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.

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： 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 sheet bending brake comprises a frame having a fixed jaw and a movable jaw. The fixed jaw defines a clamping surface and the movable jaw has a clamping surface movable between workpiece clamping and non-clamping positions relative to the clamping surface on the fixed jaw. A bending member is hingedly connected to the fixed jaw. A handle is pivoted to the frame. A plurality of axially extensible links are provided. Each link is pivoted at one end to the handle and at the other end to the movable jaw such that in one position of the handle, the links move the movable jaw out of clamping position, and in another position of the handle, the movable jaw is in clamping position. Each link includes an upper block connected to the frame, a shaft extending from the upper block and rotatable therein and threaded into a lower block pivoted to the movable jaw. The shaft has a socket connection in the upper end thereof accessible through an opening in the upper block.
