Abstract: A mounting device for mounting non-contacting distance sensors to a variable-height implement of a paver or other construction vehicle is disclosed. The mounting device includes two extension arm assemblies, each extension arm assembly having an inner section and an outer section that are movable relative to each other, with the inner section being mounted to the variable-height implement. The mounting device further includes a beam assembly attached to the outer sections of the extension arm assemblies. The beam assembly includes a beam and mounting brackets for attaching a plurality of non-contacting distance sensors to the beam.

Abstract: A saw fence having an elongate fence member, a lock-back attached to an end of the fence member for engaging a side rail of a saw table, a base member attached to an opposite end of the fence member and adapted to engage a side rail of a saw table. The base member includes a housing having a transverse channel to receive a side rail of a saw table, a hook member pivotally attached to the base member having a tongue portion which extends downwardly and inwardly from the base member, and a bolt threaded into the base member for pivotally displacing the hook member inwardly to engage a side rail in a locked position, or outwardly to disengage a side rail in a release position.

Abstract: A workpiece support system for a power tool, preferably a multipurpose woodworking tool of the type having a frame, a main table mounted on the frame, and a power-driven tool member associated with the main table. The support system comprises a first pair of tubular rails attached to longitudinal sides of the main table, a pair of extension rods telescoping within the rails, an auxiliary table having a second pair of rails attached thereto which telescope over and are supported by the protruding portions of the rods. The support system includes capstan screws for releasably locking the extension rods to the pairs of rails. The system may include at least one secondary table mounted on the frame and having a third pair of rails telescoping over ends of the protruding portions and including similar locking means. Another embodiment includes a side frame for supporting long workpieces.

Abstract: A multipurpose woodworking tool of the type having a frame, a pair of parallel way tubes extending longitudinally of the frame, and a headstock mounted on the way tubes in which the improvement comprises a pair of yokes joining the way tubes together at ends thereof, pairs of upright members at the ends of the frame and spaced apart to receive one of the yokes therebetween, and an apparatus extending between the yokes and the upright members which enables the way tubes to be changed in elevation between a lower elevation optimal for utilizing a table saw attachment mounted on the way tubes and a higher elevation optimal for utilizing a lathe attachment. In one embodiment, the apparatus includes spring-loaded pins which are sidewardly displaceable from the yokes, and holes positioned at at least two elevations on the upright members to be engaged by the pins.
