Description:

This is a continuation-in-part of the application that became patent 3,998,121.

"A motor operated power saw is mounted on a table by employment of a tiltable platform so that the saw is lowered to cutting position by manually depressing a handle. Surrounding the upper half of the saw blade is a composite guard consisting of a main guard and a movable nose guard which, when the blade is in elevated non-operating condition, cover the exposed portion of the blade. The main guard is pivotally mounted on the tiltable platform and is provided with a cam follower which, upon engagement with a cam track on the table, automatically elevates the main guard and accompanying nose guard as the blade is advanced through a cutting operation."
