Abstract

488,613. Knitting-machines. MORTON, SIR J., HANNAY, R. S. E., and CARTER, W. L. C. Jan. 7, 1937, No. 482. [Class 74 (ii)] [Also in Group XXIV] Mechanism for imparting an irregular to- and-fro motion to a needle bar, presser bar, sinker bar or other knitting part of a warp machine comprises an eccentric having an operative connection with the knitting part and a cam arranged to act on the connection to modify the motion transmitted therethrough by the eccentric. As shown in Fig. 1, arms 3 supporting a needle bar 1 are connected to a fulcrum shaft 4 and provided with a floating lever 6 which is connected at opposite ends to an eccentric rod 8 and to a cam-operated lever 10 having rollers 13 for engaging cams 14, 15. When the motion imparted by the cams is superposed on the simple harmonic motion of the eccentric, the to-and-fro motion includes two pauses, one for the warp guides to lay their warps on the needles and the other when the presser bar acts on the beards. In a modified construction for actuating the presser bar, the cam-operated levers are mounted on the eccentric shaft which is driven at the same speed as the cam-shaft. In Fig. 3, levers 43 secured to a fulcrum shaft 44 and carrying a sinker bar 42 are provided with floating levers 45, each of which is connected to an adjustable eccentric rod 49 and to a lever 51 that is held against a cam 55 by a spring 56. The eccentric shaft rotates at twice the speed of the camshaft and the sinker bar receives a quick advance stroke and a slower return movement. In a modification, the cam-actuated levers are carried by the eccentric shaft. The knitting part may also be operated by means of cams 103, 104 and two eccentrics 101, 102, as shown in Fig. 5, the motions due to the eccentric 102 and cams 103, 104 being combined and the resultant motion further combined with the motion due to the eccentric 101. The final resultant motion is communicated to the knitting part, e.g. the warp guide bars described in Specification 470,783, by levers 118, 120 and links 119. A counter-weight may be included in the mechanism, for increasing and reducing the load on the cams at predetermined periods.
