PUMP 1 Application filed March 2, 1926. Serial No. 91 ,740.

My inventionrelates to pumps. It has for its object to provide animproved pump, and more particularly 'an' improved pump of a type adapted to oil field work, as,

tor example, the pumping of mud fiuid or high pressure oil line pumping. A further *object of my invention is to provide a pum ta-ined,'is so arranged as to be economically manufactured and to reduce the cost of upkeep, replacement of broken parts, including the cylinders, being made possible with a minimum of difiiculty andexpense. A still ,further object of my invention is to provide an improved construction for a so-called water or pumping end of a duplex pump having the above characteristics and enabling a highly efiicient, yet simple and rugged double acting duplex pump construction to be produced. These and other objects and advantages of my construction will, however, hereinafter more fully appear.

In the accompanying drawings I have shown, for purposes of illustration, one form which my invention may assume in practice.

In these drawings,-

In this illustrative construction; I have shown my invention embodied in a duplex steam driven pump of a" generally familiar type including a usual steam end '1 having suitable valve mechanism operated through valve gear 2, which is in turn connected to-a part on each of the usual rods 3 of the usual pistons operating in a well known manner in both the steam and water cylinders, this socalled steam end also including, herein, a-

usual frame 4 supported on a foot, 5 and being connected at one end to an improved water end 6, hereinafter more. specifically described. Inasmuch as the steam end per se does not enter into this invention, and this steam end may be of any suitable construction or, in

fact, may be replaced by any suitable or de P sired type of ower drive, the same need not be more speci cally described.

. In my improved construction of pump mechanism per se, i. e. the'so-called water end, it will be noted that the same is herein su ported on an improved suction member f, herein performing the dual function of base and suction member and herein having a centrally located inlet or-suction 8 (Fig. 5); As shown, this suction inlet is, as preferable,

longitudinally disposed and connected at the bottom of the member 7. It also hereinlias embodied therein large branching suction passages 9 and- 10 leading off laterally or transversely in opposite directionsfrom 8 and having large, suitably upwardly curved end passages leading to the suction valves,

cylinders, etc., hereinafter described. More particularly, it will be noted that this member 7 has supporting feet 11 on its opposite ends and is provided with suitable flanges 12 and 13 surrounding the up )erends of the passages 9, 10 and connected y suitable bolts to the body of the pump hereinafter described, and that this member 7, which herein forms the suction inlet means, is so disposed relative to the water end that these suction inlet means form the underlying support for the whole of the latter.

- Referring more particularly to the struc-- ture supported on the suction member 7 it will be noted that this comprises what may v be called right and left cylinder sections 15 and 16, each of which is complete in itself and adapted to cooperate with one of the pump istons 17, and each of which carries a cylinder 18 and a complete setof suction and discharge valves, hereinafter described. It will also be'noted that these partsare so arranged that the passages 9 and 10 lead up at points outside the cylinders 18 (Fig. 5)

and are disposed in supporting position benected, as by screws, with the adjacent end of the frame 4 of the steam end, which thus serves with the underlying suction means to tie together the two sections 15 and 16, while said underlying suction means supports both the front end of the member 4 and the twov sections 15 and 16 and thus combines the functions of a suction supply, a support, and

a connecting member. Referring more par-,

ticularly to the sections 15 and 16, it will also be noted that each carries a pair of suction valves, generally indicated at 19, and a pair of discharge valves, generally indicated at 20, these two sets of valves being disposed at different levels and laterally offset, with the suction valves outside the discharge valves and at a lower level and with a suction valve and a discharge valve at each end of each cylinder, as shown in Fig. 1.

' In my improved construction, I have also connected these two sections 15 and 16 by a discharge manifold having transversely disposed branching pipes 21 extending downward andconnected to the sections 15, 16 at points between the discharge valves 20 on each of the latter. Thus, it will be observed, not only are the sections 15 and 16 held together by their connection to the underlying suction and to the end of the steam on frame 4, but also by the discharge manifold 21, all in such manner as to produce a very rigid construction. Further, it will be evident that, should it be desired to remove either of the sections 15 and 16 for replacement, as when breakage takes place, either one of these sections may be readily removed as a unit and replaced whenever desired without replacing the other. Here attention is also directed to the fact that the pipes 21 of the discharge lead to a common outlet 22 having therein a usual strainer and communicating with a usual chamber 23.

Referring more particularly to the suction mechanism, it will be noted that the suction passages 9 and 10 in the suction 7 each communicate with a large upper longitudinally extending passage 24 on the outer side of one of the sections 15, 16. These passages 24 herein branch longitudinally in opposite directions from the upper ends of each of the passages 9 and 10, andherein also are provided at their opposite extremities with suitably curved portions leading to upstanding passage portions 25. At the upper ends of these portions 25 are carried the suction valve mechanisms 19. Herein, itwill be noted that these valve mechanisms 19 include a usual cover and spring and a reciprocable ported valve 26, the construction being such that the valve may be removable from'the top. It will be understood, however, that any suitable type of valve other than that shown may be used if desired. Moreover, in my present construction the valve 26 of each valve 7 mechanism 19 operates in a suitable annular opening 27 (Fig. 5) in a septum or deck 28 in each of the portions 25 heretofore de scribed, there preferably being one opening 27 ineach portion 25 and one valve 26 controlling the same. Also, it will be noted that a relatively large inner passage 29 is provided above each valve opening 27, which extends laterally across and above each cylinder 18, this passage 29 communicating with the adjacent end of its cylinder through an enlarged downward extension 30.

Referring to the cylinders 18 to which the suction is thus delivered, Fig. 4, it should also be noted that a suitable cylinder closure 32 is held in position on the outside end of each cylinder by usual threaded connections 33, one of which herein extends into a stud 34 crossing the chamber 29, and that these members 32 also carry threaded connections 35, funcrigidly connected by screw connections 41,

which are herein similar to the connections 33, while the member 38 is suitably connected to the end plate 37 by usual removable connections 42 enabling the packing to be re- .newed as necessary. Also, at each end of the cylinder suitable removable plugs 43 are provided, while each of the members 32 and 40 may also be connected to the cylinder by as many supplemental screws as may be necessar 'l he discharge connections to which the discharge is delivered from the cylinders are herein connected directly above the ends of the cylindefs 18 .and utilize the same passages 30, heretofore described, the discharge valves 44 of the discharge valve mechanisms 20 herein being located above'thc inner end of each hereinbcfore mentioned, and are adapted to valve.

discharge valve shown in Fig.

function therewith in the usual manner, the 5, for example, being closed when the suction valve is open. Herein, these discharge valves 44 are also carried in and accessible from the top of upstanding passage means 45 generally corresponding to the portions 25. Moreover, they also operate generally similarly through a second septum or deck 46 above the level of the suction septum or deck 28, and each functions through a single opening 47. It will also be.

noted that each of these valves has above'the same, in the portion 45, a chamber 48, and that the two longitudinally spaced chambers 48 on each section 15, 16 are connected by a longitudinal chamber '49, herein integral with the sections 15, 16,'so that it may receive the discharge from either valve 44; a pipe 21 opening 50 in the top of each of these cham bers49 so that eiich discharge valve is thereby, when functioning, directly connected to the discharge. In the operation of my improved mechanism, it will be evident that as the pistonlrods 3 of the pump pistons 17 are reciprocate d in the usual manner in the cylinders 18, the suction valves 26 and discharge valves 44 also function in the manner usual to double acting duplex pumps. Referring more particularly to the supply connections, it will be observed that the suction 7 will then function through its inlet 8 to receive the fluid to be pumped and supply it laterally and upward through the passages 9 and 10 and into the passages 24 and 25. Thus, the liquid is caused to pass not only below the suction valves 26, but directly to them through a minimum-of passages and also through passages of such size, and length as to minimize the friction and accordingly enable the pump cylinders to fill very completely.

bcfnoted that due to the delivery 0 the suction through its outlets 9 and 10 at points midway between the ends of the longitudinal supply passages 24, the distance through which the fluid must pass to reach the suction valves 20 is not only shortened, but the passages are made identical for each suction Further, the friction isthus also made the same for the flow of each valve.

' Attention is also directed to the fact that, due

to the large area of the passages 29 between the valves 26 and the cylinders 18, friction here is also minimized, there being no restriction calculated to increase the friction at this point. Thus, a uniform and positive distribution of fluid by the suction valves is' insured without eddy 'currentsand with a resultant increased filling of the cylinders and consequent increase in inner ends of these same More particularl it will efficiency. Moreover,

the dischar e nectcd to the by the adjacent or passages 29 and the passages 30, in such manner as to minimize the necessary passage length between the cylinders and the discharge valves and there-' by further reduce the friction.. It will also be noted that the discharge valves are so cylinders valves are also directly conlocated that the liquid passing through each discharge valve passes directly therefrom into the passageway 49 and therethrough to the discharge22, the several discharge pas-v sages herein also being of equal length for each discharge valve, as in the case of the suction passages. Moreover, it will be noted that the discharge from each discharge valve passes to the discharge without the discharge from one valve in any way interfering or coming near the other discharge valve, thereby further minimizing friction by eliminating any interference of one valve with the action of any of the others. of the discharge being connected to a suitable tribution of liquid to each valve in the suc-'. 7

tion and in the discharge, and consequently increase the cylinder filling function of the suction and the discharge function of the dis-' charge mechanism in such'manner as to increase the efliciency of the pump. It will further be noted that while these advantages are obtained, the'structui'e obtained is further improved in such manner as to be exceedingly simple, rugged and inexpensive, involving neither such excessively large and expensive main castin s as have heretofore been generally considered necessary in oil field work, 1101' the necessity for providing supporting means in the form of frames or supportsother' than provided b the suction inlet-means and the steam on supporting means at oppo-' I I Moreover, it, is a permlts of ready but further enables remaybe modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
