SAWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 246,448, dated August 30, 1881.

Application filed May 20, 1881.

To all whom it may concern.-

Be it known that I, JOHN AUGSPURGER, a citizen of the United States, residing at Trenton,'Butler county, Ohio, have invented new and useful Improvements in Sawin g-Machin es, of which the following is a specification.

My invention relates to improvements in sawing-machines for cutting standing timber, its object being to provide a practicable, efficient, and economical machine for the purpose, to be operated by manual power and be easily transported from place to place.

My invention is embodied in mechanism illustrated in the accompanying drawings, in which- Figure l is a plan view of my apparatus complete; Fig. 2, a longitudinal sectional elevation of the same; Fig. 3, a cross-sectional elevation of the same, and Fig. 4 a detail crosssection through the cross-head and saw-clamp.

Similar letters of reference indicate similar parts in both specification and drawings.

Referring to the drawings to illustrate the following description, A A designate the longitudinal bars, and B B the cross-bars, of a rectangular frame, which is supported adjustably upon four posts, 10, by suitable clamps and set-screws in any convenient manner. Upon the supporting -frame a guideway, (J, is arranged to rest and be adjustable horizontally in the following manner: It is held by a pivotbolt, w,passing verticallythrough near its rear end, and through a slot, 8, extending longitudinally through the cross-bar B, from end to end, between the bars A. By this construction the guidewayis adjustable from side to'side and held pivotally bya thumb-nut, it, upon its pivot-bolt in any desired position. The forward end of the guideway is free to move laterally on rollers r,journaled in cleats or brackets attached to the guideway O, the cross-bar B being sufficiently wide to form a support and roadwayfor the rollers. Atongue, t, projects forward beneath the crossbar B, to hold the guideway to the crossbar in its lateral movements.

The guideway consists of two parallel guiderails, c, mounted upon a supporting-piece, between and uponwhich guide=rails movesa cross head, D, constructed in the ordinary manner with side cleats projecting over above and be (No model.)

low the guide-rails, to hold and guide the crosshead. A handle, H, is attached by ahook-an (1- eye connection to the cross-head forits manip-' ulation, and to the forward end of the crosshead the saw E is secured in any convenient manner, riding upon a supporting-block, e, or roller secured upon the guidewayO atits front end. To the guideway O is also attached a rope or chain, F, which is carried under a sheave, f, and thence over a sheave,f journaled in a double-armed bracket, G, secured upon oneof the side bars,A. The bracket Gis secured in position removably upon either of the bars A, as may be required,and by means of a weight, to, at the outer end of the rope or chain the saw-guidewayand the saw are drawn to that side, the fall of the weight being pro vided for by the upwardly-extended arm of the bracket G.

The operationof my invention is as follows: The frame being placed on the ground in proper relation to the tree to be cut down and adjusted to the requiredheight, the guideway is adjusted by means of the pivot-bolt ac to the position required, the bracket G attached to the proper side bar, A, and the rope and weight adjusted in position to hold the saw toits work. Then by means of the handle H the operator reciprocates the saw, which, by adding more or less weight, is caused to cut as may be de sired.

The saw-guideway may be adjusted at will during the progress of the work,to suit the cut desired.

Having described myinvention, I claim and desire to secure by Letters Patent- 1. In a drag-sawing machine, the combination, with a supporting framework, of a laterally-swinging saw-guideway, sustained by the frame-work, and carrying a sliding crosshead to which the saw is connected, the rear pivoted end of said guideway being adjustable transversely across the supporting framework, substantially as and for the purposes described. I

2. In a drag-sawing machine, the combi* nation of a supporting frame-work having a transversely-slotted portion, 8, with a laterallyswinging saw-guideway, sustained by the frame-work, and carrying a sliding cross-head to which the saw is connected, the rear end of said guideway being pivoted on a bolt or pin, In testimony whereof I have hereunto set my which is transverselyadjustable in the slotted hand in the presence of two subscribing witportion of the frame-work, snbstan ti ally as and nesses.

for the purpose described. JOHN AUGS PURGER. 5 3. In combination with the guideway O,the Witnesses:

rollers 1', cross-bar B, pivot-bolt w, and slotted L. M. HOSEA,

cross-bar B, substantially as specified. C. P. DOOLITTLE.
