Abstract
1308298 Mineral-mining cutter pick assemblies; stud and socket fastenings AUSTIN HOY & Co Ltd 5 March 1970 [18 March 1969] 14288/69 Headings E1F and E2B A shanked tool, e.g. mineral-cutting pick 12, is, when entered into a socket 2 of a holder 1, locked in the socket by a latch 5 housed in a recess surrounding the socket, the latch being of a form capable of surrounding the socket and having operatively connected parts 6, 7 disposed on opposite sides of the socket with the one part 7 being so resiliently biassed with respect to the holder as to cause the other part 6 to lie at least partly in the socket 2. Preferably the parts 6, 7 are parts of an endless member 6 ,7, 13 that is slidably housed in a recess-defining slot extending through the holder from one side to the other thereof. The slot extends normally at an angle other than a right angle to the longitudinal axis of the socket. The biassing of the part 6 is caused by a resilient member 8.
