Claims. 1

The present invention relates to asmoking device and more specifically to a pipe provided with a trap and cooling means. i

It is recognized that the incorporation of a trap and cooling means in a pipe is not broadly new and that-many pipes have been oifered for commercial sale which include this feature. However so far as the applicant is aware such pipes have not met with commercial success for several reasons. Probably the primary reason are that the traps have been so constructed that the pipes are diflicult to draw and in addition the physical balance of the pipe ha been upset. Another reason has been the diificulty of cleaning and a still further reason has been the cost of manufacture which has made the inclusion of traps in low cost pipes prohibitive.

The object of the present invention i to provide a pipe having a trap and cooling meansand wherein the undesirable features enumerated above are eliminated. This and other objects will become apparent upon a consideration of the invention hereinafter described with particular reference to the accompanying drawings wherein:

, Fig. 1 is a perspective of one embodiment of the invention,

Fig. 2 is an exploded View ofthe embodiment of Fig. 1, i

Fig. 3 is an exploded cross sectional view taken vertically through the embodiment of Fig. 1,

Fig. 4 is a fragmentary view enlarged to show the trap in supported position,

Fig. 5 is a perspective view of another embodiment and Fig. 6 is an exploded perspective view of the embodiment of Fig. 5.

Referring to the drawings and more particularly to Figs. 1 to 4., it will be seen that the pipe includes a bowl A, and stem B, the latter including a part ill integral with. the bowl and a removable mouthpiece I2.

The bowl A has the usual tobacco receiving recess l4, and forward thereof the outer peripheral surface of the bowl opposite the stem is cut to provide a positioning faceportion l8 and side fins 2.0 which co-operate with the face I8 to form an outwardly facing channel 2 l. Instead of the con ventional passage or duct from the tobacco receiving recess 14 through the stern the pine herein is provided with a short passage or duct 75.2 and a long passage or duct 2 each having one end opening into the face 88. As best seen in Fig. 3 the short passage 22 terminates in the tobacco receiving recess 14 whereas the long passage 24 extends the entire length of the bowl and stem with its opposite end opening in the mouthpiece portion [2.

With the body of the pipe so constructed the channel 2| is adapted to receive a hollow chamber member 26 here shown as a rectangular box having a rear positionin iace 28, front face 30, Side wall 32 and top and bottom walls 34. The dimensions of the member 26 are such that it nests in the channel 21' and the side walls within the fins 28 thus retaining the symmetry of the bowl with the face 28 in co-operating relationship with theface l8.

The chamber member 26 further includes anintcrnal inlet passage and an internal outletgpassage, the former being a conduit or tubular element 42 having one end secured in the face 28 and its other end terminating adjacent the lower end of the chamber and the latter a vertical conduit or tubular element 44 also having a horizontal portion secured to the face 28. The upper end of member 44 terminates at a point above the inlet passage and preferably adjacent the pper end of the chamber member 26. I

Aligned with each of the conduits and secured to the outer side of face 23 are a pair of nipples 46 and 48 the former constituting an extension of conduit #2 and "the latter of conduit '44. These nipples are so positioned that they telescope respectively into passages 22 and 24 of the bowl and function to position the trap chamber in place and secure it removably to the bowl (see Fig. 4)

With the pipe so constructed it will be seen that upon drawing on the stem the smoke will be drawn from the tobacco receiving recess through passage 22, nipple 4G and conduit 42 into] the chamber where the impurities will drop out. Thereafter the smoke will rise and be withdrawn from. the chamber through conduit 44, nipple M and .stempassage 24.

With the foregoing construction it will be seen that there is provided a relative large chamber which holds a substantial quantity of smoke. When filled, the smoke is initially chilled providing a cool smoke and to increase this chilling effect faces is and 28 may be slightly separated by spacers fi'lto provide an air space therebe" tween. Moreover by having a relative large chamber with a separate inlet and outlet passage no resistance to the draw occurs as happens when a labyrinth passage-is used. It should also be noted that the chamber is readily removable permitting ready cleaning, as by boiling. When made of light metal or plastic the trap can be constructed so inexpensively as to permit its being discarded and replaced. However when it is made of an expensive material and it is desired to clean it the bottom wall 3e may have a removable plug 56 aligned with conduit 44 and having its upper end close an opening in the lower end of the conduit whereby when removed a wire or the like may be inserted for cleaning purposes. When the trap member is removed the passages 22 and 24 may also be readily cleaned.

However one of the distinct advantages of constructing the trap in the manner described is that the balance of the pipe may be maintained as the chamber may have a weight equivalent to that of the material removed from the bowl thus maintaining an accurate relationship between the bowl and stem.

Referring to the embodiment in Fig. 5, the structure is like that previously described except as herein indicated. The bowl A is shown as being generally circular witha crescent cutout forming a convex positioning face 6!! and the chamber member 62 is also in the shape ofa crescent having a concave positioning face 64 to co-operate with the face of the bowl. In addition the bowl is provided with a circumferential groove 68 for receiving an elastic member to secured to the side edges of the chamber member.

, From the foregoing it will be seen that the pipe maybe readily and inexpensively manufactured as it is not necessary to finish the parts to extreme accuracy, yet a symmetrical and finely balanced pipe is obtained.

As many changes and diiferent embodiments of this invention could be made without departing from the scope thereof it is intended that all matter contained in the above description or shown in the drawings be constructed as broadly showing and describing the invention and notin a limiting sense.
