To all whom it may concern:

Be it known that I, PHILANDER B. FREE- MAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in WVell-Drilling Machines, of which the following is a specification.

, My invention relates, in general, to welldrilling machines adapted for drilling deep wells by means of a suspended drilling-tool which is alternately raised and allowed to fall so as to strike thesoil, and thereby sink the well.

It also relates, in particular, to machines of 4 the above class in which the drilling-tool can be suspended for spndding from the free end of a rope or cable which extends upwardly to an overhead or elevated support, usually a pulley, over which it'is reeved, and thence to a spndding vibratory member which engages and operates it in a way to cause the portion thereof between such vibratory member andthe overhead pulley to be alternately drawn in a direction away from the latter and allowed to return in a direction toward the same, so. as to thereby raise and lower the drilling tool, in which said machine the tool can also be alternately suspended for drilling proper from a substantially vertically reciprocating or vibratory drilling member arranged in position over or above the well and connected with the tool so as to impart thereto a reciprocal movement substantially identical with its own action.

Prominent objects of my invention are to arrange for the slow-rise and quick drop of the drilling-tool both in spndding and in drilling proper; to provide simple, effective, and practical mechanism for such purpose; to arrange for the easy raising and lowering, each in a single operation and by a single operator standing upon the ground, of the mast or derrick upon which the overhead or elevated pulley is usually mounted, and to provide other novel and useful features tending to increase the eificiency of deep-drilling wellmachines. 1

In a well-machine characterized by my inventi on the spuddin g vibratory member when the drilling-tool. is suspended from the free end of the rope or cable and the'latter is operated by such member-or,

inother words,

when the machine is in condition for spudding-ecan be given a ditferentially-reciprocating movement-that is to say, a movement involv ng alternately and relatively fast and slow reciprocatory strokes or impulses-in a way to cause the portion of the rope or cable between such spndding member and the overhead pulley to slowly recede from and rapidly approach the latter, and also the drilling vibratory member, alternately and when the drilling-tool is suspended therefrom--or, in other words, when the machine is in condition for drilling-can be given a differentially-reciprocating movement in a way to cause its slow elevation and quick descent.

As a result, whether the machine be spudding or drilling proper the drilling-tool will be given a relatively slow rise and quick drop.

lnthe machine hereinafter described for carrying out my invention the rope or cable from whose free end the tool can be suspended is extended downwardly from the overhead pulley and hasjts other end portion coiled about and in effect held by a rotary reel or drum mounted upon the framework of the machine. In spndding this portion of the rope or cable between the reel or drum and the overhead pulley has a sliding connection with the vibratory spndding member in such Way that it is alternately slowly flexed or drawn aside and quickly allowed to return to substantially its former position thereby. ,This alternate relatively slow flexure and rapid return to position of such actuated portion of the rope or cable causes the movement of the portion thereof between the spndding vibratory member and the overhead pulle'y alter= nately slowly away from and quickly toward the latter.

7 Both the differentially-reciprocating spndding and drilling vibratory members are carried by a single longitudinally-extending pivotally-connected vertically-swinging vibratory or swinging frame, which can be differentially vibrated or swung about its pivotallyconnected end either with a relativelyslow downstroke and quick upstroke or with a rela-' too , longitudinally in the o rocating mechanism operating such illustrated in Fig. tion taken on line tively slow upstroke In t] slow rise and rapid descent of the tool. Also when itis desired to drill and themachine is in spudding condition the a relatively slow upstroke and quick downstrokc, and when so operated it will cause-the relatively s'lowrise and rapid descent of the drilling'member and therefore of the drilling-tool.-

The verticallywibrating swinging frame is differential] y vibrated alternately in one and the other. of the diiferentially-vibrating reversible actuating mechanism. This mechanism comprises a couple of vertically-swingin g, longitudinallyarranged, and pivotally-connected swinging beams provided with longitudinal guideways and a couple of vertically-rotating rotary cranks rotating in unison and having their wrist-pins working in the guideways formed swinging beams, and thereby elevating and lowering the latter either with a relatively quick rise and slow drop, or vice versa, according to their direction of rotation. "For other novel features and also for matters of detail in the particular form of machine illu trated reference is made to the accompanying drawings, in which- Figures 1 and 2 are side elevations of a well: drilling machine embodying my invention and having its operating-mechanism arranged forspuddin g and drilling, respectively. Fig. 3 is a side elevation of a portion of the same, particularly illustrating the vertically-swinging frame carrying both the spuddin g and drilling members and the diiferentially-recipframe. the portion of the machine 3. Fig. 5 is a vertical secwpc in Fig. 3. Figs. 6 and 7 are vertical sectional views of details of construction;

Fig. 4 is a plan of In spudding, Fig. 1, the drill 1 issuspended,"

usually through the medium of a drill-rod 3, from the freeend of a rope or cable 2, which latter is extended upwardly. to and isreeved about an elevated or overhead pulley 4 at the top of a mast C, which rises from the rear end of the body-frame A of the machine.

From the overhead pulley 4 the rope or cable 2 isextended downwardlyand has itsother end held or tied-as, for example, by being coiled upon a rotary drum or reel B. .lntermediate of the overhead pulley 4 and the reel or drum B the rope or cable is looped forwardly and reeved about a sheave or pulley 6 on a transverse rotary shaft 7, mounted near the forward end of the machine in bearrapid 1 position of the actuated portion of the rope or cable and the consequent relatively swinging beam can be diiferentlally swung with tially reciprocating twoways mentioned by a thus suspended as the sheave or pulley 5, which'has a differen'-- tially-reciprocating movement involving alternately and relatively slow down and quick up strokes or impulses.

In drilling proper, Fig. 2, the rope or cable a is desirably disengaged from the differenspudding-pulley-5 and the drilling-tool-l is detached from the free end of such rope or cable and is suspended from a substantially vertically-reciprocating drilling member, such as a hook, which also reciprocates differentially, but with relatively slow upand quick down strokes, an'dfso alternately slowly elevates and quickly lowers the drilling-tool 1. The drilling-tool 1 is usually from the drilling member through the medium of a temper-screw 10, held in a fork-shaped holder 10 The spudding vibratory member, such as the pulley 5, and the substantially "vertically reciprocating drilling member, such as'the hook 9,,could be mounted ina ny suitable manner, and they could be operated in any desired way, so as to cause alternately and relatively slow down and quick up strokes or impulses on the part of the former and relatively slow up and quick down strokes on the part of the latter. However, as a preferred arrangement and matter of further improvement both "are mounted upon or carried by a vertically-vibratory frame which can be differentially re' ciprocated either with a relatively slow descent and quick rise,

machine is in spudding condition, or with a relativelyslow rise and quick drop, so as to properly actuate the drilling member when the machine is in drilling condition.

The vibratory frame shown comprises a couple of connected swinging beams D D,;extending longitudinally and substantially the length of the machine-frame A and having their forward ends pivotall'y'conuected to the forward end of the machine-frame rear ends projecting to the rear of the rear end of the same, so as to allow freedom of suspension ing position, a forward cross-beam E, which extends between and is secured to the swing; ing beams D D forward of the rear ends and has the spudding-pulley 5 secured to it'at its longitudinal middle,,a nd a'rearcross-beam 8, attached to the-rearends of the beams D D and carrying the hook 9 at its longitudinal middle.

In spudding the hook 9 can be retracted from position immediately above the well, so

so as to properly actu-' 'ate the spudding vibratory member when the and their of the drilling-tool when in drill as to prevent its interference with the portion V p of the rope or cable 2 depending from the overhead pulley 4, by longitudinally and forwardly adjusting the Vibratory frame carrying such hook, as best shown in Fig. 1. This can be done by turning a transverse rockshaft 12, Fig. 4, mounted in bearings attached to uprights a a atthe forward end of the frame A, so as to draw upwardly and rearing-tool suspended from the hook 9, the lever l 13 can be swung upwardly to its uppermostposition, as shown in Fig. 3, so as toproject such hook 9 forwardly into position over the well and can be lockedinsuch position upon the segment 14. In spudding, also, if desired, the hook 9 can be further retracted by turn- I ing the rearmost cross-beam 8, carrying the drilling-hook 9, about its lower forward edge as an axis by means of a hinge connection which it has with the beams D D, so as to in effect place it forward of its normal position on the latter, or. the book 9 can be suitably retracted by simply turning the beam 8 about its hinge or pivotal'con'nection with the beams DD without longitudinally and forwardly adjusting the latter.

The vibratory frame carrying the spuddingpulley 5 and the drilling-hook 9 is desirably immediately actuated by a couple of substantiall y vertically-disposed and vertically-reciprocating links 16 16, having their upper ends pivotally connected with the beams D D, forming a part of such frame, in which way a substantially. vertical reciprocating movement can be transmitted to the free end of the frame, while at the same time the frame can be longitudinally adjusted for the adjustment inposition of the drilling-hook 9 without either interfering with or substantially changing such movement.

The vertically-arranged links 16 16 can be differentially reciprocated either with a relatively slow descent and quick rise for'spudding or with a relatively slow rise and quick descent for drilling by any suitable reversible power-driven actuating mechanism. However, as a preferred arrangement and matter of further improvement they are so operated by the rotation in either one direction or the other of a transversely -disposed reversible crank-shaft 17, carrying a couple of cranks G G and supported by the frame-bars 0!. at The rotation of the cranks G G causes the reciprocation of a couple of guide-blocks 18 18, holding their wrist-pins of a couple of ro tary cranks G G in longitudinal guideways 19 19, formed in acouple of vertically-swinging vibratory or swinging beams F F. The

swinging beams are disposed longitudinally of'the machine in position below the swingingbeams D D of the carrying-frame and have their forward ends pivotally connected to uprights a. at of the machine-frame-and are pivotally connected near their rear ends to the lower ends of the vertically-disposed links 16 16. V v The swingingbeams F F are desirably considerably shorter in length than the swinging beams D D of the carrying-frame, in which way a maximum difference in the relatively slow and rapid strokes of the carrying-frame can be obtained,while at the same time the drilling-hook 9 will deviate but slightly from the vertical in its reciprocation.

The rotary crank-shaft17 is driven from a rotary driving shaft 20, situated forward thereof and journaled in suitable bearings supported by the bars a a, through the medium of suitable power-transmitting connection between such shafts, and it can have its direction of rotation reversed or be stopped at will by means of suitable reversing and stopping mechanism in such power-transmitting connection. The reversing and stopping mechanism shown comprises a large gear 21 on the crank-shaft 17, a lower idle-shaft 23,

mounted in suitable bearings supported by the frame A and provided with a couple of rigidly-attached gears 31 and 22, whereof the latter meshes with the gear 21 on the crankshaft 17, and a couple of rigidly-connected gears 24 and 28, loose on the driving-shaft 20 and respectively provided with clutch-jaws- 25 and 29, adapted, respectively, to engage cooperating clutch- jaws 26 and 30, respectively, keyed to the shaft 20 and formed in the. hub of a belt-pulley 27 on such shaft.

These rigidly-connected gears 24 and 28 can he slid along the shaft 20-as, for example, by a longitudinally-arranged hand-lever 32 engaging their intermediate hub portion and pivotally connected to the machine-frame at 34-so as to cause either the gear 24 to mesh with the gear 21 on the crank-shaft and the clutch-jaws 25 thereof to engage with the cooperating jaws 26 or the gear 28 to mesh with the lower gear 31,and the clutch jaws 29 thereof to engage with the cooperatingjaws'30,Figs. 4 and 5, or both gears 24 and 28 to lie in position between and be disengaged from the gears 21 and 31 and the clutch-jaws 25 and 29 thereof to likewise lie between and be dlSGl]: gaged from the codperating jaws 2G and 30. Assn min g that the driving-shaft 20 is rotated in the direction'indicated by the arrow in Figs. 4 and'5, in the first case the crank-shaft 17 will be rotated in the clockwise direction mentioned as being necessary for spudding, Fig. 1', In the second case it will be rotated in the opposite direction for drilling, Fig. 2, and in the third it will be entirely. disconnected from the driving-shaft 20, and so will not be rotated at all. It is obvious that in place of the two gears 24 and 28 I could employa single gear with like result;

two, chiefly on account of the considerable with the engine H, is mounted upon the for ward end of the machine-frame A, Figs. 3

,and 4, and it is to such end belted to the enby a transversely-arranged rotary shaft 38,. 2'0

gi'ne-shaft H by a belt. (Not shown in the drawings, but understood to be arranged over and between the belt-pulley 27 on the driving-shaft and a similarpulley on the engine-shaft H.)

The reel. B, upon which the rope or cable 2 is wound, is carried by a rotary shaft, which is journaled in bearin gs supported by a couple of horizontal side bars a a". It is controlled supported by'the bars aa through the medium of a couple of pairs of intermeshing gears 36 36and 37 37, respectively, on the reelcarrying shaft and the controlling-shaft 38. The reel-controlling shaft .38 can be rapidly rotated by power in a way to coil the'rope or cable 2-upon the reel B, and thereby rapidly elevate the drilling-tool 1, by swinging a longitudinally-extending hand-lever 52, which is forward end gitudinally exten pivotally connected to the frameA at 53, in a way to cause a friction-cone 48, engaged by its forward end andslidable upon the drivjug-shaft 20, to engage and rotate a coeperating friction-'cup49, securedto ally-wheel 50 on said shaft 20. This rotates a sprocketwheel 46 on the otherend of the shaft 38 in a direction opposite to that arrow in Fig.1 through the medium of a 7 travels upon the sprocket 46 and also upon a sprocket 47, Fig. 6, rigidly; attached to the slidable cone 48. The reel-controlling shaft 38 can also be alternately slowly rotated by hand in a Way to:un-,

windor pay out the rope or cable 2 from the reel B, and thereby slowly lower the drillingtool, by turning in the proper direction a londing rotary hand wheel shaft 41, Figs. 1, 2, and 4, supported in' bearings 43 on the frame A and carrying near its a worm 40, which meshes with a worm-wheel 39 on one end of the reel-controlling shaft 38. I

The hand-wheel shaft 41 is mounted in its bearings 43 for longitudinal or endwise moverearwardl y,

, ment in a rearward direction, in which way .it will be automatically moved or projected so as to disengage its worm 40 from theworm-wheel 39 by such worm-wheel 39 when the same is rotated in a direction .to wind the rope or cable upon the reel or drum B. It is held against a stop provided by the foremost bearing 43 in position to maintain its worm 40 in engagementwith the wheel 39 by the tendency on the part ofthe latter to rotate in the direction indicated by the arrow in Fig.- 1, which tendency is caused by the ten'sion of, the weight of the drilling-tool 1, upon the rope or cable 2.

vbut I prefer to use indicated by the When the reel-controlling shaft 38 is engaged by the hand-operated paying-out mechanism, the reel is locked against rotation by the engagement of the worm 40 on the hand-whe'elshaft41 and the worm-whee139 on the reel-controlling shaft 38; but when the reel is disengaged both from the hand-operated paying-out mechanism and the powerdrivendrill-elevatingmechanism it can atwill either be lockedagainst such rotation as will allow the descent of the drill by allowing the forwardend of a, pawl 55, having its rear end pivotally connected at the'angle 56 of a bellcrank L, which latter is pivotally-connected to a beam a of the frame A, to engage the teeth of a ratchet-wheel 54 on the reel-con mit of its free rotation by rearwardly drawing a longitudinally-extending and longitudinally-adj ustable hand-lever59, which slides in cleats attached to the frame-bars a? and a and has its forward end pivotally connected to the upper end of the upwardly-extending arm 58 .of the bell-crank L, so as toswing such arm 58 thereof rearwardly and downwardly, and thereby causea stud or bolt at the end of the forwardly-extending bell-crank arm 57 toelevate the pawl 55, so as to disengage the same from the teeth of the ratchetwheel 54. It will be observed that the operation of the tooth-en gaging pawl 55 by a bellcrank inthis manner is exceedingly simple and effective and dispenses with the heretofore-employed complicated mechanism for such purpose.

When the reel B the power-driven winding or coiling mechanism and is not locked by the pawl-and-ratchct locking mechanism, it can be checked, so as to hand brake-lever 63, having its-rear end su pported by a cleat attached to the frame-upright a and its forward end pivotally con posed link 62, so as to swing the latter rearwardly-about its pivotal connection-with the ,side bar a and thereby cause a cross-head 61 on the upper end of such link 62 to tighten a strap or band 60, attached to the ends of the cross-head 61, about abrake-wheel 64 on the reel-controlling shaft 38.

If-a sand-pump is employed in the operation of sinking the well, it can be lowered into 'and withdrawn from the latter by meansof a sand-pump rope 51, Figs. 1 and 2, which depends from and is reeved about a sheave 44 on the mast C. From thesheave 44the sandpump rope 51 extends downwardly to and is coiled upon a rotary sand-pump reel L, which is carried by a rotary shaft 67, journaled in bearings supported at the rear of the machine by the rear frame-uprights a a but which is rotatable independently of its carryingshaft 67 and-is slidable along the same. The sand-pump can be loweredinto the well trollingshaft 38 or'be unlocked, so as to perdrawing rearwardly a longitudinally-disposed isdisconnected from both the hand-operated paying-out mechanism and,

check the descent of'the tool in the well, by

IIO.

ne'cted to the lower end of a vertically-disby allowing the reel K to be independently turnedby the weight of the pump. The reel can be rotated, so as'to wind the sand-rope thereon, and thereby elevatethe pump, by first operating a longitudinally-extending lever 70, pivotally connected to the machineframe at 71 and having its forward end in engagement with a clutch member (58,Fig. 6, slidable upon the driving-shaft 20, so as to throw suchclutch 68 into engagement with a cooperating clutch member formed on the hub of the belt-pulley 27 on said shaft 20, and thereby cause the latter to rotate the reelcarrying shaft 67 alone through the medium of a sprocket chain 67 traveling upon sprocket-wheels G6 and 65, rigidly secured, respectively, upon shaft 67 and to the loose driving-shaft clutch member 68, and by thus operating a short longitudinally disposed hand-lever 75, pivotally connected to the machine-frame and having its forward end in engagement with one end of the reel K, so as to slide the latter along its carrying-shaft 67 to an extent to cause the engagement of a "friction-cup 73, formed at its opposite end,

" with a cooperating friction-cone 72, secured to or formed integral with the fixed sprocket 66, and thereby cause its rotation by its carrying-shaft 67.

With'furthcrreference to the framework of the machine it will be understood that the body-frame A is of suitable construction for supporting the operating mechanism and is supported on front and rear-sets of wheels.

The master derrick 0 is desirably so constructed as to permit of its being raised and lowered at will, and it can of course be constructed and operated in any desired manner. However, as a preferred arrangement and matter of further improvement it can be raised by turning a handle 81 on one end of rotary reel 80, Fig. 8, supported below the machine-frame A, so as to wind thereon a rope 77, which extends rearwardly therefrom to and about a sheave '79 at the rear of the frame A thence upwardly and rearwardly toand about a pulley 78 at the end of a lower'swinging mast-section c, which is the rear end thereof when such section is in a lowered or horizontal position, and finally forwardly to the outer end of an extension (1 attached to the end of an upper swinging mast-section c, which is' the forward end of such section 0 when the same is in a lowered or horizontal position, in a way to draw downwardly and forwardly upon the sheave 78 at the end of the lower mast-section c and also downwardly and rearwardly upon the end of the extension 0 of the upper mast-section c. This causes the lower section 0' to swing about its hinge or pivotal connection with the upper end of the frame-upright a and assume a vertical position, with its lower portion alongside of the upright a ,-and also causes the upper mastsection 0 to swing about the hinge or pivotal connection which its lower end has with the upper end of the lower section '0' and assume,

a vertical position about the latter, wi thits extension 0 in position alongside the same.

Of course the mast can be lowered by turning the handle 81 of the reel so as to unwind orpay out the rope 77 from the reel, and thereby gradually release the lower ends of the lower section c'and of the extension 0 on the upper section 0 and allow such sections to assume a substantially horizontal position,

I with their connected ends resting upon the upper end of the forward frame-upright a. Itwill be seen that in this way the mast can be easily raised and lowered by a single operator in a single simple operation requiring but little expenditure of power. Of courseamast having more than two be raised and lowered in the same way, the essential feature being to apply the operatingrope to each section at a point which will come into position below the point of pivotal or hinge connection of such section when the sameis in elevated or vertical position.-

When in an elevated position, the mast can be there held and braced by a brace 82, which {can have its ends connected, respectively, to

the upper mast-section c and the upper end of to the upper end the frame A.
