DEEP-WELL rowan PUMP.

T 0 all whom it may concern:

Be it known that 1, ANDREW J. NIcHoLAs, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Deep-Well Power Pumps, of which the following is a specification.

This invention relates to pumps, and particularly to double stroke deep well pumps, and one of the objects is to produce a device of this nature in which the structure may be very compact, requiring comparatively small head room.

Another ob ect is to produce a new and improved form of cross-head whereby the two cross-heads may operate simultaneously in opposite directions and without interference with each other or with the operating members therefor, and whereby the angula-rity between the plane of movement of the cross-head and the axis of the operating links may be minimized.

Another object is to construct a device of this nature so that the mechanism in the well may be quickly and easily removed and without the necessity of moving the base and principal superstructure.

Another object is to provide a new and improved operating mechanism whereby an invention consists of certain novel features of construction and combination and are rangement of parts, the essential: features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation of my im'- proved pump. I

Figure 2 is a side elevation of the same.

Figure 3, is a fragmentary sectional view 7 taken substantially on line 3--3 of Figure 2.

Figure 4 is a detail the upper cross-head,

perspective view of Figure 5 is a similar view of the lower cross-head.

Like characters of reference refer to like parts in all views. Referring to the drawing in detail, 10

indicates the usual T-fitting which is the outlet head for the well, the water being I expelled through the side opening as is well understood in the art. Mounted for movement in the member 10 are the usual tubular and rod plungers'll and 12, the plungers flpot shown) being of the over-lap type whic are well known in the art and which serve the purpose of having a continuous flow of water even at the slowest speed. It is to be borne in mind that it'is desirable that the speed be slow and that the stroke 7 be comparatively long. A closure member 13 is secured to the top of the T 10 in any suitable manner and formsa suitable hearing for the plunger rod or tube 11.

The frame-work of the pump itself comprises a base portion 14 which may be set upon and bolted to any suitable foundation or supporting means, and removably supported side members 15 and 16 which carry at their top a head-frame 17 securing the members 15 and 16 together. The various portions of the .frame may be bolted or otherwise secured. Extending from the head-frame 17 at opposite sides, are brackets 18 which form the upper seats for guide rods 19, the lower ends of which are suitably supported in bosses 20 formed on'the upper face of the member 13.

Slidably mounted upon the rods 19 are the upper and lower cross-heads 21 and 22.

These cross-heads form an important part of the present invention, and will now belde' scribed in detail; Each of the cross-heads is constructed in the form of the letter E and 1s ab e'sleeves 23for sliding engagement with the aforesaid guide rods 19. The sleeves are rods without the necessity of removing the guide rods from the frame. -There-is also .ceive and hold its respective one of theplunger rods 11 or 12. In the case of the upper cross-head pivot studs 25 are secured f I a central member 24 which isadapted to reto the central-member 24; while in the case of the lower cross-head 22 pivot studs 26 are I provided with removable and interchange-- lar attention to the fact that the E-shaped construction of the cross-heads permits the links 29 to extend from the lower cross-head upwardly through the upper cross-head, and

I the lower links 28 to extend from the upper cross-head downwardly through the lower the upper lever 41 are secured to the shaft cross-head without interfering in any way with the operation of an of these parts.

This is clearly illustrated 1n Figure 1.

Mounted in bearings in the frames 15 and 16 and extending transversely therebetween,

are shafts 30 and 31. Mounted upon the shaft 30 is the lower lever beam 32 and similarly mounted upon the upper shaft 31 is cam 33, these parts being duplicates of each-other but reversed-in their position as shown clearly .by the dotted lines 1n Figure 2. Secured to the lower arm of the lever beam 32 and removable therefrom is an extension member 34 which is bifurcated as shown in Figure 1, its arms 35 being connected pivotally' to the lower ends of respective-links 28. A similar extension member 36 is secured to the upper arm of the lever beam 33 and has its arms 37 connected ivotally to the upper ends of respective lin s '29. The reason why the membersj34 and 36 are made separable from the lever beam is .so that they and the mechanism which is directly in the well may be removed Without the necessity of moving the frame or any of the parts hereinafter described and which constitute theoperating mechanism of the device} The device may be driven from any suitable sourceof power, and for the purpose of receiving this power, a-gear 38-is mounted on the end of a shaft 39, said shaft being supported in split bearings 40 mounted on the side frames 15 and 16. i A air of gears I etween' the frames 15. and 16, and mesh with respective gear wheels 42 mounted. onstub shafts +43;

said shafts 43 being gourn'aledin split i liear ings 44 in the side rames of the machine.

The gears 42 are secured to each otherby a crankpin 45 having its op osite ends ex tending through and secure torespective wheels Between the two wheels 42 there are mounted on the crank in 45 a pair of cross-head blocks-46 and 4 ,the dross-head provided for it in the upper lever beam 7 33 and block 47 along a way 49 in beam 32,

and in consequence as the wheels 42 rotate,

the pin 45 by moving the cross-head blocks 46 and 47 along the ways 48 and 49 will cause an oscillation of the lever beams 32 and 33 and a consequent upward and downward movement of the links and cross-heads connected thereto, and of the members 11 and 12. Y

It will be noted that with this form of operating mechanism when one of the crossheads is drawn u wardly the other is moved downwardly and cross-heads move on the guide rods 19 toward and from each other.

-While I have described what I deem to be the most desirable embodiment of'my invention, 'I do not limit myself to the specific details of construction of material, nor to anything less than the wholeof my invention as defined in the appended claims.
