Emergency signalling transmitter

Claim 1

In a remote electrical signalling system comprising an enclosure having a vertical wall, a transmitter having a plurality of selectable transmission modes mounted within said enclosure, and an electromechanical generator for energizing the transmitter also mounted within said enclosure, that improvement which consists of: manually operable means for operating said generator to energize said transmitter for transmission of a signal, including manual operating lever means normally in a first position overlying a portion of said enclosure wall with its lower end pivoted adjacent the bottom of said wall and with its free upper end having a handle, said lever means being manually swingable downwardly and away from said front wall throughout an arcuate path to a second position exposing said wall, lever operated actuating means connected between said lever means and said generator actuating operation of said generator only upon return of said lever means from said second position to said normal first overlying position, and selecting means having a plurality of push buttons mounted on said wall behind said lever means for exposure by said downward arcuate movement of said lever means, each button being connected by said selecting means to said transmitter to select one of said transmission modes, indicated by indicia provided adjacent said buttons, upon actuation of one of said buttons, and said selecting means being changeable to select a different one of said transmission modes by actuation of a second one of said buttons, but only prior to return of said lever means to said first overlying position, and the consequent actuation of the operation of said generator by said actuating means and the energization of said transmitter for transmission of a signal according to the transmission modes selected upon actuation of one of said buttons.
