l To crZZ whom t may concern Be itknown that l, JOHN E. GABLE, a

resident of Evanston, in the county ofI Cook..

and State oflllllinois, have invented certain new and useful improvements in Well- Pil-mp5. of which the following is a full, clear, and exact description.

rfhe invention relates to' pumping-appa ratus for wells.

ln well-pumping apparatus heretofore devised in which a rotary pump was employed for lifting the liquid it has been necessary to provide a pipe for conducting the Huid y from the pump at or near the bottom of t-he well tothe surface and in addition thereto another longitudinally extendm element,

such as a shaft for operating or e ect-ing ro-" tation of one of the pump elements necessary to raise the water to the surface and through said pipe. Une of the main objects of the present invention is to provide an improved apparatus in which the pipe through which the water is lifted serves also as means for transmitting power or revolution to' one of the pumpelements necessary to cause the water to be lifted through the pipe. Resultantly, when a pipe serves the double purpose of a Huidconductor and a drive-shaft, the necessity of employing a shaft extending from the top to the bottom of the well is avoided. This feature of advantagel is particularly important in deep wells. Furthermore, all 'the attendant disadvanta es of employing a long shaft or line of sha ting, likely to become out of alinement will be entirely avoided.

Thel invention further esigns to provide improved mechanism which will be automatically secured in the well-pipe when lowered to then bottom' thereof to hold one of the pump-elements to eect proper coperation of the several elements of the pump.

The invention also designsto provide improved pumping-apparatus for Wells', which is simple in construction and eiiicient in operation.

lIn the drawings: Figure l is a' section of a Well and apparatus embodying theinvention. Fig. 2 is a section on an enlarged scale taken on line 2-2 of Fig. 1. Fig. 3 is a section on line 3-3' of Fig. 2. Fig. 4 is a section through the pump-anchor. Fig. 5 is' a section on line 5-5 of Fig. 4.

A. denotes a sunken well-pipe extending from the bottom lof the well to the usual platform b on the surface of the ground. A pipe c extends vertically through the well-pipe and is journaled near its upperv end 1n a suitable bearing d on a suitable support e. A head j" is connected to the open upper end of the Well-pipe and support d 1s mounted, for convenience, von sald head. A chamber f is formedin the head f and one or more pipes f2 are connected to said chamber to carry of the gases from the well-pipe when the improved apparatus is employed for pumping oil-wells or those containing gases. Pipe c extends through a suitable packing-.box f3 in the head f to prevent leakagel of gases around the pipe. A pulley g is secured to the upper end of pipe c, serving as a means for driving or rotating said pipe.

The `liquid is raised fama@ wen by' a rotary-pump if: which forces it through the pipe c. A pipe-terminal Zz having out-let openings h therein is secured to the upper end of the outlet pipe o and on the upper end of said4 head, is a suitable bearing f1.2 for a casing z', into which the. liquid is discharged through the openings h in the pipehead ZL and a lpipe j may be. employed for conducting the fluid to any point desired.

Rotary pump lc serves as the means for lifting the liquid from the"bottom of thev well, through the pipe c and into the casing z'. Thisxrotary pump comprises essentially other to force fluid through the pipe c. In

the embodiment offthe invention illustrated, the pump Casing Ic is secured to rotate with the pipe c and a part of the piston is held against rotation with the casing to effect the relative movement of the pump elements to force the4 Huid upwardly through the pipe c.

An anchoring-device Z adapted to be automatically secured to the welli e A when the pump is lowered, is providd) for securing one of the pump-elements against rotation with the pump-casing to render the pump operative to lift the liquid. This anchoring-device Z comprises a pair of Wed eblocks Z', Z2, slidably connected together y pins Z3, and slots Z4 formed in the wedgeblocks respectively so that when the anchoring-device is lowered in the Well-pipe and the wedge-block Z2 encounters an obstruction, such as the bottom of the well, it will be arrested and the other wedge-block Z may be forced downwardly to cause the anchoringdevice to' become` locked to the well-pipe,

thus securing it against rotationl therein.

The connection between the upper wedgeblockZ and the pump-piston consists of a rod m having itslower end slotted'and4 an elongated eye Z8 or staple n on the wedgeblock ZV `which extends through the slot in the lower end of the rod vm. This constitutes a lost-motion connection to permit relative vertical movement of. the pump-rod lwith respect to vthe anchoring-device but raise the wedge-block Z until the-anchoring device has been unlocked or released from the well-pipe. Therefore this anchoringdevice' is automatically rendered operative and inoperative when the pump is lowered or raised respectively. l'

The pump employed is preferably one which forces the liquid upwardly and positively; The lower end of the pump-casing is connected to a pipe 7c3 having perforations y 709 therein, through which the liquidwill pass to the inlet-chamber 21 ofthe casing at,

one side'of the piston. The piston .comprises a pair of toothed members 71:5 and k6, geared together by pinions le" and ks. The

piston-members have longitudinally interlitting ribs or faces and grooves so that when they are rotated relatively, fluid. will not pass between the Vpiston-members. The pump-casing is provided with-a segmental inner periphery 20 at each side of one of the well-pipe, a pipe in the well-pipe, means for piston-members so that during relative rotation of the casing with respect to the piston-members the fluid in the spaces between the outer ribs of the piston-members will be confined between the piston-members and the walls 20 andforced from the inlet-chamber 21'to the outlet-chamber 22 atl the opposite sides o f the piston-members. Each plstonmember is provided with a stud or shaft 23, journaled in `

horizontal walls

24 and 25 at the top and bottom of said members respectively.v An internally toothed gear 30 is .secured tothe upper end of anchor-rod m which meshes with a pinion 31 on one of the piston-studs. In operation, when the-pumpcasing is rotated, one of the piston-members being held against rotation with the pump` casing by the anchor-rod m and gears 30 and 31, relative rotation of the piston-members with respect to the piston-casing will result to cause these members to force the liquid from the inlet-chamber to theA outletchamber of the casing. Resultantly, the

forced into the ground, the pipe c with thev pump and anchoring-device connected-to its lower end, is lowered into the well-pipe. When the lower wedge-block Z2 encounters the bottom of the well it will be arrested chor-rod m will then force the upper wedgeblock Z downwardly until the anchoringdevice has been locked to the well-pipe. The apparatus at the upper end of the well-pipe being then in place, pulley g will be driven to rotate the pipe c which will operate the rotary-pump to raise and force the liquid through the pipe c into the casing z'.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1'. In a well-pump, the combination of a well-pipe, a plpe extendingl downwardly into the well-pipe, means for rotating said inner pipe, a rotary pump in the well-pipe and comprising a piston and aycasing, said casing being connected to the lower end of said pipe and driven thereby,`the piston comprising a plurality of members pivoted in the casing, and a vertically adjustable anchoring device in the well-pipe and connected to one of the piston members 'for holding it to cause relative rotation of the pump and piston.
