Switching mechanism for fluid-operated gear shifters
First Claim
1. In an automotive vehicle having traction wheels driven from an engine via a transmission provided with electrically controllable fluid-operated gear-shifting means, said vehicle being further provided with a fluid-operated working implement powered by the engine,the combination therewith of a switching mechanism for the control of said implement and said gear-shifting means comprising:
- a lever universally jointed on a base for selective pivotal motion into any of a plurality of implement-controlling positions;
a housing rigid with said lever;
a knob above said base having a stem journaled in said housing for selective rotation into a plurality of transmission-controlling angular positions relative to said lever; and
a plurality of microswitches in said housing actuatable by cam means on said stem to close different control circuits for said gear-shifting means in said angular positions.

Abstract
A shift lever for the selective actuation of power tools on a utility carries a rotary and axially shiftable knob which can be indexed by ball checks in a plurality of angular positions to establish different speed ratios of the vehicular transmission by actuating respective microswitches through cams bearing upon mobile bodies which are lodged in apertures of a stationary collar surrounding an extension of the knob. A rocker switch on that knob can be flipped by the fingers of the operator to switch between forward and reverse drive.
