摘要:
The invention is a method for operating a panel saw of a framework supporting a set of beveled railings, the railings being held in a parallel and spaced apart orientation to one another and to the framework; a carriage having at least two pairs of opposing beveled carriage side edges and at least one tool securing apparatus, one pair of opposing carriage side edges reversibly removably engages the set of railings to movably locate the carriage between the set of railings; wherein the carriage moves in and out of contact with the railings through the top ends of the railings to allow the one pair of carriage side edges to be moved out of contact with the set of railings while alternately allowing the remaining pair to reversibly engage the set of railings in a manner that lets permits the carriage move along the railings in a self-centering manner.

The present invention relates to a guide rail assembly for securement of a tube cutting apparatus for cutting of boiler tube walls to a fixed point on a tube wall, while allowing lateral repositioning of a cutting tool relative to the tube wall. The assembly includes a guide rail having a convex surface along which a carriage having a cutting device may be fixedly positioned by mating friction engagement of a concave surface of pairs of linear guide blocks secured to the carriage with the convex surface of the guide rail.

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.

In a mechanism for cutting panels, including an approximately vertically standing backing structure for the panels to be cut and a lower panel edge support to define a work area through which a saw mounted on a carrier may be moved, the panels may be secured in their working position and moved into and out of the work area by means of a cantilever arm mounted on the backing structure outside the work area for pivotal movement, whereby a gripping device on the free end of the arm is moved into and out of the work area.
