This lint.ermediate stem diate its ends with baille means comprising the annular flanges I9 and 20 which serve to trap moisture and to direct the course of travel 'of the smoke through the stem in a manner to be hereinafter described.

The annular flanges and the collar portions cooperate to form peripherally disposed annular channels forming smoke compartments.

At the inner end of the mouthpiece I5 there is provided a threaded bushing 2| cooperating with a correspondingly interiorly threaded portion of the passage |51) of said mouthpiece. The bushing 2| has a passage 2 Ia therethrough which is of less diameter than the passage I5b of the mouthpiece. In practice, a plurality of bushings 2|, havin-g passages 2|a of different diameters, may be provided for alternative use to suit the whim of a smoker who may desire to have a pipe which draws more or less freely, depending upon the size of the passage 2|a of the bushing emv ployed.

ber 22 surrounding a portion of the stem member l 'I I. The socket portion I4 of said stern member is'provided with radial openings 23 at a point adjacent the inner end of the mouthpiece I5, through which openings 23 smoke from the superchamber may pass to the passage I5b of said mouthpiece through a bushing 2|, if such be employed.

The inner end of the mouthpiece I5 will extend into the socket portion I4 a distance suilicient to provide adequate space between the inner end of said mouthpiece and the openings 23 in said socket, whereby to permit of adjustment of the bushing 2| toward and away from said openings 23 by turning the head 2| b of said bushing. Thus` the said bushing may be employed to act as a damper for regulating the draft through the mouthpiece I5 by adjustment of the head 2Ib of said bushing toward and away from the openings 23, since the diameter of thehead 2 Ib is substantially the same as, or slightly less than, the inner diameter of the socket portion I4. Hence, if the bushing 2| is unscrewed a few turns so as to move the head 2| b to a position opposite the openings 23, the draft through said openings will be dampened, and, likewise, when the bushing 2| is screwed into the mouthpiece so that the head 2Ib abuts the inner edge thereof, the draft through said openings will be correspondingly increased.

In operation, the sleeve I8 will be positioned as shown in Figure l and the chamber 2 of the bowl I will be loaded' with a quantity of tobacco packed therein against the ange portion 1 which serves to support the tobacco so packed in said bowl.

` As above stated, the space between the circumferential edge of the ange 1 and the adjacent inner wall of the chamber 2 is suflicient to permit smoke from the lighted tobacco to be drawn downwardly and through the passage 9, while at the same time preventing any substantial amount of tobacco from falling below the supporting surface of the flange 1.

As a smoker draws upon the mouthpiece I5, the smoke from the lighted tobacco will pass from the passage 9 through the passage I2 out through the openings I3 into the superchamber 22, and by reason of the inter-position of the anges I9 and 29 substantially all of the smoke will be caused to impinge the inner surface of thesleeve I8 as said smoke passes toward and through the openings 23 of the socket portion I4, and thence through the passage 2Ia of the bushing 2|, and through the passage I5b of the mouthpiece I5 into the mouth of the smoker.

In the process of smoking the pipe embodying the improvements of my invention, moisture condensed out of the tobacco will be trapped upon the upper surface of the flange 1. By reason of the fact that said ilange is made of metal and becomes hot during the process of smoking, moisture so trapped will be dissipated by the heated metal, and consequently Will not get into the passage 9, or if carried into said passage in the form of vapor will subsequently condense in, and adhere to, the walls of the passages 9 and I2 and the inner wall of the ysleeve I8, or said moisture will condense upon the trapping flanges I9 and 28, or the intermediate portion Ila ofthe stem II so that very little, if any, moisture will pass into the mouthpiece I5 to interfere with the enjoyment of the smoker using said pipe. i

If, during `the process of smoking, and without interrupting said process, or disassembling the pipe, it is desired to clean the stem member II, or remove accumulated moisture therefrom, it is only necessary to slide the sleeve I8 to the position shown in Figure 2 to afford ready access to said stem member for this purpose.

It will readily be apparent that when the sleeve member I8 is positioned, as shown in Figure 2, it is a very simple matter to clean the exterior of the stem member II employing a cloth for that purpose and to run a pipe cleaner into the passages I2 and 9 through the openings I3, or even to run the pipe cleaner through the openings 23 without necessitating removal of the pipe from the mouth of the smoker, if desired.

When it is desired to clean the bowl I of the pipe the false bottom 3 may be readily unscrewed to remove the same forfacilitation of such operation as will be apparent.

As seen in Figure 3, I have provided a pipe testing device which may be readily attached to the mouthpiece of the pipe of a type herein referred to. Said testing device comprises a length of rubber tubing, generally indicated at 24, the portion 24a. 0f which may be of somewhat more rigid construction than the inner portionv 24h which is preferably more resilient to enable the same to be fitted over the mouthpiece I5 of a pipe as shown. A thermometer 25, which has had Aits tubular portion inserted through la suitable opening in the portion 24a of the tube 24, has its bulb portion25a positioned interiorly of said tube portion 24a and is more o-r less firmly supported thereby. An auxiliary mouthpiece 28, which may be of a construction similar to the regular mouthpiece I5 of the pipe, is provided for insertion in the outer end of the tube portion 24a. In use, a smoker may readily test the coolness of the smoke which passes through the mouthpiece |5of his pipe by noting the height of the column of mercury in the thermometer 25 as the smoker draws the smoke from said mouthpiece I5 through the rubber tubing 24 and auxiliary mouthpiece 26.

portion, said bowl being provided witha tobacco It will be noted that the bottom surface 4a ofk the base portion lof the removable false bottom 3 is preferably made flat so that the pipe is supported with the bowl I in an upright position as shown in Figure 1 when placed upon a flat surface, such as a table top or the like.

When a pipe constructed as herein disclosed is being smoked, substantially all of the smoke drawn through the stem is caused to impinge theA inner surface ofthe metal sleeve I8. 'I'his result is effected by reason of the interposition of the flanges I9 and 20 which are of a diameter only slightly less than that of the said inner wall of the sleeve. The smoke is compelled to impinge the inner surface of the sleeve in order to p'ass throughvthe small space provided between said sleeve and the. edgesof said flanges. Because of the extended area of this impingement of the smoke with the sleeve, a marked cooling of the smoke drawn through the stem results, since the sleeve'is made of heat conducting material which enables the heat of the smoke to be conducted out of the stemand hence dissipated.

Besides their function just mentioned, the flanges I9 and 20, and, in fact, the entire intermediate portion of the stem, function as filter means to entrap moisture and juices from the tobacco and also to entrap saliva passing from the smokers mouth.

The sleeve I 8 is preferably provided with longitudinal slits I8a at its ends to permit a slight crimping of the ends of the sleeve to enable the same to t more tightly over the' collar portions I6 and I1 when the sleeve'is in the closed {position of Figure 1. Preferably, also, the diameter of the sleeve I8 is gradually diminished from its leftward toward its rightward end having reference to Figures 1 and 2 so that the said leftward end of the sleeve will pass over the collar portion I'I loosely when moved toward and from the position of Figure 2 and both ends of the sleeve will fit snugly on their respective collar portions I6 and I1 when the sleeve is in the position of Figure l.

Having thus described m'y invention, what I claim as new and desire to secure by Letters Patent of the United States is:
