PORTABLE SAW-MILL.

SPECIFICATION forming part of Letters Patent No. 296,220, dated April l, 1884. l

Application filed December 8,1883. (No model.)

ib all whom it may concern.-

Beit known that I, `WILLIAM C. Ronenns, a citizen of the United States, residing at Owlet Green, in the county of Van Zandt and 5 State of Texas, have invented certain ner and useful Improvements in Portable Saw-Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

The object of this improvement is 'to produce a portable saw-mill of such cheap and economical plan as can be built and repaired in almost any locality.

rIhe invention consists in the peculiar construction and arrangement of the parts, as Will be hereinafter fully explained and specically claimed, reference being had to the drawings herewith filed as part hereof, and in which similar letters of reference denote like parts.

Figure lis a side elevation, partly in section. Fig. 2 is an end elevation with some of the parts removed and some in section, to bet` ter illustrate the construction. Fig. 3 repre sents some of the details partly in section.

A is the track-frame of the mill, which is to be mounted at both ends on transporting# Wheels B.

C is an upright post or beam bolted tothe fra-me A, and provided at its upper end with a rectangular projection or bracket, S, which may be aiiixed to post Gby mortise and tenen, as shown at R, or in any secure manner. To the bracket S are alixed journal-boxes,which form' bearings for. trunnions la of the vibrating box K, which actsas an arbor for the guide-bar I, having eyes at its lower end, to which the upper end of the saw G is affixed by bolts g. Below the track-frame A, and located centrally therewith, are perpendicular beams o", tenoned to the t1'aclr-fran1eA, and braced in position by the angled beams c', tenoned to the frame Aand to the perpendicular piece a, and further secured in position by cast iron plates N, which embrace the joints so formed, and are made fast thereto by Wood-screws n. A pair of double `iianged castings, D and D', connected by integra-l lugs 5o d, are secured in a Vertical position to the perpendicular beams a by the screws dnear their lower ends, and to the frame A by flanged metal plates and Wood-screws, as shown at b. A counterpart of the double-flanged 5 5 casting D is bolted thereto by means of perforated lugs corresponding to the lugs, as shown at d. The double-ilanged castings D D, thus uni-ted, forni an arbor, as shown in Fig. 2, for the cross-head E, to which the lower end of 6o the saWGis secured. Pendent from the cross- 'head E are plate-links F, to which the pitman l? is connected with the saw, thence with the crank H on the shaft M, which is operated by pulley J, to be connected by the usual 6 5 belt with drivingpower. The frame should be elevated sufcicntly to clear the machinery both for transportation and operation. The carriage V, for feeding the log T to the saw, is stopped While the log is hoisted to the 7o carriage by means of skids connected with the side ofthe frame A. The log is 'fed to the saw automatically by the usual appliance, which is not shown, as no claims are to be made in such regard.

'Ihe motion of the drivingshaft M will give action to the saw G, which, by reason of the guide-bar I and vibrating box Ii, will vibrate to and from the dotted line, as shown in Fig. l, and clear the cut going and resume it on the 8o downstroke.

Having thus explained the construction and operation 0f my improvement, what I claim as new, and desire to secure by Letters Patent, is as follows: l S5 l. In a reciprocating saw mill, the vibrating box K and guide-bar I, operating therein, in combination with. the saur G, cross-head E, having pendent links F, for connecting with driving-shaft through pitman l? and crank H, 9o and the cross-head arbor formed of the plates D D', all constructed and arranged to operate substantially as specified.

2. The mounted frame A, provided with upright beam C and proj ecton S, perpendcu- In testimony whereof I affix my signature in lar beams a, brace-beams a', and embracingpresence of two Witnesses. plates N, in combination with the vibrating box K, gude-bar I, saw G, cross-head E, WILLIAMCRITTINGTON RODGERS. having pendent links F, and the cross-head arbor D D, ptman P, and driving-shaft M, Vtnesses:

substantially as specified, for the purpose set R. S. JONES,
