SPECIFICATION forming part of Letters Patent No. 673,789, dated May 7, 1901.
Application led August 17, 1900. serial No. 27,166. (No model.)
To all whom t 11m/y concern;
Be lt known that I, HIRAM O. STOUEFER, a citizen of the United States, residing at Mineralridge, in the county of Trumbull and State of Ohio, have invented certain new and useful Im provements in Pumps, of which the following is a specilcation.
'lhe improvement which forms the subjectmatter of this application is directed to a construction whereby in a liftpump opposing pistons are actuated without separate pumprod connections for the separate pistons. For this purposeI employ in combination the device known as the lazy-tongs, a piston connected to each end thereof in alinement, a fixed connection of the lazy-tongs with the pump-cylinder mediately between the pislons, and a single pump-rod whereby the opposing pistons are caused to have equal stroke to produce a continuous flow in the discharge ot' the water, and so far as I know and can find I am the iirst to employ the lazy-tongs as a connection for opposing pistonsto obtain suoli continuous flow with a single pump-rod.
The accompanying drawings illustrate my improvement, in Which- Figure l is a vertical section of a pump-cylinder with opposing pistons, their lazy-tongs connection, and the single pump-rod, the pistons appearing` as being controlled in the positions of moving away from a fixed mediate point of the lazy-tongs. Fig. 2 is a like View, the pistons being seen as in the limit of their movement toward each other. Fig. 3 shows enlarged a vertical section taken at right angles to Fig. 1 to illustrate the construction by which the links of the lazy-tongs are braced against tendency to buckle at the fixed point of greatest strain and from which both pistons are actuated; and Fig. 4 is a transverse section of the pump, taken through the bracing means for the lazy-tongs. f
It will be understood that the pump is submerged and has suitable pump-rod operative connect-ions. The opposing pistons l l are each provided with a valve 2, arranged to open upward, and to each piston the lazytongs has a pivotal connection 3, while the lazy-tongs itself has a fixed pivotal connection by a diameter-bolt 4, n utted at the Walls of the cylinder. This fixed point has such relation to the length of the lazy-tongs as to cause the lengthening' and contracting movements thereof to give equal strokes to the pistons by one pump-rod 5, which is preferably rigidly connected to the upper piston by the yoke 6. The lazy-tongs is pivoted at its terminal links to the pistons, and in alinement with these pivots and medialely of its length the lazy-tongs is pivotally connected to the pump-cylinder hy the diameter-bolt 4, from which both pistons have their Inovenients from the single pump-rod. It is by this mediate cylinder connection that I am enabled to employ the opposing pistons with the lazy-tongs and with a single pump-rod to produce a continuous-flowing discharge aad to give each piston a stroke governed by the length of the lazy-tongs. Obviously it' the upper piston were dispensed with, the lazytongs having the lower piston only and having a fixed connection at the top of the pumpcylinder, such construction would give only an intermittent lifting action upon the Water. As the strain of both pistons is equally upon the fixed pivot-bolt of the lazy-tongs, I provide a webbed brace 7, which stands inward from the cylinder-walls, as in Figs. 3 and 4, so as to abut against the links and support them against buckling. This wcbbed brace I prefer to make bya screw-section, to which the pump-cylinder sections are screwed, so that the webs 7 7 stand inward against the fixed links 8 8, on which the lazy-tongs is extended and closed. For this purpose I prefer to make the side links 8 8 bowed, so as to stand out on each side of the link. I also prefer to `form the cylinder-web part with sleevebosses 14 14, Fig. 4, through which the pivotpin of the lazy-tongs passes and gives the important advantage of a long bearing to the pin on each side of the lazy-tongs, which greatly increases the durability ot' the pin and also forms a better sealed joint for the pin in the cylinder-Walls.
A foot-valve 9 is suitably secured at the lower end of the pump-cylinder to hold the water therein when the lower piston is on its descent; but inasmuch as the pump is preferably submerged it is obvious that the footvalve may be dispensed with.
The single p ump-rod gives an easy and long ICO movement to the pi'stons,keeping the cylinder always full of water, while the single holt 4 forms the Xed point from which the lower piston has its upward-and-downward .movement and the upper piston has its upward# and-downward movement, these movements of both pistons being produced yby a single pump-rod.
In Fig. l the arrows 10 indicate the direction of movement of the pistons'in the ascent of the pump-rod and the arrows 11 indicate the upward flow of the water into the pnmp-cyl inder between Athe pistons, while the arrows 12 show the flow of the water from the cylinder above the upper pistons.
In Fig. 2 the arrows 13 show the directions in which the pistons will move on the ascent of the pump-rod.
While I prefer to connect the lazy-tongs med'iately of its length to the pump-cylinder to give equal strokes to the pistons, yet such connection mav be made that will give 'unequal strokes to the pistons.
Obviously the pump-rod may be connected directly to the lazy-tongs at a point between the pistons, by which construction a short stroke of the pump-rod would give a com paratively long stroke to the pistons.
I claim- 1. In a pnmpand in combination with a cylinder, a lazy-'tongs pivoted mediately of its length to the walls of the cylinder, a
valved piston pivotally connected to each end of the lazy-tongs, a pump-rod rigidly connected to the upperpiston, and. means whereby the lazy-tongs is braced and supported at their pivotal connection upon the cylinderwalls.
2. In a pulnp and in combination with a cylinder, a lazy-tongs pivotally connected me- `diately of its length to the pump-cylinder, a
piston pivotally connected t0 each end of the lazy-tongs and having an upward-opening valve, and a pump-rod connected to the npper piston, and webbed braces on the inner walls of the pump-cylinder for bracing the lazy-tongs at its cylinder connection.
3. In a pump and in combination with a cylinder, a lazy-tongs pivoted mediately of its length to the walls of the cylinder, a valved piston pivotally connected to each end of the lazy-tongs, a pump-rod rigidly connected to the upper piston, and a webbed brace on the inner walls of the cylinder, each brace abutting the mediate links of the lazy-tongs and formed with a sleeve-boss hearing for the pin.
In testimony whereof I aix my signature in presence of two witnesses.
