To tq-ZZ whom may concern:

Be'itknowntbatLGEoRGnDqDLnY LooMis, ascitizen of; theUnited States, residing at Tiffin,-in the county of Seneca and State of Ohio, 5 have invented a: new and useful Well-DrillingMaehine ofwhi-ch the following is a specification.

. Ihisrin-vention relates to. well-thrilling machinery, and has forits'object to provide a -l compact structure in which the main drivepulley; the main crank, as also the hoistingwheel and brakemechanism; will be mounted upon a single;shaft, thus occupying a minimuni of sp'ac andworking together without theinterve'ntion of'gearing.

v Thein'venti-onconsists, generally stated, of

a mai'n shaft havi'ng'a main drive-pulley fixed theretoand"carrying also a drill and spud operating crank, a brake-drum, and means for communicating motion from the shaft to an adjacent rotatable body, clutching mechanism being also arranged to alternately.

clutch and-release th'e brake-drum and the motion-transmitting means with respect to the shaftp jiAdjacen't the main shaft and adapted to receive motion therefrom are the usual rope d-rum and sand-drum, as also a derrick, in which is mounted a walking-beam or a pulley to receive the spudding-rope. 0 While there is shown a motor in the form of an engine, it will be readily understood from i the following description that any other power may be employed.

In the drawings forminga portion of this 3 5 specification, and in which similar numerals of reference designate corresponding parts, Figure 1 is a side elevation showing a+ ma- "hine embodying this invention. Fig. 2 is a plan View of the machine. Fig. 3 is r erti cal section on line 3 3 of Fig, 2 and sh. win,

portions in elevation.

Referring now to the drawings, ll employ a frame which comprises side sills 5 and 6, havingend cross-beams 7 and 8, connected 5 with which latter is an intermediate beam 9. Upon the sills 5 and 6 and at one end thereof are uprights 10, and in the rear thereof are additional uprights 11, the uprights of the sill 5haviug a connection 12 above and parallel with that sill, while the uprights of the sill6 have a connection 13 above and parallel with that sill. A beam or connection 15 is supportedabove and parallel with the intermediate sill 9, said connections 12, 13,

and 15 lying in a common horizontal plane.

Upon the connections or beams 13 and 15 are fixed bearings 16 and 17,respectively, in which is journaled the main drive-shaft 18, having at one end and between the beams 12 and 15 a crank 19, provided with a wrist-pin 20,

adapted for connection with a pitman 21,

pivotally connected with one end of a walking-beam 22, rockingly journaled upon a.

derrick 23, supported upon the' front end of the frame of the machine. At the opposite end of the shaft 18and, exteriorlyj of the inclosure of the sills is a main drive-pulley 24, from which the mechanism may be driven.-

Upon the shaft 18 and adjacentuthe beam 13 is loosely mounted a gear-wheel 27, bolted to the inner face of which is a brake-drum ring.

28, a brake-band 29 lying in engagemen'twith:

theouter periphery of said drum and having one end fixed to a cross-piece 30 intermediate.

the beams 13 and 15 and the other end pivotally connected with the end 32 0f a bellcrank lever, the operating-handle 33 of which extends forwardly and beyond the front end The inner face of the gear.

of the machine. 27 within the inclosure of the ring 28 forms a clutch element and for this purpose is provided with a recess 33, which is adapted to:

receive at times the end of a lever 34, pivoted to cars 35, carried by a hub 36, which is fixed upon the shaft 18. .A collar 34 upon the shaft intermediate the gear 27 and the bearing 16 prevents lateral displacement of the gear 27 in one direction, while the hub I 36 prevents similar displacement in the op posite direction.

In order to engage and disengage the lever 34 with respect to the recess 33, said lever has its outer end turned downwardly and in the path of a second hub 38, loosely mounted upon the shaft 18 and having its end adjacent said lever formed frusto-coni'cal. This hub 38 has a peripheral groove 39, in which is seated a ring 40 upon the end of alever 41, which extends forwardly and beyond the front end of the machine. Thus as the hub 381s moved to the right of Fig. 3 it will press the adjacent end of the lever 34 outwardly and will move the opposite end of said lever to engage the recess 33 in the gear 27. 1 Also it will be'seen ICO that if the lever be in, engagement with the gear 27 and be then removed therefrom after contributing motion to said gear if it be then desired to retard or stop the movement of the gear such operation may be accomplished by operation of the lever 33 to draw the brakeband 29 tightly against the brake-drum.

'Meshing with the gear 27 isa pinion 40,

which in turn meshes with a gear 41Fupon mit motion thereoif tothe spudding-drum to cause it to wind in the rope. 0n the other hand, if it is desired topay out the rope such paying out may be accomplishedwithoutstopping the machinery and may be regulated from the lever 33'and tir'ely.

.It will be noted that the several levers-for operatingthe different parts of the mechanism project ou'twardlyof the forward end of the machine and are thus in a position 'tobe manipulated by the operator standing atthe drill-rope. There is shown in the present instance also a sand-drum 4-5, which is adapted for the usual purposeot' a drum of this nature and has a friction-wheel 46 at one end which is adapted to be brought into engagement with the adjacent periphery of the driv-' ing-pulley 24 when it is desired to operate the rope carried thereby. v

It will be seen from the foregoing description that the presentinventio'n accomplishes in an eflicient manner the objects for which I it is designed, that the working parts are compact, and that the mechanism is simple in the extreme.

It is apparent that, if desired, the diameters of the gears 27 and 41 may be increased may be stopped .en-

to that extent sufiicient to permit them to mutually engage, thus eliminating the pinion 40; also, that various other modifications may be substituted, and that any proportions may be observed and material used without departing from the spirit of the invention.

Having thus described the invention, what is claimed is-,

1. In a well-drilling machine, the combination-of a bull-wheel shaft having a pulley 24 and a crank, said pulley and said-crank being 'fixed to said shaft, a walking-beam, a pitman to connect the latter to the wrist of said crank, whereby the walking-beam may be driven directly from said bull-wheel shaft, a gear 27 loose on said 1 bull-wheel shaft, a brake for said gear to arrest rotation thereof,'a drillrope reel drivenby said gear,a clutchto lock said gear to said bullewheel shaft, and a sandrope reel having a shiftable pulley '46 adapted to be'engaged with and driven by said pulley 24, substantially as described. .7

2. In a well-drilling machine, the com bination of a bull-wheel shaft, a pulley 24 and a crank fixed to said shaft, a gear 2710039 11 said shaft, and having a notch 33", said shaft having, a fixed hub 36,a shiftable hub 38,. .7
