artnr IMPROVEMENT IN SAWING-IVIA'CHINES.

Specification forming part oi' Leiters Patent No. $001, dated May 30, 18H5.

To all whom t may concern,.-

.Be it known that we, A. E. VARNER and I. V. NVARNER, of Norwalk, in the county of Huron and State of Ohio, have invented certain new and useful Improvements in Sawing-Machines; and we do hereby declare that the following is a full and complete description of th'e constructionand operation of the same, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figure l is a plan view ot the'inachine. Fig. 2 isa side elevation. Fig.W 3 is an end view. Fig. 4 is a sectional View.

Like letters of reference denote like parts in the ,several views.

The nature of our invention relates to the inode of operating a circular and crosse-ut saw by the same gearing or horsepower, and

to the mode of holding the log in place while being sawed, also, to the manner of guiding, raising, and lowering the saw and holding it in place.

A represents the general form of the fra-me of the machine, which can be of any suitable construction adapted to the operating parts;

B is the driving-gear that works in a pinion, Z1, on the gear-wheel C. This gear-wheel turns the iiy-wheel D by means of a pinion, c, on its shaft.

d is a beveled gear on the ily-wheel, and forms a part of it, in which a beveled-gear wheel, E, on the end of the shaft E, works. To the other end of this shaft is connected a `wheel, H, that operates a circular saw, J, by

means ofthe belt li, in the ordinary manner. The wheel H is turned by the revolution of the wheel D, turning the shaft E by the beveled gears E and d. The crosscut-saw F is operated by `means of a connecting-rod, G, (seen in Fig. 1,) that is attached to the iiywheel l) at one end, the other end being jointed to the pitmen F of the saw.

f f is the cross-head secured to the pitmen, and moves on the guides J J in the ordinary way, insuring a straight vibrating motion of the saw. j

Between the inclined standards a of the .frame there is a slide, I, (represented in Figs. 3 and 4.1,) the side edges of which fit in grooves in the standards, that keep it in place as it is moved up or down. Through an opening in this slide (seen in Fig. gt) the pitinen of thel saw pass, by which it is supported in its in clined position. To the slide I is secured a catch, I', that rests on notches on one side of a spring, L, as represented, by which the slide through a guide, k, in the front standards, c',

that slides in grooves in the standards. The saw-guide m, by means of the arm m, is pivoted or hung to the back standards, a.

n is a spring that presses on the arm m of the guide.

p p are clamp-levers, resting on the log R, that pass through slots or guides i i in the front of the frame, and are adjusted and held in any desired position by means of the ratchets j on the standards a., in which the back ends of the levers catch.

R is a frame supporting the log, one end or cross-piece, T, of which can be raised or lowered by a rope, t, or its equivalent, attached to it and connecting it to a lever, V, which passes through a guide, u, in a standard, fu', and is secured in any position by a ratchet or rack, Z. The adjustable support T and clamplevers p, together with the rest of the supporting-frame, hold the log firmly in place while it is being sawed, and the saw is adjusted in relation to the log by means of the slide I, as before described. The horse-power is connected to the driving-shaft B, which revolves the gear-wheels, turning the fly-wheel D, that operates the circular saw, by means of the beveled gearing d and E, shaft P', and wheel H, as before stated. At the same time, by means of the connecting-rod G, the crosscut-saw is vibrated. Thus both saws are operated simultaneously by the same power.

Ve are aware that different saws have been operated by the same horse-power. Therefore we do not broadly claim thedJeombination of a horse-power with two sawsfoperated difbehind, (seen ferently; but We believe our arrangement of l crosscut and circula-r saws, when operated subthetwo saws and ofthe devices connectedthere-A stantially in the manner and for the purposes with is new andof our own invention. Thereset forth.

fore We confine our claim to the peculiar con- 4 struction and arrangement above described. Having thus fully described our invention, what We claim, and desire to secure by Letv\.itnesses: ters Patent of the UnitedStates, is- R. T. RUST, The above-described arrangement oi' the XV. L. HARROD.
