ABSTRACT:
The following specification discloses an apparatus and method for providing lifting motion on a substantially symmetrical and compact basis for a pump through a linkage, comprising two members pivotally coupled for relative movement driven by a gear reducer. The first member is driven in a rotational manner with the second member connected thereto being rotationally driven at the same angular velocity, but in the reverse direction thereto. The angular velocity of the members can be controlled by gears, a timing chain and sprockets, or other timed drive means. As the first member rotates with the second member moving around the pivotal connection point at the same angular velocity, a lift point or pump connection is moved in a reciprocating manner to provide lift. The members can be appropriately counterbalanced. The members can also be provided on either side of the gear reducer to provide dual lift points. If a chain is used for timing the members, the chain can be enclosed in a housing with an oil bath. In lieu of counterweights an air balance piston can be used to balance a rod pump.
