JOHN A. HUG-HSON, 9F NEW YORK, N. Y.

ronaoco rrrn Application filed August 18, 1923.

To all whom it may concern:

Be it known that l, JOHN A. l-luorrson, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Tobacco Pipe, of which the following is a specification.

This invention relates to improvements in pipes and is more especially directed to a to pipe wherein the smoke passage may be kept free horn deposits of nicotine and saliva through the employment of an associated sump in which such saliva and nicotine are adapted to be trapped.

lhe invention is more especially characterized by the construction wherein both the stem of the bowl and the mouth piece are provided with a liner in the form of a removable tube, intermediate the ends of so which is associated anintegral sump. The

liner tube with its associated sump may be removed from the pipe parts for cleaning and the sump preferably contains a short length of pipe cleaner, the absorbent oharacteristics of which cause the saliva and nicotine to be taken up by the cleaner. When the pipe is cleaned the cleaner is removed and thrown away and a new one positioned in the sump.

The advantage of the foregoing construction is that no smoke, saliva or nicotine come into contact with the bore or the stem or mouth piece, and consequently these parts are kept sweet and clean.

Other features of advantage will be apparent from the following detailed description when read in conjunction with the ac companying drawings and the appended claims.

The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure l is a section of a pipe embodying this invention, the parts being shown in assembled relation.

Figure 2 shows the pipe parts dismantled and the liner and sump removed.

Figure 3 is a perspective view of a liner and sump with the cleaner removed.

Figure l is a section on the line H of Figure 3.

Referring to the drawings, 1 designates the bowl of the pipe, having a suitable stem 2 with which is associated a mouth piece 3.

Serial No. 858,019.

The bowl, stem and mouth piece may be of any suitable material or shape as these features constitute no part of the present invention.

The stem 2 is provided with a bore 4: and the mouth piece 3 is provided with an alined bore 5, so that a liner tube 6 can be received within these bores collectively, when the parts are assembled and the liner tube, as shown in Figure 8, may, in practice, be in the form of a metal tube of sufiicient length to reach from the hollow in the bowl to the distant end of the mouth piece when the parts are assembled as shown in Figure 1. This tube is, however, adapted to have a sliding fit with the bores l and 5, so that, when the mouth piece is removed, the tube can be removed from both the mouth piece and the stem 2.

Associated with the tube 6 and adjacent the end thereof which occupies the stem 2 is a sump 7. This sump may be conveniently formed from a short length of tubing similar to the tubing 6 and is Welded, soldered or otherwise secured to the tube 6 in a substantially line contact therewith and in parallel relation thereto. Along this line of contact the walls of the two tubes are cut away forming a communicating slot 8, as best shown in Figure 4c, and this slot extends an appreciable distance longitudinally of the tube 7 as shown in Figure l, but not "for the full length of this tube.

The stem 2 is cut away to provide a supplemental bore 9 to receive the sump 7 as shown best in Figures 1 and 2, and the parts are so proportioned that when they are removed, the bowl end of the bore or passage 9 will close the corresponding end of the sump while the opposite end of the sump will be closed by the end of the mouth piece.

It will be apparent that with a pipe so constructed, nicotine, saliva or other liquid or semi-liquids passing through the liner tube 6 will gravitate through the slot 8 and into the sump 7, so that such extraneous materials will be trapped out and will not enter the mouth of the smoker or the bowl of the pipe.

The parts are normally assembled for use as shown in Figure l, where, it will be noted, the liner tube 6 extends the full length of the smoke passage so that, as the smoke traverses this passage, it does not come into contact with either the stem 2 or the mouth piece 3. Nicotine, saliva and other extraneous matter accumulate in the cleaner 1O positioned in the sump and the pipe remains clean and sweet for a long period. At suitable intervals, however, the parts should be dismantled as shown in Figures 2 and 3 for the purpose of removing and discarding the small absorbent cleaner section 10. This can be readily accomplished because of the fact,

that both ends of the sump are open. An ordinary pipe cleaner may, at the same time, be passed through the liner tube 6 to thoroughly clean it, and, after a new section of cleaner is positioned in the sump, the parts of the pipe may be reassembled to prepare it for further use.

It will, thus be manifest that the pipe of this invention may be readily maintained in a clean and sanitary condition andthat the drawing of nicotine from the bowl of the pipe into the smokers mouth, as has heretofore been a common occurrence, is entirely obviated. I consider the possibility of renewal of the liner tube for the purposes of cleaning, highly important and advantageous as it permits a thorough cleaning of the parts. I further consider the use of a liner tube substantially coextensive with the smoke passage of considerable importance, since the parts of the pipes are not subjected to contact with saliva or impurities.

The accompanying drawings show the invention in its preferred practical form, but this invention is to be understood as fully commensurate with the appended claims.

Having thus fully described my invention, what I claim as new, and desire to obtain by Letters Patent is z 1. A tobacco pipe embodying a bowl, it. stem associated with the bowl and provided with a smoke passage, and a mouth piece associated with the stem and also having a smoke passage, in combination with a liner tube extending substantially the full length of the combined smoke passages of the stem and mouth piece, and a sump associated with the liner tube intermediate its ends and communicating with the interior of the liner tube, said sump being housed in concealed position within the pipe.

2. A'tobacco pipe embodying a bowl, a stem associated with the bowl and provided with a smoke passage, and a mouth piece associated with the stem and also having a smoke passage, in combinationwith a liner tube extending substantially the full length of the combined smoke passages of the stem and mouth piece, a sump associated with the liner tube intermediate its ends and communicating with the interior of the liner tube, said sump being housed in concealed position within the pipe, and absorbent ma.-

terial positioned within the sump and adapted to collect the liquid and semiliquids entering the sump.

3. A tobacco pipe embodying a bowl, a stem associated with the bowl and provided with a smoke passage, a mouth piece detachably associated with the stem and also having a smoke passage, in combination with a liner tube extending substantially in full length of the combined smoke passages. of the stem and mouth piece, and a sump associated with the liner tube intermediate its ends and communicating with the interior of the liner tube, said liner tube and sump being removable from the stem and, mouth piece to facilitate cleaning, when the mouth piece is detached from the stem.

4. A tobacco pipe embodying a bowl, a stem associated with the bowl and provided with a smoke passage, a mouth piece detachably associated with the stem and also having a smoke passage, in combination with a liner tube extending substantially in full length of the combined smoke passage of 1 the stem and mouth piece and a sump associated with the liner tube intermediate its ends and communicating with the interior of the liner tube, said liner tube and sump being removable from the stem and mouth piece to facilitate cleaning, when the mouth piece is detached from the stem, and absorbent material positioned within the sump and adapted to collect liquids and semiliquids entering the sump, said absorbent material being removable from the sump when the liner tube and sump are detached from the stem and mouth piece.

5. A tobacco pipe embodying a bowl, a stem associated with the bowl and provided with a smoke passage, and the mouth piece associated with the stem and also having a smoke passage, in combination with a liner tube extending substantially the full length of the combined smoke passages of the stem and mouth piece, a sump extending longitudinally of the liner tube for a distance less than the length of the tube and provided with the passage communicating with the interior of the liner tube, the opposite ends of the sump being open, and absorbent material within the sump, the opposite ends of the sump being adapted to be closed by abutting portions of the stem and mouth piece when the parts are in assembled relation, and the liner tube and sump being removable from the stem and mouth piece to facilitate cleaning and removal of the absorbent material, when the mouth piece is removed from the stem.

In testimony whereof I have signed the foregoing specification.
