It's a Retort in a ring stand. The retort is a glass flask and the ring 
stand is a metal tripod that can hold such round bottmed flasks or with a 
metal screen over the opening, can be used to heat flat bottomed beakers. 
Most Ring stands come with several nested rings.

diamond discs, both etched and labeled, show edison's signature superimposed 
over a trademark with the statement "a product of the edison laboratories." 


depicted in that trademark logo are two objects that are probably intended 
to be representative of a laboratory. on the right i am guessing is a mortar 
& pestle, and on the left is an object i can not identify. it seems to have 
three legs and a tapered tube of some sort. 


can anyone explain this image? 


best, david harvey
