F. R. WEATHERSBY.
DRILL,
APPLICATION FILED MAY22,1919.
Patented Apr. 6, 1920.
WITNESSES A TTORNE Y8 UNITED STATES PATENT oEErcE.
FIRED RICHARD WEATHERSIBY, 0F HOUSTON, TEXAS.
DRILL.
Application filed May 22, 1919.
To all whom, it may concern Be it known that I, FRED RICHARD \VEATHERsBY, a citizen of the United States, and a resident of Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Drills, of which the following is a specification.
My invention is an improvement in drills, and has for its object to provide a simple, inexpensive, firm and rigid method of connecting drill bits to the shank, in such manner that they will not become detached, and the securing means will not be in a position to be injured or broken in operation of the drill.
In the drawings:
Figure 1 is a front view of the improved drill,
Fig. 2 is a view at right angles to Fig. 1,
Fig. 3 is a bottom plan View,
Fig. 4 is a side view of the bit detached.
In the present embodiment of the invention the drill bit 1 is a plate having upstanding threaded stems 2, the said stems being spaced apart longitudinally of the plate- The shank of the drill comprises a body which has at its upper end a threaded stem 4: for engagement by the drilling tool or support, and the body has at opposite sides radially extending ears or enlargements 5, which are vertically perforated.
The body has in its lower end a diametrical slot 6 which also cuts the lower ends of the ears 5, and within this slot the upper edge of the bit is received, as clearly shown Specification of Letters Patent.
Patented Apr. 6, 1920.
Serial No. 298,892.
in Figs. 1 and 2. The stems pass upward through the perforations of the ears or lugs, and they are engaged by nuts 7 and 8 above the ears, the nut 7 locking the nut 8. He
ferring to Fig. 1 it will be seen that the bit extends beyond the ears, and in the use of the tool, the securing means for the bit, namely the stems 2 are not in a position such that they are liable to be engaged by the wall of the hole being drilled, to injure said stems. The bit may be easily changed when dulled, merely by loosening the nuts 7 and 8. The cutting edge of the bit has its two ends beveled in opposite directions r as shown at 9, and at each end of the cutting edge there is a depending lug 10 which is beveled-on its inner face to cut. The body of the shank has vertical openings 11 on opposite sides of the slot 6 for the passage of water during the drilling.
I claim:
In combination, a shank having ears formed on the opposite sides thereof, the ears being provided with smooth openings extending entirely therethrough with their axes parallel with. the axis of the shank, said shank having its outer face provided with a transverse slot extending through the cars, a bit seated within said slot and having spaced parallel. threaded stems formed integrally thereon, the stems pass ing through and beyond the openings in the ears, and nuts threaded onto said stems and engaging the ears whereby to secure the bit within the slot.
FRED RICHARD WEATHERSBY.
