Abstract: An adjustment device for automatically adjusting clearance between components of a brake mechanism including a movable member operable by a vehicle operator to move a braking member from a clearance position into contact with a rotating member. The adjustment device includes a threaded shaft having a portion operatively coupled to a tubular member by means of a clutch. As wear occurs in the brake mechanism, the clutch permits relative movement between the threaded shaft and the tubular member in a first direction of movement of the movable member, and transmits movement therebetween in a second direction of movement of the movable member to cause rotation of the threaded shaft and maintain a constant clearance.

Abstract: A control lever mechanism for controlling the operative position of a plurality of control valves of a hydraulic distributor by coupling movement of a control lever into selected motion of a pair of rotatable output shafts controlling operation of the valves. Movement of the control lever in planes extending in a longitudinal, transverse, or combination of these directions, is transmitted to the output shaft through interconnecting linkages employing a plurality of spherical joints. The control lever mechanism also includes provisions to protect the linkages from being adversely affected by the introduction of foreign substances such as dirt and other elements.

Abstract: An air pressurizing system including a double acting pneumatic cylinder operatively connected to hydraulic actuated equipment for operation thereby in response to movement thereof to pressurize a hydraulic fluid tank or reservoir and control the air pressure coupled into the hydraulic fluid tank.

Abstract: A hydraulic system which is monitored to control the application of fluid power in response to the temperature of the hydraulic fluid and a temperature responsive valve for use in the hydraulic fluid circuit to monitor the temperature of the fluid to control the application of fluid power to components of the system.
