SPECIFICATION formingpart of Letters Patent 110,463,097, dated November 10, 1891.

Application filed April 27, 1891. Serial No. 390,525. (No model.)

To all whom it may concern.-

Be it known that we, JOHN BADOLETT COAN and JAMES PAUL COAN, of Vin'cennes, in the county of Knox and State of Indiana, have in vented a new and Improved Sawing-Machine, of which the following is a full, clear, and we act description.

The object of our invention is to provide a new and improved sawing-machine which is simple and durable in construction and very eifective in operation.

The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement, with parts in section. Fig. 2 is a front end view of the same, with parts in section and the saw in a raised position; and Fig. 3 is a transverse section of the improvement on the line a; m of Fig. 1.

The improved sawing-machine is provided with a frame A, having a longitudinally-extending base-board A supporting on the u11- der side near one end a rocker A extending transversely, and on which are erected the standards A connected by curved braces A with the baseboard A and with standards A, erected on a cross-bar A, secured to the under side of the base-board A at its front end. The cross-bar A is connected at its ends by inclined arms A with the upper ends of the standards A On these arms A are held adjustable legs B, serving to raise and lower the front end of the frame according to the log to be cut.

Each of the legs B is provided on its upper end with a keeper B, fitted to slide on the respective arm A", while the lower end of the leg is engaged by a keeper B secured to the cross-bar A. On each of the legs 13 is secured a spring 0, extending with its free end above the respective leg to engage one of a series of notches A formed in the respective arm A". Each of the springs O is formed at its free end with a handle 0, serving to pull the free end of the spring out of one of the notches A in raising or lowering the legs B on the arms A. From the sides of the baseboardA extend forwardlyhandles A, adapted to be taken hold of by the operator when transporting the sawing-machine from place to place. On the opposite or rear end of the baseboard A is journaled a wheel D, adapted to travel on the ground when the operator takes hold of the handles A and raises the same so as to lift the frame A off of the ground. The machine can then be pushed forward over the ground. similarly to a Wheelbarrow. In the upper ends of the standards A is pivoted a link E, pivotally connected at their lower ends with a platform F, extending horizontally in line with and above the base-board A. The front end of the platform F is pivotally connected with a lever G, arranged parallel to the link E and pivoted in the upper end of the standard A. ward above the standards, andthis extension G is formed with one or more sets of handles G adapted to be taken hold of by the operator supported on the platform F. The front end of the platform F is also provided with a head F, pivotally connected with the handle H of the saw H of any approved construction. On the handle II is arranged a ring I, adapted to be engaged by a hook J, pivoted on the lever G and serving to hold the saw H in an uppermost position when-the sawing-machine is to be transported from place to place, as previously described. When the saw is in this uppermost position, (illustrated in Fig. 2,) the handles A are unobstructed, so as to be taken hold of by the operator.

At or near the middle of the platform F are held one or more links K, extending upwardly and pivotally connected with an arm L, pivoted to the link E. On this arm L is supported a seat N, in which the operator Working the sawing-machine is seated, resting his feet 011 the platform F and taking hold by his hands on the handles G The seat N and connecting-supports may be omitted. The operator then stands on the ground to work the machine.

The machine is used as follows: The frame A rests on its rear end 011 the rocker A the front end of the said frame being adjust-ed according to the size of the log to be sawed The lever G extends up and according to the unevenness of the ground. When the several parts arein the position shown in Fig. 1, the saw H is passed trans- Versely across the log, and then the operator seats himself in the seat N and takes hold of the handles G and pulls on the said handles, so as to impart a swinging motion to the lever G, whereby the platform is caused to rock forward and backward, assisted by the operator, who follows with his body the motion imparted to the lever G, thus giving momentum to the said platform F. The saw H is thus readily dragged across the" log and thereby cuts the same. The links K are made adjustable on the platform Gr, so as to raise and lower the seat N to conveniently seat the operator.

It will be seen that the machine is very simple and durable in construction and can be readily moved about from place to place.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. In a sawing-machine, the combination, with a supporting-frame, of a link pivoted at one end in the upper part of the frame, a lever pivoted between its ends to the upper part of the frame and provided with handles at its upper end, a platform pivoted to the lower ends of the link and lever and adapted to be pivotally connected to a saw, and a seat carried by the platform, substantially as described.

2. In a sawing-machine, the combination,

,with a supporting-frame, of a link pivoted at its upper end to the frame,alever pivoted between its ends at the opposite end of the frame and provided with handles at the upper end, a platform pivoted to the lower ends of the link and lever, upwardly-projecting links secured to the platform, an arm pivotally connected to the link pivoted to the frame and to the links secured to the platform, and a seat on the said arm, substantially as herein shown and described.

3. In a sawing-machine, the combination, with a frame provided with sets of standards and legs for adjusting the front end of the said frame, of a link pivoted on one set of standards, a hand-lever pivoted on the other setof standards, arranged parallel with the said link, a platform pivotally connecting the said link with the said lever, and a head formed on the said platform and pivotally connected with the handle of the saw, substantially as shown and described.

4. A sawing-machine comprising a frame having a wheel mounted on one end and provided with handles projecting from the opposite end, a linkhavingits upper end pivoted to one end of the frame, a leverpivotedto the other end of the frame at about its middle, a platform pivoted to the lower ends of the link and lever, and a seat carried by the platform, substantially as herein shown and described.

5. In a sawing-machine, the combination, with a frame provided at its rear end with a rocker and at its front end with independentlyadjustable legs, of alink pivotally connected with the rear end of the said frame, a handlever pivotally connected with the front end of the said frame, a platform provided with a head and pivotally connecting the saidlink with the said lever. a saw pivotally connected with the said head, arms connected with the said link, rods connected with the said arms and supported from the said platform, and a seat supported on the said arms, substantially as shown and described.
