sufliciently simple both in configuration and operation to obvate the objections of users to the complicated manipulations required in the use of devices of the prior art intended for generally similar purposes.

In the accompanying drawings:

Figure 1 is a side view of an illustrative embodiment of the invention;

Figure 2 is a section on line 2 2 of Figure 1;

Figure 3 is a fragmentary section on the same line as Figure 2 with some of the parts in elevation and with a modified baille and holder;

Figure 4 is a perspective of the baffle of Figure 3;

Figure 5 is a vertical section of another modied construction;

Figure 6 is a fragmentary section as on line 6-6 of Figure 5; and

Figure 7 is a perspective view of the baffle of Figures 5 and 6.

In the embodiment of the invention selected for illustration in Figures 1 and 2, the pipe comprises the usual bowl I0 illustrated as of wood and having a shank I2 to receive the stem I4. The stem I4 illustrated is of substantially transfparent plastic material. Such material is available in various colors and shades of which water- White and light amber are very satisfactory. However, for those who prefer not to have the parts inside the stem visible, it is a simple matter to have the stem opaque. I have selected a transparent stem for illustration to facilitate showing the parts inside the stem.

The stem terminates in the usual bit I6 containing the usual smoke outlet I8.I The smoke outlet I8 debouches at its inner end into the enlarged chamber 20. At the bit end of the chamber I provide an aluminum tube 22 embedded at its right end in the material of the stem and terminating short of the baiiie 24 to leave a substantial intervening space. The baffle 24 is a cupshaped member telescoped over and separated from the draft tube 26 which passes through the shank I2 and terminates at the base of the bowl in open communication with the interior of the bowl. In Figures 1 and 2 the baille is provided with three slightly resilient arms 28 shaped at their ends to conform to the outside contour. of the draft tube 26. Thus the baffle is frictionally held in place on the draft tube 26 when the stem and bowl are separated, as for cleaning.

The joint between the stem andr bowl presents serious problems. It must permit easy separation and reassembly of the parts, as the accumulation of condensates in the stem necessitates separation of the parts to discharge the condensate. It must continue to form a liquid tight seal. And over a long period of use including many removals and replacements of the stem, it must continue to maintain sufficient friction to carry the Weight of the bowl while the user is smoking without any danger of separation of the parts and at the same time not tighten up to such an extent as to impede the user inV separating the parts.

In Figure 2 the cupshaped terminal fitting over the end of the shank I2 includes the peripheral flange 30, the cylindrical portion 32, and the flat cap ring 34. This cap is preferably of plastic material of the same general character as the material of the stem, and is accurately fitted to the end of the shank I2. Beyond the cap I provide an annular packing ring 36, and beyond the packing ring I position the holding ring 38 of metal which is drawn .tightly against the packing ring by two woodscrews 40, which screws pass through aligned holes in the ring 38, packing ring 36, and cap ring 34 to enter the body of the shank I2ll After considerable experimentation I have secured best results by using for the packing 36 either Neoprene or -a high quality of natural rubber. The packing ring is iirmly squeezed in place by tightening the woodscrews 40, and its peripheral surface should be painted With glycerin or dusted with line powdered graphite. I have found that the resulting structure resists the action of the liquids accumulating in the stem for an indefinite length of time, and also remains watertight with substantially constant friction throughout the life of an ordinary pipe. The constancy and reliability of the friction may be somewhat improved by forming a rabbet at 42, so that the portion of the packing 36 that actually rubs against the stem I4 has room to eX- pand just a little parallel to the axis of the stem and accommodate itself to the extremely minor changes in the dimensions of the parts resulting from thermal expansion and contraction, and from Wear.

It will be apparent that the products of combustion withdrawn from the bowl I0 through the draft tube 26 will enter the baille 24 and there reverse their direction of motion and pass out between the fingers 28 and into the chamber 20. In practice the chamber 20 encloses a volume of the same order of magnitude as the volume Withdrawn by the smoker in taking a medium sized puff, but in any event the products of combustion remain in the chamber 20 for an appreciable length of time in contact with the outer walls thereof and subject to the cooling action of the relatively thin wall of the stem, which is in turn cooled by contact with the outside air. In this way, without cooling the products of combustion to such a degree as to deprive the smoker of that feeling of warmth which he desires and finds gratifying, cooling of nearly all the products of combustion is accomplished before they leave the chamber 20 to such a temperature that the tarry constituents of the woody fibre which is contained to some extent in even the best tobacco, are effectively changed to liquid form in the chamber 2D and accumulate on the walls of the chamber so that the smoker does not inhale them. It happens that these high boiling point tarry constituents are among the most harmful of the products of combustion in tobacco, physiologically speaking.

The effectiveness of this cooling is such that the user develops materially different habits in smoking. Specifically, instead of filling the bowl completely full and consuming only about 2/3 of the filling, leaving damp, soggy tobacco unburned in the bottom of the pipe to be scraped out before filling again, the user is likely to put somewhat less tobacco in the bowl. And regardless of how much tobacco is in the bowl, the user soon develops the habit of smoking until all the tobacco in the bowl is completely burned. With a mass of unburned tobacco in the bottom of the bowl no bigger than a navy bean, the smoker can still apply a match fiame to that mass and smoke it up without burning his tongue. Thus, after the smoker becomes accustomed to the pipe, he always keeps the heel of the pipe dry and clean. Liquid accumulates in the chamber 2U during the use of the pipe and a careful smoker will remove and empty the pipe after every eight or ten pipefuls. However, the capacity of the chamber is such that from three to five times that much smoking can be done without emptying the stem. And unless and until a careless smoker permits the stem to become at least one-third full of accumulated liquid, there is no practical risk that the smoker will draw any of that liquid into his mouth inadvertently. This contrasts with an ordinary pipe where the accumulation of only six or eight drops of condensate in a wet heel is apt to give the smoker a drink In the embodiment of Figures 3 and 4, the balii-e 4d carries two axially extending prongs 4E, the ends of which engage the plate 38 to position the baffle correctly, and the baffle is held in psition by the friction of oppositely disposed leaf springs 48 bent back from a sleeve 50 permanently assembled on the draft tube 26. Such a construction renders removal and cleaning of the baiile itself easier than with the structures of Figur-es 1 and 2. And when the pipe is in active use, a small proportion of the least volatile constituents of the smoke will condense and accumulate on the inner surface of the baffie, so that about once a month it is desirable to remove the baffle and wipe it clean inside.

Referring now to Figures 5, 6, and 7, the baffle 52 is provided with three diverging prongs 54 for spacing purposes, and the baffle is supported on the draft tube 26 by two leaf springs 56 extending back from the rear edge of the collar 58.

In this embodiment I have indicated a metal cap 60 immediately adjacent the shank 62, and the clearance to secure the best action is obtained by forming a rabbet 64 in the adjacent face of the backing BB instead of having the rabbet in the cap.

In Figure 5 I have also illustrated a stem made up of a small tube 63 within which is fitted a separate bit member 'I0 and the exit tube 'I2 is mounted in the bit li). However, the bit is firmly assembled with the tube 68 in manufacturing the device so that the only separation of the parts by the user is by removal of the entire stem comprising the tube 68, the bit 7U, and outlet tube 'l2 from the remainder of the device.

In the embodiment of Figures 1 and 2, the fingers 28 are first bent outwardly a little beyond the outer surface of the cap 24 to assure that the cap will not be assembled in a stem that does not provide adequate clearance outside the cap. The fingers then extend inwardly into contact with the tube 23 and finally outwardly again at their extreme ends. This last outward extension or curvature affords guidance to the user in assembling the parts and facilitates the initial movement of the cap over the end of the tube. The ends of the :fingers abut the joint structure and act as a stop so that the user will position the cap with its closed end properly spaced from the end of the tube 26.

In the embodiment of Figures 3 and 4 the fingers 48 are provided with a reverse extension 0r curvature at their extreme ends so that the same function of facilitating the initial movement of the cap is secured.

In the embodiment of Figures 5, 6, and '7, the ingers 56 are provided with a reverse extension or curvature at their extreme ends for the same purpose. In the two embodiments last mentioned, the stop function is secured, but not by the same fingers which constitute the resilient support.

Without further elaboration the foregoing will so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service. It will, for instance, be obvious that such springs as 48 in Figure 3, might be mounted on, or made integral with, the ring 38.
