'1 Claim. (01. 103-178) The present invention relates to new and useful improvements in sludge pumps, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is particularly adapted for cleaning underround tanks in rural locations, which are without sewerage facilities.
Another very important object of the invention is to provide a sludge pump of the aforementioned character comprising a valved reciprocating piston of a novel construction and arrangement.
Other objects of the invention are to provide a sludge pump of the character described which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight, and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in side elevation of a sludge pump constructed in accordance with the present invention.
Figure 2 is a vertical sectional view, taken substantially on the line 22 of Figure 1.
Figure 3 is a vertical sectional View, taken at right angles to Figure 2.
Figure 4 is a view in horizontal section, taken substantially on the line 4-4 of Figure 1.
Figure 5 is a bottom plan view of the reciprocating piston.
Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a vertical cylinder I of suitable dimensions and material. Projecting from the upper portion of the cylinder I is a discharge spout or trough 2. Mounted on the lower end of the cylinder I is a substantially cup-shaped closure 3. The closure 3 includes a flat marginal flange 4 having formed integrally with its periphery an upstanding, internally threaded ring 5 which is screwed on the lower end portion of the cylinder I. An elevating tube 6 depends from the closure 3 and communicates therewith. A ball check valve I is operable in the substantially cup-shaped closure 3 and engageable in the upper end of the tube 6 for preventing return flow of the fluid after it enters the cylinder I.
A valved piston 8 is operable in the cylinder I. The piston 8 includes a metallic ring 9 having formed integrally therewith a vertically extending yoke Ill. Secured by screws II (see Fig. 5) beneath the ring is a flat, metallic ring I2. The ring I2 has formed therein an integral, substantially dome-shaped seat I3 which projects upwardly into the ring 9. The piston 8 further includes a cup packing I4 which encircles the ring 9 and which travels on the walls of the cylinder I. The packing M is provided, on its lower end portion, with an internal flange I 5 which is secured between the rings 9 and I2 and which abuts the seat I3, the securing screws II passing through said flange. The flange 4 of the closure 3 provides a shoulder on which gasket It in the form of a ring rests. The ring I2 of the piston 8 is engageable with the gasket I 5 when said piston is in lowered position, as seen in Figure 2 of the drawings.
Rising from the yoke I0 is a pair of spaced posts I7. A crosshead I8 is mounted on the upper ends of the posts I'I. Mounted on the posts I! at an intermediate point is a guide I9 in the form of a metallic bar. Extending slidably through the guide I9 and the upper portion of the yoke III is a stem 26. A valve 2| is mounted on the lower endof the stem 28. The valve 2! is engageable on the seat I3 for closing the opening or port 22 therein for preventing return flow of the fluid.
A suitable bracket 23 is mounted on the upper portion of the cylinder I at a point diametrically opposite the discharge spout 2. Journaled at an intermediate point on the bracket 23 is a lever 24 constituting the pump handle. Pivotally connected to one end portion of the lever 24 is a rod 25 which rises from the crosshead I8.
It is thought that the operation of the pump will be readily apparent from a consideration of the foregoing. Briefly, on the upstroke of the piston 8, which is actuated by the lever 24, the valve 2! is in closed position and the check valve 1 is raised to open position as the fluid and other matter are drawn upwardly into the cylinder I through the tube 6. On the downstroke of the piston 8, the valve I closes and the valve 2! is raised to open position by the fluid, et cetera, passing upwardly through the opening or port 22. Thus, this fluid is forced through the opening 22 above the piston 8. As this operation is continued the fluid rises in the cylinder I and flows therefrom through the discharge spout 2.
It is believed that the many advantages of a sludge pump constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:
A sludge pump comprising a cylinder, a valve controlled tube communicating with said cylinder, a piston operable in the cylinder, said piston including a metallic ring, another ring secured beneath the first-named ring, a substantially dome-shaped seat, having a fluid passage therein, integral with the inner periphery of the second-named ring and rising therefrom into the first-named ring, a packing encircling the first-named ring and including an internal flange on its lower end engaged between the rings and abutting the seat, a yoke rising from the first-named ring, spaced posts rising from said yoke, a crosshead mounted on the upper ends of the posts, a guide extending between the posts at an intermediate point, a stem slidable in the yoke and the guide, a valve on the stem engageable with the seat for closing the opening, a rod rising from the crosshead, and an operating lever connected to said rod.
