Abstract
A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.
Claims18
A method of operating a saw, wherein the saw comprises a saw house with an interior and an access opening to the interior, the method comprising:
- stopping a cutting operation of at least one circular saw blade, the at least one circular saw blade being in the interior of the saw house, the stopping of the cutting operation including stopping rotation of the at least one circular saw blade, and the stopping of the cutting operation further including stopping orbital movement of an arm of the saw within the interior of the saw house;
- moving the at least one circular saw blade to a known position in the interior of the saw house;
- and
- moving at least one blade cover for the at least one circular saw blade from an exposing position in which the at least one blade cover is spaced from the at least one circular saw blade to allow the at least one circular saw blade to rotate and the arm of the saw to orbitally move within the interior of the saw house for cutting an object within the interior of the saw house to a covering position in which the at least one blade cover at least partially covers a cutting edge of the at least one circular saw blade with the at least one circular saw blade in the known position, wherein the at least one blade cover is mounted to a structure of the saw house within the interior of the saw house such that the at least one blade cover remains stationary when in the exposing position while the at least one circular saw blade is translated within the interior of the saw house during the cutting operation, the at least one blade cover has a face panel and an edge portion extending from the face panel, and in moving the at least one blade cover to the covering position with the at least one circular saw blade in the known position, the face panel is moved adjacent to a face of the at least one circular saw blade and the edge portion is moved adjacent to at least a portion of the cutting edge of the at least one circular saw blade.
A method of operating a saw, wherein the saw comprises a saw house with an interior and an access opening to the interior, the method comprising:
- disabling the saw from a cutting operation in the interior of the saw house by:
- (i) stopping rotation of a circular saw blade within the interior of the saw house, and (ii) stopping orbital movement of an arm of the saw within the interior of the saw house;
- moving the circular saw blade to a known position in the interior of the saw house;
- and
- moving a blade cover for the circular saw blade from an exposing position in which the blade cover is sufficiently spaced from the circular saw blade to allow the circular saw blade to rotate and the arm of the saw to orbitally move within the interior of the saw house for cutting an object within the interior of the saw house to a covering position in which the blade cover at least partially covers a cutting edge of the circular saw blade with the circular saw blade in the known position, wherein the blade cover is mounted to a structure of the saw house within the interior of the saw house such that the blade cover remains stationary when in the exposing position while the circular saw blade is translated within the interior of saw house during the cutting operation, the blade cover has a face panel and an edge portion extending from the face panel, and in moving the blade cover to the covering position with the circular saw blade in the known position, the face panel is moved adjacent to a face of the circular saw blade and the edge portion is moved adjacent to at least a portion of the cutting edge of the circular saw blade.
