EMPRQVEMENT IN SAWING=MACHINES.

Specification describing a new and Improved Sawing, Planing, and Boring-Machine, in vented by WILLIAM WEAVER, of Greenwich, in the county of lVashington and State of New York.

Figure 1, Sheet 1, is a top view of my improved machine. Fig. 2, Sheet 1, is a side View of the same looking in the direction of arrow 1, Fig. 1. Fig. 3, Sheet 2, is an end view of the same looking in the direction of arrow 2, Fig. 1. Fig. 4, Sheet 2, is a side view of the same looking in the direction of arrow 3, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved machine which shall be simple in construction, inexpensive in manufacture, con venient in use, and effective in operation, and which shall be so constructed that it may be readily adjusted for use as a scroll-saw, a circular saw, a planer, or a boring-machine, and which shall be convenient and effective in either capacity 5 and it consists in the construction and combination of the various parts of the machine, as hereinafter more fully described.

A is the frame-work of the machine. B is the driving-pulley or drum, the journals of which revolve in bearings attached to the frame A, the outer journal projecting sufficiently to receive a crank, G, or band-pulley, either or both, so that the machine may be driven by hand or power, as may be desired. 1) are belts, two or more of which should be used, which pass around the driving-pulley or drum B and around the loose pulley or pulleys E. The opposite sides of the belts l) are drawn inward and passed around the shaft F upon opposite sides of said shaft alternately, as shown in Figs. 1 and 2, makin g the strain upon said shaft equal in opposite directions, and thus relieving the said shatt from any side strain from the said belts. The loose pulleys E, when more than one are used, are placed upon a shaft attached to the upper ends of the two levers H, which are pivoted to the frame A or to brackets or suppports attached to the said frame. When only one pulley, E, is used it is pivoted to and between two centers, Gr, secured to the ends of the levers H by screw-threads or otherwise, so that they may be set up to compensate for wear. The other ends of the levers H are rigidly connected by a cross-bar, to which is attached one end of a strap, I, for adjusting the tension of the belts D and taking up the stretch of said belts. The free end of the strap I passes through a slotted support, J, to which is pivoted a levercam, K, so that the strap I can be securely and firmly held when adjusted. The shaft F revolves in bearings attached to the frame A,

and to its outer end is secured a fly-wheel, L,

to which is attached a crank-pin, N, on which is pivoted the upper end of a connecting-rod, N, the lower end of which is pivoted to the crank 0 formed upon the end of the rocksha-it P, which works in bearings attached to the lower part of the frame A, the crank 0 bein g made of such a length that the revolution of the crank fly-wheel L will only rock the shaft P. To the rock-shaft P is rigidly attached a crank-arm, Q, to the outer end of which is pivoted the lower end of the connecting-rod It, the upper end of which is pivoted to the sliding block S, which slides in ways secured to the frame A. T is the scroll-saw, the lower end of which is secured to the sliding block S by a spring-key, a pin, or other conveniently-detachable device. The upper end of the saw T is secured by a similar device to the sliding block U, which works in ways attached to the downwardly-projecting end of the arm V, which is curved, as shown in Fig. 3, and the other end of which projects downward and is secured to the frame A. To the upper partof the sliding block U is attached a hook or knob, to which is secured the end of a strap, W, which passes over the pulley X, and its other end is attached to a screw or other catch on the said pulley X. With the pulley X or with the journal of said pulley is rigidly connected at smaller pulley, V, to which is attached a screw or other catch to receive the end of the strap Z, which passes over the said pulley V. and to the other end of which is attached one end of a coiled spring, A, the other end of which is adjustably connected to the end of a bent arm, B, the other end of which is attached to the arm or support V.

B y this construction the saw T is drawn downward by the downward movement of the cran karm Q of the rock-shaft P, which movement of the saw T expands the coiled spring A. As the crank-arm Q again rises the contraction of the coiled spring A raises the saw T for another stroke.

To the shaft F is attached a circular saw, 0, in the ordinary manner. To the shaft F is also attached a cutter-head, D, the cutters of which may be plain for ordinary planing,

' or may be notched or scalloped to form moldings, &c. Upon the end of the shaft F is screwed a nut, E, having a socket formed in its outer end to receive a boring-tool, F. G is the table of the machine, which rests upon the top of the frame A, and is slotted for the passage of the scroll-saw T and the circular saw C. The table G is secured and hinged at one end to the frame A by hooks and staples or eyes H. To the other end of the table G is attached the upper end of the strap or plate 1, which is slotted longitudinally to receive a bolt, J, attached to the frame A, and upon which is screwed a handnut, K, so that the end of the table G may be conveniently raised or lowered to adj ustit with reference to the circular saw 0, as the character of the workmay require. The table G is provided with an adjustable gauge or guide, L, in the ordinary manner. M is a table attached to upon their outer ends, so that the table M may be secured at any desired elevation, according to the character of the work to be done.

\Vhen either the circular-saw, the planer, or the boring-tool is to be used, the other two of said parts are to be detached, so as to ob tain as much space as possible for the work, avoid carrying unnecessary weight, and avoid the danger of injuring the workman with the tools not being used. When either the circular-saw, the planer, or the boring-tool is to be used, the upper end of the connecting-rod N should be detached from the crank-pin N of the fly-wheel L, to avoid driving the mechanism that operates the scroll-saw. When the scroll-saw is to be used the other tools should all be detached from the shaft F.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- The combination of the crank fly-wheel L, pin N, connecting-rod N, crank O, rock-shaft P, crank Q, connecting-rod R, slide S, curved arm V, slide U, strap WV, pulley V, strap Z, and spring A with the shaft F, two or more driving-belts, D, driving-pulley B, loose pulley E (one or more,)levers H, strap I, and camclamp J K, substantiall as herein shown and described, and for the purpose set forth.

WILLIAM WEAVER.
