摘要： A preferred embodiment of a rotary tool reciprocating motion conversion attachment for a rotary power hand tool is described which is configured to be attached to a nose portion of the hand tool housing. The attachment has a rotary drive train in a housing that is connectable to the output shaft of the hand tool, the drive train driving a barrel cam having an exterior cam groove. A cam follower rides in the cam groove and produces reciprocating motion, with the cam follower being part of a cam follower assembly to which an implement holder is attached. The preferred embodiment has a cam groove configuration which causes the implement holder to move slower during a cutting stroke and faster during a return stroke, thereby tending to optimize the operation of the cutting implement. The preferred embodiment also includes a planetary gear set for reducing the rotational speed of the hand tool output shaft to reduce the speed of reciprocation of the attachment.
摘要翻译：描述了用于旋转动力手动工具的旋转工具往复运动转换附件的优选实施例，其构造成附接到手动工具壳体的鼻部。附件在壳体中具有可连接到手动工具的输出轴的旋转传动系，驱动系驱动具有外部凸轮槽的筒形凸轮。凸轮从动件骑在凸轮槽中并产生往复运动，凸轮从动件是凸轮从动件组件的一部分，工具保持器附接到凸轮随动组件。优选实施例具有凸轮槽构造，其使得工具保持件在切削冲程期间移动较慢并且在返回冲程期间更快地移动，从而趋向于优化切割工具的操作。优选实施例还包括行星齿轮组，用于降低手动工具输出轴的转速，以降低附件的往复运动速度。

摘要： An anti-jam assembly for incorporation in an article destroying appliance includes a fixed core mount assembly including a first support member spaced apart from a second support member. At least one moveable cutter shaft is disposed between and rotatably mounted to the first and second support members. A third elongate member extends in parallel relationship to the at least one cutter shaft. This third support member is moveable from a first position to at least a second position. The first and the at least second position correspond to a variable width of a feed path directing an article toward the at least one cutter. An arm is affixed to the elongate member and pivotal at a mounting surface when the elongate member moves toward the second position. A sensor activates when it detects movement of the arm. The arm and the sensor are removed from a proximity of the at least one cutter or the feed path.
