' 1: Schedule refund to in these LottexrPatent and making pan of the same.

Figurel of .the drawings is a sectional view. of my wood-sswing machine, and

' Figurc2 is a detail.

(lily invention has relation to devices for sawing wood, an

It consists mainly in providing andarranging more eflicient and perfect meansfor that purpose than have heretofore been invented.

'To this end, I construct a frame, in a quadrangular form, with an upright post at each corner, all united by end and side-bars, as shown on the drawings.

0n the top of these comer-posts, respectively,.I adi just grooved caps, marked A-von the drawings, adapted to hold and regulate the movements of the saw-rfiame, hereinafter mentioned;

The letter B is the'saw-fi'ame, adj usted in the grooves of the.caps.A, and which is moved back and forth by the devices hereinafter specified.

A second frame, 0, is attached to the main name, in the manner shown on fig. 1, extending forward from the front of the main frame, and serves as a restand support for'the wheels, journals, and cranks, next described.

The letter D represents a large cogged wheel, the cogs of which are attached to its innersides, and point downward, as shown.

This wheel is connected with a side-arm of the frame 0 by a short journal working therein, and constitutes. the driving-wheel of my device, and which maybe operated by a crank on its side, or abelt on its periphery.

The letter E is a pinion, attached to the end of the shaft a. It has cogs on its periphery, working with. the cogs on the wheel D.

The shaft a extends inward to a point a little less than midway between the side-arms of the frame 0, where it is united with the craniefi A shaft, corresponding in lengthen-11d size with the shaft a, reaches from the opposite side of the crank G beyond the opposite 'side of the frame 0, where it is secured to and operates a fly-wheel of the usual .construction. I

The-journals. upon-which these shafts rotate'are placed on the tops of the side-arms of frame 0.

The letter 0 is a pitman, connecting the crank G with the saw-frame B, in the manner shown.

The letter at is a shaft, adjusted in arms extending rearward from the front posts of the main frame, so arranged that it may rotate partly around therein, the object of which is I to support and aid in the movements of the saw-horse, next mentioned.

The saw-horse is marked Hon-the drawings, and it is arranged in such manner that the wood may be forced upward to thesaws, instead of remaining stationary, as is usual in'such devices.

The wood is forced upward to the saw by lifting the horse uponv which it'rests.

The letter L represents abent lever, firmly attached to the horse, in the manner shown, and extending for ward of the frame 0. t

This lever is connected with. the shaft d, as shown, by a ring and staple, or other suitable device, and the V- shaped extension of the saw-horse is also connected with said shaft, in the manner represented on fig. 2.

When thewood to be sawed is in place, a book, 8,

- hinged to the saw-horse, is thrown over the same, and

holds it securely in theerotch of the saw-horse.

It will readily be seen that any desirable number of saws may be adjusted in the saw-frame, but I usually "place two only therein, at such distance from each other as may be requiredto saw the wood of the desired length.

The operator raises the wood to the saw by press ing down upon the extreme end of the lever L.

What I claim as myinvention, and desire to secure by. Letters Patent, is.

A sawing-machine, for wood, having main frame and frame 0, as described, grooved caps A, saw-frame B, wheels D and E, shafts e and d, crank G, pitman c, lever -L, saw-horse H, and hook s, when each part is constructed, arranged, and operates as described.

In testimony that I claim theabove, I have hereunto suhscribed my name, in the presence of two witnesses.
