Portable saws
First Claim
1. In a portable saw including a baseplate, a cased motor having a circular saw blade connected thereto and driven thereby, said motor being mounted pivotally relative to said baseplate so that a cutting extension of the saw blade below said base plate is variable according to a desired depth of cutting, and wherein an upstanding guide means is provided on top of a worktable as a guide for traverse cutting of a workpiece, the improvement comprising an elongate member connected to said baseplate to act as guide in the movement of said baseplate across said worktable by abutment against said guide means, said elongate member is pivotally connected to the baseplate and adjustable in its angle relative thereto so as to vary the angle of the baseplate, and hence of the saw blade relative to the direction of travel and desired direction of cut thereby to permit production of a width of cut greater than the width of the saw blade.

Abstract
The saw comprises a cased motor driving a circular saw blade that is pivotally mounted to a baseplate to vary the cutting extension below the baseplate. A channel-shaped part that is of smaller cross-section than an open slot in the baseplate is used for guiding the baseplate during a cutting operation over a worktable by abutment against or location over an upstanding guide located on the worktable. The channel-shaped part is medially pivoted to the baseplate and its angle thereto is adjusted by way of a cam so as to vary the angle of the baseplate, and hence of the saw blade, relative to the direction of travel, thereby to permit the production of a width of cut greater than the width of the saw blade.
