direction, but, preferably, in the same direction as the revolution of the main cylinder. Front brackets 12, 12<x>, Figs. 6 and 8, are secured to the bends 4, and support the star-wheel shaft 31 driven by worm and wheel arrangement from the cylinder shaft. The notches 32 in the starwheel engage the upper portions of the blocks 2, and the prepared surfaces 7 are supported on the carrier pulleys 30. An eccentric 24 rotated by pulley and belt from the cylinder shaft imparts an oscillating motion to the shaft 20, supported in brackets 19, through the embracing-lever 23, to the short arm of which is attached a pawl 26, which operates the ratchet-wheel 27 and the attached chain-wheel 29. From this wheel 29, the stripping-roller 14, supported in the adjustable brackets 13, is driven by the chain 15<x>. As the rollers 1 are passing the stripping-rollers, their attached spur-wheels 11 gear with the wheel 17, which is driven by the wheel 16 on the stripping- roller shaft. A straight bar or lug 22 covered with stripping-fillet is carried by arms 21 fast on the shaft 20, and is thereby oscillated, clearing the roller 14. The rollers 1 are rotated, when in working position on the bends, by a chain 38, Figs. 8 and 12, which engages with the chain wheels 11<x> on the roller shafts, and is carried by guides 37, 37x, 39. This chain is driven through intermediate gearing from the chain-wheel 40 on the shaft 31, and the relative velocity of the chains 10, 38 is such that the rollers 1 make one revolution while traversing the bends. The carding- rollers 1 are ground by a grinding-roller 45, Fig. 14, driven from the main cylinder shaft, and adjustably mounted on brackets fixed to the bends. The rollers 1 are rotated while being ground by the spur-wheels 11 engaging in turn with an adjustable spur-wheel 49 driven through a band pulley from the shaft which drives the shaft 31. The prepared surfaces 6 are pressed against the plate 44 by the short arms of weighted levers 43 pressing against the curved portion of the blocks 2. The grinding- roller 45 may be mounted on sliding brackets and moved backward and forward while grinding. A cover or casing 52 encloses the carding-rollers on the bends, and is made of sheet iron or steel, in parts or segments, and is carried on rails supported on studs fixed to the brackets of the bends. Instead of the sliding blocks 2, revolving rollers or bowls may be used, in which case, a second pair of star-wheels is employed at the other end of the traverse, and, during grinding, the bowls roll over a perfectly flat surface grinding-plate, the weighted levers 43 being dispensed with.
