The present invention relates generally to smoking pipes and particularly to a novel improved smoking pipe which provides advantages relating to the comfort of the user in addition to improving the ease in which the pipe can be cleaned.

In general, the smoking pipe of the present invention comprises a bowl provided with a tobacco receiving cavity and an outlet vent in the bottom of the cavity. The bowl includes an outlet opening extending through its lower portion which communicates with the outlet vent. A stem means is provided with a nest portion which receives the lower portion of the bowl and includes a tubular portion extending outwardly from the bowl which is aligned with the outlet opening. A condenser portion is slideably mounted in the stem portion and includes an inner end slideably mounted through the outlet opening in the bowl. The bowl, the stem means and the condenser portion include means which cooperate to provide positive alignment of the bowl and condenser portion. The condenser portion includes means which cooperates with the tubular portion to form an effective longer passage means for the smoke to travel compared to the actual length of the condenser portion or the tubular portion of the stem means.

It is therefore an object of the present invention to provide a smoking pipe of the type described wherein the stern portion through which the smoke travels has an increased effective length relative to its actual length so as to deliver a cooler, drier, more comfortable smoke to the user.

It is another object of the present invention to provide a smoking pipe which can be readily disassembled into components for ease of cleaning and then reassembled in a simple, quick manner.

It is another object of the present invention to provide a smoking pipe of the type described which combines the advantages mentioned above and yet is of a relatively simple construction.

It is a further object of the present invention to provide a smoking pipe of the type described which includes constructional features which assure proper positioning and alignment of the component parts upon re-assembly.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein preferred forms of embodiments of the invention are clearly shown.

Referring in detail to the drawings a preferred embodiment of a smoking pipe constructed in accordance with the present invention is illustrated in FIGS. 1 and 2 and includes a bowl, indicated generally at 20, provided with a tobacco receiving cavity 22. Cavity 22 includes an outlet vent 24 which communicates with an outlet opening 26 which extends through the lower portion of bowl 20 below cavity 22.

A stem means, indicated generally at 28, includes a tubular portion and condenser portion, indicated generally at 30 and 32 respectively.

Tubular portion 30 includes a nest portion 34 adapted to receive the generally rounded cone-shaped lower portion of bowl 20 which forms a bowl seating means 21 in such a manner that outlet opening 26 is substantially aligned with the inner opening 35 of tubular portion 30.

The bowl seating means 21 includes a shoulder 25 spaced from a shoulder 27 which is formed on a bottom lug portion 29 which is received in an aperaturc 36 pro vided in nest portion 34. Shoulder 2S mates with a shoulder 31 formed on the upper portion of nest portion 34 in conjunction with shoulder 27 and the aperature 36 to automatically vertically align through outlet 26 with tubular opening 35 in the inner end of tubular portion 30 and hole 38 in nest portion 34. Hole 38 is disposed opposite tubular opening 35.

Hole 38 is substantially the same size as through outlet 26 such that one may freely rotate bowl 22 and obtain proper alignment of hole 38 and outlet 26 in a convenient manner without the aid of any tools or the like.

Condenser portion 32 is slideably and removably mounted in tubular portion 30 and includes an inner end portion 37 which extends through opening 35, outlet opening 26 in bowl 22 and into hole 38 provided in nest portion 34 to hold bowl 22 in position in nest portion 34.

The inner end portion 37 is provided with a tapered or beveled surface 39 which mates with the general taper or conical configuration of nest portion 34 so as to fit flush with the outer surface of nest 34 when fully extended through outlet opening 26 and hole 38.

As best seen in FIG. 2, when beveled end 39 is positioned flush with the outer surface of nest 34, the user may visually be assured that the outlet vent 24 from cavity 22 is positioned over the inlet of a spiral passage, described later herein, in condenser 32.

Condenser portion 32 also includes a spiral groove 40 defined between fins such as 42, which cooperate with the inner surface of tubular portion 30 to define a spiral path extending to a chamber 45 which communicates with the opening 44 or port of an outlet passage 46 provided in mouthpiece portion 48. It is important to point out that the spiral path or passage defined by groove 40 and tubular portion 30 provides a much longer effective path of travel for the smoke drawn from cavity 22 than the actual length of condenser portion 32 to permit cooling of the smoke and condensation of the tars and other irritants present in the smoke.

It is also important to point out that condenser portion 32 may be easily cleaned by the user by merely slideably removing it from tubular portion 30. Then the user may wipe away the condensates collected thereon with a piece of tissue or the like rather than the conventional rod-like pipe cleaners.

Now referring specifically to FIGS. 3 and 4, another preferred embodiment of a smoking pipe constructed in accordance with the present invention is illustrated and includes a bowl, indicated generally at 60, provided with a tobacco receiving cavity 62. Cavity 62 includes outlet vent 64 which communicates with an outlet opening 66 disposed in the lower portion of bowl 60 forming bowl seating means 61.

A stem means, indicated generally at 68 includes a tubular portion and a condenser portion, indicated generally at 70 and 72 respectively. Tubular portion 70 includes an integrally formed nest portion 74 adapted to receive the generallyconical lower portion 61 of bowl 60.

Condenser portion 72 is slideably and removably mounted in tubular portion 70 and includes an inner end portion 73 which extends through the opening 78 of the inner end of tubular portion 70, outlet opening 66 in bowl seating means 61, and in a hole 76 provided in nest portion 74 and aligned with opening 78.

The inner end portion 73 includes a beveled surface 75 and may include a hollow blind space 77. Space 77 provides an additional cooling-function for smoke passing from cavity 62 into condenser portion 72.

Condenser portion 72, the construction of which represents the basic difference between the embodiments of FIGS. 1 and 2 and FIGS. 3 and 4, includes a plurality of spaced longitudinal extending grooves or recesses 80. In the embodiment of FIGS. 3 and 4, threes grooves 80 are shown, a third groove 80 being on the hidden side of condenser portion 72 as seen in FIG. 3. Each of the grooves 80 are sequentially communicated to the next groove 80 by recessed

ports

84 and 86. The re cessed portion 82 provides a smoke admitting means to the first groove 80.

Therefore it can be readily understood that grooves 80 define a path of travel effectively longer than the actual length of condenser portion 72 similarly to the longer path defined by the spiral passage formed by groove 40 in the embodiment of FIGS. 1 and 2.

It is important to point out that the number of grooves 80 can be three or more depending upon the increased effective length desired without departing from the spirit of the present invention.

A filter means 82' is removably disposed in one of the grooves 80, preferably in the groove 80 communicating directly with outlet chamber 84 which in turn communicates with outlet passage 86 disposed in mouthpiece portion 88.

Filter means 82 can be composed of any type of conventional tobacco filter material and obviously traps a substantially portion of the tars and irritants present in the smoke and may be easily changed periodically by merely removing condenser portion 72 which is slideably and removably mounted in tubular portion in the same manner as in the first described embodiment.

It is important to point out that the combination of providing both a longer effective path of travel and the removable filter means in at least a portion of that path provides a cool, dry and comfortable smoke to the user, without increasing the actual length of the stem means compared to conventional pipe construction.

Now referring to FIGS. 5-12, a modified construction of a smoking pipe constructed in accordance with the present invention is shown and includes a bowl, indicated generally at 90, provided with a tobaccoreceiving cavity 92. Cavity 92 includes an outlet vent 94 which communicates with an outlet opening 96 which extends through a tapered lower portion of bowl 20 which forms a bowl seating means 91 below cavity 92. Bowl 20 also includes an upper shoulder 98 and a recess 100 adapted to receive an O-ring seal 102.

A stem means, indicated generally at 104, includes a generally conical nest portion 106 adapted to receive the tapered bowl seating means 91, and a tubular portion 108 extending outwardly from nest portion 106. The inner end of tubular portion 108 terminates in the beveled inner wall of nest portion 106 to form a hole 110.

One end portion of outlet opening 96 is provided with a recessed shoulder 112 and a lower outwardly extending annular shoulder or boss 114.

Annular shoulder 114 cooperates with the slanted hole in the inner wall of nest portion 106 to effectively assure proper vertical and rotational alignment between bowl seating means 91 and nest portion 106. Seating means 91 cannot be fully seated in nest portion 106 unless shoulder 114 is disposed in hole 110. In this manner it is easy to assure the user that opening 96 is in proper alignment with hole 110 and tubular portion 108.

A condenser portion, indicated generally at 116, is' slideably and removably mounted in tubular portion 108 and in cooperation therewith forms plural reversing smoke-receiving passages to treat the smoke before it reaches the user.

Condenser portion 116 includes an inner end portion 118 which extends through hole 110 and into outlet opening 96 and serves to removably secure bowl seating means 91 in nest portion 106.

Inner end portion 118 includes a less than semiround lower portion 120 and a generally flat upper portion 122 as seen in FIG. 11. Lower portion 120 terminates with a semi-annular shoulder 124 and upper portion 122 terminates with a semi-annular shoulder 126.

Shoulders

124 and 126 are longitudinally spaced from one another.

The middle portion of condenser 116 includes two generally flat recessed side portions 128 and 1311 respectively which join one another at a common edge 132 to define a generally V-shaped configuration, as best seen in FIG. S-A.

The upper side of this middle portion includes an annular recess or channel 134 which with side portions, 128 and 130 and in cooperation with the inner wall of tubular portion 108 form three smoke-receiving

passages

136, 138 and 140 to cool the smoke received from cavity 92.

Recesses

142, 144 and 146 define outlets from each of the smoke-receiving passages formed to assure that the smoke travels the defined plural reversing path.

The outer end of the middle portion of condenser 116 includes an annular recess 148 which is adapted to receive an O-ring seal 150 to prevent the inadvertent release of smoke or condensates from the tubular portion 100 other than through the defined smokereceiving passages and an outlet passage 152 which communicates with a similar passage 154 in a mouthpiece 156.

Channel 134 includes an outlet port 158 which communicates directly with passage 152.

In assembling, the pipe shown in FIGS. 5-12, the user first places bowl 90 in nest portion 106. Rotation of bowl 90 within nest portion 106 permits the user to be assured of proper alignment as bowl 90 will not be fully seated unless shoulder 114 is mated with the slanted opening 110.

Then condenser 116 is inserted into tubular portion 108 as far as possible. lnner end portion 118 is then extended through hole 110 and partially extended into opening 96.

It should be pointed out that mouthpiece 156 includes an annular shoulder 159 which should be engaging the outer end of tubular portion 108 when condenser 106 is fully extended into opening 96.

However, shoulder 124 on inner end portion 118 is constructed to abut outwardly extending shoulder 114 to define the predetermined rotational position of condenser 116 relative to the desired sequence of passages through which the smoke is passed.

If, for example, condenser 116 is inserted such that shoulder 124 is rotated out of phase with shoulder 114, shoulder 124 meets with interference with the tapered face of seating means 91. Therefore in this position, inner end 118 cannot be as deeply extended into hole 96 and this is visually transmitted to the user because shoulder 150 on mouthpiece 156 will not have engaged the end of tubular portion 108.

However, upon rotation of condenser 116 and with inward pressure, inner end 118 extends fully into opening 96 when shoulder 124 mates with shoulder 1 14 and shoulder 126 does not quite abut against shoulder 112, leaving a small clearance therebetween.

Further, in this position, recess outlet 146 is aligned to communicate with opening 96 to the exclusion of the other passages and therefore smoke first enters passage 130. Upon entering passage 138, it is communicated to passage 136 via recessed outlet 144, and then it reaches passage 140 via recess 142.

It is then emitted to the user via outlet port 150 and the associated passage 152 in mouthpiece 156.

It should be pointed out that similar to the embodi ment previously described, a filter element may be placed in channel 134 which defines passage 140 to trap the condensates and other filterable ingredients.

The unique construction of condenser 116 not only permits this adaptation to a filter element, but further, its design is relatively simple to manufacture compared with other constructions for plural passages. With two flat recessed sides and only one annular recess, it is not a particularly complex machining job to make a finished product.

It is important to point out that the longitudinal spacing of

shoulders

124 and 126 with the opposing semiannular configuration creates the recessed inlet 146 in addition to cooperating with shoulder 114 and the recessed shoulder 112 to appropriately serve as alignment means to indicate proper rotational alignment of condenser 116 within tubular portion 108.
