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.
