Abstract: A hydraulic pumping assembly provides reciprocating motion to a sucker rod string coupled to a downhole pump. The pumping assembly includes a hydraulic cylinder, a cylinder rod, a telescoping cylinder sleeve for increasing the effective stroke length, and a cylinder base positioned below the hydraulic cylinder. The hydraulic cylinder includes a cylinder barrel, a cylinder head, a piston, and a port configured to direct hydraulic fluid to and from the cylinder barrel. The piston is coupled to the cylinder rod at an upper end of the rod. The cylinder rod slides within the cylinder sleeve, which passes slideably through the cylinder head. The cylinder sleeve moves between an extended position and a retracted position as the piston reciprocates within the cylinder barrel. The cylinder base accommodates the cylinder rod and the telescoping cylinder sleeve in a collapsed position.

Abstract: A timing assembly (200) for a manufactured wood products press (66) is provided. The manufactured wood products press includes a first drive shaft (120) coupled to a first platen (90) and second drive shaft (120) coupled to a second platen (90). The first and second platens are disposed within the manufactured wood products press in an opposed manner. The timing assembly includes a housing (202) and a plurality of timing gears (204) disposed within the housing. The plurality of timing gears are operatively connected to the first and second drive shafts for simultaneously driving the first and second drive shafts in an eccentric path.

Abstract: A press unit (20) for a manufactured wood press (60) is provided. The press unit includes a housing (80), a platen (90), and a drive assembly (76) disposed within the housing. The drive assembly is coupled to the platen to drive the platen in a non-linear motion. More specifically, the drive assembly includes a shaft having concentric and eccentric portions which are disposed on separate axes. Rotation of the eccentric portion about its respective axis causes movement of the platen in the non-linear motion.

Abstract: A press assembly is shown having a plurality of aligned press modules having a lower platen and an oppositely-disposed upper platen, the press modules defining a channel through the press assembly. A resinous wood fiber mat is fed into the channel. The upper and lower platens are driven along synchronized circular paths of travel such that the mat is compressed between the platens and is propelled by the platens through the channel. The platens are connected to eccentric shaft drive assemblies that move the platens along the desired circular path. The action of the eccentric shafts of each module are interconnected and coordinated by gear box units, and the gear box units are interconnected by intermediate gear boxes to synchronize the press assembly. A plurality of motors drives the eccentric shafts, and the supplied power may be distributed by the gear boxes.
