To wHoM 1i MAY` ooNesRN:

Beit known that I, Pres LEE SHEPLERof Whitehouse, in the county of.Lucas, and State of Ohio, have invented a new and useful Improvement in sawing-Machines; and I do dee-lare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference ,markedthereom and being a part of this specification. l i y Figure 1 is ya. plan view of my apparatus. l e v v Figure 2 is a. perspective view of the method of communicating motion.

Figure 3 is a side elevation of the saw-guide, andfdog, and rest; also, showing drums.

'Ihe same letters indicate like parts in each figure.

The nature of this invention is to adapt any kind of power that may be desired, to driving circular saws and drag-saws, in such n. manner thatboth'may be used at the same time,or either separately, as required.

In order to accomplish this end, I construct a suitable freine, A, to sustain the working parts of the apparatus. Upon this frame A is secured the frame B, upon which runs, in suitable boxes, C, the driving-shaft D, to the outer end of which any desired power may be attached.

E is a bevel-gear, rigidly attached to this shaft, and engages with bevel-gear F, also rigidly attached to shaft G, and gives moti'n thereto. i t

I-I is a gear-wheel, also rigidly attached to the shaft D, and engages with the pinion-I, and gives motion to the shaft J', which runs in suitable boxes, K, attached to the bearings L, placed upon the frame B. V

The pinion I-is loosely sleeved upon thc shaft J', and should be attached to the band-wheel M, which, in turnyshould be attached to-the half of the clutch-N, so that all would form biit one piece in effect, and all loosely sleeved upon the shaft J. V.

The other k half of the clutch, O, is rigidly attached'to the shaft J, at the outer end of' which should be attached the' fly-wheel P. v i A Q is a crotched lever, intended to be used to engage and diseng'age the `two halves, N and O, of'the clutch.

The pitman R is connccted'by a. proper wrist-pin to fly-wheel P, and, at its opposite end, to the cross-head S, which has a reciprocating motion between the ways T, supported upon proper bearings.

U is an arm, .one end of which is attached to the cross-head' S, while the other is secured to the drag-saw V, which passes between, and is held in place by the vertical guides W.

X is :L lever, fulcrumcd to vthe vertical guides W, its outer end being provided with a dog, Y, which is slotted, so that while assisting to hold the leg being operated upon,.it will also, by means'of thc slot, guide and steady the outer end of the drag-saw.

Z is a rest, pivotcd to the carriage-frame A, and. provided with a slot, B, within .which works the arm of the curved lever C", and by meansrof which the end of the logmay be elevated ordcpressed at pleasure.

The shaft G is provided with al sleeve, D", operated in its forward or backward movement by the lever E,

and forms one-half of a clutch, the other half, F, of which is rigidly secured to thc shaft G", running in proper boxes, II, upon the carriage-frame A. Upon this latter shaft is rigidly fastened the spool I, around which winds the chain or rope J, the other end of which is attached to the carriage K, which is constructed in the usuel manner, andiprovidcd with dogs, L, 'by means of which the log is held in place.

Upon either side ofl the spool I, and upon the same" shaft, arc loosely sleeved the drums M, which will revolve independently of'each other,y and upon which the log rests. By means ofthese drums, I am able to draw baekithe carriage without moving tho log, as, the drums being sleeved, the shaft and spool areallowcd to revolve without giving motion- `to the drum'. i- 4 By means of a band-wheel, M, and a suitable belt, motion may be given to a circular saw when desired.

What I claim as inyinvention, and desire to secure by Letters Patent, is- 4 l. Theoombination of the drums l shaft G", spocl I, chain J", and carriage K, all arranged to operate as herein described and shown. i y

2. The rest Z, when provided with a slot, B", and operated by means of the eurvedand bent lever C, all as and for the purpose described and shown. A i
