DEEP-WELL PUMP ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 747,223, dated December 15, 1903.
Application iiled May 26, 1903. Serial No. 158,792.v (No model.)
-tion of the same.
My invention relates to pumps which are especially designed for operation in deep Artesian or cased wells.
It consists in a means for removably securing the pump mechanism within the welltube at any depth for operation and in a means forautomatically disengaging thelocking mechanism so that the pump-cylinder and all attached mechanism may be withdrawn or replaced at will and means for preventing and reducing the wear of the parts and for replacing said worn parts without disturbing the main portion of the pump.
In the accompanying drawings, Figure 1 is a vertical section showing inside latches.
Fig. 2 is a similar section showing exterior provide a convenient means for thus xing the pump in position.
As shown in my present drawings, A is the well-tube of an Artesian or similar well, having at the lower end a coupling, as at 2, with which is connected a tubular section 3, which is adapted to carry the latches by which the pump-cylinder 4 is locked in place.
5 is a sucker-rod, and 6 is the pump-plunger, which is fitted to move smoothly within the pump-cylinder 4E. The plunger is here shown in the form of a hollow cylinder having at the lower end a shoe 7, which has an interior conical opening converging from the bottom toward the top, as shown at 7. This is designed to concentrate the liquid and sand, which is generally mixed with it, from the outside toward the center and to measurably prevent the sand from entering between the plunger and its cylinder, and I thus relieve these parts of the rapid wear to which they are ordinarily subjected. This shoe is threaded and screwed upon the lower end of the plunger, and a similar shoe 8 is fitted to the upper end. The upper shoe has in a similar manner an outwardly-beveled interior, and both shoes can be at any time removed and replaced when worn, and as the great portion of the wear from sand and the like takes place near the ends of the plu-nger the body of the plunger will last much longer than the ends, so that by replacing these shoes as occasion demands the life of the plunger will be very considerably extended.
-The sucker-rod 5 is here shown as having a screw-threadedsocket which connects with a similarly-threaded extension, as at 9, this extension being a part of the cylindrical connection 10, which is screwed thereon to lit the interior of'the plunger, as shown, thus making all the parts easily separable when. required. The inlet-valve ofthe plunger is located at l1 and is here shown in the form of a ball closable upon a seat, as at 12. The stationary inlet-valve 13 is located in a cage 14 at the bottom of the plunger-cylinder 4, and the valve-seat 15 and cage are screwthreaded and fitted into the lower end of' the pump-cylinder so as to be easily removable.
The lpump-cylinder has a smaller diameter than the tube A and part 3 and is designed to be lowered through these parts until the pump-cylinder projects below the part 3, as shown.
The pump-cylinder is here shownas screwthreaded at the top and fitting a similarlythreaded section 16, having substantially the l length to lit within the part 3, and any suitable packing serves to make a joint between the parts 3 and 16. lThe part 3 has an annular groove or channel made in it, as shown at 17. In Figi I have shown this channel made on the inside of the part 3, and in Fig.` 2 I have shown it made upon the outside, the position of this channel depending upon the position of the latch.
In Fig. 1 the latches 18 are fixed within the part 16 and have tongues or lugs 19 projecting from them and adapted to engage with the groove or notch 17 when in line therewith. The latches are either elastic in themselves or may be spring-pressed, so that when IOO the Apump-cylinder has been lowered through the well-tube A until it reaches its operative position the projecting tongues or lugs 19 will simply slide down over the interior of the tube until they reach the channel 17, when the spring-pressure will force them out and lock thepump-cylinder in position. rlhe sucker or plunger rod 5 may then be reciprocated within the desired limits for pumping purposes as long as may be desired.
Whenever itis necessary or desirable to remove the pump from the well, the plungerrod is raised until the upper beveled edge of the shoe 8 of the plunger engages the lower projecting ends ofthe spring-latches, and when this engagement takes place these latches are drawn inwardly until the lugs 19 are disengaged from the slot 17, when the apparatus will withdraw the pump from the well.
As shown in Fig. 1, the latches being fixed to the interior of the section 16 or the pumpthe ends 20 are bent inwardly through open j slots or channels, so that their inner angles stand substantially in the line ofk movement of the plunger and are thus engaged and forced out by it when it arrives opposite to them, andthe device is thus freed and allowed to be moved through the well-casing.
Having thus described myinven-tion, what I claim, and desire to secure by Letters Patent, is-
1. In an Artesian or like well, the combination of a tube and a pump-cylinder one of which is channeled and the other provided with spring-pressed latches, said latches each having a member to engage the channel of the other part and thereby hold the cylinder to the tube; and means including a plunger and a member having an inclined surface carried thereby for withdrawing the latches and releasing the cylinder from the tube.
2. In an Artesian or like well, a tube, a pump-cylinder movable and adapted to be lowered to the bottom within said tube, one of said parts provided with a channel, springactuated latches lying parallel with the cylinder and having lateral projections intermediate of their ends adapted to engage said channel whereby the pump-cylinder is locked to the tube, a plunger movable in the pumpcylinder within the cylinder below the latching mechanism for pumping purposes, said plunger having its upper end adapted to disengage the latches when drawn into contact therewith, whereby the pump-cylinder may be removed bodily from the tube.
3. An Artesian or like well having a tube, a pump-cylinder, latching mechanism by which the cylinder is xed to the lower part of the tube, a valved plunger, and a rod by which it is reciprocated within the pump-cylinder, said plunger having detachable interiorlybeveled shoes fixed to the upperand lower ends thereof.
4. An Artesian or like well and tube therefor, a pump-cylinder movable within the tube, a latching device, one member of which is carried by the tube, and the other by the pump-cylinder whereby the two may be ixed together when the pump is in position for work, a plunger movable within the cylinder, said plunger having an interiorly-beveled cylindrical shoe fixed to its upper end, said shoe being adapted to disengage the latches when drawn into contact therewith so that the pump-cylinder and connected parts may be removed from the well.
5. An Artesan or like well having a tube, a pump-cylinder-latching mechanism by which the cylinder is x'ed to the lower part of the tube, a valved plunger, anda reciprocable rod, said plunger having a detachable interiorly-beveled shoe fixed to its upper end and adapted to release the latching mechanism.
In witness whereof I have hereunto set my hand.
