*Mw- IMPROVEMENT IN'sAwrNG-M'ACHINE,

'The Schedule referred toLin these Letters Patent and making part of the same.

To all whom it may concern:

, Be it known that I, J AMES ANTnoNY Enscron, of

Elston Station, in the county of Gole and State of Missouri, `have invented a new and .improved Sawin'g-Machine; `and I do vhereby declare that the following is` aiull, clear, and exact description thereof, which will enable others skilled in'the art to make and use the same, vreference `being 4had to the accompanying drawing forming part of this specification, in which; 4 Figure 1 represents a side -elevatiompartly in section, of my improved sawing-machine". i

Figure 2 is a plan or top view oi' the same. l .Figure 3 is a detail side view, on, an enlarged scale,

` of the adjustable leg attachment.A

Similailetters of reference indicate corresponding parts'.

This. invention' relates to a new sewing-machine, which is so constructed that itcan saw 'horizontally 'as well as vertically through trees or logs of suitable thickness, and which `can be adjusted to saw at any suitable height, and in any desired position. l

A in the drawing represents a wheel or circular frame, which is by'means of four, more or less, legs B B, supported in a horizontal position.

The 'legs B are, by pins a, pivoted to ears b, that project from the under side of thewheel, and can, for transportation, be folded against the wheel, to

.enable the same to be rolled on edge'over the ground.

`The edge of 'each ear b, or the upper end of each leg B, is made in form of a` notchedv segment, into which lis locked a pin, c, for retaining 'each leg at a suitable degree of inclination. Thereby the frame A can he secured at a suitable height.

To the 4center of the frameA is, by`a pin, d, pivoted a long slotted frame, O, which serves as a guide for the slide D, for operating the saw I}.`

The slide D is, by a rod, e, connected with a crankshaft, F, that is 'hung iu the back end. of the frameO.

r Byrevolving the crank-shaft F, the slide will receive reciprocating motion, together with the saw that is attached to the same.

For vertical sawing, I pivot to the back part of the' slide D a' bow-shaped fra-ine, G, which, at its f1ont.eml, earries a cross-bar, j,sliding in a forked pin, y, that is put in'to the front end ofthe slide.

The saw Ais attachedv to this frameG, andv will, by the weight of or by means of an additional weight,fH, on the same, be fed down through the block. In this 4position the frame O is locked by means of an up right post, I, which prevents it from being -swung on the pivot d.

For horizontal sawing, i. e., for cuttingoi trees, 86e., I remove the frame G- and post I, and (secure thev saw E directly into the front end of the slide D, as shown in' iig. 2, which will bring the saw into a horizontal position. l then, after having secured `the legs B Afirmly to the ground, swing the frame C l against-a spring, J, on A,'eompressing said spring.

The saw is operated by means of the crank-shaft,

.and fed by the spring J.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent-` 1. The wheel A, for supporting the sawing-machine, provided wit-h pivoted legs, which are locked to notched segments vby pins c, to be adjustable .as described. Y i

2. 'lhe wheel A, and slotted guide-frame 0, pivoted together, as set forth, combined with a slide, kD, and spring J, all relatively arranged for sawing the erect timber, as shown in` fig. 2 of drawing. l

3.V 'lhe subject-matter ot' the second clause, combined with the weighted frame fGr H, as shown in ir.` 1 of drawing.

4. The perforated adjustable post I, combined with the adjustable legs B, as andfor the purpose described.

' The above speciiication of my invention signed by me this 3d day of May, 1870. A JAMES ANTHONY ELSTON.
