Appiication filed June 3, 1908.

To all whom it may concern:

Be it known that I, ROLAND O. BINGHAM, a citizen of the United States, residing at Mount Gilead, in the county of Morrow and State of Ohio, have invented certain new and useful improvements in Pumps, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in pumps for wells, cisterns and the like.

The object of the invention is to provide a pump of this character which may be quickly and easily removed from the well for the pur-' pose of repairing its valves or other reasons, without removing the stand-pipe or other fixtures in the lower portion of the well.

With the above and other objects in View, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional view through my improved pump; and Fig. 2 is a detail horizontal section taken on the plane indicated by the line 2-2 in Fig. 1.

1n the drawings 1 denotes a portion of a well, cistern or the like, and 2 its cover in which my improved ump is mounted. The pump comprises a cy inder 3 which is removably mounted in a casing 4 which has a standpipe 5 depending from its lower end and its upper end suitably connected to the cover 2. As shown, the casing 4 is cylindrical and of slightly greater internal diameter than the pum cylinder 3, and at its upper end is an nnu ar flange 6 to rest upon and to be bolted or otherwise secured to the top of the well cover 2. The lower end of the cylindrical casing 4 is closed by a removable screw cap or head 7 into which the water pipe or standpipe 5 is threaded. Adjacent to the upper end of the casing 4 is a vent aperture or air hole 8 and adjacent to its lower end is a drain hole 9.

The pump 3 which may be of any suitable form and construction is adapted to have its lower end rest upon a gasket 10 arranged in the bottom of the casing 4- and at or adjacent to its upper end is an annular flange l1 adapted to rest upon the flange or top 6 of the casing and to be detachably secured thereto by bolts or similar fastenings 12. As illustrated, the pump 3 has a cylindrical body Specification of Letters Patent.

composed of upper and lower sections having a detachable screw threaded connection 13, the lower section having at its bottom a check valve 14. Another check valve 15 is arranged in the plunger or piston 16 carrying a sucker rod 17, which latter may be actuated by any suitable means. In the pump cylinder 3 may be provided a small drain hole 18.

From the foregoing it will be seen that by removably mounting the body of the pump in the casing 4 which has the stand-pipe depending from its lower end and means at its upper end for supporting it from the cover of the well, the pump may be readily removed so that it may be cleaned, its valves repaired, etc. By mounting the pump in this manner the necessity of removing the stand-pipe or other pipes and connections in the lower portion of the well is obviated and the pump may be more quickly and easily cleaned and repaired.

Having thus described my invention what I claim is:

1. The combination of a casing having an air vent opening adjacent to its top and a drain opening adjacent to its bottom, a stand-pipe depending from said casing, means at the top of the casing for securing the same to a well cover or the like, and a pump cylinder removably arranged in the casing and of less diameter than the latter, said cylinder being formed with a drain opening.

2. The combination with the cover of a well or the like having an opening, of a casing arranged in said opening and provided at its top with an apertured flange 6 to rest upon the cover, the body portion of said casing being cylindrical and having its lower end internally threaded and its side portion formed with the air vent opening 8 and the drain opening 9, a removable screw cap engaged with the threaded lower end of the casing, a stand-pipe depending from said cap, the washer 10 arranged in the casing upon the upper face of said cap, a pump cylinder of less diameter than the casing removably arranged therein and composed of upper and lower detachable sections having a screw threaded engagement with each other, the lower section being adapted to rest upon said washer and containing a check valve and the upper section being formed with the drain Q meme opening 18 and'the 'apertured flange 11 toirest, In testimony whereof I hereunto affix my upon thefiange fi ofthe casing and ltogh'ave signature inuthepresence-of two Witnesses.
