摘要： A scroll saw with an adjustable tensioning mechanism includes a housing having an inner surface and a pivoting arm having a rearward end disposed within an opening in the housing. A first blade clamp is disposed at the forward end of the pivoting arm and secures the upper end of a saw blade. The lower end of the saw blade is secured in a second blade clamp disposed at the forward end of a lower arm. A wedge is disposed within the housing, in contact with the inner surface of the housing. The wedge also is disposed in contact with and translatable along a surface of the pivoting arm. A rod is linked to the wedge at one end and extends through the pivoting arm. The rod includes an upwardly turned arm. A cam having a spiral track is rotatably mounted at the front of the pivoting arm with the upwardly turned arm disposed in the track. Rotation of the cam causes the track to move along the upwardly turned arm, further causing the rod and wedge to move forwardly, with the contact between the wedge and the inner surface causing the wedge and the rearward end of the pivoting arm to pivot downwardly, and the forward end of the pivoting arm to pivot upwardly to increase the tension of the blade.

摘要： An improved portable wood planing machine for the surface planing of wooden planks or boards is provided. The machine has a switched reluctance motor. In an exemplary embodiment, the planing machine includes a carriage assembly locking mechanism for locking the carriage assembly relative to a plurality of vertical support columns to thereby vertically fix the carriage assembly. In one form, the carriage assembly locking mechanism includes a plurality of levers which cooperate to engage the support columns of the carriage assembly. The exemplary embodiment further includes a depth stop adjustment mechanism which allows the operator to accurately select a minimum workpiece depth from one or more predetermined depths and a material removal indicator assembly operable for enabling the user of the planing machine to accurately determine the amount of material to be removed during each pass of the workpiece.

摘要： A table saw or other cutting machine includes carrying members on an underside of the work table generally adjacent the flanged table edge in order to provide an increased gripping surface area to be grasped by the operator when lifting and transporting the cutting machine. The machine is preferably equipped with invertible extension support assemblies for supporting a workpiece extending horizontally beyond the work table. Such support assemblies include support members slidably extendable horizontally on rods toward and away from the work table. A dust deflection skirt extends from a lower surface of the work table into the generally hollow dust-receiving cavity portion of a dust shroud located within the saw's enclosed base. This skirt deflects dust or chips into the interior of the hollow dust-receiving cavity. Anti-kickback spacers are preferably sealed-end blind rivets mounted on the anti-kickback pawls at intermediate locations thereon. Such spacers slidably maintain the anti-kickback pawls in a generally parallel relationship with the kerf splitter plate. Also hardened portions of the throat plate keep it from being damaged by serrated edges of the anti-kickback pawls and to prevent binding when the blade is lowered.

摘要翻译： 台锯或其他切割机包括在工作台的下侧的承载构件，其大致与凸缘台边缘相邻，以便在提升和运送切割机时提供由操作者掌握的增加的抓握表面面积。 机器优选地配备有用于支撑水平地延伸到工作台的工件的可逆延伸支撑组件。 这种支撑组件包括支撑构件，其可在棒上朝向和离开工作台水平地可滑动地延伸。 灰尘偏转裙从工作台的下表面延伸到位于锯的封闭底座内的防尘罩的大致中空的灰尘接收腔部分。 该裙部将灰尘或碎屑偏转到中空灰尘接收腔的内部。 防反冲隔离物优选是在其上的中间位置处安装在防反冲爪上的密封端盲铆钉。 这样的间隔件将防反冲爪与切割分离板大致平行的关系滑动地保持。 喉板的硬化部分也防止其被反扣爪的锯齿形边缘损坏，并且当刀片降低时防止粘合。
