Abstract
Abstract The grill body is an integral member, preferably made of microcrystalline glass and formed with opposed series of corresponding pairs of upwardly opening saddles at each of two different intermediate levels in two opposed sidewalls. Each pair of saddles receives the opposite ends of a metal bar or the like, to provide two levels of support bars. Preferably, the support bars at each level are not interconnected by cross-bars so they may be removed, cleaned and even replaced individually. Particular gas burner and electric heating element constructions are illustrated.

Claim 1
Independent Claim
153 words
In a barbeque grill, a body comprising: an integral shell formed of heat-resistant glass and having a floor and an upstanding peripheral sidewall extending perimetrically of the floor; opening means formed through the floor for accommodating a heating unit; a gas burner base in the form of an integrally formed upstanding flange on the grill body floor extending in a complete circuit around the opening means through the grill floor; said sidewall, at a lower intermediate level, having two corresponding series of upwardly opening saddles opposed to one another across the floor; said sidewall, at an upper intermediate level, having two corresponding series of upwardly opening saddles opposed to one another across the floor; whereby grill bars may be seated in corresponding twos of the saddles for suspension across the floor at said lower intermediate level for supporting heat radiating bodies, and at said upper intermediate level for supporting food to be grilled.
