CHARLES HENRY FOX, OF BAKERSFIELD, CALIFORNIA.

YUM?.

Application filed October 5,

To all whom t may concern:

Be it known that I, CHARLns H. Fox, a citizen of the United States, residing at Bakersfield, in the county of Kern and State of California, have invented new and useful Improvements in Pumps, of which the following is a specification.

My invention relates to fluid pumps, and more particularly to pumps of that type in which the explosion of a combustible mixture is utilized for advancing the fluid to be pumped.

One of the important objects of my invention is to provide improved means for utilizingthe explosive power of the fuel mixture whereby the same is transmitted to the fluid to be pumped without any dissipation or loss of energy.

A further object of the invention is to provide a device of the character described in which the explosive means acts to cause a practically continuous flow of the fluid being pumped.

EL still further object of the invention is to provide a pump of this character with means for compressing the fuel charge prior to its introduction into the explosion chamber, whereby a more rapid and efficient operation is made possible.

Other objects and advantages of my invention will be apparent from the following description, and the novel features will be pointed out in the claims.

Referring more specifically to the drawings, the numeral 1 indicates the casing of a well in which my invention may be used. The numeral 2 indicates what may be termed the pump cylinder, from which the water or other iiuid is forced upwardly through a discharge pipe 3, provided at its upper end with an outlet 4. The pump may be supported in any suitable manner from a. base .5 at the mouth of the well, and it is one of the purposes of my invention to introduce an explosive mixture into the cylinder 2, by means to be hereinafter described, there to explode the mixture, and by the force of the explosion, deliver the water into the pipe 3.

For the purpose of supplying a suitable device, which, as shown, comprises a shaft 6 suitably mounted on a base 7 and driven by a small motor or other source of power. rlihe shaft 6 operates a compressor 8lwhich draws in the charge through a carbureter 9, the gasoline being` supplied from a tank l0. This fuel mixture is ted from the compressor through a pipe ll, and suitable pipes l2 and 13, to one or the other ot the valve chambers 11i, through which the mixture is ted at the proper time into the respect-ive explosion chambers.

lithineach pipe l2 and 13 is a tubular valve-operating' rod le, which is operated at the proper time by means of a cam l@ carried by the shaft 17, which is rotated by means of lgearing i3 troni the shaft 6. The rod l is provided at its lower end with an enlarged head 19 within the chamber la, and to the head 19 is secured a cage 20, within which is reciprocally mounted a comparatively long stem 2l of the valve 22, which cooperates with the seat 23 to cut ott or admit the Jfuel mixture into the explosion chamber. The stem 2l is provided near its `upper end with a stop nut 2t, which is normally held in its uppermost position by the spring 25, and in the position shown in Fig. 8 rests against the seat 26.

Within the stem 2l is reci proc-ally mounted an electric conducting` medium 27, which is insulated by a sleeve 2S and carries at its lower end an electrode 29, which cooperates with the adjustable screw to provide an ignition spark at the proper time, the screw 30 being supported by a bracket 3l secured at the lower end ot the casing. The member 27 is urged downwardly by a spring 32, which connects the electrode to a source of electricityy tireugh a wire 33, which is insulated as shown at 34.

In Fig. 9, the valve 22 is shown in the position in which the fuel is being admitted to the explosion chamber. .flotter the luel has been admitted, the rod l5 is raise-d and the valve 22 is closed through the medium of a spring` 2` while the electrode 29 is still held downwardly by the spring 32. As soon as the valve 22 strikes its seat 23, however, the movement ot the valve and the nut 2d stops, and the cage 20 continuing its movement, the flange 26 strikes the nut 2oLL on the stem 27 and quickly opens the. spark gap between the

electrodes

29 and 30. Upon t-he continuation ot the operation, tl e fuel will next be admitted to the other explosion chamber in the same manner. Vhen it is time to again open the valve 22, the rod l5 again descending, first closes the spark 2rap by reason ot the action ot the spring 32, and upon con tinued movement downward, the valve 22 is opened as before.

The lower end ot the chamber ift is provided with a toot piece or plug having iurostanding` lugs 36, which `form a positive `pump cylinder for the purpose ot adjustment or repairs without removing` the cylinder troni the well, the toot-piece 35 o'l each chamber is formed at its lower extremity with a nipple, provided with quarter threes# 33, which may be engaged with corresponding tema-le quarter threads 39 torined in the cover plate which is secured to the upper end ot' the cylinder, preferably by .velf ing. Sui'rounding` the orifice in which the q1 threads 39 are formed, are a pluialit,y of lugs having inclined faces al, which, by the engagement with the outwardly extendingr shoulders 42, `direct the lower threaded end et the valve chamber into proper relation to engage the threads 39.

lt will bc understood that the cylinder 2 is divided by a vertical central partition into two compartments, in the upper ends oli which the tuel introduced, and the ai* plosions take place alternately in the two compartinents. l

The toot-piece is toriiied vwith a recess l-V, which encloses the valve 22 and the spark pluga 29, and the walls ci this recess are preterffibly tapered downwardly to torni a sort or" vortex, whereby the -fuel charge as it is forced under pressure into the ex plosion chamber will be directed across the electrodes, thereby preventing the accumulation ot soot or the like.

order to procure the greatest efficiency and the inaniinum tiow of water, the coinpartments iu the cylinder 2 should be provided with inlet openings ot cons extent. ln the torni shown in Fi;Y`r 2 to o, inclusive, l have shown each compartment provided in its bottom` with three inlet nipples oit comparatively large size and controlled by gravity valves a6 oi' a well known type. The side of each compartment is also provided with three inlet nipples el? oit elbow shape, each being provided at its upper end with a valve seat 43 and gravity valve 9. lt will noted that the lower wall 47a ot cach eiliow terms an abutment or stop tor the corresponding valve 43, while the valve cage t3 is provided with an lao inwardly-turned lip 48a `that toi-ms stop which is ene-aged the toot 49a ot each valve itl The wall ot the cylinder 2 is Jreterabl f )revit d 1with removable )lates Yi i o0 which provide ready access to the valves. The two compartments ot the cvlinder 2 e. :7 provided with large outlet nipples 5l and 52, respectively, which are secured in the cover e0, and extend downwardly to a point near the valves 49, as will bc seen from Figs. 2 and 2. connecting member for directing the streams from the nipples 51 and 52 into the pipe 3, is fori'ued from a swage nipple, the larger end of which is somewhat elongated, as shown at in F ig. 4;, and the upper end tapers at -/l (Fig. 3) to connect with the lower end of the pipe 3.

As soon as thc fuel charge is introduced into the upper end of one of the compartments in the cylinder 2, the valve closes and immediately hereafter the fuel charge is ignited, the expansion of tie ignited gases forcing the water upwardly through one of the nipples, as 51. This L water being discharged through the A. p 54 will also draw a considerable volume of water through the other nipple 52 by a suction action, and will, at the same time, completely scavenge the chainber in which the previous explosion has taken place. Ports 55 may also be provided in thc lower part of the wall of the swage nipple 53, in order to increase the flow of water being delivered. Toward the end of the eXplosion action, a considerable portion of the burned gases'will escape with the stream of water, and preferably 'there is provided a. duct 56 through which the remaining products of combustion may subsequently be exhausted.

At this period of the operation, the other compartment has been filled with water by the suction action above described, and the fuel charge is'next forced under compresA sion into said compartment preparatory to the next explosion. The operation of the compressor 8 and the cam shaft 17 is so timed that the water which is siphoned into the explosion chamber, as it completes the scavenging of the burned gases, meets the incoming fuel charge and increases the compression thereof, whereby a very high degree of compression is obtained at the moment of ignition.

The preferred means for operating the fuel inlet valves and the ignition device through the rod 15, is illustrated in 1.4.-. Each of the pipes 12 and 1.8, where it is connected to the pipe 11 leading from the compressor, is also provided with an er:- tcnsion nipple 57, to which is secured a sleeve 58, a suitable packing` gland 59 being` provided to prevent the escape of the fuel mixture around the rod l5. This rod eX- tends upwardly through the sleeve 58, and provided at .its upper end with a head 30, in which is journaled a roller 61 that coacts with the cam 16 as the shaft 17 is rotated. A suitable compression spring` G2 surrounds the upper end of the rod 15 within the sleeve 58, and maintains the roller 61 at all times in contact with the cam 1.6, the tension of the spring being suitably adjusted means of lock :nuts 63, and ade justable nur.; 6lbeing also provided as a stop at the uoper end of the sleeve ln Figs. 15 and 16, l have shown a modilied arrangement which is in the nature of a single acting pump having a single firing chamber 65. As shown in the drawings, this firing chamber may be attached to the side of the cylinder 2 near 'the upper end, and is provided in its bottom with a large valve 66 controlled by a spring o7 and cov ering the maior portion of the bottom area. The lower electrode 30 of the spark plug is secured to the side wall lof the firing chamber, as by means of a bracket 31a. In this form also, a single inlet 68 is provided in the bottom of the cylinderl and controlled by a spring 69. Upon the explosion taking place in the chamber 65, the water is forced upwardly through the pipe 8, the lower end of which, 51a, terminates near the top of the ,cylinder 2.A

lt is also. to be observed that in the construction shown in Figs. 2 and 3, the water pipes 51 and 52 necessarily terminate at their lower ends at a considerable distance above the lower end of the cylinder 2, in order to allow for the inlet ports l5 and 47. rlhis permits a considerable water hammer in the lowerend of the cylinder, and in heavy work, unless the cylinder is made exceptionally strong, it is liable to burst. Under such conditions, therefore, I prefer to construct the cylinder 2 as shown in Figs. 17, 18, 21 and 22. In this construction, each of the firing chambers is in the form of a cylindrical tube 70, which is connected at its upper end with an intake pipe 71 secured to the lower end of the valve chamber 151.. These 'cylindrical firing chambers are connected at their lower ends to a cylindrical box 72 which is separa-ted diametrically by a partition 73. rllhe water passes from the cylindrical boX 72 upwardly through the respective pipes 7 1l, through the connector or swage nipple 75 into the pipe 3. rlhe box 72 is provided in its bottom with a number of inlet nipples 76 which are controlled by gravity valves 77. The lower ends of the cylindrical chambers 70 and 7e are welded or otherwise secured to the upper wall of the boi; 72. The boi; is strengthened against lateral strain by means of bolts 78, which also provide stops to lignit the upward movements of the valves In this lform of the invention, when the explosion takes place in the upper end of the cylinder 70, it will be seen that the expansive force of the explosion is directly utilized to force the water downwardly in the cylinder 70 and upwardly in the cylinder 74, and I,there is practically no space below the moving current of water where a water hammer could resultv lt .is also preferable in some cases to. provide an exhaust outside of the Water colpe 3, in order to lreep the water free m impurities. Also, since the proper scavenging of the firing chamber, when there is no independent exhaust pipe, depends upon the suction action induced by the explosion in the other firing chamber, it Will found that when the outlet noz- Zle is restricted, as in the case of a fire hose, or Wherever it is desired to expel the. Water with considerable force, the scavenging in such cases may not be complete.

ln Figs. l?, 19 and 20, l have shown an exhaust pipe 79 alon side of the Water column 3, and provideoat its lovver end with a manifold 8O which is connected at each end with valve bei: 8l having a nipple 82 connected with the intake and exhaust passageway Tl. The exhaust is controlled by a valve 83, which is` normally closed by a spring 84, and may be opened at the proper time by means of a lever 85 Which is connected by a rod 86 to a lever 87, mounted above the Well and actuated by a cam 88 on the shaft l?. lWith this structure, the burnt gases will be completely exhausted from the firing chamber under all condi tions of use.

From the foregoing description, it Will be seen that l have provided a pump of the internal combustion type which is operable under all conditions of use to cause a continuous flow of Water., and wherein the poiver is transmitted directly and Without any appreciable loss of energy to the Work to be performed. l have described and illustrated in the drawings What may be considered at present the preferred forms of my invention, and l have described a number of the Ways in Which it may be utilized. lt is to be understood, however, that other .modifications and adaptations may be made Within the scope of the appended claims Without departing from the spirit of the invention.
