  • Patent number: 8454296
    Abstract: Apparatus and methods for moving a tubular member to and from an elevated drilling rig floor. A support structure has an elongate indentation in its upper surface. A ramp assembly comprises telescoping assemblies having nested tubular elements extendable between retracted and deployed positions, thus forming a guide extending from the elongate indentation towards the drilling rig floor. Indexers may urge the tubular member towards or away from the elongate indentation. Kickers may urge the tubular member into or out of the elongate indentation, and may be operable via actuators which also operate the indexers.

  • Patent number: 7367445
    Abstract: A case feeder mechanism, used in quantities of two or more in a horizontal magazine, feeds cases to a removal position at the discharge end of the magazine, for extracting and processing by a case erecting machine. Each mechanism has two U-shaped channels, a sliding ratchet pawl channel and a fixed ratchet pawl channel, each containing a row of ratchet pawls. Each sliding ratchet pawl channel pushes the ratchet pawls against the back of the case group, driving the group towards the removal position. Individual sensing valves determine when the lead case is in the removal position and control each sliding ratchet pawl channel independently. Each fixed ratchet pawl channel holds the ratchet pawls in position, supporting the case group during resetting of the sliding ratchet pawl channel. To reload, cases are simply inserted, preferably in bundles, behind the existing case group.

  • Patent number: 7131527
    Abstract: A lumber unscrambler and conveyor having first and second rigid units mounted at an incline on a support structure. Each unit has a plurality of spaced apart parallel plates in series along the incline and parallel thereto. The plates on the respective first and second units are interleaved in alternate relation. The plates have an upper article supporting surface and a leading edge generally transverse to the incline. The leading edge of plates proximate the in-feed end are of greater depth than those further along the path toward the out-feed end. The units are supported on the support structure to move relative thereto and one another. The units are driven in synchronized out of phase relation reciprocating along the inclined path. A hopper at the in-feed end receives and holds a supply of lumber pieces of selected dimension and as the plates reciprocate they move pieces of the lumber from the hopper to the out-feed end discharging normally only a single stick one after another.

  • Patent number: 5605427
    Abstract: A level gravity conveyor provides a plurality of individual load-engaging support pads aligned longitudinally along the conveyor. The pads are movably supported on runway segments which extend longitudinally. Each runway segment defines an upper raceway surface which movably supports the pad, which upper surface in the preferred embodiment is defined by a plurality of support rollers. The runway segments are alternately raised and lowered so that, when in a raised position, the upper surfaces slope downward in the forward direction. The pads engage and vertically lift the loads when the runway segments are in the raised position, whereby the weight of the loads causes the pads to move downwardly by gravity along the inclined upper surfaces to forwardly advance the loads through a small distance.

  • Patent number: 4432449
    Abstract: A one man operable, mobile, field usable log cutting device is provided for quickly and easily loading, handling and transversely cutting of heavy logs to yield finished log segments or discs. The device includes a rotatable, powered saw blade along with an elevated, shiftable, log support for manually moving a supported log into a saw blade for cutting purposes. A manually operable, pivotal, knee-action log advancer is also provided for selective lifting and axial shifting of a log towards a limit stop for determining disc thickness. As disc-like log segments are successively cut, they fall by gravity towards an underlying conveyor for transporting the segments away from the device; conveyor damage from falling segments is prevented through use of a pivotal, spring cushioned, basket-like log segment catcher disposed below the saw blade which engages the falling log segments, turns the same and safely deposits the segments onto the conveyor.

    Abstract: A conveyor for moving uniformly spaced-apart cylindrical articles transversely of their polar axes comprises a pair of parallel sawtooth rails, paired lifting and lowering levers on common pivots disposed along the rails in correspondence with each toothed portion of a rail, and cams for sequentially pivoting the lifting levers. The paired sawtooth elements include a stop surface and an inclined surface extending downwardly therefrom in the direction of article movement. The lowering lever is resiliently pivoted to an upper position independently of the lifting lever, and is downwardly pivotable by an article as it rolls down an inclined surface. Pivotation of the lowering lever to upper position permits the lifting lever gravitationally to pivot below an inclined surface.
