In an atmospheric gas-burner having the deflectors as claimed in claim 4, forming such deflectors of or upon a single piece such as 1, substantially as described. (6.) In an atmospheric gas-burner having deflectors as claimed in claim 4 or claim 5, the combination with such deflectors of a screen in about the position shown in Figs. 1 and 5. (7.) In an atmospheric gas-burner as claimed in claim 1, the combination therewith of a ring supply-pipe connected with each of the Bunsen tubes. (8.) The combination with an inverted burner of the construction claimed in claim 1 of an annular reflector, substantially as and for the purpose described. (9.) The combination with an inverted burner of the construction claimed in claim 1 of a chimney having about twice the diameter of the common mixing-chamber, substantially as described. (10.) The combination with an inverted burner of the construction claimed in claim 1 of the combined reflector and chimney arranged and secured substantially as described with reference to Fig. 2 of the drawings. (11.) In an inverted burner of the construction claimed in claim 1, telescopic joints in the Bunsen tubes, substantially as and for the purpose described. (12.)
