Claims8
In an operator's support for a movable machine including a seat support, supporting a horizontally extending seat surface and back resting means for limiting rearward motion of an operator seated on said seat surface, and an armrest laterally offset form said seat surface and upwardly projecting beyond the same, wherein an improved armrest comprising:
- a support plate fixably mounted to said seat support positioned lateral to said seat surface and extending vertically;
- a forward section pivotably mounted to said support plate including a hand controlled lever assembly fixably mounted to said forward section's top surface and first means for pivotally and selectively positioning said forward section within a defined arc;
- a rearward section adjustably mounted to said support plate including a second means for adjustably mounting said rear section to said support plate such that said rear sections angle of incline and vertical position can be selectively adjusted to a complimentary, generally linear alignment to said top surface of said forward section,
- said second means being comprised of a cushion support plate having a generally horizotally extending cushion fixably mounted atop thereto, said cushion support plate having a vertically, downward extending portion, said portion having a first and second vertically extending slot in opposite and generally parallel spaced apart relationship;
- said support plate having a forwardly located horizontal slot and a rearwardly located aperture;
- a bolt, having a bolt head, extending through said first slot in said cushion support plate cushion portion and said horizontal slot in said support plate and is secured therein by a nut;
- a friction washer placed around said bolt and between said cushion support plate portion and said support plate;
- and
- a knob having a threaded stem extending through said second vertical slot in said cushion support plate portion and said aperture in said support plate secured there by a nut.

- said second means being comprised of a cushion support plate having a generally horizontally extending cushion fixably mounted atop thereto, said cushion support plate having a vertically downward extending portion, said portion having a first and second vertically extending slot in opposite and generally parallel spaced apart relationship;
- said support plate having a forwardly located, horizontal slot and rearwardly located aperture;
- a first friction washer;
- a second friction washer;
- an elongated channel member;
- a bolt extending sequentially through said first slot in said cushion support plate portion, said first friction washer, said horizontal slot in said support plate, said second friction washer and thereafter through said channel member;
- a first nut secured to said bolt abutting to said channel member;
- a thrid friction washer;
- a knob having a threaded stem extending sequentially through said second slot in said cushion support plate portion, said third friction washer, said support plate and thereafter through said channel member;
- and
- a second nut secured to said stem abutting to said channel member.
