Filed:

Oct 3, 1975

Appl. No.:

5/619216

Inventors:

Robert Joseph May - New York NY

International Classification:

A63H 3304

US Classification:

35 69

Abstract:

Movie-Cubes is a system by which all the surfaces of a group of three-dimensional cubes are patterned in a way that when the cubes are arranged and moved correctly, they create a continuous picture or pattern that changes and eventually returns to itself. The pattern is laid out on a 45. degree. zig-zag graph before it is applied to the cubes. When this group of patterned cubes is arranged, so that the picture or pattern matches from cube to cube, and alternating rows of matched cubes are moved correctly, they create a picture or pattern that not only changes, but eventually returns to where it started. This system operates on the principle of geometric progression whereby, once the group of cubes is matched correctly, they are moved and rotated in alternating rows from one side of the group of cubes to the opposite side. With each rotation and movement of a row of matched cubes, a new part of the picture or pattern is exposed until the picture or pattern eventually returns to its starting point.

Assignee:

CircSaw Technologies LLC - Pacific Palisades CA

International Classification:

B27B 5/29
B27B 9/04

Abstract:

An attachable rolling plate assembly which is attached as a single unit to a portable cutting tool to facilitate the safe rolling movement of the portable cutting tool on a workpiece. The invention comprises a frame assembly formed from a single piece of molded material such as fiber enriched high-impact nylon having a pair of oppositely disposed longitudinal sidewalls and a flat base portion having an opening through which a saw blade of a power saw extends. The invention also includes a cutting guide assembly to facilitate a straight cut, reduce torsional rotation of the saw blade and reduce kickback of the saw. A water spray hose is retained to spray water in front of a saw blade of a retained worm drive power saw.
