CHARLES C. CHRISTENSEN AND ROBERT IVICCALPIN, OF CHICAGO, ILLINOIS.

INCINERATOR.

Application led December 2, 1922. Serial No. 604,478.

T o al] whom t may concern:

Be it known' that we, CHARLES C.l CHRIS- TENsEN and Ronnnr MCCALPIN, citizens of the United States of America, and residents of Chicago, Cook County, Illinois, have invented a certain new and useful Improvement in Incinerators, of which the following is a specification.

Our invention relates to an improvement in incinerators and particularly to an incinerator for burning refuse suchas garbage.

An object of our invention is to provide an incinerator in which the refuse, such as garbage, will be entirely consumed without the production of any odor or any smoke. By our invention the flame is projected downward upon the material in the fire-pot and thus the refuse is progressively dried and then burned, starting from the top; the liquid in the material draining downward to the bottom of the pot. In this way the liq-l uid does not interfere in any way with the efficient operation of the flame, and, furthermore, the burning can commence almost im-. mediately without first necessitating the drying of the entire mass of refuse.

A further object of our invention is to provide a container for the refuse which can be easily and quickly removed from the enclosing housing for the purpose of loading. These "and other features and objects of -our invention will be more readily understood by having reference to the accompanying drawings, in which we have illustrated one embodiment of our invention.

In the drawings- Figure 1 is a front elevation of an inlcinerator embodying the features of our in-v vention;

2 is a vertical sectional view of the same; l Fig. 3 is a longitudinal sectional view; and Fig. 4 is a detail sectional v'iewvshowing a portion of the mounting for the fire-pot.

As illustrated, our incinerator comprises essentially a fire-pot 5 mounted within an enclosing housing 6. This housing is preferably made with an auxiliary wall 7 passing around the rear and sides of the housing-,

separated from'the main wall by a dead air space 8. Likewise mounted below the top of the housing 6 is an auxiliary' wall 9 separated from vthe top wall bythe dead air space 10. 4A suitable hood 11 is mounted upon the top of the housing and passin through the top of the housing and upwar through the hood is the exhaust flue 12. This exhaust flue extends downward so that the lower end 13 of the same is located to one side of and below the upper edge 14 Vof the fire-pot.

The fire-pot is mounted upon a grate 15 to the sides of which are secured rails 16. These rails are guided over rollers 17 mounted in suitable brackets 18 secured tothe bot-"65 j tom of the housing. The roller'19 is .likewise provided at the front end of the housing for engaging the upper surface of each of the rails. Carried by the brackets 20 (see Fig. 4) secured to the grate 15 there is an ash pan 21. Likewise carried by the grate and extending upward therefrom is a front plate'22wl1ich covers an opening in the front of the housing, which opening is provided for the purpose of enabling the 27 into which ail is drawn through `openings v 28 to thus create an efficient and hot flame. The burner can be ignited in any suitable waysuch' as b a pilot 29. The sight-window 30 is pre erably provided in the front' of the housing so that the progress of' thev combustion may be observed.

In operation the fire-pot is lfirst withdrawn from the housing sufficiently to permit the loading of the fire-pot. Complete' withdrawal of the lire-pot is prevented by reason of the `projections 31 on the inner end of the rails striking the-upper roller 19.y

After being loaded the fire-pot is shoved back into the housing and .the flame then ignited. This flame is projected downward upon the .material which, if garbage, is somewhat dilicult to consume and must first be dried. The flame striking the upper surface of the refuse progressively dries and then ignites and burns the same. Any smoke .which may arise in the initial drying must 'pass through the path of theflame and 1s thus consumed. A large quantity of oxygen is necessary in order 'brmg about complete combustion, and m our constructlon this oxygen is provided by the air being drawn through the inlet opening 32 provided in the front plate 22 as well as from the smaller opening 33 provided below the fire-pot. The air passing through the inlet opening 32 passes over the top of the firepot and thence downward into the material; while the air passingl t-hrough the inlet opening 33 'passes through the grate 15 and thence upward through the material. The air isv prevented from passing directly up the flue by means of the trough-shaped member 35 carriedby the grate 15 and extending upwardly therefrom.v By having the lower end 13 of the exhaust llue 12 extend below the upper edge of the fire-pot, the air is prevented from passing directly acro the top of the .iireepot as this construction forms a,

I baille so that the draught is broken sul'liciently to cause the air to be forced downward into the material and thus bring about a complete burning of the'same. IAs the burning progresses the material is gradually dried and then burned, the liquid seeping downward through thematerial and thus mterteringinvany waywwiththe eiliciegtv' operation of the burner. The fire-po? is so formed that the flame reaches Substantially all portions of the same and thus all the material is effectively consumed and this is accomplished without the emission vof any smoke, for, as before stated, any smoke which may arise from the material must pass through the path of the flame and is there consumed.

While we have illustrated and described one particular embodiment of our invention v it will b e understood that we do not wish to l ing from tion.

be limit/ed to the exact construction shown.

modifications may be made without dep`artthe spirit andintent of our invenfuse, a housing enclosing' the top of said con ramene downward into the material contained therein, and an exit flue extending upward through said housing the lower end of said flue terminating below and outside of the upper edge of said container.
