Abstract: A power saw having one or more features for facilitating straight line and/or angled cuts, including (1) at least two sets of non-slip wheels connected to the bottom plate, each set of wheels comprising an axle having at least two wheels that are fixed to rotate at the same rate as the axle, (2) a transparent guide attached to and extending from the front of the bottom plate comprising a straight line marking aligned with the saw blade for alignment with a marking on the workpiece, and (3) a sliding guide adapted to travel within a slot in the bottom plate, the sliding guide adjustable to a desired angle relative to the saw blade and attached to a mechanism that provides resistance to rearward movement of the sliding guide and retracts the sliding guide back to a starting position after completion of a cut.

Abstract: A saw having a body, a continuous loop cutting chain, and a chain support extending from the body, the body comprising one or more handles, a motor, and a chain driver. The chain support comprises one or more chain support bars having one or more wheels mounted thereon, each wheel adapted to receive and guide a portion of the chain, at least one wheel of which is mounted at an end of the one or more support bars. The chain support may be pivotable to a desired angle within a range of angles relative to the body. An adjustable guide mechanism may enable setting a maximum distance that the saw blade is able to protrude through a workpiece.
