SAWING-MACHINE.

Patented June 15, 1909.

Application filed May 18, 1908. Serial No. 433,501.

To all whom it may concern:

Be it known that I, DANIEL I. KnoUcI-I, a citizen of the United States, residing at New Martinsville, in the county of \Vetzel and State of West Virginia, have invented certain new and useful Improvements in Sawing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in sawing machines.

The object of my invention is to provide a saw mill. mounted upon a light frame, and so constructed and arranged that it can readily be carried from place to place through the woods 'to saw each tree or log in its fallen position, and thus saving the moving or transplanting of the logs to the machine.

Another object of my invention is to provide a machine of this character which is more readily transportable, and which has certain details of structure which produce a more simple, cheap and effective sawing machine.

In the accompanying drawings, Figure 1, is a side elevation of my improved sawing maqhine. 1. Fig. 3, is a front end view of theme..- chine. Fig. 4, is an end enlarged side elevation of the manual operating means carried by the upper end of the frame for operating the saw. F ig.'5, is a side elevation of the saw-operating belt showing the connection of the wrist-pin therewith, and showing the 'pitman. Fig. 6, is an enlarged side elevation of the belt-tightening means, whereby the saw is stopped without stopping the engine. Fig. 7, is an enlarged perspective view of the pitman connection with the saw, and also showing the guide rollers carried by the saw for guiding the saw between the saw carriage. Fig. 8, is an enlarged end view of the saw guide showing the means of adjustment.

Referring now to the drawings, 1 represents a rectangular metal frame made of very light L-bars and riveted together in any desired manner, and while I will describe the specific form of frame and the specific means of bracing the same, it will be understood that any form of frame could be used withoutdeparting from my invention. The frame consists of the bottom, horizontal bars 2 connected to the vertical corner bars 3. These corner bars are connected at their Fig. 2, is a top plan view of Fig.

side. The vertical corner bars 3 are connected together at their upper and lowed ends,

by the transverse bars 5 and 6, the whole frame being riveted together and provided with necessary. braces, as shown at 7 and 8. One side of the frame intermediate the top bar 4 and botom bar 2, is provided with an L-bar 9 which extends the entire length of the frame, and extends a considerable distance beyond the frame, as indicated at 10, whereby it forms one'side of the saw guide. Connecting the

bars

9 and 2 is a vertical bar 11 which forms a stop or marks the rearward movement of the saw carriage, all of which will be hereinafter more fully described- Secured to the vertical bar 11 and spaced a distance from the bar 9, is a second bar 12 which extends forwardly beyond the end of the frame to the outer end of the extension 10 of the bar 9, and the same being spaced apart a distance to allow the saw to pass between the same. The lower beam 2 likewise extends beyond the end of the frame. Connected to the lower end of the vertical bars 11 is a horizonta1 bar 13 which extends out to the end of the bar 10.

The outer ends of the bars 10 and 12 are turned outwardly, as indicated at 14 and 15, and to which are riveted the plates 1 1 and 15. Connecting the'upper end thereof is a plate 16 which hasone cnd'riveted to the plate 14, While the op osite end of the plate is provided with s ots 17 through which the bolts 18 pass, said bolts being secured to the late 15 by means of the slot,

and thus it .Wlll be seen that the bars 10 and 12 forming the saw-guide can be adjusted to or from each other, providing for saws of different thicknesses.

The forward end of the frame 1 is provided with a vertical bar 19 to which is fastened the transverse bar 20. -The outer end of the bar is fastened to the corner post 3, and is turned downwardly, as indicated at 21, and secured by bolts or rivets 22 to this downwardly-turned portion 21 are the braces 23 and 24. which are of a form to conform with the bars or rails 10 and 12, and thus support and brace said bars inter: mediate their ends, as clearly shown in Fig. 1.

Extending longitudinally of the frame, and secured to the lower end bars 6, are two parallel bars 25 and 26. The bars are L- shaped, and'are of light material, the same as the remainder of the frame, forthe purpose of making a light machine. Carried bythe forward end of the said bars 25 and 26 are journals 27. Mounted in said ournals is a shaft 28 which extends beyond the journals on each side. The pulley 29 is carried by one end of the shaft, .and in a horizontal plane with said pulley is a pulley 30 driven by the engine 31, and a belt 32 passes around said pulleys by means of which the shaft 28is rotated. Carried by the opposite end of the shaft 28 is a pulley 33 over which passes the belt 34, which drives the pitman. p

Mounted upon the bars 25 and 26 and longitudinally movable thereon, is a frame 35 which is held a ainst any vertical or lateral movement. Carried by the said frame are journals in which is mounted the shaft 36, the outer end of the shaft carryinga ulley 37 over which the belt 34 passes.

heinner end of the frame has an operating bar 38 pivoted at 39 to ears 40 carried by the frame, and whereb the same is nioved longitudinally upon t e bars 25 and 26. The outer end of the bar .38 is pivotally connected to the lever 41, the said lever pivoted at 42 to the frame 1, and by drawmg the lever 41 rearwardly the pulley 37 s moved and the belt tightened, so that it will be driven by the pulley 33, which is driven by the engine, as heretofore described. In

order to hold the lever in its adjusted position-I provide the bar 38 with teeth 43, and carried by the lever is a pivoted pawl 44 held by gravity or sprin in engagement with the teeth. Connecte to the pawl 44 is a rod 45 which extends upwardly and is connected to a pivoted lever 46 carried by the rear face of the operating lever 41. By the construction and arrangement of parts it will be seen that when the saw is running, and it is desired to instantly stop the same, all that is necessary is to shove your hand against the lever 46 and the belt 34 will be loosened, so that it, will cease to travel. The outer face of the belt is provided with a wrist-pin 47 which is secured to the belt by flatheaded bolts 48 which pass from the under side of the belt, and through the pin and having nuts thereon. This wrist-pin as shown, extends all the way across the belt, allowing for a greater securing means, which prevents any twisting thereof, and which. also revents 'ithe wrist-pin from twistin the belt and causes the belt to run smooth y. The wrist-pin also extends considerably beyond the edge of the belt, and has the pitman 48 connected thereto, and said pitman extends forwardly and is connected to the saw, as will be hereinafter more fully described.

Between the

beams

10 and 12 and 2 and 4,

is the saw 49 which is supported by the rollers. Carried by the opposite sides of the saw are plates 51 which are bolted thereto by bolts or otherwise secured thereto, and said plates are of a width less than the space between the two pairs of the guide rails,

whereby the plates will not engage the same.

Carried by the upper'and lower edges of the plates are the rollers52 arranged two at the upper edge and two at the lower edge, and arranged directly opposite on opposite sides of the saw. These rollers approximatelyat all times engage the upper and lower faces. I

of the rails, and support the saw in a hori- 'zontal position free to move between the bars, as clearly shown in the drawings. Se-' cured to the-inner plate 51 is an outwardly extending plate 53, and passing through the plate 53, the plates 51, and the saw 49 is the wrist-pin 54, to which the forward end of the pitman 48 is attached, and whereby the saw is reciprocated.

In order to operate the saw by hand, I provide the upper end of the frame with a transverse bar 55, and extending rearwardly from said bar 55 are two

bars

56 and 57 on which is mounted a transverse shaft 58. Said shaft between the bars 56 and. 57 is provided with a gear wheel 59. The shaft 58 extends out beyond the

bars

56 and 57, and at one end is provided the pulley 60 which is in a line with the pulley 29, whereby a belt 32 may be placed over said pulleys instead of over the pulley of the engine. The

shaft 58 at the opposite end is provided with the balance wheel 62. Mounted upon the

bars

56 and 57 in rear of the shaft 58 is a shaft 63' which has a large gear 64 which meshes with the ear 59, whereby the shaft:

is a crank 65 to which is attached a ink 66, which extends upwardly; Carried by the rear end of theframe 1 is a standard 67, and pivoted to the up r end thereof is an o crating lever 68, t e inner end of which is pivotally connected to the link 66. The outer end of the lever 68 is provided with a handle 69, and b operating the handle up and down it will be reciprocated the same as when the engine is running.

My improved device is adapted to be used for sawing logs in the woods, and is adapted to be transported from place to place by hand through woods and cut the logs as they have fallen, and thus saving time in moving the logs to the mill.

The lower end of the frame is with feet 7 0 which may be adjuste toward the rear or forward end of the frame, and whereby the machine is tilted upon the legs, and may be rocked for allowing the saw to pass over the log, and by a slight lifting of ro'vided seen that the saw will be moved, whereby the hand-operating meanscan be readily removed when the saw is run by the engine.

The saw 4.9 when it is in its extreme inward movementextends considerably beyond the outer end of the saw-guide, in order that the saw will at all times rests upon the log. By this construction it will be seen that the machine is brought'in position so that the saw will rest upon the log and the engine is then started and the saw feet 40 to allowthe proper feed of the saw.
