PUMP-ACTUATING MECHANISM.
I Application filed March 1, 1926.
This invention relates to improvements in deep well pumps and is a continuation in part of my copending application filed August 26, 1925, for pump operating mechanism, Serial No. 53,181.
In a prior Patent No. 1,550,110 granted August 18, 1925, I have described and claimed a pump in which a pair of pump rods are connected to cross heads and actuated from a crank shaft by means of levers provided with fulcrumsarranged above and below the crank shaft; In this device I further provide guide rods for the cross heads which extend above and below the crank shaft and receive the two cross heads.
In the present invention I provide a pump of similar construction in which the upper and lower cross heads are independently guided.
An object of the invention is to provide a construction in which separate guide rods are employed for the upper and lower cross heads providing a space between the adja cent ends of the guides which will permit removal of the cross head from the guide for disassembling without removing the frame.
A further object is to provide means for lubricating the guide rods and cross heads.
A further object of the invention is to provide a construction in which wear on the cross heads and guide rods may be compensated forby the use of shims which may be readily and easily placed in position between the cross head and the guide.
In the accompanying drawings I have shown one embodiment of the invention. In this showing,
Figure 1 is aside elevation, parts being shown in section,
Figure 2 is an end elevation,
Figure 3 is a perspective view,
Figure 4 is a plan view, parts being shown in section,
Figure 5 is a detail view of the lower end of one "of the guide rods showing the oiling mechanism,
Figure 6 is a detail view of the center portion of the lower cross head showing the arrangement of the pump rods, and,
Figure 7 is a similar view of one of thecross heads disassembled.
Referring to the drawings, the reference numeral 1 designates a main shaft which is provided witha crank portion 2. This Serial No. 91,599.
shaft is mounted in suitable bearings formed in a pair of side members 3 forming the frame or support for the pumping mecha nism and is driven from a suitable source of power by means of a gear a which meshes with a pinion 5 carried by a drive shaft 6. 69 As shown, the drive shaft is provided with a pulley and isadapted to receive a belt I (not shown) or other suitable drive mechaand are provided with arms 12 and 13 respectively which are slottedthroughout substantially their entire lengths and are adapted to receive a roller 14: carried by the crank portion of the shaft. Each of the levers is provided with a sleeve 15 for the reception of its fulcrum. The other arm of the bell crank lever is forked at its outer end providing a pair of arms 16 (see Figure 2).
These arms are adapted to be connected to the forked ends 17 of links 18 by means of pins 19. The links are provided with sleeves 20 on their other ends adapted to receive a pin 21 and the ends of this pin are received in sleeves 22 carried by substantially U-shaped guide members 23. The U-shaped members 23 are adapted to receive guide rods 24 which are oblong in cross section and which are secured to the inner faces of the frame bylmeans of bolts 25 or other suitable fastening elements. As shown the pin 21 is of a length slightly less than the distance between the guide rods 24. 1
Between the links 18 the pins 21 are enlarged and thelower part is provided with a threaded opening 26 adapted to receive the threaded end of a tubular pump rod 27. An inside pump rod 28 passes through the lower cross head and is surrounded'by suitable packing 29 retained in a packing gland formed in the cross head by means of a packing nut 30. As shown this pump rodextends upwardly and is connected to the upper cross head as at 81.
As shown the lowerguide rods terminate at a point below the crank shaft and; are of guide rods. are reached.
ent from the foregoing description.
a length suflicient to receive the lower'cross head during its reciprocation. The upper guide rods are similar and of a'length sufiicient to receive the upper cross head during its reciprocation and the adjacent ends of the guide rods are spaced from each other. This is a material advantage as it permits the removal of the cross heads and the censequent disassembling of the construction without removing the frame by moving the lower cross head upwardly, or the upper cross head downwardly until the ends of the By I providing the U-shapedmembers 23 on the opposite sides of the cross heads and the guide rods being rectangular in cross section, taking .up wear on the parts is materially simplified. As shownin Figure 5101" the drawings, shims 32 may be readily inserted between the cross head andjguides for this purpose. Adjacent the bottom of each of the guides I provide an oil pan 33 and the cross-heads are ,provided with depending resilient arms 34 which are adapted to dip into these pans vand then contact with the sides of the guides to lubricate the guide and the cross head.
The operation of the device will be appafi'- T e rocking movement'of the bell crank levers 10 and '11 caused by the movement of the roller 14 in the slotted arms 12 and 13 imp arts reciprocating motion through the links 18 to the pump rods27 and 28. The greater partof the movement of one of said pump rods-in either direction is accompanied by a movement of the other rod in the opposite direction. I
During each revolution of the crank shaft 1," the following conditions are'successively created; Following the cycle from the posi- 'tionof; the crank shaft shown in Figure. 1
thejlever 10 connected to the pump rod 28 is at thetermination of its downward move ment and about to commence 1ts upstroke while the lever '11 connected to the pump rod 27 is approaching the end of its upstroke with decreasing speed. The .up stroke of the rod 28 is then initiated with increasing speed and maximum of power "application, an upward movement of pump rod 19 continues until the crank shaft isat right; angles to cation.
the slotted arm '13,-whereupon downward movementof the pump"rod 27 beginsatincreasing speed and decreasing power appli- 'lVhen the'crank shaft reachesthe limit of its downward movement the slotted. arms 12 and '13 are located opposite each other, pump rod 27 is approaching the mid die of, its downward movement and traveling at the greatest speed attained it at any time during a'c'ycle and pump rod- 28has p'assed the 'middle of its upward stroke and is moving less rapidly and with greater-effectivenessof power-f operationthan rod 19. As the crank-shaft continues its revolution in a counter clockwise direction and moves upwardly the pump rod 27 approaches the termination of its downwardstroke at decreasing speed while pump rod 28 approaches the termination of its upward stroke at increasing speed. As the crankshaft'passes the position in which it is at right angles to the slotted, arm 13 downward movement of rod 27 is changed to upwardmoveinent at increasing speed of power application and upward movement of rod 28 continues at decreasing spceduntil it reachesthe end of its stroke when the crankshaft passes right angles to the slotted arm. 12 of the upper lever. During the remainder of the stroke the same mechanical.principle applies as during the first half.
It will thus be; seen that reversal, of the directionof movement of the two rods does not take place. at the same-time, but, at the endof the stroke the two, rods are moving in the same direction and thus do :not reach the middle of their respective strokes, at, the same time. Furthermore, the two pump rods never travel at thesame speed or with the. same. effectiveness of power application: except for the infinitesimal period between movement of the two rods ,in the same .direc- .tion.
It is to be understood that the form of the invention herewith shown and described,
