Oct. 1, 1968 c. T. HEITZ v COVER FOR-TRASH BURNERS Filed Nov. 22, 1966 I ----------n I,
INVENTOR. CHARLES T5 5: ITZ
ATTORNEY FIG.
United States Patent 3,403,644 COVER FOR TRASH BURNERS Charles T. Heitz, 9333 NE. 47th Ave., Portland, Oreg. 97228 Filed Nov. 22, 1966, Ser. No. 596,226 3 Claims. (Cl. 110-18) ABSTRACT OF THE DISCLOSURE A trash burner cover has an outer ring which is adapted to seat on the top edge of a trash burner and which supports a wire mesh in the centralportion thereof. The ring has an inturned flange which supports the wire mesh. Such wire mesh is dome-shaped to make it structurally strong as well as stable under temperature changes, and is held in such dome shape by outward hearing engagement around its periphery with the ring. The wire mesh initially is cut to a larger diameter than that portion of the ring against which it bears whereby to assume such dome shape when installed and to be maintained in such configuration.
This invention relates to new and useful improvements in covers for trash burners.
A primary objective of the present invention is to provide a cover of the type described which is simplified in construction and inexpensive to manufacture and which at the same time has a novel structural arrangement making it rigid and rugged in use.
More particularly, it is an object of the present invention to provide a cover for trash burners which has an outer peripheral frame member and a central screen member secured thereto. The frame member has means for removably engaging a trash burner container and further has an inwardly and upwardly directed flange portion to which the screen is secured. The screen is secured to the peripheral frame member in an arched position in a manner and for reasons to be described hereinafter. The invention will be better understood and additional objects and advantages will become apparent from the following description taken in connection with the accompanying drawings which illustrate a preferred form of the device.
In the drawings:
FIGURE 1 is a fragmentary elevational view of a trash burner showing the cover of the present invention seated thereon;
FIGURE 2 is a top plan view of the present cover; and
FIGURE 3 is an enlarged, fragmentary sectional view taken on the line 33 of FIGURE 2.
Referring now in particular to the drawings, the present cover is designated generally by the numeral and is intended for use on trash burners 12. Such trash burners are generally cylindrical in shape and compise for example a barrel-type structure having an upper, outwardly rolled flange or rib 14.
The invention resides in a cover 10 for trash burners 12, and comprises an annular frame member 16 which as best seen in FIGURE 3 has a body portion 18 which exextends substantially parallel to the axis of the frame member. The upper end of the body. portion 18 leads into an outwardly directed, arcuate portion 20 and the lower end thereof leads into an inwardly and upwardly inclined flange portion 22. The arcuate portion 20 has a radius 3,403,644 Patented Oct. 1, 1968 "ice of curvature corresponding substantially to the radius of curvature of the rolled flange 14 so as to provide good seating engagement of the frame member on the trash burner. Also, as seen in FIGURE 3, flange portion 22 is straight walled. The cross sectional configuration of the frame member makes it rigid for the intended purpose.
The central open area of the frame 16 is covered by screen or wire mesh 24 having a domed or arched configuration, as best seen in FIGURE 1. Such domed configuration facilitates the use of a rather lightweight wire mesh and yet provides a rigid structure.
The domed configuration of the screen 24 is accomplished by cutting a piece of screen of a diameter slightly larger than the inside diameter of the body portion 18 and then forcing it into engagement with the inwardly directed surface of the body portion 18 to form the dome shape. The dome shape is maintained by compressed engagement of the peripheral edge of the screen in the pocket formed at the juncture between the body portion 18 and flange 22.
It is desirable that the screen 24 be secured to the frame member to prevent accidental displacement, and for this purpose a few spot welds 26 are provided between the mesh and the flange portion 22.
The present cover for trash burners thus provides a structure which is inexpensive to manufacture and which is attractive in appearance. Furthermore, the cover, being formed simply of the lightweight frame member 16 and the screen center, is light in weight but nevertheless the structure thereof makes it rugged in use. The covers will nest one within the other to provide minimum space for storage and shipment.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims. For example, the cover may be rectangular or any other desired shape and does not have to be circular as shown.
Having thus described my invention, I claim:
1. A cover for trash burners comprising:
(a) an outer peripheral frame member defining a central area and having a bodyportion extending substantially parallel to the axis of said frame member,
(b) an outwardly directed portion on said body portion arranged to support the cover on a trash burner,
(c) inwardly directed flange means on said body portion,
(d) and a perforate member seated on said flange means covering said central area,
(e) said perforate member being domed for increasing its structural rigidity and stability,
(f) said perforate member in a flat condition thereof having a diameter greater than the diameter of said frame member at the juncture of said flange means with said frame member, whereby said perforate members is held in its said domed condition by outward bearing engagement around its periphery with the body portion.
2. The cover for trash burners of claim 1 wherein said flange means is angled upwardly at approximately the same angle as the desired domed angleof said perforate member whereby to form a seat which is engaged flatwise by outer portions of said perforate member.
' (a) said flange means is angled upwardly from a' lower portion of said body portion to form a pocket against which the outer edge of said perforate member bears,
(b) said flange means being angled upwardly at approximately the same angle as the desired domed angle of said perforate member whereby to form a seat which is engaged fiatwise by outer portions of said perforate member.
