Abstract
A filter member (98) is mounted on the inside of a sidewall (16) of a receptacle (10), in a position covering an opening (76) in the sidewall (16). A vacuum cleaner suction hose attachment (122) is provided on the opposite side of such opening (76). The receptacle (10) is a closed container when used, except for a sidewall inlet (38) in the sidewall (14) which is opposite the filter carrying wall (16). Ashes (134) are introduced into the inlet opening (38) and dumped into an ash pan (52) contained within the lower portion of the receptacle (10). The vacuum cleaner (130) draws the fine dust to the filter member (98). The fine ash dust is collected by the filter member (98) or is drawn into the vacuum cleaner (130). When the ash pan (52) needs to be emptied, the top (22) of the receptacle (10) is swung open. The attendant sticks his or her hand down into the receptacle (10) and grabs a handle portion (64) of the dust pan (52), moves such handle (64) from a folded down position up into an upright position and uses it for removing the ash pan (52) out from the receptacle (10).
