UNITED STATES PATENT OFFICE.
I BENJAMIN FORSTNER, OF SALEM, ASSIGNOR OF ONE-HALF HIS RIGHT TO- EDGAR 0. SMITH, OF ALBANY, OREGON.
IMPROVEMENT IN AUGERS.
Specification forming part of Letters Patent No. 155,148, dated September 22, 1874; application filed August To all whom it may concern:
Be it known that I, BENJAMIN FORSTNER, of the city of Salem, in the county of Marion, in the State of Oregon, hzwe invented a new and useful Improvement on an Auger for Boring Holes in Wood; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, which are made a part of these specifications.
This invention consists in providing the cuttin g part of an anger or bit with a circular cutting band or flange,in connection with a suitable cutting-lip, the band and lip being located nearly in the same horizontal plane, as will be fully described hereinafter.
In the drawings, Figures 1 and 4 represent views of side elevations of my invention; Figs. 2 and 6, sectional elevations, and Figs. 3 and 5 plan views.
To enable others skilled in the art to make and use my invention, I will now proceed to describe fully its construction and manner of operation.
4 represents a circular band or flange, provided with a cutting-edge, as shown; and a, a cutting-lip of any suitable construction, the
[ cutting-edges of each being located on nearly the same horizontal plane as shown. The advantages of this peculiar construction are very marked. The circular band serves to guide the bit accurately in its movement, and also give the hole that is bored a smooth and perfect finish.
By its employment the gimlet-point may be dispensed with, and as the cutting-lips do not project beyond its horizontal plane, it follows that the wood is not out beyond the line operated upon by the circular cutting-edge of the band.
By means of this peculiar construction, also, there is no tendency to split the wood or to follow the grain.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The auger having the circular cutting-band and cutting-lip located in nearly the same horizontal plane, as and. for the purpose described.
