MINERS DRILL.
SPECIFICATION forming part of Letters Patent No. 616,273, dated December 20, 1898.
Application filed May 12, 1898. serial No. 680,528. (No model.)
To all whom it may concern.-
Be it known that we, JOEL F. STRAUSER and HARRY T. KLINGER, citizens of the-United States, residing at Tower City, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Miners Drills, of which the following is a specification.
Our invention relates to miners drills; and its object is to provide an improved construction of the same which shall possess superior advantages with respect to efficiency in use.
The invention consists, essentially,in a drill formed with a down wardly-extending central portion formed with four beveled or wedgeshaped cutters at right angles to each other and a corresponding number of tapering or wedge-shaped side cutters located above the central cutters and extending outwardly at an angle to the body of the drill, as hereinafter fully described and claimed.
In the accompanying drawings, Figure 1 is a perspective View of a drill constructed in accordance with our invention. Fig. 2 is a section of the same. Fig. 3 is a bottom View.
In the said drawings the reference-numeral l designates the body of the drill, provided with a shank 2, adapted to engage with a socket in a drill-rod.- Formed integral with said body is a downwardly-extending portion 3, provided with four wedge-shaped cutters 4 at right angles to and integral with each other. These cutters, as will be seen, are
beveled on opposite sides, so as to form clearance-spaces for the material cut thereby. Located above said central cutters is acorresponding number of cutters 5, which are tacutters first cut the coal, stone, or other ma= terial and are followed by the side cutters, which enlarge the hole cut by said central cutters, being, in efiect, reamers.
By locating the side cutters in the same vertical plane I with the center cutters not only will the cutting be performed more efficiently by reason of the said cutters following the center cutters, so as to intersect the cut made by the latter, but the cut or powdered material will readily pass by the cutters, preventing clogging of the same.
Having thus fully described our invention, what we claim is- As an improved article, a miners drill consisting of the body portion, the downwardlyextending central portion formed with four vertical wedge-shaped or beveled cutters at right angles to each other, and the inner ends meeting at a common point, and the outwardly-inclined tapering or Wedge -shaped side cutters, located above and in the same vertical plane with said central cutters, but
having their cutting edges at a right anglethereto, substantially as described.
In testimony whereof we have hereunto set our hands in presence of two subscribing wit- HOSSGS.
JOEL F. STRAUSER. HARRY T. KLINGER. IVitnesses:
ROBERT S. BATHORE, DAVID M. MELLON.
