PUMPING POWER.

SPECIFICATION forming part of Letters Patent N0. 759,574, dated May 10, 1904.

A Application filed February 10, 1904. Serial No. 192,999. (No model.)

To nfl/Z whom t T11/Ly cowl/cern:

Be it known that I, EDGAR OTTO WEIDLER, a citizen of the United States, residing at Oil City, in the county of Venango, State of Pennsylvania, have invented certain new and useful Improvements in Pumping Powers; and I hereby declare the following to be a full, clear, and exact description of the same, reference beingl had to the accompanying drawings, in .to which Figure 1 is a perspective View of a pumping power embodying my invention. Eig. 2 is an enlarged plan view of the same. Fig. 3 is a side elevation thereof, the power-gear or master-gear being in section. Eig. 4 is a plan view of the bed-plate or base of the pumping power, showing the split clamp-soeket for the arbor of the power-gear. Fig. 5 is an end view of the bed-plate looking in the direction 2O o1c the arrow, Fig. 4. Figs. 6, 7, and 8 are detail views of the spindles or arbors of the power-gear and pump-rod wheel and of the powereshaft, respectively.

Like symbols reifer to like parts wherever 2 5 they occur.

My invention relates to the construction of that class of devices, commonlyterm ed p umping powers, which are intended for the simultaneous reciprocation of a plurality of rods or equivalent means for actuating the pumps of a series or group of surrounding oil or similar wells, and has for its object the production of a simple, compact, powerful, and rigid machine wherein the coaeting elements are so constructed and relatively combined as to support the parts against the vi bration incident to the pull and thrust of the load, minimize the wear, and `facilitate repair when required.

Particularly stated, my invention pertains especially to that class of pumping powers wherein are combined with a bed-plate a hori- Zontal power-shaft, a power-gear or mastergear revolving on a stub arbor or pintle, and a pump-rod wheel mounted on or carried by the power-gear, and is directed, lirst, to securing rigidity with ready adjustability of the arbor of the power-gear, and, secondly, to

facility or' adjustment of the stroke of the pumping-rods. In this class of pumping powers, where the load is carried directly by the power-gear or master-gear and the absence oi' the framing above the power-gear subjects the step of the arbor to increased strain and vibration, great rigidity of the arbor, as well as facility of removal i'or repair, is essential, and to secure these requisites I lprovide the bed -plate with a split socket,

which may be east or otherwise formed integral therewith and which is expanded by a wedge or otherwise and tinished by boring,

so that when the wedge is withdrawn the socket will clamp and uniformly support the step ot the arbor against vibration and wear, and such a construction and combination in a pumping power embodies one feature of my invention.

In connection with a stub-arbor stepped in a clamp-socket, as aforesaid, whereby vibration is eounteracted, I employ a power-gear pro- 7o vided with a plurality of arborsockets arranged at diii'erent distances from the arbor of the power-gear, whereby the position of the pump-rod wheel may be changed to alter the length of vstroke of the pump-rods, and such a construction and combinationin a pumping power embodies another feature of my invention.

There are other minor features of invention, all as will hereinafter more 'fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, l indicates an oblong bed plate, limited as to height, preferably in the 8 5 form of a rectangle, and of such length as will afford room for extended journal-bearings 2 3 for the power-shaft, and in alinenient therewith a socket 4 for the reception of a lixed stub-arbor for the power-gear.

Between the journal-bearings 2 3 is an opening 5 in the bed-plate l to accommodate the bevel-pinion of the power-shaft, and in the sides of the pillow-blocks or journal-bearings are hand-holes 6 6 for the introduction and 95 withdrawal oi the nuts 'for the bolts by which the caps 263a of the journal-bearings are secured. The journal-caps 2 3 may be cupped and provided with oil ports or passages to facilitate lubrication of the bearings of the power-shaft.

Adjacent to one end of the bed-plate 1 and in alinement with the journal-bearings 2 3 is a socket 4 for the reception of the fixed stubarbor on which the power-gear or master-gear revolves. This socket 4 is in the form of a split cylinder or socket, having a radial slot 8,(see Fig. 4,) into which is driven a wedge or equivalent means for expanding' the socket, and the socket when so expanded is finished by boring in order that when thereafter the stub-arbor for the power-gear or master-gear is inserted and the wedge withdrawn the socket will grip or clamp and rigidly and uniformly support the step or foot of the stubarbor.

9 indicates flanges on the socket 4 adjacent to the radial slot 8, through which pass the clamp-bolts 10. In lieu of or in addition to said clamping-bolts 10 studs or keys may be.

used in the usual manner to secure the arbor 12 rigidly in the socket 4. l

Surrounding the upper end of the socket 4 and the bearing for the lower e-nd of the powergear hub is the channel or cup 7 for receiving and retaining any lubricant which escapes from the journal oi' the power-gear or mastergear.

13 indicates the power-shaft, journaled in the bearings 2 3 of the bed-plate 1, which may be provided at one end with a pulley 14 and is provided between the bearings 2 3 with a bevel-pinion 15, adapted to engage the teeth oil-channel or annular oil-chamber 16, from which a port or passage leads to the journal for purposes of lubrication.

Surrounding the hub of the power-gear 16 and at dijerent distances therefrom and from the arbor 12 (see Fig. 2) the power-gear 16 is provided with a plurality of sockets 17 18 19 for the reception of the pintle or arbor 20 of the pump-rod wheel 21, said arbor 2O being changed from socket to socket as the length of the stroke of the pump-rods is to be changed.

The spindle or arbor 2O of the pump-rod wheel is adapted to be removably secured in either of the sockets 17, 18, or 19 by means oi' a shoulder on the spindle and a nut 20u or otherwise, and the relation of the arbor 20 of the pump-rod wheel 21 to the arbor 12 of the power-gear will determine the length of the stroke of the pump-rod.

21 indicates the pump-rod disk or pumprod wheel, journaled on the arbor 20, carried by the power-gear or master-gear 16, and said disk or wheel is provided at its periphery with a series of holes 22 for the clevis or similar swivel connections, whereby the pump-rods are secured to the disk or wheel 21 when the device is in operation.

The bed-plate, power-shaft, stub-arbor, power-gear, and pump-rod wheel being constructed and combined as hereinbefore pointed out, the point of application of the Apower will be so located with relation to the plane of the pump-rods and the plane of the bed-plate that a pumping power of great stability, rigidity, and simplicity is obtained, due largely to the manner in which the stub-arbor of the power-gear is stepped on the bed-plate and the arbor of the pump-rod wheel is stepped on the power-gear, whereby facility of adjustment and repair, as well as rigidity of support, is obtained.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is"

1. In a pumping power, the combination with a bed-plate having a split socket for the reception of an arbor, of astub-arbor clamped in the split socket of the bed-plate, a powergear journaled on the stub-arbor, and a powershaft journaled on the bed-plate for actuating the power-gear, substantially as and for the purposes specified. v

2. Tn a pumping power, the combination with a bed-plate having a split socket for the reception of an arbor, of a stub-arbor clamped in the split socket of the bed-plate, a powergear provided with a plurality of sockets located at different distances from its axis, said power-gear journaled on the stub-arbor of the bed-plate, a detachable arbor secured in one of the sockets of the power-gear, a pumprod disk or wheel journaled on the arbor carried by the power-gear, and a power-shaft journaled on the bed-plate for actuating' the power-gear, substantially as and for the purposes specified.

In testimony whereof I aiiix my signature, in presence of two witnesses, this 6th day of February, 1904.
