Abstract
Abstract An incinerator having a chamber in which combustion of miscellaneous products occurs to leave a residue in the form of particulate inorganic matter small in weight and volume, and a cleaning system which includes a compressor having a first connection to the chamber for directing air into the chamber for stirring up the dustlike residue and a second connection to the chamber for drawing off the dust-laden air into a cyclone filter or dust separator.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
65 words
Apparatus of the character described comprising an incinerator having a chamber therein for reception of ash following combustion, and means for cleaning ash from said chamber comprising filter means, and air-circulation means including a compressor for directing a flow of air into said chamber to pulverize ash therein and for suctioning ash-laden air out of the chamber back to the compressor through the filter means.
Claim 2
Dependent Claim
65 words
Apparatus of the character described comprising an incinerator having a chamber therein for reception of ash following combustion, and means for cleaning ash from said chamber comprising filter means, and air-circulation means including a compressor for directing a flow of air into said chamber to pulverize ash therein and for suctioning ash-laden air out of the chamber back to the compressor through the filter means.
Claim 3
Dependent Claim
40 words
Apparatus as set forth in claim 1 wherein a burner is mounted in said incinerator, and timing means is provided for operating the burner for a controlled time period, and subsequently operating said cleaning means after a predetermined cooling-off period.
Claim 4
Dependent Claim
60 words
Apparatus as set forth in claim 1 wherein the filter means includes a sealed container, and a disposal bag within the container mounted so as to receive the ash-laden air, said disposal bag being impervious to said ash and pervious to the air whereby the ash will remain in the bag while ash-free air will continue on to the compressor.
Claim 5
Dependent Claim
36 words
Apparatus as set forth in claim 1 wherein said filter means is a cyclone filter, and a disposal bag is connected to the cyclone filter for receiving ash separated from the air by the cyclone filter.
Claim 6
Dependent Claim
37 words
Apparatus as set forth in claim 1 wherein said filter means is a cyclone filter having means for connecting a source of incoming fluid to one portion, and means for connecting a second portion to a drain.
Claim 7
Dependent Claim
36 words
Apparatus as set forth in claim 3 wherein said incoming fluid connecting means includes a valve, and timing means is provided for opening and closing the valve in conjunction with starting and stopping the cleaning means.
Claim 8
Dependent Claim
105 words
Apparatus of the character described comprising an incinerator having a burner therein for burning combustible products, a chamber for reception of ash following combustion, and means for cleaning ash from said chamber comprising filter means, and air circulation means including a compressor, a pipe connecting the compressor with said chamber for directing air into said chamber to agitate ash therein, coupling means connecting said filter means to the compressor for directing air from the filter means to the compressor, and a second pipe connecting the filter means to the incinerator whereby ash-laden air in the incinerator is suctioned toward the compressor through the filter means.
Claim 9
Dependent Claim
105 words
Apparatus of the character described comprising an incinerator having a burner therein for burning combustible products, a chamber for reception of ash following combustion, and means for cleaning ash from said chamber comprising filter means, and air circulation means including a compressor, a pipe connecting the compressor with said chamber for directing air into said chamber to agitate ash therein, coupling means connecting said filter means to the compressor for directing air from the filter means to the compressor, and a second pipe connecting the filter means to the incinerator whereby ash-laden air in the incinerator is suctioned toward the compressor through the filter means.
Claim 10
Dependent Claim
51 words
Apparatus as set forth in claim 7 wherein the filter means includes a sealed container connected to said coupling means, said second pipe has one end extending into the container, and a disposal bag is attached to said one end of the second pipe to receive said ash-laden air flowing therefrom.
Claim 11
Dependent Claim
92 words
Apparatus as set forth in claim 7 wherein said filter means is a cyclone filter, said second pipe has one end extending into the filter at one end thereof and at an angle such that air entering the filter therefrom will flow in a circular pattern, a disposal bag is attached to the filter to receive ash from said circulating air, and said coupling means includes a third pipe having one end connected to the compressor and its opposite end extending into the filter whereby filtered air is suctioned to the compressor.
Claim 12
Dependent Claim
115 words
Apparatus as set forth in claim 7 wherein the filter means is a cyclone filter, said second pipe has one end extending into the filter at one end thereof and at an angle such that air entering the filter therefrom will flow in a circular pattern, said coupling means includes a third pipe having one end connected to the compressor and its opposite end extending into the filter whereby filtered air is suctioned to the compressor, means is provided at the lower end of the filter for connection to a drain, and conduit means is connected to an upper portion of the filter for supplying for connecting the filter to a source of flushing fluid.
Claim 13
Dependent Claim
34 words
Apparatus as set forth in claim 10 wherein said conduit means includes a valve, and timing means is provided for opening and closing the valve in conjunction with starting and stopping the cleaning means.
