Fig. 24 lis a detail,

the apparatus for sinkingwells by means of rotary and reciprocating drills, which may be used separately or together in connection with a Water-supply, and to improve the tnbing, and means for closing it when the well is complete. I accomplish these objects by .improving the construction and operation of i the dierent parts and the entire apparatusv as a whole, as illustrated in the drawings, and hereinafter specied.

That which I claim as new willfbe pointed out in the claims.

In the drawings, A represents a well-tubing formed, as usual, of sections coupled togetherf by couplings a, and, as shown in Fig. 2, provided with a coupling a, having a side nozzle near its upper end for the discharge of water. This tubing A is to be of any desired diameter.

B is the lower end section or filter lof the 7o tubing, which has perforations b, for the entrance of water, and ribs d on its circumference.

C is a rotary drill or cutter head, which is provided with cutting-teeth c on its lower edge, as usual, and at its upper end is screwed onto the filter B. This drill has a taper or shoulder cf on `its interior lower edge, as shown in Figs. l and 3.

D is a wire-cloth or perforated screen se- 8o cured to the section B between the ribs d. The ribs dare a protection for the wire-'cloth from injury when the tubing is rotated while the well is being sunk. This wire-cloth D and the perforatedeud or section B form a `l lter for the tube when completed.

E are the blades of an expansion-drill, eac?` having cutting-edges e., as shown iii-Figs. 1=, 5, 6, '7, 8, and 24.'

. F (see Figs. 9 and 10) is a socket havinga 9o slot F part-way of its length to receive thef. drill-blades E, which are pivoted in the lower end ofthe slot F by a pivot f". As shown in Fig. 9, the socket F has a shoulder or taper` 'l f on its exterior lower edge corresponding with the taper or shoulder c of the drill-head C, which furnishes a means ot' support for the expanding drill from the tubing A. G is the expanding piston which fits within the socket F and at its lower end isprovided roo with wings g, which fit in the slot F, as shown in Figs. 6 and 7. This expanding piston has openings g for t-he passage ot water, as shown in Fig. 11, and a central stem G, as shown in Fig. 5, G, and 7.

lll is a cap or collar loosely mounted on the stem G of the expanding piston G and adapted to tit in a recess h in the socket F, and held up in the recess by a spring 7L, which rests on the top of the piston-head G.

l is a head or casing in which the socket 1J1 is located. 'l`his.casing is screwed onto the socket F, and the socket F is coupled to the drill-rod by a coupling i, which is screwthreaded so as to screw on in the reverse direction from the rotation intended for the drill.

l is the drill-tube for the expansion-drill.

K is a packing formed of two plates j j, and a suitable packing j between the plates j. This packing is secured on the drill-tube J by a suitable coupling k, as shown in Fig. l.

lL is a conical plug, which fills the lower end of the drill-head C, fitting the taper or shoulder c. After the well has been sunk the plug is dropped into the tubing to close the bottom of the tubing, so that the water must enter through the perforated end or iilt-er E.

M (see Figs. l2 and 25) is a watersupply head having supply-hose N attached thereto by couplings m, and secured tothe drill-tube d by a stufiingbox n.

0 is a swivel secured to the supply-head M.

P is a pulley-block connected with the swivel 0 by a link o.

Q is a hoisting-rope. This rope Q may run through an upper pulley-block it and the lower block P, as shown in Fig. Q5, or it may be attached directly to the swivel@ by a link o, as shown in Fig. l2.

S are clamping-bars to clasp the drill-rod J, each oar having a bend p to fit against. the rod, and the bars S are clamped tothe rod by bolts q passing through them.

'li are clamping-bars for attachment to the tubing A and to the clamping-bars S. llach bar at its center is formed with a bend r to tit the tube A, and at its outer end with an arm s, having at the upper end a hook t to tit over the ends of the clamping-bars S. The clamping-bars 'l are secured together and clamped onto the tubing A by suitable bolts u. These clampingbars S and T form a connection between the tubing A and the drill-tube .Lby which the drill-tubeJ can be rotated from the rotation ofthe tubingA or the tubing can be rotated from the rotation of the drill-tube J, and in ease it is desired not to havethe common rotation by looseningeitherthe @lampi iig-bolts q or u the connection between the tubing A and the rod J is broken, and either one can be rotated without rotating the other.

diie tubing A and the rotary cutter C are sunk by rotation in the ordinary manner untii the 'friction on the side ot' the hole prevents further rotation and descentby force of gravity, or the cutter C ceases to act. When this point is reached, an expansion-drill and its tube J is inserted in the tubing Ato work with the tubing or independent thereof, as maybe necessary. When the expansion-drill is used, it is of a diameter to tit the cutterhead C. Such expansion-drill can be worked either by raising and dropping or by rotation, as desired. The expansion-drill and rotary cutter herein are designed to work together or separately. \Vl1en the expanding drill is used to sink the hole below the tubing, the head must be smaller than the end of the cutter C in order to pass through it.

rlhe parts of the expansion-drill are assembled by placing the spring h on the stem G of the expanding piston G and the cap Il on the stein G above the spring, and then inserting the expanding piston G in the blade-carrier F, with the wings g in the slot F" and the cap ll inthe recess h. The blades are then inserted in the calrier l" and secured by the pivot-pin f.

The casing I is screwed onto the carrier "F from the upper end until it comes iu Contact with the shoulder f, as shown in Figs. 5, 6, and 7, or it is screwed onto the carrier F from the lower end, as shown in Fig. 24, in which case the shoulder or bevel f is on the casing The easing thus forms a covering for the blades and carrier and also prevents the withdrawal of the pivot-piaf".

'.lhe expanding drill is used by inserting the head i, with the parts connected thereto, and the drill-tube J, into the tubing A until the shoulder f at the lower end ot the carrier E, or a suitable taper at the lower end or" the head i, as shown in Fig. i, rests upon the shoulder or iiange c" ot' the drill-head C, and when in place the tubing A and the drill-tube J can be rotated together by connect-ing them one with the other through the clamping-bars S and 'l`,or they can be rotated independently, or the drill-tube J can be reciprocatcd, or both tubing and tube can be reciprocated.

The drill-blades are expanded by the expanding piston G, which presses upon the corners of the blades, as shown in Figs. (i and 7. The expanding piston G is pressed down by the force of the water inthe tubeJ, which forces down the cap il and the pist-on G through the spring h", which forces the blades open. The water passes down around the cap 1I and through the holes g in the expanding piston @,oraround the edges o said piston to the point of cutting. 'ihe water thus used washes away the cuttings of the drill, keepingthe drilthole clear.

water-pressure in the tube J. When the water-supply is cut offfthe spring h will litt the cap il into the recess fz, and the nistonG will rise, relieving the pressure on the blades and allowing the drill-blades E to be eiosed. By this means the expansion of the blades l is controlled by the water-supply.

"When the rotarycuttert has become worn w rllie blades y, it will remain expanded as long as there is a iOC , expands the blades E below the drill-teeth c,

when the tubingA and tubeJ can be rotated or reciprocated together, as necessary for the L work to be done, or the tube and expansion- .is in place, thus obviating the necessity of are applied, as shown in Fig. 12.

drill can be operated alone. The shoulder or bevel c" is also designed to form a contactface for the plug L, which is driven into the tubing to close the lower end when the well Yis complete, thus permitting the water to enter .through thelter B only. The wire D of the lilter is protected during the descent of the tubing A by theribs d on the ilterB.

In using the expanding drill no removal of the tubing of the well is necessary, and when the well is cm plete the tubing, with its vfilter,

pulling up the tubing, which would allow the walls of the well to cave in.

In order to rotate the drill-tube J and tubing A together, the clamping-bars S and T are used. When it is desired to rotate the drilltube J from the tubing A, the bars S and T Then it is desired torot-ate the tube J, the clamp is applied, as shown in Fig. 23. W'heuever it is desired to rotate either the tubingA or tube J alone, the clamping-bars S and'l are loosened or removed. `By means of the hookst on the bars T, which hook over the bar S, and the shoulder f ofthe carrier F of the expansiondrill, which rests on the shoulder c" of the rotary cutter' C, thetubing A and the tube J are locked together, so that they can be reciprocated together by the rope Q.

The water-supply head M is attached to the tube J, which supplies the water for washing away the cuttings at the point of cutting and also opens the expansion-drill. .The packing K prevents the water from passing up through the tubing and forces it to pass up outside of the tubing. XVhen it is desired to give a sudden force or impetus to the water, the tube J is raised in the tubing A and dropped, which causes the packing K to force the water below it out below the cutter C, thereby Vremoving any clogging at that point.

In order to rotate both `tube J and tubing -A together or separately, and to reciprocate them together or separately, and to raise either alone or both together, I provide the following' combined. 'clamping dev-icc and winding-drum:

A' represents theside pieces of the frame. B' are cross-pieces forsupporting the bottom plate of the clamp. n

C' are cross-pieces for supporting the drm-1 G is a plate having on its underside leaves or cogs b', to mesh with the leaves a.' of the 4wheel F'.

H' is the bottom plate, bolted or otherwise secured to cross-piece B', and having an annular Iiange d', which lies outside of the flange c' of the plate G' ,which iianges c" and d' furnisha bearing and support for the plate G.

I' are uprights, secured to the plate G' by bolts e on opposite sides of the central opening ot the plate and in line, as shown in Fig. 13. i

J are clamping-bars, each bar at its outer end having a hookf to pass around the uprights I', and each bar having at its center an angular bend g' to bite against the tubing A. The bars J are attached to each other by bolts h' and hand-nuts i', by means of which the two bars J can be drawn together to cause the angular bends g to firmly bite the tubing. By using two bars J', each having an angular bend g', the center of the tube clamped willalways bein the line between the hooks f', so that tubes of different diameters can be clamped and not interfere with v the engagement of the hooks f with the two uprights I.

.As shown, two sets of clamping-bars J are used.` One set is attached near the lower ends of the uprights I and the other near their tops. As the tubing descends and the bars reach their limit of descent, they are loosened and raised alternately. By this means the tube will be continually rotated.

K are journal-boxes on the side pieces A.

o' is a lever for operating the brake-band m. The levero is hinged to a bracket q on the frame S", and connected to the band m' by a link p.

U is a gear-wheel loosely mounted on the IOO IIO

driving-shaft R. This wheel U has a hub U, in which is a cam-groove u and a faeceam u'.

"V is ahead or block, which is keyed onto the shaft R by set-screws i and is provided with a sliding latch V'. The latch Vis pro.- vided with a pin 1f in its outer end, which runs in the cam-groeven. This pinar is preterable to the forgings on the latch heretofore used, because when worn it can be readily and cheaply renewed. The inner end of the latch V runs in a groove 7" in the end of the drum '1" and engages with a cateh'or block s', secured in the drum T. rlhe block or head Vis provided with cushions v', made ot' rubber or other yielding material, as shown in Figs. 19 and 21, to relieve the shock of the engagement of the latch V with the catch s.

X is a worm-gear to engage with the wheel U, mounted in a frame X', which is hinged to the frarue S. The Worm-gear X has a hand-wheel a", by which it can be rotated. As shown in Fig. l5, the worm-gear X can be turned up out of engagement with the wheel U.

The lever W has a beveled shoulder x to engage with the hand-wheel .fr for lifting the worm-gear X out of engagement with the wheel U when the latch V is thrown out of engagement with the winding-drum.

Y is a ratchet-wheel loosely mounted on the shaft R. flhis wheel has a clutch y on its interior face to engage with a clutch y' on the end of the winding-drum T. This Wheel Y is moved longitudinally on the shaft R by a lever-Y', which is pivoted to a bracket Y" on the frame S, and has a collar y", which enn circles the hub of the wheel Y.

Z is a worm-gear to engage with the wheel Y, said gear being mounted in a frame Z', which is hinged to the frame S. The wormgear Z has a hand-wheel E, by which it can be rotated.

Z is a hooked link for connecting the levers y' and worin-gear Z.

.2" is a shoulder on the lever Y for lifting the hand-wheel z.

`When the lever Y is moved to throw lthe clutch on the wheel Y out of engagement with the Winding-drum, the worm-gear Z is at the same time thrown out ot' engagement with the Wheel Y.

The operation of the rotating and reciprocating device is as follows: The power-shaft R', which is driven by steam or horse power, drives the shaft E through the sprooketwheel Q', chain P', Wheel 0', shaft L', and bevel-Wheels M. rlhe shaft E rotates the plate G' through the beveled gear F'. The `tubing A, as shoven in Figs. 13 and 14, or tube J, as shown in Fig. 23, is inserted through the opening in the center of the plate G', and is` clamped by the clamping-bars J' on the uprights l. rihe bars J are drawn together by Quaero the bolts h' and handlnuts z" or other suitable meansto cause the angularbendsg' to biteonto the tube or tubing. The rotation of the plate G', carrying the uprights ll', rotates the tube or tubing through the clamping-bars Jl. The descent of the drill carries the clamping-bars J downward on the uprights ll', because they are simply hooked onto the uprights l'. As the clamping-bars reach their limit of descent, they are loosened and raised alternately without stopping the machinery. tVhenever it is desired to stop the rotation of the tube or tubing, the clamping bars J are loosened by unscrewing the hand-nuts i', or if it is desired to stop the entire rotating device the clutch M is thrown out of gear by the lever N. By the use of the bars S and T, already described, the tube and tubing are rotated togetheru This rotary clamping device is very simple and effective and can be used in connection with the winding-drum for reciprocating device, because it is so easily thrown out of or int-o use, and also because it permits a longitudinal movement in the tube or tubing.

'lhe operation of the Windingdrum is as follows: Thev rotation of the power-shaft R rotates the head or block V, and the latch V engages with the catch s' on the Winding drum, winding the rope Q onto the drum and lifting the drill-tube. cam-groove u until the cam u draws the latch V away from the catch s', releasing the vrinding-drum, which is rotated iu the reverse direction bythe weight of the drill-tube on the rope Q. When the pin t' passes the releasing point in the cam-groove u, it is immediately returned by the cam-groove u, forcing the latch Y' again into the groove r to engage again with the catch s'. As the eamgroove u returns the latch quickly, ll provide the face-cam u to engage with the end of the latch V' and assist the cani-groove u in returning the latch. 'lhe face-cam u' being farther from the center of rotation than the ca1n-groove u, it moves more rapidly and will accordingly move the latch Y' linto engagement with the winding-drum catch with a quick positive movement. By continuously rotating the head or block Y it is evident that the drum will be alternately Wound forward and allowed to be unwound, alternately lifting and dropping the drill tubing or tube. By rotating the Wheel U forward or backward by the worm-gear X the position of the cam u is changed, so as to release the latch later or sooner, as may be necessary, thereby regulating the drop of the drill as needed. The rope Q can be continuously Wound onto the drum for raising the drill-tube by raising the Worm-gear X out of engagement with the gear-WheelU, allowing the Wheel U to rotate with the head V, as shown in Fig. l5. When it is desired to throw the latch V' out ot engagement with the catch s' of the Winding-drum, so that the drum can be held stationary or unvvound, the lever W 1s moved to the right, moving the wheel U l'lhe pin v runs in the l IIC' 'cam, which gives the latch a 1in my present device.

and head V to the left, withdrawing the latch Y from engagement with the catch s', and lifting the worm-gear X by the engagement of the shoulder with the hand-wheel a', thereby permitting the head or block V and Wheel U to rotate with the t shaft without engaging with the drum T. The latch V is rectangular inl cross-section and the pin c projects on each side of the latch V', so that when the pin v or the end of the latch V' be-- comes worn the latch can be Itaken 'out and turned over, presentinga new face for engagement with the catch s', and a new pin c to run in the cam u. The drum is held against backward rotation by the pawl j and ratchet lwhen it is desired to hold the drum stationary. When it is desired to allow the-weight on the rope Q to descend, the pawlj is lifted and the rotation of the drum is controlled by the brake fm', as usual. Then it is desired to hold the drum stationary or turn it slowly forward or backward in raising weights, the clutch y on the wheel Y is thrown into engagement With the clutch y on the drum T and the worin-gear Z is held firmly in contact with the wheel-Y, preventing the rotation of the drum T and wheel Y. When desired, the worm-gear Z can be rotated by the hand-wheel Z, turning the drum forward or backward, as desired, thus operatin g the drum independently of the power shaft R. The link fr of the lever W and the link y" of the lever Y are designed to hold the worin-gears to which they are respectively applied in engagement with their gear-wheels. These links are preferably made detachable from the worm-gears, so that the worin-gears can be lifted independently of the levers WV or Y; but it is evident that they may be made so as to lift the worm-gears without the use of the shoulders on the levers lV and Y.

As shown in Fig. 22, the wheel Y has ratchet teeth or cogs to hold more firmly against the worin-gear and to permit the drum T to rotate forward with the shaft R' when the worm is in engagement, permitting the rope to be `wound on the drum, while preventing unwinding and avoiding injury to the cogs when the drum T is rotated from the opposite end.

In my former patents, No. 258,889, dated June G, 1882; No. 871,548, dated October 18, 1887, and No. 382,689, dated Mayl, 1888, are shown devices for a similar purpose; but the latches there shown are thrown into engagement with the drum by springs instead of by a positive .motion It isy evident that the form of the cam on the wheel U may be varied, as is necessary for the form of latch used, the present form of cam and latch being best now known to me.

By means of the clam ping-bars S and 'l and the shoulders f and c the tubing A and tube J are locked together, so as to be rotated together, and by meansof the hydraulic expansion-drill the drill-blades are expanded by the water while the weight of the rod `J is supported on the tubingA. By means ot the rotary clamp and the winding-drum the tubing A and ltube J can be rotated or reciprocated simultaneously or separately and the motion of the tube or tubing can be changed from rotation to reciprocation, or vice versa,without stopping the machinery. The tube can also be lifted without stopping the power or held stationary or lowered slowly or quickly, as may be necessary.

The dierent parts are all operated and controlled in such manner vthat one operator can easily control the working of the drill."

The feed of the drum is controlled by the worm-gear X, so that as the drill descends the rope can be gradually let out by the operator by turning the hand-wheel .r.
