Abstract: 265,999. Naupert, O. Feb. 14, 1927. Fibrous material is placed in a hopper feeder and fed therefrom automatically through a series of devices including an opening device, a carding-engine, a sliver dividing device, a drawing and twisting arrangement, a sliver condensing device, and a drawing-head to a ring spinning frame. The whole machine is mounted in a single frame and driven from the one shaft. By putting certain sections of the device out of operation the machine may be used for winding the fleece delivered from the doffer of the carding-engine into a lap, or for twisting and doubling on the ring spinning frame. The machine may be used for spinning fine or coarse counts. Feeding openers, carding-engines, &c. - The hopper feeder A, Figs. 1 and 5, comprises a travelling, card-covered band 21, the lower roller of which is adjustable to alter the inclination of the band, a travelling band 19 at the bottom, and a rear wall 20, mounted on the axle of a roller 23 and pressed forward against the material by a counterweight 25. The roller 23 rests on the belt 19 and the rear wall 20 is thus moved forward as the material is withdrawn from the hopper by the band 21. Openers &c.-The opening device B, Figs. 1 and 6, to which the material is fed from the hopper feeder A by card covered cylinders 27, 28, 29 comprises pairs of travelling card covered bands 30, 31, 35, 36 the elements of which travel in the same direction but at different speeds. The clothing on the bands 30, 35 is in sections spaced apart at equal intervals. The material is passed from one pair to the other by a belt 32 and rollers 33, 34. The number of pairs of belts may be increased. Carding-engines; sliver-rubbing apparatus; openers, etc.; drawing-frames. - The carding- engine C, Figs. 1 and 6, comprises a taker-in 37, which transfers the material from the opening-device B, and two cylinders 38, 39, rotating in opposite directions and provided with workers 41, 44, and strippers 40, 43, round the greater part of their circumferences. Each cylinder is provided with fancies 41<a>, 45, the fleece being transferred from one cylinder to the other by a roller 42. The fleece 4 is finally delivered by a doffer 2 and comb 3 to a sliver-dividing device D, Figs. 1 and 8. The dividing belts 49, 50, which pass round the grooved rollers. 48, 47 and guide pulleys 51, 53, are kept taut by guide pulleys 52, 54 mounted in slotted guides and controlled by springs. The slivers 5 are taken off by pairs of rollers 55, 57, 56, 58 and passed through twist tubes 6 to drawing rollers 59 and thence to sliver-rubbing belts 8. The rovings 7 are delivered to rollers 61, 62, and are then passed through other twist tubes 6, Fig. 1, and rollers 61a, 62a to the drawing-heads 9 of the spinning frame E. The cylinders of the carding- engine C and of the opener &c, B are mounted on axially movable spindles 183, Fig. 25, supported in bushes 182 and engaging bushes 184 in the end plates 185 of the cylinder. Studs 186 on the bushes 184 engage bayonet grooves 187 in the spindles 183, or vice versa, and relative rotation of the cylinder and the spindles frees the spindles so that they can be withdrawn and the cylinder removed. The spindle bushes 182 are supported in brackets 188 secured to the frame so as to be adjustable in all directions. An intermediate bush 190 is held in the bracket 188 by two diametrically opposite screws, and carries screws 189, displaced through 90‹, which engage the bush 182. The card clothing 192 is secured to the cylinder by eyes 193 passing through coincident holes in the clothing and the cylinder 191 and the flange 194 of the end plate. At one end a flanged metal ring 194<a> is superposed and secured by additional eyes 195 passed through the eyes 193. In the opening &c. device, and in the hopper feeder, the carding-bands comprise card clothing secured to a backing by eyes 193, Fig. 27, which are engaged by studs 197 on the conveying rollers 196. Lap-forming apparatus.-When, it is desired to wind the fleece delivered from the doffer 2 of the carding-engine C, Fig. 1, into a lap for the manufacture of wadding a lap roller 14, Fig. 19, is mounted in open bearings 130 in brackets 13 adjustably secured to the main frame. A pressure roller 15 rests on the lap as it is wound and its spindle 134 rests against an adjustable slide 125 secured to the bracket 13. The slide 125 is set so that when the desired thickness of lap has been wound on the roller 14, the roller 15 rises over the top of the slide 125 and rolls along a hooked extension 129. The machine, which may be driven by a motor, or by a treadle mechanism or by a combination of the two, is operated from a main shaft 198, Fig. 28, through a series of hand-controlled gear boxes, whereby the speed of the driven shaft may be augmented or decreased, or the shaft may be put out of action. By these means certain sections of the machine may be put out of action as desired. The main shaft through spur gearing drives the clutch box 202, this drives a clutch box 209 controlling the hopper feed A, and by a chain 220 the opening device B. The shaft 198 also drives through a chain 224 a clutch box 227, through which the various elements of the carding-engine C are driven. A further clutch box 244 is driven from the box 227 and controls the sliver-dividing device D and the sliver-rubbing device 8. A further drive from the shaft 198 working through a clutch box 275 operates the tin rollers 281 driving the spindles of the spinning frame E. The roller head is driven from a shaft in the sliverrubbing device 8. Provision is made for the introduction of change gears at suitable places.
