Abstract
Abstract An improved manacle comprising two wristlet casings connected by a hinge, a receiver secured in one of said casings to receive the control signal from a transmitter, and an electric discharger to produce an electric shock voltage characterizing in said control signal is received by the receiver and converted to control said discharger to produce a high voltage shock to the prisoner with the manacle through an electrode, and in said hinge connecting the casings comprises a channel through the hinge body and the T-shaped connectors for the lead wires connecting circuits in the wristlet casings to pass without damage.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
An improved manacle comprising two wristlet casings connected by a hinge, a receiver secured in one of said casings to receive the control signal from a transmitter, and an electric discharger controled by said control signal to produce an electric shock voltage applied to an electrode in a hooked portion of said casing whereby the electric shock is applied to the prisoner through said electrode if he is locked with the manacle.
Claim 2
Dependent Claim
72 words
An improved manacle comprising two wristlet casings connected by a hinge, a receiver secured in one of said casings to receive the control signal from a transmitter, and an electric discharger controled by said control signal to produce an electric shock voltage applied to an electrode in a hooked portion of said casing whereby the electric shock is applied to the prisoner through said electrode if he is locked with the manacle.
Claim 3
Dependent Claim
108 words
An improved manacle according to claim 1 wherein said hinge to connect two wristlet casings comprises a solid rectangular hinge body having four protrusive plates extending from the ends thereof with each said plate having a hole formed thereon, a pair of T-shaped connectors pivotally connected to said hinge body each further comprises a first cylindrical portion with a hole drilled centrally and axially therein and a second cylindrical portion with its one end welded radially on said first cylindrical portion, and a channel formed axially through the T-shaped connectors and the hinge body for the lead wires connecting circuits in the wristlet casings to pass without damage.
Claim 4
Dependent Claim
44 words
An improved manacle according to claim 1 wherein said transmitter supplied by a battery and controlled with a micro switch, consists a low frequency signal generator to produce an ossilated signal which is carried by a high frequency carrier and transmitted through an antenna.
Claim 5
Dependent Claim
61 words
An improved manacle according to claim 1 wherein said electrode is clamped by two insulators forming a combined assembly which is conformed in shape with the hooked portion of the wristlet casing and adopted therein to receive the output shock voltage produced by the discharger and transfer the same to the wrist of the prisoner who is locked with the manacle.
Claim 6
Dependent Claim
39 words
An improved manacle according to claim 1 wherein said receiver comprises a micro switch which is equipped on the wall of the wristlet casing and controlled to be on when the movable hooked portion is locked to the casing.
