Joseph A. Miller - patent attorney
Figure I is a top view of the improved grinding-machine. (The two broken lines indicate the position of the center-line of the table to which the head and foot stocks are secured when the table is swung on either the central or the end pin.) Pig. 2 is a front elevation of the machine. Pig. 3 is an enlarged sectional view through the center of the grinding-machine, the base being shown as broken off. Fig. 4 is a plan view of the laterally-swinging base-plate, on which the wheel-arbor is supported, in different positions. The object of this invention is to so construct a grinding-machine that the same shall be adapted to do a great variety of work a machine on which straight, tapering, curved, and irregular work, either inside or outside, can be ground with great accuracy. The nature of the invention consists in the arrangement of the parts, by which the relative positions of the table, the head and foot stocks, and the wheel-arbor, can be adjusted to adapt the same to a great variety of work and under all the changes control the adjustment with the greatest nicety. |
