PUMP.

SPECIFICATION formingpart of Letters Patent No. 687,375, dated November 26, 1901. Applitation filed August 2, 1899- $erial No. 725,826 (No model.)

To all whom it may concern.

Be it known that I, OHARLEsB. HARB'ERT, a citizen of the United States, residing at Norman, in the Territory of Oklahoma, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

My invention has for its object to improve pumps, and more particularly double-acting pumps which are designed to be used in Arte'sia'n or drilled Wells of small cross-sectional area as compared with dug wells; and it consists in improvements in the construction of the parts of the pump to be hereinafter pointed out, whereby efticiency of operation and compactness of arrangement are attained.

In the accompanying drawings, Figure 1 is an elevation of one form of the pump, partly in vertical section. Fig. 2 is a horizontal sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a sectional elevation of the lower portion of a different form of my pump. Fig. 4 is'a horizontal section taken on the line 5 5 of Fig. 3.

In many parts of the country potable wa ter can only be obtained from deep wells, which are usually sunk by means of drillingmachines and then cased with iron tubing or pipe. The question of expense usually makes it necessary that such wells should be comparatively small in cross-sectional area, a

five-inch (5) casing being a size commonly employed in such wells.

In many of such wells the water stands at a normal level many feet below the surface, and it has therefore been a question of no little difficulty to obtain a pump which could be located in the limited space within the casing of adeep well and to have it simple in construction and efficient in operation. The forms of pump which I have invented and herein shown are so compact in construction as to be easily arranged in a five-inch casing and are simple in construction and easily operated.

In the drawings, A represents the casing of a deep well.

B represents the platform surrounding the mouth of thewell, from which platform rises a post or support 0, to which is fulcrumed the operating-lever D.

2 2 represent pipes or tubes which extend from the top of the well down to and below the water-level and serve as the dischargepipes through which the water is conducted to the surface. They are provided at their upper ends with curved necks, whereby the water is directed as may be desired. The two pipes are connected by links with the two arms, respectively, of the operating-lever D.

The links 4 are connected with split rings 5, which are secured to the pipes or tubes 2 by means of set or clamping screws 6.

Referring now particularly to the form of my invention shown in Figs. 1 and 2, 7 7 in dicate a, pair of cylinders mounted in the lower portion of the casing-that is to say, below the normal water-levelwhere they are securely held. I prefer to hold these cylinders in place by means ofa clamping or gripping device, preferably consisting of a pair of elastic arms secured to the cylinders and provided with grip-faces 9,which are arranged to engage with the interior walls of the casing with suflicient force to hold the cylinders firmly in place. 10 indicates a chain or flexible connection extending from the arms of the said clamping or gripping device to the top of the well. It will be understood that by pulling upon the chain the arms 10 will be drawn inward and out of engagement with the walls of the casing, after which the cylinders 7 may be removed from the well should repairs be necessary.

The means which I have described for holding the stationary lower parts of the pump in place are preferably arranged above such parts and are of small cross-sectional area as compared with the cross-area of the well, so that they do not to any material extent interfere with the free flow of the water to the discharge-pipes. The arms of the clamping device extend outward to the walls of the easing between the discharge-pipes and above the stationary parts of the pump apparatus, which latter parts serve to close the lower ends of the discharge pipes and have telescopic engagement with the latter.

The upper ends of'the cylinders 7 are provided with openings 11, through which the water enters the cylinders, and these openings are controlled by valves 12. I prefer to employ ball-valves so arranged as to permit a free flow of water inward into the cylinders,

.but which prevent back or outward flow therefrom.

The lower ends of the discharge-pipes 2 are curved, as indicated at 13, and terminate in a short vertically-disposed section 14, preferably parallel with the pipe 2, which enters one of the cylinders 7 from the lower 'end, it being for that purpose open-ended. The u pper end of the section 14 of the pipe is packed or otherwise fitted to work water-tight in the cylinder and constitutes the piston of the pump. A valve 16, preferably of the ball variety, is mounted in the section 14 of the discharge pipe or tube and is so arranged as to allow free passage of the water from the cylinder 7 into the tube 2, but prevent water moving in the opposite direction.

It will be understood that the connection of each pipe 2 with its cylinder 7 is identical with the connection of the other pipe with its cylinder, so thata detailed description of both is unnecessary.

The two cylinders 7 are arranged side by side and are united together firmly, as by means of the encircling bands 17. I prefer to arrange the two pipes 2 2 upon opposite sides of the united cylinders 7 7 and as close to them as they can conveniently be arranged and work satisfactorily. By reference to Fig. 2 of the drawings it will be seen that the vertical planes which cut the two tubes 2 2 and the two cylinders 7 7 axially cross each other at right angles. This arrangement brings together the working parts of the pump in the most compact manner possible and yet does not in any wise interfere with the efficiency of the pump or the ease with which it may be operated.

In the construction shown in Figs. 3 and 4 I secure the same advantages of compactness and arrangement that are incident to the construction just described, as well as the same advantages of balance in the movements of the parts to be presently set forth. Referring to such figures, 7 7 represent a pair of plungers which are secured in the casing of the well and are arranged side by side in a manner similar to the arrangement and method of support of the cylinders 7 of the other construction. The short vertically-disposed sections 14 of the discharge-pipes 2 are arranged to slide over the plungers 7, being provided at their upper ends with packing 15 to cause the joints between them and the plungers to be water-tight. The section 14 is preferably continued downward alittle below the bent portion 13, connecting it with the pipe 2, as indicated at 14, and is there provided with an inlet-opening which is controlled by the valve 12'. 16 indicates a valve in the pipe 2, operating to prevent backtlow of water from such pipe.

The operation of the two forms of my invention is very similar. When one of the discharge-tubes 2 is moved downward by the operation of the handle D, water enters the cyl-- inder 7 freely through the opening 11, following the piston 15 as it moves away from such opening. During this movement the valve 16 in the discharge-pipe or the extension 14 thereof is held closed by the weight of the water in the tube 2. When the direction of movement is reversed and the pipe 2 moved upward, the valve 12 is instantly seated and prevents any backfiow of water from the cylinder, and the water which was taken into the cylinder on the other stroke or movement of the pipe is forced to enter the discharge-tube past the valve 16, and at the same time an amount of water equal to that which enters the discharge-tube from the cylinder 7 is delivered through the spout 3. stood that a very similar operation takes place in the construction of pump shown in Figs. 4 and 5. When the pipe 2descends, water enters the section 14 14, passing the valve 12' freely, backtlow from the tube 2 being prevented by the valve 16. On the reverse movement of the tube the plunger 7 enters the tubesection 14 14, and the valve 12, closing, forces the water from such tube-section into the pipe 2 and causes a corresponding discharge through the nozzle 3.

It will be observed that each of the forms of my invention shown and described in this case includes parts or members which are secured together and are firmly secured in the lower part of the well independently of the It will be under-- discharge pipes or tubes, which parts or members close the ends of the reciprocatory discharge-tubes, which latterhave telescopic engagement with the said stationary parts or members of the pump.

It will be readily understood that when the two pump-tubes 2 2 are connected with the opposite arms of an operating-lever in the manner shown and described the weights of the moving parts of the two independent pumps are opposed to each other and balance each other. This renders the operation of the pump very easy. As has been stated, .this balancing of the movements and weights of the two independent parts of the pump is incident to both constructions shown.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

In a pump, the combination of two discharge-pipes which have their lower ends curved, as indicated at 13, and terminate in short vertically-disposed sections 14, which latter have open ends, meansfor reciprocating the discharge-pipes alternately, members or parts located in the well for closing the lower open ends of the said discharge-pipes, and with which the discharge-pipes have telescopic engagement, elastic or spring arms secured to the said parts or members and adapted to engage with the inner walls of the welllining to hold the said part-s firmly in place and situated above the said parts which they hold and extending outward between the discharge-pipes, and suitable valves, substantially as set forth.
