H. M. SHEER HEATER Filed Jan. 19, 1924 329- Patented Dec. 2, 1924.
MNETED STATES HENRY M. SHEER, OF QUINCY, ILLINOIS.
HEATER.
Application filed January 19, 1924. Serial No. 687,355.
To all 20 7mm it may concern.
Be it known that I, HENRY M. SHEER, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Impnwemcnts in Heaters, of Which the following is a specification.
.Evly invention relates to an improven'ie-nt in heaters. The object is to insure against explosion due to inflammable or explosive sub stances being drawn into the flame.
This particular form of my invention con sists of a radiator or drum With a spreader at the top and a gauze cylinder at the bottom, all of which surrounds and contains a burner.
In the accompanying drawings:
Figure 1 is a section; and
Figure 2 is a View partly in section showing members of the device separated from each other.
A represents a Wire gauze cylinder hav ing a closed bottom 1 at the lower end and a sheet metal binding 2 at the top, and
' o is a burner, Which, and also the gauze cylinder, are preferably supported on the gas feed pipe L.
A drum or radiator 5 is removably supported on the upper end of the cylinder, and this has a spreader 6 at the top with a downwardly crimped flange 7 at the outer edge, thus providing space 8 between it and the flange 9 at the top of the drum or radiator for the easy and quick escape of the products of combustion from the burner 3, thus af- .lording ample space above and around the upper end of the burner for the expansion and escape of the products of combustion and for preventing back pressure, thus re ducing the possibility of explosion due to sucking in inflammable or explosive matter through the bottom, to a minimum if not absolutely preventing it, due tothe large space afforded by the drum radiator and the spreader for the rapid escape of the products of combustion which in this Way are not affected by any back pressure.
Thus it Will be seen that this Whole device is constructed upon the theory that danger of ignition and explosion due to sucking in explosive or inflammable matter through the bottom is altogether eliminated or in any event is reduced to a minimum due to the large free space above the burner and the unrestricted circulation beneath the spreader which absolutely precludes back pressure upon the flame. In other Words, as long as there is no back pressure, the flame will ascend and get out of the Way rather than back fire or extend down to ignite anything drawn in at the bottom. To repeat, it is the freedom of escape at the top that insures a constant upward motion of the flame, which course it naturally takes as the natural path of least resistance.
Not only is it true that the deflector provides a free and unrestricted out-let for the products of combustion preventing back pressure, but also it is equally true that this free outlet of products of combustion will increase the volume of air drawn in through the screen and produce suction due to the fine mesh of the gauze screen. This suction Will draw fine dust and gas through the gauze screen in sufficient volume to become ignited as it is drawn into the flame of the burner from underneath and the flame Will travel back to the inside surface of the screen but Will not ignite the gas or dust on the opposite side, that is to say, the outside surface of the screen. products of combustion can not ignite the gas or dust unless the flame extends beyond the outer edge of the spreader and this, of course, can not happen.
I claim:
An article of the character described ineluding a burner, a Wire gauze screen surrounding the burner and having a closed sheet-metal bottom and a binding at the top, means for supporting the burner and screen,
a drum having a circumferential bead on the inner surface thereof for removably supporting the drum on the binding of the screen, and a spreader connected With the drum.
In testimony whereof I aflix my signature.
HENRY M. SHEER.
The escaping.
