Abstract: An alignment apparatus (28) is provided for use with a supply column (16) including an outer shell (22), a mount (12) configured to couple the outer shell (22) to a ceiling (14), and a plurality of supply lines (24) positioned within the outer shell (22). The supply lines (24) are configured to be coupled to at least one of an electrical supply and a gas supply. The alignment apparatus (28) includes a body member (30) configured to be positioned on the outer shell (22) of the supply column (16), and a plurality of ports (34, 36) formed in the body member (30). The ports (34, 36) are configured to support the supply lines (24) in a predetermined pattern.

Abstract: A gas valve apparatus is configured to receive a gas specific adapter. The apparatus includes a gas valve body having a first keying mechanism, and a cap coupled to the gas valve body. The cap includes a keyed front face having a gas outlet configured to receive the gas specific adapter. The cap also includes a second keying mechanism configured to mate with the first keying mechanism on the gas valve body to permit the cap to be coupled to the valve body.

Abstract: The subject apparatus is a portable tree stand for observation purposes, and generally comprises, as the basic support member, a triangularly-shaped member, basically formed as a right triangle, when observed from the perspective of a side elevational view. Disposed in the leg of the triangular member which is comparable to the hypotenuese side of such triangular member, is an opening which is adapted to hold a longitudinally and vertically extending shaft member, the upper portion of which is affixed in a pivotal manner to the undersurface of a seat structure. The upright leg of the support structure, which leg is comparable to the vertical leg of the triangle, has upper and lower support elements adapted to engage the outer circumference of a tree trunk so as to affix the apparatus in a vertical position along said tree trunk.
