Description:
"My said invention relates to that class of sawing-machines which are designed to saw siding or clapboards, or other thin stuff, from lumber which has previously been sawed in ordinary saw-mills, into pieces of proper size; and it consists in so pivoting or attaching the frame which contains the feed-bed and rollers to the permanent frame of the machine supporting the saw, that the lumber being sawed may be fed to the saw in such a position with reference to the saw as that the edges of the siding may be of different thicknesses, the saw passing through the pieces being resawed diagonally..."
