Fla wanton W. H. RAYNER.



Patented 001.12.1909.





To allwhom it may concern Be it known that I, IVILLIAM H. RAYNER,

a citizen of the United States, residing at Springfield, in the county of' Clark and State of Ohio, have invented certain new and useful Im rovements in Power-Pumps, of which the fbllowing is a specification.

My invention relates to improvements in power pumps,- and particularly to power pumps of the vertical type.

The object of-my invention is to provide in a pump ofthis kind means for permitting the plunger rod, valves and cylinder to be readily removed from the well without.

' may be readily removed therefrom as before stated.

My invention censists in the constructions and combinations of parts hereinafter de scribedand set forth in the claims.

In the accompanying drawings Figure 1 is a perspective view of a device to which my invention has been applied; Fi 2 is a. perspective view of a portion of t esame in detail; .Fig. 3 is a detail view of the detachable connect'on inthe plunger rod; Fig. 4 is a sectional'view of the same; Fig. 5 is a detail of the hinge connection for the power head 'frame.

Like parts are represented by similar characters of reference in the severalviews.

The main operating parts of the power pump for which I havedevised my invention are of a well known type;- In the said drawings, it represents a main frame, the particular form of frame which] I have shown in the drawings being of'the open type, although the improvement may be applied toa device of this character. in which" Specification of Letters Patent.

- Application filed January 16, 1908.

' which base, a,

it being ny particular object well Patented Oct. 12, 1909.

. Serial No. 411,040.

ported near the center of the frame instead of the extreme upper partthereof. This frame is supported upon the base, a, in the manner hereinafter more fully described,- rests and is secured to the usual top platform of the well. Also secured to the base and extending into the well is the usual cylinderor barrel, 7f, which iiicloses the plunger rod, 0, and valves in the usual way. This plunger rod, 0, extends up through the T-connection, 7), located on the base and to which the discharge pipe is connected, and is also extended upwardly through a suitable bearing in the frame, (1, and is secured at its upper end to a cross head, (Z, slidingly mounted on guide-rods, (7, which project upwardly from the frame, and derives reciprocatin movement from the driving pulley, (Z t rough the medium of the pinions, (1", gears, (Z and pitman con nections, (Z all of these parts being supported by the frame in the usual manner.

The main driving shaft, d to which the driving pulley is connected is supported in suitable bearings (not shown) on the main frame, a, and the outer end of this shaft. is also supported in the bearing, (1", located on the standard,d The standard, (Z is per-- manently connected to its base or support .and has'a detachable part, d", to which the bearing proper, (Z is swiveled by set-screws,

tZ one only of which is shown; it being understood that the part, (Z will be formed preferably in the nature of a yoke, with a set-screw on each side of the bearing proper, (P, to permit the bearing to be self-alining. The removable portion, (Z fits in arecess or pocket in the standard and is connected thereto by a bolt, (i so as to be readily removable therefrom.

The frame, a, and the various operating parts supported by it are, as before stated, known as the power working head of the device. In order that this head maybe read ily'removed out of the way at any time when it is desired totake out from the well the plunger and valves or the cylinder, I have so mounted and secured this head to the base to permit it to be readily detached and swung back out of the way without disturbingthe arrangement of any of the operating parts on the head. At one end of the frame adjacent to the base I provide a hinge, preferably in the form of a hinge-bolt, e, which passes through lugs, e e, on the rear legs of roaer d as shown Q v ceases the frame and through registering lugs, e

extending up from the base. Each of the. legs of the frame is provided with a foot, a adapted to receive'a bolt to connect thesame to the base. The plunger rod is further, con-.

' structed in two parts the adjacent ends of which are screw threaded and connected tov gether by a nut, or coupling, f. The upper nut.

' base, the p unger rod disconnected, the part,

d, detached from the standard, 03, and the head thrown back about its hinged connection. The parts of the plunger rod may be disconnected either by having the coupling formed'with right and leftthreads or by unl'o'osening the nut, 0 and turning the part, of the rod 0, with a pipe wrench or other tool -untilit isdisconnected from the coupling.

When theplunger rod is thus disconnected the lower part of the rod will drop by gravgwit h the stuffing-box in the upper end of the "cyllnder I or. T-connection, so that this rod .ity into the cylinder for a limited distance,

say until the nut, f, which may have been left on the lower part of the rod, contacts will not interfere in-any Way with the tilting {of the frame but will permit .said frame to readily'clear it.

. means of the detachable b'earingde-. scr1bed'forthe outer end of the main driving shaft, I amenabled to provide means for' firmly'supporting the driving shaft at either endwhich will not interfere with the tilting operation of the head. In this type of ma chine it'is desirable that the parts-be so arranged that the standard, after once being properly secured tothe ground support or floor, can be maintained there and yet permit the remdvable part cari'ying the bearing to be quickly detached and the head tilted.

Having thus described my invention, I

claim I i I 1. In a working head for pumps, the following instrumentalities'. a base having one member of a hinge and having a head with inlet and outlet openings, a piston-rod working through the head and having a coupling,

frame having atits lower end the other hinge member, whereby the frame and base are hingedly connected near the ground, and having driven gears mounted thereon near one side and below the upper end, and a driving shaft and its pinions' mounted .on the opposite side of the frame, each pair of these gears and pinions, respectively, intermeshing, and ocross thead guides carried atthe upper end of the frame, a cross-head on the guides, pitmen' connecting the gears and the cross-head, and an actuating rod oper ated by the cross-head and detachably connected by the coupling to the piston rod.

2. In a working head for pumps, the'combination, with a base having inlet and dis charge openings, a pump rod formed in two parts together with means for detachably securing said parts together, a crosshead attached to and detachable from said pump rod, guide rods on which said cross-head is mounted, a frame for said guide-rods mounted on said base, said frame being hinged to said base and having means for detachably securing it thereto, means for actuating said cross-head comprising a driving shaft and its pulley extending beyond said frame, a

permanently attached support independent of said frame, and a detachable bearing for the outer end of said shaft located on said support.

In testimony whereof, I have hereunto set my hand this 10th day of January, 1908.
