PUMP.

SPECIFICATION forming part of Letters Patent No. 759,080, dated May 3, 1904. Application filed January 11, 1904. Serial No. 188,480. No model.)

i 0 all wk/077v it may concern:

Be it known that I, PHILIP H. DEIS, a citizen of the United States, residing in \Vashington, in the District of Columbia, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 'it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to pumps; and it has reference particularly to pumps having me chanical means for operating them, so as to make them available for farm, irrigating, cattle-watering, and other similar purposes where the saving of the attention required to keep the pump operating is peculiarly valuable.

The invention has in view the employment of a simple mechanical means for furnishing the power necessary to reciprocate thesuckerrod or corresponding element, and in order to conserve simplicity, inexpensiveness, and durability in the said means the invention contemplates a novel and effective means for regulating the action of the power-furnishing means and for also diminishing on the upstroke the eii'ect of gravity action on said sucker-rod, the parts it carries, and the body of water in said conducting means which is being sustained by said sucker-rod and its cooperating parts.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is a view, partly in side elevation and partly in vertical section, of my improved pump, showing one form of means for diminishing the effect of gravity action on the sucker-rod, its cooperating parts, and the body of water sustained thereby on each upstroke.

Fig. 2 is a view in side elevation, somewhat enlarged, of the means for reciprocating the sucker-rod. Fig. 3 is a top plan view of what is seen in Fig. 2. Fig. 4 is a view substantially like Fig. 1 except that it shows another form of means for diminishing the effect of gravity action on the sucker-rod, its cooperating parts, and the body of water sustained thereby on each upstroke. Flg. 5 is an en- I larged detail view, partly in section and partly in side elevation, of a part of the structure which is disposed near the bottom of the well, a certain one of two valves, 43, and its innuediate sustaining means being turned a quarter 7 of a revolution relatively to the other to clearly show the construction thereof; and Fig. 6 is a modiiied form of the means for reciprocating the sucker-rod.

In said drawings, a designates the main or well pipe, which projects down through a platform 5 at the mouth of the well 0 and into the latter in the usual manner, and (Z is the suckerrod.

On a staging e in the well is mounted a tank j, which by virtue of having a central tubular portion .is of annular form in plan. This tank is partially filled with water, which tends to displace a Heat 7), which surrounds the tubular portion g] and is air-tight. This float carries a pair of rods '1', which are bolted or otherwise secured thereto at their lower ends and at their upper ends are held in fixed relation with the sucker-rod (Z by means of a cross-piece j, secured by nuts I, arranged above and below the cross-piece on the rods '27 and (Z. The buoyancy of the float tends to sustain the sucker-rod (Z and the weight of wa ter which by themeans which said sucker-rod carries and which will be hereinafter described said. sucker-rod sustains by adjusting the size of the float 71 to the weight of the column of water sustained by the sucker-rod the said column oi water and its sustaining means may be balanced by the float, so that practically all that the means which reciprocates the sucker-rod will have to do will be to lift simply so much of the water as is discharged at each upthrust of the sucker-rod.

In the modification shown in F 4,whereiu involved the preferred form of a balancing means, a weight-carrier Z is sustained by the free end of a rope, chain, or the like on, extending over a sheave w, journaled in a bracket 0, carried by the pipe at or otherwise sustained,

the other end of the rope being connected to an eye 19 at the upper end of the sucker-rod (I. On the weight-carrier may be placed weights q, as many in number as the weight of the column of water in the well-pipe requires in" order to maintain the balance.

As an inexpensive, reliable, and generallyobtainable means for reciprocating the suckerrod the driving mechanism shown in Figs. 1 to 4 may be employed. This comprises side frames '2', connected by braces s, a crank-shaft t, from which the reciprocating motion is imparted to the water-lifting means, a drum n, on which is wound a rope, chain, or the like a weight w, attached to the free end of said rope and suspended thereby from the drum free to effect the rotation of the drum by unwinding the rope, and means for transmitting the rotary motion of the drum to the crank shaft t. In the adaptation illustrated said last-named mechanism comprises a gear a, fixed on the drum-carrying shaft a pinion z, meshing with gear a; and fixed on a shaft 1, a gear 2, also fixed on shaft 1, a pinion 3, meshing with gear 2 and fixed on a shaft 4, a gear 5, also fixed on shaft 4, a pinion 6, meshing with gear 5 and fixed on a shaft 7, a gear 8, also fixed on shaft 7 and a pinion 9 on the shaft t. This last-named pinion is free to turn on the shaft t and has formed with it one member 10 of a clutch, the other member, 11, of which is splined on the shaft, so as to be movable either into engagement with the clutch member 10 or out of engagement there with against a stop-collar 12. The 'clutch is useful as a disconnective connecting means between shaft 2, and the mechanism whereby the power is transmitted from shaft y. hen the rope has completely unwound itself from the drum, the clutch members may be disengaged, so that when the rope is being rewound on the drum, as by a crank 13, attachable to shaft 7, pinion 9 can rotate without driving shaft 2. A ratchet 14 and pawl 15 are employed to obviate back action of the mechanism in rewinding.

The shaft t may be directly connected by a pitman with the sucker-rod (Z; but I prefer to interpose a means whereby the action of the apparatus may be regulated, and to this end I may and preferably do employ the mechanism seen best in Fig. 2. Here 16 and 17 are a pair of levers fulcrumed in a bracket 18, which form a part of one of the side frames and pivotally connected by a link 19, the pivoting-pins 20 for which may be applied in any of the holes 21 in the levers. A pitman 22 connects the free end of lever 17 with the crank-pin 23 on a balance-wheel 24, which shaft t carries, and another pitman 25 may connect the free end of the lever 16 with one of the braces 26 for rods 1'. The connection between the pitman 25 and lever 16 is in the form of a block 27, arranged in a slot 28 in the lever and adapted to be adjusted by a thumb-screw 29, mounted in the lever and swiveled in the block. By this mechanism the action of the pump can be regulated not only to a nicety, but with the greatest facility.

In place of the driving means just described an electric motor 30 may be employed. In Fig. 6 this is shown mounted between the side frames and coupled with shaft tthrough gear members 31, 32, and

The water-lifting means proper is best seen in Fig. 4. The lower end of the well-pipe communicates with a chamber 35, from which extend downwardly pipes 36 and 37, each open at the bottom. Pipe 36 is shown alined with the well-pipe. Pipes 37 are preferably two in number and are the intakes from the well, each having a strainer 38. The suckerrod extends through chamber down into pipe 36 and carries in said pipe a piston 39. Secured on the sucker-rod in chamber 35 is a cross-arm 40, carrying valve-stems 41, each projecting down into a pipe 37 and provided with the stirrup portion 42 of cylindrical valved pistons 43, having flexible flaps 44, adapted to open upwardly. Each pipe is provided above and below the valve 43 with an upwardly-opening valve, the upper one being shown as a disk 45, seating on the top of the pipe, and the lower one as a flap 46, seating on a shoulder 47. The piston 39 and valves 43 have annular channels 48, forming waterpacking, and the piston is also provided with a flexible cap 49 at its lower end, which has its edge chamfered off, as at 50, to prevent downward escape of water past the piston. In the operation of this means the valved pistons directly act to draw the water from the well into the water-conducting means, which latter comprises pipe a, chamber 35, and what may be regarded as its extension, pipe 36. They also of course act upon each upstroke to effect the lifting of the body of water standing in the conducting means after the preceding downstroke. Under normal conditions the water in the well stands at a height where chamber 35 will be partly submerged. This brings the piston below this level, with the consequence that sincepipe 36 is open at the bottom the piston in effect works up and down in the well-water and acts to impart a regulating effect to the driving means. This regulating effect is dependent, in part at least, upon the fact that since the piston stands confined at all times between two bodies of water, one above and the other relatively below it, it is required just at the moment of change of stroke in either direction to overcome the inertia of that one of said bodies toward which it is next directed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a vertical water-con- IIO ducting means open at the bottom and having upwardl v-opening valved inlets affording access from the well thereto above the bottom opening, a sueker-rod, a piston disposed in said conducting means relatively below the valved inletsand connected to said sucker-rod, and a means for forcing water into said conducting means at the inlets also connected to said sucker-rod.

2. The combination of a vertical Water-conducting means open at the bottom and having upwardly-opening valved inlets aifording access from the well thereto above the bottom opening, a sucker-rod, a piston disposed in said conducting means relatively below the valved inlets and connected to said sucker-rod, a means for forcing water into said conducting means at the inlets also connected to said si1cler-rod and means for reciprocating the sucker-rod.

3. The combination of a vertical water-conducting means open at the bottom and having upwardlyo )ening valved inlets affording access from the well thereto above the bottom opening, a sucker-rod, a piston disposed in said conducting means relatively below the valved inlets and connected to said sucker-rod, a means for forcing water into said conducting means at the inlets also connected to said sucker-rod, and means, also connected to said sucker-rod, for diminishing the effect of gravity action on said sucker-rod, the piston, the water-forcing-in means and the body of Water which stands in said cont looting means above the piston and said Water-forcing-in means.

In testimony that 1 claim the foregoing l have hereunto set my hand this 5th day of January, 1904.
