SETH Il. POWERS, OF STANBERRY, MISSOURI.

SPECIFICATION forming part of Letters Patent No. 738,843, dated September 15, 1903. Application filed January 3], 1903. Serial No. 141,307. (No model.)

.To @ZZ whom, it may concern:

Be it known that I, SETH H. PowERs, a citizenof theUnited States, residing at Stanberry, in the county of Gentry and State of Missouri, have invented a new and useful Combined Well-Boring and'Rock-Drilling Machine, of which the following is a specification.

My invention'relatcs to a combined boring and drilling machine, and has for its object to provide a simple, compact, and efficient construction and arrangement of parts capable, by the minimum adjustment, of performing the functions of either a boring or a drilling machine, inclusive of those necessary for carrying and emptying an auger after it has become lledwith borings, and also to provide efficient means for controlling the elevation and lowering of the auger and drilltools, either manually or mechanically.

'A further and important object of the invention is to provide an improved spudding mechanism capable of imparting the desired reciprocatory movement to the drill-tools, and in connection therewith. to provide efficient means for varying the stroke of the tools, this portion of the mechanism being so constructed as to allow the gradual feeding of the drill rope or cable.

A further object of the invention is to provide simple and efficient means for communieating motion to the spudding and other devices, and also to communicate rotary motion to the supports for the drilling mechanism, whereby rotary motion is communicated to the drill during the spudding operation.,

Further objects and advantages of this invention will appear in the following description and the novel features thereotwill be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a combined drilling and boring machine constructed in accordance with my invention, the parts being adjusted for drilling. Fig. 2 is a partial side view of the same. Fig. 3 is an end view. Fig. 4 is a horizontal section on the plane indicated by the line 4 4 of Fig. 2. Fig. 5 is a detail view of a portion of the master-gear or endless rack. Fig. 6 is a detail view in perspective of one of the brake devices. Fig. 7 is a similar view of an auger-holding clamp-jaw. Fig. 8 is a detail view of the clutch employed for connecting the members of the drive-shaft. Fig. 9 is a similar view of the spudding drum and attachments. Fig. 10 is a similar view of the lock for the bull-wheel gear. Fig. 11 is a similar view of the locking means for the manuallyoperated bullwheel-rotating devices. Figs. 9, 9b, and 9 are detail views, respectively, of the spudding drum and its attachments separated.

Similar numerals of reference indicate corresponding parts in all the figures of thed rawings.

The supporting-frame of the apparatus em-` bodying my invention preferably consists of a portable base having parallel side beams 1, terminally supported by wheeled trucks and transverse connecting-bars 2, and supported by this base is a turn-table or platform 3,

provided with carrier wheels or .rollers 4 to traverse a circular track 5, consisting of an -internal liange formed on a horizontal master-gear G, which is bolted permanently to the base. The turn-table or platform is provided with a central opening 7, through which the drilling and boring operations are performed. Rising from the turn-table is a derrick or frame, which preferably includes front and rear pairs of transversely-opposite upwardlyconvergent uprights S and 9, connected at their upper ends by a cross-bar 10, said front and rear uprights being preferably connected in pairs by longitudinal horizontal braces 11, upon which are stepped the lower ends of standards, each of which is of sectional construction and comprises an upper movable member 12 and a lower fixed member 13. The sections of the standards are secured together by mating bracket-plates 14, having contiguous ears 15, connected by bolts. The standards are connected at their upper ends by a cross-piece 16 and at an intermediate point by a cross-rod 17, upon which is mounted a pulley or guide 1S. ln addition to this. main frame I also employ an auxiliary side frame, including uprights 19, connected with the main frame by means of braces 20, and at the opposite side ofthe main `frame I have also shown a secondary upright 21, suitably braced and connected with the contiguous main upright 8. It will be understood, however, that the specific .arrangement of the auxiliary framing members may be varied to suit the ICQ 1 adjustment upon the shaft member 23h.

the construction illustrated the movable oroperative parts which are to be supported thereby, but that the described construction has been designed to accomplish the desired objects with the minimum expenditure of material and in order to secure a desirable compactness of structure. K

Extending transversely of the frame and mounted in suitable bearings thereon is a main shaft 22, adapted to receive motion from a driving-shaft 23, which is 'mounted vertically upon the frame and is provided with a bevel-gear 24 to mesh with a corresponding gear 25 on the main shaft. This driving-shaft is of sectional construction, with its lower member 23n carrying a pinion 26, which is permanently in mesh with the peripheral teeth of the master-gear 6 for continuous operation during the rotary movement of the turn-table or platform, the latter being actuated by any suitable means, as by horse-power, for which purpose it is provided with a sweep 27 and other means for connectingdraft-animals thereto. In practice I also prefer to employ an idle pinion 26n for permanent engagement with the master-gear and having its spindle suitably mounted in bearings on the turn-table or platform at a point diametrically opposite to the operatin gpinion 26. The upper member 23b of the driving-shaft carries the above-described bevelgear 24, and in order that the driving-shaft members may be vconnected for the communication of motion from the lower member to the upper member I provide a clutch consisting of an axially-fixed member 28 on the shaft member 23 and an axially-movable clutch member 29 'feathered or otherwise fitted for In adjustable clutch member 29 is fitted upon a squared portion of the shaft member 23b and is connected by a link 30 with a hand-lever vice 32, with which the hand-lever may be engaged when the clutch members are disengaged.

Also mounted in suitable bearings upon the frame parallel with the main shaft is a counter-shaft 33, operatively geared to the main shaft,as by a sprocket-chain 34, traversingl sprocket- wheels 35 and 36, secured, respectively, to the main and counter shafts. This counter-shaft forms one member of the spudding apparatus and carries a spudding-drum n 37, consisting of parallel disks provided with traversed by'a drill-rope, as hereinafter fully explained. Secured to one or both sides of the spudding-drum is a cam 42, forming one member of a clutch, whereby motion is communicated from the counter-shaft 33 to the drum, the latter being loosely mounted upon its shaft for alternate revoluble movement in opposite directions. The other clutch member consists of a clutch-arm 43, pivotally mounted upon a bracket-arm 44, which lis fixed to said shaft, the clutch-arm being preferably provided with a terminal pin 45, carrying an antifriction-roll 46 or the equivalent thereof for contact with the face of the clutch member 42. The bracket-arm 44 is preferably bifurcated, as shown, to receive the clutcharm, and the latter is extended beyond its fulcrum-point to form atrip-arm 47, adapted for contact with the platform or other fixed smooth-surfaced portion of the mechanism in order to disengage the shaft clutch member 43 from the drum clutch member 42 and allow the return movement of the drum after the latter has completeda predetermined angular movement in a forward direction. The clutch-arm is yieldingly held in its normal position by means of an actuating-spring 48, coiled upon a guide-pin 49, which. extends through a guide-opening 50 in thetrip-arm,the opposite end of said guide-pin being secured to a projecting shouldered portion 51 of the bracket-arm. The solid-line arrow in Fig. 9 indicates the direction of forward rotation of the clutch-arm-carrying devices and the dotted arrow in the same figure the return movement of the drum after the release of the clutch member 42 by the displacement of the clutch-arm.

The main drill-rope 52 extends from a drum or bull-wheel 53 to and over a pulley 54, located near the upper end of the derrick, thence to the running or movable pulley 4l, again upwardly to the top of the derrick, and over a second pulley 55, and is attached to the upper end of a drill-tool 56 of any suitable or preferred construction, and it will be seen that the continuous rotation of the countershaft 33 during the revolution of the turntable or platform will communicate motion from the clutch-arm 43 to the spudding-drum and carry the same around, thereby drawing upon the chain 40 and elevating the drill-tools untilthe trip-arm comes in contact with a fixed object, when the release of the drum will allow the drill-tools to drop. By placing the pin 39 in different alined openings of the spudding-drum the length of stroke of the running pulley 4l before the release of the drum from the clutch-arm may be varied to suit the conditions under which the machine is operated. V

In order to control the operations of the bullwheel and provide for the elevation of the drill-tools by the winding of the drill rope or cable 52, I employ a gear 57, fixed to the spindle 58 of the bull-wheel, and a shifting pinion 59, mounted upon the feathered or squared portion of the main shaft and adapted to be thrown into or out of the plane of the gear 57 in order to communicate motion to the bullwheel or allow the free rotation thereof, as may be preferred. When it is desired to ele- IOC IIO

vate the drill-tools by the winding of the cable 52 upon the drum or bull-wheel, the spudding device is first disconnected from the main shaft or is thrown out of gear in any suitable manner, as by the removal of the sprocket-chain 34, and the pinion 59 is moved into engagement with the gear 57 to communicate motion to the drum-shaft 58. When it is desired to relower the tools, the members of the driving-shaft clutch should be disengaged to permit the opposite rotary movement of the main shaft, and the rapidity of descent of the tools may be controlled by means of a brake fitted upon the main shaft and consisting of a drum GO and opposite brake-shoes Gl. and 612, properly constructed to fit opposite sides of the drum and carried,respectively, by a pivotal arm 63 and a brake-lever 64, which are hinged together at their remote ends, as shown at 65. It is obvious that by depressing the brake-lever or moving its free end toward the pivotal arm 63 the brake-shoes will be forced into Contact with the surface of the drum to impede to a greater or less extent the rotary movement of the shaft. It is also desirable for the manipulation of smaller tools or for raising and lowering the tools short distances to employ manual means requiring no particular adjustment of the parts, and hence I employ a crank-shaft 66, suitably mounted upon the frame and having a terminal key-seat to receive a crank-arm 67, an operatinggear 68, carried by said crankshaft, and a gear 69, carried by the bull-wheel shaft 58. The gears 68 and 69 may be connected for operation to communicate motion from the crank-shaft to the-bull-wheel shaft by means of an intermediate pinion 7 O, loosely fitted upon the main shaft 22 for movement into and out of the plane of said gears. This pinion '70 may be locked at any desired adjustment to correspondingly hold the bullwheel by means of a latch 71, mounted to slide in a suitable guide 7 2 on the frame and having an operating hand-lever 7 3, said latch being adapted to engage between the teeth of the pinion; but as a means of locking the bullwheel against rotary motion and for facilitating the gradual feeding thereof during the drilling or spudding operation I employ, in connection with the gear G9, a locking device, including' a bolt 74:, mounted for movement radially with relation to said gear and springactuated, as by a coil-spring 7 5,arran ged upon a guide-pin 7 (5, said bolt having one extremity arranged in operative relation with the teeth of the gear G9 and having the other end outwardly turned to form a step 77, upon which the foot of the operator may be arranged to disengage the bolt from the wheel. lIn connection with the bolt I employ a latchl 7 S, adapted to hold the bolt in its inoperative position and having a terminal.shoulder 7 f) to bear upon the foot-rest 77. i

In connection with the abovedescribed mechanism I also preferably employ an auX- iliary cable 80, adapted for lowering auxiliary or additional lengths of drill-tools into 'the hole for connection with those already in operation and also for elevating an auger preparatory to the emptying thereof, and hence I have illustrated a drum Si, of which the spindle82 is mounted in suitable bearings on the frame and carries a shifting gear 83, mounted upon a feathered or squared portion of the spindle and adapted for movement into and out of the plane of a gear Si, carried by the main shaft. This drum or auxiliary bull-wheel shaft is fitted with a brake device having a lever 645 and constructed identically as hereinbefore described in connection with the brake upon the main shaft. Said lever is used in connection with a clip 85, whereby the auxiliary drum' may be locked against rotation during the operation of the drilling mechanism. rope or cable extends over the hereinbeforedescribed pulley 1S, mounted uponthe trans- The auxiliary y verse rod 17 of the derrick, and in the draw- A ings it is shown attached to a drill-rod sec-A tion 56% The extremity of the shaft S2 is also constructed to form a wrench-seat in order that the auxiliary drum may be manually operated.

It will be seen from the foregoing description that from the main shaft, whichis actuated directly bya driving-shaft, of which one member is in permanent mesh with the fixed master-gear, I am enabled to communicate motion simultaneously or independently to either the spudding-drum shaft or the several drum-shafts and that by means of the shifting devices referred to it is possible to change the connection of the main shaft with the other members without loss of time or to wholly disconnect the main shaft from the other parts of the device in order to check the motion thereof or to release said other members for the paying out of the connected cables.

In addition to the parts already described, however, I have provided simple means for adapting my machine for boring, and in this connection I provide an auger holder or clamp 86, arranged for vertical movement upon the frame supported by the platform or turn-table, but designed to engage the auger and communicate motion thereto from the rotary platform. In the construction disclosed this auger holder or clamp, which is illustrated in detail in Fig. 7, consists of cooperating correspondingly-constructed members S6 and '86", having longitudinal slots S7 and interlocking inner ends or jaws adapted to engage the auger-shank 88. Said slots .receive vertical guides 89, extending upwardly from the platform to horizontal braces 90, connecting the front and rear uprights 8 and 9 of the Yderrick, and the holder members are thereby adapted for either longitudinal or vertical movement to suit the movements of the auger, but are held from lateral movement, whereby as the platform rotates the jaws communicate motion to the au ger and accomplish IIOv the boring operation. The specific construction of holderjaws illustrated in the drawings embodies a tongue 91 on each member for engagement with a seat or loop 92 on lthe other member, the tongue and seat or loop of each member being exposed perpendicularly to each other, whereby when the jaws of the two members are connected they form an angular opening in which the shank of the auger is held from rotation.

It will be understood that any ordinary construction of auger maybe used in connection with the apparatus, and during the boring operation the superstructure of the derrick, including the 'standard members l2 and the pulleys 1S, 54:, and 5.5, may be removed.

The means for raising the auger when filled consists of a crane 93, mounted at its lower end in a suitable socket in the platform and at its upper end in a bearing in a bracket 94, extending horizontally from the main or lower portion of the derrick-frame. In the construction illustrated this bracket consists of angularly-disposed rods having registering loops at their outer ends to form the abovementioned bearing and provided at their inner ends with hooks 95, which engage eyes 96 in arms 97, projecting rearwardly from the derrick-frame. It will be understood that this crane may be readily dismounted or replaced, according to whether the machine is to be used for boring or drilling, and in Fig. l I have shown suspended thereon an auger 98, as seen when withdrawn from the hole and swung outward beyond the platform for emptying. It will be understood that the auxiliary cable SO may be employed for this purpose, as indicated by the dotted lines in Fig. l, the auger being elevated by means of said cable and engaged with the terminal hook 99 of the crane, after which the latter is swung, as indicated in said Fig. I, to discharge the borings.

From the above description it will be seen that the machine embodying my invention is compact and includes all of the mechanism necessary for either boring' or drilling and that the adjustment of the members to suit it for either purpose may be accomplished with the minimum loss of time and exertion upon the part of the operator, whereby the machine may be controlled by the aid of the minimum number of attendants, and, furthermore, that in practice various changes in the form, proportion, and the minor details of construction may be resorted to Without departing' from the spirit or sacrificing any of the advantages of this invention.
