Abstract: A cutting tool such as a tile saw is pivotally connected to a linear guide rod with a four-bar linkage. The linkage allows the cutting tool to be raised and lowered over a work table to facilitate plunge cutting. One link of the four-bar linkage is mounted over the linear guide rod in a fixed perpendicular relationship with the surface of the work table to ensure that the blade of the cutting tool is maintained in a similar perpendicular orientation throughout plunge cutting. This is achieved by adjusting the links of the four-bar linkage as a parallelogram linkage. A linear bearing is fitted between the fixed perpendicular link and the guide rod to allow the cutting tool and linkage to freely slide along an accurate linear cutting path.

Abstract: A carriage on the frame of a lumber edger is driven on tracks longitudinally from one limit to another. Two motors are arranged with their corresponding output shafts coaxial and facing each other. A saw blade is mounted to each shaft. The motors are mounted to laterally extending tracks on the carriage and actuators are provided for shifting the motors, and hence, the parallel saw blades toward and away from each other so that when the saws are translated longitudinally they will rip the irregular edges from a board. A chain conveyor runs through the machine frame and transports the boards to a position under the saws with the length of the boards directed longitudinally. When a rough board arrives under the saws the lines along which the saws will cut are marked on the board with parallel laser light beams. The saws are shifted laterally until the light lines are just inside of both rough edges.

Abstract: A board saw exhibits a frame on which a guide beam is horizontally slidable. A sawing unit is mounted with vertical mobility on the guide beam and is connected by a cable to a compensating weight.

Workpiece clamps, mounted on a workpiece guide, coact with a web length stop to insure cutting webs of equal length and initiate the substantially automatic reciprocation and indexing of the saw acting on the workpiece.

Abstract: Apparatus for guiding a power saw has a guide bar provided with side and end edges. Saw-guiding members near each side edge of the guide bar are parallel to the longitudinal axis of the bar and extend between opposite ends of the bar. There is a longitudinal slot at one end of the bar midway between the saw-guiding members and a cross bar at the opposite end. A clamp may be used to releasably attach the cross bar end of the guide bar to the workpiece while the opposite end is secured by a pivot member entered into the workpiece through the longitudinal slot. The power saw is fitted with a slide connector capable of slidably engaging either one of the saw-guiding members. The arrangement is such that a lengthly workpiece can be cut more than halfway through starting from one end edge whereupon the guide bar can be swung about the pivot to the opposite end edge which allows the cut to be completed with speed and accuracy.
