ABSTRACT:
The power saw is provided with a shoe pivotally mounted on a post which is mounted in a cavity of the nose section of the gear case of the saw. The post has a multiplicity of grooves separated by lands which are flat between the grooves. A lock pin is mounted in the nose section transverse and spaced from the post. When the pin is in its normal locking position, the round exterior of the pin engages one of the grooves on the post to retain the post and shoe in position relative to the saw. The lock pin has a flat section which is parallel to and spaced from the flats on the post when the pin is rotated to the release position freeing the post and shoe for movement to adjust the position relative to the saw. A lever is mounted on the end of the pin which projects through the side of the gear case. The inside of the lever has a dimple which engages the soft boot covering the gear case. This develops enough friction to hold the lever in its normal position until manually actuated to release position allowing adjustment of the shoe position.
