Lift Off Cover

Lift-off cover 10 is pivotally mounted with respect to machine frame 11 in such a manner that cover 10 can be tilted back slightly and then be moved backwardly to free it from frame 11.

Cover 10 has U-shaped guide rail 12 embracing rail 13 which is circular in cross-section and fixed to frame 11. Rail 12 has pin 14 extending through it and received in slot 15 in rail 13. Cover 10, on each side, has latch bracket 16 carrying rubber stop 17 resting on plate portion 18 of frame 11 when cover 10 is in place on such frame.

Latch 19 is reciprocably carried by frame 11 adjacent each bracket 16 and has compression spring 20 holding it in overlying relationship to bracket 16 when cover 10 is in place. Manual actuating pin 21 is fixed in each latch 19. Each bracket 16 has a locating pin 22 fixed to it and received by perforated guide pin bracket 23. Each guide pin bracket 23 is fixed to portion 18 by a screw 24 extending through slot 25 in bracket 23 allowing adjustment of bracket 23 either longitudinally of portion 18 or slightly transversely of it. Rail 12 has downwardly extending dimples 26 bearing on rail 13 when cover 10 is in place to provide a close fit of rail 12 on rail 13.

Latches 19 can be released from their brackets 16 by pins 21 to allow cover 10 to rotate through a slight angle about rail 12. Cover 10 can then be removed from frame 11 by a slight additional backward movement to disassociate rail 12 from rail 13. Cover 10 is replaced by opposit...
