TOBACCO PIPE.

Application filed June 21,

This invention relates to tobacco pipes and aims for its principal object to provide an improved means for effecting the absorption and drying up of moisture which ordinarily collects in the bottom of the bowl and which means at the same time serves to minimize heating and the possibility of cracking the bottom of the bowl, whereby cool smoking and a dry pipe is obtained.

The invention furthermore comprehends an improvement in tobacco pipes which is of an extremely simple nature, which does not materially increase the cost of production and which is highly efficient in its purose.

P With the above recited and other objects in View, reference ishad to the following specification and accompanying. drawings in which there is exhibited one example or em bodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the sco eof said claims may be resorted to when ound expedient.

In the drawings- Figure 1 is a side View of a tobacco pipe with parts in section and illustrating the same constructed in accordance with the invention;

Figure 2 is a fragmentary bottom plan view of the bowl portion of the pipe;

Figure 3 is a transverse sectionalg view through the bowl of the pipe taken approximately on the line indicated at 33 of Figure 1 v Figiire t is a collective perspective view of the absorbent element and its cover in juxtaposition.

Reterring to the drawings by characters of reference, 10 designates a pipe bowl having a stem portion 11 which communicates with the bowl through the usual smoke passage 12. The bottom of the bowl is recessed at 13, which recess is preferably of circular formation, to receive an annular or ring shaped absorbent element 14, constructed of meerschaum, or any other suitable absorbent material. The absorbent element 14 is prefer- 1926. Serial No. 117,515.

ably covered by a metal disc 15 which defines with the bore of the'element 14, a compartment 16.

In order to admit ofa free air circulation to the compartment 16 for the purpose of drying moisture absorbed by the absorbent element and for cooling the metal disc and the bottom of the bowl, registering air passages or

apertures

17 and 18 are formed in the element 14 and in the bowl while an additional air passage 19 is provided in the bottom of the bowl to directly communicate with the interior of the element 14.

In practice, the saliva or other moisture which collects in the bottom of the bowl will be absorbed by the element 14 and the air circulating through the

passages

17, 18 and 19 will serve to dry up the moisture thus absorbed and at the same time maintain the disc 15, the element 14 and the bottom portion of the bowl in a cool condition.

It is of course understood that the draft passes through the pipe bowl and the smoke passage 12 in the usual manner and that the

passages

17, 18, and 19 do not communicate with the inside of the bowl proper.

What I claim is:

1. In a tobacco pipe, means for absorbing the moisture which collects at the bottom of the bowl and means for affording air cirs0 culation to the interior of the moisture-absorbing means, independent of the draft circulation through the pipe.

2. In a tobacco pipe having aircirculation apertures in the bottom of the bowl, a ring shaped absorbent element arranged in the bottom of the bowl having air circulating apertures registering with the first mentioned apertures and a cover member closin g the upper end of the ring shaped element for preventing communication between the air circulation passages and the interior of the bowl.

3. A tobacco pipe including a bowl having 7 a recess in its lower end and provided with air circulation apertures communicating with the recess, an absorbent element snugly fitting within the recess closed at its upper end, and provided with apertures registering with the first mentioned apertures whereby the free air circulation is provided to the interior of the absorbent element.

4. A tobacco pipe including a bowl having a circular recess in its lower end, an 5 annular absorbent element snugly fitted in the recess and closed at its upper end, and registering apertures in the pipe bowl and the absorbent element for maintaining an air circulation in the interior of said ab sorbent element whereby to dry up the nnxture absorbed by the absorbent element and to cool the bottom of the bowl.
