WM. A. L. KIRK, on HAMILTON, oHIo.
IMPROVEMENT IN SAWING-MACHINES.
Specification forming part of LettershPatent hlm/19,279, dated August 8, 1865.
To all whom it may concern:
Be it known that I, WILLIAM A. L. KIRK, of Hamilton, Butler county, Ohio, have in vented anew and useful Improvement in Machines for Crosscutting Logs; and I do hereby declare the following to be afull, clear, and eXactdescription thereof', reference being had to the accompanying drawings, making part of this specification.
My invention relates to a mechanical arrangement whereby the saw receives a combined reciprocating and rocking motion similar to that imparted Vby'hand, so as to cut whollyfrom the center ot' the log outward and to clear the kerf of sawdust at every stroke, the same resulting in a smooth, rapid, and effective cut.
Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 represents, by perspective view, a somewhat more complex machine embodying the same principle.
A is a shaft, rotated in direction of arrow by steam, or horse, or other power, and having a crank, B, for the attachment of a pitman, C, whose other extremity is pivoled to a crosshead, D, which is coniined to a rectilinear lpath, at right angles to the shalt A by means of customary ways E.
The com bined reciprocating and rocking motion of the saw F is obtained by pivoting it to the pitman G at some point intermediate between the extremities of the latter, the said point of attachment being selected at a greater or less distance from thecross-head D, according to the amount of rocking motion desired.' This distance,when about one-fifth ofthelength ot' the piston, I Vhave found to be effective. The shaft A may carry a `iiy-wheel, G, and
the wrist of the crank may project therefrom, as in the illustration.
A yoke, H, may be employed for restraining the lsaw to its proper vertical plane.
` I represents a log-truck provided withwheels t', which occupy a railway, J.
K is a roller, on which the front end of the. y
log is supported and by which it is set forward. L is a clamp for securing the login place. While disclaiming novelty in the general Vprinciple ot' imparting a rocking motion to a
