Abstract: A fire grate for holding particulate carbonaceous fuel such as sawdust and powdered coal consisting of stepped horizontally disposed and vertically spaced concentric grate members having center openings and defining a pyramidal structure. The grate is enclosed by the fuel which, by virtue of the stepped arrangement of the concentric grate members, is prevented from freely falling through the spaces between adjacent grate members.

Abstract: The present invention relates to a washing machine and more particularly to a portable, peripheral oscillating agitation dual purpose washing machine. It is capable of cleaning out dirt materials from fabrics and dinner wares. It comprises a cylindrical enclosure including roller means as a base for portability, an inner cylinder acting as a washing chamber or tub where materials to be washed are deposited, an agitator peripherally disposed inside the tub which oscillates by means of a linkage connected to a worm and wormgear means powered preferably by an electric motor installed underneath. As the agitator rotatively oscillates the water and soap solution is propelled towards the center at a certain speed and direction opposite that of the materials to be washed thereby achieving a very efficient washing process.
