Claims. (Cl. 131-195) This invention relates to new and useful improvements in smoking articles and has especial reference to pipes and cigar and cigarette holders.

An object is to provide a simple and eicient construction whereby the pipe or dev ice is thoroughly cooled and the smoke is also thoroughly cooled before it reaches the mouth of the smoker.

A still further object is to provide a simple and efcient device whereby the saliva is trapped effectively away from the mouth of the smoker.

Yet another object is to provide a simple and eicient device by means of which the various partscan be quickly and easily taken apart in a few seconds for repair, cleaning, or replacement. Still another object is to provide a simple and efficient device wherein the smoke travels perforceV a very circuitous path so that it is cooled effectively before it reaches the mouth of the smoker and the contained liquids are forced to be deposited therefrom before the smoke arrives at the mouth.

Further and more specific objects, features, and advantagages will more clearly appear from the detailed specification hereinafter set forth especially when taken in connection with the accompanying drawings which illustrate several forms which the invention may assume and which form part of the specification.

In brief and general terms the invention inf cludes a plug in one end of the hollow stem provided with upper and lower passages therethrough for the saliva passing through the lower passage and the smoke passing through the upper passage.

Further the invention comprises a plug, a hollow tube extending therefrom to the other end of the stem and opening at each end to the atmosphere whereby the interior of the pipe is subjected to the action of cooling outside air at all times with baie members disposed along the tube and provided with structure forcing the smoke to travel a circuitous path to move from one end to the other.

Yet further the invention includes a special form of bailie member on a supporting rod or tube within the stem which has an annular peripheral groove forming thin contact rims for engagement with the stem to reduce passage of heat thereto and provide a circuitous path for the smoke together with axial passages in the rims offset from each other to further this circuitous passage of the smoke.

The present preferred forms which the inven- 2 tion may assume are shown in the drawings, of which:

Fig. 1 is a vertical longitudinal section through the preferred form of the device;

Fig. 2 is an enlarged cross section of the left hand portion of a removable member shown in Fig. 1;

Fig. 3 is a transverse section thereof on the line 3 3 of Fig. 2;

Fig. 4 is a vertical longitudinal section through a modification of the device shown in Fig. 1; and

Fig. 5 is a cross section showing the modified parts in an operative position, wherein a, cigarette is ejected.

In the preferred form ofthe invention shown in Fig. 1 the invention is adapted for the use of a tobacco pipe and comprises a hollow pipe stem I0 into the wall of which near one end is screwed a pipe bowl II. A circular block or plug I2 frictionally ts into the'end of the stem I0 and has a shoulder I3 to limit the inward movement of the plug into the stem. The outer portion of the plug which extends beyond the end of the stem I0 is of the same diameter as the stem to make a smooth even surface and meeting edge.l

The plug is provided with an outer axial chamber I4 to frictionally receive the bit I5 of the pipe which has a bore I6 therein leading to the chamber I4. The plug has upper and lower passages I1 and Il respectively therein, the upper passage being shown in Fig. 1 which connects the chamber III with the interior of the stem I0. Through the lower passage Il the saliva from the mouth of the smoker will pass into the interior of the stem I0 whereas through the upper passage I'I the smoke will pass from the interior of the stem I0 to the chamber I4 and thence out through the bit I5 into the mouth of the smoker.

Extending centrally from the rear face of the plug or block I2 and concentric With the stem Ill, is a cooling air tube I8 which may be connected to the plug by being formed integrally therewith or in any other suitable manner. The other end of this tube I8 is screwed into the aperture I9 at the other end of the stem I0. The

plug I2 is provided with a lateral passage 20 extending from the one end of the tube I8 to the outer surface of the plug whereby cooling air may pass from the atmosphere at one end of the stem Il) through the tube I8 and out the lateral passage 20 to the atmosphere again.

In order to make the smoke pass in a long circuitous path from the Ybowl II to the bit I5 I have provided a series of separate chambersl along the stem in which the liquids in the smoke may having respective longitudinal passages disposed therein at angularly opposite points, and said rims making contact with the inner wall of the stem along their circumferential areas.

5. In a smoking article having a stem, the combination of a hollow concentric element mounted within the stem with a plurality of spaced bale discs fitted on the element, said element being open at opposite ends to the atmosphere, said discs each having an annular peripheral groove 10 forming spaced rims making a passage for the smoke, said rims having respective longitudinal passages disposed therein at angularly opposite points, and said rims making contact with the REFERENCES CITED The following references are of record in the ille of this patent:
