(ol. 25e-$1) This invention pertains lbroadly :td drilling a-pparatus, but more particularly to supporting rigs for fluid actuated vdrills commonly known as wagon drills. 5A One object of this invention is to produce an improved drilling apparatus of the wagon drill type. . - Another object of this invention is to provide a wagon drill with a mechanism lwhereby the 1.o: drill maybe positioned -for drilling holes <in di-f ferent positions relative »to the framev supporting the drill, land may be >adjusted vertically 'and longitudinally of the latter. Another Iobject of this invention is to produce 15. a wagon drill of vsimple construction.,'constitut ing an assembly which is strong, dura-ble and eflicient. Other objects and advantages more -or less an cillary to the foregoing reside in’ the.v specific -con 20 struction and aggroupment of the elements peculiar to this structure, as become ap parent from .a more ycomplete examinationl of this specification.

In this illustrative construction, there is shown 50 a carrying ,frame I5 having wheels IB, I1 and I8 rotatably 4secured thereto by which the fra-meis supported. ' The frame ‘ I5 includes two side members I9 and 20 having'thei-r rea-r end‘por tion united by a bracket 2| `carrying-the wheel 5.5. I8. The front .end portion of ~the Imembers. I9 andf2IJ; are-„maintained-iin:spaced relations, and thereby constitute the open> front end of the frame, the -purpose vof `which will be Aexplained hereinafter;y -'I'othe inner ‘wall’ =of each of the side lmembers I9 .and 2.0 there is secured vby bolts 22 :an annular member or `>track v23,-which is lo cated close to the ifront end yof the side member and disposed vertically toextend aboveand :be low the esame. The peripheral wall 24 of each track- 23 is provided with a vrelaitvely narrow 1p ridgel 2-5 having :teeth '26 -out thereon. This pe riphera-l wallf"has‘side walls> 21'-and 28 extending inwardly therefrom, thus constituting an Iannu. lai` track or `guide of substantially -U shaped crosssecti-on having a bottom -wall 29.l The bolts 1:5 2.2" extend through the :side wa-ll 28 yand the cor responding side 'member of the supporting frame I5 to receive the nutsA 3.0„ vby which the track is rigidly `rsecured to 'the frame. ~-lilxtending from -one to the other track 23, 2O there is a tubularwcrossmember 3| having »each ' end portion thereof formed with a -verticalwa-ll 32 «,dependingftherefrom. 'I‘he wall .32 is exter nally machined> to provide two ‘parallel arcuated surfaces> 3,3A and l34, theviîormer slidably engag ingrl the inner portion of the track >peripheral wall 24, while-.the Ilatter- is slidably engaging the «end of the track side Ywall 21; On its inner side,r the wall 32 is formed with two radially dis posed bosses 35, `each v.having a -bolt .3.6 extending therethrough cooperating with anut 31 .and a clamp-38 for locking lthe cross .member 3l lagainst movement relative to thetracks23. As shown in Fig. 6, «the .clamp 38 is AL shaped and has one end formed with .a .ridge ‘.39 engaging the bottom of the'bos's 35, while the other yend is areuated 35 as at 40 in Fig. 8, .for Aengagement with the ar cuated bottom Wall 29 of the track 23. 'I'he wall of the .ola-mp leading from the arcuated end 40 is also in engagement with the side wall 21 of the track ‘2.3 to. prevent the spreading of the 40 side members I9 .an'd‘2ll of the carrying frame I5. Longitudinally Vdisposed through the tubular cross member 3|, there is a shaft 4I having each end-supported within a bearing '42' formed in a _ cap 43 secured to each end of the cross mem- 45 ber by bolts 44. To each end portion of the shaft’ 4I is vkeyed a gear or pinion 45 meshing with thefteeth 26 -of 4the corresponding'track 23. Intermediate its ends, the cross >member 3I is formed with a -rtransversally disposed `boss 46, 50 having an aperture “extending therethrough and'ada-pted to rotatably accommodate a worm 48. Each end of the aperture -41 is threaded to receive a Anut 4'9 through’which extends the re duced correspondingxend .of the worm, which is 55 2 2,135,769 shaped as at 50 to accommodate a handle 5| by which the worm may be rotated. The worm 48 is in constant operative engagement with the teeth of a worm gear 52 keyed on the shaft 4| . Pivotally secured to the cross member 3| by tended to be restrictive or confining, and it is to be further understood that the mechanism herein described may well be used in connection with other types of rock drills or rock drill guid ing frames without departing from the scope and a clamp 53, there is an elongateddrill guiding frame 54 having a drilling motor 55 slidable spirit of the invention as herein claimed. thereon. 1. In a portable drilling rig, the combination with a substantially horizontal wheel supported In this illustrative construction, the elongated frame 54 has a feeding mechanism 10 therein operatively associated with the drilling motor for imparting forward or backward feed ing movement thereto. " ' I claim: carrying frame, stationary tracks carried by said 10 frame in perpendicular relation therewith, a member carried by said tracks independently of said >carrying frame for guided movement on said Pivotally secured to the drill guiding frame 54' by a clamp 56, there is one endof a jack„5'|, tracks, a drill detachably secured to said mem 15 which has its other end pivotally~ ‘connectedl to c ber, said tracks extending longitudinally of said 15 the supporting frame I5. By operating the jack carrying frame and from above to below the 51, pivotal movement is imparted to the drill latter to enable the adjustment of the drill into guiding frame, which may `>thereby be moved: various drilling positions longitudinally of said from horizontal to vertical position relative to frame. above or below the latter due to the move 20 the carrying frame |5. ment of said member on said tracks, and means 20 Referring to the modification shown in Fig.'10, for’establishin'g a rigid connection between said it will >be seen that the'mechanism shown- there in is substantially the same as that previously member and frame in any drilling position as sumed by `said drill by virtue "of the movement described.- In the former the tracks or guides of said member on said tracks. 25 Ei8‘areY of greater diameter than ltheV tracks 23 ofv the latter, and are located to extendrcon siderably higher above the frame 59, which cor respond to the carryingframe l5. On the cross member 60, which is a replica of the cross> mem 30 ber 3|, is pivotally mounted a clamp 6|, which in turn is adapted to receive the center housing 52 of a` drill guiding frame 63. kThis housing is mounted within the clamp 6| in a manner permitting the pivotal movement of the drill 35 guiding frame on an axis normal to the longi tudinal center axis of Vthe cross member 60. Since the connection between the cross mem berûl) and drill guiding frame 63 does not form a part of this invention, and that >_the construc 40 tion shown in Figli) is only a modified appli cationof the invention, no further description is thought necessary. ~ ' i " ` ’ ' ' I-n the operation of the mechanism, when the worm 48 is rotated through the'crank handle 45 5|, rotation is imparted'to the worm gear 52, thus -imparting rotation to the pinions 45 through the shaft 4|. The pinions V«l5 engaging the teeth 26 of the circular tracks 23, will cause the tubu larcross member 3| to travel on the tracks in 50 a circular >path passing between the two side members I9 and _28. Due to the movement of the tubular cross member 3|, it`will be under stood that the drill guiding frame,- together with the drillv 55 therein, may be elevated or low 55 ered with respect to the carrying frame, and be adjusted longitudinally of Vthe latter. ,Due to the movement of the cross member 3|, and the pivotal connection of the'drill guiding frame therewith, the drill 55 may be moved in various 60 drilling positions, above or below the carrying frame, while one end of the drill guiding frame is movable through the open end of the carrying frame. . The cross member 3| may be locked against 65 movement relative to the carrying frame in any position possible Aby virtue of its travel on the arcuated tracks or guides 23, by tightening the nuts 3l cooperating with the bolts 36, for caus ing the clamping engagement of the-arcuated 70 end wall 40 of the clamps 38 withA the bottom wall 29 of the tracks 23. `1 < , . , , Although the foregoing description is neces sarily of a detailed character in order to com pletely set forth the invention, it is to be un 75l derstood that the specific terminologyis not in 2.
