DEEP-WELL PUMP.
SPECIFICATION forming part of Letters Patent No. 421,247, dated February 11, 1890.
Application filed August 1, 1889.
' had therein to the accompanying drawings, in
- ism.
which-- Figure 1 represents a side elevation of the pump-operating mechanism; Fig. 2, a transverse sectional view on the line H H of Fig. 1; Fig. 3, a view, partly in section and partly in side elevation, of the pump complete; Fig. 4, a sectional view of the pump-cylinder with its pistons, and Fig. 5 a View showing a slight modification of the pump-operating mechan- In the accompanying drawings, a designates the base-plate of the pump, which plate is suitably secured to the platform of the well. Erect-ed upon the base-plate is a frame composed of the four upright bars 7) and the platform 0, the ends of the said bars being secured to the base-plate and platform by means of nuts I), tapped on the bars. J ournaled in suitable bearings upon the platform 0 are two grooved pulleys d, and between the supporting-rods 1), near the base-plate and in line with the upper pulleys, are two similar pulleys (1. Connecting the respective pairs of pulleys are endless cables or chains e, the lnner portlons of the cables passing through apertures c in the platform 0. suitably bolted upon the center of the platform 0, between the two pulleys d, is a vertical cylinder f, provided with suitable stuffing-boxes in its heads for the passage of the piston or pump rod 9, this pistoinrod being provided with a suitable piston g Within the cylinder. Attached to the upper end of the piston-rod is a cross head or arm h, secured to the ends of which are two depending con= necting rods t, these rods being guided in their movements by the ears g", cast upon the cylinder heads. These rods are further guided by being passed through the holes 0 in the platform. The lower ends of the rods 2' are attached by means of clamps to the inner portions of the respective endless cables 6, whereby the said cables are moved in unison. Connecting the outer portions of the Mounted and Serial No. 319,454. (No model.)
cables is a crossbar j, which is provided with apertures jfor the passage of the inner portions of the cables and the reciprocatory rods 2'. This cross-head j has secured to its center a tubular pump-rod k, which passes down through a stufiing-box in the base-plate, and is provided at its lower end with a valved piston or plunger 7a, which works in the pump-cylinder Z.
The pump-cylinder is suitably secured within the well-tube, and is provided with the usual check-valve l at its lower end.
The piston -rod 9 passes down centrally through the tubular pump-rod and its piston, and is provided with a valved plunger m at its lower end. That portion of the rod g which passes through and works in the plunger 7a is formed rectangular in cross-section to prevent the plungers and their rods turning independently of each other, whereby accidental unscrewing of the sections of the pump-rods is prevented and obviated.
In the device shown in Fig. 5 I show that only one of the endless cables may be employed without departing from the invention.
The cylinder f is provided with any suitable valve-chest and valve mechanism whereby to admit the motive fluid, which may be steam, air, water, or other fluid.
When motion is imparted to the piston in the cylinder f, the pumprod g and its plunger will be reciprocated in a corresponding direction, while the tubular rod and its plunger will, through the medium. of the rods c'and endless cables, be simultaneously moved in the reverse direction. By thus operating the plungers of the pump in opposite directions a steady and continuous supply of water will be obtained.
By the arrangement of devices-shown and described the pistons will be operated with a minimum of friction and wear and jar.
The invention is designed particularly for deep-well pumping; and its essential feature consists in operating the oppositely-movable pistons simultaneously with a vertical steamcylinder mounted directly over the well and connected directly with the main piston of the pump.
Having thus fully described my invention, what I claim is The combination of a frame, a cylinder f,
loeing' provided with a valved plunger, a
pump-cylinder for this piston to Work in, a tubular pump-rod 7c, surrounding the rod 9 and provided at its lower end with a valved plunger and at its upper end with an arm j,
IO a downwardly-extending rod or rods t', connected tothe upper end of rod g, and an endless cable or cables connecting the rod i to the arm of the rod g, substantially as described.
In testimony whereof I affix my signature in presence of tWo Witnesses.
