Abstract: 2513. Weinbrenner, J. Feb. 2. No Patent granted (Sealing tee not paid) Heckling - machines; feeding and transferring flax &c. - A spanner head 31 for unscrewing the nuts 49 of the flax-holders 4 is actuated by a screwed spindle 18 carrying a nut and bevel-wheel 17 journaled in the frame, and a pinion 28 keyed thereto, the wheel 17 being actuated by bevel-wheels from the shaft 14, and the pinion 28 by bevel - wheels and pinion 26 from the shaft 22. A shaft 10, driven by gearing from the driving-shaft of the heckling-machine, carries bevel-wheels 11, 12 and 19, 20, each having teeth around one-quarter of its circumference, the wheels 11, 12 gearing with a wheel 13 on the shaft 14, and the wheels 19, 20 gearing with a wheel 21 on the shaft 22. The spanner head consists of a sleeve 32 attached within a casing 38 by. screws 62, a spring 35 abutting between a boss 34 on a transverse plate 33 and a boss 30 on the end 29 of the spindle 18. When a holder 4 stops in front of the spanner head 31, the teeth of the wheel 11 begin to mesh with those of the wheel 13, the nut on the wheel 17 is rotated, and the spindle 18 is moved towards the nut 49 but does not rotate on account of the engagement of the pinions 26, 28. If the socket 32 and nut 49 are not in position to engage, the spindle will still advance and the spring 35 will be compressed. Next the teeth of wheel 19 engage those on the wheel 21, and the pinions 28 and spindle 18 are rotated, the head 31 being driven by frictional contact between the spring 35 and the abutment 29 on the spindle 18. If the sleeve 32 is not already in engagement with the nut 49, it will spring into engagement therewith and the nut will be loosened. The teeth of the wheel 12 then engage the wheel 13, the nut 17 is rotated in the opposite direction, and the spindle 18 and the head 31 are withdrawn from the nut 49, and finally the teeth of the wheel 20 engage the wheel 21 and the spindle 18 is rotated back to its original position. The flax released from the holder 4 is received between rollers 36, 37, which are separated for that purpose by cams 41 on a driven shaft 40, which abut against projections 42 on rods 43 carrying the bearings of the roller 37, the roller 37 being normally pressed towards the roller 36 by springs 44 connected to the projections 42. The roller 36 is rotated by belt drives from shafts 10, 40, and the flax received between and withdrawn by the rollers falls into a boat-shaped receptacle 45 connected by a cord 80 to an eccentric 48 on the shaft 10. A projection 59 on the receptacle 45 rides under a bar 60, which is curved upwards at the end position of the boat so as to allow the boat to tilt downwards and empty its contents into a receiver 47, mounted on a shaft 46 rotated at intervals by means of gearing toothed over only a quarter of its circumference so that the successive tufts of flax lie at right-angles to one another. The rotation of the eccentric causes the receptacle 45 to move against the action of a spring, and, after tilting, the eccentric rights the receptacle, and the cord 80 being slackened the receptacle is returned to its original position under the action of the spring. Another method of reciprocating the receptacle 45 is shown in Fig. 7, in which bevel - wheels 48<a>, 49 on the shaft 10, each toothed around one-half of its circumference, gear with bevelwheel 50, 51 on a shaft 52 geared to a shaft 55 which drives a screwed shaft 56. The shaft 56, which engages with a nut 57 on the receptacle, is thus alternately rotated in opposite directions and so reciprocates the receptacle.
