Abstract
A throttle control linkage adapted for connection to the governor mechanism of an engine preferably comprises a slotted quadrant slidably mounted on a pin attached to a support member. The quadrant is held in a selected position on the support member by a frictional device comprising at least one elastomeric member compressed against a side of the quadrant by spring means, preferably in the form of a pair of back-to-back Belleville washers.

A control linkage operatively connected to a control mechanism of an engine comprising
- a control member movably mounted on a support member and operatively connected to said control mechanism,
- a pin secured to said support member,
- an operator's control handle operatively connected to said control member for selectively moving the same on said support member, and
- means, including an annular elastomeric washer mounted on said pin and frictionally engaging a side of said control member, for frictionally holding said control member relative to said support member upon movement of said control handle.
In a control linkage of the type comprising a first member movably mounted on a pin secured to a stationary second member, said first member comprising a quadrant having an arcuate slot formed therein and slidably mounted on said pin and an annular elastomeric washer mounted on said pin to frictionally engage a side of said first member.
