O. M. SHOLBERG PUMP COUNTERBALANCING MEANS Original Filed Dec. 2, 1926 Mme/4 o 2d wane/a0 Patented Jan. 1, 1929 UNETED STATES meme OLE M. SHOLBERG, F FEB/GUS FALLS, MINNESOTA.
. PUMP-COUNTERBALANCING MEANS.
Original application filed December 2, 1926, Serial No. 152,222. Divided and this application filed July 25,
This application is a division of my pending'U. S. application Serial No. 152,222, filed December 2, 1926, now Patent No. 1,658,306, issued Februar 7 7, 1928.
The invention has relation primarily to ver tically disposed water pumps which rise from well platforms and are provided with pump rods projecting vertically above the pump bodies. The parent application just referred to, protects a unique form of ack for operating the pump rod and connected parts, and it is the object of the present invention to provide new and improved means for counterbalancing the pump red, the well-contained part-s carried by said rod, and the pump jack, so that the pump may be operated with about half as much power as would be otherwise needed.
vVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.
Fig. 1 is a side elevation illustrating the invention.
Fig. 2 is a fragmentary side elevation at right angles to Fig. 1.
Fig. 3 is a horizontal sectional view on line 33 of Fig. 1.
In the drawing above briefly described, 5 denotes a well platform, 6 has reference to a pump body rising therefrom, and 7 denotes the usual pump rod projecting upwardly from said body. Connected to the upper end of this rod, are two vertical bars 8 whose intermediate or lower portions are slidably mounted in appropriate guise means 9. Pivoted to the lower ends of these bars 8, are a pair of links 10 whose upper ends are connected to a crank 11 on a shaft 12 which may be suitably driven and mounted. All of the parts so far described are more fully explained in the parent application above re ferred to, and the present application is not particularly concerned with them.
A horizontally disposed U-shaped bar 13 is secured at its ends to the lower ends of the Serial No. 208,269.-
The sheave 23 is rotatably supported between a. pair of inverted LI-shaped bars 24 having feet 25 at their lower ends to be secured by lag-screws or the like 26, to the platform 5. The upper lateral ends of these bars are bowed away from each other to some extent as seen in Fig. 3, providing seats for disposition at opposite sides of the pump body 6, said seats being denoted at 27. Transverse bolts 28 pass through the lateral ends of the bars 2d at opposite sides of the pump body 6 and serve to tightly clamp said bars and body together. Thus, the sheave 23 is properly supported and it will be seen that the bars 2 may be quickly and easily attached to the pump and platform. Moreover, when so attached, said bars form efiective means for bracing the pump body, as well as providing for the support of the sheave.
Excellent results are obtainable from. the details disclosed and they are therefore preferably followed. However, within the scope of the invention as claimed, variations may be made.
I claim:
In combination with a pump body, a. pump rod and a pump jack having vertically disposed bars connected with said pump rod, a horizontally disposed U-shaped bar secured to said vertically disposed bars, a cable connected to the intermediate portion of said U- shaped bar, a counterbalancing Weight carried by said Cable, a sheave over which said cable is trained, and means mounting said sheave on said pump body.
In testimony whereof I have hereunto affixed my signature.
, OLE M, SHOLBERG.
