My invention relates to tobacco smoking pipes.

An important object of the invention is to provide a pipe which will produce a cool smoke.

A further object of the invention is to provide 1'. a pipe having means for withdrawing the smoke at a point spaced from the bottom of the bowl of the pipe, whereby certain impurities will remain in the bottom portion of the bowl.

A further object of the invention is to provide it means for distributing the suction action of the pipe around the periphery of the bowl.

A further object of the invention is to provide means whereby any number of upper bowl-sections may be used in connection with the lower It bowl-section, thus enabling the user to have a number of pipes differing in appearance.

A further object of the invention is to provide means whereby different stems may be used in connection with the bowl.

251 Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are 2.5 employed to designate like parts throughout the same:

Figure l is a perspective view of the tobacco smoking pipe embodying my invention,

Figure 2 is a central vertical longitudinal sec- 30 tion through the same,

Figure 3 is a horizontal section taken on line 3--3 of Figure 2,

Figure 4 is an exploded perspective view of the pipe, parts broken away, and,

35 Figure 5 to 8 inclusive are side elevations of upper bowl sections of different shapes.

In the drawing, wherein for the purpose of illustration are shown preferred embodiments of my invention, the numeral I ll designates the bowl ,0 of the pipe, as a whole, comprising an upper bowlsection I I and a lower bowl-section I2. The upper bowl-section II is considerably longer than the lower bowl-section I2. Preferably formed integral with the lower bowl-section I2 is a stem sec- 45 tion I3, as shown. I

The bore of the upper bowl-section H is preferably counterbored, as shown at I4, for receiving a cylindrical sleeve I5, which may be formed of metal or the like, and held within the counter- 50 bore by a friction fit or by any other suitable means. The sleeve I5 is open at its opposite ends and the lower portion of the sleeve is screwthreaded, as shown at I5, to engage with screwthreads I7, formed in the side of the bore I8 oi 55 the lower bowl-section I2. It is thus seen that the sleeve I5 serves as means to detachably conmeet the upper bowl-section II with the lower bowl-section I2, these bowl sections contacting at I9, to form an air-tight fit. The sleeve I5 is provided with a horizontal annular set of apertures 5 preferably punched outwardly, and this annular set of apertures is arranged at a point generally equi-distantly spaced from the opposite ends of the sleeve I5. At its lower end, the upper bowlsection I I is provided at its lower end with an in- 10 ternal annular cut-away portion forming an internal frusto-conical wall 2|. The lower bowlsection I2 is provided at its upper end with an internal annular cut-away portion providing an internal frusto-conical wall 22. The frusto-conical walls 2| and 22 register, providing an internal annular chamber, which increases in width inwardly toward the sleeve I5. This sleeve I5 extends across the inner open end of the annular chamber 23 and the annular set of outwardly stamped apertures 20 lead into the annular chamber 23, the free ends of the apertures being spaced from the frusto-conical walls 2| and 22, as shown. The sleeve I5 extending across the inner open side of the annular chamber 23 pre- 25 vents the tobacco from entering this annular chamber, while the apertures 2!] permit of the passage of the smoke. The sleeve I5 also serves to detachably connect the upper and lower bowlsections Ii and I2. When thebowl-sections II and I2 are separated, the sleeve I5 may be removed from the upper bowl-section and the frusto-conical walls 2i and 22 may be readily cleaned or wiped off.

The stem section I3 is provided with a port or passage 24, which is forked at its forward end, providing passages 25, leading into the annular groove 22. The stem section I3 has a screwthreaded recess 26, formed in its end to receive a screw-threaded extension 27, carried by a stem section 28, having a bore 29, in communication with the bore 25. The stem section 28 has the usual bite 38. It is obvious that the stem section 28 is detachably secured to the stem section I3 and that stem sections of dilierent shapes and lengths may be secured to the stem section I3, when desired.

In Figure 4, I have shown an upper bowl-section Ila, which is circular in cross-section and tapers downwardly. This bowl-section has the sleeve I5 and associated elements and is otherwise identical with the bowl-section II. In Figure 6, I have shown a bowl-section II b which tapers upwardly and downwardly and is circular in cross-section. The bowl-section N19 has the same sleeve l and associated elements and is otherwise identical with the bowl-section II. In Figure 7, I have shown a bowl-section llc having a wider intermediate portion 3| and oppositely tapering end portions 32 and provided with the sleeve Hi. This bowl-section is otherwise identical with the bowl-section H. In Figure 8, I have shown a bowl-section lld, having an intermediate cylindrical portion 33 and oppositely tapering portions 34 and the sleeve l5. This bowlsection lid is otherwise identical with the bowlsection ll. The bowl-section H may be removed from the bowl-section l2 and any one of the upper bowl-sections shown in Figures 5, 6, '7 and S, substituted therefor.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A tobacco smoking pipe comprising a bowl, said bowl comprising separate upper and lower bowl-sections having engaging ends, said bowlsections being provided at their engaging ends with circumferentially extending internal cutaway portions, said cut-away portions when assembled forming a circumferentially extending internal recess having its inner side open, a tubular element arranged within the bowl-sections and extending across the open side of the circumferentially extending recess and having apertures in communication with the recess, said tubular element serving to cover the open side of the recess to prevent the tobacco from entering the recess and to also detachably connect the bowl-sections, and a stem having a passage in communication with the circumferentially extending recess.

2. A tobacco smoking pipe comprising a bowl including separable upper and lower bowl-sections, the lower bowl-section being provided at its upper end with an internal frusto-conical wall which flares upwardly, the lower bowl-section having a port in communication with the internal frusto-conical wall, the upper bowl-section being provided at its lower end with an internal frusto-conical wall which flares downwardly, the assembled frusto-conical walls forming an annular recess which increases in width inwardly toward its inner open side, a tubular element removably mounted within the upper bow1-section and projecting into the lower bowlsection and being removably mounted therein, the tubular element extending across the inner open side of the annular chamber and also serving to detachably connect the bowl-sections, the tubular element having opening means leading into the annular chamber, and a stem secured to the lower bowl-section and having a bore in communication with said port.

3. A tobacco smoking pipe comprising a bowl including separable upper and lower bowl-sections, the lower bowl-section having internal threads and provided at its top with an internal frusto-conical wall and also having a stem, said stem having a longitudinal passage which is forked to provide passages extending upwardly and leading through the frusto-conical wall, the upper bowl-section being provided at its lower end with an internal frusto-conical wall to register with the internal frusto-conical wall of the lower section, said frusto-conical walls when assembled forming an annular chamber having its inner side open, a sleeve removably held within the lower portion of the upper bowl-section and projecting below the same and having its lower portion screw-threaded to enter the lower bowl-section and engaged with the threads thereof for detachably connecting the upper and lower bowl-sections, said sleeve extending across the open inner side of the annular chamber and being provided between its ends with an annular set of circumferentially extending apertures leading into the annular chamber.
