5 Claims. (01. 74=41) This invention relates to a counterrotating oted at M to a support or Samson post i5 rising counterbalance particularly applicable onabeam from a case member iii. Pivoted to the base and forming part of a pumping rig or apparatus member in spaced apart relation, as at H is a pair for wells. of upstanding reaction links it.
5 An important object is to provide a means A prime mover such as an electric motor i9 is '5 which will make the load on the motor of a mounted on beam 53 and its main shaft 20 is pumping well more nearly even and continuous journaled in the wall of a casing or housing 2|, throughout the complete cycle so that it will be mounted on said beam. Keyed to the shaft 26 possible to use smaller motors with less consump within the casing 25 is a worm 22 enmeshed with tion of power or electricity. worm wl'ieels 23 keyed to shafts 2t journaled in 10 It is further aimed to carry out the invention walls of said casing 26, at a right angle to the through the use of weights or weighted arms in shaft 23. Weighted members or arms 25 are pairs, on the same or a different shaft, but mountkeyed, one to each of the shafts 2d and are 10- ed on or in the same beam, with one rotating cated on opposite sides of the casing 2i. Said opposite the other, for instance through the memembers 25 carry weights 2% at their free ends 15 dium of gears or reaction links, and at the sides and each member at a crank or wrist pin 27 is of the beam. Such weights or arms are balanced pivotally connected to the upper end of the advertically one above and one below the beam, jacent reaction link i8. with the beam in a horizontal position and then A suitable weight or weights as at 2B is adjustwith the beam in that position, the weights are ably mounted on the beam is as by means of 0 moved forward approximately one-fourth of a screws 29.

The weight of the balls operate in the same direction. or members 26 is approximately one-eighth of the The more specific objects and advantages will fluid load to be lifted by the pump and the weight become apparent from a consideration of the de- 28, when the beam is level and the reaction links 30 scription following taken in connection with acvertical, has a weight equal to the total of the arms 30 companying drawings illustrating an operative or rods '25 plus one-fourth of the fluid lift. The embodiment. weights are adjustable and are but approximate.
In said drawings: Referring to the form of Figures 4, 5 and 6, the Figure 1 is a side elevation of one form of well pumping mechanism at 38 is conventional and pumping device or rig carrying out the invention; similar to that at i ii, the polish rod 3 i, being con- 35 Figure 2 is a vertical sectional view taken subnected to a beam 32 pivoted at 33 at thetop of a stantially on the plane of line 22 of Figure 1; support or Samson post 3 3. Said beam 32 has an Figure 3 is a vertical sectional view taken subextension 35 fastened thereto as at 36. The opstantially on the plane of line 33 of Figure 2; crating prime mover is shown at 3'! in the form Figure 4 is a side elevation of a second form of of an electric motor driving an endless belt 38 40 the invention; trained around a pulley 33 keyed to a shaft 46 Figure 5 is a view taken substantially on the journaled in a bearing or bearings 4| mounted by plane of line 55 of Figure 4; supporting means 42. A crank 43 is fastened to Figure 6 is a detail section taken on the plane shaft G!) and pivoted to a reaction link 34 at 45, 45 of line 6-6 of Figure 4, and which reaction link is loosely connected at 48 to 45 Figure '7 is a horizontal sectional View, fragthe beam 32. mentarily showing another form of the invention. A pulley d! is keyed to the shaft 38 and a belt Referring specifically to the drawings wherein 38 is trained thereover and over a pulley 49, like reference characters designate like or similar keyed to a shaft 58 in suitable bearings 5! sur- 50 parts, and first to Figures 1 to 3, l0 conventionally mounting posts or supports 52. Shaft 59 consists 50 shows an oil or other well pump the same having of aligned sections 53 and 5d journaled in walls of a cylinder or casing H and pumping mechanism a gear casing or box 55 within which a beveled associated therewith, of which I2 is the polish rod gear 55 is keyed to each shaft section 53 and 54. reciprocable therein as usual. Such rod at its Said shaft sections have reduced inward exten- 55 upper end is connected to a beam or lever i3 pivsions 5i, unconnected to each other, and loosely 55 journaled in a sleeve 58. An intermediate beveled gear 59 is enmeshed with the gear 56 and it is carried by a short shaft 88 journaled in the bottom wall of the gear case 55.
Said gear case 55 is rigid on an auxiliary beam 6| having a hooked end 62 loosely engaging a link 63 loosely suspended from a hooked end 64 of the extension beam 35.
Keyed to the shaft 5!] on opposite sides of the supports 52 are weights or arms 65 adapted to swing in opposite directions, and provided with weights 365 at the free ends thereof,
Said arms 55 rotate in opposite directions and function similarly to the arms 25 of the preceding form. It will be realized that the motor 31 the belts 38 and 58 and associated pulleys, drive the shafts it and 50 and through the same operate the beams 32, 6! and 35. Adjustable weights 6! are provided on the auxiliary beam 6! adapted to be secured in adjusted positions by screws as at 68.
A third form of the invention is disclosed in Figure 7. In such figure, a beam is disclosed at Til. On this beam, a gear casing or housing H is mounted in a wall of which, a-shaft I2 is journaled, and which shaft may be driven by a motor such as that shown at IS in Figure 1. On shaft 12, an intermediate beveled gear wheel 13 is keyed, enmeshed with beveled gear wheels 14 and 15 which in turn are enmeshed with an intermediate gear wheel 76 carried by a shaft 11, journaled in a wall of the casing ll. Shafts l2 and ll. are inwardly extended so as to engage sockets at 18 in a bearing block 19, located between the gears M and i5. Said gear wheels M and 15, respectively have sleeves 8B and SI extending therefrom and journaled in walls of the casing H. A shaft 32 passes through the sleeves 88 and 8| and the bearing block 79 and sleeve 8d is fixed to the shaft 82 as by a bolt at $3 and the sleeve 8i is journaled on the shaft 82. Weighted arms 84 and 85, similar to and functioning like those at 25, are employed. Such arm 34 is bolted as at 86 to a crank 81 keyed at 88 to the shaft 82 while weighted arm 35 is bolted as at 89 to a flange 90 on the sleeve 8|, adjacent which, a crank 9! similar to that at 81, is keyed at 92 to the shaft 82. Said cranks 87 and 95, are respectively connected by wrist pins, bolts or the like as at 93 and 9d, to reaction links 95 and 96, respectively, mounted and functioning like those disclosed at E8.
Through operation of the mechanism of Figure '7, the same results are accomplished as with the weights or weighted arms of the other forms, such weighted arms rotating in opposite directions but the cranks 81 and SI rotate in the same direction.
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
