2 Claims. (Cl. 131256) This invention relates to extinguishers and is herein illustrated in the form of a cigarette extinguisher especially adapted to be incorporated in larger mechanisms or equipment as a low cost element.

Such a device is usually made of standard parts or of parts adapted to be produced by easily adjustable machines, and in a form suitable to be assembled as part of I a larger piece of equipment, such as ash receptacles in cars, trains or theatres.

In the forms herein shown the extinguisher consists principally of a cone to crush and extinguish the glowing end of the cigarette, a cup or funnel-shaped, open-bottomed device within which the cone is depressible so that a normally open member below the funnel or cup is temporarily closed and then is opened to allow ashes to fall into a lower receptacle. A spring tends to return the bottom member to its open position.

To utilize the most easily handled standard form of spring, the return is shown as effected by a coil spring encircling a standard within an outer casing. The casing not only carries elements to guide the standard but also usually carries an extension of some sort to enable it to be readily attached to the larger device.

In the accompanying drawing Fig. 1 shows one form of extinguisher in top view, with the center of the cover partly broken away to show the underlying cone.

Fig. 6 is a sectional view on the broken line 66 of Fig. 5.

In the form of extinguisher shown in Figs. 1 and 2, an extinguishing cone 10 normally lies at or just above the open bottom mouth of a funnel-shaped guide 11, being thrust upward by a coil spring 12.

The spring 12 surrounds a slidable vertical post or standard 13 on which the cone 10 is mounted as a cap, and the spring 12 thrusts downwardly against an abutment 14 which may be a bent piece of spring wire like that seen in Fig. 3, with a central eye 15 serving to guide the post 13.

The free ends of the spring 14 are bent into semicircles 16 which are shown as carried in a horizontal annular bulge 17 formed in the cylindrical casing 18 of the extinguisher body.

The lower end of the post 13 is shown as guided in an identical eye 15 formed in an identical bent piece of wire 14 with identical semi-circular ends 16 lying in a lower bulge 19 in the casing 18.

The parts just described may be assembled by threading into the spring 12, the lower end 20 of the post 13 carrying its soldered on or brazed on cone 10.

Then the post 13 and spring are lowered through the Fig. 4 is a top view of an alternative form of the States Patent open mouth 21 of the funnel 11, the post end 20 passed through the upper eye 15, then through the lower eye 15 so that the end 20 projects through the lower eye 15.

A stop 22, shown as a cap 23, is attached to the lower end 20 of the post, and the moving parts of the extinguisher are complete.

In the form shown, a lower part or extension of the funnel 11 is shown as a peripheral bulge 24. Within this the cone 10 moves up and down, going down through a short nearly cylindrical portion 25 below the bulge 24, until the bottom edge of the cone is arrested by an inner ledge 26 adjacent and above the top of the bulge 17.

The wire guides 14 permit the ashes on the cone 10 to fall freely into a receiver 27 shown as a separate cup 28, adapted to be attached to the cylindrical casing 18 by joints 29 shown diagrammatically as opposite bayonet joints on the lower periphery 30 of the casing 18.

Often the cup 28 will carry a thin layer of lead or solder 31 within its bottom for stability.

The casing 18 usually carries a projecting loop 32 for attaching the extinguisher to a support, such as part of the dash board of an automobile.

This may take the form of a bracket 33 attached as by a rivet 34 at the bulge 24, fitting the downward curve 35.

Thus the curve of the bulge 24 straddles the bracket 33 and leaves the top 36 free to hold a cover 37 for the funnel, preferably hinged at the opposite side at 38, and provided with a holding resilient tongue 39.

The alternative form of extinguisher shown in Figs. 4, 5 and 6 is especially adapted to be largely made by metal die-casting to simplify assembling operations.

In these figures the specially shaped extinguishing cone 40 is shown as carried on the upper end of a slidable post 41, either welded or riveted thereto, or cast as a unit therewith, and as guided in its sliding by the central bore 42 in a long internal lug 43 which projects part way across the base of the housing 44.

The housing 44 is shown as cast integral with the lug 43 and also integral with a funnel-shaped top 45 within which the post on the cone 40 slides.

The housing 44 may also carry an integral fastening device such as the side plate 46 provided with a bore or bores 47 adapted to receive hooks or screws to hold securely the extinguisher in a convenient spot.

The slidable post 41 is shown as normally upheld by a coil spring 48 surrounding it and put on it before the device is assembled, so that the spring 48 strikes the upper face 49 of the lug 43 and thus lifts the cone 40.

Then a stop 50 such as a wedged-on washer is forced on or threaded on at the lower end of the post 42 to limit its throw by striking the lower face 51 of the lug 43.

The cone 40 normally stands nearly half way up the slanting part of the funnel 45 with its lower edge 52 clear of the slanting funnel wall 53. As the cone 40 descends it enters a fairly close fitting cylindrical length 54 of the casing 44 and finally comes to rest on the internal flanged bottom 55 of the cylinder 54 where it merges into the lower cylindrical body 44.

The lower edge 52 of the cone 40 is shown with peripheral outwardly and upwardly turned teeth 56 which hold the impinging cigarette from slipping into the opening around the cone '40 but permit ashes to pass.

The lug 43 preferably leaves open a large area of the casing 44, so that ashes fall readily into a bottom container 58 diagrammatically shown as held by bayonet joints 59 on the casing 44.

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

l. A cigarette extinguisher including a slidable cone against which a lighted cigarette may be pressed, a funnelshaped casing surrounding the cone, a bottom forming part of the cone, an internal annular ridge Within said casing adapted to arrest said cone when its bottom reaches the ridge, means whereby the cone is supported and guided, a return spring forming part of said support means and normally holding the cone clear of the funnel bottom, and teeth at the bottom of the cone extending upwardly and outwardly to hold a cigarette against sliding ofi the cone.

2. A cigarette extinguisher including a slidable cone against which a lighted cigarette may be pressed, a funnelshaped casing surrounding the cone, said cone having a bottom, an internal annular ridge Within said casing adapted to arrest said cone when its bottom reaches the ridge, a return spring normally holding the cone clear of the funnel bottom, teeth at the bottom of the cone extending upwardly and outwardly to hold a cigarette against sliding ofi the cone, 2. post beneath the cone on which the cone is carried, a guide for the post, said spring thrusting 5 against the guide to support the cone.
