SMOKERS PIPE w David Homer Hayden, Sarasota, Fla., assignor to- Elinor H. Mayer and Dorothy H. Herald,

of Sarasota, Fla.

both 1 Application October 6, 1945, Serial No. 620,796 4 Claims. (01. 131-197) The main object of my invention is to provide a pipe which will reduce the temperature of the smoke to a degree that will not support nicotine and of a construction that will attract and absorb the sludge and any liquefied nicotine before it reaches the stem of the pipe.

Another object of my invention is to provide a pipe which will give a clean, cool smoke. To effect these results, I provide a construction which includes of course a main outer body bowl and a combustion bowl; The latter is removable and between the two is an intermediate bowl with circulation passages inside and outside of it. In the bottom of the body bowl is a chamber through which the smoke and air are drawn and in which the volatile substances which have not been deposited before reaching this point are condensed and the moisture and sludge collected and from which they may be readily removed.

Fig. l is a vertical sectional view of a pipe embodying my invention.

Fig. 2 is a transverse sectional view on the plane of the line 2-2 of Fig. 1.

Fig. 3 is an exploded side view showing the parts of the pipe.

Fig. 4 is a vertical sectional view of a somewhat modified form of intermediate bowl.

Fig. 5 is a plan view of one half of the bowl of Fig.4. The pipe has a main body or bowl 5 with a stem 6, a combustion receptacle or bowl 1, an intermediate floating bowl 8, agasket 9 and a condensation chamber consisting of a metallic sump i B and a metallic disc I l. The body has an outlet opening or passage 6 extending through the stem and the sump I0 is removably mounted in an opening ill in the bottom of the bowl.

The main body 5 may be made of any suitable hard insulating material such as wood or plastic.

The combustion receptacle 1 is of hard, absorbent but fireproof material such as clay or casein. The gasket 9 may be of any suitable resilient material so that the part 1 can be tightly held in place in the body 5.

The intermediate bowl 8 is formed of molded porous cellular absorbent fireproof material, such as a fibrous moldingsubstance acting as a binder for granulated easily combustible carbon and has ribs l2 on the inside and ribs I3 on the outside so as to leave passages I 2 and I3 inside and outside for the circulation of air and smoke from the outlets It in the bottom of the bowl over the top at I5 to the outlet l6. The intermediate bowl is in loose relation to the other parts, the ribs merely holding it in loose offset relatiOh and giving added absorbent and cooling surface for smoke contact. Shoulders [1 are provided around the lower part of the spacer chamber to hold it offset a predetermined distance from the bowl 1. a

Figs. 4 and 5 show an alternative form of removable bowl 8. serrations are formed in the upper edge adjacent the gasket to form passages 8" beneath the gasket. The chamber i8. between the metal disc I I an the metal pocket or sump It) serves to collect the condensation of moisture and-the sludge from the tobacco. The'smoke is cooled so that little if any of the volatile substance, such as nicotine is carriedover into-the stem. By extending the outlet tube It into this chamber l8 no liquid or sludge is likely to get into the stem. So-much liquid is collected in the sump that it is desirable to empty it after each smoke. It is also desirable to remove the deposit of sludge from the sump ID at least twice during the life of each intermediate bowl 8. The bowl 3 attracts so much nicotine carrying sludge that after its cellular voids become filled all of the smoke passages become choked and when it is removed it resembles a solid body of saturated tarred felt and adheres solidly to thelwalls of the innerbowl'l. Such a condition results from the smoking of about onehalf pound of tobacco, or from one hundred and fifty to two hundred smokes depending upon how tightly the tobacco is packedin the bowl 1. The refill unit consists of the bowls I and 8 and the gasket 9 and when saturated can be removed by pressure against the disc I l. The removal in that manner can only be done while the pipe is warm, otherwise it is necessary to break the bowl 1 and cut out the bowl 8.

This metallic disc H reinforces the bottom of the bowl 8 and when the sump I0 is removed, the bowls 8 and I may be ejected by pressure exerted through the sump opening.

Changes may be made in the details set forth without departure from the scope of the invention as defined in the appended claims.

I claim:

1. A tobacco smoking pipe comprising an outer bowl of hard insulating material, said bowl having a bottom opening leading to the bore thereof, a second bowl nested in said outer bowl and having a bottom surface. said second-named bowl being of cellular absorbent fireproof material, another bowl of hard absorbent fireproof material nested within said cellular bowl, a stem on the outer bowl having an axial passage communicating with the bore and bottom opening of the outer bowl, a removable sump in said bottom opening and metallic disc located on the bottom surface of the second-named bowl for reinforcing said bottom whereby said second and third-named bowls as a unit may be forced outwardly through the top of the bore of the outer bowl by pressure exerted upon said disc through the bottom opening when the sump is removed.

2. A tobacco smoking pipe comprising an outer bowl of hard insulating material with an opening in the bottom end thereof, a stem formed integrally with said bowl and having a passage communicating with the bore thereof, a bowl of porous cellular absorbent fireproof material nested in said outer bowl, ribs on the outer and inner surfaces of said cellular bowl, shoulders on the lower inner surface of said cellular bowl, the ribs on the outer surface engaging the surface of the bore of the outer bowl to provide smoke passages therebetween, another bowl of 'hard absorbent fireproof material nested within said cellular bowl and seated on said shoulders and engagin said inner ribs :to provide smoke passages between said second and third-named bowls, said third-named bowl extending above said other bowls to provide a space therebetween, a gasket in said space for holding the bowls together in fixed relation, a metal disc located on the lower outerrsurface of said cellular bowl, aremovable sumpinathe open- :ing in the bottom of the outer bowl and a tube in the passage in the stem extending .into the opening in the bottom of the outer bowl and above-the sump.

3. A pipe for smoking tobacco comprising an outer bowl having a smoke passage and a "bot- "tomopening, a removable sump in said bottom opening for collecting sludge, a tobacco holding :bowl removablysupported in the outer bowl, and a porous, cellular "fire proof absorbent bowl interposed'between the inner bowl and the outer bowl with smoke passages :between the inner bowl and the cellular absorbent bowl and "between the cellular absorbent bowl and the outer bowl and having a metallic disc-at its lower end above said sump.

4. A tobacco smoking pipe comprising an outer 4 bowl of hard insulating material having an open ing in its bottom end leading to the bore thereof, a removable plug in said opening, a stem formed integrally with said bowl and having a smoke passage communicating with the opening in said bowl, a second bowl removably nested in spaced relationship in said outer bowl and having an imperforate bottom surface, said secondnamed bowl being of molded porous cellular absorbent fire-proof material, a third bowl removably nested in spaced relationship in said second-named bowl and having its lower end formed with perforations communicating with the spaces between the bowls for passage of smoke, said thirdenamed bowl being of hard, fireproof material, and'a metallic disc covering the bottom of the second named bowl and being engageable by a tool through the opening in the bottom end of the outer bowl when the plug is removed whereby the nested bowls may be forced upwardly out of the outer bowl without damage.
