Abstract
Abstract A Bowden cable control for lawn mower engines and the like is provided. The control includes a control plate and a control knob; a retaining flange is integrally formed with the knob to engage the underside of the plate. Embossments formed at the ends of the knob stress the knob to provide a resilient slide control action throughout a wide range of environmental conditions.

Claim 1
Independent Claim
222 words
In a slide control for operating a Bowden cable and the like, said control including a control plate having a top side, an underside, and a slot formed therein, the improvement comprising a control knob having a finger tab, a base plate, and a foot integrally formed with the base plate, the foot including a stem portion substantially as wide as the major portion of the control plate slot and a flange portion wider than the stem portion for engaging the underside of the control plate adjacent the slot, the free distance between the bottom of the base plate and the top of the flange portion substantially equaling the thickness of the control plate adjacent the slot, the control knob further including an embossment at each end of said base plate for engaging the top side of the control plate at a distance from the stem portion of the foot, the free distance between the bottom of the embossment and the top of the flange portion being less than the thickness of the control plate adjacenT the slot for placing resilient bending stress in the control knob base plate when the control knob engages the control plate, each embossment including an enlarged guide lug for engaging the control plate slot to encourage smooth translational motion of the control knob across the plate.
