ABSTRACT:
An oscillating blade saw used for cutting a wide range of construction materials, vehicular materials, and general structural materials. The saw is inherently safer than prior art cutting tools such as circular saws, jig saws, band saws, and the like, while being effective in cutting many materials that are cut by prior art power saws. The oscillating blade saw of the present invention comprises an electrical motor coupled to one end of a drive shaft, the motor being powered by either AC utility power or self-contained, rechargeable batteries. An output shaft is mounted in the distal end of the tool, and includes a cam follower impinging on a cam mounted on the drive shaft. The cam and follower are dimensioned so that the output shaft oscillates through an angular excursion of a few degrees or less. A disc-like saw blade is mounted on the output shaft, the blade having non-direction saw teeth extending from the edge thereof. The blade may be circular, trianguloid, ellipsoid, or the like, depending upon the nature and purpose of the cut to be made. The blade disc may be hardened to cut dense and tough materials. The tool may be fashioned as a hand-held device, with a tubular neck extending from the motor housing to enclose the drive shaft and provide a handle for grasping, or may comprise a table saw, or a radial arm saw. Alternatively, the output shaft and cam assembly may be driven through a flexible cable shaft by a stationary motor to provide enhanced maneuverability and flexibility in use.
