WELL-CASING MACHINE.

Specification of Letters Patent.

Patented Oct. 1,1912.

To all whom it may concern:

Be it known that I, EDWARD J. PENNY- PAOKER, a citizen of the United States, residing at Los Angeles, in the county of Les Angeles and State of California, have 111- vented a new and useful Well-Casing Machine, of which the following is a specification.

This invention relates to a machine for manufacturing sections of well-casing by telescoping and riveting together joints of sheet-metal pipe. In manufacturing wellcasing of this description separate single joints of pipe are first made from metal sheets the edges of which are riveted or welded together with a longitudinal seam; then the ends of such joints are squared, and then the end of one joint which is slightly tapered for the purpose, is forced into another joint to which it is tightly fitted, and other joints are successively telescoped therewith until the required pipesection which may be of any desired length,

TI is formed. It is desirable that the pipejoints thus united shall fit each other very tightly so as to make a rigid casing that will stand the pressure of driving the same into the well to be eased, which well may in i some instances be of great depth, as 2000 feet, more or less.

An object of the invention is to provide superior means for forcibly telescoping the joints together and holding them while they "1 are being riveted whereby the work will be .done with maximum rapidity, and joints that fit each other most tightly may be easily and evenly put together, thus making a strong, straight, rigid pipe. In the proc- T ess of entering the joints, one end into another it is necessary for the workman to have direct access to the pipe section on top, bottomand both sides in order to effect the work in the most rapid and satisfactory "I manner.

An objectof this invention is to construct a machine adapted to telescope the joints and in a manner to hold them, that will give free access of the operator of the joints 1' for the purpose of entering one end of one joint into the end of another and for the purpose of riveting the joints together.

The accompanying drawings illustrate the invention.

.Figure'l' is a fragmental side elevation of solid lines in position ready for ramming a pipe-section to add another pipe-joint thereto, said pipe-joint being shown on the stake and against the abutment at the left of the pipe-section. Dotted lines at the left of the view indicate a position of the movable stake and its carriage before said joint was placed on the stake. Dotted lines at the right side of the View indicate the position of the ram-piston after the ramming has been effected. Fig. 2 is an elevation looking toward the left from line w Fig. 1. Fig. 3 is an elevation looking to the left from the arrow 3 in Fig. 1. Parts are broken to show the screw that raises and lowers the ram. The parts shown in Fig. 1

2 are omitted from this view. Fig. 4 is a plan of the ram and its frame looking in the direction of the arrow 4 in Fig. 1. A portion of the cylinder is broken away to show the piston. carriage in position on the track, parts being broken to contract the view and expose parts that would otherwise be hidden. Fig. 0 is an enlarged detail on line 00, Figs. 2 and Fig. 5 is a plan of the stake- 1 5, showing the device for locking the carriage against the thrust of the ram.

1 is a head mounted on a piston-rod 2 that is connected with a piston 3 which is operated by fluid pressure in a cylinder 4 to move the head horizontally. The parts 1, 2, 3, 4

constitute the ram. The same is adjustably mounted by means of a runner 5 whichis fixed to the rear of the cylinder and is movable in a vertical way 6 that is supported by a frame 7 on which is mounted a nut 8 in which is a screw 9 controlled by a handwheel 10 and operating a block 11 that is fastened by bolts 12 to the cylinder 1 for raising and lowering the cylinder relative to the frame to bring the head centrally into line for ramming pipes of different diameters.

The head 1 may be of cast iron having ribs 13 at the back to give it rigidity and may be faced with a plate 14 of sheet-steel, boileriron, or other rigid material to engage a pipe-joint that is to form a portion of the well-casing section which is formed of alternate inner and outer joints, as at 15 and 16, teleseoped together.

one or more racks 18 the teeth of which face in one direction along the track.

19 is a riveting stake fixed to a frame 20 and projecting therefrom toward the ram- I ming head 1. Said frame 20 is provided with an abutment 21 that faces toward the ram to hold the pipe-joint 15 or 16, as the case may be, as it receives the thrust of a pipe-joint 16 or 15, as the case may be, which is to be telescoped therewith.

The frames 7 and 20 are relatively movable, and except for convenience of operation or construction it is immaterial whether it is the holding frame 20 or the ram-frame 7 that moves. is made stationary at one end of the track 17, and the holding frame 20 is movable Preferably, the ram-frame 7 along the track, being provided with wheels 22 to run on top of rails 23 of the track.

In the form shown in the drawings, the ramframe 7 is fixed to the track 17 and the holdthat run on internal flanges 25 of said track.

The track may be formed of two I-beams. 26 1 held together by bolts 27 spaced apart by:

spacers 28.

The axle 29 of the thrust-resisting wheels f 24 is carried by hangers 30 which consist of 1 plates through which the axles 31 of the supporting wheels 22 extend; said hangers 30 being perforated to receive the axles 29 and 31, the latter of which is connected with the frame 20 by boxes 32 which are secured by bolts 33 to the channel-iron hangers 34 to which the hangers 30 are rigidly fixed by rivets.

The stake-carriage composed of the frame 20, and the axles, wheels, and hangers just seated; the purpose being to resist the thrust of the stake-carriage when the ramming is being effected. engage the teeth 40 of the racks except when The pawl 35 is adapted to held out of engagement therewith by means under the control of the operator.

' means shown for this purpose consist of the hand,-l.ever 41 pivoted at 42 to the stakeframe and connected by connecting-rod 43 with one arm 44 of a crank-lever, the shaft 45 of which is journaled in boxes 46 on the The stake-frame underneath the stake, the other l arm 47 of said crank-lever being connected by connecting-rod 48 with a bar 49 of the pawl that is fastened by bolts 50 to the sleeves 36 of the pawl so that when the lever 41 is depressed the pawl 35 may be lifted above the teeth 40 of the racks.

The holding carriage may be moved along the track by any suitable means. For this purpose a sprocket-wheel 51 is fixed to the rear axle 31 of the holding carriage and is connected by a sprocket-chain 52 with a sprocket-wheel 53 that is fixed on sprocketshaft '54 that is journaled in the frame 20 and is provided with a crank 55 by which it may be turned to rotate the carriage-wheels 22 in one or the other direct-ion for increasing or decreasing the space between the abutment and the ram.

The stake 19 is rigidly mounted in sockets 56-, 57, carried by the frame 20 and is held in place by set-screws 58. Said stake projects from the frame 20 toward the ramhead 1 a distance something greater than the length of one of the pipe-j oints which go to make up the pipe-section. Said stake is provided with a vertical perforation 59 for burs to go through when the stake is used for punching holes in the pipe-joints to be connected.

60 is a goose-neck provided at its free end with the usual perforation 61 to guide the punch for punching holes in the pipe-joints.

62 is a steel anvil seated in a seat 63 to i the stake for driving the rivets that are to unite the pipe-joints.

The stake and goose-neck just described are common in the art.

The impelling fluid, whether water, oil, steam, or air, may be controlled by a valve 64 operated by a shifting rod 65 which extends along the track within reach of the workmen, and may be suspended by cords 66 hung from the ceiling or from an elevated beam 67; said rod being connected by a link 68 with the valve-arm 69 so that as the rod is swung in one or the other direction it will move said valve-arm and turn the valve to direct the fluid from the inlet or supplypipe 70 to one or the other side of the piston 3 through one or the other of the feed-pipes 71, 72; the exhaust passing out through the other feed-pipe 72 or 71 as the case maybe, and through the valve 64 which is a fourway valve, to the outlet 73.

Trolleys 74 running on a track 75 and supporting sheaves 76 that carry loops 77 are provided to support the pipe-joints in position to be rammed. The connection '78 between said sheaves and trolleys are adjustable by means of turnbuckles 79 so that the height to which the pipe-section will be held may be regulated.

in practical operation two pipe-joints, as 15 and 16, will be started to telescope together and will then be placed upon the stake 19, and the stake-carriage will "be brought sufficiently close to the head 1 when the same is retracted as in the position-shown in solid lines in Fig. 1, to allow the head when operated by its piston to drive the joints against the abutment 21, and thereupon to ram the one joint half-way into the other; said joints being of equal length. In the operation of ramming, the pawl 35 will be allowed to rest in the notches of the rack so that when the ramming occurs the holding-carriage will be held rigidly on the track by the pawl and the thrust-wheels. After the ram-head is retracted the loops 77 will be brought around the section just formed, and the two pipe-joints will be swung in the loops free from the stake, and the lever 41 will then be pushed down to lift the pawl 35; whereupon the operator may turn the crank 55, thus to retract the stake-carriage until another pipe-joint may be slipped onto or into the end of the pipesection that is next the abutment. Then the carriage will be run forward as before until the stake has fully entered the pipesection and the abutment is in position to hold the added joint for the ramming action, whereupon the operation of ramming will be repeated.

It is usually desired to rivet the pipejoints together after they have been rammed. To do this each joint will be punched and riveted in the usual way while it is on the stake after having been rammed.

The stake is set on the carriage at such height as to accommodate the largest diameters of pipe intended to be rammed, and in order to bring the ramming head 1 to the appropriate height, the adjusting handwheel 10 may be turned in either direction as required to bring the center of the head into line 'with the axis of the pipe to be rammed. In order to allow this to be done readily the pipes 71 and 72 have flexible connections 81 and 82.

The lower ends of the hangers 30 may be held apart by a spacer 83 on the axle 29, and cotter-pins 84 may be passed through such axle outside the wheels 24 to hold the parts in place.

Particular attention is directed to the construction whereby no obstructions are in the way of the workman relative to the joints, the pipe-section or to the stake, so that he is given perfect freedom in handling the joints and section and the same are held by the stake ready for the riveting operation immediately after the ramming process has been performed, and all separation of the joints may be prevented by driving a number of rivets while the joints are held by the ram.

I claim 1. A track provided with rails having flanges, a carriage provided with wheels running on said track and provided with wheels running under the flanges of said track, said carriage also being provided with an abutment, a rack extending along the track, a pawl on said carriage to engage said rack, and a ram to telescope joints of pipe whenheld by said abutment.

2. In a well casing machine, a track formed of two I-beams spaced apart, two frames, one of which is movable along the track toward and from the other, wheels for the movable frame to run on flanges of the I-beams wheels for the movable frame to run under flanges of the I-beams, a rack in fixed relation to the track, a pawl on the movable frame to engage the rack, a ram on one of said frames, an abutment on the other frame, and means to operate the ram.

3. A pipe machine comprising a base; a frame mounted on the base and provided with an abutment and with a pipe section supporting stake on the same side of the frame; a second frame mounted on the base; said frames extending up from the base and being in movable relation to each other; a cylinder mounted on the second frame; a piston in the cylinder; the cylinder on the second f ame being opposed to the free end of the s ake; a piston in the cylinder and a ram on the plston movable between the frames toward and from the stake and abutment; the space above the base and between the frames being open and unobstructed; means to supply fluid to the cylinder to operate the piston, and means to temporarily hold the frames in stationary relation to each other.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 3d clay of March, 1909.
