Abstract

An enclosed batteryless remote wireless electrical signalling system with a radio transmitter having a plurality of selectable transmission modes and an electromechanical generator driven by a spring mounted within the enclosure. Manually operable means are provided for operating the generator to energize the transmitter means for a substantial period of time for transmission of the selected mode. Such means includes a manual winding lever overlying a portion of the front wall of the enclosure with its lower end pivoted adjacent the bottom of the front wall and with its free upper end having a handle. The lever is manually swingable downwardly and away from said front wall throughout an arcuate path of about 90* generally perpendicular to said front wall to wind the spring. Selecting means are provided having a plurality of push buttons contained in an electrical switch mounted on the enclosure front wall behind and normally concealed by the overlying winding lever for exposure by the downward arcuate movement of the lever, each button being connected to the transmitter to select one of the transmission modes as indicated by indicia provided adjacent said buttons. Further included in the manually operated means is a cam operated linkage for initiating driving of the generator upon return of the manual winding lever to the normal vertical position adjacent said front wall to transmit the selected transmission mode.

Claims

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.

2. A signalling system as claimed in claim 1 wherein locking means are provided for cooperation with said manually operable means to prevent, after return of said leVer means to said first position and actuation of the operation of said generator by said actuating means, operation of said manual winding lever and selection of a second transmission mode until a first selected signal has been completely transmitted.
