Safety receptacle for a two-piece duplex

Claim 1

A safety receptacle and plug comprising: (a) a male plug including two parallel blades extending outward from said plug at one plug end and an elongated pin interposed between said blades and extending from said plug end parallel to said blades; and, (b) a female receptacle including: (i) a housing having at least one pair of hot/neutral slots encased therein and adapted to receive said male plug's male blades; (ii) a sleeve located in said housing, said sleeve having two ends and four sides and including at one sleeve end an extension to abut said pin when said plug's blades are received by said receptacle; (iii) a nonconductive tensioned rack including a spring for tensioning, said rack in linear alignment to and abutting one of said sleeve's sides; (iv) a nonconductive pinion workably engaging said rack; and, (v) a conductive pair of pivotal arms located in a plane parallel to said hot/neutral slots, each said arm having an inner and an outer side and two ends, each said arm connected to a first arm end to an electrical source and to said pinion, each said arm's other end aligned to pivotably make electrical contact with one each of said hot/neutral slots, so that when said male plug is inserted in said housing, said pin engages said sleeve extension and presses against said extension causing said rack to retract, whreby said pinion rotates and pivots each said arm into contact with said hot/neutral slot to thereby render said socket live, and removal of said plug, and consequently said pin, allows said spring to relax, thereby urging said rack forward to cause each said arm to pivot and discontinue contact with said slot, thereby breaking electrical contact and rendering said socket dead.
