' such anapparatus with improved 'means for controlling the rodline which is sure in operation and conveniently operable by an operator at hisstation near the drillingme'chay nism. i'still urther'object of my invention is to provide an improvedfeed controlling mechanism especially adapted `to use 4in conl nectionwith a griet stem whereby the rod line may be rotatedA while being lowered.

.These and other'objec'ts and advantages of -my invention will hereinafter morel fully appear.

ln the accompanyino drawings l have shownJ for purposesof illustration one. form which my invention may assume practice. ln these drawings,- i Fig. 1 is a frontelevation' partially in sec tion showing a drilling Yapparatus of the hydraulic core drill type equipped with'my improvement.

' 4Fig.2 is an' enlarged detail view .ofl the controlling mechanism,- certain partsbeing shownin section to facilitate illustration.

Fig. 3 is a detail view of part of this mecha'- nism. "1' -Y f Fig.A 1 1 is a transverse sectional view of the griefstem. y In this illustrative construction I have shown my improvement as applied to a core drilloi a well known commercial 'type com. prising a hydraulic feeding cylinderand piss `ton 1, a lioistilngdrum 2, and rod line rotatcontrolling or upper -releasable chuck mechaing mechanism 43,.both of the-latter b eing a lower chuck mechanism is .provided beneath the cylinder and avusual swivel head 6 is disposed Iabove the latter, the construction being such thatthe rod line-may be fed longitudinally relative` to the hydraulicv cylinder and rotated while it is fed, improved nism, generally dz'asign'ated 7 and hereafter more particularly described, being lherein disposed above the swivel head 6. More specifically 'it will be observed that the larger' surfaces 1 5.

Atube' 6a is secured to the feed piston and eX-` vtends upwardly within the usual swivel head 6. The collated upper end of. the tubea is journaled in -usual ball thrustbearings 7a-supported within the swivel head 6. It

the inner tubev and consequently the grief stem` 8 while'theouter'tubeiermits the feeding of the grle stem upwar ly or downward- `will thus be evident that the gear 3 drives l'y as desired, the thrust of the rod line being y absorbed by the thrust bearings 7- within the swivel lieadj 6, all as art. Referring more particularlyto thisconstruc--.

tion, it will be noted that herein a grief stem well known in, the

8 of square .cross section is extendedthrough the machine, .this stempassing 'through the 'chuck mechanism 7, the head' 6, the cylinder 1 and the lower, chuck 5, thefchuck mechanism 7 being adapted to control ythe freedom oit movement ofthe stem 8 from a point adjacent the front of the drill as through .a suit; able operating member 9. Considering the'v upper chuck mechanismv 7 vmore specincally, "it will be notedthat. it comprises a casingv vmember lothreaded as at 11 onthetubular I.

member 5b. rotated by the rotation mecha-- knismv and through which the stein'S yispassed.

Moreover, it will benotedthat this member 10 -has an enlarged generally vcup-shaped upper xportion 12 carrying a plurality vof wedge-like stem l'gripping members or slips 13 herein founadapted to grip the'four surfaces of the square stem and for this purpose provided withk gripping surfaces 14 ont-heir inner sirfaces andfop'positewedge surfacesV 15 adapted to cooperate with corresponding surfaces on the member 12. Herein, it will be noted that these members 13 are 'each provided with pins 16 adapted to move insulta-l ble guides 17 and themember 12'-, Ithe guides 17 hereinbeing disposed parallel to the wedge Attention is also directed to the fact thata cover plate 1 8 having an, axial opening therein. for the stem, is disposed over .the member 12 in such manner as secnre ly to retain the members 13 in operative relation.' Itwill also bev noted that each of one of its ends at 27 and having a longer arm yciitending outward from the latter pivot and pivoted at 2S to the upper end of the member 9.

In operation the gripping members 13 op- .erate by the wedge principle to hold the stem 8 andits connected rod line against down-l ward movement from any given position and are releasable and connectible at will in such manner as to facilitate feeding. Thus, for example, when the feeding. mechanism has been operated until the piston of the hydraulic feed 1 is at the bottom of the cylinder, the stem 8 is connected to the 'hoist 2 through a usual connection and operated in such manner that lthe weight of the stein 8 and rod line connected thereto is carried by the hoist. Then the lower chuck 5 is released and the member 9 is pulled down to throw up the short end of the lever 26 which in turn causes the members 13 to be raised and thereby release the stem 8 so that the piston of the hydraulic feeding mechanism 1 may be run up for a fresh feed. llhen the hydraulic has thus been run up, the member 9 is againpushed up in such manner as to cause the jaws 13 to grip the stein and the lower chuck 5 is 4then reset, whereupon the weight of the rod 8 and `rod line is'released from the hoist by slackening the usual connections and the feeding apparatus is prepared to feed down` a further. section of rod line. Another mode of operation is to set the clamp on the rods when the hydraulic piston is an inch'or two from its lowest position and then run the piston down to release the jawsof the top clutch, this modeof operation minimizing .clutehh-andling and the need for starting the hoist.

Further, it will be noted that I have herein shown my improvement as applied to use in v `vrconnection with a core drill, it being espe'-A i mud or sand in the bottom of the vhole and.

cially desirable to operate a grief stem with such a drill where there is a large amount of rotation of the rod line during lowering isaecordin'gly desirable, or when the drill is doing lishtailing as during drilling in soft strata of no value, my improved construction wherein the 4coaxially -disposel hydraulic mecha- -nism imposes no limitation on the length of feed while vthe stemd isV rotating, enabling a core drill to operate with the facility of a rotary in meeting either of these conditions.

More particularly it will be noted that with my improved construction when lowering the rods by the hoist and simultaneously rotating the same, the mechanism 7 may be released, the grief stem 8 then being turnedby the rotating mechanism through Ithe usual lower chuck 5 which for the purpose is preferably,u provided with smooth jaws of suitable con-r formation or-a suitable apertured pla'te as seems most desirable, although obviously if desired rotation may be effected through the top chuck mechanism in a similar manner.

ing mechanisms of well known commercial types now in general use. Attention is here also directed to the fact that when stems or rods of different section are used members 13 having different 'shaped gripping surfaces may be substituted readily.

lNhile I have in this application specifically described one form which my invention may assumein practice, it will be understood that this form of the same is shown for purposes of illust-ration and that the invention may be modified and embodied in various other forms and applied to other drills than core drills without departing from its spirit or the scope of the appended claims.
