PEEP-WELL PUMP.
SPECIFICATION forming part of Letters Patent No. 323,805, dated August 4, 1885.
(No model.)
To all whom it may concern:
Be it known that we, LEWIs GRIscoM and JOHN P. G-nIsooM, citizens of the United States, and residents of Pottsville, Schuylkill county, Pennsylvania, have invented cer tain Improvements in Deep-Well Pumps, of which the following is a specification.
The object of our invention is to counteract or partially counteract the lateral strains to which the sucker-rods of deep-well pumps are subjected (luring the downward stroke of the bucket, and to thereby enable us to operate the buckets of this class of pumps at a much greater speed than usual. This object we attain in the manner which we will now proceed to describe, reference being had to the accompanying drawings, in which- Figure 1 is a view, partly in section, a deep-well pump made according to our invention; Fig. 2, a sectional plan on the line 1 2; Fig. 3, a sectional plan on theline 3 4; Fig. 4, a sectional plan on the line 5 6, and Fig. 5 an enlarged view of part of Fig. 1.
The pump or barrel Ais screwed at its upper end into a short pipe, G, and into the latter is screwed the longest section, E, of the well-tube, the barrel having at its lower end the socket D for the foot-valve.
The above-mentioned parts are found in ordinary deep-well pumps, and therefore. need not be minutely described. The valved pumpbucket H, moreover, is similar to those in common use in connection with deep -well pumps. Instead of securing the rod, however, directly to the bucket, we attach to the lower end of the rod a weight or heavy iron bar, I, as illustrated in Figs. 1 and 5, the lower end of the lowest section, J, of the rod being screwed into the upper end. of the weight or bar, while the lower end of the'latter may be connected to the bucket by a universal joint.
The joint we prefer to use is the ball-andsocket joint illustrated in Fig. 5, a spherical enlargement, a, being formed on the upper end of a stud, K, and this enlargement being confined within a socket formed by the end I) of the bar I, and the nut d screwed onto the same.
In pumps of the class to which our invention relates, the pump-rods, generally termed sucker-rods, are usually made mainly of hard wood, with a view to lightness. While these rods, whether made partly of wood or entirely of iron, are capable of resisting the tensile strain to which they are subjected, they are so deficient in lateral stiffness that the speed at which the plunger reciprocates must be restricted, otherwise they are liable to buckle or be bent against the side of the well -tube during the downstroke, owing to the resistance caused by the packing of the bucket and by the water-into which the bucket is forced.
The heavy bar I, interposed between the lowest section of thesuckerrod and the bucket, is designed to obviate this difficulty, the weight of this bar being such that it will overcome the above mentioned resistance during the downward movement of the bucket and sucker-rod, thereby relievingthe latter from the objectionable lateral strains to which the rod is subjected, and permitting the bucket. to be reciprocated at a greater speed than would be possible in the absence of the weight.
WVe are aware of the patent of Mayhew, N 0. 52,364, January 30, 1866, for oil-pump; but in that pump no sucker-rod was used, the bucket being carried by a rope, and a weight alone being relied on to produce the downward stroke of the bucket.
In our apparatus the downward as well as the upward stroke is produced by the sucker-rod, and the weighted bar simply serves to keep the sucker-rod straight and prevent it from buckling.
In the Mayhew device, gravity being entirely 'relied on for the downward stroke, the piston speed is necessarily extremely slow, much more slow,in fact,than in a pump provided with a sucker-rod without any weight, whereas with our improvement the pump can be run at more than twice the pis- In testimony whereof we have signed our ton speed of a pump having the sucker-rod names to this specification in the presence of without the weighted bar. two subscribing witnesses.
Ve claim as our invention 5 The combination of the tubing, bucket, LINVIS GRISGOM.
and sucker-rod of a deep-well pump, with JOHN P. G'RISOOM.
