This invention is directed to, and it is an object to .provide, a cigarette extinguisher of novel structure and function.

Anfotherbbject of the invention is to provide .a cigarette extinguisher which is especially designed for use in a motor vehicle. j

, Afurtherobject of the invention is to provide a cigarette extinguisher wherein the cigarettewhen'disposed in a receiver-isextinguished by subjectingthe then inner and burning endoi the cigarette to suction derived from the intake manifold ofthe vehicle engine; therapid reverse "air-flow. throughthe cigarette, from the mouth end to the burning end, causing rapid extinguish- ;ingof said cigarette. N An additional object of the invention is to provide the cigarette extinguisher with a novel valve unit which is normally closed to prevent 1 Claim. Cl. 131-256) cation with the intake manifold 8 of the engine undesirable constant air entry into the intake manifoldof the engine; such valve unit opening underthe'influence of manual projection of the cigarette into the receiver of the device, and the Ci arette then being subject to the reverse airfiow;fas aforesaid;

, A still further object of the invention" is to provide a" practical 'and reliable cigarette extinguisher, and yet one which will be exceedingly eifective for the purpose for which it is designed.

; '1 Still another object of the invention is to providea, cigarette extinguisher which is designed for ease and economy of manufacture.

These objects are accomplished by means 'of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings:

Fig. 1 is a somewhat diagrammatic elevation of the device as in use on a motor vehicle; the

' instrument panel and the fire wall being shown in section.

Fig. 2 is an enlarged sectional elevation of the device in its normal position, with the valve unit closed.

Fig. 3 is a similar view, but shows the device in use, with a cigarette projected into the receiver and with the valve unit open.

Fig. 4 is a cross section on line 44 of Fig. 2.

Fig. 5 is a fragmentary sectional plan of the tubular sleeve unit, showing the parts thereof separated and before being assembled or coupled together with the'stem-mounting cross bar shown in end elevation.

Referring now more particularly to the characters of reference on the drawings, the novel cigarette extinguishing device is indicated gendevice to which the attached.

9; all as clearly shown in Fig. 1. A The cigarette extinguishing device I is show in detail in Figs. 2 to 5, inclusive, and such device comprises the following structure:

The numeral l0 indicates, an inner stationary tubular body coupled at one end with the hose 5; such stationary body beingthe portion of the securing clamp 2 is preferably At the end opposite the hose 5 the stationary tubular body It) is encompassed, in telescopic relation, by an outer slidable tubular body H or sleeve which is slidable on'said body Ill with a relatively close fit.

The tubular body [0, at the end portion within the tubular sleeve II, is of reduced internal diameter whereby to form a longitudinal, reduceddiameter bore l2 and an annular internal valve seat [3. 7

A crossbar M is secured in the tubular sleeve H some distance outwardly of the adjacent end of thetubular body l0, preferably in the following man'nerzThe sleeve II is of metal and is formed as two initially separate alined sections Ila and III); the section Ila engaging the body Ill. The opposite or outer end of section Ha is formed with an internal circumferential recess R, which receives the ends of the cross bar M, as shown in Fig. 4. The other sleeve section llb abuts against the adjacent end of the sleeve section Ha, preventing outward movement of the cross bar, and is formed with a, reduced-size extension E which is press-fitted into the recess R to the sides of the bar I4; this extension being oppositely notched, as at N in Fig. 5, to clear the ends of the bar I4. In this manner the cross bar is rigidly supported against either rotative or axial movement in the sleeve. An axial stem I5 is threaded into such cross bar M. as at l6, and thence extends through the bore l2 in clearing relation with the body I 0 and has a valve head I! having a forwardly tapered face [8 adapted to cooperate with the valve seat I3.

A helical compression spring [9 is disposed in the tubular sleeve section Ha in engagement between the cross bar [4 and the adjacent outer end of the tubular body l0, normally urging said 3 1 tubular sleeve ll outwardly and closing the for wardly tapered face l8 of valve head ll against the valve seat 13.

Thus, normally the described valve unit is closed so that air cannot constantly flow through the device I and hose 5 into the intake manifold 8, which would be undesirable.

When it is desired to extinguish a cigarette the same is manually projected into the exposed or outer end section N6 of the tubular body H, which section is flared, as at 2|, to provide a somewhat funnel-like receiver. The cigarette 20 is projected into such receiver with the burning end 22 foremost, as shown in Fig. 3. 'When such burning end engages the cross bar M, continued thrusting on the cigarette 20 compresses the spring I9 and shifts the slidable tubular body I! inwardly, opening the valve head ll; i. e. clearing the tapered face l8 from valve seat I3. When this occurs a suction imposed air fiow travels through the device, causing a rapid, cold air flow :through the cigarette 20, which together with a reduction in the temperature of the burning end of the cigarette due to direct contact thereof with the metal bar I4, extinguishes the same. Additionally, a slight twist on the cigarette while it .is engaged against the cross bar l5 breaks away strated from actual use that no detrimental effect on the engine is had, since the amount of such ash is very small, and the ash is so fine and nonabrasive that it may be drawn past the intake valves of the engine without danger of damaging or clogging the same.

The described cigarette extinguishing device,

, while being simple in its structure and operation,

is nevertheless most effective to accomplish quick extinguishing of a cigarette with a minimum of manual eifort.

7 It should be noted that the extinguishing operation can be accomplished wholly by one'hand, so

that the driver of the vehicle can maintain the other hand on the steering wheel.

From the foregoing description it will be readily '4 seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:

A cigarette extinguishing device for a motor vehicle comprising a rigid tubular body adapted to be mounted in a fixed position on the vehicle, a conduit connected to the inner end of the body and adapted for connection to a source of suction on the vehicle engine, means in the body at its outer end portion forming a relatively small bore and an annular valve seat facing the inner end of the body, a sleeve sl'idable over the outer end portion of the body, a cross bar in the sleeve outwardly of saidbody, the bore of the sleeve outwardly of the cross bar being in the form of a flaring mouth of a size at the cross bar to receive the lighted end of a cigarette, a stem removably secured in the cross bar and extending thence inwardly through said relatively small bore in clearing relation therewith, a valve head on the inner end of the stem smaller than the bore of the body adapted to engage the annular valve seat, and a spring about the stem between the outer end of the body and the cross bar yieldably holdin the valve seated; said lighted end of the cigarette when pressed against the cross bar sliding the sleeve inwardly to open the valve and enable suction in the conduit and body to act to draw lighted ashes from the cigarette to extinguish the cigarette.
