PUMP JACK.
Application filed March 14, 1924. Serial No; 699,232.
To all. whom it may concern:
Be it known that. I, Leo J. Hess, acitizen of the United States, residing at Shakopee, in the county of Scott and State of Minnesota, have invented certain new and useful Improvements in Pump Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art t-o'which it appertains to-makeand use the same.
My invention relates to a power transmission device or mechanismgenerally known" to the trade as a pump jack, and
t which mechanism transforms the rotary motion of an engine-driven shaft to a reciprocating motion applied to the pump. Among other things, the invention involves a rocking beam or intermediately pivoted lever slotted at one end, and a pair of laterally spaced gears rigidly connected for common rotation by a wrist pin that works in the slot of said lever. The lever works between the gears and the gears are given simultaneous rotation by a pair of pinions or a wide-faced pinion carried by a shaft to which the power is applied, preferably by a pulley directly secured to said shaft. These features and others will be more fully described in connection with the accompanying drawings, which illustrate the invention and wherein like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. l is a. side elevation showing the complete pump jack;
Fig. 2 is a transverse vertical section taken on the line 22 of Fig. 1;
Fig. 3 is a front elevation of the pump 'ack;
1 Fig. 4; is a plan View of the pump jack with the upper portion or hood-like cover of the case removed; and
Fig. 5 is a section taken through the complete pump jack approximately on the line 55 of Fig. 4.
The numeral 6 indicates a box-like oilcontaining case, preferably of rectangular form. The numerals 7 and 8 indicate rectangular marginal supplemental box sections of approximately the same horizontal form as the box 6, provided with supplemental shaft bearings 9, 10 and 11, and connecting flanges 12, which latter are preferably connected by short nut-equipped bolts 13. The lower supplemental frame section 7-, at longitudinal sides, has depending flanges 14 that lit groove-like seats 15 formedinthe upper portion of the box 6 near its sides. Long nut-equipped bolts 16 are passed through perforations in the flanges 12- and through anchoring lugs 17 shownas cast integral with and projected outward fro-m the lower side portions of the box or case 6. The outer ends of the shaftbearings made up of the supplemental bearings 9-9 and 10-10 are closed, and the outer end of one of the bearings 11 is also closed, while the other bearing 11 is open,
so that a shaft, presently to be noted,ma-y extend therethrough. The upper supplemental box section 8 is shown as provided with a projecting rim flange, which, by short nut-equipped bolts 18, is detachably secured to the correspondingly formed flange of a hood-like cover 19.
Mounted in the bearings 10 is a rock shaft 20 and mounted in the bearings 11 is a power-transmitting shaft 21. lVorking within the case is a pair of laterally spaced spur gears 22 of the same diameter and same number of teeth, and these gears are provided with outwardly projecting trunnions or short shafts 23 that are journaled in the bearings 10. The shaft 21 is provided with spur pinions 24 that mesh with the gears 22 and impart simultaneous and like rotary motion thereto. The two gears 22 are connected by a wrist pin 25 that works in a long slot 26 of an oscillatory lever or walking beam 27 having a. hub 28 pivotally mounted on the rock shaft 20. The lever 27 projects through a slot 29 in the supplemental frame sections 7 and 8 and, as shown in Fig. 1, is pivotally connected to a link or rod 30, which, in turn, will be connected to the pump rod 30. The numeral 31 indicates a pulley secured to that end of the shaft 21 that projects through the open end of the bearing 11.
It will be noted that the gears 22 are arranged to run in oil 1 contained in the box or main case section 6, sothat all of the parts will be kept well lubricated by splashing and dropping of the oil. The duplex arrangement of gears and pinions supports the wrist pin 25 at both ends and relieves the same from torque strains tending to tilt the same and to put the bearings of the gears under undue strain, such as would be produced by force applied to a wrist pin carried by one such gear. Also,
the slotted end of the motion-transforming lever or walking beam is carried between the gears, where it will not only be kept well lubricated but will be carried into and out of the oil.
The several parts that make up the casing are adapted to be independently cast and quickly assembled. When the bolts 16 are removed, leaving the bolts 13 applied, the supplemental case sections 7 and 8 and alsothe cover 19, if desired, together with the working parts of the jack or power-transmitting device, may be removed from the main case or box without disturbing any of the adjustments of the said running parts and, of course, they may be reapplied by reverse operation.
hat I claim is:
1. A pump jack comprising a box-like main case section, a supplemental case section detachably seated on said main case section, a pair of laterally spaced spur gears ournaled to said supplemental case pin is' arranged to Work, and a driving shaft equipped with pinions meshing with said two gears, said lever, gears, pinions and their shafts being removable from said main case section with said supplemental case section. 1
2. The, structure defined in claim 1 in which said supplemental case section is made up of two parts connected by a horizontal joint that splits the bearings that support said lever, gears and pinion equipped shaft, the parts of said supplemental section being detachably connected by means independent of the means that connects the composite supplemental case section to the main case section.
In testimony whereof I afiix my signature.
LEO J. HUSS.
