Abstract
Abstract A dustless container for disposing of ash generated by wood or coal burning stoves, fireplaces and furnaces. The container may be of any shape desired, however, a conventional twenty-gallon garbage can and lid has been found acceptable. A door is disposed in the side of the container so that ash may be shoveled through the door into the interior of the container. The lid is provided with an opening which is covered with a vacuum adaptor. A conventional vacuum cleaner can then be attached to the vacuum adaptor. A baffle is disposed within the interior of the lid so that suction provided by the vacuum cleaner is evenly dispersed within the container. Thus, any fine fly ash which floats upwardly as ash is loaded into the container will be drawn through the lid and into the vacuum cleaner and will not re-enter the room surrounding the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
An ash disposal apparatus comprising: a generally cylindrical body having a base and an open upper end; a lid configured so as to fit securely over the open upper end of the body, said lid having an opening disposed therein; vacuum adaptor means defining an interior space, and being configured so as to securely cover the opening in the lid, and being capable of being placed in communication with a source of suction; a frustoconical mesh filter disposed within the interior of the vacuum adaptor means, whereby said mesh filter filters out hot and cold particles which may flow into said vacuum adaptor means; a door attached to the cylindrical body whereby access to the interior of the apparatus may be gained by opening said door and through which ash may be introduced into said container, said door being configured such that it forms a chute when opened; a substantially planar and generally circular baffle disposed between the lid opening and the door such that air flowing between the open door and the lid opening must pass between the interior walls of the cylindrical body and the outside circumference of the baffle, such that an even airflow within the apparatus is achieved.
