NORMAN 0. FLEMING, OF HUNTINGTON PARK, CALIFORNIA.

DEEP-WELL PUMP.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed. February 19, 1918. Serial No. 218,167.

To all whom it may concern:

Be it known that I, NORMAN O. FLEMING, a citizen of the United States, residing at Huntington Park, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Deep- Well Pumps, of which the following is a specification.

My invention relates to the art of pumping water, and more particularly to pumps which are adapted to handle considerable quantities of water from medium or considerable depths. The invention resides in the novel combination and association of parts as set forth in the accompanying description and shown on the annexed draw- 111 s.

Tn these drawings, which are for illustrative purposes only,

Figure 1 is a side elevation partly in section of one embodiment of my invention.

Fig. 2 is a front view partly in section on a plane represented by the line 2-2 of Fig. 1.

Fig. 3 is a front elevation of the pump with the buckets at one extreme position, all parts behind a plane represented by the line 33 of Fig. 1 being omitted for the sake of clearness.

Fig. 4 is a similar view of the pump with the buckets in their other extreme position.

Fig. 5 is a detail of a link.

Fig. 6 is a detail of a guide takeup.

In the form of my invention illustrated in these drawings, a frame 11 is employed,

this frame being composed of two lower members 12 and two upper members 13 held together with spacing rods 14. Turning freely in journals 15 is a countershaft 16 which carries a belt wheel 17 at one end and a pinion 18 at the other. The pinion 18 meshes with a gear 20 which is secured to one end of a three-crank-pin-twobearing crankshaft 21. The crankshaft 21 turns freely in journals 22 secured to the frame 11.

Pivoted on each of the two outer crank pins is a lower connecting rod 23 and pivoted on the center crank pin is an upper connecting rod 24. The lower rods 23 are pivoted on a lower wrist pin 25 carried in a lower beam 26 which is in turn free to turn on a pin 27. The upper rod 24 is pivoted on a wrist pin 28 carried in an upper beam 29 pivoted on a pin 30. The pins 27 and 30 Each of the beams 26 and 29 carries at its outer end a link pin 31 on which one end of a link 32 is pivoted, the other end of said link being pivoted on a crosshead pin 33 carried in an upper crosshead 34 or a lower crosshead 35.

Each of the crossheads 34 and 35 consists of a body 36 in which the pin 33 is secured and a pair of guide plates 37 which are secured to the body 36 by bolts 38 and which straddle vertical guides 39 carried in a frame 40. The frame 40 is bolted or other wise rigidly secured to the frame 11. The pins 31 project outside the beams 26 and 29 and are provided with an external thread on which beam guides 41 are threaded, these beam guides each having a set screw so placed as to engage the pins 31 and prevent guides 41 from turning on the pins 31, as shown in Fig. 6. The proportions of the parts is such that the pins 31 at all points in their stroke are inside and between the guides 39. The beam guides are adjusted on the pins 31 so that they engage but slide freely between the guides 39, it being possible to adjust the beam guides 41 at any time to take up any wear thereon or on the guides 39. By using the beam guides 41 and so placing them that they engage the guides 39, the outer end of the beams 26 are guided to take care of any side strains thereon.

Threaded in the body 36 of the upper crosshead 34 is an inner rod 50, this rod passing through a stuffing box 51 in the lower body 36 to which an outer rod 52 is secured. The rods 50 and 52 pass downwardly into the well through a discharge T 53 secured to the top of the pump column 54.

The frame 11 is mounted on a base 60, being secured thereto by means of bolts 61. Formed on the lower members 12 are housings 62 in which roller blocks 63 are placed, these roller blocks sliding up and down and being actuated by screws 64. Turning freely in a cavity 65 in the bottom of each block 63 is a roller 66, this roller providing a ready means for sliding the frame 11 over on the base when the bolts 61 are removed and the screws 64 are used to force the blocks 65 down.

The method of operation is as follows:

Power being applied to the shaft 16 by means of a belt, not shown, on the belt wheel 17, the shaft 16 turns the shaft 21 through the pinion 18 and the gear 20 which are of any practical desired ratio to suit the pump speed and the speed of the driving means.

The rotation of the crank shaft 21 drives the beams 26 and 29 through the rods 23 and Qt, the beams moving from the position shown in full lines in Fig. l to the position shown in dotted lines in that figure. This movement of the beams 26 and 29 reciprocates the crossheads 3i and and reciprocates the rods 50 and 52. The rods 50 and 52 are in turn connected to suitable buckets, not shown, in a pump barrel, also not shown, in accordance with standard practice in duplex two bucket pumps.

What I claim is l. A duplex deep well pump comprising a frame; upper and lower beams located in the same plane; pins on which said beams are pivoted; said pins being parallel to each other and secured in said frame; a crank shaft having three crank pins, said crank shaft being located between said beams and journaled in said frame; means for driving said crank shaft; a pair of connecting rods each journaled at one end on one of the outer crank pins of said crank shaft; a wrist pin secured in one of said beams on which the other end of both of said pair of connecting rods is journaled; a single con- Gopies of this patent may be obtained for necting rod journaled on the center crank pin of said crank shaft; a wrist pin secured in the other of said beams on which said single connecting rod is j ournaled; and linkages for connecting the free end of each of said beams with the buckets of the pump.

:2; A pump as in claim 1 also comprising vertical guides secured to said frame between which the free ends of said beams travel; and takeup means on said free ends forengaging said guides.

3. A pump as in claim 2 in which eachof said takeup means comprises a pump rod pin secured in the free end of one of said.

beams and projecting outwardly at either side of saidfbeam said projecting ends being threaded; beam guides threaded on said projecting ends; and means for preventing said guides from turning on said pin.

4:. A pump as in claim 3 in which said linkages each comprisea crosshead engaging but sliding freely on said vertical guides; and a link pivoted at one end on said pump rod pin and at the other end on a pin carried in said crosshead.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this five cents each, by addressing the Commissioner of latents, Washington, I). G.
