Specification of Letters Patent.
Patented July 10, 1 906 Application flied January lfl, 1908. Serial No. 395,514.
To cl; whom it. may concern: Be it known that I, JAMES THOMAS PAR KER, a citizen of the United States, residin at Hattiesburg, in the county of Perry an have invented a new and useful Auger-Bit, of which the following is a specification.
This invention relates to adjustable augerbits, and has for an object to rovide a bit cienc r 7 A fi rrther ob'ect of the invention is to provide im roved means for attaching 9, rsdially-a' justable auxiliary cutter to an ordi new twist-bit:
ith these and other objects in view the present invention consists in the combina tion and arrangement of parts, as will he hereinafter full r described, shown in the accompanying rawings, and particularly pointed out in .the appended claims, itbeing understood that changesin the form, .proportion, size, and minor details may be made without deperting'from the spirit or sacri: ficing any of the advantages of this invention.
improved attachment in side elevation applied to an ordinary twist-bit and producing an adjustable bit. Fig. 2 is a view of the hit in reverse side elevation. Fig. 3 is a lonigitudinal sectional view of the bit, taken on me 3 3 'of Figs. 1 and 2. Fig. 4 is a plan View of the lower end of the bit as seen on arrow 4 of Fl 5. 1 and 2. Fi .5 is a tive view of t e sheath detafiied. 7 Like characters of reference indicate corresponding parts in all of the figures of the drawings. i .The attachment forming the subject-matter'bf this application isfadapted to be applied to a twist-bit 10 struction, havin the usual'worrn 11 and cutting edges 12. in
side a cavity 14, pro ortionedto conform to the spiraiity of t is it upon which it is to sheath is provided with a yoke i5, proper to form with that portion of; the. sheath a complete bit-encirclin and witha set-screw 16, inserted t .ough the g. the periphel .01 the bitcmbodying new and improve features of economy, simplicity, conven ence, and cilimunieating 'with the mortise 1?;
In the dravvings, Figure 1 is a viewcfthe) perspecof the ordinary conits preferred embodiment 'them proved attachment comprises a sheath, 7 (designated as a whole at 13,) having'in one be employed; Adjacent its lower end the member,
is provided with a transverse mortise 17 and with a groove 18, parallel therewith and at the lowest extremity. Within the mortise and cove is mounted the auxiliary cutter l9, bifurcated b the longitudinal slot 20 to form the paralle being disposed within the mortise and the latter within the groove. The arrn' 21 is provided along its up or edge with serrations or notches 23 and 7 lower side with the curved cutting edge 24,
terniinating in a cutting-point The an openingfifi,
is claimed isthe arm 22 along its aving thus described the invention, what arms 21 and 22, the former .1. auger, a bar molded to fit one side ed to em of the auger and provided with a yoke adaptable cutter sildably'mounted inths yoke and previded with a. serrated edge, a detent carried hythebar and arranged to engage the serrated edge of. the cutter. and an eccentric for operating the detent. I
2. Ina tmst augega-har mpldedito fit one race said auge'r,a radially-adjustside of the au er and provided with a yoke adapted to em race the auger, said yoke being provided with a transverse mortise and a terminal shoulder, means for detachably securing the bar to the au er, and a radiallyadjustable cutter former? with spaced arms one of which engages the mortise and the other the shoulder.
3. In an auger, a bar molded to fit one side of the auger and provided with a yoke ada ted to embrace the auger, a,cutter slida ly mounted in the yoke and having a serrated edge, a detent carried by the bar and adapted to engage the serrated edge of the cutter, and
[5 means piercing the yoke and engaging the auger for securing the bar in position on said auger.
4. In a twist-auger a bar molded to fit one side of the au er and provided with a yoke adapted to em race said auger, there being a transverse mortise formed in the yoke, an
auxiliar cutter slidably mounted in the mortise at the cutting edge of the auger and ad justable radially with respect to.said auger,
' 5. All ad ust abIe auger comprising an all er-bit having a worm and a cutting edge, a
er molded to fit one side of the au er and 0 provided with a yoke embracing sai' au er at the cutting edge thereof, a cutter slida ly mounted in the oke and provided with a serrated edge, a etent slida'bly mounted on the bar for enga ement with the serrated ,3 5 edge of cutter an provided with a terminal hook, and an eccentric engaging said hook for moving the detent to operative position.
6. An adjustable au er comprising a twistbit having a Worm an a cutting edge, a bar molded to fit one side of the bit and rovided 40 with a oke adapted to embrace t e auger, means or clampmg the bar on the au er, a radially-adjustable auxiliary cutter sli ably mounted in the oke and havin a serrated edge, a detent s idably mounte on the bar 5 and adapted to engage the serrated edge of the cutter, and an eccentric engagingithedetent and provided with an. operating-handle for moving the detent to operative and inoperative position. v
7 An adjustable auger comprising a twistbit having a worm and a cutting edge, a
sheath disposed upon the bit and molded to a conform to the spirality of the bit, means for clamping the sheath and bit together, an'auxiliary cutter slidably mounted on the sheath and having a serrated ed e,. a detentca'rried by the sheath and adapte to enga' e the.serrated edge of the cutter, a hook carried by the detent, and a lever pivoted upon the sheath 6,0 and having an eccentric flanlge engaging the hook for operating the hand e.
In testimony that I claim the foregoing as my own I have hereto a'ffixed my signature in the presence of two witnesses.
