Purse alarm

Claim 1

An alarm for purses and the like, comprising a. a transferable housing, b. detachable connecting means attached to said housing for securing said housing to said purse, c. an electrically conductive flexible cord having at least three leads connected at one end to said housing and at the other end being formed with a fixed closed loop. d. at least a portion of said core being detachable from said housing, e. an alarm, a battery and a normally armed switching circuit including a transistor mounted in said housing and electrically connected to said cord and normally providing a small and continuous flow of current through said cord, f. current control means including a silicon controlled rectifier connected to said alarm, said battery, and to said transistor in said circuit whereby disconnection of said cord will actuate said circuit to thereby cause said rectifier to conduct current through said alarm, g. said housing being formed with a restricted opening therein and a normally closed reset switch mounted recessed within said housing in registration with said opening, h. a pair of said leads in said cord normally completing a circuit between one side of said battery, the base of said transistor and the cathode of said rectifier, a third lead in said cord being connected to the collector of said transistor and the gate of said rectifier whereby a short circuit between said third lead and one of said leads in said pair of leads will bias said rectifier into a conducting state.
