To all 'whom it may concern:

Be it known that I, lVILLIAM WVETHERBEE, a citizen of the United Statesrresiding at Cokedal'e, in the county of Las Animas and State of Colorado, have invented certain.

new and useful Improvements in Drilling,

Machines; and I doideclare the following to be a full, clear, and exact description of the invention, such as wllenable othersf-' skilled in the art to which it appertains to features of construction,combination and arra-ngemmit of parts, as will belinore fully the appended claims. i

In the accon'ipanylng draw1ngs,'Figure 1 described and ,particularly 'pointed out in is a sideview of the inachine, showing the saine in operative position; Fig. 2 is a vertical section through the drill operating shatton the line Q-2 of Fig. 1, sh'owlng 4an edge view ot' the machine, with certain parts removed; F i". 3 is a horizontal "sectional' view on the line f'l--i of Fig. 1'; Fig. 4 is a detail side view ot' the adjustable snp' porting block for the drill operating mechanisni'; Figi 5 a detail sectional view on the line 5-5 of 11`jg.'3; Fig. 6 is a detail side view of the ratchet wrench or handle for turning the 'drill operating shaft in close pl aces.

`Referring n iore 'particularly tothe drawings,l 1 ldenotes a tubular supporting post, in one/end of which is slidably mounted a 'pointed anchoring bar 2 which is held-in adjusted position in the'end of the post by means of a .set screw 3.y The opposite end .of the post is provided with. interior Screw" threads and'with said threaded end is en'- -gaged a jack-screw 4 having a. pointed outer .supporting block 5 whiciris adjustably secured to the post at iany desired position by a set screw (i. Af Ihe block 5 projects laterally at one side ofthe post and in said laterally projecting portion, is formed a horilvzonta-lly.disposed- 'T-shaped slot T, at 'thc passage 8. ".Adapte'd tofbe supported by theblockisa heal-infr box 9 to one side of which is passage 8 of 4the block and the bolt then moved along the horizontal portion of the tical portion o the slot, asshown. lVhr-n the bolt is thus engaged with the, slot., the 4bearing box 9 will closely engage one side of the blot-.ltdwhile the head 1 of the holtwill bind against the opposite side of the block thus vpivotallysecuringthe box t) in enfugenient with the bloek.-

`he bearing box t) has-formed therein.

with which is engaged a drill supporting and operating shaft. 12. The shaft threaded throughout its length and is. proi-ided'with ailongtudinallyalisposed groove onkey-way 13 whih extends` from one end of-the shaft to the other. )n omx end of the shaft4 12 is detachahly'monntwl an oper'- ating wheel 11 having a crank handle l5 by means of which the shaft. is revolved in drill. On the opposite rnd ofthe shaft l2 suitable drilll. y

IOn the threaded shaft. 12 is loosely inounted a bevel operating gear 18, said gear being provided with a key or feather which is engaged with the groove or key-Way 13 in the shaft 12, thereby operatively connecting the gear to the shaft. The hub of the the.a.djacent end of the hearing box 9, and

9. By thus connecting the gear 18 with the bearing box, the gear is heldin position to revolve the shaft-12 by-means of the key which engages thegroove' l'and at the inner end of -which is formed an enlargedV end of thebolt 10 is inserted through the a longitudinally'.disposed threaded passage,-

is secured a chuck 16- for the reception of a.

Specification of Letters Iatent. 'Patnted J an. 24, 1911.` applicativa med Novemberi?, 190e;l serial Nuffsaafrss.

Secured a4 astning stud or bolt 10 haring slotr'v and enga 'ed-with one end of the ver- .fio

the bearing box t) to feed and operate the .gear 1S is extended inwardly and engages 'this extended portion is provided with ,an

annular groove 19 in which is engaged a.' gearfholding stud 20, arranged upon an ex-v l tension upon either end of the bearing box j same timepermits the 4shaft to be fed forwardly by reason of its threaded engagement with the 1passage in the bearing box 9.

Secured tot e upper side of the bearing l'box 49 is a bearing bracket or hanger 21 in lwhich is mounted a driyeshaft 22, the in. ner end of which is revolublyvengaged with a bearing'socket 23 formed in one side of I j the box 9, as shown.y The 'outer end of the 10.

tive engagement with the-gear 1S and is adapted to drive said gear when the shaft- .22 is turned. The bearing bracket or hanger 21 is preferably detachably secured to the box 9 by means of stl'ids25 which engage sockets formed in the side of the box and by -mea-ns of a 4thumb screw 2G which is adapted to be' screwed into 'engagement with-a bracket to the box, the-latten'the gear 24 and the shaftl 22 maybe readily removedwhen desired. By providing the operatingV gears 1S and 24E, the shaft 12 may be" o pf eratedv thereby or'by means ofthe hand Wheel 14: secured to the outer end thereof.-

In the use of the machine, it is frequently necessary to bore holes so'close to the floor,

l ceiling or side Walls of a passage, that the operating whe-el 14 or the crank handle of the shaft 22 cannot be employed for revolving the drill" operating shaft 12, and in'such a contingency, I employ a suitable. ratchetivrench '28, preferably as is shown in Fig. G of the drawings, Ai'or turning' the operating shaft 12 of the drill, said wrench being engaged wyith the'shaft after the hand-Wheel 14 has been removed therefrom. The shaft engaging portion 29 of the Wrench is provided with a key 30 which is adapted to slidably engage the key-Way in the shaft, whereby the latter is trned when the Wrench is'pperated.

Fromthe foregoing description, taken in connection .with the 4accompanying ings, the constriiction and operation of the drawinvention will be readily understood without requiring a more extended explanation.

Various-changes in the form, proportion and the minor be resorted to Without departing from the principle or sacrificing any 'of the advantages of the invention, as defined in the appended claims.

Having thus I claim is:

l. .The cornbination of a supporting blocln a bearing box secured against one side of the supporting block, a drill shaft mounted in said bearing box, a gear Wheel slidably engaging said'shaft adjacent the 4end of the bearing box and having a grooved hub, a stop on` the end of the bearing box engaging said grooved hub, a bracket secured on the upper side of the bearingbox andv projectingV laterally therefrom, a vshaft inserted through the'end of said bracket and having one end jonrnaled in the side ofthe bearing box, and a gear Wheel on said shaft between the end ofthe .bracket and the side ofl the .bearing box. and' meshing with the' gear wheel on the drill shaft.. 2. The combination ofa. supporting block,

same and having sockets in its top, a bracket -tted in the top of the bearing box and having a depending arm spaced laterally from ldetails of construction may a bearing box secured against one side of the saidbox, a .stud in the under side of. the

bracketl engaging -'the socket i'n the bearing box, a thumb screw mounted in the bracket and engaging another socket in the bearing dbox,` a. drill shaft extending through the bearing box, a gear Wheel slidably fitted .on

the drill shaft, a stop on the en'd of the lbearing box engaging said gear wheel,. a

shaft supported by the bracket and' having one end journaled inthe side of the bearing box, and a genwheel on said shaft between the bracket and :the side of the bearing box.
