SAWMILL.

Specification of Letters Patent.

Patented March 3, 1908.

1 Application filed March 6, 1907. Serial No. 360,861.

T 0 all whom it may concern:

Be it known that I, DANIEL I. KEOUGH, a citizen of the United States, residing at Lewis Run, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Sawmills, of which the'following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in saw mills, and pertains more particularly to what are known as drag saws.

The object of my invention is to provide a saw mill of this character, in which all parts are permanently mounted in a portable frame, and at the same time producing a durable, simple and effective mill of the char acter described.

In the accompanying drawings, Figure 1, is a perspective view of my improved saw mill. Fig. 2, is a side elevation looking from the opposite side from that shown in Fig. 1. Fig. 3, is a top plan view. Fig. 4, is a perspective view of a section of the saw carrying member and the saw attaching means.

Referring now to the drawings, 1 represents an elongated rectangular frame which is composed of heavy timbers to support the entire working part of the mill, so as to make the mill easily transportable so as not to disturb any of the working parts of the mill. This frame 1 may be constructed of any desired manner, but the timbers are preferably mortised together to form a more solid frame. The said frame is composed of the two bottom horizontal beams 2 and 3, and the upper horizontal beams 4 and 5 connected by the vertical standards 6, and the transverse beam 7. Connecting the standard 6 directly above the beam 2 is a second horizontal beam 8 which forms a guide for the saw carriage, as will be hereinafter more fully described. Between the beams 5 and 8 intermediate their ends, is a brace 9. Within the frame and connected, to the transverse beams 7, are the vertical standards 9 and 10 which are connected at their lower ends with a beam 11 in a plane with the beam 2, and with a second beam 12, in a line with the beam 8, forming, as before stated, the guide-way for the saw carrying member. The upper transverse beam 7 is connected by a horizontal beam 13 while, the beams 3 and 4 are braced by the beam 14. The beams 3 and 4 adjacent the rear end is provided with a standard 15. ards 15 intermediate their ends are provided with journals 16 in which is mounted the transverse horizontal shaft 17 and carried by the said shaft intermediate the standards is a drum or pulley 18 which is driven by means of a belt 19 driven by the engine 20 which is mounted upon a frame 21 carried by the lower beams. preferably of the gasolene type, although any desired form of engine may be used, as this forms no part of the invention.

The shaft 17 extends inwardly beyond. the standard 15 and is-provided with a disk 22 rigidly keyed upon the shaft, and is provided with a wrist-pin 23, all of which will be hereinafter more fully explained.

Extending transversely of the frame and mounted upon the tudinal beams 5 and 13 is a shaft 24 which is mounted in journal bearings 25 carried by the beams. The said shaft carries a large drum 26 which is directly over the space between the beams 8 and 12. Between the beams 8 and 12 and 2 and 11 is an elongated vertically-arranged saw carrying member 27, each side of which is provided with a pair of rollers 28 and 29, the rollers 28 of a size to snugly fit between the beams 2 and 8, and the rollers 29 between the beams 11 and 12,

and whereby the, saw-carrying member is free to travel longitudinally and is supported by the rollers, and said rollers preventing themember from moving upwardly or down wardly.

The upper edge of the saw-carrying member adjacent each end is provided with eyes 30 and 31. Passing through the eye 31 is a horizontal bolt 32 carrying the nut 33, while the opposite end of the -bolt is provided with an eye 34. Secured to said eye 34 is a cable 35 which passes horizontally to the end of the frame and passes a pulley 36 mounted between the standards 6 and 9, and extends u ward over the drum26 and around the same. Tlie cable after making this wrap around the drum passes downwardly around the pulley 37 mounted between the standards 6 and 10, and is secured to the eye 30 carried by the oposite end of the saw-carrying member. By oscillating the shaft 26 the drum is oscillated, and through the medium of the cable 35 the saw-carrying member is caused to travel back and forth. By turning the nut 33 the bolt 32 is adjusted horizontally and the cable The said standupper face of the longi- The said engine is j plates 38 and 39, and

35 is tightened, and thus takes up any stretching of the cable. The saw-carrying member at the upper and lower edges have bolted or otherwise secured thereto, the

plates is the shank 40 o the saw 41, and said shank is removably clamped between these plates by the U-shaped clips 42 and 43 whereby the saw can be readily removed for sharpening or for introducing a new saw thereln.

The shaft 24 is provided with a drum 44.

Carried by the upper face of the-beams 5 and 13 are bearings 45 in which is mounted a 5? transverse horizontal shaft 46, and mounted on said shaft intermediate its ends is a lever 47 the inner end of which carries a segment 48. Wound upon said drum 44 is a cable 49' which has its ends crossed and extending over the segment, and extending inwardly,

and the ends of said cable extend outwardly and are connected to eyes 50 carried by the outer ends of'the lever 47. Connected to the extreme outer ends of the lever is a pitman 2 5" 51 which has its lower end connected to the wrist pin 23.

In order to give the proper feed to the saw, as it will be seen that the saw or its connections have no vertical movement, I provide means for adjusting the entire frame, whereby, as the saw cuts through the log, the frame is lower and gives to the sawthe proper feed. To accomplish this result I provide the end of the frame with feet 52 on which the said frame is rocked. Adjacent the said feet the frame 1 is provided with a transverse bolt 53, the ends of which extend beyond the side beams of the frame, and pivotally carried by the said projecting end of the bolt on each side of the frame is a beam 54 and 55 which extend outwardly beyond the opposite end of the frame, and u on which the log to be sawed is placed. eyondthe log, or at the outer end of the beams is an upwardly-extending frame 56 which is rigidly connected to the beams, and thus held in a vertical position. Secured to the upper end of the said frame is a pulley 57, and over said pulley a cable 58 passes, one

end extending to aposition close to the the cable the frame-carrying the saw is raised, and thus can be lowered to give the proper feed to the saw as it cuts its way through the logs.

In order to keep the belt 19 at the proper 60" tension I provide a pivoted frame or belt tightener 60. This belt tightener is formed of a rectangular heavy frame which is pivoted between the two upper horizontal beams of the frame 1 directly over the engine, and

'65 the lower end thereof extends obliquely assing between said downwardly and is provided with a roller or drum 61 which rests upon the belt and gives the saw, as I will now proceed to describe.

In: operation, the engine is started, the belt 19 rotates the shaft 17, and the disk 22, by

1 means of the wrist-pin 14, causes the pi-tma-n 51 to move the lever 47 up and down, oscillating the segmental member 48 which, through the medium of the cable 49, oscillates the drum 44 carried by the shaft 24. The drum 26 being carried by said shaft necessarily oscillates therewith, and the cable 35 being wound upon the said drum 26, and said cable passing around the pulleys 36 and 37 at the end of the frame, and connected to the saw-carrying member, the same will be reciprocated back and forth to cause the saw 100 reciprocate, and thus properly saw the ogs.
