Description

to which my invention appertains to make and Unire Srarns ATENT OFFICE.,

JOHN C. MILLS, OE ROCHESTER, NEW YORK, ASSIGNOR TO HIMSELE AND RICHARD LEAKE,

IMPROVEMENT IN AUSER-BITS.

Specificationforming part of Letters Patent No. H l "2,063, dated February Ll, 1871.

To all whom t may concern:

Be it known that I, JOHN C. MILLs, of Rochester, in the county of Monroe, and in the State of New York, have invented certain new and useful Improvements in Augerits; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construct-ion and arrangement of an adjustable auger-bit, as will be hereinafter more fully set forth.

In order to enable others skilled in the art use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in whichd Figure 1 is a side view oi' my auger-bit contracted to its narrowest limit. Fig. 2 is a view of the opposite side thereof, showing the auger-bit expanded toits utmost limit, and Fig. 3 is a section of the same.

A represents the shaft, provided at its lower end with the usual screw or auger, a. For a suitable distance above this lower end the shaft A is flattened, and on each side thereof is placed aplate or bar, B, pivoted at their upper ends by means of ascrew, b. Thelower ends of the bars B B are formed, as shown, with a beveled cutter, d, having at its outer edge a downward projecting knife, e. The attened portion of the shaft A is slotted longitudinally for asnitable distance, and through the same is passed a headed screw-bolt, f, which also passes through inclined slots in the two bars B B, and upon the end of said bolt is placed a nut, h, provided with projections t on its under side. These projections are inserted in the slot on the bar B on that side, and prevent the nut from turning.

The operation of this bit is readily seen. By loosening the bolt and sliding the same up or down in the slot on the shaft A, the jaws of the bit are expanded or contracted, so that the bit may be set for any-sized hole desired to be made.

Having thus fully described my invention, I disclaim an extension-bit with the adj ust-ingscrew passing longitudinally through the eutters and the shaft; but

XVhat I claim as new, and desire to secure by Letters Patent, is-

The combination of the slotted shaft A, with its screw or auger a, the slotted plates or bars B B, with their cutters d d and e e,t11e screw b, and the bolt f, all constructed and arranged as described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 16th day of December, 1870.

JOHN C. MILLS. [L s] Vitnesses:

C. L. EvnRT, Onlus GAFFIN.
