Specification of Letters Patent.

n Patented Nov. 12, `190'?.

Application filed March 20. 1906. Serial No. 307.124.

To all whom 'it may concern:

Be it known that I, THOMAS ELwooD MOON, a citizen of the United States, residing at Sabina, in the county of Clinton and State of Ohio, have invented certain new and useful Improvements in Pumps; and I do hereby 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 use the same.

The main object of this invention is to provide a very efficient, serviceable and practicable pump of simple and cheap construction, for use in eisterns, tanks and shallow wells, and for other relatively light service,

'whichobject `is attained by the novel construction and features of improvement hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, which form a part 0f this specication, Figure l is a perspective view of a pump embodying my invention, an intermediate portion of the pump-barrel being broken away and the parts being brought together for shortening the illustration. Fig. 2 is a central longitudinal section. Fig. 3 is a detail perspective view showing a fragment of the pump-barrel, this portion of the pump-barrel having a lateral opening for exhaust oi water through the spoutor nozzle. Fig. 4 is a detail sectional view oi a fragment ofthe pump-barrel and piston, representing the piston on the down stroke. Fig. 5 is a section on line 5-'-5 of Fig. `2, looking upward, showing the piston in bottom plan view. Fig. 6 is a detailp'erspective view ofthe piston proper. Fig. 7 is a transverse section through the flap-valve at the lower end of the pumpbarrel. Fig. 8 is a sectional view showing a joint between contiguous sections o a long pump.

The pump-barrel A is desirably made of light metal tubing, preferably galvanized sheet-metal. It may consist of one pipe section or tube, or in the case oi a comparatively klong pump-barrel it may comprise a number of pipe sections or tubes joined together by iuserting the end of one tube in the adjacent end of another and soldering them, as shown in Fig. 8, with a band or short sleeve a slipped over and fitting closely around the joint thus made, such band or sleeve a having its endsy soldered to the contiguous pipe sections.

Near the upper end of the pump-barrel, or at a suitable `distance from the top, the nozzle or spout B is attached, the same being also desirably of light tubing or sheet-metal, and having its inner end fitted to the lateral opening in the wall of the pump-barrel and soldered aroundithe same. Said opening inthe pumpbarrel is formed by making a cross-cut in the wall of the pump-barrel and then bending the quarters b thereof ,outwardly and apart, thereby providing a support for the inner end oi the spout, which fits over the quarters b ormetal projections and may be soldered, riveted or otherwise attached thereto.

At the top of the pump-barrel is a cap C preferably of wood or other suitable material, which is attached to or in the upper end of the barrel, and is centrally bored to form a guide for the piston-rod D, the latter being shown provided with a'haudle E for operating the pump.

The piston F is attached to the piston-rod D between the collar or shoulder d thereon and a spider or support G, which latter is fastened on the lower end of the rod by the nut g, awashcr d being shown arranged between said spider and the bottom side of the piston. Said piston F comprises a disk f of thin flexible material, such as leather, to which is riveted or fastened two half-parts or semi-circular pieces f of relatively thicker or heavier or stiffer material, or if desired semi-'circular pieces composed of a number oi layers or thicknesses; whereby the piston acts as a double clack or butterfly-valve, comprising two semi-circular lobos or leavcs hinged together at the middle. As the piston descends, these loaves iold upward toward or against the piston-rod, allowing the water in the pumpbarrel to pass above the piston; and when the piston is drawn upward, said leaves fall or drop back upon the support or spider G and come in Contact with the walls of the pump-barrel, forming a packing, and permitting the piston to raise the water and force it out through the spout or nozzle Bf "he semi-circular pieces f may be Composed of leather, rubber, or any suitable material, but preferably some material which is impervious. to or not affected by water, such as rubber, in Order to preserve the iorm of the piston and avoid shrinkage or stretching, to which leather is ordinarily liable, and thereby preventing the piston from becoming either too tight or too loose.

At the lower end of the pump-barrel is a short conoidal or outwardly flaring section or part H, which is attached to the lower extremity of the tubular barrel B, as shown in Fig. 2, in the same manner as already described with reference to the joint of contiguous pipe sections. This short section or tapered bottom piece H, which has a closed bottom, is preferably made of stronger, heavier or stiffer metal than the tube of the pump-barrel, thereby strengthening the lower end of the pump where the pressure is greatest, and allowing the cutting of the lateral water inlet ports or orifices h without unduly weakening this lower part of the pump, and also permitting these orifices h to be larger and fewer in number. There are preferably two or more of such orifices h arranged vertically one above another in the side oi the bottom piece I-I. In service these ports or orifices are below the water line, and allow a free supply of water to the pump-barrel.

A valve .I controls the inlet ports h. This valve consists of an oblong convex piece or strip of metal, covyered on its Convex side with leather, rubber or other attached thereto. The valve is arranged to cover the ports or orifices h and is shown suspended by a flexible metal strap j/ riveted or fastened to the upper end of the valve and to the wall of the pump-barrel, so that the valve hangs down over the ports and swings freely inward and outward7 thus opening and closing the ports with the up and down movement of the piston, without remaining in close fitting contact. This prevents the lodging or holding of any particles or sub# stances that would usually be held by close-fitting valves7 causing them to leak and requiring the pump to be primed before starting a iiow.

This pump being of the single-acting valved reciprocating piston type, its operation is obvious7 it being understood that as the piston F descends the valve J closes, while the folding or doubling up of the piston allows the water to pass above the same; and when the piston ascends, 'lifting up the water and discharging it through the nozzle7 thc suction -created thereby opens the valve .T and allows the water to follow the piston; maintaining a full and free flow of water throughout the length of the pump-barrel. The opening 'L' below the piston also allows a back-flow of the water that is drawn up into the pump-barrel, so that when the pump is idle the water will gradually settle back to the water line, thereby liberating any gases7 preventing the formation of odor and noxious constituents in the water, and preventing the pump from freezing.

A support or brace K is provided for the pump-barrel at a suitable distance above the cover of the cistern, well or tank. This support as shown comprises a yoke, whose legs are provided with feet k for attachment to the cisternA cover; the .yoke being formed with a semicircular or curved part c, towhich is bolted a similar part k2, the pump-barrel being clamped between the part 7c and k2 at a suitable height above the cistern cover. This form of brace is an improved feature to a pump of this character wherein the pump-barrel is made of light metal.

It will be understood that various changes may be made in the specific form and details of constructiony of the pump, and the invention may be embodied in modiiied forms.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:-

l. The combination of a cistern or shallow-well pump, of a sheet-metal pump-barrel having a cap at its upper end and a lateral opening near said end having surrounding portions of metal cut out in forming said opening projecting laterally and adapted for the attachment thereto of a discharge spout and also a frusto-conical portion at its lower end provided with inlet openings at one side thereof, together with an inwardly-opening valve controlling said inlet openings and a piston-rod extending through an opening in said cap and carrying an upwardly-opening valve, substantially as described.

2. In a cistern or shallow-Weel pump a pump-barrel composed of sheet-metal tubing having a frusto-conical portion at its lower end with closed bottom and valve-controlled inlet openings at one side, said pump-barrel near its upper end having a series of projections integral therewith for attaching a discharge spout thereto, said projections being formed by bending sections of the metal cut out in forming a discharge opening communicating with the spout, substantially as described.

In testimony whereof I aix my signature, in presence ofl two witnesses.

THOMAS ELWOOD MOON.
