Description

Patented Sept. 17, 1940 UNITED STATES PATENT, OFFICE 1 Claim.

This invention relates to smoking pipes.

The object of the invention is to provide a tobacco pipe with a moisture chamber between the bowl of the pipe and the mouth piece and separated from direct communication with the.

tobacco, or combustion chamber of the pipe bowl.

A further object of the invention is the provision of a smoking pipe embodying the above features in which the moisture and nicotine enters the moisture chamber at the mouthpiece end of the moisture chamber only.

A further object of the invention resides in the forming of a smoke passage by the connecting of a longitudinal stem groove, a transverse stem passage and a longitudinal stem and mouth piece passage.

A still further object of the invention resides in the provision of a pipe which can be readily cleaned of foreign substance, provide a cool smoke, a perfect draft, compact and. simple in structure and comparatively inexpensive in the cost of manufacture.

With the above and other objects in View, as will be apparent hereinafter, the invention consists in the novel features of construction, arrangement and combination of parts, hereinafter more fully described and finally pointed out in the claim hereto appended.

Referring to the accompanying drawing, wherein like characters of reference denote similar parts throughout the several views:

Fig. 1 is a longitudinal sectional view of a tobacco pipe embodying the features of my invention.

Fig. 2 is a longitudinal sectional view of the pipe bowl and bowl stem.

Fig. 3 is a longitudinal sectional view of the mouth piece, or bite and its cylindrical projecting stem.

Fig. 4 is a view looking in the direction of the arrow in Fig. 2.

Fig. 5 is a top plan View of the mouth piece and its projecting stem.

Fig. 6 is an enlarged sectional view of the 45 mouth piece stem taken on line 6--B of Fig. 5.

Fig. 7 is an enlarged sectional view of the mouth piece stem taken on line 1-1 of Fig. 5.

Briefly, in carrying out the invention, I provide a smoking pipe with a stem having separable parts, including a plurality of smoke passages and a moisture and nicotine chamber out of direct communication with the combustion chamber of the pipe bowl.

In the drawing, there is shown a suitable bowl I, having a combustion chamber 2 in which tobacco is adapted to be placed for smoking. The bowl I is provided with a bowl stem part 3 formed integral therewith and having a longitudinalbore 4 inwardly from the free end thereof and stopping at its inner end short of the combustion chamber 2 to form a solid wall 5. The Wall material 5 between the combustion chamber 2 and the bore 4 is provided with a smoke inlet passage 8. The smoke inlet passage 6 is out of axial alignment with the bore 4 and to the upper side thereof. The smoke inlet passage 6 communicates at one end with the side wall ofthe combustion chamber near the bottom thereof, and, at its opposite end with the face of the solid wall 5, as clearly shown in Fig. 2.

I also employ a suitable mouth piece part I provided with a bite 8 and having .a bore or smoke outlet passage 9. The mouth piece 1 includes a cylindrical stem I0 projecting from one end thereof and is provided with a relatively short smoke outlet passage H, which passage II is a continuation of the mouth piece smoke passage 9.

The cylindrical mouth piece stem Wis adapted to be fitted snugly into the bore 4 of the bowl stem part 3 to form a tight joint therebetween; The mouth piece stem l0 serves as means for disconnectively connecting the mouth piece 1 with the bowl stem part 3 to close the bore 4 from communication with the combustion chamber 2, as clearly shown in Fig. 1.

The cylindrical mouth piece stem I0 is provided on its upper side with a longitudinal groove ID, as shown in Figs. 3, 5 and 6, and when fitted in the bore 4 forms a smoke inlet channel l2, which channel communicates directly with the smoke inlet passage 6 when the bowl stem part and the mouth piece part are fitted, or joined together through the medium of the stem II], as shown in Fig. l. The groove l0 starts at the free end of the stem l0 and stops short of the juncture of the stem II] with the mouth piece I, as shown in Figs. 3 and 5. The stem lfl being less in outside diameter than the mouth piece 1, and when the separable pipe stem parts are fitted, or joined together, the end face l3 of the bowl stem 3 will tightly engage the mouth piece shoulder l4, and, the flat end face I5 of the stem 10 will tightly engage the end face l6 of the bowl.

stem wall 5 to form a perfect joint between the stem l0 and bowl stem part 5.

The lower half of the mouth piece stem It, as clearly shown in Fig. 3, is provided with an elongated cutaway portion, or recess intermediate the ends thereof, providing thereby a fiat ceiling surface I1, and the inclined end walls I8 and. I9. The free end portion of the stemv I provides a head adjacent the inclined wall I8 so that the edge of the wall I8 forms a scraping edge 2i], as clearly shown in Fig. '7.

{A suitable transverse smoke, moisture and nicotine inlet passage 2| is formed in the mouth piece stem I6 and it connects the mouth piece end of the stem groove It with the like end of the elongated recess formed on the lower half of the stem IE3. When the stem H3 is positioned in the bore 4 of the bowl stem part 3, the inlet passage ZI is disposed vertically relative to the stem groove I0 and the stem recess therebelow so that the lower end of the inlet passage 2! serves as a fluid, moisture and nicotine outlet. The axial stem passage I I, which is a continuation of the mouth piece smoke passage 9, terminating with one side of the vertical inlet passage 2!, permits only pure smoke to pass into the stem passage II and then into and out of the mouth piece passage 9 to provide for a clean, cool smoke.

When the mouth piece stem Ill is fitted into the bore of the bowl stem part 3, the cutaway portion, or recess on the lower side of the mouth piece stem I0 provides a fluid or moisture and nicotine chamber 22 between the walls I'I, I8

and I9 of the mouth piece stem It and the wall of the bore 4 in the bowl stem 3, as clearly shown in Fig. 1 so that when smoking the pipe, fluid, such as moisture and nicotine will flow downwardly through the vertical passage 2i directly into the nicotine chamber 22, which leads back toward the combustion chamber of the pipe bowl below the smoke groove it and not directly connected with the combustion chamber of the pipe bowl.

It will be observed from Fig. 1 of the drawing, that when the pipe bowl stem part and the mouth piece stem part are assembled, that the stem channel I2 is in alignment and in direct communication with the smoke inlet passage 6 so that smoke will travel through irregular path, or course to the smoke passage in the mouth piece, and, that the heavy liquid substance such as moisture and nicotine will be deposited in the chamber 22 below and behind the vertical passage 2| so that it cannot be drawn through the mouth piece passage, and, in no instance can smoke pass directly from the pipe bowl through the nicotine receiving chamber 22 to the mouth piece passage, thereby providing a clean, cool smoke.

Also, it will be observed it is easy to clean the smoke groove II on the stem I0 when the stem is removed from the bowl stem bore 4, by wiping the same out, and, the vertical passage 2 I, as well as the smoke passages 9, I I and I'll can be readily cleaned with a pipe cleaner, or the like. The bowl stem passage can also be readily cleaned when the mouth piece stem I0 is disconnected from the bowl stem part 3.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device for this purpose has been disclosed, but it is to be understood that I have illustrated and described a preferred embodiment only of the invention and do not desire to restrict, or limit myself to the very details of the construction shown and described, which is merely illustrative, it being obvious that changes, not involving the exercise of invention, may be made without conflicting or departing from the spirit of the invention within the scope of the appended claim.

What I claim is:

In a smoking pipe, the combination with a bowl having a tubular neck and a mouth piece having a smoke passage, of a solid stem projecting from,

the mouth piece and receivable within said neck, said stem being cylindrical at opposite ends and semi-cylindrical intermediate said ends with the plane surface of the semi-cylindrical intermediate portion adapted to be spaced from the, bottom surface of the inner wall of the bowl neck to provide a nicotine chamber below the stern portion only, said bowl having a bowl passage and said stem having a vertical passage communicating at its lower end with the forward end of the nicotine chamber and communicating intermediate its ends with the mouthpiece smoke passage, the upper curved face of the stem being provided with a longitudinal smoke groove communicating at one end and in axial alignment with said bowl passage and communicating at its opposite end with the upper end of said vertical passage.
