Tobacco pipe

The invention relates to a tobacco pipe with a detachably arranged chamber on the front for cleaning and cooling the smoke.

A tobacco pipe built for this purpose has already become known, but it is still has disadvantages insofar as those arranged in the interior of a removable housing Channels, which are extremely fine tubes, cannot be reached for the purpose of cleaning and which are themselves the entire interior of the housing can easily fill with residue and then become unusable. Aside from that· the case attached to the front of the pipe head has an unsightly shape and gives the entire tobacco pipe an unfamiliar look.

Other attempts also aimed at using cylindrical filter bodies Chamber body, etc. the task set, the path of the smoke through appropriate guidance of the To extend the smoke duct in order to cool the smoke and eliminate harmful components of the smoke by condensation or the like, but this does not result in a complete solution led. Here, too, are the bodies used and the resulting spaces for the purpose of cleaning difficult to reach and tend to clog the smoke paths created.

To eliminate these disadvantages and a solution to the problem, a perfectly dry and Cool tobacco pipe to be smoked with a detachable chamber for cleaning on the front and to achieve cooling of the smoke, according to the invention, the cleaning device consists of one Chamber body which can be pushed in in the axial direction of the head or can be folded down from it is formed, which, tightly fitting against an end wall of the combustion chamber, against these open smoke channels

has, on the one hand through the end wall in connection with the combustion chamber and are in connection with the main smoke duct after the smoke has been deflected several times. the Smoke channels are expediently in the chamber body from the inlet opening from the combustion chamber One branch raised, branched up on both sides and parallel to the first branch downwards guided and united under the inlet opening,

ίο where the exit of the Smoke takes place in the main smoke duct. Furthermore, the end wall is designed in the shape of a disk and is used in the guide grooves of the pipe head es_, and it can be between the chamber body

and the end wall a disc of asbestos or other filter material provided with smoke passages be detachably arranged.

The subject of the invention is shown in the drawing. shown somewhat enlarged as an example. It shows

Tobacco pipe coming main smoke channel α goes under the tobacco floor through to the chamber body b and opens into this at c. The chamber body b has the so-called smoke channels d and e and finally has a connection with the combustion chamber g through the short channel f. Disk-shaped asbestos or other filter materials i are preferably also inserted between the chamber body b and the disk-shaped wall h which closes it off with respect to the combustion chamber g.

Bowl and chamber body may be made of any suitable materials for smoking pipes, whereas the terminating wall h for example of aluminum or may consist of another metal, is thus easy to replace, if necessary. shape

and execution of the pipe head as well as other parts of the tobacco pipe can be arbitrary, since these have no influence on the invention.

When smoking, i.e. when the smoker draws the smoke, the smoke goes out of the combustion

Chamber g first in the short channel / in the smoke channel e up to the top, there this channel divides into the two downward smoke channel branches d. The filter material i will at least partially fit into these smoke channels and, in addition to the task of insulating the end wall h, also filters the smoke. At c , the smoke channels d reunite, and the smoke now reaches the smoker's mouth via the long main smoke channel α. The chamber body b is preferably held in a dovetail shape in the bowl of the pipe. However, other types of fastening of the foldable chamber body are also possible.
With this tobacco pipe it is achieved that the smoke reaches the smoker completely dry, filtered and cooled, which is possible with the so-called dry back smoking device shown and described, and these properties achieved according to the invention are justified as follows: Below the tobacco base, the main smoke channel opens into the rear chamber, which is insulated against heat, whereby the smoke cools, its bad nicotine-containing substances are deposited, which can be increased by the use of known chemicals. In this way, the smoke reaches the main smoke duct. Moisture can therefore not get into the pipe bowl or into the tobacco. This results in economical smoking. The exchange of the filter for cleaning, renewal or the like can be done when the pipe is burning, since all smoke channels are exposed when the closure to the chamber body is opened.
