August-63, 1943i This application February 271, 1945,V Serial No. 579,928 Y c1aims.,v (c1. 1351-237) able for4 extinguishing cigaretes and is hereiny described in some detail. asi embodied in, a molded' plastic box having a top. to close in, anyl smolderng cigarettey left therein. This application is a continuationv of my priorA application Ser. No.`497,5'14, led August 6 1943.

Cigarette` extinguishers are already known which embody a cone against which the tip of a burning cigarette may be pressed to extinguish the glowing'tip.

Suchan extinguisher may be perfectly satisfactory when so used, but the extinguisher: is' unsatisfactory when built into the cover of a box intended to hold cigarette stubs for the reason that the opening around the extinguishing cone permits cigarette smoke to escape as it rises from any unextinguished stubs deposited within the box.

For that, and other reasons, it is desirable to provide a cigarette extinguisher which will easily be built, rugged, obviously simple to use effectively, and which automatically closes any opening in the structure upon which it is mounted.

According to the present invention, a cigarette extinguisher is provided which avoids all the disadvantages and objections mentioned above and meets all the enumerated requirements. The extinguisher shown is well adapted to be molded out of many synthetic plastics,k either as part of a box or as an element adapted to be sold separately to assemblers who vcombine the element with boxes or other supporting devices.

Other features and advantages will hereinafter appear. f

In the accompanying drawing,

Figure 1 is a sectional view of an extinguishing unit mounted in a separate box cover.

Figure 2 is a bottom view on the line 2--2 of Figure 1.

Figure 3 is a fragmentary view in section on the line 3-3 of Figure 1, showing the extinguisher in the act of extinguishing a cigarette.

Figure Y4 shows the parts of Figure 3 at the end of an extinguish act.

Figure 5 shows they principal operating vparts spaced for clarity of illustration.

Figure 6 shows the extinguisher as a molded-in part of a box cover.

In the form of the invention shown in Fig. 1, a cigarette I0 witha glowing tip II is being lowered to be extinguished, but is shown just as it touches the extinguishing cone or floating plug I2. As the cigarette III is pushed down further the tip Il is pressed against the cone I2 and 2 disintegratesy or: yields while;v the,r cone; is down against the compressions. of' its, spring; I3 whichrests upon a cross-.piece HlV extending across the bore I5lof the shell IE. until; the cone lf2-.is-4

- arrested by the closing of thee coils` of; its. spring.

The cigarette a'shesa may fall down around. the

coney within the cylinder; Atthe: same time,thea body of the cigarette IB hasicomeV in contactwith the c1o'se`iitting funriel-sliaped` inside face I1 of a slidable hollowsleeve; lzwhichtszfairly closely; within: the shell I6, and. is thrust: upwardly` bya decidedly strongerr spring; I9; also bearing; uponthefcross-piece I4..

When thecigarette I0 is pressed further down-y wardly, toward the Figure 4 position,`it pushes down the sleeve I8, pinching the tip II between the funnel-shaped face I1 and the cone I2, and completely extinguishing it.

Upon withdrawing the extinguished cigarette the spring I moves the sleeve I8 upward, as it is guided by its legs 20 which lie on each side of the opening 2| which straddle the cross-piece I4, moving it until the sleeve I8 is stopped by the pin 22 projecting from the side opening 23. The metal pin 22 stops its upward movement because it reaches the upper end of the guide slot 24 in the shell I5'.

While the sleeve I8 moves up, the cone I2 is following it under the urging of its lighter spring I3. The cone I2 is confined by lower skirt 25 of the funnel-shaped face I1, because its flat annular rim 26 lies against the annular lower edge of the skirt 25.

The skirt 25 is shown as spaced away from the outer wall of the sleeve I8 forming an annular pocket in which lies the upper coil of the spring I9.

The outer surface of funnelfshaped face I1 is shown as forming an annular boss 21 which suggests to a user that the cigarette be not pushed too hard, because the boss 21 seems to strike the top of the shell I5 to limit its motion.

In Figs. 1 and 3 the shell I6 is shown as closely fitted by a press iit into an opening 28 in the rabbeted top 29 of a box or

receptacle having sides

30, 3|. The shell I6 may be provided with an annular boss 32 to serve as ornament and to prevent the shell I6 from being pushed down through the top 29. The shell I6 with itsboss 21 forms a convenient handle for lifting the top 29 to deposit cigarette stubs therein, and the top 29 and shell I8 and cone I2 close the box against escape of smoke if any unextinguished cigarettes are placed in it, while the depressed pushed.

cone I2 allows ash to drop into the box, around the cross-piece I4.

The cone is shown as guided by a downwardly projecting post 33 passing through an opening 34 in the cross-piece I4, which may carry a boss 35 around the opening 34 to steady the post 33.

The structure shown in Fig. 6, includes the cone I1, the hollow cylinder I8, but the sleevev I8 slides in an opening 36, in a cover 31 hinged at 38 at the top of one side 39. The rabbeted cover 31 is shown as molded with an integral boss 21 forms a convenient handle for tilting the cover 31 on its hinges 38. When the cover 31 is down, the cone I2 closes the hollow cylinder I8, and no smoke can escape.

The molded parts of either form are easily assembled and then the pin 22 inserted to hold the structure together.

Having thus described in some detail certain embodiments of the invention, what is claimed is:

1. In an extinguisher a support, a slidable hollow sleeve adapted to have a cigarette fit within it, a slidably mounted plug within the sleeve adapted to be struck by the tip of the cigarette and be pushed by it before the sleeve is pushed, springs on the support tending to return the sleeve and plug to close them together 4 against passage of smoke, and a receptacle beneath the support.

2. In an extinguisher having a support, a sleeve slidable in the support, a skirt inside the sleeve, a plug adapted to lie against the underside of the skirt, springs for the sleeve and the plug thrusting them upward, and a pin limiting the travel of the sleeve in the support.

3. In an extinguisher, a box, a top for the box, a hollow sleeve slidable on the top to receive a cigarette tip, a plug normally closing the sleeve but moved by a cigarette tip to open the sleeve to permit ashes to fall into the box, a spring for the plug, and a stronger spring for the sleeve.

4. In an extinguisher, a box, a top for the box, a hollow sleeve projecting above the top and slidable in the top to receive a cigarette tip, a plug normally closing the sleeve, but moved by the cigarette tip to open the sleeve to permit ashes to fall into the box, a cross-piece below the sleeve, and springs resting on the cross-piece separately supporting the plug and sleeve.

5. In an extinguisher a support, a hollow sleeve slidable in the support, a funnel-shaped skirt within the sleeve, a slidably mounted plug within the sleeve, an annular rim on the plug adapted to underlie the skirt, a spring normally holding the plug against the skirt, a stronger spring holding the sleeve so that a cigarette rst depresses the plug to open a passage for ashes and then depresses the sleeve to pinch the cigarette tip against the plug, and a stop limiting the throw of the sleeve.
