UNITED STATES PATENT OFFICE.
THOMAS D. PARSONS, OF BRISTOL, CONNECTICUT, ASSIGNOR TO HIMSELF AND GEORGE T. STEELE, OF SAME PLACE.
IMPROVEMENT IN AUGERS.
Specification forming part of Letters Patent N 166,221, dated August 3, 1875 application filed July 12, 1875.

Be it known that I, THOMAS D. PARSONS, of Bristol, county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Angers and to enable others skilled in the art to make the same I will proceed to describe, referring to the drawing, in which the same letters indicate like parts in each of the figures. V
The nature of this invention consists in the peculiar construction or formation of the cutting-lips, and the arrangement of the cuttingspurs. I
In the accompanying drawing, Figure l is a front elevation. Fig. 2 is a side elevation. Fig. 3 is an end view.
a is the body of a bit or anger. ter point or screw. cutting-spurs.
These cutting-spurs cl are arranged on the outer edge of the body of the bit or anger, and at a distance of one-fourth of an inch (more or less) back from the edge of the cut- I) is a cenc are cutter-lips. d are ting-lips to allow them (the cutting-lips) to be more convenient to sharpen. The front or cutting edge of said lips recedes or is partially V-shape, and the surface or face portion of the cutter-lips are a A or convex shape, which produces a free and easy out. Thus it will be seen that this bit or anger can be easily and perfectly sharpened when required, and will
