Ashtray with devices for extinguishing smoking cigarettes
 An ashtray is provided with devices for extinguishing smoking cigarettes, including an open socket under which is affixed coacting pincers. These may be a pair of spring biased plates or a thin plate having a small diameter hole therethrough. Pincer action is attained by making radial cuts about the hole to produce a saw-tooth spring edge. When a smoking cigarette is inserted through the pincer arrangement, the edges of the pincers pinch the end of the smoking cigarette just behind the hard, burning tip. Withdrawal of the cigarette causes the burning tip portion to be pushed off allowing it to fall automatically into a reservoir in the bottom of the ashtray.
