The annexed engravings represent an im- provement made in machinery, named "the adju??table bevel gauging and indicating bench, for sawing bevelled work." It is the inven- tion of Alfred C. Cook, of Russelville, Ky., who has taken measures to secure a patent for it. Figure 1 is a perspective view of the ma- chine, and fig. 2 is an end view. The same letters refer to like parts. The nature of the improvement consists in an adU8tal;k hoY d gauging bench, having a travelling fe ed carriage on the top to feed in the lumber to the saw, so as to cut the stuff to any desired bevel, according to the way the frame is set and gauged. A circular saw is represented on the figures, but it is equally adapted to work with a reciprocating one. A is the main frame, which sustams the swinging bench ; B is the swinging adj ustable bench, it is secured upon and turns on a shaft, C, which extends the length of the frame, and is supported in posts, D D. This bench is attached by each of its ends, on one side, to standards, f?? E , by a pin, a, at each end, which serve as the fulcra for the bench to turn upon; these standards have slots, b b, for screws, d d, to raise or elevate them (the standards) and bench. These set screws, d 4 retain the standards at such an elevation at one side as will fix the position, inclined or horizontal, of the bench, for the stuff to be fed to the saw. I' F are segmeatal braces let into the two end pieces, / /, of bench B; each, curved brace, F, has a slot, g, cut in it for a set screw, h, to work in, as the bench, B, moves in a vertical circle. These braces keep the swinging bench firm and steady in its position when at work, G is a pointer hand se -cured on the end of shaft, C; it moves with said shaft, as the bench, B, is raised or lowered at one side, and points to the numerals and words on the index plate, H, to indicate the position of the gauging bevel bench; it points to the exact angle of the bench, and tells at once what bevel will be cut upon the stuff fed into the saw. I is the feed carriage; it slides on the top and is guided on the ways, k k, by the flange pieces, 11. These flange strips are adjustable by plates of metal, m m, which are secured transversely on the underside of the carriage, and to which the flanges are attached ; the set screws, n n, secure the plates, in m, as they work in slots in said plates. These flanges are made adjustable to allow the bench, B, to be set at the greatest possible angle to which it is capable ot being set. J2J" is the side rest, against which the stuff lays while being sawed; this rest is made adjustable by the set screws, q q, which work in slots : by the use of this rest, in connection with the adjustable bench, the " flare " and bevel of staves m;iy be cut at tlie same time, as tl;is rest can be set at any angle desired by the set screws, V,and by a pivot axis working ii: u slot urai the distant end of the riirriage. L is a heel rest or dog, for the end nf the board or stnil to rest against; it is attached to the side ol the rest and is adjustable by the set screw, r, in a slot. J'jlig. 1, and J, tig. 2, is a circular saw; it is secured on a horizontal shall. O, driven by any power, and works through .1 daring opening, K, in the bench and carriage. The shaft of the saw is supported in bearing standards, p p. From the description given of the engravings, our readers will have obtained a correct understanding of the nature, action, and use ot the adjustable bench, feed carriage, and their adjuncts, whereby stuff may be mitred and sawed to any bevel and angle, from 0 to 90 . The machine is equally adapted lor common straight slitting, and sawing work ot all kinds. The improvement can be applied to all saw frames, and the extra expense cannot be much; nothing at least in comparison to the advantages obtained. More information may be obtained by letter addressed to the inventor.
