My invention’ relates to incinerators which are used for burning up trash of all sorts of burnable materials, including household garbage, and the 2 my door in place and closed before the top cap is mounted on the incinerator base.

Figure 4 is a view from the inside of the door way with my door closed looking in the direction chief use of the incinerator in which my inven tion is employed is for household purposes, being relatively of small sizes of such incinerators. The bodies of these small incinerators in gen eral use are made of concrete of compositions of arrow 4 of Figure 3. which will withstand the heat which is developed Figure 5 is a top plan sectional view of my door by the combustion of the contents of the in 10 on line 5-5 of Figure 3. cinerator, which contents are burned for disposal.

The lower end of the plate 9 terminates in the straight edge 13, Projecting outwardly from the inside of the plate 9 above the bottom edge [3 there is a curved ?ange M which when my door parts are assembled and are placed into position in the incinerator, the straight edge l3 rests on a shoulder 55 of the bar '5, which then acts like a hinge pin connection as and when the straight edge l3 contacts the shoulder l5 and is held in place by the curved ?ange l4 riding over the ?ange 8 of the threshold bar 5.
