United States Patent() TOBACCO ASH RECEPTACLE Nels H. Nelson, Milford, Iowa Application January 14, 1952, Serial No. 266,403-

1 Claim. (Cl. 131235) This invention relates to smokestands used for receiving tobacco residue such as cigarette butts, cigar butts, and pipe ashes.

Heretofore, most smokestands have a receiving compartment, a hopper portion, and a hand actuated mechanical trapdoor for sealing the receiving compartment against the escape of smoke and odors from the smoldering tobacco deposited therein. The objections to such trapdoors are that they must be manually operated, have smoke-leakage at adjacent parts, are expensive to manufacture, and by being mechanical, often break down in use.

Therefore, the principal object of my invention is to provide a smokestand that has no moving parts, yet is capable of successfully trapping the smoke and odors.

A still further object of this invention is to provide a smokestand or like tobacco ash receptacle that is easily kept in a clean and sanitary condition.

A still further object of my invention is to provide an ash receptacle that rapidly extinguishes a burning cigarette or cigar, once it is deposited in the receptacle.

A still further object of my invention is to provide a smokestand receptacle that is economical in manufacture, attractive in appearance, and durable in use.

My invention consists in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of my smokestand ready for use,

Fig. 2 is an enlarged longitudinal cross-sectional view taken on line 22 of Fig. l, and

Fig. 3 is a cross-sectional view taken on line 3-3 of Fig. 2.

In these drawings I have used the numeral 10 to designate the base portion, which may be of any suitable design. The numeral 11 designates the column or standard. This portion of the device may be of any suitable design, but in the drawing, I show it as an elongated inverted cone. Detachably resting on the top of the standard 11 is the horizontal drum portion 12, having a diameter greater than the diameter of the standard, and with its bottom open to communicate with the top of the standard as shown in Fig. 2. The numeral 13 designates a collar on the bottom of the head or drum 12 that detachably extends into the top of the standard, to.hold and center the portion 12 on top of the standard. The top of the portion 12 extends downward and inwardly to provide a hopper 14. This hopper terminates in an inlet opening communicating with the inside of the standard. The numeral 15. designates an elongated inverted cone container inside the standard and having its bottom closed. This detachable container extends upwardly to near the top of the standard. The numeral 17 designates a vertical post detachably resting in the container as shown in Figs. 2 and 3. This post has a cap 18 and a diameter that is greater than the diameter of the 2,716,414 Patented Aug. 30, 1955 post; The top of this-cap extends downwardly and2.out-

wardly fromits dead center for guiding smokers" refuse:

therefrom andinto thetcontainer between'the wall of tthe container and the post. By-the container being of inverted cone'shape, the lighted-cigarette or? cigar will fall down-' wardly by gravity to wedgevor at least contact one-or in Fig. 2. The :bottom 10f this collar or short tube- 19 terminates above in spaced relation to the center of the top of the cap 18. The'numeral 20 designates a circular flange or battle on the lower outside of the portion 19. This portion 20 extends upwardly and outwardly from the portion 19, but has a diameter less than the inside diameter of the container. The bottom of the drum or head 12 is greater than the maximum horizontal diameter of the hopper portion 14. By this arrangement, the space within the drum head and the space above the flange 20 will be a trap for any fumes, odors or smoke passing upwardly from the container. Cold air will normally pass downwardly through the tube 19, thereby discouraging the upward passage of smoke or odors through the same and into the room in which the smokestand is used. This action is also aided by the cap 18 and the flange ring 20 which serve as baflie elements to guide the smoke and odors away from the bottom of the tube 19. Smoke in movement may go downwardly as well as upwardly and the downward movement of relatively colder air through the tube 19 will aid in drawing upwardly deposited smoke and odors, downwardly with its own movement. Thus, smoke in my device will tend to circulate'therein upwardly and downwardly without escape through the tube 19, until its particles settle in the container. In constructing the smokestand, the diameter of the cap on the top of the post should be greater than the inside diameter of the tube 19.

From the foregoing, it will be seen that I have provided a smokestand free of moving parts. To empty or clean the device, the head drum is lifted upwardly and off, and the container removed. If desired, the post portion may be removed from the container. In order that the post will always be properly centered within the container, I have provided spacing fingers or like 21 as shown in Fig. 3.

Some changes may be made in the construction and arrangement of my tobacco ash receptacle without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim, any modified forms of structure or use of mechanical equivalents which may be reasonably included within its scope.

I claim:

An ash receptacle comprising a base, an inverted frusto-conical receptacle supported on said base having a closed bottom and an open top, a frusto-conical container within the receptacle and having its side wall and bottom in contacting relation with the side and bottom of the receptacle, said container having an open upper end in spaced relation to the upper end of the receptacle, a cover for said receptacle of cylindrical form and provided with a bottom frictionally fitted within the open end of the receptacle, said bottom of said cover having its lower edge in spaced relation to the upper edge of the container, said cover having inwardly and downwardly extending portions defining cigarette rests and a funnel, the base of said funnel having a major portion thereof of cylindrical form and provided at the lower end thereof with a frusto-conical deflector, a post centrally positioned within the container in full surface contact with the bottom of said container, said post being of cylindrical form and of a uniform diameter throughout the length, a conical cap having a base of greater diameter than the base of the post mounted on top of said post, said cap base beingof greater diameter than the base of the funnel, said post being provided with means between its ends adapted to maintain the same in spaced relation relative to the inner surface of the container, whereby burning cigarettes positionedin the cigarette rests with their lit ends above the funnel enable the embers thereof to drop into the funnel to engage the cap and be deflected into the space between the post and the container, and whereby the heated air as a result of these embers will flow upwardly and along the side wall of the container, receptacle and cover and be maintained within those parts so as to effect rapid extinguishing of the embers.
