ABSTRACT:
This invention relates to radial cams and tools utilizing radial cams. The radial cam includes a flat plate having at least a first flat surface and a spiral groove therein having a spiral track formed of a plurality of tracks having progressively smaller radii and including an outermost track, innermost track and intermediate tracks therebetween. A return slot connects the innermost track to the outermost track whereby a continuous groove is formed. A device utilizing this cam includes a base, the above described cam pivotally mounted to the base, a cam follower slidably received in the continuous groove and a at least one lever arm pivotally attached to the cam follower and the base.
