Abstract: 7120. B÷hmer, M., and Tr³benbach, W. March 25. Combing-machines.- In a Heilmann combing- machine adapted to treat two laps simultaneously, the laps are arranged at the bottom of the machine and are conveyed upwards and inwards to two separate piecing- mechanisms, which co-operate with a pair of rollers located above the machine to combine the two slivers so that the ends of the tufts of one sliver are laid upon the middles of the tufts of the other sliver. By this means, in piecing each separate sliver a short return only of the tufts is required. The combing- cylinders 2, Fig. 7, carry two toothed segments 3 and two leather detaching-segments 4, the latter being made longer than usual. The waste &c. is removed by brushes 5, doffers 6, and oscillating combs 7. The nippers comprise upper jaws 13 which are secured on spindles 12 and operated by cams 39, Fig. 8, bearing on. spring-controlled arms 35 and lower jaws 14 which are pivoted on the spindle 12 and pressed upwards by a spring 33, Fig. 7, connecting arms 31. The upward movement is limited by a stop 15, which is engaged by a screw 9 on an extension 8. The top combs 19, Fig. 9, are carried bv arms 18 connected to arms 17 on rock-shafts 16, to which are keyed slotted arms 75 engaged by a pin on a bar 77 operated by a cam 80. The bars 77 are carried by arms 78 depending from the spindles 12, and the arms 78 are connected by a spring 88. The to-and-fro motion of the comb is regulated by adjusting the vertical slide 76 which carries the pin on the pushbar 77. The vertical motion of the comb is regulated by the bowl 82 sliding on the surface 83. The laps 27 are supported upon rollers 25 and are led between rollers 21, 22 over guide tables 86 to the feed rollers 84, 85. Covers 28, 29 hinged at 30 enclose the inner side of the laps. The detaching-rollers 41, Fig. 8, which co-operate with the combing-cylinder segments are raised during the passage of the comb segments by arms 108 carried by a rock-shaft 43 operated by an arm 44 and cam 46. These rollers are weighted through arms 48 having terminal hooks 47. The lower piecing-rollers 40, Fig. 10, are driven from a gear-wheel 90 through a train of gearing 100, 101, 102, and 103. The wheel 90 is loose on the shaft 1 and is driven through a gear 91 carried at the end of a lever 92 centred on the shaft 1 and oscillated by an arm 93 sliding upon a block 94 mounted upon the other shaft 1, and operated by a cam 96. The gear 91 is driven by a gear 89 on the shaft 1, which is driven from the main shaft 34 by gearing 97, 98. The slow return movement is given to the piecing-roller when the lever 91 is swinging in the same, direction as the direction of motion of the gear 89. The upper piecing-rollers 42 are driven from the lower rollers 40. The pieced slivers are passed along troughs 52, Fig. 7, to a pair of rollers 51 driven from the gear 102. These rollers are placed to one side of the machine in the position requisite to unite the two slivers as above described. The cleaning-brushes 5 are driven from the main shaft 34, Fig. 8, through gearing 57, 58, 59, 60, while the doffing-cylinders 6 are driven from one of the comb-cylinder shafts. The doffing-combs 7 are operated by an eccentric on the shaft 34. The combing- cylinder shafts 1 are driven as above described from the shaft 34.
