Patent GB-578596-A (GB)
Abstract: 578,596. Converting rotary into reciprocating motion. BROOK, H. R. Nov. 4, 1943, No. 18351. [Classes 80 (i) and 80 (ii)] Consists in means for imparting a reciprocating motion to the cam box of a fiat or straight bar hand-actuated knitting machine, such means being applicable also to shaping machines, planers, gang metal saws &c. A driving shaft 1, extending across parts 1a of a knitting machine frame, is driven from a power source through a sprocket 2 and carries a driving disc 3 secured to the shaft which has limited axial movement. Freely. mounted on this shaft on opposite sides of the disc are sprocket wheels 4, 5 between which and the disc are discs of friction material 6 through which the disc 3 may drive either of the sprockets when the shaft is moved axially in the appropriate direction. An endless chain 7 passes over the sprockets 4, 5 and over two idler sprockets 8, 9 the upper stretch of the chain being connected to the part 10 which is to be reciprocated. Link-work to operate the two clutches 6 is actuated by two stop members 12, 13 adjustably secured to a slide bar 14 which may be moved by a hand lever 17 to reverse the movement of the part 10 at any desired point in its travel. To disconnect the drive after the part has made a predetermined number of reciprocations, the lever 17 is connected to a ratchet wheel 18 by a pawl 19 which gives the wheel 18 a step-bystep rotation. A chain wheel 18a is fixed to the wheel 18 and over it and idlers 21, 22, passes a chain 20 carrying trip members 23. The linkwork shown in Fig. 1 for reciprocating the shaft 1 includes a knuckle 25 pivoted on a fixed pivot 25a and connected by a rod 15 to the bar 14. Links 26 are pivoted to the knuckle 25 and to links 27a the latter carrying links 32, 29.
