Abstract

1,115,411. Pick-securing means; stud & socket fastenings. MATHIAS SPENCER & SONS Ltd. 29 Jan., 1965 [8 Nov., 1963], No. 44105/63. Headings E1F and E2B. In a pick box assembly the means for positively locking a pin to retain a pick shank in a pick box is protectively housed within the pin-retaining bore in the box and involves a camming surface and a cam follower, one being on the pin and the other on a plug secured in one end of the pin-retaining bore. The pin is spring-biased against the plug.
