f `frolaiun.v (01.103-153) `This invention relates to'a novel ways and means, characterized essentiallyby an automatically functioning chemical pump, for forcing chemicals or other liquids into'pressureor nonpressure pipe-lines, tanks and `analogous receiving containers. Briefly, the'structural arrangement adopted for my purposes is characterized by a single double-action pump cylinder and piston unit which operates on both the up and down strokes of the piston and is, therefore, devised so that the pressure internally is equalized and so that by subjecting the piston rod tothe action of a weight applicable thereto, Jthe piston will 'force the chemical or other liquid into the pressure line or other container at the desired proportionate rate.
More specically, the overall structure is characterized by the aforementioned single type double-acting pump means or unit, this having valved connection at one point with a chemical supply reservoir or tank, having valved pipe connection at another point with the main fluid conductingvconduit or pipe-line, and there being a third valved auxiliary pipe-line from the conduit to the top of the pump cylinder to achieve the desired equalizing of theifluid in said pump cylinder on opposite sides of the piston head.
Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings, wherein like numerals are employed to designate like4 parts or elements throughout the same:
Figure 1 is an elevational view of the complete assemblage, that is, the chemical supply reservoir or tank, main conduit, double-acting pumpand valved piping connections between the respective parts.
Figure 2 is an enlarged vertical section on the plane of the line 2-2 ofvFigure 1. i
Figure 3 is a horizontal section on the line 3-3 of Figure 2.
Figure 4 is a fragmentary detail view showing the removable lead ball weight on the upper end struction of the pump 8, attention is directed to Figure 2. It comprises a'cylinder 9 secured to a base plate IU which is boltedV or otherwise secured to the platform. This is provided with inlet and discharge ports I I and I2 properly proportioned and threaded. At the topv is an annular collar I3 forming a ledge for securing the disk-like top plate I4 in place.V The plate I4 is bolted to the ange I3 as at I5 and is provided with a screw-threaded port I6. The plate also carries an appropriate stufng box or gland I1 for the reciprocating piston rod I8. The head of the piston I9 is provided with upper and lower packing cups 20 and 2|, these being in frictional fluid-tight contact with the inner surface of the cylinder. As brought out in Figure l the intermediate part of the piston rod is shouldered as at 22 and forms a reduced extension 23 to accommodate a ball, that is, a lead weight 24 of ball or other form. In practice, it is possible to use a series of washer-like or disk weights which canbe stacked on the shoulder 22 and held in place by the reduced stem 23.
A chemical delivery pipe-line 25 is connected with the bottom of the chemical tank 1 and is, in turn, connected with the threaded hole II in the bottom of the pump cylinder. This is pro- ,Vided with a cut-off valve 26 of appropriate construction. An auxiliary feeder pipe-line '21 connects with the other hole I2 and is, in turn, connected at its opposite end, as at 28 with the main conduit or pressure pipe-line 6. Here again we have a hand-regulated valve 29 of appropriate construction in the pipe-line 21. Atk a longitu dinally spaced point there is an equalizing auxiliary pipe-line 30 which has its upper delivery end attached to the top of the pump cylinder above the piston as at the point I6. Close to the pump is a drain-cock 3I. The numeral 32 designates a cut-oi valve.
The operation is as follows: With the piston or plunger down in the pump cylinder, the valve 29 in the feeder line 21, and the valve 32 in the equalizing pipe-line 30 are both closed. The valve 26 in the line 25 is then opened to permit ow of chemical from the supply tank 1 to the pump cylinder 9. The pump piston is raised by hand and the cylinder of the pump iilled with the chemical. AThe valve 2G is then closed and the two valves in the auxiliary pipe-lines, that is, the valves 26 and 32 are then opened to equalize the pressure above and below the piston, that is, inI the upper and lower chambers above and below the piston in the cylinder 9. The metal ball or weight 24 is then placed in position on the upper end of the piston rod and this is of sufficient Weight to overcome the friction of the piston head and packing cups on the wall of the cylinder. The valve 29 is then adjusted to regulate the flow of the fluid, that is, the chemical into the pressure line and the unit is in operation for continued automatic operation. The pipe-line 30 from the pressure line to the upper intake of the pump cylinder, through valve 32, connects to the rear on the main pressure line suflciently distant so that the supply line from the pump to the pressure line carries the chemical into thel pressure line and on with the flow of the fluid being treated. To rell, the valves are set again as above noted and the drain-cock 3l is opened 'to permit the untreated fluid in the top chamber to drain out as said pump cylinder is reiilled. The drain-cock is then closed and the operation is repeated.
It -is thought that persons skilled in the artto which the invention relates willbe able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.
Minor changes in the'shape, size and arrangement of details coming Wlthinthe eld of invention claimed may be resorted to in actual practice, if desired.
Having described the is claimed as new is:
In a. structure of the class described, a piunping cylinder for delivering iluid under pressure, said cylinder embodying a base `with an outstanding marginal flange adapted for anchorage on a relatively fixed support, the bottom of said cylinder having a 'chemical intake and supply port, a. valved chemical supply pipe connected to said port and adapted for connection with a chemical supply tank, said bottom being further provided with a chemical discharge port, a valved pipe connected to said chemical discharge port, the major portion of said cylinder being imperforate, a closing plate for the top of the cylinder having a stung box and a port, a third valved pipe, this connected with the last-named port, a. piston comprising a head slidable in said cylinder invention, what and including upper and lower packing cups, said head serving to divide the cylinder into upper and lower chambers in respect Ato said top and bottom ports, said piston also including a reciprocatory rod extending upwardly through and beyond said stuffing box, and a detachable ball weight havingr a socket mounted on the upper end of said piston rod.
