Specification of Letters Patent. Application filed August 25, 1908. Serial 1%. 450,236.

Patented March 1c, 1909.

Tov all whom it may concern:

Be it known that I, WILLIAM S. OVERLIN, a citizen of the United States, residing at Fulton, in the county of Multnomah and State of Oregon, have invented a new and useful Sawin -Machine, of which the following is a spec cation.

My invention relates to sawing machines in which the saw is attached to a reciprocating sliding head. I The sliding head is caused to reciprocate, between 'de's, back and forth by a connecting ro the -connecting rod being so attached to the sliding head that the saw does not move across the log in a horizontal plane, but oscillates, thus clearing the cut from sawdust which greatly facilitates the operation of the saw.. The saw will also feed into the cut made as fast as desired. It is also arranged so that if the tumedinto the desired log to be sawed should not touch the ground at the place to be sawed, the entire machine may be fastened to the log without further support. I attain these objects by the mechanisms illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the entire machine, showing it in position on the log. Fig. 2 isa to elevation of the mechanism. Fig. 3 is an e arged view of the sliding head illustrating the take-up for the shoes and the connecting arm that causes the saw to oscillate. Fig. 4 is the top elevation of the same.

Similar numerals refer to similar parts throughout the several views. I

1 is the base which is fastened to the frame and upon which the power generator is placed. 4

2 is that part of the frame to which the base 1 is attached. .3 is a remaining part of the frame. Connecting frame 2 with frame 3 is a swivel 'oin. 4 which is rigidly fastened to 2. 3 slides within 4. When position it may be held there by setscrew 5 which extends through tee8 to the outer end of which the guides 10 and 11 are fastened; this secures the frame of the machine to the guides for the sliding head. To the end of casting 9, which passes through tee 8, gear 12 is keyed.

15 is thebelt which delivers power from the generator to the pulley 14. Attached to 14 is a spur pinion 13 which meshes with 12. As 12 revolves the shaft to which it is keyed, or otherwise fastened, also revolves; this in turn causes crank 16 to rotate. Pitman 17 being secured to 16 and 18 causes the sliding head, to which the saw is attached, to oscillate two strokes. Connecting rod 17 is attached to 18 which is fastened to each side of, the sliding- head 22 and 23. Ann 20 is also fastened to 17 at '19.. The saw end of 20 is.

the driving end of 17 moves in circle, and

since it is held in place at 18, it may be seen that a-point 19 on arm 20 is caused to move up and down on an are about 26 as a center,

but since the saw is fastened to the other end of 20, a sim lar motion is transmitted to it. This is necessary for if the saw is drawn back and forth across the log in a horizontal plane the sawdust will be left in the lo Secured to cross bars 26 are adjustable s oes 24; as they wear they may be taken up by means of a slot 25. To hold the sawin alinement and to prevent wabbling, or buckling, a. guide 27 is used. a

28 is a saw and 30 are set screws to secure the-saw to the driving mechanism.

I am aware that prior to my invention sawing machines have been made, but I do claim the machine, as herewith illustrated, does contain new and useful mechanisms and I therefore claim;

1. A sawing machine comprising a frame,

' driving mechanism mounted thereon, a

guide, a driving head slidably mounted in the uide, a saw pivotally connected with said ead, a pitman pivoted to the head and having pivotal connection with the saw, and means connecting the pitman and driving mechanism.

2. A sawin machine comprising a'frame, driving mec anism thereon including a guide, a driving headslideble in the guide, saw arin for oscillating the saw as it is recipa saw, an arm connected rigidly at one end roceted by the head.

with the saw and pivotally connected between its ends to the driving head, and a pit- WILLIAM OVERLIN 5 man connected with the head for reciprocat- Witnesses:

ing the same and having pivotal connection R. B. GOODE,

' between its ends with the opposite end of the T. W. Enos.
