DRILL BIT.
Application 1`ed June 19, 1924. Serial No. 720,976.
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
body 3 is cylindrical, and has at Opposite lower widened part 4 oi the drill, to supply Y .10 cut and reain the wall of the drill-hole cylindrically, the interspaces at 10 being too narrow to make fiat places in the wall or on the other hand to allow thc drill to be influenced in its movements by any suchflat .spots as might occur' due to hard places in the rock. The coned hollow and crushing face 9 of the bit centers the bit, vand the dome` of ook is disintegrated atthe top by the ridge 'Having described my invention,what I claim-as new, and desire to secure by Letters Patent, is:
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.
