Abstract

913,433. Toggle mechanisms. KENNARD, A. D. Dec. 30, 1958 [Sept. 30, 1957], No. 30584/57. Class 80 (3). [Also in Groups XXII and XXX] Means for moving cores in a casting apparatus &c. comprises a ram 3 moved initially by hydraulic or pneumatic means 2 and having a final motion effected by toggle links 6. The centre pivot 12 of the links is. attached to a piston 13 by links 10. The togle links prevent movement of the corepins when metal is injected into the dies.
