  • Patent number: 5333828
    Abstract: A foldable Christmas tree stand having a plurality of legs that can be permanently assembled, yet is foldable in the assembled form. When unfolded it receives and supports a Christmas tree in an upright position, and when folded it occupies a flat, compact, planar space for convenient handling, storage, and shipping. The Christmas tree stand comprises pivotally interconnected legs that pivot about one or more substantially vertical axes. When unfolded, the legs can be locked in position by a locking assembly disposed about the pivot axes of the pivotally interconnected legs there by providing a stable base for mounting a Christmas tree thereto. Additionally, the Christmas tree stand is designed to enable the trunk of the tree to rest in a water supply container, partially full with water thereby keeping the tree moist to extend the tree's life.

  • Patent number: 5333693
    Abstract: A tractor-mounted tree stump puller having articulating components that create a mechanical advantage to remove buried objects or the like from the ground in response to forward movement of the tractor. The implement comprises at least two components pivotally joined to form an articulating structure that shifts from a retracted position to an extended position upon forward movement of the tractor. An articulating structure so formed has a first end pivotally coupled to the tractor, and a second end rigidly attached to a forked structure. Just prior to the removal process, the forked structure is disposed to engage a buried object. With the forked structure engaging a buried object, the tractor moves in a forward direction causing the articulating components to shift from a retracted position to an extended position.
