PUMPlNG-RIGGING FORvQlL-WELLS.

SPECIFICATION forming part of Letters Patent No. 592,655, dated October 26, 1897. Application Eea February 24,1897. seria No. 624,799. (No model.)

To all whom it may concern.- v

Be it known that I, J OHN N. MAHER, a citizen of the United States," residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Pumping-Riggings for Oil-Wells; and I do hereby declare the following to bel a full, clear, and exactv description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in pumping-rigs for use in oil-Wells, Artesian wellsJ and the like; and it consists in certain novel features hereinafter described and claimed.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views. e

Figure l represents a plan view of `my improved pumping-rig. Fig. 2 represents a section along the line 2 2 of Fig. 1. Fig. 3 represents a plan View of a modified form of pumping-rig; and Fig. 4 represents a section along the line 4 4 of Fig.` 3, the connectingrod being omitted.

Referring particularly to Figs. I and 2, A represents the bed-plate on which the apparatus is mounted, which is provided with the pedestal B,provided with iianges b,seoured by means of bolts C to'the bed-plate A. This flanged pedestal B is perforated, as at bo, to loosely inclose the axle G. The space between the axle G and the inner sides of the pedestal B is filled with Babbitt metal B2, whereby the said axle G is held in rigid engagement. Surrounding the said axle are two grooved bearing-rings D and E, with interposed balls F. The lower bearing-ring D is secured to or rests on the bearing-plate, while the upper bearing-ring E is secured to or bears against the hub H' of the crown-wheel H. This hub H is flanged, as at h, and to the flanged portion the eccentricsv K and K0 are secured. These ecoentrics have outwardly-projecting flan ges k lying in a horizontal plane and adapted to support the rings M, which are perforated, as at m0, and serve as eccentricstraps. To any one of these perforations m0 the connecting-rods P or P' may be attached, as by means of the pin p. These eccentrics K and K are held together by the central pin N with its nut n and by theV bolts h', which pass through both eccentrics and engage in the flange h of the hub H. The crown-wheel H is driven by means of the pinion Q on the shaft q, which shaft is driven by the pulley Q' from any convenient source of power. It will be noted that the rings M, which serve as eccentric-straps, are made in one piece and are slipped over the top of the eccentric, where they are supported upon the horizontal flanges 7c, projecting beyond the face of the eccentric.

In the form of device shown in Figs. 3 and 4 a somewhat modified form of j bed-plate A. is shown, and the crown-wheel, otherwise constructed substantially as shown in Figs. l and 2, is provided with a crank-pin H0, engaging the end of the connecting-rod P', which drives the'rotary drums S, mounted on the pivot-pin T and led as by a plurality of ropes U or U to the points where the power is applied. By means of the arrangement shown in Figs. 3 and 4 a reciprocating motion is imparted to the d rums S. The preferred form of construction of these drums has been fully described in my application entitled Pumping-rigging for oil-wells, filed November 2.7, 1896, and serially numbered 613,578, and will therefore not be further described herein.

It will b e obvious that various modifications might be made in the herein-described apparatus whichcould be used without departing from the spirit of my invention.

I claim, and desire to secure by Letters Patent of the United States, is4

In a pumping-rigging, the combination with a bed-plate, of a flanged pedestal rigidly secured thereto, a vertical axle rigidly mounted in said pedestal, a crown-wheel revolubly mounted on said axle above said pedestal provided with a hub having horizontal eXtensions at its upper and lower ends,` bearing rings and balls interposed between said pedestal and said hub, superimposed eccentrics Having thus described my invention, what y rigidly secured directly to each other and to ally connected to said perforated rings, subthe hub of the crown-Wheel, said eccontrics stantially as described. 1o being so arranged with relation to the axle In testimony whereof I aflix my signature as to equalize the strain upon the latter and in presence of two Witnesses.

5 being also provided with horizontal {ianges JOHN N. MAIIER.
