Abstract: 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.

Abstract: A power actuated miter saw has an adjustable rotatable mounting with respect to an elongated work holder so that the saw can be set in any one of a number of angular positions for the cut. The saw is lowered by a forward facing handle adjacent to which is a circular scale showing the angle. Mutually rotating parts have a 360.degree. bearing ring between them near the perimeter to provide abundant stability and also seal the movable members to keep them free of dust. A sawdust discharge travels with the saw blade to collect and discharge sawdust generated by the operation in a direction away from the operator. The saw blade is guarded while at rest as well as during a cutting operation on the work.
