Schruder has employed an ingenious design for this massive dish-cross, making it a very rare example of exceptional size. The dish cross uses three bar supports fitted with pins that engage with a geared column within the heater base. As one leg extends or retracts, the others simultaneously shift in unison. The only other known examples of this extremely rare form of dish cross include one with alternating wick burners is by Paul Crespin, 1738, in the Egremont Collection at Petworth House, Sussex, and another by John Swift of 1754 sold from the collection of Mrs. C.
