Abstract: A folding step assembly adapted for attachment to a vehicle with a base having an outwardly extending peripheral flange where the assembly can be attached to the bumper, for example in the area where a license plate is normally held. A first step is hingably connected to a lower edge portion of the base by a hinge device and adapted to be tilted between an extended horizontal position and a stored vertical position against the flange of the supporting plate. A bias device such as a spring is fitted around the hinge pin to bias the first step to a normally vertical position generally parallel to the supporting plate with the step abutting the flange.

Abstract: A circular saw retaining arrangement where a circular saw blade is retained on a driven arbor shaft including an arbor plate located a selected distance from the end of the arbor and where the shaft of the arbor between the arbor plate and the end of the arbor shaft is threaded to receive an arbor nut, an improved means of securing the saw blade to the arbor including a collar of selected peripheral configuration to receive wrench means wherein the collar has a central aperture to receive the arbor shaft wherein one surface of the collar is roughened and adapted to be urged against the saw blade with the arbor nut threaded on the arbor shaft and tightened against the side of the collar opposite the side bearing the roughened surface.
