Abstract

706,844. Crank mechanism. G. D. SOC. ANON. Sept. 15, 1950 [Sept. 15, 1949], No. 22782/50. Class 80 (3) A crank mechanism for providing a period of rest at a dead-centre position comprises a primary crankpin 4 on a crank 3 of a shaft 2 on which is pivoted a lever 5. The lever 5 carries at its other end a secondary crankpin 6, to which is coupled a connecting rod 10 for operating a slide 13, and a roller 8 which engages in a cam groove 9. The crank 3 in rotating drags the lever 5 behind it and the cam groove is shaped with a concave portion to vary the position of the secondary crankpin 6 to provide a period of rest of the slide 13 at the top dead-centre position, the concave portion of the cam groove being of a radius corresponding to the length of the connecting rod 10. By provideing a convex radiused portion of the groove at the bottom a rest period of the slide 13 at bottom dead-centre is obtained.
