To all whom it may concern:

Be it known that I JOHN Hnronnzcs, a subject ofthe King oi Great Britain, residing at Capel House, 62 New Broad street, in the city of London, England, have invent ed certain new and useful Improvements in and Relating to Direct-Acting Pumping Machinery, of which the following is a specification.

This invention is designed to improve the construction of pumps for raising and forcing fluids, such as water, petroleum and other similar liquids of a non-corrosive nature, and of the kind known as direct acting pumps, actuated by compressed air, steam or other elastic fluid, or it may be driven by water.

According to the invention an im roved construction of valve and valve mec anism which serve tov control simultaneously the fluid to be driven and the motive fluid, are employed to direct said fluids into an improved arrangement of channels or passages adapted to serve alternately as admission or exhaust or delivery ways to and from the cylinders for the motive and the driven fluids res ectively. A common source of supply of lubricant is provided and the general construction and arrangement of the pump is such that the whole of the reciprd eating and other moving parts are totally inclose In the drawings:Figure 1 shows a front view of the pump partly in section. Fig. 2 shows a side elevation of Fig. 1 taken from the right hand side. Fig. 3 shows a correspendin side elevation taken from the left hand side of Fig. 1. Fig. 4 shows a section taken about the line A, A, Fig. 1. Fig. 5 shows a section taken centrall and at right angles to Fig. 1, in order the tter to show the valve actuating parts. Fig. 6 shows another sectional view of the central parts of Fig. 1 taken on line parallel to but in rear of the line of section adopted in that figure. F i is an upper side view of the parts seen in 1g. 2. Fig. 8 is an upper side view of the top of Fig. 1. Fig. 9 is a section taken through the middle of the respective passa es, a, b, 0. Fig. 10 is a similar section taken through the passages 15, 18, 20. Fig. 11 is a cross section of these passages 15, 18, 20, taken on the line B,-B, Fig. 5. Fig. 12 is a similar view on the line C, C, Fig. 5.

According to this invention the valve comprises two truncated conical members p, g,

each provided with oppositely disposed spincllcs n to which a lever i is keyed, and whereby angular movement is imparted to the valve; said leverbeing actuated by mechanism to be hereinafter described.

The member p of the valve is formed with a part-circumferential port 1 and with an axial port p, and the member g is formed with a part-circumferential port m and with a U-shaped internal port 422,.

21, 21, are packing rings and 22, 23, are screw caps whereby the said portions p and g are retained in position.

. f is a fluid tight chamber wherein is situated valve-o eratin mechanism and which is filled with lubricant supplied by a ipe 24 from a suitable source (not shown). rom said chamber 7 ducts or channels 25, 25, convey the lubricant to spaces 26, 26, (Fig. 1) whence the lubricant exudes on to the piston rings and the cylinder walls, the piston rod a passing through said chamber also conveys lubricantdurnig its reciprocation to the glands through which it P3559?- cl, k, are pistons connected to a common piston rod c and adapted to reciprocate in cylinders c, g, respectively. Communicating with said cylinders and co-acting with the ports in said valve members p and are a series of assages or channels for t e conveyance 0? respectively. y p

The fluid employed as the motive agent enters under; pressure at the pipe a and passes therethrough to the part-circumferential port 1 in the valve 1) and enters the passage 1) whence it is delivered throu h the opening 2 into the upper cylinder 0. this cylinder 0 th" re reciprocates the piston (I mounted upon the rod e. Wi11f2h passes through glands 3, 4, in the cyhr 1ers c and g respectively and through t e intermediate motive fluid an. of driven fluid lubricant chamber f. Caps 5 close the ends of the respective cylinders c and g. Mounted on said rod e and reciprocating 1n the cylinder 9 is the piston h winch, during the downward movement of the piston d, descends and draws fluid to be forced along the passage 20 and around the part-circum- The pressure of the motive fluid at the upper side of the piston d causes said piston to descend, any fluid which may be contained below said piston d being exhausted through the opening 17, passage 0 and axial port the valve member at this time occupying the position indicated in Figs. 2 and 9.

The valve operating mechanism comprises a stud 6 on the piston rod e which during the reciprocation of the latter contacts with the extremity 7 of the lever i moving said lever :ngularly in a downward direction and lowering the cylinder 8, articulated to said extremity 7. The movement of the cylinder 8 compresses a coiled spring 9 contained therein against the end of a secondary member 10 carried by trunnions 11 mounted in bearings in the extremity 12 of the lever k,- and cylinder 8 slidin telescopically within the secondary member 10. The stud 6 having. moved the lever 2'- to about a horizontal position said stud comes into contact with the end 13 of the lever is and moves said lever A: augularly about its pivotal axis 14, lowering the end 13 and raising the end 12. Directly the horizontal position of theparts is attained and passed the compressed spring 9 expands and instantaneously imparts angular movement to the valve; the arts then assuming the positions indicated by dotted lines in Fig. 5. This angular movement imparted to the valve reverses the positions of the ports from those shown in Figs. 4, 5, 9 and 10.

causes the lower face of the iston d to receive the pressure of the motive fluid which enters throu h an aperture 17 from the pipe 0 controlled by the part-circumferential I port 1 of the valve 1;; motive fluid being supplied to said ipe o from the main supply pipe a. As t e piston d rises, the fluid above itwhich reviously served to efl'ect its downward stro re, is exhausted from the upper portion of the cylinder 0 throu h the opening 2, passa b and axial port p from which port the aid is discharged from the apparatus. Similarly the simultaneous reversal of the portion of the valve diverts the flow of the forced fluid, and the upper face of the piston it forces the fluid out from the cylinder 9 through the passage 15 and the U-sha interna port m of said valve g into t e delivery pipe 19. At the 85 same time fluid to be orced is drawn throu the inlet 16 (which lpreviously serv as a delivery port) from t e pipe 18 which through the part-c rcumferential-port m is in communication with the mam intake The replacement of thevalve to the initial position is eflected by the stud 28 during the return stroke of the piston rod e.

The intake end of the main sup ly ipe 20 for the'fiuid to be forced may he ti tted The reversal of the portion p of the valve ports to direct said fluid towa with any convenient trainer cf bulbous or other form.
