Abstract
Abstract An improved water heater tank leg support assembly includes a plurality of legs formed from a generally rectangular blank by bending the sides of the blank to form a shearing action vertical support member which is spaced by the base. A boss or depression in the base supports the leg member above the floor. The base engages a pan which is suspended beneath a water heater tank. The upstanding vertical legs of the leg support the water heater tank itself.

Total Claims: 5
Claim 1
Independent Claim
174 words
In a water heater of the type including a storage tank having a lower edge, a jacket surrounding the storage tank, a base, support means for maintaining the storage tank lower edge in spaced relation to the base and supported by the base, said jacket also being supported by the base, the improvement comprising, in combination: improved support means, said support means comprising a plurality of formed leg members, each leg member including a generally planar, horizontal run, and a generally transverse vertical run extending from the horizontal run, said horizontal run also including a boss projecting vertically in the opposite direction from the transverse run, said transverse run formed with an upper edge surface inclined relative to the horizontal to define a shear member for cutting through the base upon assembly with the base, said transverse run also including a notch for receipt of and support of the lower edge of the tank, and said horizontal run positioned beneath the base so that the vertical run cuts through and projects through the base.
