The panel saw apparatus includes a pair of laterally spaced H-beams are attached. A first pair of leg portions of one H-beam have slots adjacent its ends so that this H-beam can, by means of bolts passing through the slots, be adjusted into a parallel relationship with the other H-beam. The second pair of leg portions of each H-beam each have a groove formed therein so that a strip portion of a rail member can be press-fitted therein. The rail members have shoulders that bear against the second leg portions of the H-beam with which they are associated. A carriage has wheels complementally grooved with respect to angled surfaces on the rail members thereby constraining the carriage for reciprocal movement. The carriage includes a turntable mounted for rotation with respect to a plate and its circular opening. An electric motor is mounted on one side of the turntable and a saw mount on the other side; a flexible belt extends through a segmental opening in the plate. A pressure foot mechanism assists in holding a panel board in place. A brake mechanism is engageable with one of the leg portions belonging to one of the H-beams.
Panel saw apparatus comprising a generally upright frame, vertical track means including a pair of laterally spaced H-beams, each having a first pair of oppositely directed leg portions secured to said frame and a pair of second oppositely directed leg portions spaced forwardly of said frame, said vertical track means also including a rail member mounted on each of said second leg portions, a carriage including upper and lower pairs of wheels engaging the rail members on each of said beams so that said carriage is constrained for reciprocable movement in a generally vertical plane forwardly of said beams, said carriage including a plate having a circular opening therein, a turntable mounted for rotation relative to said circular opening and forming a segmental opening relative to an arcuate edge of said circular opening, an electric motor supported on one side of said turntable and said motor having a shaft projecting therefrom, a drive pulley on said motor shaft in alignment with said segmental opening, a saw mount supported on the other side of said turntable and said saw mounted having a shaft projecting therefrom, a driven pulley on one end of said saw mount shaft in alignment with said segmental opening and also in alignment with said drive pulley, the other end of said saw mount shaft being adapted for the attachment of a circular saw blade thereto, and a flexible belt entrained about said pulleys and extending through said segmental opening.
Panel saw apparatus comprising a frame, track means including a pair of generally vertical beams, each having an H-shaped cross section formed with a web portion and first and second oppositely directed leg portions residing in generally parallel planes, means attaching said first leg portions to said frame, oppositely issuing rail members attached to each beam having V-shaped angled surfaces, each of said leg portions having a groove formed therein and each of said attaching means having a portion press-fitted into one of said grooved leg portions, carriage means, and two pairs of vertically and laterally spaced wheels on said carriage means, said wheels being formed with grooves having V-shaped angled surfaces for engaging said V-shaped angled surfaces on said rail members.
