Safety stopping device for marine engines

Abstract

The present invention refers to a safety stopping device for marine engines and employs a cord connected at one end to the pilot of the boat and at its other end to the safety device for the grounding of the ignition circuit of the engine either by operating a pushbutton, or by ripping off said cord held between said pushbutton and a retaining head traversing said button and connected by a stem to a metallic head capable by its axial movement to connect two fixed contact terminals interposed in said ignition circuit.

I claim: 
     
       1. A safety device for marine engines comprising an insulating member attachable to a support, a pair of contact terminals mounted in said member and connectable to the engine ignition circuit, a push button slideably connected to said member, a conducting head positioned for connecting said terminals, a stem connected to said head and slideably extending through said push button, a retaining head on said stem positioned adjacent said push button, resilient means between said conducting head and said push button tending to retain said conducting head connecting said terminals, a cord attachably to the pilot of a boat containing said engine and detachably mountable between said push button and said retaining head for withdrawing said conducting head from said terminals whereby when said pilot pulls said cord it is withdrawn from said retaining head and push button allowing said conducting head to connect said terminals and means operable by said pushbutton for moving said conducting head to said terminals when said cord is mounted between said push button and said retaining head. 
     
     
       2. A safety device as claimed in claim 1, wherein said means operable by said pushbutton consists of a sleeve slideably mounted on said stem, engaging said resilient means and positioned for being moved by said pushbutton for compressing said resilient means and thereby moving said conducting head to said terminals. 
     
     
       3. A safety device as claimed in claim 2 including further resilient means tending to move said pushbutton towards said retaining head. 
     
     
       4. A safety device as claimed in claim 2 wherein said sleeve has a shoulder through which said stem slideably extends, said resilient means is a coil spring on said stem and is positioned between said conducting head and said sleeve shoulder, said sleeve has a second shoulder, a second spring is positioned between said sleeve second shoulder and said pushbutton tending to move said pushbutton towards said retaining head. 
     
     
       5. A safety device as claimed in claim 4 including a second sleeve connected to said member and having a shoulder engaging the second shoulder of said first sleeve for limiting the movement of said first sleeve away from said member. 
     
     
       6. A safety device as claimed in claim 4 wherein said first mentioned spring is stronger than said second spring. 
     
     
       7. A safety device for marine engines comprising an insulating member attachable to a support, a pair of contact terminals mounted in said member and connectable to the engine ignition circuit, a pushbutton slideably connected to said member, resilient means tending to move said pushbutton from said member, conducting means resiliently retained in electrical contact with said terminals, means connected to said conducting means and slideably extending through said pushbutton, a cord connectable to the pilot of a boat containing said engine and detachably positioned between said pushbutton and said connecting means for detachably retaining said connecting means in a position withdrawing said conducting means out of contact with said terminals and said pushbutton being capable of moving said conducting means into its terminal contacting position independently of said connecting means.
