Abstract: A sawguide positioning method for circular gang saws mounted on a single saw arbor shaft. A guide bar is positioned generally parallel to the saw arbor shaft. A plurality of sawguide pairs are slidably mounted on the guide bar for longitudinal axial travel thereon. The guides extend on either side of each of the circular saws. A pair of opposed sawguide positioning wedges are threadably mounted on a selectively rotatable shaft having a right hand threaded end and a left hand threaded end, the axis of the shaft being generally at right angles to both the saw arbor shaft and the guide bar. The wedges are threaded on to the selectively rotatable shaft with their vertices innermost. The threaded shaft has an enlarged diameter portion or disk intermediate the threaded ends which is rotatably positioned within matching recesses in the opposed faces of the sawguides. Selective rotation in either direction of the shaft causes axial travel of the positioning wedges along the shaft toward or away from the disk thereby repositioning the sawguides and changing the spacing between the saw blades. Confinement of the disk on the shaft within the mating recesses prohibits any longitudinal translation of the shaft relative to the sawguides thereby maintaining the opposed sawguide positioning wedges equidistant from the center of the shaft and thereby permitting the positioning wedges to operate in unison. Once adjusted, the sawguides are squeezed together thereby maintaining accurate saw positioning.

Abstract: A first collar is releasably slidably journalled onto a selectively rotatable shaft so as to lie in a first plane generally perpendicular to the shaft. The first collar has a first helically inclined cam surface extending between a thin portion of the first collar and a thick portion of the first collar. A second collar is releasably mountable onto the shaft into fixed relation relative to the shaft, so as to lie in a second plane generally parallel to the first plane. The second collar has a cam follower surface such as a second helical inclined cam surface for sliding engagement over the first helically inclined cam surface between the thick portion and the thick portion of the first collar upon selective rotation of the shaft. First and second sawguides are slidably mounted on the shaft for longitudinal sliding thereon on opposed sides of the first and second collars. The first sawguide has the first collar rigidly mountable thereto, the first collar being adjacent the second collar. The second sawguide is adjacent the second collar. A press is provided for urging the first and second sawguides slidably towards each other along the shaft against the first and second collars respectively. The longitudinal translation of the second collar along the shaft relative to the first collar causes relative longitudinal translation between the first and second sawguides on the shaft.
