VENTILATING FLUE.
Application filed October 7, 1922. Serial No. 593,104.
To all whom it may concern:
Be it known that I, CARL II. DAHMEN, a citizen of the Republic of Germany, and resident of Allentown, in the county of it Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Ventilating Flues, of which the following is a specification.
his invention relates to certain new and useful improvements in ventilating flues, the object being to provide a structure for ventilating material which surrounds the flues, for instance, bituminous coal, to prevent spontaneous combustion thereof, or for w grainin bins, to prevent overheating of the same, and, in fact, the structure may be used in connection with various other material where such a device will prove useful.
A flue or structure made in accord with my invention comprises a casing of suitable size which is open at one end, and is provided with a series of longitudinal openings having their upper and lower ends on difierent planes, plates constituting one of the sides of the flue being inclined andpreferably attached to the angular faces of serrations formed along the edges of opposite sides of the flue.
My invention is applicable to the inven tion shown and described in an application filed by me July 25, 1922, Serial Number 577,888. The object of my invention is to provide a flue with air inlet openings which are not liable to be clogged by coal, grain, or other material which in use will surround the fine.
In the accompanying drawings which illustrate a perferred form of my invention,
Figure 1 illustrates a perspective view of a portion of a fiue or ventilator made to accord with my invention, and
Figure 2 illustrates a vertical longitudinal section.
The flue or ventilator is made up, by preference, in such form as to be rectangular in cross section, and opposite side walls have serrated edges which provide angular margins to which plates are attached, said plates being of greater length than the angular portion of the side walls to which they are secured; thus constructed, the lower edges of a plate will overlie the upper edges of an adjacent plate, and the lower portion of the serration will close or form a continuation of the sides.
Referring more particularly to the drawings, it will be noted that, as shown, the sides 3 of the flue have serrated opposite edges, the angular portions 4 of said serrations being integral with the sides and constituting guards to prevent the material from entering the ventilator at the ends of openings, as will presently appear and the lower edges 5 together provide means for producing the inlet openings 6 and means for sustaining plates 7 which are of a greater length than the angular longitudinal edges of the serrations, so that when the parts are assembled, the lower edges of successive plates will overlie the uper edges of the plates below. The side pieces prevent lateral entrance of material to the interior of the flue or hollow shaft, and the extended ends prevent upward entrance of material to the flue. The fine is open at its upper end and is provided with a suitable support for maintaining a cover plate 8, and the lower end may be either open or closed, or otherwise constructed to be connected, when desired, to lateral ducts.
One of the primary uses of this invention is to prevent spontaneous combustion of bunker coal, and when used for such purpose, a ventilator is placed in the vessel and its upper end may extend through a hatchway or be positioned above the coal level in order to communicate with the usual draft induced ventilating system, and when so applied, gases that accumulate from the coal will be gathered into and carried off by the flue, either to the atmosphere or to ventilating space above the coal.
In silos, grain bins, etc., the upper covered end of the flue may extend through the building and heat generated will escape to the atmosphere.
Of course, in practice, a number of these ventilating flues may be used, and there will be a constant up-draft through the openings into the flue and out of its up er end. Instead of providing a rectang ar structure, the same may be semi-tubular. In filling coal bunkers, bins, etc, the plates serve as deflectors and prevent the closing of the air inlet apertures.
I claim: flue, serrations projecting outwardly from A ventilating flue about which material the edges of the flue between the plates to may be stacked, said flue having attached form guards for the openings between the 10 thereto angularly disposed plates of such plates and a cov'erplate maintained above 5 length that the lower ends of the plates will the sides of said ventilator.
overlie the upper edges of adjacent plates to provide inlet openings to the interior of the CARL H. DAHMEN.
