To all whom it may concern:

Be itknown that I, FRIEND A. ALLEN, a citizen of the United States. residing at Granger, in the county of Scotland and State of Missouri, have invented certain new and useful Improvements in Pumping Apparatus, of which the follow-ing is a speciiication, reference being had therein to the accompanying drawing.

This invent-ion relates to that class of pumping apparatus in which water is raised from a well or other deep placeby means of compressed air alternately delivered to a pair-of cylinders submerged in the water in the well.

The invention has for its object to provide an improved apparatus of this kind which will be simple in construction and effective in operation and so constructed and arranged that the operation will be continuous and spasmodic action avoided.

Referring to the accompanying draw- 1ngs:Figure 1 is a view in elevation, partly broken away and in section of a pumping apparatus constructed in accordance with this invention, and shown in operative position in'connection with a well. F1g.'2 1s a plan new of an air engine employed 1n connection with this invention. F1g. 3 1s a detail side vlew, partly in longitudinal section, of a portion of the valve operating mechanism connected with the air engine. Fig. 4 is an enlarged detail view of a portion of the frame of the engine and a portion of a pair of valve operating rods operated by the engine. Fig. 5 is a detail view of a pair of gear wheels operated by the engine. Fig. 6 is a detail view of a pair of rods partly shown in Fig. 4, in cross section, and their connecting links. Fig. 7 is a detail view in cross section of one of said rods shown in Fig. 4. Fig. 8 is a block forming a part of one of the cylinder heads ofthe air engine. Fig. 9 is a block which is secured to the block shown in Fig. 9 and forms therewith one of the cylinder heads of the cut off engine.

and means for conveying the water alternately drawn from said cylinders to the point of supply.

In carrying out the invention, an air. engine is provided mou'nted in a suitable frame Lhaving a cylinder 2, a piston rod 3, a cross head +1, and a crank rod 5 pivoted to the cross head atone end and connected at its other end to the crank shaft 6. The heads of the cylinder 2 are each formed of a pair of rectangular blocks 7 and S secured together in any suitable manner. the blocks 8 having a vertical passage way 9 open at the top and opening at its lower end laterally into a chamber 10. The block 7 is formed with a transverse passage way 11, as shown in Figs. 9 and 14, which opens at one end into the cylinder 2 and at its other end into the chamber 10 in the block 8. The block 7 is formed on one side with a pair of semi-circular projections 12 located one above another and spaced apart so as to provide guides for a valve, the straight edges 13 of the semi-circular projections 12 forming said guides between which is mounted a valve 14 consisting of an oblong rectangular block having project-ing laterally from one side an oblong rectangular block 15 which is located transversely in the passage Way 11,'as shown in Figs. 10 and 11, and is slidable lengthwise therein. Projecting laterally from the projection 15 is a valve stem 16 which projects through a hole 17 in the block 7 and beyond the same. The valve 14 is provided with a transverse opening 18 which, by the movement of the valve 14, is brought into and out of alinement with the passage way 11 thereby opening and closing said passage way. The inner end of the valve stem 16 has mounted thereon a nut 18 which is movable into and out of a socket 19 in the block 7 as a valve 14 is moved backward and forward. The valve stem 16 is provided. at its outer end with a vertical pin 20, as shown in Fig. 3. When the blocks 7 and 8 are secured together, the valve 14 is movable on the guides 13 to open and close the communication of the passage way 11 with the chamber 10 in the block 8. Referring to Figs. 10 and 11, the valve 14 is shown in closed position in Fig. 10, and in open position in Fig. 11 in connection with the opening 11.

The. inlet valves 14 are aiternately opened and closed by means of a reciprocating slide 21 mounted in guides 22, the pins 20 projecting up through slots 23 in the slide 21 and being acted upon by the slotted slide 21 in its reciprocating movement. The slide 21 is pivotally connected at one end to a rod 24, having at its other end an enlarge-1 ment 24' mounted upon the eccentric 25 secured to the crank shaft 6. Connected with the vertical openings 9 in the blocks8 of the heads of the cylinder 2 are'the depending ends 26 of a ipe 27, on which is mounted a three-way ctihpling joint 28 from which leads a pipe 29 connected with a compressed air storage tank 30 which is supplied with compressed air from a compressor not shown.

Connected with the three way coupling joint 28 are pipes 31 and 32 formed of pipe sections coupled together so as to extend a considerable distance to permit the cylinders 33 and 34 connected respectively with the pipes 31 and 32 to be suspended in thewater of a well 35, as shown in Fig.

1. The pipe 29 is provided with a globe valve to regulate the flow of air through the pipes 31 and 32. A globe valveserves as a throttle valve to control the supply 'of air to the cylinder 2. Each of the cylinders 33 and 34 is provided in its bottom with an inlet valve 36 of any suitable well-known construction whereby water may be admitted to the cylinders from the well. Connected with the 'top of the cylinder 34 is a pipe 38- and with the top of the cylinder 33 is a pipe 37, which are for the purpose of permitting the escape of air from the cylinder when necessary.

' Located in the pipe 31 is a valve casing 39 containing a valve and in the pipe 32 is a valve casing 40 containing a valve. The valves in the casings 39 and 40 are connected to a rotary rod 41 so as to alternately open and close the pipes 31 and 32 when said rod is oscillated. The pipe 27 takes only enough air to run the engine, the main part of the air passing alternately through the pipes 31 and 32. Mounted on the rod 41 are tappe'ts 42, located at a right angle to each other as shown in Figs. 1, 4, and 7, and adapted to be alternately struck to oscillate the .rod 41 by means of a pin 43 depending from a horizontal toothed wheel 44 meshing with a toothed wheel 45, as

shown in Fig. 5, the shafts of said toothed wheels being mounted in a support 46, and the shaft of the wheel 45 having at its upper end the toothed wheel 47 which meshes with a worm 48 mounted on thecrank shaft 6. Located onone end of the crank shaft 6 is a balance wheel 49 which may be connected by a band with a suitable driving.

power and on the other end of the crank shaft 6 is a balance wheel 50. Located adjacent to and parallel with the rod 41 is a rotary rod 51 which is connected at one end to a valve in a valve casing mounted on the pipe 37 and at its other end to a valve in the valve casing 53 and mounted on the pipe 38, the valves of said casings operating to alternately open and close by means of the rod 51 which is connected with and operated by the rod 41 by means of a pair of links 54 loosely connected at theirends to rings 55 mounted on the -rods 41 and 51.

'Mounted on each ofthe cylinders 33 and 34 is a vertical pipe 56 for the discharge of water from the cylinder, each of said pipes 56 being provided with a valve 58 at the-upper end of said pipe which is connected by a branch pipe connection 59 with the pipe 60 which leads to a point of discharge as indicated partly by dotted lines. The air discharged from each of the cylinders through the pipes 37 a-n'd'38 when the valve in the casing 52 or 53 is open is conducted to the open air through one of the pipes 61, shown in dotted lines, in Fig. 1.

The operation of the apparatus is as follows :In Fig. 1 the cylinder 34 is shown as having water admitted thereto and the valves in the valve casings 39 and 53 are open and the valves in the valve casings 52 and 40 are closed. By means of this arrangement of the valves, the engine being in action, compressed air is sent through the pipe 31 and drives the water from the cylinder 33 up through the pipe 56 and'through in the casings 39 and 53 and opening the valves in the casings 52 and- 40. By means of this alternative operation of the valves together with the alternative action of the valves of the engine compressed air is alter natively delivered through the pipes 31 and 32, respectively, and water is alternately admitted to the cylinders 33 and 34, discharged therefrom and carried to the source of supply. 7

It is obvious that many minorchanges may be made in the form and construction of this invention without departing from the essential principles thereof. I do not, therefore, desire to confine myself to the exact form herein shown and described but an air engine, of a water receiving chamber with'an inlet valve mounted on the end of each of said branch pipes and'adapted to be suspended within a well, a valve in each of said. branch pipes, an air escape pipe connected with the top' of each of said cylinders, a valve in each of said air escape ipes, a water discharge pipe connected withthe top of each of said cylinders, a rotary rod connected with said valve in the branch pipes, a second rotary rod connected'with each valve in the air escape pipe, a link connection' between said rods, apair of tappets on the first named rod, a toothed gear wheel having a depending pin adapted to successively engage said tappets and alternately operate the same, a second toothed wheel meshing with said toothed wheel, a toothed wheel on the opposite end of the shaft.of

said second toothed wheel, and a worm meshing with said last named toothed wheel,

and mounted on the crank shaft of the en-' gine.

In testimony whereof I hereunto aiiix my signature in presence of two wltnesses.

r FRIEND A. ALLEN.
