Abstract
756,097. Hydraulic apparatus. VIRCHAUX, P. May 20, 1954 [May 20, 1953], No. 14880/54. Class 69 (2). [Also in Group VIII] An elastic thread feeding device, for use in a circular knitting machine, comprising a roller 61 which presses the thread against a uniformly rotating disc 28, has the roller supported on an arm 54 connected to a piston rod 49 of a hydraulically operated piston and cylinder device 50, 46 which is actuated by a pump to vary the position of the roller with respect to the centre of the disc and thereby the rate of feeding the thread. Mounted parallel with the piston rod 49 is an hexagonal drum 71 each face of which carries an adjustable stop 73 which is engaged by a stop plate 58 on the rod 49 to limit its movement. By setting the stop on each face of the drum and periodically rotating the drum by means of an eccentric 85a operating a pawl through linkage, the piston is allowed to move up or down its cylinder to vary the position of the thread feeding roller. The bottom of the drum 71 carries studs 107 which engage a lever 113 to vary the position of an eccentric ring 89 of the pump which alters the action of the radially acting rotating pistons 81 and determines whether oil from a reservoir 101 is pumped above or below the piston to move it downwardly or upwardly respectively. The pump is continuously actuated by a chain drive 78 from a shaft in the machine and a relief valve operates when the plate 58 abuts a stop 73.
