Abstract
Abstract A starter assist apparatus is taught for use in combination with a recoil-type starter operably connected to an internal combustion engine. Recoil-type starters include a recoil pulley biased in recoil direction, and a cable wrapped about the recoil pulley with the outermost end of the cable extending outwardly for brisk withdrawal to impart a starting impulse for the internal combustion engine. The arrangement of the new starter assist apparatus is such that, first of all, the cable from the recoil pulley is fastened to a frame element or to a special pivotable lever carrying a bight pulley assembly. When the cable is affixed to the lever, an idler pulley for entraining the cable is fastened to a frame element. The bight pulley assembly engages a bight of the cable between the fastening point and the recoil pulley wrapping, so that shifting of the bight pulley assembly in response to shifting of the lever draws out cable to impart a starting impulse to the engine. A foot pedal is connected to the lever is spaced relationship from the fulcrum of it so that pivoting is accomplished by foot pressure. Limit stops restrict the range of pivot of the lever so as to reduce wear and tear of the recoil mechanism. Alignment of the elements, or a special guide member, serves to maintain the cable, during withdrawal and recoil of it with respect to the recoil mechanism, in substantially the same plane as the wrapping of that cable about the recoil pulley. This relationship is at least maintained for a sufficient distance beyond the rims of the recoil pulley to prevent abrading draw of the cable laterally over a rim of the recoil pulley.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
380 words
In combination with a recoil-type starter operably connected to an internal combustion engine, wherein the recoil-type starter includes a recoil pulley biased in recoil direction, and a cable wrapped about the recoil pulley with the outermost end of the cable extending outwardly for withdrawal to effect rotation of the recoil pulley in a direction opposite to the recoil direction and simultaneously effect a starting impulse for the internal combustion engine, a starter assist apparatus comprising (i) fastening means holding the outermost end of said cable, (ii) a shiftable bight pulley assembly engaging a bight of said cable between said fastening means and said recoil pulley wrapping thereof, said bight pulley assembly comprising a grooved bight pulley, (iii) a lever member, said shiftable bight pulley assembly being operably affixed to said lever member, (iv) means mounting said lever meMber at a pivot fulcrum in spaced relationship from said shiftable bight pulley assembly, so that pivotal movement of said lever member effects shifting of said shiftable bight pulley assembly, (v) a foot pedal operably connected to said lever member in spaced relationship from said mounting means, so that foot pressure on said foot pedal pivots said lever member and shifts said bight pulley assembly to withdraw a length of cable from said recoil pulley greater than the distance said bight pulley assembly is shifted, (vi) stop means limiting the range of outward shift movement of said bight pulley assembly during said withdrawal of cable, (vii) means maintaining said cable, during withdrawal and recoil thereof, in substantially the same plane as the wrapping thereof about said recoil pulley for at least a sufficient distance beyond the rims of said recoil pulley to prevent abrading draw of said cable laterally over a rim of said recoil pulley, (viii) a stop member limiting the range of return movement of said lever member and bight pulley assembly during recoil of said cable on said recoil pulley, and (ix) spring means biasing said bight pulley assembly in a cable withdrawn direction from said recoil pulley, said bight pulley assembly being continually biased in said cable withdrawn direction throughout the range of said shift movement thereof, the recoil biasing of said recoil pulley being greater than the biasing of said bight pulley assembly in said cable withdrawn direction.
