. 1S A devi fforthe purpose stated comprising a. header, an'. entiV wall having its lower rportion .downwardly flared', vthev header and said end wail -having centralj notches'in their lower edges wherebythey maybe engaged over a barvof a 'printing press.v burner tubes supported byr the animos plates securedpupon the upper edges of the header,
The heat will 'be as its upward escape is prevented by' header, burner tubes in the header and the end wall and in communication with the interior of the header, means for supplylng fuel to the header, walls extending between the header and the end wall yand inlined with the side walls of the notches. and cover plates se- 5 .cured upon the upper edge of the header, `the end wall and intermediate walls.
2. A device for the purpose stated comprising ,a header, an end wall, the lheader and the end wall having upwardly extending notches at the centers of their lower edges whereby they may be engaged over a bar, of a printing press, longitudinalwallsextending between the header and the end wall vat the'sides of said notches, cover the end walland the longitudinal walls 'whereby .two parallel chambers having open bottoms arey defined, means .for 'supplying fuel to the header.
` and burner tubes communicating with the headenand supported'by the same and the end wall 20 at the bottoms ofth'e'parallel chambers..
3. An lattachment for'-v printing pressesv includ ying amender,l a pipe for supplying fuel tov thev hea/demand extendiing therefrom, an end wall for supporting' the 25 "ends of'the header tubes remote from'theburner,
partitions between the' burner tubes anciextend: ing from the lheader to said tube supports, and :cover plates mounted on the corresponding' upper edges yof the headerl andl said supports, 'corre- 3Q vsponding cover plates and partitions being spaced to permitr circulation of air.
A4. In an attachment for .printing presses, a header havingindependent 'compartments de- 'lining an intermediate passage opening 35 through the top thereof, burner tubes disposed within the compartments, square supports for 4the ends of .the burner tubes remote from the vheaderpxneans for supplying fuel to the yburner tubes,means for controllingthe flow of fuel .to ..40 .said.tubes, means inythe intermediate air passage -forsecuring the header in .position on a printing press. and a. cover plate for each of the compartments for limitingdiffusion of heat from -the attachment. 45- Y DEWEY FICKES.
