' well-pumping power-machine or other device used in the transmission of power, wherein a reciprocating motion is required to be distributed to several distant points located in" dillerent directions, by means of rods, wires, or cables leading from the power-house, where the oilwell-pumping power-machine or similar device is stationed and connected to the pumping apparatus at the several wells, of which the following a specification. My invention relates to that class of ccntrics, which are used in connection with the Oll well minnno )ower machines, so
called, now used so extei'isively on oil prop erties: where it is desirable to pump a number of oil wells from the power generated by one engine; and the same is applica lc to similar machinos or devices, used in the transmission of power, where a reciprocating motion required to be distributed as set forth above.
The object of my invention is to overcome and minimize the loss of power through the excess of friction due to the attrition of parts; together with the unnecessary strain upon the pumping power machine, or other device, caused by the jerking motion of the connecting rods, where the old style eccentric wheel and ringare in use. I refer to that type of eccentric wheel having an extension in the outer rim near the bottom, extending outward from the face, which serves as a support, on which the ring rests, the inner face of said ring being fittcd to the outer face of the eccentric wheel above said support.
In my in'iaroved eccentric, I accomplish the objects set forth, by using in comb nation: an eccentric wheel having a groove in the outer face of the rim, so shaped, that it conforms to the contour of adjustable wheel bearings, for which the said groove serves as a runway and support; so that an odd number of the wheel liicarings, three or more, I prefer five, being placed in position, properly assembled and adjusted in conjunction with the outer ring, and balanced by the proper arrangement of swivels or other device, used in connecting the rods, wires or cables, leading tothe several Wells; the revolving of the eccentric wheel keyed to the vertical shaft of the pumping power machine, working in conjunction with the wheel bearings and the outer ring, causes a steady reciprocating motion, on each con necting rod in turn, of sufficient forward, baclm'ard. and lateral swing, to insure" the proper stroke required to pump each Well, or
other device connected thereto.
In the drawings hereto attached and made part hereof: Figure l, is a top section view showing the general appearance of my in1- proved occentricwith the several parts assembled in position. 2, is a cross sectionview on the line 1, 2, in Fig. 1, showing the method of'assembling the several parts of each adjustable bearing in the elliptical shaped supports of the outer ring, the groove in which the wheel bearings rotate, the arrangement of a suitable oiling device, and the relative position of the vertical shaft of the power machine. the component parts of each of the adjust.- able wheel bearings. Fig. ehshows theshapc of the adjusting slots in the top and bottom portions of the outer ring, which serve as elliptical pimped SUPPUItS for each of the adjustable bkzlill'lg'S. Fig. a sectional view ofthe outer face of my ii'u n-oved eccentric, showing-the grooved runway in the face of eccentric wheel; togc her with a por-' tion of the outer ring which shows one menu her of the wheel bearings assembled in position.
Similar letters refer to similar parts throughout the several views.
The eccentric wheel A, having hole B, and key seat in the hub fitted to receive the large shaft of the pumping power machine see Fig. l, and Fig. 9, and having a groove in the outer face C; so shaped, that it conforms to the contour of, and serves as a run way for the wheel bearings S, which revolve around the small shafts I, having a shoulder L, neaithe bottom, which rests upon the inner face of the bottom portions of the elliptical shaped supports F, (see Fig. 3, and Fig. in the outer ring D, and a rectangular extension M, through which the hole 0, (see Fig. 2,) is drilled near the end, to receive a cotter pin P, designed to hold the Fig. shows
