Abstract: A folding, straight-line, workpiece guide for a saw having a base, a saw blade extending vertically through the base, and a feed path relative to the saw blade. The workpiece guide comprises an elongated table which can be collapsed into a folded configuration or set up and locked into a working configuration. A carriage is constructed and arranged to support multiple elongated workpieces and to slide along the foldable table. The foldable table has multiple chassis sections pivotally connected to one another, adjustable legs, connectors for connecting the table to the base of the saw parallel to the feed path of the saw, and a guide track for guiding the carriage along the table when the table is in the working configuration.

Abstract: An apparatus for precision linear positioning of material along a frame, having carrier means for carrying the material juxtaposed above the frame, means for linearly moving the carrier means along the frame having a plurality of pneumatic cylinders each having an extendable and rectractable piston, the cylinders connected to each other in a series and including a first end pneumatic cylinder attached to the frame and a last end pneumatic cylinder attached to the carrier means, such that the carrier means is moved by the amount of the cumulative extension and retraction of the pistons, stopping means associated with each the pneumatic cylinder for limiting the extension of each the piston, and means for providing a controllable amount of air to each pneumatic cylinder to selectively control extension and retraction of each piston.

Abstract: Apparatus for piercing an arcuate workpiece includes a frame, an index table rotatably mounted on the frame, piercing means horizontally adjustable on the frame with respect to the index table and a punch head movable horizontally into engagement with the workpiece mounted to the index table. A swivel clamping mechanism detachably mounts the workpiece to the index table.

Abstract: A setworks in which a series of additively connected cylinder drives functions to locate a knee means for a desired cut on a log. A setworks in which a vernier adjusting mechanism precisely locates the knee means, which is held in position by an independent stopping means, and wherein while the knee means is so held the vernier mechanism is reset for subsequent full range operation.
