    摘要： A sway limiting apparatus is disclosed for three-point hitches which has both sway and non-sway settings to either permit limited lateral movement of the draft arms or maintain a constant dimension between the draft arms while the hitch is being lowered or raised. The sway limiting apparatus includes a contoured sliding block which abuts and slides on a complementary bar bracket adjustably mounted to the tractor frame. The sliding block is slotted for adjustment fore and aft along the draft arm, and it includes both inclined surface portions and a tapered surface portion. In the non-sway setting, the inclined surface portions of the sliding block bear against the bar bracket to restrict any side sway while the hitch is being raised or lowered and to maintain the distance between the hitch connection points at a constant dimension. The bar bracket is selectively moved to a second position for the sway setting wherein the tapered surface portion of the sliding block bears against the bar bracket when controlled or restricted sway movement is desirable.

    摘要翻译： 公开了一种用于三点接头的摆动限制装置，其具有摆动和非摆动设置，以允许牵引臂的有限侧向运动或在牵引架被降低或升高时在牵引臂之间保持恒定的尺寸。 摇摆限制装置包括一个轮廓滑动块，其在可调节地安装到拖拉机框架上的互补杆支架上抵接并滑动。 滑块用于沿着牵伸臂前后调节，并且其包括倾斜表面部分和锥形表面部分。 在非摇摆设置中，滑动块的倾斜表面部分抵靠杆支架以限制任何侧摆动，同时牵引力被升高或降低，并且将连接点之间的距离保持在恒定的尺寸。 杆支架选择性地移动到用于摆动设置的第二位置，其中当需要受控或限制的摆动运动时，滑动块的锥形表面部分抵靠杆支架。

    摘要： A hammer drill has a motor which drives an axially displaceable intermediate gear mounted in an intermediate gear arrangement. An impact mechanism is formed by including interacting impact cams between either the intermediate gear and the housing, or the motor armature shaft and the housing to generate a reciprocating motion on an output spindle or shaft. A spindle locking mechanism is included which causes an intermediate gear to be disengageable with respect to the output shaft, while still permitting the impact mechanism to be engaged. Such an arrangement allows the hammer drill to operate in a hammer-only or chipping mode.

    摘要： A hammer drill has a motor disposed in a housing, and the motor has a rotatable armature shaft. A pinion at an end of the armature shaft drives an axially displaceable intermediate gear mounted on an intermediate shaft. An intermediate pinion is mounted for rotation with the intermediate gear and drives an output gear fixed about the midsection of an axially displaceable output shaft. The intermediate gear has input and output faces. The input face is associated with a first cam mechanism for generating reciprocating motion. The output face is engageable with an impact face of the output gear to transmit axial displacement therebetween. A second cam mechanism is affixed to the housing and axially spaced from the first cam mechanism. The first and second cam mechanisms are engageable by sufficiently axially displacing the output shaft so that the output gear impact face abuts the intermediate gear output face axially displacing the intermediate gear so that the first and second cam mechanisms abut each other. The first and second cam mechanisms are configured with respect to each other to generate reciprocating motion and cause the intermediate gear to reciprocate axially as the first cam mechanism rotates relative to the second cam mechanism while the first and second cam mechanisms are engaged. The output face of the intermediate gear transmits the reciprocating motion to the output gear impact face to axially reciprocate the output shaft as it rotates.

    摘要： A drill assembly including a drill and depth stop assembly is disclosed. The drill includes a housing, an electric motor and a chuck operatively driven by the electric motor about a drill axis. The depth stop assembly includes a depth stop rod, a mounting block, a fastener and a rotatable handle. The mounting block has a mounting surface adapted to cooperate with the housing, a first aperture spaced from the mounting surface for supporting the depth stop rod generally parallel to the drill axis, and a second aperture extending about a fastener axis generally normal the mounting surface. The fastener extends through the mounting block second aperture about the fastener axis and has two ends respectively cooperative with the housing and the handle to releasably entrap the mounting block therebetween to enable a user to adjustably position the depth stop rod relative to the housing. Preferably the fastener threadedly attaches to a threaded aperture in the drill housing. Ideally, the mounting block includes first and second mounting block halves which releasably clamp about the depth stop rod.
