  • Patent number: 4213381
    Abstract: Smoldering wood or other solid fuel near the bottom of a vertically elongated enclosure or pit produces heat and smoke which rises freely through the full width of the enclosure or pit to slowly cook food products supported on a plurality of horizontal removable grill racks above the source of heat. A pair of drip collection pans at the bottom of the enclosure or pit on opposite sides of the solid fuel support extend for the full depth of the enclosure or pit. A deflector for drippings having inclined panel portions is arranged above the fuel support and below the lowermost grill rack and diverts food drippings to the two drip collection pans to protect the drippings from contact with the smoldering fuel and preventing excessive heating of the drippings.

  • Patent number: 4201125
    Abstract: Plural heating elements for a corresponding number of self-adjusting smoldering wood supports are independently timed and thermostatically controlled to create a wider range of adjustability and versatility in the cooker to thus widen the variety of products which can be cooked as well as refining and rendering more sensitive the cooking procedures.

  • Patent number: 3986727
    Abstract: To facilitate transporting heavy equipment on forest service roads and the like by means of a low-bed trailer having a gooseneck drawbar, the customary fifth wheel pivotal connection between the towing tractor and trailer is immobilized relative to horizontal or side pivoting and the pivotal connection between the tractor and trailer is placed rearwardly of the tractor adjacent the bottom of the gooseneck. As a result, the tendency for the trailer to "cut the corner" on a sharp curve is substantially eliminated and the trailer will substantially follow the tracks of the tractor around such corners.

  • Patent number: 3974760
    Abstract: In a pit-type slow cooking apparatus, smoldering fuel elements are held on a substantially balanced seesaw support near and above a heating element in the bottom of the pit or enclosure. Food is supported at elevations above the smoldering solid fuel. As the fuel is slowly consumed without open burning or flaming, seesaw movement of the fuel support affords alternate cooling and heat exposure periods for the solid fuel to promote slower and more controllable burning.
