Patent number: 6389864Abstract: A sheet bending brake and stabilizing assembly wherein the sheet bending brake alone is constructed and arranged such that when a workpiece is clamped for bending when a person stands on the floor facing the handle means and the handle means is grasped and raised in a direction away from the person in order to move the handle means and raise the handles means, forces occur which prevent the handle means from moving sufficiently to produce a predetermined bend and the forces causes the entire sheet bending brake to tip away from the person about the portions of the legs which project outwardly from said bending brake and thus prevent the movement of the bending member relative to the first member and prevent bending of the workpiece. The stabilizing assembly for counteracting such forces on the sheet bending brake comprises transversely spaced rails receiving at least a portion of the ends of the leg assemblies.Type: GrantFiled: February 4, 2000Date of Patent: May 21, 2002Assignee: Tapco International CorporationInventors: Arthur B.

Patent number: 5899132Abstract: 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.Type: GrantFiled: June 7, 1995Date of Patent: May 4, 1999Assignee: Tapco Products Company, Inc.Inventors: Douglas G.
