Abstract
A device for pulling the starter cord of a lawn mower engine utilizes a pulling cable attached to a pulley wheel activated by a high torque electric motor. An elongated base supports an upright post, upon which the motor is mounted. A chute protectively guides the cable as it spans the distance between the pulley wheel and starter cord. A restoring cable, in association with a return wheel and coil spring unwind the pulling cord from the pulley wheel when the motor is deactivated.
Claims4
An auxiliary starting device for an internal combustion engine associated with a mobile machine, said engine having a recoil type starter with a clutch and a pull cord having a proximal extremity attached to said starter, and a free distal extremity equipped with a pull handle, said machine adapted to rest upon a horizontal surface, said starting device comprised of:
- a) a horizontally disposed foundation base elongated between front and rear extremities,
- b) a support post vertically emergent from said base,
- c) an abutment surface associated with the front extremity of said base,
- d) a high torque electric motor mounted upon said support post and having a horizontally directed drive shaft,
- e) a pulley wheel affixed to said drive shaft for rotation in a vertical plane,
- f) a pulling cable having a first extremity attached to said pulley wheel and a second extremity configured to removable associate with said pull cord handle, said cable spanning the distance between said pulley wheel and pull cord handle in a substantially horizontal path,
- g) a chute for protectively guiding said spanning portion of said cable,
- h) a return wheel positioned above said abutment surface and disposed for rotation in a vertical plane,
- i) a return cable having a first extremity, and a second extremity attached to the spanning portion of said pulling cable, said return cable passing forwardly about said return wheel,
- j) elongatable restoring means having a free forward extremity attached to the first extremity of said return cable and an anchored rear extremity, and
- k) resilient restraining means disposed in parallel relationship to said restoring means and adapted to remain inactive until said restoring means has undergone a predetermined elongation.
