SAWING-MACHINE.

Specification of Letters Patent.

Patented J une 10, 1913.

Application tiled April 21, 1911. Serial No. 622,614.

T0 all who/m, 'it may concern Be it known that we, THOMAS Lowe and THOMAS L. KING, citizens of the United States, residing at Garfield, in the county of lhitman and State of Washington, have invented certain new and useful Improvements in Sawing-Mnchines, of which the following is a specification.

It is the object of the present invention to provide an improved 4sawinfT machine for use in cross-sawing logs which have been felled, the machine being transportable and being motor-operated.

It is one aimof the invention to so construct the machine that it will be so balanced as to permit. of its being readily adjusted angularly for the purpose ot' causing' the saw to enter the log at the proper angle. 1n this connection the invention also aims to provide a machine of this type which will not be liable to overturn while in use, and

' will not be subject to any considerable vibration.

novel meansforladjusting and holding at adjustment the bpdy of the machine 'so that .embodying the present invention.

Figure 1 is a side elevation of the machine Fig. 2 is a top plan view thereof. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1. -F ig. 4 is a rear end view, the parts being shown at ne adjustment in full lines and at another a( justment in dotted lines. Fig. 5 is a detail sectional View on the line 5 5 of Fig.' 4.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the accompanying drawings, the nu meral 1 indicates a beam which constitutes the body of the machine and which is de,- signed tobe disposed at one end upon the log, or the like, being cut, and to be supported at its op osite end for angular adjustment. A sh e2 is fixed upon the beam, and mounted lfor reciprocation thereon is a cross-head The saw ofthe machine is indicatedby the numeral 4 and has rigidly connected to it an arm 5 which is pivoted to the cross-head at one side thereof, pref- The invention aims further to provide erably the righbhand side, so that the sawblade will lie wholly to this side of the beam. Reciprocatory motion is imparted `to the cross-head 3 through the medium of a pitman 6 which is connected to the cross-head and to a crank 7 upon the shaft 8 of an eX- plosive engine 9, this machine being of any ordina-ry and suitable type. A hand-crank 10 also connected with the shaft of the engine and may be manipulated to start the engine. .It will be readily understood at this point that upon operation of the engine, the cross-head 3 will be reciprocated and similar movement will be imparted t0 the saw-blade 4t which, at the beginning of the sawing operation is disposed with its toothed edge resting upon the log to be cut. As the saw-blade 4 reciprocates, it feeds, by gravity, through the log.

As before stated, the beam is arranged at one end for disposal upon the log to be cut, and at its said end is provided with a gripping means embodying two gripping arms,

one indicated by the Vnumeral 11 and the other by the numeral 12. These arms are formed with heads which are pivoted to vthe beam 1 and the heads are formed' with teeth Y 13 which mesh, thereby causing simultaneous swinging n'iovemcnt of the arms to grip or release the. log. The arms are swung into gripping engagement with the log and out of such engagement by means of a handlever 14 which is secured to or integral with the arm 122 and cooperates with a rack 15 upon the side of the beam, this rack serving to hold the lever with the pointed ends of the arms biting into thelog. As a means for supporting the other end of the beam 1, there is provided a beam 16 which is disposed upon the ground aud has, at euch end, an anchor' 17 designed to enter the ground to hold the beam against slipping. A yoke 18 is mounted to rock laterally upon the beam 1G and is formed with :1n upstanding pin 19 which passes through a slot in the Said end of the beam 1, the beam 1 being in this manner supported for vertical swing ing adjustment as well as for angular adjustment to cause the saw-blade to enter the log at the desired angle. As a means for holding thc beam 1 at different positions in the latter adjustment, there is provided a standard 2O which is secured upon the beam 1 and projects above the same, and an arm 22 which is pivoted at its lower end to the beam 1G at one cud thereof and is formed readilyl p ace to place and set with a slot 23"* through which projects a threaded stem 24 having an eye 23 slidably fitted upon the standard 20. A hand-nut 22 is threaded upon the stem 25S and may be tightened for the purpose vof holding the parts 2O and 22 lat adjustment.

Itis obvious that as the engine t) and its related parts is positioned at one side of thc beam 1 and the log-gripping' means and saw-blade 4 are positioned at the other Side of the beam, tl i .Y v erenly distributed upon the is no tendency for the latter to overturn while the machine/is in operation. Furthermore, being properly balanced, the machine may be readily adjusted angularly for the purpose of causing the saw-blade to enter the log at the desired angle. Y,

The arrangement of the .parts of the machine is such that the machine as a whole readily carried from up for use without 1s compactand may be any great exertion.

i It will be noted that the end of the distant from the worli, is lower work and so supported as to rock both longitndinally and transversely, so that it will follow the progress of tle work and be adjusted to any desired position as 'may be demanded by the location or shape of the arm 1, than l the log. It will also be noted that the. higher end of the arm rests upon the work'and that the engine and the saw are disposed at o site sides of the arm adjacent to the higher end thereof so that the weight of the arm and of the engine supported thereby will hold it to the work, and consequently buckling o f the saw during its operation will not be apt to occur.

-I-l'aving thus described the. invention what is claimed as new is:`

A sawing machine comprising an inclined Aarm adapted at its higher end to rest upon the work and provided at its lower end with a longitudinal slot, a cross beam beneath the lower end of the arm. a extending over said cross beam, a pin rising from the yoke and extendingz,r through the longitudinal slot in the lower end of the inclined arm, a standard secured to and rising from said arm, and a brace pivoted to the cross beam and adjustably connected to said standard.

n testimony whereof, we affix our signatures in presence df two witnesses.'A
