The object of this invention is to "providea sanitary pipewhich will transmit cool,*dry smoke to the-user-,'devoid-of nicotine and other dele-' terious and disagreeable qualities.

5 A further object is to keep saliva from, the mouth of the smoker from entering the bowl of the pipe and from contacting the tobacco, and

. another and important object is to collect the nicotine in a compartment of the pipe separate from that in which the tobacco is contained and consumed and to provide easy meansfor the removal of the nicotine and for the cleaning of the I D A I accomplish the above by the deviceillustrated in the accompanying drawing, in which:

Fig. 1 is a longitudinal vertical section ofa pipe embodying my invention; M 1

Fig. 2, a like view of the bowl-end of the pipe with the detachable inner bowl removed;-

Fig. 3, a perspective view of the inner bowl tilted to disclose the lower portions; 1

Fig. 4, a cross section on the line 4-4, of Fig.

.1; and

. Fig. 5, a sectional view similar to Fig. 2 of a modified outer bowl.

Like characters of reference indicate like parts in the several views of the drawing. a

The outer bowl 6 may be formed out of wood such as'briarwood, or out of meerschaum, Bakelite or other composition. It has an integral stem extension 1 to whicha mouth-piece 8 is removably attached, preferably and. as shown in Fig.1, by a joint formed by telescoping the re,

5 ducedend 9 of the mouth-piece into a bore ID.

of the extension]. The mouth-piecewill be of any usual and suitable. material.

The outer bowl 6 has the central recess II, which is open atthe top and closed atthe bottom.

) Suspended within the recess II, from the upper edge or rim of the bowl 6, 'is aninner bowl 12, within which the tobacco is placed and burned. The inner bowl I2 has a top outside flange l3 that projects over and rests with a close fit upon the rim of the outer'bowl, as shown in Fig. 1. The outside walls of the inner bowl at M, preferably make a close fit with the bore of the outer bowl adjacent the under side of the flange in order to center the inner bowLbut below, and for the v major length of the inner bowl, the outside diameter is reduced to provide a chamber l5 for the free circulationof heat, smoke and gaseous products of combustion around the inner bowl. This space is continued under the bottom of the bowl [2, as shown, and a hole L6, isformed in ner.

the bottom as the "innerbowl- 'l u for the di char-ge'of-smokeand vaporsw of the bowl 6, forming a communication from the chamber into the bore ll) of the stem-extension 1.- In the form illustrated," the wall of '10 v The flange I3 is made to'conform in shape with the rim of bowl 6, thereby requiring exactitude in itsplacement on the bowl. To insure this and also to draw the flange into a close fit on the pipe Iprovide bayonet joint channels [8, in the inner walls of the recess ll, onboth sides, to receive lugs lfi'formed on the walls M of the inner bowl.

These have oblique channels which act as'a screw thread to draw the flange toward the'rim of the.

bowl, and the channels end with ashortportion 20, parallel with the rim of thebowl and closed to stop the lugs l9 at the rightplace.

In the-operation of my pipe, smoking tobacco upon through mouth-piece 8 in'the usual man The resulting smoke and products of com- 'is placed in the inner bowl l2, lighted and drawn bustion, drawn out through hole l6, circulate all around the inner bowl in the chamber I5 andpass out through'the passageway I! to the bore I0, and mouth-piece}, to the smokers mouth.

. Nicotine and condensed moisture from the tobacco condense and remainat the bottom recess II in theouter bowl 6.

Of thev Q The recess II in the outer bowl'is made acces- 5 sible for cleaning by removing the inner bowl l2.

cloggedor fouled a broom straw or small wire can be pushed through, after. removing the inner bowl and mouthpiece 8. l

In the modification shown. in Fig. 5, the angles of the passageway H are replaced by curves to make the insertion of thewire easier.

While I have here shown and described my in vention in'the best form now known to me, it is obvious that many variations in form and in material out of which it ismade are possible 1. In a pipe having an outer bowl with a central recess, a top rim and a hollowv stem, the .wall of the bowl being thickened 'nextfto the stem and having an inner bowl of less diameter than that Should passageway IT and I bore l0 become of the recess, with a bottom discharge hole and having an outside flange at its top by which flange the inner bowl is suspended in the .outer bowl from the rim of the outer bowl, and said inner bowl having a top spacing ring defining a smoke recess between the bowls, the outer bowl having a smoke passageway in its thickened wall leading from the upper part of the space between the two bowls and discharging into the bottom stem, a bayonet joint comprising a lug on the inner bowl anda channel in the wall of the outer bowl receiving the lug, the entrance of said channel being at right angles to the top of the bowl and leading into a downwardly oblique extension having a convex lower wall terminating with a short portion parallel with the top of the bowl against the end of which short portion the lug is arrested and its return movement resisted by'the convex portion thereby normally locking the lugs.

2. In a pipe having an outer bowl with a central recess, a top rim and a hollow stem,- the wall of v the bowl being thickened next to the stem and having an inner bowl of less diameter thanthat of the recess, with a bottom discharge hole and having an outside flange at its top by which the inner bowl is suspended in the outer bowl and registering in size and shape with the wall of the outer bowl, said inner bowl having a top spacing ring defining a smoke receiving recess between the bowls, the outer bowl having a smoke pasthe lug, the entrance to said channel being at right angles to the top ofthe bowl and leading into a downwardly oblique extension having a convex lower wall terminating with a short portion parallel with the'top of the bowl, against the end i of which short portion the lug is arrested having the return movement resisted by the oblique convex lower wall thereby normally locking the lug,

when the flange of the inner bowl is in register outer bowl.
