摘要： A combination blade clutching and braking mechanism for insuring the safer operation of rotary lawn mowers. The clutching and braking safety mechanism automatically disengages a power clutch while the brake is being engaged. Conversely, when the mower is to be operated, the mechanism automatically disengages the brake and engages the clutch. There is a provision for a dead man control wherein the brake engages automatically and the clutch is disengaged automatically should the operator accidentally lose control of the mower.

摘要： A crop harvesting header for a combine wherein the header includes a transversely elongated frame having opposite side walls. A cutterbar extends between the side walls and is supported from the header frame for floating movement relative thereto as induced by varying ground profile. The cutterbar is connected to the forward ends of a plurality of transversely spaced runners pivotally connected to the header frame. One of the runners is disposed at an end of the header frame adjacent to one of the side walls. Reciprocating drive for the cutterbar is provided by a wobble drive mounted on the end runner and a belt drive therefor mounted on the adjacent side wall. A belt tightener pulley assembly is pivotally mounted on the side wall. A mechanical linkage directly interconnects the pulley assembly with the end runner such that the pulley assembly is shifted in response to movement of the end runner to provide substantially instantaneous change in belt drive geometry created by and to compensate for cutterbar movement relative to the header.

摘要： A coil spring clutch connects a driving hub to a driven sleeve rotatable on the hub and the sleeve drives an output or second driven member through a torque limiting clutch. The spring is readily declutched by arresting rotation of its leading end, as by interposing a stop in the path of an out-turned tang on that end, and is re-engaged by releasing the leading end. Re-engagement is characteristically abrupt and harsh, and the torque-limiting clutch in series with the spring clutch limits torque stress on the spring so that the series assembly is usable in applications which would destroy the spring clutch alone. The torque-limiting clutch may be a fully-releasable centrifugal clutch, in which case, the spring declutching mechanism may be actuated in common with or in response to application of a brake to stop the second driven member, or may be a frictionally-engaged centrifugal clutch or a spring-biased friction clutch. The driven members are desirably mounted on the driving hub in a compact unitary assembly.

摘要： A transmission lever operated switch is incorporated in the electric control circuit for an electric clutch employed in the drive of a tractor mounted mower whereby the electric circuit is deenergized whenever the transmission control lever is placed in its reverse position. The control circuit for the electric clutch includes a seat operated switch whereby the electric circuit will be deenergized whenever the seat is unoccupied. The electric circuit further includes an on-off switch which is interconnected with an ignition circuit switch for an internal combustion engine whereby when the ignition switch is closed, the on-off switch for the electric clutch circuit will be open. Thus, during starting of the engine, the mower blade drive will be inoperative due to the deenergization of the electric clutch control circuit. The electrical interlock control prevents operation of the mower blade during starting of the engine, when the operator's seat is unoccupied and/or when the transmission control is in reverse.
摘要翻译： 传动杆操作开关装在用于拖拉机安装割草机的驱动中的电动离合器的电气控制电路中，从而每当变速器控制杆处于相反的位置时，电路被断电。 用于电动离合器的控制电路包括座椅操作开关，每当座椅未被占用时，电路将被断电。 电路还包括与用于内燃机的点火电路开关互连的开关开关，由此当点火开关闭合时，用于电动离合器电路的开 - 关开关将被打开。 因此，在发动机启动期间，由于电动离合器控制电路的断电，割草机驱动器将不起作用。 电动联锁控制防止在发动机起动时，操作者座椅未被占用和/或变速器控制相反时割草机叶片的操作。

摘要： A self-propelled combine has a forwardly extending, vertically adjustable crop-feeding housing and a transversely elongated, cutter bar type harvesting platform mounted on the forward end of the housing. The platform includes a transversely elongated frame with a transverse flexible cutter bar disposed along the leading edge of the platform floor. The cutter bar is mounted on the platform by a plurality of transversely spaced parallel type linkages that permit independent vertical adjustment of different areas of the cutter bar so that the cutter bar is free to follow the contour of the ground. A wobble type drive mechanism is mounted on one end of the cutter bar and floats therewith, and a sheet-like spring member spans the width of the platform and has its rearward end attached to the platform floor and its forward end connected to the cutter bar, the spring member deflecting downwardly as the cutter bar swings downwardly to partially counterbalance the weight of the cutter bar, the spring member also sealing the area between the floor and the cutter bar. Structure is also provided for adjusting the cutter bar in a fore and aft direction relative to the floor to vary the distance between the cutter bar and the platform auger.
