Title: Improvements in and relating to a method of and apparatus for widening stocking blanks
IPC: D04B9/46
Filed: 1949-06-27
Abstract: 743,971. Knitting. LEWIS, H. N. Sept. 25, 1950 [June 27, 1949], No. 16991/49. Class 74 (2). In forming locked selvedge loops in the widened courses of the heel bulges of a, singleunit, full-fashioned stocking blank, the main thread H and at least one selvedge-reinforcing thread J are laid, in each widened course, in front of two or more outer added needles at an edge of the fabric to be widened, whilst the needles are in the raised position and the traverse of the reciprocating carrrier of each of the selvedge-reinforcing threads is limited to not more than eight selvedge loops at each side of the blank. Portion A will be of main thread only, portion B of main and splicing threads and the marginal part F of all the threads. The selvedge reinforcement may extend into the unwidened area, e.g. it may extend from the welt throughout the heel bulge. Outer and inner stops 3, 16 for the selvedge reinforcing thread carrier are interconnected by the usual racking worm 17, so that they move together, but the traverse of the reinforcing thread carrier may be adjusted by screw-nut means 19, 20. Where the leg has been knitted down to or nearly to the region where the widening is to occur, a button on the pattern chain causes displacement of a bluffing wheel 9, or stops the machine, or warns the operator to do so, the operator then moving a lever 10, at each end of the machine, to displace the bluffing wheel. Such displacement allows a clawker 6 to engage a widening ratchet 4, provided, in addition to the narrowing ratchet, whenever a button on the pattern chain causes displacement of a roller 13 on to a widening cam 7. The ratchet 4 turns the worm 17, to rack out main carrier stops, outer splicing carrier stops and the interconnected stops 3, 16 of the selvedge-reinforcing thread carriers simultaneously at each end of the machine, by a distance of two needles and when the needles are up. The stops 3 may be pivoted, so that they may be swung out of operative position. Each inner stop 16 is on or forms part of a lever 18 which can be swung up to free the carrier rod of the selvedge-reinforcing carrier. At the end of widening the bluffing wheels 9 are operated to prepare the narrowing ratchet and clawker for operation under pattern chain control. This may be done automatically; or the machine may merely be stopped automatically, manually following a warning, or purely at the judgment of the operator. The bluffing levers may be operated simultaneously from a central control. Specifications 551,615 and 744,038 are referred to.

[Class 6(i)] In a hoeing-machine a motor 4 drives a shaft 6 through a clutch and gearing 5. A lever 15, pivoted on a support forming part of the machine chassis, is connected by a link 9 to a crank 7 mounted on the end of shaft 6. On the other end of lever 15 is pivoted a frame 1, 19,20,21,the tool or tools being fixed on the beam 1. A crank 26 and a hand lever 28 are mounted on a tube 27 which is itself mounted on a shaft 12, the crank 26 being pivoted to the frame. The pivotal connections of the lever 15 and crank 26 to the frame each comprises two rollers so arranged that the tool beam 1 can move transversely. The gear for driving shaft 6 comprises a constantly running loose wheel 33 which meshes with a plate 35 which itself slides on a block mounted on the shaft 6. The plate 35, having two cams 51 mounted at opposite sides, is engaged by means of a lever 39 pivoted on a boss 37 and connected to a spring- loaded lever 40 which is itself connected to a right-angled bracket 42. This bracket is connected to an operating lever 44 the other end of which is connected to a pawl 53 which engages two notches in a plate 55 fastened to shaft 6. Operation of lever 44 disengages this pawl and moves lever 39, so engaging plate 35 with the gear 33. The end of lever 39 engages a notch 46 in a pawl 47. After a half revolution of the cam 51 lifts pawl 47 and disengages lever 39 which returns to its original position, due to spring 59, thus disengaging plate 35, the pawl 53 meanwhile engaging a notch in plate 55 and stopping the motion of shaft 6. Movement of crank 7 raises or lowers the tool beam 1, the shaft 6 being then stopped. Operation of handle 28 moves crank 26 which alters the angle of penetration of the tools. The shaft 6 is mounted in the same case as the differential gearing for the main driving axle. The shaft 6 and main driving axle may both be driven from a common change-speed shaft by means of worm-and-wheel gearing.
