HOUSEHOLD INCINERA'IOR Filed Feb. 2, 1944 In v'entor Auw, 3 6m Patented Oct. 26, 1948 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to household incinerators, and has particular reference to a novel construction for a rubbish burner.

The principal object of the invention is to provide an exceptionally strong and sturdy construction for a rubbish burner.

Another object is to provide a construction which permits a larger and more rapid flow of air through the burner.

A further object is to provide an arrangement which greatly reduces the flying of sparks when the burner is in use.

Still another object of the invention is to provide a reinforced foot construction for a rubbish burner.

With the above and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in the claim appended thereto.

In the drawings,

Fig. 1 is a perspective view of the novel rubbish burner;

Fig. 2 is a top plan View of the burner, the cover being removed;

Fig. 3 is an enlarged sectional detail on the line 33 of Fig. 1; and

Fig. 4 is an enlarged rear view of the novel supporting foot construction.

It has been found desirable to construct a rubbish burner which is Very strong and sturdy, which will stand up under constant use and abuse, and which will produce a better and hotter flaming fire to more completely combust the rubbish, the parts being so arranged that flying sparks are greatly reduced. To this end, I form the walls, bottom and top of the novel burner with closely adjacent parallel strips which are dished or concaved, and I form the supporting feet by bending up the ends and using reinforcing stays to provide a very strong support.

Referring to the drawings, the novel burner l includes four wall sections ll, of similar construction, a bottom I2, and a removable top l3, each section being formed of a generally rectangular angle frame l5 and longitudinally disposed concave strips It, the parts being preferably secured by welding. If desired, the wall sections may be slightly tapered to facilitate nesting for conserving space for shipping. The wall sections are assembled by seating the contiguous frame sides together and engaging'tabs or fingers IT, see Fig. 2, on each wall section with the contiguous sides of the adjacent wall section, as disclosed in my prior Patent No. 1,536,470 granted May 5, 1925. The bottom section is then dropped in with the cupped or concave portions uppermost to seat on the frame bottoms of the wall sections, and the top is then removably positioned with the cupped or concave portions uppermost to seat over the top edges of the wall sections.

Referring to Figs. 1 and 3, the longitudinal strips are concave, as illustrated, the ends l8,

however, being flat to facilitate welding to the section frame ends. The wall section strips are cupped towards the interior and are spaced closely adjacent so that narrow longitudinal air passages are provided. Positioning the cupped or concave portions to the interior thus not only greatly strengthens the strips but also forms upright fiues to increase the draft and the air flow. The concave strips for the top and bottom serve to permit rapid removal of snow and water, and the bottom concave strips similarly let the ashes fall therethrough. The legs l9 of the wall sections, see Fig. 4, are bent horizontally and then upwardly, and a cross stay 20 is added, the parts being preferably secured by welding.

The above described construction is thus a strong, sturdy burner, which permits a very rapid flow of air through the longitudinal air passages of the burner when it is in operation, the cupped strips holding back sparks, and the enlarged stayed legs increasing the stability and the strength of the burner. main free of ashes, which slide off the concave portions, whereby the effective life of the burner is greatly increased.

While I have described a specific constructional embodiment of my invention, it is obvious that changes in the size, shape, material, and arrangement of the parts may be made to suit different burner designs, without departing from the spirit or the scope of the invention as defined in the appended claim.

I claim:

A burner construction having vertical wall sections, a bottom section, and a top section, said The bottom strips re- REFERENCES CITED The following references are of record in the file of this patent:
