Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may: concern:

Be it known that we, FRED M. OI-IENO- WETH and ALnIs J. MILLER, citizens of the United States, residing at Lynn, in the county of Randolph and State of lndiana, have invented certain new and useful Improvements in Pumps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This inventionrelates t pumps, and more especially to that class thereof known as lift and force; and the object of the same is to produce a pump whose working parts are all below the freezing point and located within a metal shell which avoids the necessity for a large pit, and yet are all readily removable from the'shell by first removing its cover. These objects we accomplish by the construction hereinafter more fully described and claimed, and as shown in the drawings wherein- Figure 1 is a side View of the pump, the shell indicated in dotted lines; Fig. 2 is a central vertical longitudinal section on an enlarged scale; Fig. 3 is a horizontal section taken on. line 33 of Fig. 2; Fig. 4 is a similar. view on line 4-4 of Fig. 2; Fig. 5 isa plan view of the base; Fig. 6 is a detail side elevation of the pump casing.

In the drawings the numeral 1 designates the shell which is screwed at its lower end at 2 into a base 3, the latter having a bore surrounded by a shoulder 4 into which fits the upper end of the well casing 5, and set screws 6 holding these parts together. The base is cored out as at 7 with an L-shaped passage in whose. upper end extends a nipple 8 and in whose lower end is screwed the underground discharge pipe 9 through which water lifted by the pump may be forced to any desired point beneath the freezing line. Diametrically opposite said cored: passage 7 the upper face of the base 3 is provided with a socket 10 for a purpose which will appear. This entire base is by preference one piece of rather heavy casting, and its bore'll is by preference of the same internal diameter as the bore 12 of the well casing 5.

The shell is closed by a preferably flat cover 15 which forms the base for the pump proper as best seen in Fig. 1, and this cover has. an internal flange, 16 adapted to fit into the open upper end of the shell and a surrounding flange 17 through which pass hook bolts 18 having nuts 19 above the flange 17 and having their hooked lower ends engaging holes 14 in the sides of the shell 1.

lVithin the shell is removably inserted a circular casting 20 which is hollow so as to provide an internal chamber 21, its bottom having a lug 22 adapted to engage said socket 10 so that it may be properly disposed upon the base 3, and opposite said lug this casting 20 may carry said nipple 8, gaskets 23 surrounding the nipple and lug, and a wrench-hold 24 depending from the center of the bottom and adapted to pass into the bore 11 of the base 3, itself being tubular so that the inlet pipe 25 may be screwed into it as shown in Fig. 2. Directly above this pipe and in axial alinement therewith the pump barrel 26 rises through the top of this hollow casting 20, and within it are located the leathers 27 on the pump rod 28 which rises loosely through the cover 15 and is manipulated by a handle 29 in the-ordinary manner, its lower end being connected by a coupling 30 with a pump rod extension 31 which may lead downward through the inlet pipe 25 to a piston 32 as indicated in Fig. 2. By the mechanism thus far described, manipulation of the handle 21 causes this piston 32 to raise the water through the inlet pipe 25to the chamber 21, while the leathers 27 force it out through the nipple 8 and underground discharge pipe 9.

A feature of our invention consists in providing an air chamber which consists of a tube opening at its lower end as at 41 into the top of the chamber 21 and extending thence upwardly and loosely through the cover 15 and through a boss 42 on the top of the same wherein it is held by a set screw 43; and making this tubular air chamber at its upper end into the shape of a fork 4-4 wherein at 45 is pivotally mounted the handle 29. This tubular air chamber therefore serves not only the functionof an air chamber, but also as a means for lifting the hollow casting 20 out of the shell 1 when desired, and. as a fulcrum for the handle 29. Through another boss 52 in the cover 15 extends the discharge pipe which leads to a point above ground, its lower end being connected by a bushing 51 with the top of the hollow casting 20. The lower end of this bushing and the upper end of the nipple 8 serve as valve seats for a valve, which latter consists of two disks 53 separated by a washer 54L and clamped by nuts 55 upon a valve rod 56 which extends upward through the discharge pipe and may be reached at the upper end in any convenient manner.

When this rod 56 is raised the uppermost disk 53 closes against the lower end of the bushing 51, and the water'within the chamber 21 is forced out the underground discharge pipe 9; and it will be clear that when the valve rod is depressed the lower disk 53 is closed upon the valve seat formed by the upper end of the nipple 8, and the water within the chamber 1 is forced up through the overground discharge pipe 50. Thus we provide means, manipulated from a point above the ground and within reach of the operator, for controlling the outlet of the water raised by this pump.

When it is desired to gain access to the interior of the shell 1, the hooks at the lower ends of the bolts 18 are disengaged from the holes 1 1 in the shell, the nuts 19 first being loosened, and the entire cover 15 raised. With it comes the tubular air chamber 40 and the overground discharge pipe 50; and obviously the pump rod 28 with its leathers and valve may be drawn upward, or by grasping the pump barrel 26 the entire casting 20 may be lifted out of'place. When the parts are restored and the hooks reengaged with the holes 14:, they resume the position shown in Fig. 2 and all working parts are below the ground level and therefore the liability of freezing is decreased.

Various changes in the details may be made without departing from the spirit of our invention, and it is clear that the sizes, proportions, and materials of parts are not essential. The operation of pumps of this character is so well understood that we will not amplify here.

What is claimed as new is:
