摘要： A portable saw table which comprises an elongated saw table and a saw track pivotally mounted therebetween for a rotation about an axis substantially perpendicular to a longitudinal axis of the table base. A saw slide mounted on the saw track and supports a portable saw. A support at each end of the saw table allows the portable saw table to be tilted relative to the supports about a second axis parallel to the axis of the table. A sector member is pivotally connected to the table base so that as the table base is tilted, the sector member is moved in a plane perpendicular to the axis of the saw table. The sector member provides stability and guides the table and saw track. Thus, the table base, saw track and sector member can be tilted relative to the supports while the saw track is allowed to pivot relative to the table base and the sector member. A locking device on the supports engages the sector member to lock the saw table in a tilted position. In another form, the portable saw table is mounted on supports and locked in selected adjusted positions. The saw track and saw slide are constructed to minimize lateral movement of the saw slide.

摘要翻译： 一种便携式锯台，其包括细长锯床和在其间枢转地安装的锯轨，用于围绕基本上垂直于台座的纵向轴线的轴线旋转。 安装在锯轨上的锯条，并支撑便携式锯。 在锯台的每一端处的支撑件允许便携式锯床相对于支撑件相对于平行于工作台的轴线的第二轴线倾斜。 扇形构件枢转地连接到台架基座，使得当桌台倾斜时，扇形构件在垂直于锯台的轴线的平面中移动。 扇形构件提供稳定性并引导台面和锯轨。 因此，台架基座，锯轨道和扇形构件可以相对于支撑件倾斜，同时允许锯轨相对于台座和扇形构件枢转。 支撑件上的锁定装置接合扇形构件以将锯台锁定在倾斜位置。 在另一种形式中，便携式锯床安装在支撑件上并锁定在选定的调整位置。 锯轨和锯条的构造是为了减少锯片的横向移动。

摘要： A portable saw table for a portable saw or router comprising a table base for supporting a workpiece, and a slide track support pivoted about a pivot axis to the table base. A slide is movable with respect to the support and slide tracks are mounted on the slide. A protractor is movable with the support and has indicia about the periphery thereof. An indicator on the table base is associated with the indicia of the protractor. The pivot axis and the protractor have common axis. A lock lever is pivoted on the protractor and a threaded shaft extends through the support and is threaded into the lock member for causing the lock lever to frictionally engage the table base and lock the support and slide in angularly adjusted position relative to the table base and longitudinally adjusted position relative to the support.

摘要： A portable saw table comprising a saw track pivotally supported on a saw table. An improved lightweight plastic protractor and indexer plate are rotatably mounted with respect to each other by an improved pivot mount. The pivot mount comprises a plurality of lobes received in a complementary recess in the indexer plate in a spline-like engagement providing strength and rigidity to prevent flexing to ensure accurate pivotal movement. The improved protractor is guided by a gib mounted on the indexer plate for smooth pivotal movement. The plastic protractor includes indicia to indicate the degree of angular movement and the plastic indexer plate includes a window for viewing the indicia. In one form, the protractor has an angled portion with indicia and the indexer plate has an angled magnifying sight lens for easy viewing of the adjustment angle. A hollow material stop is provided to accommodate workpieces of varying thickness. U-brackets hold the saw shoe plate to the saw slide and a spring loaded saw stop prevents the saw slide from sliding past the ends of the saw tracks. Additionally, an adjustable leg assembly is provided for adjusting the height of the saw table and is removable therefrom.

摘要： A portable slitter for selectively roll slitting rib forming or perforating sheet metal workpieces and having a beam-type frame, a pair of spaced thin walled and light weight rotary torque tube roll shafts mounted in the frame and supporting the work rolls, and a plurality of pairs of opposed stabilizing support blocks disposed between the shafts and the associated frame beams and providing further strength to the shafts by functioning as intermediate span shaft journal supports carrying the roll work loads imposed on shafts directly into the frame beams. The bearing members can be readily removed and adjusted longitudinally of the shafts without taking the frame apart. The slitter can be readily manually transported to the work site because it has a high strength-to-weight ratio and is light in overall weight. The slitter has substantial operational strength and improved work roll registry and alignment under continuous and/or adverse on-site operating conditions.
