UNITED STATES PATENT OFFICE. 1
oHRisTIAN Monson, OF Moscow, WISCONSIN.
IMPROVEMENT IN AueERs.
Specification forming .part of LettersPatent No. 104,335. dated June 14, 1870.
.To all whom it may concern:
Be it known that I, CHRISTIAN MONsoN, of
" Moscow, in the county of Iowa and State of Wisconsin, have invented a new'and useful Improvement in Angers, and I do hereby de` clare that the following 1s a full and exact description of the same, reference being had tothe accompanying drawing and to the letters of reference marked thereon.
This invention has for'its object the production of a tool which shall not only be capable of boring different sizes of holes, but shall also be especially adapted for making holes for screws, and consists in constructing Ithe tool, at certain intervals, of diiierent sizes, andl tapering in form, and the larger of the three is also provided Awith a projection, a3, by means of which it is especially adapted for countersnking. B represents a modification of the above, which is provided with two sizes of screws, and has a double thread. The point,
also, is somewhat diii'erently constructed, being provided with slight projections, which are not easily worn or broken; C also represents a modification of the first form, which is provided with two sets of screws, and has a trianguiar-shaped point. This latter form is well adapted for easily penetrating the wood, and it cannot well be broken or made dull.
The tool herein described may be used for boring different sizes of holes, and is also especially adapted for making holesfor screws, inasmuch as the vboring and countersinking may be accomplished at a single operation. The tapering form also provides for the blank part. of the screw, which is" larger than the threaded part.
Having thus. fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
A boring-tool having the parts a; .x1 a2, constructed of different sizes, and having a tapering form, as shown and described.
This specification signed and witnessed this 3d day of January 1870.
