1,440,386	Jan. 02, 1923	Polishing and Grinding Machine	Charlie L. Hawes	Ashtabula, OH	Abstract: The object of the presently invention is to provide a polishing or grinding machine of the dual opposed wheel type, which will be capable of automatically operating on articles such as axes, hatchets, and 'the like. For operation on articles of this character, the grinding or polishing wheels require, to be more or less closely positioned as different portions of the article are presented.

In the case of an ax or hatchet, the two surfaces of the article are symmetrical, and the adjustment of the two wheels accordingly is in unison but in opposite direction. This, however, ,need not necessarily be the case, and furthermore, by an adaptation, articles of circular cross-section, such as certain forms of hammerheads, for example, which constitute frustra of cones or pyramids, may be ground with equal facility.
