Abstract
1,211,939. Shovelling machines; remotely controlled fastenings. ENVIROTECH CORP. 26 July, 1968 [1 Sept., 1967], ,No. 35722/68. Headings E1F and E2A. A locking device for permitting of the locking together of the relatively movable decks of a turntable when the decks have one particular relationship with one another comprises two spaced apart pawls 21, a stud 40, and an actuator S. The pawls are slidably mounted in a housing C to extend, when the housing is secured to one deck, through a hole in the deck for engagement with the stud, which is mounted on the other deck, preferably in a resilient bush housed in a recess in the deck. The actuator S is a piston cylinder unit having a fixed piston P and a cylinder 30 freely floating about the piston. The construction of the pawls and the relationship between the pawls and the actuator is such as to provide for a lost motion connection therebetween so that when the chamfer 24 on one or other of the pawls is engaged by the stud, as the desks approach said particular relationship with each other, the pawl rules over the stud. The pawl then becomes locked between the studs until the pawls are moved clear of the stud by movement of the cylinder 30 on pressurised fluid being admitted into the cylinder. The turntable can be incorporated in an overthrow type shovelling machine.
