Description

UNITED sTATEs PATENT oEEToE.
T. GOPELAND, OF PITTSBURG',
PENNSYLVANIA.
MECHANISM FOR OPERATING SAWMILL-CARRIAGES.
Speccaton of Letters Patent No. 11,210, dated July 4, 1854:.
To all 'whomt may concern: y l
Beit known that I, A. S. T. COPELAND, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful` Improvement in Sawmills, called f A. S. T. Copelands Stationary and Portable Sawmillf7 of which the following is a specification.
The rack and gig-wheels and all` the gear- A.
ing connected therewith, of `the old sawmill are dispensed with in the improved mill, 'in the manner following, to wit, on
the one `end of `centripetal spindle I stands cam M; to cam M is connected an upright handle X which is furnished with two pins (l) on its reverse sides; said handle works through catch (2) up and down as occasion may require; on the other end of centripetal spindle I stands spring cam H and cam K; a pin in cam K works in slide of cam G; to cam G is connected a triangular shaft J which is furnished with a pinion 5; immediately under said pinion are two right and left rdouble threaded endless screws E, andthe right or left of said screws said `-pinibn works according as it is sought to move log carriage L forward or backward; thus by settingtheupper pin l of upright` poses set forth.
handle X below catch 2 triangular shaft pinion 5 is thrown into left screw 3 and three distinct reverse mot-ions are made; a pin on log'carriage L coming in Contact with latch Y sets upright handle X off catch 2, whereupon spring cam H reverses cams M, K, and Gr, and triangular shaft J to their rectilinear position, making siX reverse motions; by raising upright handle X until the lower .pin l is above catch 2 the triangular shaft pinion 5 is thrown into right screw; then second pin on log carriage 40 L coming in contact with latch Y spring cam II sets triangular shaft J in its rectilinear position, makingtwelve reverse motions.`
I claiml as my invention- The combination of the triangularly working shaft, J; the mechanism for shift'- ing it into and out of gear; with the right and left handed endless screws 3 and 4, in any manner, substantially the same as hereinbefore shown and described for the purh A. S. T. COPELAND.
