Patent ID: 8152123

Claim:
A tank retaining apparatus for selectively holding a cylindrical tank in an inverted position including an adjustable positionable and replaceable retaining cup, said tank retaining apparatus comprising: A. a bracket housing means defining a tank receiving zone for selectively receiving and retaining of a cylindrical tank therein positioned inverted; B. a lower mounting support for receiving the upper portion of the inverted cylindrical tank therein to facilitate selective retaining thereof within said tank receiving zone, said lower mounting support being positioned immediately below said tank receiving zone; C. a rotatable head assembly rotatably mounted to said bracket housing means at a position above said tank receiving zone for selectively engaging and retaining of an inverted cylindrical tank therewithin, said rotatable head assembly including; (1) a rotatable head member rotatably secured to said bracket housing means and defining a plurality of head apertures therein; (2) a retaining cup detachably attached to said rotating head member and being selectively engagable with respect to an inverted cylindrical tank positioned within said tank receiving zone for selective retaining thereof therewithin, said retaining cup being adjustably attachable to said rotating head member at a plurality of different positions, said retaining cup including: (a) a mounting block means being selectively attachable to said rotatable head member at a plurality of different positions, said mounting block means defining a plurality of mounting block apertures therein to facilitate detachable attachment thereof with respect to said plurality of head apertures defined in said rotatable head member, said mounting block apertures being positioned to align with said head apertures to further facilitate detachable attachment therebetween, said mounting block means defining fewer mounting block apertures therein than the number of said head apertures defined in said rotatable head member to provide adjustability in the position of attachment of said retaining cup with respect to said rotatable member; and (b) an arcuate retaining plate attached to said mounting block extending outwardly therefrom, said arcuate retaining plate providing an abutment surface positionable in abutment with an inverted cylindrical tank positioned in said tank receiving zone for selective retaining thereof therewithin.
