SPECIFICATION forming part of Letters Patent No. 777,924, dated December 20, 1904-.
I Application filed Ianuary 26,1904. Serial No. 190,672.
To all whom it may concern.-
Be it known that I, SAMUEL SEARS, a citizen of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented a new and useful Pump, of which the following is a specification.
This invention relates generally to pumps, and more particularly to that class thereof known as lift-pumps, and the object of the invention is to provide a simple and inexpensive construction of pump-cylinder of such construction that after once being put in operation the said cylinder will be perpetually primed.
Another object of the invention is to construct the cylinder in such a manner that the piston or plunger can be removed at any time without disturbing the valve and one in which the valve can be removed at any time without disturbing the piston or plunger; and a still further object is to provide a cylinder which shall have an air-chamber in connection therewith, and thereby greatly facilitate the lifting of the water; and a still further object is to provide a cylinder formed of one piece, thereby greatly reducing the cost and at the same time preventing leakage or other derangement or damage to the pump.
With these various objects in view the in-- vention consists in the details of construction hereinafter fully described, and pointed out in the claims.
In the drawings forming part of this specification, Figure l is a perspective view of a pump-cylinder constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a horizontal sectional view on the lineB 3 of Fig. 2.
In constructing apump-cylinder in accordance with my invention I cast the same in a single piece, said cylinder comprising three tubular members A, B, and O, the member O being arranged between the members A and B and of a greater diameter, as most clearly shown in Fig. 3. The tubular members A and B connect with each other at their lower ends, as most clearly shown in Fig. 2, and at the bottom of the cylinder is an opening D, into which screws the pipe E, which extends down into the well. The tubular portion A is closed at the upper end by means of a screwat its upper end by means of a screw-plug B,
and the cap C screws into the upper end of the central tubular portion C, said cap having an opening into which screws the pipe F and through which works the sucker-rod G, carrying the piston or plunger H at its lower end, said piston or plunger snugly fitting the central portion O, which virtually constitutes the working barrel of the pump. The tubular section A, which is the suction portion of the pump, is divided into two vertical compartments by means of a partition I,-which partition extends nearly to the upper end of the member A, and between this partition and the outer side of the member A is arranged a valve K, which normally rests upon the seat K. An opening L is produced at the lower end of the central portion O at the side adjacent the tubular member A, and through which communication is established between the member A and O, and through which water enters. The tubular member B serves as an air-chamber, the air collecting in the upper portion thereof and serving to aid in drawing the water into the working barrel of the pump. In operation the water passes upwardly through the pipe E, through the opening D, and Hp tlllOUgll the outer portion of the tubular member A, lifting the valve K and passing downwardly upon the other side of the partition I through the opening L. The piston or plunger operates exactly the same as the ordinary piston or plunger or sucker now in common use.
As before stated, the air passes upwardly to the upper end of the tubular member B,
and thereby serves to prevent the formation of a vacuum and also aids in lifting the water through the opposite leg or tubular member It is obvious that a pump constructed as herein shown and described will be perpetually primed, as the water after once passing the valve has no possible means of escaping back into the well. It will thus be seen that by removing the cap O the piston or plunger can be removed without disturbing the valve K, and also that by removing the cap A the valve can be removed without disturbing the piston or plunger, thus enabling the pump to be quickly and easily repaired at any time desired.
By having the air-chamber at the upper end of the tubular member or leg B a longer column of water can be supported than if said chamber were not employed, and if it is desired to support an unusually long column of water the cap B can be removed, a pipe attached to the upper end of the tubular member, and the length of said pipe will of course govern the length of the column of water which will be supported.
It will thus be seen that I provide an exceedingly simple, eificient, and inexpensive construction of pump-cylinder, which will fully carry out all the objects hereinbefore mentioned.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A pump-cylinder comprising a central cylindrical portion, and tubular portions arranged upon opposite sides of the central cylindrical portion, and having free communication with each other at their lower ends and with the suctionpipe, one of said tubular portions being subdivided longitudinally into two compartments, one of said compartments having a valve at its upper end and the other an opening at the lower end which communicates with the lower end of the central cylindrical portion, as set forth.
2. A pump-cylinder comprising a central cylindrical portion and the tubular portions arranged upon opposite sides of the central cylindrical portion, said tubular portions communicating at their lower ends with each other and with a suction-pipe, one of said tubular portions being divided vertically into two compartments, one of which compartments has a valve at its upper end and the other compartment an opening at its lower end which communicates with the lower end of the central cylindrical portion, the screw-plugs for closing the upper ends of the tubular portions and the cap for closing the upper end of the central cylindrical portion asset forth.
3. A pump comprising suction and discharge pipes, plunger and plunger-rod in combination with a pump-cylinder comprising a central cylindrical portion and the tubular portions arranged on opposite sides of the cen tral cylindrical portion and communicating with each other at their lower ends and also with the suction-pipe, a vertical'partition dividing one of the tubular portions into two compartments, a valve arranged at the upper end of one of the compartments, the opposite compartment having an opening which communicates with the lower end of the central cylindrical portion, screw-plugs for closing the upper ends of the tubular portions and the cap-piece for closing the upper end of the central cylindrical portion, the dischargepipe being connected to said cap-piece, as set forth.
