Abstract: 133,683. Alsatian Machine Co., (Assignees of Turnstall, H.). Oct. 7, 1918, [Convention date]. Combing-machines. - A Heilmann combing- machine comprises two sets of combing-mechanism driven from one shaft but capable of independent adjustment to deliver slivers composed of different staples. The laps are supported upon positively-driven rolls 4, 5, Fig. 3. The rollers 4 are actuated by a ratchet device operated by a shaft 13 rocked by an arm 12, Fig. 2<a>, and an adjustable crank-pin 10 on a disk 9 on a shaft 8 driven from the main shaft 1. A plate 14 is fixed on the shaft 13 and carries screws 15 bearing against the edges of projections on the arm 12 which hangs loose on the shaft. The rollers 5 are geared to the rollers 4. The nipper mechanism is carried by a frame hung on a shaft 29, Fig. 7. The lower jaw 27 is carried by a frame 32 adjusted by a screw 34. The upper jaw 40 is carried by arms 39 pivoted to a shaft 38, and is raised by a bowl on an arm on the shaft 38 running on the inclined surface of a lug on the machine frame. The jaw 40 is depressed by bowls 47, Fig. 3, on spring-controlled arms 43 carried by a frame 45 hung on the shafts 29. The nipper frames are oscillated by an arm 36 adjustably mounted on the rock-shaft 13 carrying a bowl 37 which engages alternately with the two nipper frames. These frames are connected by a spring 323, and the movement of the frames is adjusted by screws 321 carried by the frames engaging at the rearward end of the swing movement with a stop 642 on the machine frame. The sliver is led from the lap 6, over a guide-plate 26 hung on the shaft 29, and under a feed-roller 72 pressed against the lower jaw 27 by a spring 76. The roller 72 is rotated step by step by a ratchet 81 and pawl 82 attached to the machine frame. The roller is capable of adjustment along the lower jaw 27. The top comb 48 is adjustably mounted on arms 50 having an horizontal movement and carrying extensions 54 which mav have plates secured thereto with inclined surfaces adapted to bear on vertically adjustable rollers 57. The arms 50 are rocked bv bowls 52 on arm 53 on a rock-shaft 103 operated from the shaft 8. The comb cylinders 62 and brushes 67 are enclosed in a casing 64 and are driven by gearing from pinions 3, 69 respectively on the main shaft 1 The detaching and piecing rollers 83 - - 86, Fig. 12, are arranged to pass the combed sliver through the pan 831 to the delivery rollers 112. The lower rollers 83, 84 are driven by gears 89, 90, 891 from a gear 92 on a shaft 921 forming part of a ratchet clutch mechanism. The roller 86 is pressed on to the roller 84 by a spring 94 carried by an arm 97, and is given a rolling motion over the roller 84 by being carried in a frame 101 hung on the shaft of the roller 84 and operated from the rockshaft 103. The roller 85 is carried in bearings in a frame plate A41 and is pressed against the roller 83 by springs 100. The clutch mechanism which imparts the necessary forward and backward rotation to the rollers 83, 84 comprises a pair of disks 117, 118, Fig. 11, mounted on the shaft 921 carrying the gear 92, and fastened together by pins 119. The disks are oscillated by a link 115, Fig. 2a, secured at one end to a gear 114 driven from a gear 65 on the combing- cylinder shaft 63, and at the other end to one of the pins 119. The gear 92 is keyed to a sleeve 121 on the shaft, and this also carries two ratchetwheels 122, 123 with teeth pointing in opposite directions. The ratchet 123 is guarded by a disk 124 part of which is cut away to expose the ratchet. The disk 117 is loose on the sleeve 121, and the disk 118 is loose on the hub of the disk 124. The pawls 126, 127 are carried by the disks 117, 118, and the disk 124 ensures that movement in one direction is greater than movement in the opposite direction. The amount of retraction of the sliver is varied by adjusting the position of the disk 124 on the shaft 921 to delay or advance the time of engagement of the pawl 127 with the ratchet 123. The dust &c. generated by the brushes 66 is drawn away through a rotary perforated cylinder 129, Fig. 3, on a shaft 130 rotated intermittingly by a ratchet arrangement operated from the rock-shaft 13. Inside the cylinder 129 is an imperforate cylinder 129<b> with an opening 129<c>. The dust &c. is drawn away by a fan. The upper detaching-rollers 85, 86 are cleared by a reciprocating member 110, Fig. 7, operated from the oscillating lever 50.
