Abstract: 29,815. Huglo, V. Dec. 27. Heckling-machines; feeding and transferring flax etc.; holders for flax &c.-The holder comprises a bottom plate 1, Fig. 1, provided at its ends with upstanding projections 13, 13<1> having wedge-shaped holes, and an upper plate 5 provided with notches 3, 3<1> to fit the projections 13, 13', and carrying on its upper surface lock bolts 12, 12<1> to engage the holes in such projections. The bolts are provided with lugs 14, 14<1> by which they can be pushed into position and have semicylindrical extensions 11, 11<1> adapted to slide in a guide 10 in a flanged part 7. The inner surfaces of the plates 1, 5 may be fluted or corrugated, or provided with an elastic lining. The holders are tilted into an horizontal position at the end of one main channel and are traversed along a direct connecting-track to the other main channel, at the entrance to which they are tilted into a vertical position. As the holders pass along one connecting-track the locking-bolts are withdrawn and subsequently reinserted, the top plate being lifted in the interval to allow a fresh strick to be placed in the holder, while during their passage along the other connecting- track, the top plate is lifted slightly and the partly heckled strick is drawn through the holder so that the whole of the unheckled portion is exposed. The connecting-tracks 17, Fig. 2, are in the form of an arc or of two quarter-circles connected by a straight piece, and comprise parallel plates 18, 18<1> along the upper surfaces of which the holders slide. The holders are moved intermittently by dogs 62 which engage the lugs 6 on the holders during their forward movement. The dogs are hinged to plates 63 sliding in guides in the channel 17 and connected by rods 65. One of the plates 63 is connected to a chain 66 running over pulleys 67 and secured at one end to an oscillating sector 68 and at the other end to a counterweight 71. The forward movement is made under the impulse of the counterweight 71. The devices for opening and re-closing the holders comprise a slide 20 moved on a vertical frame 19 by a crank 24 and connecting-rod 25 operated from the main shaft 22. The slide carries two arms 21, 21', in each of which is mounted a sleeve 27, and a concentric rod 29. The sleeve is pressed downward by a spring 28 and carries a shoe 31, having side pieces 32 adapted on the downward movement of the slide 20 to engage the edges of the holder P<1>. The rod 29 continues to move after the sleeve 27 has been stopped and a cross-bar 33 carried by it engages the ends of bell-crank levers 34, 34<1> and moves them against the action of springs 37, 37<1> to engage the lugs 14 on the locking- bolts 12, 12<1> of the holder and to withdraw the bolts. The bell-crank levers 47, 47<1> on the other arm 21<1> of the slide 20 are arranged to press the locking-bolts back into position. The holder is opened to allow the heckled flax to be removed and a new strick to be inserted by a pair of spring jaws carried by arms mounted upon a shaft rocked by a connexion with the reciprocating slide 20. This connexion comprises a friction arrangement which slips in the event of any obstruction to the movement of the arms. The device at the other end of the machine for raising the top plate slightly and pulling through the partly heckled strick comprises a pair of jaws carried by an arm and stationary bracket. The jaws have inclined guides which engage under the flanges 8, 8<1> on the projection 7 on the top plate and raise it slightly. The pulling-through device comprises a weighted upper jaw depending from the slide 20 and lowered with it to engage a lower jaw which is supported by a frictional device adapted to give way in the event of any untoward obstruction to the movement of the device. The tilting-device at the end of the main channel from which the holders emerge comprises a lever 73, Fig. 14, carried by the rising and falling channel 72, and adapted to engage a stop 74 on the frame and to be oscillated to bring an arm 75 into engagement with the holder P<1>. The holder is thus tilted into an horizontal position on a short channel 76 carried by the channel 72. The holder is then moved into the cross channel 17. The tilting-device at the entrance to the other main channel comprises a section of V-shaped channel 77, Fig. 11, pivoted on an axis 79 carried by the rising and falling channel 72. The channel 77 is tilted as the channel rises by a weighted lever 81. The stricks of flax ready to be inserted in the holders are supported upon a stand 83, Fig. 8, carried by a float 84 having guiding- ribs 85 arranged in a cylindrical reservoir 86 containing liquid.
