ABSTRACT:
A safety device to stop an engine when the throttle position and the throttle lever position are sufficienty out of synchronism to indicate malfunction. The device includes a pivot means, a throttle lever, and a throttle operating member rotatably supported on said pivot means. Lever bias means biases the throttle lever in a first rotational direction. Bias means effective on the throttle valve biases the throttle operating member in the same direction. Both bias means can be overcome by a sufficient force on the throttle lever. The throttle lever and throttle operating member are abuttable so that they can be rotated in a second direction. They are separable in order that the throttle lever may move away from the throttle operating member if the latter is restrained against movement in response to its bias force. A first and a second switch member are rotatably supported for concentric rotation, one switch member being connected to the throttle lever and the other to the throttle operating member. Switching means has a conductive and a non-conductive condition determined by the relative rotational position of the two members, whereby the switching condition can be changed when the relative positions of the throttle lever and the throttle operating member are out of synchronism.
