IMPROVEMENT IN WOOD-SAWING MACHINES.

Specilication forming part of Letters Patent No. 135,216, dated January 28, 1873.

To all whom it may concern.-

Be it known that I, SAMUEL FUNCK, of Quincy, Illinois, have made and invented a new and useful Improvement in Wood-Sawin g Machines, of which the following is a specitication:

N alture and Objects of the Invention..

My invention has relation to an improved machine for sawing wood; and consists ot' an open frame, at the top ot' one side ot' which, attached to two uprights, is secured a horizontal beam, below which the sawing apparatus is placed. An ordinary saw is fastened in any convenient manner at either end to metallic slides that work in grooves attached to the two upright pieces of a frame, the top piece of which is horizontal. To the lower ends of the `vertical pieces last-aforesaid rollers are secured, upon which the saw-frame rests-two or more guide-rods on either side, which pass through the adjacent uprights of the principal frame, assisting in holding it in place as well as in giving it, when in motion, a true direction.

To the slides to which the ends of the saw are fastened either` end of a metallic rod is attached, which, bent in rectangular form, extends upward above the top of the saw-frame. At its corners cords are fastened, which are secured to a windlass, by means of which the saw-frame may be elevated. Securely fastened to the rear side of the saw-frame is a pivot, upon which a pitman works that, connected with gearings and a crank, actuates the sawing mechanism.

Description of the Accompanying Drawing.

General Description.

that passes through the uprights c a and top piece a. C is the saw, which is of the usual crosscut form, either end of which is secured to the bolts D that pass throughA the ears E upon theI slides F. The slides F are'constructed so as to admit of their being raised or lowered within the vertical beds G, which are fastenedto theupright pieces, their sides being carried beyond the edges of the slide to prevent it from being dislocated. (See Fig. l.) Ri gidl y fixed in the saw-frame are the horizontal guide-rods'H, which pass through the up- I'ights a a, and are made of suiiicient length to permit the necessary movement ofthe sawfra1ne.\ ,Turning within slots cut in the verticalpieces of the saw-frame are the rollers I, upon which the frame rests, and which serve to facilitate its operation. At a convenient point upon the rear side of the horizontal piece b the pivot or piu K is attached, and working upon it is one end of the pitmaii L, the other end of which turns upon the pivot or pin M uponthe wheel N, which is rigidly secured to the axle O. A gear-wheel, P, at a point upon the axle O toward the rear, is operated by a gear-wheel, R, upon the axle S that is provided with a crank, T, being placed in a convenient position to eiect its purposes. Upon the horizontal top piece a a windlass, V, which is ot' the usual form, is placed, the crank U exten ding toward the rear, two grooves being cut in that portion which extends beyond the front of the frame. vCords U are fastened so as to roll in either of the grooves, passing over rollers attached to the piece A, as shown in Fig. 2. The cords U are fastened to the rod V, which is attached to the slides F, being bent upward in a rectangular or other convenient form. A pin, W, may be used to hold the crank U in place, a .hole being cut to receive it.

Operation.

The wood to be'sawed being placed in position below the saw, the crank T is turned, when motion is communicated to the sawframe, moving it from side to side; it being desired to raise the saw, thel crank U is turned, when it is drawn upward'at pleasure. The pin W being applied, the saw remains suspended.

' Claim.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

The saw-frame B, consisting of two vertical In testimony that l claim the foregoing improvement in machines for sawing wood, as above described, I have hereunto set my hand and one horizontal pieces, provided with the and seal this 5th day of October, 1872. guide-rods H, rollers I, vertical slide-beds G,

and pivot K, in combination with the pitman L, wheel N, axle O, and gear-wheels P and R, Witnesses: when arranged and operated substantially as L. E. EMMONS,
