Abstract: This present invention provides a novel form of endless drive track for snow vehicles and the like, comprising: an endless underlying drive support belt with a flat inner surface with lateral edges having a drive mechanism thereon. An outer surface comprising a plurality of tread blocks moulded transversely to the endless underlying drive support belt, the tread blocks having a greater length than the width of the endless underlying drive support belt. The tread blocks have inward angles extending outward from the lateral edges of the endless underlying drive support belt. The lower portion of the tread blocks has a solid base extending upwardly to a point where the tread blocks have a plurality of slots. The slots are strategically located in the tread blocks to cause a staggered pattern of tread sections with adjacent blocks.

Abstract: A self-watering vertical supporting planter includes a growing medium cavity formed by the combination of outer and inner walls fixed to a bottom. The inner walls are fixed to a top and bottom forming a water reservoir with a centrally located sleeve to support a vertical telescopic support pole and pole cap fixed at its upper end. The reservoir is fixed to the bottom of the growing medium cavity. The reservoir has a filler hole and wick ports for self-watering of the growing medium. A plurality of strings are attached to the pole cap and the outer walls by means of hook-like elements fixed to the outer edges of the pole cap and the outer walls. The strings inclined with respect to the vertical form individual supports for vine type plants such as beans, tomatoes and cucumbers.
