GEORGES GBENIER, OF ST. CLAUDE, FRANCE.

TOBACCO PIPE.

Application filed February 8,1926, Serial No. 86,887, and in France December 11 1925.

This invention has for its object an improvement in tobacco-pipes in general.

This improvement is characterized by the application in the shank of the tobacco pipe 0 an apertured tube presenting, at the rear of the bowl of this pipe, an obturating flange,

towards the middle of its length, a central separating partition and, on the side of the mouth-piece, an outer shoulder and a screw-- s threaded sleeve screwing in this mouth-piece. The end of the tube, on the .side of the pipe bowl, enters in the bottom of this bowl,

the flange closes a nicotine reservoir surrounding the tube the partition separates is the two parts of the apertured tube, whilst the screw-threaded portion renders this tube ri id with the mouth-piece.

e smoke from the bowl enters the tube through the corresponding apertures, passes as in this tube under the flange, issues through other apertures for entering the nicotine reservoir and passing over. the partition-of this tube, passes again in the same tube through .the apertures and enters in the at mouth at the smoker through the mouthpiece;

The advantages of this system are the tolluwing:

It: lDry tobacco owing to its absolute iso lation hom any moisture coming from smokers mouth, this isolation being obtained owing to the flange and to the central partition forming an obstruction to any salivation.

2": Perfect drawing owing to wide apertures formed in thetube. I 3": Fresh and SWBBtSIIke' owing to the circulation of the smoke and to its condensation in the nicotine reservoir which at surrounds it, I V

t1Noniuicy pipe, ,as the bottom of the bowl is sheltered from any salivation. 5: Absolutely unobstructable pipe owing to the perfect constructionof the system.

6: Automatic cleaning of the nicotine reservoir by the simple removal of the mouth-piece, owing to the flange which scrapes this reservoir.

of example, this invention will Biy wa at be escri ed hereinafter with reference to the accompanying drawing in which:

Fig. 1 shows in longitudinal section thetube permitting the realization of this invention. v a

Fig. 2 is a cross section of the same tube made according to line A-A of Fig. 1

' Fig. 3 shows the said tube in use.

As' il1ustrated in the drawing, the tube a of this invention is apertured as a lantern. Moreover, it is provided with a flange a a central separating partition a and an outer shoulder a in front of a screw-threaded ortion a.

he first apertures a of the tube correspond to the bowl 6 of the pipe and enter in t 1e bottom of this bowl; the flan e a closes the nicotine reservoir .0 provi ed in the shank of the pipe concentrically with the tube; the shoulder a bears against the edge of the mouthiece d andthe screw-threaded portion a o the tube is screwed in the mouth-piece, so that the tube a and the mouth-piece dare thus rendered rigid together.

The suction of the smoke is eifected in the bottom of the bowl 6 throu h the first corresponding apertures a. oft e tube a. This smoke goes through the tube by passing under the obturating flange 0 issues throu h the middle apertures a, passes in the nicotine reservoir 0, escapes tram this reservoir to seeing over the obtureting partit-ion w of t is tube, comes baclr in the tube by passing through the last apertures a and finall circulates in the sleeve a of the tube a an in the mouthiece d for entering the mouth of the smoker, as shown by the arrows.

During its assage in the nicotine reservoir c the smo e is purified and cooled.

By removing the mouth-piece d, the tube a is withdrawn with the latter and the flange a of this tube scrapes all the impurities contained in the nicotme reservoir 0, impurities which are from this fact evacuated outside.

The central tube a is preferably made of duralumin so as to be non-oxidizable, but it might be also made of bone, ebonite, etc.

It will be'fitted in any manner whatever to the mouth-piece of the pipe, this mouthpiece might also have any shape.

The suction apertures can be replaced by a variable number of holes and the end of the tube in the bottom ofthe bowl I) might be of any arrangement and have any suitable shape for ensuring the suction.

I claim:

A tobacco pipe comprising a bowl, a shank having a bore of equal diameter throughout, a mouth piece secured in the shank and a tube in the shank and extendin into the bowl in engagement with the wal thereof, said tube having its outer end screw the bowl and shank the tube being provided threaded and screwing into the mouth piece, with longitudinal slots between the shoulder 1 a shoulder abutting against the mouth piece, and artition, the partition and flange and a partition s aced from the shoulder, and a the an e and the end of the tube.

flange s aoe from the partition and the The oregoin specification of my iminner an of the tube, said flange lying in the provement in to acco pipes signed by me here ofthe shank' at its entrance into the this 19 day of J anuar 1926. bowl and closing communication between GEO GES GRENIER.
