TOBACCO PIPE.

Application filed February 6, 1926, Serial No. 86,823, and in France December 12, 1925.

This invention has for its object an improvement in tobacco pipes of all kinds.

' This improvement consists in the application to the shanltof a tobacco pipe, of a special tube for smoke, and secured to the mouth piece, so as to be removable with the latter. This tube at its opposite end terminates in a head forming a rose, opening into the bottom of the bowl, said tube being also formed with a shoulder flange a which closes the shank at one end thereof and provides a nicotine chamber.

This invention is adapted:

First:-To permit cleaning of the nice tine chamber by the flange or shoulder, by removing the mouth piece and the tube which is attached thereto.

Secondr-To ensure complete combustion of the tobacco in the bowl, owing to the rose being placed in the bottom of the bowl and isolating the tobacco.

'lhird:-- lo provide a substantially perfect draft by means of perforations provided in the rose.

Fourth z-To isolate the smoke outlet so that nicotine is prevented from entering the mouth of the user.

Fifth:To prevent clogging due to the simple character of the various smoke passages.

Sixth:To enable the pipe to be readily taken apart and cleaned.

The invention consists of certain features of construction, arrangement and combination of parts as will hereinafter be described and pointed out in the claim reference being had to the drawing forming a part hereof, in which,

Figure 1 a longitudinal section of the tube;

Figure 2 is a longitudinal sectional view of a pipe with the present invention applied thereto.

Referring more particularly to the drawing 0; indicates a head or rose formed on a tube (a. the head being provided with the perforations a for the passage of smoke.

The tube a. and its head a is preferably made of a non-oxidirable metal, such as aluminum, duralumin, etc.

The operation of the device is as follows: Smoke cute the perforations a passes through the a anncl a in tube a and enters the mouth of the smoker, the nicotine settling in the reservoir or chamber (K through the holes a provided in the underside of the tube a.

By unscrewring and removing the mouth piece I), the tube a, which is attached to the mouth piece, is also withdrawn scrapping off and can ving from chamber d all residue, thus cleaning the pipe and its shank.

is, of course, obvious that the form, details, accessories, materials and dimensions may be varied without departing from the principles of the invention.

I claim: r

A tobacco pipe, comprising a bowl provided with a shank having a large bore opening into the bowl, a mouth-piece removably secured to the shank and having a passage smaller than the bore of the shank, a perforated tube of less diameter than the bore of the shank and secured to the mouthpiece, and a tubular perforated head on the for ward end of the tube and having a flange at its inner end, said head extending into the bowl and the flange fitting in the forward end of the bore of the shank and closing the bore and forming the same into a nicotine reservoir.

The foregoing specification of my Inn provement in tobacco pipes signed by me this '19 day of January 1926.

GEORGES GRENIER.
