- a) a shackle having a long leg and a short leg;
b) a body;
c) means in said body for mounting said shackle in a reciprocal movement between a closed position and an extended open position, in which said short leg of said shackle is outside of said body and said long leg of said shackle can swivel within said body;
d) a latch mechanism in said body to engage with said short leg of said shackle, when said shackle is in it'"'"'s closed position;
e) a lock mechanism in said body operable to disengage said latch mechanism from said short leg of said shackle;
f) an alarm circuit in said body actuates to emit a warning signal when an unauthorized person violates and tampers with said shackle and said body;
said alarm circuit further includes an insulated loop trip wire within said shackle extending between said long leg and said short leg, so that if said insulated loop trip wire in said alarm circuit is broken, said audible alarm will emit the warning signal;
a first insulated contact ring about said long leg of said shackle and electrically connected to a first end of said insulated loop trip wire; and

Abstract
An alarm padlock (10) comprising a shackle (12) having a long leg (14) and a short leg (16). A body (18) is provided. A facility (20) in the body (18) is for mounting the shackle (12) in a reciprocal movement between a closed position and an extended open position, in which the short leg (16) of the shackle (12) is outside of the body (18) and the long leg (14) of the shackle (12) can swivel within the body (18). A latch mechanism (22) in the body (18) engages with the short leg (16) of the shackle (12), when the shackle (12) is in it'"'"'s closed position. A lock mechanism (24) in the body (18) is operable to disengage the latch mechanism (22) from the short leg (16) of the shackle (12). An alarm circuit (26) in the body (18) actuates to emit a warning signal when an unauthorized person violates and tampers with the shackle (12) and the body (18).
