Abstract: 24,067. Barbour, T., and Suffern, W. S. Oct. 31. Heckling - machines; feeding and transferring flax &c.- In a duplex heckling- machine, the holders are carried from one machine to the other by means of an endless chain C, Figs. 1 and 2, mounted on two or more sprocket-wheels c and carrying holder carriers d formed with V-shaped beds for the reception of the head d' on the holders. The chain is given an intermittent motion, corresponding to the lifts of the channels, from a cam c<19> on a shaft c<22> through the medium of a weighted lever c<16>, connecting-rod c<15>, clutch device c<7> ... c<14>, and links c<6> connected to levers c<5> loose on the shafts c' and carrying weighted pawls c<3> actuating ratchet - wheels c<2> on the sprockets c. The holders D are slid, at the feed end of the machine, from the channel A<1> into the carriers, and at the changing-end of the machine, Fig. 2, out of the carriers into the channel B' by levers f<9> slidably pivoted at f<11> and operated through levers f<8>, shaft f<7>, arm f<8>, rod f<5>, and weighted lever f from a cam F similar to the cam c<19> but set at 90 degrees in advance of it on the shaft c<22>. The carriers at the feed end of the machine are pivoted to the chain sheet, a pivot d<2> on each carrier having an arm d<3> carrying a roller d<4> travelling in a channel d<5> shaped so that the holders are turned with their length in the direction of travel of the chain sheet. The carriers at the changing- end may be similarly pivoted, but, as shown, they are fixed transversely to the chain sheet, and the mechanism for pulling-through the flax comprises levers E, E<1> having holding-jaws e, e'. The lever E is fixed to a sleeve e<2> journaled on a shaft e<3> and carrying an arm e<5> operated through a rod e<6> from a cam e<10> on the shaft c<22> and an arm e<11> connected by a chain e<12> to a hook e<14> carrying a weight e<15>; the lever E' is fixed to an arm e<16> carrying a weight e<17> heavier than the weight e<15> and connected by a chain e<18> to the hook e<14>. The cam raises the jaw E and weight e<15>, thus allowing the weight e<17> to descend and lower the lever E' upon the flax and lever E; further upward movement of the jaw E causes the jaws to move together and pull the flax through the bolder. As the cam continues to rotate, the parts return to their original position. The holders pass over a guide G, Fig. 7, as they are transferred from the rising and falling channels to the chain sheet, and vice versa, the guide comprising a bracket pivoted at g to one arm of a weighted lever g<1>. The bracket is pivoted on the shaft c<1> and supported by an adjusting - screw g7 passing through a fixed abutment g<5> supported by an adjusting-screw g<2> which bears on the lever. An extension g<3> of the bracket and the lever g<1> are connected by chains g<4>, g<8> with the stop-rod H, and should a holder O be left partly in the channel and partly in the guide, the chanpel in its upward movement turns the guide about the pivot g and raises the chain g<4> to operate the stop motion; should a holder remain partly in the guide and partly in the chain sheet, the rotation of the chain sheet turns the lever g' about the shaft c<1> and raises the chain g<8> to operate the stop-motion. The clutch device, Fig. 8, consists of an arm c' fixed on the shaft c<8> and having a tooth c<9> actuated by a recessed arm c'‹ engaging therewith and pivoted at c<11> to an arm c<12> loose on the shaft c<8> and operated by the rod c<15>; a spring c<13>, arranged between the arm c<10> and a projection c<14> on the arm c<12>, normally holds the parts c<9>, c<10> in engagement, but should any obstruction prevent the chain sheet moving forward, the arm c<10> slips over the tooth c' and operates the stop-motion, the arm being connected by a rod h<6> with a shaft concentric with the shaft c<8> and connected by levers h<2>, h<4> and chain h<1> with the stop-rod H.
