SAWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 284,038, dated August 28, 1883. application mea May is, ss. (No mofle.)

To all whom it may concern Be it known that I, GEORGE MOCOY, a citizen of the United States, residing at New Dungeness, in the county of Clallam, Territory of Vashington, have invented anew and use ful Sawing-Machine, of which the following is a specification. A

My invention relates to improvements in the manner of using drag-saws,in which the operator stands upon a treadle connected to an upright carrying a horizontal bar attached to the saw, being connected to the saw by neans of a bolt to the saw-handle. The operator having hold of the saw-handle above the horizontal bar unconsciously gains great power loy the action of the treadle in his effort to perform the work. i

The object of my invention is to increase the manual power that can be utilized to drive the drag-saw. I attain this object by the mechanism illustrated in the accompanying drawing, in which the figure is a perspective View of the entire machine.

B is the frame. Cis the treadle. D shows mechanism connecting the treadle with pivoted upright E. Upright E carries horizontal bar f, horizontal bar f being attached to the saw at g. The mechanism at D constitutes a novable joint. It consists of a block, D, pivoted between lugs on the end of the treadle, which block is perforated transversely in a line at right angles to its axis. Through the perforation slides the end of an arm, F, which is rigidly attached to the .rock-shaft G, to which upright E is secured, the arm F taking a direction at right angles to that of upright E, and being suitably braced from said uprght. 'The object of the mechanism at D is to increase the power of stroke from center to limit, thus aiding the operator in the most dif- 40 ficult position while performing the work. Upright E stands at one side of the longitudinal central line of the machine, giving the horizontal bar space to work freely by the side of the operator. g treadle C is occupied by the left foot of the 'operator. The position of the right foot is midway between the treadle-bearings and the connecting-joint with upright E7 thus giving equal power to the horizontal bar f during both the forward and backward movements. The positions of the operator7s feet should or- Adinarly be at points equidistant from the pivot or axis of the treadle. The position of the operator on the treadle, however, may be varied to give the required power while in The elevation on the end of motion,as when the saw is working at an angle. i

What I claim as my invention is- The combination, with the base lB, of treadle Cand lever E, pivoted thereto, the lever having a saw attached, as shown, said lever and treadle being connected by an arm eX- i tending from the lever and sliding through a pivoted piece on the treadle, substantially as described. t

GEORGE MOCOY.
