Incline disc variable target size sawguides for circular gang saws

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.
