 1. Field of the Invention
 The present invention relates generally to smoking devices. More particularly, the invention concerns a smoking pipe in which the smoke is drawn from a smoking material receiving bowl through water and then into a mouthpiece into the mouth of the user.
 2. Discussion of the Prior Art
 Smoking devices in which the smoke from the smoking material is drawn through water before inhaling are not new. These types of smoking devices, which are sometimes called “water pipes”, have been in use throughout the world for many years.
 A common type of prior art water pipe comprises a liquid-accumulating glass flask having a mouthpiece associated with the upper portion thereof. A pipette or tube typically extends into the flask to a point above the bottom thereof. Disposed at the top of the pipette is a smoke-receiving bowl. The glass flask is usually provided with an opening that sealably receives an apertured rubber stopper which accepts the pipette in a manner to provide an air tight seal between the pipette and the flask. Exemplary of this type of apparatus is that disclosed in U.S. Pat. No. 3,882,875 issued to Frost.
 A common drawback of many of the prior art “water pipe” devices is that they are quite fragile and easily broken. Another drawback is that they are usually of a rather complex construction making them expensive to produce. These and other drawbacks of the prior art devices are effectively overcome by the novel apparatus of the invention which comprises sealably interconnected metal components that cooperate to provide a sturdy smoking pipe that is easily transportable and is highly reliable in use.
 By way of summary, the present invention comprises a novel smoking pipe having a generally cup-shaped stainless-steel, liquid-containing chamber; a stainless-steel connector segment sealably connected to the liquid-containing chamber, the connector segment having a tapered side wall and an aperture formed in the side wall; an elongated, generally cylindrically shaped, stainless-steel tube receivable within the aperture formed in the side wall, the elongated tube having a first end disposed within the liquid-containing chamber and a second end; a stainless-steel smoking material receiving bowl assembly removably connected to the second end of the elongated tube; and a generally cylindrically shaped, stainless-steel mouthpiece sealably connected to the connector segment.
 It is an object of the present invention to provide a smoking pipe which is of a novel stainless-steel, modular, slip-fit design having an external sealing system comprising a plurality of elastomeric sleeves which sealably interconnect the components of the modular design.
 Another object of the invention is to provide a smoking pipe of the aforementioned character that is compact and can be readily dissembled for ease of transport and storage.
 Another object of the invention is to provide a smoking pipe as described in the preceding paragraph which is dishwasher safe, is easy to clean and, being heat resistant, can readily be sterilized if desired.
 Another object of the invention is to provide a smoking pipe of the unique design described in the preceding paragraphs which is extremely durable and virtually unbreakable in normal use.
FIG. 1 is a generally perspective view of one form of the smoking device of the invention.
FIG. 2 is a generally perspective, exploded view of the smoking device shown in FIG. 1.
FIG. 3 is a cross-sectional view taken along lines 3-3 of FIG. 1.
 Referring to the drawings and particularly to FIGS. 1 and 2, one form of the smoking pipe of the present invention is there illustrated and generally designated by the numeral 12. As best seen by referring to FIG. 2, the smoking pipe here comprises a generally cup-shaped, stainless-steel, liquid-containing component 14 having a side wall 16 and a bottom wall that cooperate to define a liquid containing chamber 20. Slidably interconnected to liquid containing component 14 is a stainless steel connector segment 22 having a tapered side wall 24. Tapered side wall 24 interconnects and spans a first, generally cylindrically shaped skirt portion 26 that telescopically receives the generally cylindrically shaped wall 16 of the liquid containing component. Connected at the upper extremity of tapered side wall 24 is a second generally cylindrically shaped skirt portion 28 which is telescopically received within an upwardly extending, generally cylindrically shaped, stainless-steel mouthpiece 30.
 Tapered side wall 24 is provided with an aperture 32 which slidably receives a generally cylindrically shaped, stainless-steel tube 34 having a first portion 34 a disposed within liquid containing chamber 20 (FIG. 3) and a second portion 34 b that extends angularly outwardly from tapered side wall 24. Removably connected to second portion 34 b of tube 34 is the novel smoking material receiving bowl assembly of the invention that is generally designated by the numeral 36. As best seen by referring to FIG. 3, smoking material receiving bowl assembly 36 comprises a stainless-steel body 38 having an upper portion provided with a tapered smoking material receiving chamber 40 and a lower portion provided with a counter bore 42 for closely receiving the end of second portion 34 b of elongated tube 34. Importantly, body 38 is constructed of a single piece of material, has no threads and is virtually indestructible. Accordingly, the smoking material receiving bowl assembly is unique and comprises a substantial improvement over the prior art.
 With the modular components of the smoking pipe assembled in the manner shown in FIG. 3, a first sealing means is provided for sealably interconnecting liquid containing component 14 with connector segment 22. This first sealing means is here provided in the form of an elastomeric sleeve 44 that is adapted to sealably span the joint between liquid containing component 14 and connector segment 22 in the manner shown in FIG. 3. A second sealing means is also provided for sealably interconnecting connector segment 22 with mouthpiece 30. The second sealing means also comprises an elastomeric sleeve 46 that sealably spans the joint between connector segment 22 and mouthpiece 30 in the manner shown in FIG. 3. With the modular components of the smoking pipe assembled in the manner shown in FIGS. 1 and 3, liquid containing component 14, connector segment 22 and mouthpiece 30 are axially aligned and the components are sealably interconnected by the sealing means or elastomeric sleeves 44 and 46.
 As indicated in FIGS. 1 and 3, tubular member 34 is sealably connected to connector segments 22 by a third sealing means here provided in the form of a generally annular shaped, elastomeric collar 50. As best seen in FIG. 3, collar 50 includes a circumferentially extending groove 50 a which sealably receives side wall 24 and a central opening 50 b that sealably engages the outer wall of tubular member 34. With this construction, tubular member 34 is sealably connected to connector segment 22, but can be adjusted inwardly or outwardly to properly position portion 34 a with respect to the liquid contained within chamber 20.
 Provided proximate the upper portion of mouthpiece 30 is an elastomeric ring-shaped member 54 that is adapted to sealably cover the mouth of the user. Additionally, a third elastomeric sleeve 56 circumscribes body 38 of bowl assembly 36 to protect the fingers of the user from being burned when the smoking material is placed within chamber 40 and ignited.
 With the construction described in the preceding paragraphs, it is apparent that the overall height of the smoking pipe can be adjusted by telescopically moving mouthpiece 30 relative to connector segment 22 and by telescopically moving connector segment 22 relative to liquid containing component 14. It is also apparent that the smoking pipe of the invention can be readily dissembled for ease of transport and storage.
 Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
