Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. This patent's specification has survived but the drawing is lost. For improvements in Saw Mills; Othniel Stone, Pittsford, Monroe county, New York, October 6. A saw is to be so made as to form a band, or hoop, of any convenient diameter and width; this band is to be passed, like a strap, over two circular drums, one above the other, and the sawing is to be effected by the straight part between the drums; these latter are to have projecting rims, to bear against the back of the saw. To prevent the saw from trembling, it is to pass between friction rollers, stationed just below and above the timber to be sawed. “The specific new and useful improvements here-in-before described, and claimed by me as the inventor, are the following. “First. The shape of the saw. Second. The manner of hanging the saw. Third. The manner of keeping the saw steady, when in motion, by means of rollers. Fourth. The manner of making the saw with teeth on one or both edges.” We have, on more than one occasion, had to refer to the article Sawing, in Rees' Cyclopedia, in which this saw is mentioned as having been patented in England, long ago; how frequently it has sought the same sanction with us, we shall not stop to inquire; but we know that it was patented in 1817 (#{X2,809}), by Adam Stewart, of Baltimore, Maryland; the practical difficulties, however, attending its construction and use, soon convinced its re-inventors that it was best to abandon it.
