US3728976A — Portable incinerator

Claim 1

Independent Claim 239 words

Portable incinerator apparatus for reduction of refuse comprising: a metallic housing; a firing chamber provided at the lower end of said housing and being lined with a fireproof material; said firing chamber having an outlet opening for passing emissions from combusted refuse; flue stack provided at the upper end of said housing; a by-pass conduit having a tortuous path for coupling the outlet opening of said firing chamber to said flue stack; a portion of said tortuous path including a conduit portion in which fumes exiting from said firing chamber pass first downwardly from said outlet opening and then upwardly toward said flue stack; a diagonally aligned porous barrier means positioned within an upper portion of said conduit at a location intermediate said firing chamber outlet opening and said flue stack for preventing particulate from passing therethrough; spray means adapted for connection to a water supply and being positioned within said conduit and beneath said water supply for gravity feed of the water to develop a water spray upon one surface of said barrier means; collection means positioned beneath said barrier means and within said conduit for collecting water and particulate carrier by said water to an outlet conduit provided between said collection means and the exterior of said housing, said collection means including a sloping portion forming a part of said tortuous path; a wheel assembly coupled to the base of said housing for rollingly transporting said incinerator.

Claim 2

Dependent Claim 239 words

Portable incinerator apparatus for reduction of refuse comprising: a metallic housing; a firing chamber provided at the lower end of said housing and being lined with a fireproof material; said firing chamber having an outlet opening for passing emissions from combusted refuse; flue stack provided at the upper end of said housing; a by-pass conduit having a tortuous path for coupling the outlet opening of said firing chamber to said flue stack; a portion of said tortuous path including a conduit portion in which fumes exiting from said firing chamber pass first downwardly from said outlet opening and then upwardly toward said flue stack; a diagonally aligned porous barrier means positioned within an upper portion of said conduit at a location intermediate said firing chamber outlet opening and said flue stack for preventing particulate from passing therethrough; spray means adapted for connection to a water supply and being positioned within said conduit and beneath said water supply for gravity feed of the water to develop a water spray upon one surface of said barrier means; collection means positioned beneath said barrier means and within said conduit for collecting water and particulate carrier by said water to an outlet conduit provided between said collection means and the exterior of said housing, said collection means including a sloping portion forming a part of said tortuous path; a wheel assembly coupled to the base of said housing for rollingly transporting said incinerator.

Claim 3

Dependent Claim 43 words

The apparatus of claim 1 further comprising a burner adapted for connection to a fuel gas source and being positioned within the downward portion of said by-pass conduit adjacent said firing chamber for burning any material and/or emission passing into said by-pass conduit.

Claim 4

Dependent Claim 42 words

The apparatus of claim 1 further comprising adjustable chuck means secured to the base of said housing for aligning said incinerator upon the terrain where the incinerator is to be used and to prevent any rolling movement of said incinerator during use.

Claim 5

Dependent Claim 91 words

The apparatus of claim 1 further comprising plural rotatable adjustable grating means positioned above the floor of said firing chamber to thereby provide an ash pit beneath said firing chamber and plural means mounted at the exterior of said metallic housing and coupled to each of said grating means for selectively adjusting said grating means; first door means provided in said housing for gaining access to said ash pit for cleaning purposes; second door means provided in said housing above said first door means for gaining access to said firing chamber.

Claim 6

Dependent Claim 41 words

The apparatus of claim 1 further comprising water storage means mounted upon tHe exterior of said housing above said spray means and being connected thereto by valve means for selectively controlling the flow of water to said spray means by gravity.

Claim 7

Dependent Claim 54 words

The apparatus of claim 1 further comprising a fuel gas container releasably secured to said housing and being connected to said burner means by valve means for selectively controlling the flow of fuel gas to said burner means; said housing being provided with a platform along its exterior for supporting said fuel gas container.

Claim 8

Dependent Claim 43 words

The apparatus of claim 1 wherein said flue stack is pivotally coupled to said housing upper end and is adapted to be pivoted toward a first direction away from the operative position to reduce the overall height of the incinerator during transport thereof.

Claim 9

Dependent Claim 39 words

The apparatus of claim 1 wherein a portion of said tortuous path is comprised of a pair of overlapping spaced inclined ledges positioned below said barrier means for guiding water passing through said barrier means to said collection means.
