V.Application 1e`d March 20, 1907. Serial No. 363|4=76- To all whom 'it may concern:
Be it known that we, AARON E. JENNINGS l and JAMES W. JENNINGs, citizens of the United States, residing at Central City, in the county 4of Muhlenberg and State of Kentuoky, have invented new and useful Improvements in Drills, ofwhich' the 'following is a specification.
This invention relates to drills for mining purposes; and the object thereof is to construct a drill .of such class in a manner as provision is made for the employing of drills manufacture.
. of dierent lengths for boring holes o f different depth, and. furthermore, provlsion is made whereby it is not necessary to discard the drill as an entirety if the bit should become broken, as would be the case if the shank and bit were formedof one element.
lFurther ob'ects of the invention are to' provide andri for mining purposes'which shall be simple in its construction, strong, durable, efficlent 1n its use, embodying means whereby the bit can be rigidlysecured to the shank 1n a convenient manner' and readily separated therefrom' when occasion so requires, and comparatively mexpenslve to .With the foregoing and. other objects in view, the invention consists of the novel construction, combination and arrangement of parts hereinafter more speciiically-desc'ribed and illustrated'in the accompanying drawings wherein is shown the preferred embodiment o f the invention,but it is to be understood thatI changes, variations and modifications can be resorted to which come Within the scope of the claims hereunto a pended.
' In describing 'theinvention in dtail reference 1s had to the' accompanying drawings wherein like characters denote corresponding partsthroughout the several views, and in which y "Figure 1l is a from View oft-"drin 11i aecordance with this invention; Fig. 2 isv an edgeview; Fig. 3-is a perspective view of the' bit; IF 4v is a like view of the shank,I and, 5 1s a section on line 5 5 (Fig. 1). Fig; 6 ustrates a modified form of drill showing ythe twist or spiral continued throughout.
The drill shown is ofthe screw or'serpenlwith respect to each other.
or vice versa.
tine class and embodies a shank section 1 and a bit section 2, the latter being detachably connected with the.\former so that when'the sections are secured together the bit section will not be capable of lateral or longitudinalf The'upper portion of the bit section 2, ap-` proximatelyjcentrally thereof, is shouldered as at 8, so as to form the portions 9 10, the former being offset from the latter, or in other words the portions 9 10 are not positioned in the same plane.l Each of the portions 9-10 is provided with an opening 11 and these openings 11 are adapted to register with the openings 7 The inclined portion 8 at its top is notched as at 12a. The openings 7, 11 are provided to receive hold-fast devices indicated by the reference character 12,
yfor securingthe two sections together so as to prevent any longitudinal movement of the it section with respect to the shank section, or vice versa.
When the sections are secured together the bit section is adapted to be inserted in the shank section and in such a manner that the oifset portion 6 of th shank will overlap the portion'9 of the bit an the portion 10 of the bit will overlap the odset portion 5 of the shank. By such an arrangement after the hold-fast devices 13; are secured in position the bit section is prevented from any lateral movement with respect to the shank section i The inter-engaging of the sections in a manner as stated, and the securing of the same together. bythe holde'fast devices 13 forms a rigid connection between the sections, and further, owing torthe manner in which the sections are constructed,- provision is made kfor the employing of sections ofvarying lengths and further, if one section becomes damaged it is' not necessary to throw the entire drill away as the undamaged sections canv be used.
Fig. -6 shows the drill with the twist or spiral continued throughout .so as4 to dispense with the flattened portion as shown in Figs. 1 and`2.
What I claimvis l .l 4 A drill for purposes comprising a AARON EDWIN JENNINCs AND JAMES WILLIAM JENNINCS, or CENTRAL CITY, KENTUCKY,
shank section and a bit'seotion, said shank section having its lower portion formed with a' pair of tongues offsetvwith respect to'each other, said blt section having its upger porbit section and VIneans for securing the shank section to the bit section.v Y
