Title: Circular cutter shears for thick plates

Filed: 1969-11-27
Abstract: 1286137 Shearing MOELLER & NEUMANN GmbH 27 Nov 1969 [9 Dec 1968] 58012/69 Heading B3W Disc cutters for thick plates have at least one cutter, the larger cutter if they are of different diameters, in the form of a cutter ring, and a segment-shaped bearing which supports the cutter ring at its inner periphery and guides it laterally. As shown, a cutter disc 1 co-operates with a ring 3 supporting cutter elements 4 and supported on a stationary segment-shaped bearing 6. A plate 7 fixed to the bearing 6 and having a flange 7a engaging in a recess in the ring 3 guides the ring laterally. The ring is driven by engagement of a pinion 10, mounted in the bearing 6 on a line connecting the centres of the two cutters, with an internal toothed track 11. Low friction means such as roller bearings are provided on the upper and lateral surfaces of the bearing 6 which may, as shown, be integral with a bearing 6a for the disc 1. When two circular shears are disposed opposite each other, e.g. for trimming opposed edges of a plate, both shears may be mounted on a support 8, one shear being slidably mounted to accommodate different widths of plate. In one embodiment, the pinion engages an outer toothed track on the cutter ring; in another, the cutter ring is attached through spokes to a driven shaft, bearings of which are resiliently pressed against stops by, e.g., springs which oppose the cutting pressure.

Title: Stop motion apparatus for knitting machines
IPC: D04B35/10
Filed: 1971-12-16
Abstract: 1338453 Knitting-machines N LEVIN and T A OLIVER Jnr 16 Dec 1971 [4 Feb 1971] 58532/71 Heading D1C A stop motion for a creel of a circular knitting machine is automatically resettable after it has responded to excessive yarn tension. The stop motion comprises a lever 30 attached to a collar 34 rotatable on a shaft 28. The running yarn passes across the bifurcated end 30a of the lever and supports a feeler 58. If the yarn slackens, the feeler contacts a stop bar 48 to initiate stoppage of the machine. The lever 30 is normally held in a horizontal position by a pivoted lever 60 urged by a spring 76 so that a notch 60a engages a pin 46 on the lever. If the yarn is tensioned excessively the lever 30 drops, the end 60b of lever 60 is urged into contact with a wire 80. This initiates stoppage of the machine, and resetting of the device after a short delay to allow the working parts to come to rest. The lever is reset by a second collar 38 which is fixed to shaft 28. On rotation of the shaft screw head 42 abuts head 36, so that the collar 34 and lever 30 are raised to a horizontal position. The shaft 28 is rotated by a chain engaging a sprocket and moved by a pneumatic cylinder. The lever 30 is latched to lever 60 by increased pneumatic pressure at the end of the cycle. It is expected that the raising of the lever will release the yarn from any condition causing it to be tensioned excessively. If the yarn is not released lever 60 remains in contact with wire 80 and the machine will not restart. The resetting mechanism is itself reset by slowly venting the pneumatic cylinder.
