1 Claim. (Cl. 131-203) The present invention relates to a smoking pipe.

It is an object of the present invention to provide a smoking pipe characterized by the inclusion of an absorbent cartridge design to absorb saliva without interferring with the passage of smoke through the pipe.

More specifically, it is an object of the present invention to provide a pipe having a continuous passage from the bowl through the stem, a chamber or receptacle at one side of the passage adapted to receive a cartridge, a generally tubular cartridge in the receptacle closed at one end and having its other end open and in communication with the passage through the stem.

It is a further object of the present invention to provide a smoking pipe of the character described including a removable tobacco shield adapted to be inserted in the top of the passage leading from the bottom of the bowl through the stem.

Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a longitudinal elevational section of the smoking pipe.

Figure 2 is a section on the line 22, Figure 1.

The pipe comprises a bowl which may if desired be provided with a liner 12 formed of clay or other suitable material. The bowl 10 includes a lateral extension 14 having an enlarged recess 16 at one end designed to receive the reduced end portion 17 of the pipe stem 18.

The main portion of the bowl 10 is provided with a downwardly extending relatively large passage 20 which communicates directly with one end of a relatively large cylindrical chamber or receptacle 22 which extends through the laterally extending portion of the bowl. Extending along the upper side of the cylindrical chamber or receptacle 22 is a relatively small smoke passage 24 which also extends completely to the end of the lateral extension 14 of the bowl.

The stem 18 is provided with a passage 26 extending completely therethrough. Between the ends of the reduced inner portion 17 of the stem there is provided a laterally extending passage 28 which communicates with the smoke passage 24 extending longitudinally of the laterally extending portion of the bowl.

Within the chamber or receptacle 22 there is provided an absorbent cartridge 30 which is of generally tubular form having a central longitudially extending passage 32. At one end the passage 32 is closed by a transverse wall 34. The other end of the passage 32 is in alignment with and in direct communication with the passage 26 which extends longitudinally through the stem.

In order to prevent clogging of the relatively small smoke passages through the bowl, its lateral extension, and the stem, there is provided a tobacco shield 36 which includes a circular portion provided with downwardly extending, preferably resilient, legs 38 adapted to be received in the upper portion of the relatively large passage 20. Preferably, the legs 38 or the circular portion 36 are provided with abutment elements 40 which retain the circular portion 36 above the top of the passage 20 and accordingly provide openings 42 through which the smoke may be drawn.

With the foregoing construction it will be apparent that the passage for smoke from the bowl is through the openings 42 into the passage 20 and thence longitudinally through the passage 24. From this passage the smoke passes through the short lateral passage 28 to the passage 26 extending through the stem.

At the same time, it will be observed that saliva entering the passage 26 will not enter the upwardly extending passage 28 but instead will enter the space between the adjacent end of the cartridge 30 or into the internal passage 32 in the cartridge. The cartridge is thus capable of extremely efficient absorption of moisture and/ or liquid since both its internal and external surfaces are eifective for this purpose. The cartridge 30 is of course readily removable for replacement. A preferred form of cartridge is produced from absorbent paper rolled into the form illustrated and provided with means closing one end of the central opening. Alternatively, the cartridge may be formed of absorbent fibers or other material which are not initially produced in sheet form but which are shaped into the cartridge form illustrated. It is desired to emphasize the advantages of the cartridge which result from its provision in tubular form having an open end so as to receive moisture at both its inner and outer surfaces for maximum efficiency.

The drawings and the foregoing specification constitute a description of the improved smoking pipe in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claim.

What I claim as my invention is:

A smoking pipe comprising a bowl having a tobacco receiving portion and an extension extending laterally outwardly from said tobacco receiving portion, said extension having an elongated generally cylindrical chamber extending lengthwise therewithin and communicating with the tobacco receiving portion, said chamber being open at the outer end of said extension, an elongated cylindrical moisture-absorbent cartridge received and closely confined within said chamber and having a central longitudinally extending through passage, the inner end of said cartridge having a transverse wall to close the inner end of said passage and the outer end of said passage being open, said chamber having an elongated recess in its top wall extending throughout the length of said chamber to provide a smoke passage along the top of said cartridge, said recess being in open communication With the radially outer absorbent surface of said cartridge, a stem connected to the outer end of said extension and having a passage extending longitudinally therein from end to end of said stem and open at both ends, the passage in said stem being aligned with and in open communication with the central passage in said cartridge so that moisture from said stern passage may pass into said central passage in said cartridge to be absorbed by the interior surface of said cartridge defining said central passage therein, a branch passage in said stem extending from said longitudinally extending passage therein vertically upwardly to said recess, said branch passage communicating with said longitudinally extending passage in said stem at a point spaced outwardly from the inner end 3 ,1 thereof and with said' recess at a pointoutwardly beyond said cartridge, and a vertical passage connecting the bottom of said tobacco receiving portion with the top of said chamber at the inner end thereof directly above and in open communication with the inner end of the radially outer absorbent surface of said cartridge.
