  • Patent number: 8137049
    Abstract: A rebar separator having a crossbar situated atop one or, preferably, two vibrational insulators which are preferably inflatable cushions. Preferably, there are two or more such crossbars on one or two inflatable cushions. At least one vibrational motor is in contact with at least one crossbar. And preferably each crossbar slopes from a first end to a second end. A source of fluid is in communication with each inflatable cushion. Preferably, the vibrational insulators are placed on top of first and second longitudinal channels of a horizontal rack.
    Type: Grant

  • Patent number: 7625168
    Abstract: A combination pipe kicker/indexer for attachment to a pipe launcher is provided. The pipe kicker includes an articulated arm that is operated by a rotating shaft. The arm has a kicker head that rises up from a frame and moves towards a pipe located in the trough of the pipe launcher. Continued rotation of the shaft causes the kicker head to push the pipe out of the trough. Reversing the shaft rotation retracts the kicker arm into its frame. The indexer includes a plate having two eccentric cam openings and a cam rotatably mounted therein. Rotation of the cams causes either end of the indexer plate to rise up from the frame and urge a section of pipe towards the pipe launcher trough.

  • 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.
