APPARATUS FOR PUMPING AND F LOW|NG OIL-WELLS.

SPECIFICATION forining part of Letters Patent No. 276,116, dated April 17, 1883.

Application filed September 13, 1882. (No model.) i

To all whom it may concern: I

Be it known that I ELI SAMUEL WILLIAM- SON, of Bradford, in the county of McKean and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for the following is a full, clear, and exact description. r

This invention is an improvement in apparatus for working oil-wells for which Letters Patent No. 262,874 were granted m e August 15, 1882, and in which an independent wedging device, an elastic or flexible packer, and a slip-joint construction of tubes were used in the place of the longline of fixedand close-fitreadily anchoring the apparatus and for its easy removal from the well also for working which the working-tube was of reduced dimensions and movable, acting both as a pump-rod The invention consists in a novelconstruction and arrangement of the wedging devices for anchoring the apparatus in the well; also in a depressed and more efficient arrangement of the packing-box for the working-tube below the well; and in certain other constructions and combinations of parts, whereby the generaLefficiency of the apparatus is improved.

Reference is to be had to the accompanying drawings, forming a part of this specification, in'whicli similar letters of reference indicate corresponding parts in all the figllIESr Figure 1 represents a vertical section of an oil-well with my improved apparatus applied. Fig. 2 is an elevation of the upper portion of the apparatus with the walls of the well in section, and showing the wedging devices in a released position. Fig. 3 is a horizontal section upon the line a; w in Fig. 1.

A indicates the walls of the well, and 'B the working-barrel, of reduced diameter, anchored at or near the bottom'ot' the well, substantially as hereinafter described.

(J is the pumping-tube, arranged to extend f'rom or above the top of the well-hole to or near the bottom of the working-barrel.

Dis the taperin gelon gated box or cone used for anchoring the apparatus in the well, and through a hole in which the pumping-tube (J is free ,to work up and down. This cone, which constitutes a portion of the wedging devices, differs from thecone employed in my recently-patented apparatus hereinbefore referred to, inasmuch as it occupies an inverted position and has no packing-box within it, but allows of the pumping-tube passing freely through it; also is made to rest upon a series (preferably three) of reins, E, arranged on the outside of the cone or within longitudinal guiding-grooves bin its exterior. These reins, which are constructed with serrated or other suitable clamping-heads, c, at their upper or spread ends, that bear against the walls of the well, are hinged below, as at d, to a coupling,

F, and at or near the bottom of the cone D is a ring, G, which holds the reins in their places, and, further, serves as a catch or support for the heads 0 of the reins to rest upon, as shown in Fig. 2, when drawing the apparatus out of the well. Said reins, however, may be otherwise connected with or be made to form parts of the'cone. The coupling F is sufficiently open at its top to-allow of a bumper or bar, 0, on the pumping-tube G to pass through when said tube is drawn up to raise the cone D from within the reins E. The ring G, when drawn up with the cone 1), draws the reins E from the walls of the well and loosens or frees them at their tops.

Into the lower end of the coupling F is screwed a tube, H, which extends down to a coupling, I, that rests upon the rubber or elas-- bar '6.

In the lower end of said coupling I is secured a tube, K, which extends down through the packer J, and passes through a coupling, L, on

the under side of the packer, andwhich has a collar or projection, j, on its lower end, to pre vent its pulling through the coupling L.

' end of this reducing-coupling N is a smaller tube, 0, which extends down to a coupling, P. This coupling P connects the lower end of the tube 0 with a gland or follower, Q, of a packing-box, It, containing any suitable packing material, 9, and through which the pumpingtnbe 0 works.

In the lower end of the packing-box R is screwed the working-barrel B. This arrangement of the packing-box immediately above the working-barrel admits of the pumping de vices working closer to the bottom of the well.

The working-barrel B connects at its lowerend with a screw-coupling, S, within which is a valve, 71, arranged at the bottom-of the working-barrel and controlling an inlet-aperture, i, said valve operating in concert with a deliveryvalve, k, in the bottom of the pumping-tube G.

Arranged around the lower end of the pumping-tube is a collar or projection, I, that prevents the upper passage of said tube out of the working-barrel by striking or coming in contact with an interior flange, m, on the upper end of the barrel.

Projecting downward from the lower end of the coupling S is a perforated pipe, T, through which the fluid passes in its way to the working-barrel.

The whole. apparatus is first put together, and then let down to the bottom of the well 'until the perforated pipe T strikes said bottom. The pumping-tube C then drops or is worked down, its lower collar, Z, leaving the top of the working-barrel, until the bumper or bar 0 rests upon the coupling I. This throws additional weight upon the elastic packer J, causing it to expand, and the cone D, which had previously occupied a raised position, as in Fig. 2, follows down into the reins E and forces or throws the clamping-heads c of said reins out against the walls of the well, and when the weight is reduced by the lift of the pumping tube and its attached bumper, e, from 0d the coupling I, the cone D, having dropped into the reins E and expanding them,

as described, anchors or holds the apparatus to the bottom of the well. The length of stroke of the pumpingtube is or may be equal to the length ofthe tube H, but should not exceedit.

Thegeueral action issimilar to that of my previouslypatented apparatus hereinbefore referred to, the oil being discharged from the top of the hollow pumping-tube as said tube is worked up and down for the purpose.

When it is desired to remove the apparatus froin the well, the tube 0 .is drawn upward till the bumper e strikes the bottom of the cone D, and in the continued lift of the pumping-tube 0 causes the cone to be drawn up through the clamping-reins E until the ring G- strikes underneath the heads 0 of the reins. Continued lift then draws up all the parts above the packer J until the collar j strikes underneath the coupling L, when the lower part ofthe apparatus may also be drawn up or out of the well in common with the upper portion thereof.

By the use of the packer J the oil may be either supplied by direct flowthat is, when thereis a sufficient natural pressure-or by the working of the pumping-tube, as described.

The slip-joint construction of the apparatus, as described, provides in a most eflicient manner for raising or lowering the apparatus, and for removing it when required, as herein set forth.

Instead of making the reins Ewitli fixed clamping-heads at their upper or spread ends, said reins may have plain heads, and have serrated cams pivoted to or within said heads to bite against or on the walls of the well, and sliding pins or bumpers be arranged in the lower portions of the heads, to one side of the pivots of the cams and projecting through or below the heads, for the ring G to strike and release the cams from the walls of the well, and hold them released when drawing the apparatus out of the well.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an apparatus for pumping and flowing, the combination of the pumping-tube G, the surrounding part D, the bar 0, fixed on tube G, and the coupling I, extended inwardly nearly to the tube 0, whereby the movement of the pumping-tube is regulated, as described. 1

2. The combination of the bumper or bar 6 on the pumping-tube O, the upper open-ended tube, H, the lower hinged or pivoted clamping-reins E,and the cone D, essentially as described.

3. The combination, with the downwardlytapering cone D, of the reins E, arranged on the outside of said cone, provided with clamping heads 0 at their upper ends, passing through a ring, G, and hinged at d to a coupling, F, whereby the pumping-tube maybe locked to or unlocked from the walls of the well, as described.

4. The combination, with the cone D and hinged reins E, of a ring, G, made fast on cone D, and constructed as described, whereby said ring serves both to hold the reins in place and form a rest for the clamping-heads, as shown and described.

5. The combination of the pumping-tube C, the cone D, the lower hinged or pivoted clamping-reins E, the upper open-ended tube, H, the bumper e, the coupling I, the tube K, with its lower collar, f, the coupling L, through which said tube slides, the connected tubes M O, and working-barrel B, having a closed upper end around the pumping-tube, and the collar or projection l on said tube,

substantially as and for the purposes herein ling I, the. latter connecting the tubes H K, set forth. resting upon the packer, arranged loosely on 6.
