Abstract
Abstract In an emergency stop switch means for a snowmobile on the like a throttle lever is rotatably mounted on a handle through a bracket thereby controlling an operating lever of carburetor. These levers are connected with each other by an inner wire in an outer sheath the end of which is held in fixed relation while the other is adapted to permit a moving element to slidably move until a contacting element thereof abuts against a counter-element. In an emergency, the throttle lever is released so that a spring compressed between the bracket and the moving element recovers its pressure force and contacts said contacting elements with each other whereby an electric ignition circuit is earthed to stop rotation of a snowmobile engine.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
246 words
An emergency stop switch means adapted to be used for an oversnow vehicle such as a snowmobile or the like having a bracket means rigidly fixed to a handle portion of said vehicle, a throttle lever pivotally supported to said bracket means, a wire for connecting said throttle lever to an operating lever for opening and closing a carburetor valve oF an engine, and an electrical ignition circuit by which said engine is electrically ignited through an ignition coil, said emergency stop switch means comprising; a. an outer sheath having a substantially shorter length than an inner wire for connecting said throttle lever to said operating lever, being adapted to cover said inner wire, b. a fixing means for maintaining one end of said outer sheath in fixed relation to said engine at the side thereof, c. a movable mechanism mounted to said one end of the outer sheath at the side of said throttle lever, said mechanism including a contacting element movable integrally therewith, d. a recessed portion formed in said bracket means and movably receiving said movable mechanism therein, the open end of said recessed portion having said contacting element, e. a spring means mounted between said movable mechanism and said bracket means, and f. an earthing wire for connecting each terminal of said fixed contacting element and said contacting element to said electric circuit of said ignition means and the ground, said earthing wire being connected to the input of said ignition coil.
