IMPROVEMENT IN LATHE-GEAR.
Specification forming part of Letters Patent No. 188,033, dated March 6, 1877; application filed February 14, 1876.
disk anda pawl on the lathe'spindle, circularsaw arbor, or a shaft for working a jig-saw, all brin g contrived so that either device may be readily connected to .or disconnected from r the driving-power, thereby enabling the power to be used for a greater variety of purposes than ordinary lathe-powers can be.
Figure 1 is partly a side elevation and partly a sectional elevation of my invention. Fig. 2 is an end elevation.
Similar letters of reference indicate corresponding parts.
A is the foot-treadle, from which a cord, B, passes up around the shaft 0, and then down to the spring D for turning the shaft forward and backward. E is aratchet-wheel on the shaft, which imparts continuous rotary motion to the balance-wheel disk F, and spindle or arbor G, by the pawl H on the disk, which catches the ratchet as it is turned forward, but lets it go back freely when the spring pulls the ratchet back, the balance-wheel continuing its motion meantime by its inertia.
The lathe-spindle, saw-arbor, or other shaft to be worked by the driving-shaft C will have a socket, l, for a bearing for one end of said shaft, and be mounted in movable bearing-blocks J, to be readily put in position and taken away as wanted. By thus dividing the shaft into two parts, and providing the part Gwith its own journals, the shaft 0 has nothing to do but speed the shaft G around, which it will do infinitely faster than can be done to a continuous shaft, by means of an encircling collar, because of the collars greater diameter. Said shafts may be made to turn a circular saw, K, ajig-saw, L, or other tool. The
jig-saw will be attached to a sliding headblock, M, working in a guide-post, N, or other approved contrivance.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the shaft G, provided with its own journals, wheel F attached thereto, shaft 0, ratchet-wheel E, dog H, cord or strap B, treadle A, and spring D, substantially as set forth.
JOHN N. TANNAHILL.
