Magazines and burn efficiency

Here’s a picture from early in the Baltimore thread of the magazine. It is 5 pieces in total. On the top right side of it you can just make out two of the “vent” holes above the letters BLTO. There are two others in the opposite section.

Does the right upper flange above the vent holes seal tightly to the

upper plate of the top of the heater? Is there a bypass in the upper

plate so when starting the stove or adding fuel that the gases can exit

at the upper plate and not have to go in the normal path downward

through the fire? This is to prevent an explosion of the gases going down

with fresh air to the fire especially when reloading fuel.

This is why the Morning Glory of 1863-1868 received a new patent several

times to clarify the meaning of a baseburner and to enforce his patent

and term "baseburner"is a unique and new idea. I believe this is the first

use of the term baseburner in Littlefields patent.
