Abstract
An engine starting and stopping device includes a first roller selectively abutting the flywheel of an engine for rotation on a first shaft in response to rotation of the flywheel. A second roller abuts the first roller and rotates in response to rotation of the first roller. A second shaft and an overwind clutch couple the second roller with a third roller such that the third roller rotates in response to rotation of the second roller. The third roller abuts a spring housing and causes rotation of the spring housing in response to rotation of the third roller. A spring is housed within the spring housing and is loaded in response to rotation of the spring housing. The overwind clutch slips when the spring is loaded to a preselected level to protect the spring from overwinding. The spring is selectively unloaded to rotate the spring housing in an unloading direction. Rotation of the spring housing in the unloading direction causes rotation of the engine's crankshaft and startup of the engine.
