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 selecting a predetermined one of the transmission modes and 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. The manually operable means also includes manual actuating means having a plurality of pushbuttons 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 both to the transmitter to select one of the transmission modes as indicated by indicia on the buttons, and also to the spring and generator for initiating driving of the generator upon actuation of the selected button to transmit the selected transmission mode.

Claims

1. A remote electrical signalling system comprising an enclosure having a vertical wall a transmitter means mounted within said enclosure an electromechanical generator connected to said transmitter means for energizing it mounted within said enclosure and manually operably means for operating said generator to energize said transmitter means for a substantial period of time for transmission of a signal, including spring means for driving said generator manual winding lever 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 of at least about 90* generally perpendicular to said wall and drive means connected betweEn said lever means and said spring means for winding of said spring means by said downward movement of said lever means.

2. A signalling system as claimed in claim 1 wherein said manually operable means includes automatic reset means for said manual winding lever.

3. A signalling system as claimed in claim 1, further including manual actuating means having a pushbutton mounted on said enclosure wall behind said overlying winding lever means for exposure by said downward movement of said lever means, said button being connected to said spring means and said generator for initiating driving of said generator by said spring means upon actuation of said button to transmit a signal.

4. A remote electrical signalling system comprising an enclosure having a vertical wall transmitter means having a plurality of selectable transmission modes mounted within said enclosure an electromechanical generator connected to said transmitter means for energizing it mounted within said enclosure and manually operable means for selecting a predetermined one of said transmission modes and operating said generator to energize said transmitter means for a substantial period of time for transmission of said predetermined modes, including spring means for driving said generator manual winding means overlying a portion of said enclosure wall and having a handle, said handle being manually movable relatively to said enclosure wall drive means connected between said winding means and said spring means for winding of said spring means by movement of said winding means and manual actuating means having a plurality of pushbuttons mounted on said enclosure wall, each said button being connected to said transmitter means to select one of said transmission modes indicated by indicia on said buttons and being connected to said spring means and said generator for initiating driving of said generator by said spring means upon actuation of one of said buttons to transmit said transmission mode selected thereby.

5. A signalling system as claimed in claim 4 wherein said manual actuating means pushbuttons are mounted behind and concealed by said winding means for exposure upon winding movement of said handle.

6. A remote wireless electrical signalling system comprising an enclosure having a vertical wall a radio transmitter means having a plurality of selectable transmission modes mounted within said enclosure an electromechanical generator connected to said transmitter means for energizing it mounted within said enclosure and manually operable means for selecting a predetermined one of said transmission modes and operating said generator to energize said transmitter means for a substantial period of time for transmission of said one mode, including multiturn spring means for driving said generator a manual winding lever normally overlying a portion of said enclosure wall and extending vertically thereacross with its lower end pivoted adjacent the bottom of said wall and with its free upper end having a handle, said lever being manually swingable downwardly and away from said wall throughout an arcuate path of about at least 90* generally perpendicular to said wall reset means connected to said lever for automatically returning said lever to its normal position drive means connected between said lever and said spring for multiturn winding of said spring means by said downward movement of said lever manual actuating means having a plurality of pushbuttons mounted on said enclosure wall behind and concealed by said overlying winding lever for exposure by said arcuate movement of said lever, each said button being connected to said transmitter means to select one of said transmission modes indicated by indicia on said buttons and being connected to said spring means and said generator for initiating driving of said generator by said spring means upon actuation of one of said buttons to tranSmit said transmission mode selected thereby.

7. A signalling system as claimed in claim 6 wherein said manual winding lever is pivoted on a horizontal shaft spaced behind and adjacent the bottom of said front wall, said shaft being connected to said drive means and said reset means, with said lever being normally urged by said spring means into its normal position overlying said front wall.
