Abstract: 19,300. Longworth, W., and Stewart, W. J. Aug. 28. Heckling-machines.-Relates to the transferring- devices of heckling-machines two of which are arranged side by side, and in which the holders are automatically clamped and unclamped and transferred from a main channel to a cross channel, and vice versa, by turntables such as are described in Specifications No. 17,437, A.D. 1899, and No. 16,010, A.D. 1901, and consists chiefly in pivotally mounting the turntables on a stationary part of the framework instead of upon the ends of the rising and falling main channels. The turntable C, Figs. 2 and 4, is mounted on a spindle c supported in bearings c<1> in a bracket c<2> which is rotatably mounted on a stud c<3> carried by a part of the framework B. The turntable receives a holder a<1> from the rising and falling main channel a, which then rises and swings the turntable through a quadrant by means of a connecting-link D, lever d, and bevel-gearing d', so that it comes opposite to the cross channel. By means of a bevel-wheel c<6> keyed to the fixed stud c<3> and a bevelwheel c<5> on the turntable spindle c, a second quadrantal movement is given to the turntable, so that when it comes opposite to the cross channel it has turned the holder from a vertical plane into an horizontal plane. In machines such as are described in Specification No. 17,437, A.D. 1899, this secondary movement is not required and the turntable is bolted to the . bracket c<2>. A safety-clutch device is provided between the lever d and the bevel-gearing d<2> by loosely mounting the lever upon the bevel-wheel spindle d<1>, to which it is connected by the engagement of a V-projection on the lever with a corresponding groove in a spring-pressed disk E, which engages with a key on the bevel-wheel spindle. In a modification, the link D, lever d, and bevel-gearing d<2> are replaced by a bridle-rod connected to the main channel and actuating the turntable bracket by means of a crank on the bracket. In another modification the turntable H, Fig. 10, is fixed to a sector-shaped shoe h mounted to slide in a circular guide h<1> carried by a bracket h<2> pivoted on a spindle h<3>. The stud has an upwardly-projecting twisted strip k<4> engaging with a pair of rollers l carried by a bracket on the main channel a, so that as the channel rises and falls the rollers acting on the twisted strip turn it and the turntable through a quadrant and bring the turntable opposite the cross channel b. By means of a bridle-rod M attached to the shoe h, the secondary quadrantal movement is given to the turntable. A device for transferring the holders from the main channel to the cross channel is shown in Fig. 12. A lever N mounted on a fixed stud n is coupled to the ordinary catch-bar for moving the holder along the cross channel, so that the lever is operated by the catch-bar and moves the holders from the turntable into the cross channel. The lever N also controls another lever n<1> by means of a roller device n<5>, the lever n<1> having a spring catch n adapted to move the holders a' out of the main channel a into the turntable. A device for transferring the holders from the turntable to the main channel has a bell-crank lever o, Fig. 14, pivoted in a fixed bracket o<2> actuated by the catch-bar lever P and adapted to engage with a snug a<5> on the holder a<4>.
