Application April 8, 1941, Serial No. 387,403

12 Claims. (c1. 131-237) This invention relates to extinguishing devices for cigarettes and the like, and has particular reference to extinguishing devices which are moved into extinguishing position by the op eration of a heat responsive member adjacent the lighted end of a cigarette. One object of the invention is to provide an improved device of this general character in which the heat responsive memberwill shift an extinguishing hood both toward and from the cigarette so that the device automatically opens up after the cigarette has been extinguished. A further object is to provide a device of the automatically resetting type in which there will be a substantial dwell in the extinguishing position even after the cigarette has cooled to the point where the heat responsive member tends to return to inactive position. Other objects will appear from the following description and claims.

The ash tray II) has a cigarette rest it attached thereto and having a portion extending inwardly of the tray. For reasons which will appear below. this rest is'preferably curved to con form closely to the shape of the cigarette. On one side the rest is provided with ears 12 which support a pin [3 upon which is pivoted at M a This hood member can swing from the inactive position shown in full lines in Fig. 2 to theextinguishing position shown in dotted lines in that figure. Attached to a downwardly extending bracket l6, preferably formed integral with the rest, is a helical coil ll formed of a bi-metallic strip or-ribbon. This coil 'extends closely adjacent the end of the rest and is exposed by a concave notch l8 formed therein. When a cigarette is laid on the rest 'rio action' will be produced until it has burned backsufii ciently to heat up the coil l'l. When this occurs its end l9, which extends along the side of the rest underneath 'the pin l3 (Fig. 5),wi1l be raised by the tendency of the coil to twist'under heat, Were the end of the extinguisher ill to be at-fl tached directly to the hood -l5 the latter would be moved into its entinguishing position when the coil was heated and would move back again when the coil again cooled off. This operation. however, would tend toproduce a flutteringof the' hood while in contact with the cigarette and would also require a very substantial movement of the end of the coil. In accordance with the present invention both of these objections Zare avoided by introducing a lost motion connection' between the bi-metallic strip and the-hood 15.

For this purpose a separate member 20 is-em ployed, best shown in Fig. 6. This member 'has a portion [2 coiled around the pin I 3 to serve as a bearing, and an underlying portion 22 to which the strip is connected. The portion 2| has-lateral lugs 23 which extend into notches 2'4 cut in the bearing portions M ofthe hood. The "relative position of the lugs and notches are such that if the member 20-is rocked counterclock. wise, as viewed in Fig, 3, the lugs 23 will contact the rear side of the notchand cause the-hood member to be swung upwardly. 'As soon as the hoodreaches a vertical positionit swings over and drops by gravity against thecigarettenthe notch being carried ahead of the lugs as is best shown in Fig. '7.

It will be seenv from, a comparison of Figs. 3 and '7 that by this means the motion given to the hood I5 is. much greater than that given to the driving member 20. :This makesit possible to employ a very much simpler operating structture than if the heat responsive member had to go through the entire motion imparted to the hood. A similar action takes place on the re.- verse stroke, where after the lost motion is taken up the lugs 23 engage the member l5 and push it once more to, a vertical position whence it falls over into the full line position. of Fig. 2. i

It was stated above thatrit was desirable to after the cigarette has burned back far enough to uncover the coil IT. The close conformation. of the rest and the hood to the shape of the cigarette causes a sweating action which great 1y speeds up the extinguishing process, making certain that the cigarette will be put out even with a comparatively short dwell of the hood in contact with it.

Various other forms of operating mechanism.

may be used. For instance a metal bellows '30 shown in Fig. 8 may be connected directly to'the .member 20 and filled with a rapidly expansible material. This has the advantage in some cases of producing a straight line action instead of a: rotation as in the case of the-coil;' and of producing a very considerable amount of motion yielding "a substantial degree of power. Another way in' which the device may' be' operated is shown in Fig. 9. A tube 3 I- shaped like the Bourdon tubeused-in a steam gauge is attached to the bracket I6 and passes the notch I 8, then turning back underbeneath the body of the rest. At that point it is connected by a link 32 withthe member 20'. The tube is filled *with a rapidly expansible material; andwhen' the latter is'heated the tube tends to straighten, causing'the operating member 20 to rotate around the pin and throw the hood into active extinguishing position.

"It is not'n'ecessary that the hoodbe confined to a single member at one side which passes entirely over the top of the cigarettel' "As in Figs. 10 to 14 the'hood member may be made in'two sections 35 each pivoted at'36 beside the cigarette rest 32';

A heat responsive member, here shown as abel lowsfl38' simil'ar' to the bellows 30', as secured at one e'ndas to a bracket'39 at oneside of the rest;

and has at its other end a pin Mlbearing collars 4I- positioned to engage an *extension on one of the hoods 35; The hoo'd members have interlocking sections'flyas' shown in 'Figs. 12 and 13, so that they are forced to move simultaneously and in opposite directions. One of the members 35 is provided with 9; lug 43 (Fig. 11)"over which-and over a pin 44 on 't'hebracket39'is' compressed a spring 45; This spring forms atoggle" by which the hood members 'will' be snapped past a dead center position intoeither open or closed relation, as is apparent from "acomparison of Figs.

1'1 and 14." It is'desi rable to have the lost motion connection provided by the collars'M in order to permit the spring to act quickly and to give an additional dwell to' the hood-members in closed position, as has been'discu'ssed above in connection with other forms of" the invention.
