摘要： A connecting member slidably couples an elongated, resilient rod to a movable frame of a variable speed friction drive mechanism. The member is elongated and has an elongated bore non-parallel to the longitudinal axis of the member which slidably receives the resilient rod. The member is selectively rotatable on the frame, and thus the restoring force of the rod adjustably positions the frame at any one of a number of preselected positions wherein the resilient rod is unstressed and in its normal configuration. The member provides means for precise, selective adjustment of the control linkage for the drive mechanism while preventing stress-related failure of the rod.
摘要翻译：连接构件将细长的弹性杆可滑动地联接到可变速度的摩擦驱动机构的可动框架上。构件是细长的并且具有不平行于构件的纵向轴线的细长孔，其可滑动地容纳弹性杆。构件可选择性地在框架上旋转，因此杆的恢复力可将框架可调节地定位在多个预定位置中的任何一个位置，其中弹性杆不受应力并处于其正常构型。该构件提供了用于精确，选择性地调节驱动机构的控制联动装置同时防止杆的应力相关故障的装置。

摘要： A self-propelled, walk-behind traction vehicle includes a power source, a pair of drive wheels and an improved operator-manipulated drive control mechanism for selectively coupling the drive wheels to the power source in a manner that allows the operator to control propulsion and steering of the vehicles. The drive control mechanism includes a friction drive unit having a pair of reversible, variable speed transmissions associated with respective ones of the drive wheels for selectively coupling the drive wheels to the power source. The control mechanism further includes a pair of independently swingable control handles configured to be gripped by the operator and operably coupled to respective ones of the transmissions so that the speed and direction of rotation of each of the drive wheels is controlled by swinging a respective one of the handles.

摘要： An automatic tensioner to be used with a drive train of a self-propelled mower for drivingly connecting a ground wheel to the mower transmission, wherein the tensioner includes tensioning mechanism, which may be constructed as a spring biased idler arm having an idler member rotatably mounted thereon, to apply a tensioning force against the flexible element of the drive. The tensioner further includes an anti-slackening assembly having an elongated takeup rod being pivotally coupled with the idler arm at one end thereof so that the takeup rod moves generally with the idler arm, as the arm moves in a tensioning direction and opposed slackening direction. The anti-slackening assembly also includes a swingable control tab having an aperture receiving the other end of the takeup rod. The tensioner is constructed so that the takeup rod engages the aperture of the control tab to swing the control tab to a disposition in which the takeup rod is generally aligned with the aperture permitting relative movement therebetween as the idler arm and takeup rod move in the tensioning direction, and to alternatively swing the control tab to a locking position in which the takeup rod is canted within the aperture to prevent the idler arm and takeup rod from moving in the slackening direction.

摘要： A variable speed friction drive apparatus for a lawn mower includes a pair of drive cones supported by a frame for rotational movement about a common first axis, and a pair of drums supported by carriages for rotation about axes transverse to the lengths of the carriages. Each carriage is supported on the frame for movement between a neutral position in which the associated drum is disengaged from either of the cones and a plurality of driving positions in which the drum engages either of the cones. A universal joint connects the rear end of each carriage to the frame for universal pivotal movement about the joint, and both ends of each carriage are independently biased toward the neutral position.

摘要： A walk-behind rotary lawn mower having a sliding drawer type grass catcher box mounted directly on the rear part of the deck behind the engine and between the U-shaped handle and rear wheels. A cover fixedly mounted on the handle closes the top of the box. A vertical tube carries the cut grass-air mix from below the mower deck up to against the cover. The cover is provided with an integral arcuate chute for causing the cut grass-air mix to swirl around in the box so the grass can fall by gravity into the box. The tube, cover and box are a closed air system and the air is exhausted to the atmosphere through vents in the cover which face in directions away from a user positioned behind the mower. The tube, cover and box are constructed from air impermeable plastic, and the box can be lined with a conventional store-bought throwaway type plastic garbage or leaf collecting bag.
