UNITED PATENT ROBERT M. DOWNIE, Oi BEAVER FALLS, PENNSYLVANIA, ASSIGNOR TO THE KEYSTONE DRILLER COMPANY, OF BEAVER FALLS, SYLVANIA.

PENNSYLVANIA, A CORPORATION OF PENN- DRILLING-MACHINE.

Application filed December 26, 1905.

To all whom it may concern:

Be it known that I, ROBERT M. DowNm, a citizen of the rlnited States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented a new and useful Drilling-Machine, of which the following is a specification.

The present invention is more particularly intended for drilling large holes for hydraulic elevators, though not necessarily limited to this use. The necessities of that particular kind of work require a machine at once very strong and combined into the smallest possible compass, so that it may be taken into cellars of buildings or narrow alleys, and it must also be constructed so that it will operate the drilling cable either in a perpendicular direction or horizontally For instance, in case it is impossible to place the drilling machine close beside the spot where the hole is to be drilled, the practice is to place the machine in an adjacent street or yard area and carry the drilling cable horizontally from the machine into the elevator shaft, thence up the same over the crown pulley and down to the well.

The principal object of this invention is to provide a machine having all these essential features, namely, compactness and strength, as well as an adapt-ability for operation either with a perpendicular or a horizontal pull of the drilling cable.

An embodiment of the invention, that is at present considered the preferable one, is Ellus' rated in the accompanying drawings, and (l scribed in the following specification. 43in inspection of the claims will clearly indicate that said invention is not limited to this disclosure.

In the drawings: Figure l is a side elevation of the machine when arranged for imparting a horizontal spudding action to the cable. Fig. Qis a similar view, showing the machine converted into a vertical spudding apparatus. Fig. 3 is a top plan view of the arrangement disclosed in Fig. 2. Fig. 4c is an end elevation of the same. Fig. is a detail side elevation illustrating the connection between the driving means and horizontal spudding device. Fig. 6 is a de tail sectional view showing an arrangement of the reels and the operating mechanism therefor. Fig. 7 is a detail sectional view through one of the rocker arms of the horizontal spudding means. Fig. 8 is a detail Specification of Letters Patent.

view of the means for shifting the gear wheel.

In the embodiment illustrated, a supporting frame is employed, which includes spaced longitudinal sills S, which may be mounted on wheels indicated in dotted lines at 9, said wheels being provided for the purpose of transportation. Over the sills 8 are arranged supporting beams 10, carried by studs 11, secured to the sills 8, one of these studs 11 being set at an inclination, as shown at Fig. and having a curved inner face 12, forming a brake, hereinafter described.

Journaled on the beams 10 is a drive shaft 13, having a pulley 14, around which passes the driving belt 15. Power is imparted to this belt from any suitable source, as, for instance, engine 16 mounted on the rear .end of the frame. A drill cable reel comprising a shaft 1? and heads 18, is journaled on the supporting beams 10, one end of the shaft 17 being mounteo in a cam or eccentric 19 that is journaled in a boxing 20 secured to one of said beams 10. The cam is turned by means of an arm 21 se cured thereto and a link 22 pivoted to the arm. said link extending to one end of the machine, and having a suitable handle 23. The driving shaft 13 carries a grooved friction wheel Q l of comparatively small diameter while the cable reel is provided with a large friction wheel 25, the periphery of which is also grooved. This wheel is so arranged that when the cam 19 is turned in one direction, it will be brought into operative engagement with the wheel 24 of the driving shaft, and when said cam is turned in the opposite direction, it will be moved out of such engagement, and into frictional engagement with the said curved inner face 12 of the stud Il By this means, therefore, the movement of the cable reel is readily controlled. A sand reel 26 has a shaft 2'? journalcd beneath the supporting bee-.1 one end of said shaft being mounted in a cam or eccentric 28, journaled in a boxing 29 secured to the frame. This cam has an arm 30, to which is attached an operating rod 31, terminating in a handle 32, located adjacent to the handle 23. A friction wheel 33 forming a part of said reel, has a grooved periphery, that is movable into and out of coaction with the wheel 24'. of the driving shaft 13. Upon the turning of the cam 28, said periphery is likewise movable out of and into coaction with a brake shoe 34, secured to the frame and arranged outside of said heel. It will thus be apparent that by moving the handle 32 in one direction or the other, the sand reel can be moved into and out of engagement with the wheel 2d of the driving shaft and with the brake shoe, so that the movement of such reel can be readily controlled.

Mounted on one end of the frame are upright spaced guideways formed by sets of spaced standards 35 and in these guideways is mounted a vertically reciprocatory shaft 36, the ends of which project beyond the guidewa-ys, and the standards. A spudding pulley 87 is mounted on the shaft between the gu'ideways. Levers 38 are each fulcrumed at one end upon the cable reel shaft- 17, and pivotally connected to the other end portions of said levers are links 39 having detachable and pivotal connections 40 with the projecting ends of the shaft 36. These levers are provided with longitudinal slots tl, in which are arranged rollers 42, carried by crank pins 43 of crank members ti and 45. T he said crank members are mounted on the ends of a shaft 46, journaled on the supporting bars 10 and extending be tween the standards One of said crank members as at is an arm, while the other is preferably in the form of a gear wheel 4:7 that meshes with a pinion as, carried by the drive shaft 13. This gear wheel is movable into and out of mesh with said pinion, and to this end, the boxing 4-9 for the shaft 46 that is adjacent to the wheel 45 is slidably mounted as shown at 50. A lever journaled on the frame has a. link connection 52 with the slidable boxing, therefore by swinging this lever, the gear wheel can be brought into and out of mesh with the pinion. A holding pin 51 that is adapted to be passed through the lever 51 and any of a series of openings in a quadrant 52 holds the lever in adjusted position.

Journaled on the opposite end portion of the frame to that carrying the vertically movable spudding mechanism above described, is a rock-shaft 58, that is provided with spaced upstanding rocker arms 54-, these rocker arms being each provided with a plurality of recessed seats An axle 56 is arranged to be located in either of the corresponding sets of seats, and is held therein by clips 57 adjustably engaged with the arms. Mounted on the axle 56 between the arms is a substantially horizontally movable spudding pulley 58. One end of the rockshaft is provided with a crank arm 59, having a crank pin 60, and a pitman 61 is arranged to connect this crank pin with the crank arm 4st of the shaft =16. Means are and the associated parts against movement.

iVhile any suitable means may be employed, in the present embodiment, a. brace or holding link 62 is provided, one endof which is secured as shown at 63 to the sill, the other end having an eye 6% arranged to be placed over the adjacent end of the axle 56.

It is thought that the manner in which the machine is used can now be made clear. If the apparatus is to be employed for imparting a horizontal spudding movement to the drill cable, the parts are arranged as disclosed in Fig. l. The drilling cable 65 preferably passes from the underside of the reel underneath and about the Spudding pulley 58, thence in a horizontal direction through the mechanism. The levers 38 are detached from the cranks 4d, and 45, the holding link 62 is detached from the axle 56, and the pitman 61 is connected to the crank sl-.4, and the crank 59. Assuming therefore that the engine is in operation, it will be apparent that when the gears a5 and 48 are thrown into mesh, the crank at. will be rotated and the crank 59 oscillated, thereby etfecting the oscillation of the pulley 58 and securing what may be termed the horizontal spudding action of the cable. If, however, the machine can be placed contiguous to the hole and the cable can be ar- "anged in av substantially vertical direction, then the machine is converted, so that the parts are disposed, as illustrated in Figs. 2, 8 and t, that is to say, the oscillatory pulley 58 is secured against movement by the link 62, the pitman 61 is detached from the crank eta, and the levers 38 are connected to said cranked and to the crank wheel The links 39 are also connected to the vertically movable pulley 87 and the cable still passing about the pulley 58, which new acts merely a guide, is also passed beneath and around the cable sheave 37. Upon the operation of the machine as so arranged, it will be apparent that the drilling cable will be given a vertical movement. It is thought that the operation of the reels will be clearly apparent. Under ordinary condition, the wheel 25 of the drill wheel is in engagement with the brake l2, consequently said reel is held against rotation. If, however, the wheel 25 is moved into engagement with the wheel 24, the reel will be rotated. In like manner, the wheel 33 of the sand reel is ordinarily in engagement with the brake 34-, but when moved out of engagement with the said brake, and into coaction with the wheel 2 it will be revolved to wind thereupon the cable, which is shown in Fig. 2, and is designated 65, said cable preferably passing about a pulley 66 suitably journaled on the frame. It will also be clearly evident to those skilled in the art that the structure disclosed is applicable for use on a single well. Thus for spudding in orstarting the well when the tools are of necessity operating above the surface of the ground, the vertically operating mechanism is employed, and afterward, when the well has been started, the horizontally operating mechanism can be used for finishing it, the latter then being employed in place of the usual walking beam mechanism.

It will thus be seen that a comparatively simple, compact and powerful machine is provided, which can be employed either in horizontal or vertical spudding, and is thus peculiarly useful for drilling the wells or holes for hydraulic elevators, though as already stated, it is not necessarily limited to this use.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein .described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
