smaller. And in some cases the said spinner is suppressed, by fixing to the top of this cone at a one of its drawing systems, receiving motion from a fixed pinion, which serves at the same time as a collar for this end of the cone to move in. Or in fine, if a fired pinion should give too much drawing tendency (as was before observed), then with a proper wheel a motion of its own is given to that pinion, differing from that of the cone and drawing system, that the effect may be as desired. In witness whereof, &c. Specification of the Patent granted to WILLIAM NEWBERRY, of St. John Street, in the County of Middlesex, Gentleman; for an Invention of certain Machinery for the Purpose of sawing Wood, splitting or paring Skins, and various other useful Purposes. Dated January 30, 1808. With a Plate. To all to whom these presents shall come, &c. Now KNOW YE, that in compliance with the said proviso, I the said William Newberry do hereby declare, that my said invention is described and ascertained in and by the drawings hereunto annexed, and the following description thereof; that is to say: First, my invention consists of a method of working an endless revolving saw-blade over two dumb wheels or rollers, to be used for any of the purposes to which a common saw may applied; to this sort of saw a variety of machinery may be attached for guiding the pieces to be cut, for the manner of doing which the annexed drawing will give an explanation. be Fig. 1 32 Patent for sawing Wood, splitting or paring Skins, &c. Fig. 1, (Plate III.) A, is a cast-iron frame to carry the wheels. B B are the wheels, having each an iron plate screwed behind it, to prevent the saw from running off backward. C C is the blade of the saw. D is a bench or platform on which the piece to be cut is laid. E E are two semicircles of iron fixed thereto, whose centres are parallel to that part of the saw-blade which is even with the top of the bench; one of these is marked with the divisions of a circle, by which means on turning them in the sliders, the bench may be placed at any angle to the blade of the saw, and there fixed by means of the screws F. Gis a guide to keep the saw from running out of its line; close under the bench is ano ther guide like it. HH are two wedges to force down the lower wheel, so as to give the saw the necessary tension. I is the piece to be cut, which may be brought forward to the saw either by hand or by passing it be tween rollers in the well-known way now practised for drawing iron, &c. therefore, on carrying the wheels to revolve by any moving power, the saw continually passes through the piece till it is cut. Fig. 2, are guides for cutting parallel pieces from any kind of planks or boards. A, is a part of the bench; and B, of the saw. C is a slider, having in the end of it any number of small rollers parallel to the saw; this slide moves in and out at pleasure, and is fixed by a thumbscrew. D is a roller fixed to a universal joint, and pressed in by the springs EE; therefore upon C being fixed at any distance from the saw, the roller D pressing the piece close against C, a parallel piece is taken off throughout, however the plank may be warped or twisted; if the bench is elevated so as to cause the rollers in C to form an angle with the saw, a feather-edged piece is taken |
