Definitions
- This invention relates to pumplng maehinery and is particularly designed for use in connection with a deep. well pump.
- My improved pump comprises 'two plungers located in the well one above the other, adapted to lift the water alternately, the operating rod for one of said plungers being hollow so that the other operating rod may work inside of the first.
- both plungers are moving upward.
- one plunger begins to move upward with the stream of water before the end of the upward stroke of the other plunger, with the result that the water is forced upward in a continuous stream without being permitted to come to rest.
- This obviates the necessity for giving the stream of water a fresh start at the beginning of the stroke of each plunger, and thus materiallyv lessens the strain upon the pumping machinery.
- Another object of my invention is to provide a new and improved arrangement 'of parts by which the power is applied directly in line with the plunger-rods so as to avoid any side draft which would cramp the mechanism and make necessary the use of an undue amount of energy for raising a given quantity of water.

Specification of Letters Patent.
Patented Oct. 26, 1915.
Application filed September 18, 1911. Serial No. 649,843.
ery, of which the following is a specification,
reference being had to the accompanying drawlngs.
This invention relates to pumplng maehinery and is particularly designed for use in connection with a deep. well pump.
My improved pump comprises 'two plungers located in the well one above the other, adapted to lift the water alternately, the operating rod for one of said plungers being hollow so that the other operating rod may work inside of the first.
It is one of the objects of my invention to provide a new and improved means for causing the upward stroke of each plunger to occupy a greater proportion of the time than does the downward stroke. In this way, for an interval just after one of the plungers has reached its lowermost point, both plungers are moving upward. Thus one plunger begins to move upward with the stream of water before the end of the upward stroke of the other plunger, with the result that the water is forced upward in a continuous stream without being permitted to come to rest. This obviates the necessity for giving the stream of water a fresh start at the beginning of the stroke of each plunger, and thus materiallyv lessens the strain upon the pumping machinery.
Another object of my invention is to provide a new and improved arrangement 'of parts by which the power is applied directly in line with the plunger-rods so as to avoid any side draft which would cramp the mechanism and make necessary the use of an undue amount of energy for raising a given quantity of water.
Another object of my invention is the provision of means for relieving all possible strain from the plunger-rods in the well by means of force pumps located at or near the surface by which the water maybe delivered to the elevation required after being brought to the surface without requiring this work to be done by the lifting plunger-s.
It is another object of my invention to provide suitable mechanism and such an arrangement of parts that, withoutchanging the position of the pump on its foundation, the driving crank shaft may be utilized to advantage for hoisting the plunger-rods cut of the well for repairs.
Another object is the improvement of pumplng machinery in sundry details hereinafter pointed out.
The means by which I have accomplished these objects are illustrated in the drawings and hereinafter specifically described.
That which I believe to be new is set forth in the claims.
In the drawings :-Figure 1 is a side view of my improved machine; Fig. 2 is a top or plan view of the same; Fig. 3 is afront View of my device; Fig. i is a rear view thereof; Fig. 5 is an enlarged detail, being a cross-sectiontaken on line 5-5 of Fig. 1; Fig. 6 is an enlarged detail, being a section taken on'line 66 of Fig. 2; Fig. 7 is an enlarged detail of my improved crank; and Fig. 8 is an enlarged detail being a top view, partly broken away, of the parts shown in Fig. 7.
Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters- 20 indicates the base located upon a foundation 21 built about the upper end 22 of the well tube.
23- 24: indicates standards, mounted in the upper ends of which is a crank 25, said crank comprising cylindrical parts 26-27 revoluble in bearings 2829.
30 indicatesa gear bolted or otherwise suitably secured to a central cylindrical part 31 of said crank.
32 indicates a shaft ournaled in said frame in rear of said crank 25, mounted upon which is a gear 33 meshing with said gear 30.
3 f indicates a driving pulley mounted on said shaft 32, the outer end of said shaft be ing supported by any suitable bearing not shown. a 1
35-36 indicate uprights bolted or other wise rigidly secured to'the base 20.
' 37 indicates a rod passing through said uprights 35-36 and mounted at its ends in said standards 23-24:.
38 indicates washers or other suitable spacing blocks mounted on said rod 37, by which the uprights 363 7 are held firmly in position. A
39-40 indicate levers pivotally connected V at their rear ends to the upper ends of said u 42 .of one of .the levers 39-40. Each slideuprights 35-36, each of said levers, as best shown in'Figs. 1 and 6, comprising two bars 41-42 spaced a distance apart by suitable blocks 48-44. 45-46 indicate slide-blocks each adapted to slide between the bars 41- block 45-46 embraces one of the wristeonnections 47-48 ofth e crank 25. It will thus be seen that whenever the driving wheel 34 isrotated by the application of suitable power the levers 39-40 are caused to rise and fallalternately.
19-50 indicate arms or links, pivotally mounted at their lower ends'upon the base 20, to the upper ends of which are pivotally secured two levers 51-52. As best shown inFig. 2, these levers 51-52 converge lat erally toward their forward ends where they are connected, as hereinafter described, to the op eratmg -ro'ds leading to the plungers.
53" indicates a link pivotally connected at its lower end to the lever 51 and pivotally connected at its upperend to the forward end of the lever 89.
54 indicates-a link pivotally connected at its upper end to the lever 52 and pivotally connected. at its lower end to the forward end of the lever 40. h
55-56 indicate guide-rods mounted at the forward end of the machine in bosses 57 mounted on plates 57 suitably secured to the base 20.
58 indicates bars extending forward from the upper ends of the standards 23 A, em-
bracing at their forward ends the guide-rods 59 indicates diagonal brace-rods extending from the upper ends of the standards 23-24 to the upper ends of the guide-rods 55-56. 60 indicates'a cross bar connecting the upper ends of the guide-rods 55-56.
61-62 indicate cross-heads slidably mounted upon the guide-rods 55-56, the crosshead 61 being pivotally connected to the forwardend of thelever 52, and the cross-head 62 being pivotally connected to the forward end of the lever 51. As best shown in F 3,;the cross-head 62 is connected at its middle point to the hollow'plunger-rod 63.01? the pump, and the cross-head 61 is connected at its middle point'to the plunger-rod 6% which is located inside of and adapted to slide' freely within the hollow plungerrod 63.
65 indicates a guide and packing -head in the, upper end of the well-tube 22 for the plunged-rod 63, provided with the usual follower 65" forholding packing properly in position.
' The operation of my improved machine is as folloWs;-lVith the drive wheel 34 driven by any suitable power, in the'direction indicated by the arrow thereon in Fig; 1, the gear-30 and crank 25 will be driven in the will be at right angles .the lever 51 is,
direction indicated by the arrow on said gear. lVhen the wrist-connection 47, in the rotation of the crank, reaches the position indicated by the dotted line O-A, the crank to the lever 39 and the lever will have reached its highest point. When, thereafter, the wrist 47 reaches the position indicated by the line ()-B said crank will again be at right angles to the lever and the lever will be in its lowermost position. Thus in the rotation of the crank 25 the lever 39is being raised while the crank is moving from the line 0-13 to the line O-A, and said crank is descending during the shorter period of time while the crank is moving from the line ()-A to the line O-BQ In the construction shown the angle A-O-B equals approximately H0".
In like manner it will be noted that the lever 40, actuated by the wrist-connection 16, also reaches its lowermost point when the crank stands in the position indicated by O-B and in its highest position when the crankreaches the position indicated by the when the lever 39 is moved downward to the position indicated by the dotted line P-C, through the medium of the link also moved downward to the position indicated by the line R-D, the crosshead 62 causing the forward end of the lever 51 to move in a vertical line, this being made possible by the pivoting of the link 49, such lever being pulled forward to the position indicated by the line R-E. Likewise when the lever 39 reaches the position P-F the lever 51 will have reached the position R-G with the lever 49 again in substantially the position R-E. In the same way when the lever 40 is raised and lowered the lever is given a slight movement longitiulinally of itself to permit the forward end of the lever 52 to move always in a vertical line upon the guides 55-56.
As best shown in Fig. 5, the crank 25 is provided at its ends, outside of the frames 23-24, with wrists 66-67, upon which are mounted the upper ends of piston rods 68-69 provided at their lower ends with pistons 70-71 which work in cylinders 72-73 for forcing the water to any desired point after it has been raised to the surface of the ground.
74 indicates a hoisting the crank 25, wrist 66,
drum connected to through the medium of the in concentric relation thereto.
This drum is provided for use in lowering the plungera-ods into or raising them out of the well, being used in practice in connection with any suitable derrick not shown, this being possible by reason of the levers 5152 and the cross-heads 61(32 being mounted so that they may be readily moved out of the way when disconnected from the plunger-rods. I i
By my construction I have provided a. crank which takes up a minimum amount of space by reason of having two of the crankarms made in circular form so as to be utilized as bearings by which the crank is journaled in the frame, and by having the third crank-arm made in circular form so as to be utilized as the hub for the driving gear. This makes a very strong, compact, shaft, with the bearings close to the crank portions and with the crank as a whole, therefore, Well balanced.
By arranging my levers 5152 diagonally of the frame and having them converge laterally into vertical alinement at their front ends and by having their forward ends slide upon the vertical guides 55-56, I provide a very efficient power-transforming mechanism which is especially valuable in a pump of this type.
The levers 51-52 have been described as having movement longitudinally of themselves, and by this I mean the longitudinal movement of the lever such as is attained by the swinging of the lever in such a way as to keep its free end constantly in a direct ver-,
tical path, as distinguished from the longitudinal movement of the lever swinging upon a fixed pivot. The claims are therefore to be construed accordingly.
