Pull starters for cranking an internal combustion engine in a cranking direction include clutch driven means mounted upon a rotatable part of the engine which is rotated during starting by driving clutch means mounted for rotation by a starting pulley. The starting pulley is a spring retrieved pulley which causes rotation of the driving clutch means. The pulley carries projecting clutch disengagement means to forceably disengage the driving clutch means from the clutch driven means if normal disengagement does not occur. The starting pulley is provided with a spring retaining collar extending from one surface of the pulley, and this collar is provided with an outer spring engaging surface. An open ended spring retaining channel is formed beneath the collar outer surface, and a cam step surface extends inwardly from the outer surface to guide a spring into the open end of the channel. Also, the collar is formed to lock a spring end within the spring retaining channel.
In a pull starter for cranking an internal combustion engine in a cranking direction which includes a clutch driven means mounted upon a rotatable part of said engine, driving clutch means mounted for rotation by a starting pulley and movable to an engaged position with said clutch driven means in response to rotation of the starting pulley in the cranking direction, a starting pulley assembly means comprising a spring retrieved starting pulley for rotating said driving clutch means, and clutch disengagement means mounted upon said starting pulley and positioned to engage said driving clutch means only if said driving clutch means is rotated in the cranking direction by said clutch driven means by the failure of said driving clutch means to disengage from said clutch driven means when said driving clutch means is no longer rotated by said starting pulley.
In a pull starter for cranking an internal combustion engine in a cranking direction which includes a clutch driven means mounted upon a rotatably part of said engine, driving clutch means mounted for rotation by a starting pulley and movable to an engaged position with said clutch driven means in response to rotation of the starting pulley in the cranking direction, a starting pulley assembly means comprising a spring retrieved starting pulley for rotating said driving clutch means, and clutch disengagement means mounted upon said starting pulley to engage said driving clutch means when said driving clutch means is rotated in the cranking direction by said clutch driven means, said starting pulley assembly means including a spring retaining collar extending from a side surface of said starting pulley and having a spring engaging outer surface extending from the side surface of said starting pulley outwardly toward the terminal end of said collar, said collar having a spring retaining channel formed therein with an open end to receive the end of a spring, said spring retaining channel extending for a distance lengthwise beneath the outer surface of said collar and in spaced relation thereto, the collar being cut away to provide a cam step surface extending inwardly from the outer suface of said collar to the open end of said spring retaining channel.
A starting pulley for operating the clutch members of a pull starter for an internal combustion engine comprising a substantially circular pulley body, a shaft receiving opening formed through the center of said pulley body, a substantially cylindrical annular collar extending outwardly from said pulley body around said shaft receiving opening, the circumferential surface of said collar being adapted to engage a rewind spring, said collar including a spring retaining, open ended channel formed therein and extending for a distance beneath and in spaced relationship to the circumferential surface of the collar, and a ramp surface formed in said collar and extending between the open end of said spring retaining channel and the circumferential surface of said collar for guiding a spring into said spring retaining channel.
