THE NORSE ‘S’ SERIES LATCHES

IMPORTANT OPERATING INSTRUCTIONS

TDS 1-1

V3-0308

– COCK IT BEFORE YOU LOCK IT –

THE SPRING HOOK MECHANISM (HERE SHOWN NON-ENCASED) IS DESIGNED TO

REACH OUT BEYOND THE RECEIVER AND THEN DRAW BACK TO LOCK, OVER CENTER.

These illustrations are shown to acquaint the

user with the operation of the ‘S’ Series

Latches, and also to emphasize the importance

of ‘cocking’ the Latch.

COCKING THE LATCH AFTER UNLOCKING (OR BEFORE LOCKING)

IS VERY IMPORTANT TO ASSURE PROPER FUNCTIONING.

IT IS DONE BY

ROTATING THE LATCH AWAY FROM THE RECEIVER AND AGAINST THE

COCKING RIVET (OR THE BACK OF THE CASE/TYPE 1), UNTIL IT CANNOT

BE ROTATED FURTHER (FIG. 4); FORCING IS UNNECESSARY. NOW THE

HOOK OF THE SPRING IS AT THE MAXIMUM DISTANCE FROM THE HEX

HOLE. THIS ENABLES THE HOOK TO ‘OVER-REACH’ THE RECEIVER PIN

WHEN LOCKING (FIGS. 5 & 6).

‘COCKING’ RIVET EXECUTES THE ‘COCKING’ ACTION – NO FORCE IS NECESSARY

Fig. 5 OPERATING TO LOCK

THIS ‘COCKING’ ACTION FACILITATES THE ‘OVER-REACH’

CONDITION (FIG. 5) WHEN OPERATING TO LOCK, THEREBY

ASSURING PROPER POSITIONING OF THE SPRING HOOK

& RECEIVER PIN ELEMENTS IN THE LOCKED MODE (FIG. 6).

– COCK IT BEFORE YOU LOCK IT –

Continue rotating hook until you feel

Eccentric snap over center into the

locked mode.
