    • An over-center ejector blade retaining system which automatically locks the ejector blade in a loading position when the ejector blade has been retracted into the load position by operation of the hydraulic cylinder or ram to which it is attached. Movement of the ejector blade into the load position rotates a lock plate attached to the vehicle body into engagement with a locking roller attached to the ejector blade thereby compressing a spring attached to the lock plate. Upon movement of the connection between the lock plate and the spring over the center of rotation of the lock plate, the compressive force on the spring is released and the ejector blade held in the load position. When the ejector blade is moved from the load position to discharge materials, the process is reversed and the lock plate held in an open position for again receiving the locking rollers upon the return of the ejector blade to the load position.
    • 一个中心顶部的推动器叶片保持系统,当喷射器叶片通过与其连接的液压缸或压头的操作而已经缩回到装载位置时,该自动将顶出叶片锁定在装载位置。 推动器叶片到装载位置的移动使附接到车体的锁定板旋转,使其与附接到顶出器叶片的锁定辊接合,从而压缩附接到锁定板的弹簧。 当锁定板和弹簧之间的连接在锁定板的旋转中心上移动时,释放弹簧上的压缩力并且顶出器叶片保持在加载位置。 当喷射器叶片从装载位置移动以排出材料时,该过程被反转,并且锁定板保持在打开位置,以在顶出器叶片返回到装载位置时再次接收锁定辊。

    • A splitter gearbox for a four wheel drive, hydrostatically driven tractor integrates both the input drive train and the output drive train into a single gearbox. The drive mechanism eliminates the need for a separate mechanical gearbox by establishing pre-set fixed displacement settings that are electronically controlled along with the variable displacement of the hydrostatic motor and hydrostatic pump, to provide a smooth power shift through all ranges without requiring the tractor to stop. The drive mechanism is configured so that essentially all components are individually controlled so that the entire power generated by the tractor engine can be diverted to any one of the traction drive, the PTO mechanism, the auxiliary hydraulic drive or, to a somewhat lesser extent, the tractor hydraulic system. The splitter gearbox is mounted to the rear axle housing to allow the sharing of a common oil sump. The input gear set and the output gear set are also within the same common lubrication sump within the splitter gearbox.
    • 用于四轮驱动的分动齿轮箱,静液压拖拉机将输入传动系和输出传动系统集成到单个齿轮箱中。 驱动机构通过建立预先设定的固定位移设置来消除对单独的机械齿轮箱的需要,该设置可与静液压马达和静液压泵的可变排量一起电子控制,以提供所有范围内的平稳功率切换,而不需要拖拉机 停止。 驱动机构被配置为使得基本上所有部件都被单独地控制,使得由拖拉机发动机产生的整个动力可以转移到牵引驱动装置,PTO机构,辅助液压驱动装置中的任何一个,或者在较小程度上, 拖拉机液压系统。 分动齿轮箱安装到后轴壳体,以允许共用一个普通的油底壳。 输入齿轮组和输出齿轮组也位于分动齿轮箱内相同的公共润滑油槽内。

    • A chair control mechanism is provided for use on a chair having a separate seat 14 and backrest 16 that move with respect to a base 12 of the chair. The mechanism 22 includes a housing 26 supported on the base, and brackets 28, 30 secured to the seat and backrest. The seat bracket 28 is supported on the housing for pivotal movement about a horizontally extending front pivot axis 68 between an upright position and a reclining position, and the front pivot axis is located adjacent the front end of the housing. The backrest bracket 30 is supported on the housing for pivotal movement about a horizontally extending rear pivot axis 80 that is located rearward of the front pivot axis. A mechanical linkage 70, 78 is connected between the brackets at a position spaced rearward of the rear pivot axis relative to the housing for transmitting pivoting movement between the brackets, and a spring assembly 32 is connected between the housing and the backrest bracket for biasing the seat and backrest toward the upright position. A forward travel-stop control assembly 38 is provided on the mechanism for adjusting the forward most position of the seat and backrest, as is a tilt control assembly 36 which permits the seat and backrest to be locked against tilting movement. The tilt control assembly 36 includes a locking plate 102 supported on the housing for relative translational movement between an extended position in which the locking plate is received in an aperture of the backrest bracket to lock the backrest bracket from further pivotal movement, and a retracted position removed from the aperture to allow further pivotal movement of the seat and backrest. A locking pawl 106 is supported on a lever 104 of the tilt assembly and engages the lock plate 102 to retract and extend the plate when the lever is rotated. In addition, a clutch is interposed between the actuating lever and the locking pawl for exerting a rotating force on the locking pawl to move the locking pawl from the second position when the actuating lever is rotated. The rotating force of the clutch is smaller than the friction force that is exerted on the locking plate when the pivoting force of the spring assembly 32 is exerted on the locking plate such that the locking plate can only be retracted when the friction force is reduced to a magnitude less than the rotating force.
