Abstract
A control assembly primarily intended for use in manually regulating the operating speed of power equipment in which fine adjustments may be obtained by rotating the control knob and rapid changes in speed may be achieved by shifting the knob axially. The assembly includes an outer one-piece sleeve adapted to be mounted upon an instrument panel or engine housing and permanently joined to a flexible casing containing the operating wire or cable. A plunger assembly is rotatably and slidably received within the sleeve, the plunger assembly including a thin-walled plunger tube of flexible material having a control knob ultrasonically welded to one end of the plunger and a swivel connection joining the operating wire at the plunger's opposite end. The swivel connection includes a spherical ball rotatably mounted within the plunger tube for engagement under compressive loads with an enlarged head portion of a swivel connector jointed to the operating wire, the head portion also being rotatably retained within the plunger tube. The side wall of the plunger tube has a generally oval-shaped opening through which a retractable follower (ball) protrudes for engaging the internal threads of the sleeve when vernier adjustment is desired, the width of the opening being slightly less than the diameter of the ball and the ball-retaining edges of the tube defining such width being flexible to allow forceable insertion of the ball into the tube during assembly.
