DRILL BIT.
To all lwhom t may concern:
Be it known that I, GEORGE R. WATSON, a citizen of the United States of America, and a resident of Waterloo, Blackhawk County,
5 Iowa, have invented certain new and useful Improvements in Drill Bits, of which the following is a specification.
My invention relates to improvements in drill-bits, and the Object of my improvement for use in efficienti drilling holes in roc formations a drill w ose bit is so shaped as to Operate as a reaming cutter and crushing means.
This object I have accomplished b th an claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is-a side elevation of my improved drill and bit,l
with a part broken away, and Fig. 2 is an elevation thereof taken at an angle of ninety degrees from the elevation shown in said Fig. 1. Fig. 3 is a plan of the bit end or face, and Fig. 4 is a cross-section of the drill body taken on the broken line 4-4 of said Fi 1. l 'he drill shankl or to 1 has an upwardl projecting coned threa ed boss 2 to :be removably received in a threaded counterpart socket in the lower end of a drill-stem. The
1.- A drill-bit -liaving a longitudinally grooved body andv afcrushing reaming head of 4larger diametcnthe crushing face of said i lWardly conically hollowcd crushing face. `and having opposite hollows` which cross'tlic Acrushing face to provide between the separatedparts of `the crushing face a medial ridge, positioned at the apex of the conical hollow.
