Control handle arrangement for power takeoff valve

A control handle arrangement for selectively moving a reciprocable valve member, comprising:

• handle bracket means adapted for mounting in association with said valve member;
• control handle means adapted to be mounted in association with said bracket means, said handle means being adapted for releasable operative connection with said valve member in first and second positions of said handle with respect to said valve member and said bracket means, whereby movement of said handle means in a first direction moves said valve member from a first neutral position thereof to a second position thereof;
• and
• selectively operable retaining means for retaining said handle in a position in which said valve member is maintained in said second position thereof, said retaining means being operable when said handle means is operatively connected to said valve member in said first position of said handle means, said retaining means being inoperable when said handle means is operatively connected with said valve member in said second position of said handle means,
• said handle means being movable in a second direction transverse to said first direction for operating said retaining means,
• said bracket means including a first wall portion defining a guide slot within which said handle means is movable in said first direction, said retaining means comprising detent means defined by said first wall portion in association with said guide slot;
• said retaining means further comprising a portion of said handle means of relatively reduced cross-section;
• said retaining means operating such that in said first position of said handle means, said reduced portion is receiveable within said detent means, while in said second position of said handle means said reduced portion is not receivable within said detent means.

A control handle arrangement for selectively moving a reciprocable valve spool of a self-centering valve on an associated material handling implement, comprising:

• a handle bracket adapted for mounting in association with said valve, and including a base portion through which said valve spool is adapted to extend, and further including spaced apart, first and second wall portions extending from said base portion on respective opposite sides of said valve spool;
• a control handle adapted to extend through said first and second wall portions and move within a guide slot defined by said first wall portion as said handle pivots with respect to said second wall portion;
• means for releasably pivotally connecting said control handle with said valve spool so that said valve spool is movable from a first neutral position to a second position as said handle is moved in said guide slot;
• and
• means for selectively retaining said control handle in a position wherein said valve spool is maintained in said second position thereof, said retaining means including a detent notch defined by said first wall portion of said handle bracket and opening into said guide slot, said retaining means further including a portion of said control handle of relatively reduced cross-section, whereby said reduced portion is receivable within said detent notch in a first position of said control handle with respect to said valve spool for maintaining said valve spool in said second position thereof, while in a second position of said handle with respect to said valve spool said reduced portion is not receivable within said detent notch.
