Of the moisture thatcollects in the ordinary straight stem pipe there are two sources, namely, condensation of oily and aqueous vapors in the tobaccoitself and a certain amount of saliva which may enter the mouthpiece. If the saliva be permitted to reach the bottom of the pipe bowl it adversely affects the quality of the smoke. the. other hand, if the natural condensation from the tobacco itself progresses along the pipe stem to the mouth of the smoker it interferes seriously with the enjoyment of the smoke.

This invention aims to prevent either kind of moisture from moving from its source to the oppositeend of the pipe stem. Another advantage arising out of this invention is that the smoke in its travel is caused to traverse a longer path than it does in the ordinary pipe stem and in this longer travel becomes more directly exposed to the cooling action of the atmosphere so that the smoke is actually considerably cooler when received'into the mouth of the user. I

Other objects and advantagesof the invention relating to its functions and maintenance will be more fully set forth hereinafter. In the drawing a preferred embodiment of the invention is shown,the single figure disclosing a pipe made in accordance with this invention and shown in central vertical section.

The illustrated pipe has abowl i, a stem- 2 and a mouthpiece 3 which fits snugly into the end of the stem in the manner illustrated and in accordance with time honored practices in pipe construction. A passage] leading from the mouthpiece through to the bottom of the bowl is also shown, being the usual passage commonly found in pipes of this general character. The stem 2 is provided with an aperture 5 and a second aperture 6, as shown, into which the opposite ends of a tube 1 are thrust, the fit being merely a snug fit which will amply secure the tube in position and yet permit its removal with reasonable convenience. The end 8 of the tube terminates in full communication with the passage 4, the boring of the hole 5 being continued until such full communication is attained. Yet the end 8 of the tube does not obstruct the passage.

The other end 9 of the tube sets down into the passage 6 and is notched out at II on that half of the tube which faces towardthebowl so that smoke from the bowl may flow-into and up through the tube. The extremity I2 of the tube extends into the recess H in the bottom of, the bore 6 and blocks the passage 4 so that neither smoke nor moisture may flow straight through the passage 4 in the pipe stem. The smoke must detour through the tube 1 while the condensation coming from the bowl will bedeposited in the recess l3 and in the pipe stem between that point and the bottom of the bowl. The vertical wall of the end 9 of the tube will act asacon densing surface, particularly by reason of the fact that any heat imparted thereto by the smoke will be dissipated by conduction rapidly up to the top of the U-shaped tube, thence intothe atmosphere. v

Saliva entering the mouthpiecal of course, cannot fiow through the tube, and will be stopped in the passage by the extremity I2 of the tube. It may, of course, collect in the pas sagebetween the apertures 5 and 6,'which space serves as a reservoir and saves the smoke from passing through such accumulated moisture. The U-shaped tube m'ay readily be removed from the pipe stem and cleaned with an ordinary flexible pipe cleaner and at the same time the horizontal passage 4 may be "cleaned 'in the usual manner with a pipe cleaner. The holes 5 and 6, which may be straight sided or tapered, 30 after removal of the U-shaped tube may be cleaned easily with wads of cotton or paper. There being no sharp bendsin' the tube it-can be readily cleaned with the well known cotton covered flexible wire pipe cleaners. Thus no dimculty will be experienced in keeping-the entire pipe perfectly clean.)

It will be apparentthat the tube 1 may be used with curved stems aswell as. straight stems' The tube 1, by reason of. its position, shape and size, makes'it convenient'for'the userto slip a finger between the legs of the tube and. .thus readily hold the pipe on the one finger alone. He can then use the other four fingers on his hand for handling whatever tools,books or papers may be engaginghis attention at the time. Therefore, when this feature of the invention is desired to beused the shape of the space between the legs of the tube will be dimensioned so that the finger of the user may be wedged snugly therein. v

The material from which the tube is made may be steel,. aluminum or other appropriate metal easily fabricated into the shape shown or it may be a'hard rubber composition, Bakelite? sage therethrough connected with the bottom of the bowl, and a removable U-shaped tube hav ing one open end communicating with said pas sage without blocking the same and the other end communicating with the passage, by means of an opening facing toward the bowl, a part of the wall of said tube being positioned. to seal said passage between said opening and the mouthpiece, said passage being wholly unobstrncted'between the bowl andits openend'exeept by said'wall.

2. A.;tpipe including a bowl, stem and 'mouthpiece, a passage. extending directly through the mouthpiece and stem into said-bowl, and a removable U -shaped tube piercing thestem at the top side thereof communicating with said passage-fit two longitudinallyseparated points, the end of the tube nearest the mouthpiececpening into the passage without'obstructing the same while the other end nearer the bowl communicates'with the passage only toward the bowl and has a wallintersecting the passage to seal 3 s m Said passage being wholly unobstructed betweenthe. bowliandits open end except by wall.

3. A pipe including a bowl and stem, the latter being provided with a passage extending from: the bowl tothefree end of the stem, a removable U- -shapedtube entering the stem, from the-topside thereof through two spaced apart apertures, said apertures being provided in the.

stem extending upwardly fromv said passage and sufliciently spaced apart that the legs of the tube'eonnecting them affords a space for insertion of a finger the end of the tube nearest the bowl having a wall portion intersecting and obstructing thefpassage on the side toward the freeend of the stem, the same end of the tube beingnotched to affordcommunicationv with the passage; in the direction toward the bowl, the other-end of the tubefreely communicating with the passage nearer the free end of the stem without obstructing the same, said passage being wholly unobstructed between the bowl and its open end except by said wall.

4. A' pipe including a bowl and stem provided I with a passage extending from the bowl longinearest the bowl.

V 5. A pipe including a bowl, stem and mouthpiece provided witha passage extending from bowl longitudinally through said stemand mouthpiece, spaced apart apertures being provided in said stem leading from said passage upwardly through the top surface of the stem and in open communication with said passage, and a U-shaped7 its ends snuglybnt 'reincvably fitted into mid-apertures, the tube 'end'ren'rote from the bowl communicating with the passage without obstructingfit, the' end nearest the having a wall portion thereof traversing lndsmliing said passage between the two apertures" and being notched to establish communication 1mm the bowl throughihe passagethence the tubeto the mouthpiece, said: passage through the stem being whollyunobstructed'except by a wall portion of the tube end nearest the'bowL. T 6. A pipe including abowl, stem and mouthpiece and having a passage extending from we bowl direct-1y throughisai-d stem and mouthpieca ami a U-shaped tube piercing-the stem from the top side thereof downwardly into saidpassage, the tube end nearest the mouthpiece communicating withthe passage but not obstructing it while the end nearest the bowi has a depending wall sealing the passage, and is notched toestablish com-- munication from the bowl through andtube to the mouthpiece.

7. A pipe including 'a bowl, stem'and mouth-' piece andhaving a passage extending from the bowl directly through said stem and'mouthpicce; and a U-shape'd' tube having its ends" piercing the stem from the top side thereof downwardly into said passage, the tube end nearest the'mouthpiece communicating with the passage but not obstructing it, the tube end nearest the bowl being provided with means sealing the passage in a direction extending toward the mouthpiece while aii'ord'ing; communication from the tube into the passage toward and'into" said bowl, the passage being unobstructed betweenthe bowl and mouthpiece except by said means, the tube and said means thereon being bodily removable from the stem to completely open said passage for clean:
