Abstract
A control lever assembly including a single unitarily formed lever is mounted relative to an actuator such as a valve stem so that generally linear motion applied to one end of the control lever by an operator results in linear motion to the actuator generally at right angles to the linear motion applied to the control lever by the operator. Provision for dampening of unwanted vibratory motion is incorporated in the bracket arrangement mounting the control level.
Claims9
A control lever assembly for effecting linear translation of an actuator of a machine comprising:
- a control lever having one end adapted for pivoted connection to said actuator;
- a first bracket plate adapted for fixture to said machine;
- bearing means fixed in said first bracket for mounting said control lever and allowing rotation and translation of said control lever relative said bracket;
- and
- second bracket means fixed to, and extending generally at right angles to said first bracket plate, said second bracket means for limiting said rotative motion of said control lever to rotation about an axis generally lying in the plane of the first bracket and at right angles to the linear motion of said actuator.
