1 Claim.

This invention relates to improvements in tobacco pipes and has for its object a simple and efficient construction of the pipe and particularly of the bowl portion.

It is another object of the invention to provide a pipe which will produce a dry and pleasant smoke.

It is a further object of the invention to provide a tobacco pipe which is provided with a heating chamber in its bowl the heating chamber serving to evaporate moisture, nicotine and the like which usually collect at the bottom of the bowl.

It is still an object of the invention to provide the bowl of a tobacco pipe with a removable plug consisting of a heat conducting material which has a large heat capacity.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, and illustrated in the accompanying drawing in which:

Fig. l is a longitudinal section through one form of my improved pipe, and

Fig. 2 is a similar section through another form of my improved pipe.

Generally, it has been the aim of previous inventors to dry the smoke of a tobacco pipe. Frequently, for this purpose cooling chambers or the like of various construction have been provided in the bowl of the pipe. Such cooling chambers also have the purpose to collect nicotine, moisture and the like and by removing the collected moisture from time to time it was thought possible to produce a cool smoke which did not contain moisture to a substantial extent. However, by using a customary tobacco pipe the smoke can not really be cooled down and the moisture collected in the bowl of the pipe has a tendency to run down the stem into the mouthpiece of the pipe which is extremely unpleasant.

My improved tobacco pipe is provided with a heating chamber which, contrary to the heretofore accepted ideas, heats the lower part of the bowl. Accordingly, all the moisture which collects at the bottom of the bowl is evaporated and leaves together with a part of the tobacco smoke at the top of the bowl. Also, the moisture which may run down from the mouth of the smoker into the mouthpiece and thence into the bowl is also evaporated as soon as the same enters the bowl. Therefore, it will be seen that the tobacco is always kept dry and the resulting smoke will be dry and very pleasant.

Referring more particularly to the drawing, I is a tobacco pipe provided with a bowl 6 and a stem 8. The bottom of the bowl is provided with an opening 3 which is closed by a plug 2 which may preferably be screwed in as shown in the drawing to facilitate the removal of the plug which may be desired in order to clean the pipe. Plug 2 consists of a heat conducting material and the same must also have a large heatcapacity. Ac-

cordingly, plug 2 may, e. g., consist of aluminum or its alloys, aluminum having a large heat capacity and also being a good conductor of electricity as well as of heat. However, any other suitable material particularly any metal which fulfills the above conditions may be used.

7 As shown in Fig. 1 plug 2 may have a plane surface 4 or plug 2 may be provided with an inwardly curved surface or cavity 1 to facilitate the collecting of the moisture on top of the plug. As shown in the drawing plug 2 protrudes a certain distance'into the interior of the bowl.

The construction of stem 8 does not form part of my invention and it will be understood that any suitable stem may be used in connection with my improved bowl.

In use, the burning tobacco will soon heat plug 2 to an elevated temperature. The large heat capacity of the plug is essential because once the plug is hot it holds the heat a considerable time. The moisture and nicotine which is always formed in a tobacco bowl when the same is used will collect on top of plug 2 where the same will evaporate and escape through the top of the bowl.

Thus, it will be readily seen that a dry and clean smoke will be obtained.

The heat storing property of plug 2 has still another function. It has been found that a pipe provided with my improved bowl construction does not go out so easy as other pipes. The heat from the bottom of the bowl keeps the tobacco dry and also helps to keep the tobacco hot.

I claim:

A tobacco pipe comprising a bowl, a stem connected with said bowl and having a smoke passage connecting with the interior of the bowl, the bowl having an opening in the bottom thereof of appreciably less diameter than the tobacco-receiving space of the bowl, a plug removably secured in said opening, said plug being of material which readily accumulates heat and having a portion which extends into the tobacco-receiving space of the bowl, the top of said portion being recessed to form a cavity for the collection of condensed products of combustion, said portion terminating below the level of the passage connecting the interior of the bowl with the smoke passage of the stem and being appreciably smaller than the diameter of the tobacco-receiving space of the bowl to form an annular space below the level of said passage and between said portion of the plug and the wall of the bowl, whereby the upper and side faces of said portion of the plug will be contacted by the body of burning tobacco and heat accumulated in said plug body to facilitate evaporation of the condensed products of combustion within the bowl.
