' ERVIN A. KUBERT REECE ALLDAY ATTORNEY United States Patent O 3,463,167 SMOKING PIPE Ervin A. Kubert, 1328 Smilax Ave., Fort Worth, Tex. 76111, and Reece Allday, 3536 Montreal Circle, Fort Worth, Tex. 76117 Filed `Iuly 24, 1967, Ser. No. 655,451 Int. Cl. A24f 1/08, 1/16, .7/20

U.S. Cl. 131-202 3 Claims ABSTRACI` OF THE DISCLOSURE A smoking pipe including a bowl, a mouthpiece and a tubular stern extension therebetween. Within the extension there is an inner tube or duct connected with the bowl, around the duct and spaced therefrom there is a tube having a closed end and around the tube there is a filter. Filling the space between the filter and the inner surface of the stem extension there is a layer of absorbent material for absorbing any saliva entering the pipe through the mouthpiece. A feature of the invention has to do with fingers on the filter making contact with the absorbent material so as to transfer moisture from the fingers to the absorbent material.

This invention relates to smoking pipes and has reference to a combined filter and moisture absorbent for reducing the amount of so called tars from reaching the mouth and for preventing moisture from reaching the tobacco in the pipe bowl. Additionally, the path of the smoke is greater than the length of the pipe, thereby cooling the smoke before reaching the mouth. The path of the smoke also includes a moisture trap for further preventing moisture in the mouthpiece from reaching the bowl and the tobacco therein.

`One object is to provide a smoking pipe which does not go out readily because moisture from the mouthpiece does not reach the bowl.

Another object is to provide a pipe having an absorbent and filter, both of which are easily replaced.

These and other objects of the invention will Ibecome apparent from the following description and the accompanying drawing, in which:

FIGURE 1 is a longitudinal sectional view of a smoking pipe according to the invention.

FIGURE 2 is an enlarged perspective view, shown partly in section, of the bowl fitting, mouthpiece, stem extension and parts contained therein.

FIGURE 3 is a side elevational view of the moisture absorbent.

FIGURE 4 is an enlarged end view of the absorbent, filter and the closed end of the tube.

FIGURE 5 is a fragmentary perspective view of a preferred filter construction in sheet form before rolling lengthwise, and

FIGURE -6 is an enlarged broken longitudinal sectional view showing the outlet end of the duct, the closed end of the tube and the filter therearound.

The pipe shown in the drawing includes a bowl 10, a mouthpiece 11 and a tubular stem extension 12 therebetween. The mouthpiece 11 is attached to the stern extension 12 by threads 13, whereas the remaining end of the extension is attached to the stern 14 of the bowl by a fitting 15. As best shown in FIGURE 2, the fitting 15 is comprised of forward threads 16 which engage the bowl 10, rear threads 17 which engage the stem extension 12 and a fiange 18 therebetween. There is an 'ice axial opening 19, and pressed into the opening there is a rearwardly extending tubular duct 20. The duct 20 extends nearly the length of the stern extension 12 and is open at both ends. However, there are lateral openings 21 near the rear end of the duct 20 to facilitate the flow of smoke. Around and spaced from the duct 20, and extending rearwardly thereof, there is a tube 22 having a closed rear end 23. The forward end of the tube 22 is spaced rearwardly from the fitting 15 to provide a lateral passage 24 which is best shown in FIGURE 2 (see also FIGURE 1). Within the scope of the invention any suitable filter may be provided around the tube 22, but a preferred filter 25 is comprised of a length of paper 26 having punched vertically extending fingers 27. The length of paper 26 is wrapped, lengthwise, around and may be bonded to the tube 22 by means of a suitable adhesive with the fingers 27 projecting outwardly. Within the stem extension 12, and extending between the fitting 15 and the mouthpiece 11, there is a tubular absorbent 28, the outer diameter of which is in contact with the inner surface of the extension and the inside diameter contacts the outer ends of the filter fingers 27. The absorbent may be made of various materials, for example, paper towels, cotton batting, wood pith, etc. Glue (not shown) on the ends of the fingers 27 may be used to secure the absorbent 28 to the filter 25. There is a longitudinal groove 29 in the bottom inner surface of the mouthpiece to direct liquid in the latter to the absorbent 28.

In operation, tobacco is placed in the bowl 10 in the usual manner and lighted while drawing on the mouthpiece 11. Smoke travels from the bowl 10, through the opening 19 in the fitting 15, and out through the end of the duct 20. By reason of the closed end 23 on the tube 22, the smoke then travels forward through the tube, through the lateral passage 24, rearwardly through the filter 25 and thence out through the mouthpiece 11. The tortuous path of the smoke cools the same and at the same time the filter 25 and contact with the absorbent 28 removes a substantial amount of the so called tars and other extraneous matter. Since an end of the absorbent 28 is in direct contact with the mouthpiece 1'1, accumulated saliva is readily absorbed. Additionally, any excess moisture in the absorbent 28 cannot reach the bowl because the described arrangement of the tube 22 and duct 20 serves as a moisture t-rap.

The invention is not limited to the exemplary construction herein shown and described, but may be made in various ways.

What is claimed is:

1. In a smoking pipe including a bowl, a mouthpiece and a stem extension connected therebetween, means providing a duct in communication with said bowl and extending rearwardly therefrom into said stem extension, a tube around and spaced from said duct, a closure on the rear end of said tube, lateral passage means at the forward end of said tube, passage means around said tube communicating said lateral passage means with said mouthpiece, a tubular absorbent within said stem extension and a filter around said tube and in contact with the inner surface of said tubular absorbent.

2. In a smoking pipe as defined in claim 1, the construction wherein said filter is comprised of a tube having lateral fingers extending to and in contact with said tubular absorbent.

3. In a smoking pipe as defined in claim 1 and including means providing a longitudinal internal groove in the bottom inner surface of said mouthpiece and in communcation with said tubular absorbent.
