  • Patent number: 5577619
    Abstract: Rack forms to be placed on the ground or floor of a steel coil storage area and provided with 4.times.4 or similar timber units to form racks and a rack system for receiving steel coils and holding them off the floor or ground. The rack forms define a pair of spaced-apart channels or troughs into which lumber units are received. The channels include, as securing means, vertical nails or spikes pointing upward. The lumber is driven into the spike as it is received in the trough. Cross members secure the troughs together and define and fix the distance separating the parallel lumber units. A pair of such rack forms can produce a rack much longer than twice their length by providing them with long timber units spanning between the separated pair of rack forms. Parallel rack arrays can be made using a second T-rack form, using similar troughs and spikes to hold timber units in a T-array.

  • Patent number: 5447289
    Abstract: A pry shovel tool for wooden pallet deck board removal and similar purposes is disclosed in several embodiments. All embodiments include a general S-shaped (in cross-section), relatively thin blade made of thin spring metal, whose forward section defines a central cut-out portion sized to allow the blade to receive therein the cross member of the pallet or like and, for the sections of the blade adjoining the cut-out to penetrate below the board to be removed. In one employment, a permanent elongated handle is affixed to the rear portion of the blade. In a second embodiment, a wider blade and cut-out are provided to accommodate wider pallet cross members such as a 4.times.4 timber. A third embodiment has a blade equipped with means for manually attaching removable handles with a short-length handle, an elongated straight handle, and a handle with a 90 degree removable extension section being disclosed.
