INCLINE WEDGE VARIABLE TARGET SIZE SAWGUIDES FOR CIRCULAR GANG SAWS

摘要

The device for selectively actuable positioning of sawguides for circular gang sawsmounted on a saw arbor shaft comprises a first shaft such as a guide bar extending along a firstaxis generally parallel to the saw arbor shaft, first and second sawguides slidably mounted on thefirst shaft for longitudinal sliding thereon on opposed sides of first and second wedges mountedin threaded engagement, in left and right hand threaded engagement respectively, on a selectivelyrotatable second shaft extending between the first and second sawguides along a second axisgenerally perpendicular to the first axis, threadably journalled in the first and second wedges androtatably centered and anchored between the first and second sawguides, the first and secondwedges threadably mounted on the second shaft in opposed facing relation with the vertices of thefirst and second wedges closest to a center position centered along the second shaft, means forselectively rotating the second shaft so as to, when selectively rotated in a first direction, force thefirst and second wedges towards the center position, and when selectively rotated in a seconddirection counter to the first direction so as to force the first and second wedges away from thecenter position, an actuator urges the first and second sawguides slidably towards each other alongthe first shaft against the first and second wedges, respectively, whereby translation of the first andsecond wedges along the second shaft by reason of selective rotation of the second shaft causesrelative longitudinal translation between the first and second sawguides on the first shaft.
