'I'he sleeve is of a length to extend into the bore of the barrel beyond the rear limits of the smoke port thereto and in its upper wall, circumferentially aligned with a pointer 2|' of the head 2|, is formed with a longitudinal depression providing a smoke channel A22 which opens into the interior of the plug through a narrow throat 23 disposed adiacent the base or head wall of the plug. It will be readily apparent that the described smoke channel serves to deect the gases of combustion to direct the same against the head` wall, the non-conductive nature of which prevents transmission of heat to the knu'rled edge. The plug of course serves as a valve in response to rotary movementI thereof for sealing the condensation chamber of the barrel against escape of liquid deposits through. the smoke port into the bowl of the pipe a provision which permits the pipe to be safely carried in the pocket when not in use.l

The modification shown in Figs. 5 and 6 represents a metal extension 25 fixed to the mouthpiece and in the assembled position of the latter arranged to snugly it the wall of the barrel for the greater portion'of the barrel length, the forward end of this extension being depressed in the provision of a smoke channel 2B corresponding to the smoke channel 22. Lateral wings 21 are formed at each side of the depressed channel in the transverse plane of the smoke port and functionally correspond to the concentric wall of the plug for lapping the smoke port in response to rotary movement of the mouth-piece.

' The invention is believed clear from the foregoing description, it being considered obvious that structural modificationsother than those illustrated may be resorted to without departing from the scope of the invention. I intend that the language employed in the hereto annexed claims be given an interpretation commensurate with the state oi' my advanced teachings and that no limitations be implied excepting where such limitations are necessarily introduced to the claims to distinguish from prior knowledge in the art.

What I claim, is:

1. In a tobacco pipe, in combination, a ba rel formed-with-a through-bore operating as a condensation chamber for the gases of combustion, having a smoke port in the upper Wall, and providing a tobacco-receiving chamber arranged in smoke-feeding relation to the smoke port, and

removable closure devices for the opposite ends of said bore, one of said closure devices providing an extension projecting into the bore and into lapping relation to the smoke port to act as a valve therefor, said extension providing'a smoke conduit movable by rotation into registering relation with the smoke port and operating to'divert smoke drawn through the lattervinto the forward end of the condensation chamber for causing said smoke to traverse a circuitous route in its passage through the chamber.

2. In a 'tobacco-pipe, in combination, a barrel formed with a through-bore operating as a condensation chamber for the -gases of combustion and -having a smoke port in the upper wall. a tobacco-receiving bowl detachably mounted on the barrel in smoke-feeding relation to the smoke port, a removable plug operating as a closure for aaooas- Y fthe front end o: the bore, a mouth-piece detach.

ably ntting thev rear extension carried lby end of the bore, and an the mouth-piece and ex'- `tending forwardly 'therefrom into, l" pping rela .tion to the smoke. port; the lapping portion of said extension having a channel-forming depression therein movable by rotationv relation with the smokeport andv operating to divert smoke drawn through the port into the forward end of the condensation 'chamber for causing said smoke to traverse a circuitous route in its passage to themouth-piece.

3. In a tobacco pipe, in combination, a barrel formed with a through-bore operating as a condensation chamber for the gases of combustion and having a smoke port inthe upper wall, a tobacco-receiving bowl mounted on the' barinto registering rel in smoke-feeding relation to the smoke port, 4

a mouth-piece detachably fitting' the rear end of the bore, and a removable plug operating as a closure for the front end of the bore and formed with an extensie projecting rearwardly therein beyond the smoke port, said extension having a snug t in relation to the wall of the bore modified by a channel-forming depression arranged to register with the port and operating to divert `smoke drawn through the port into the forward end of the condensation chamber for causing said smoke t6 traverse a circuitous route in its passage to the mouth-piece.

4'. In a tobacco pipe, in combination, a barrel produced from a metal conducive to the radiation of heat and formed Awith a through-bore operating as a radiation chamber and having'a smoke port in the upper wall, a tobacco-receiving p bowl detachably mounted on the barrel in smokefeeding relation to the smoke-port, a mouth-piece detachably fitting the rear end of the bore, and a rotary plug operating as a closure for the front end of the bore and formed to extend rearwardly therein beyond the smoke port, said extended portion of the plug having a snug iivt in relation to the wall of the bore modified by a longitudinal depression movable byrotation into and from registering .relation with the port and operating in its-registering position as a smoke channel to divert'smoke drawnv through the port into the forward end of the radiation chamber for causing said smoke to 'traverse a circuitous route in its passage to the mouth-piece.,

5. 'Ihe tobacco pipe defined in claim 4 wherein the .plug is thimble-'like in form and of two-piece construction of which the head wall is of Bakelite or other like or suitable material resistant to the conduction of heat.

6. In a tobacco pipe, in combination, a thinwalled barrel produced from a metal conducive to the radiation of heat with a through-bore of ,appreciable volumetric capacity operating as av condensation chamber for the gases of combustion and having a smoke port in the upper wall, a tobacco-receiving bowl mounted on the barrel in smoke-feeding relation to the smoke port, a mouth-piece seating in the rear end of the bore and rotatable in relationl thereto, a closure device ping condensations within the condensation u port to the tobacco bowl.

'7. In a tobacco pipe, in combination, a barrel bored to form a condensation chamber for thegases of combustion and having a smoke port in the upper wall, a tobacco-receiving bowl mounted on the barrel in smoke-feeding relation to the smoke port, a mouth-piece detachably associated with the barrel, and an extension carried by the mouth-piece and extending therefrom longitudinally of the bore into 'lapping relation to the smoke port, the lapping portion of said extension having a channel-formingdepression therein movable by rotation into registering relation with the smoke port and functioning, when so registered, to divert smoke drawn through the port into thefgforward end of the condensation chamber iorcausing said smoke to traverse a circuitous routein its passage to the mouth-piece.

8. In a tobacco pipe, in combination, a barrel formed with a through-bore operating as a condensation chamber for the gases of combustion, having a smoke port in the upper wall, and providing a tobacco-receiving chamber arranged in smoke-feeding relation to the` smoke port, a mouth-piece functioning as a removable closure for -one end of said bore, and a removable closure for the other end of the bore, one of said closures providing an extension projecting into the bore and into lapping relation` to the smoke port to act as a valve therefor, said extension providing a smoke conduit movable by rotation into registering relation with the smoke port and operating to divert smoke drawn rectvely from the point of entry of said smoke to the mouth-piece for causing the smoke to traverse a circuitous route in its passage through the chamber.

i`9 Tn a tobacco pipe, in combination; a barrel kformed with a through-bore operating as a condensation chamber for the gases o f combustion, having a smoke port in the upper wall, and providing a tobacco-receiving chamber arranged inl smoke-feeding relation to the smoke port, a mouth-piece seating in the rear end of the bore and rotatable in relation thereto, a closure device detaehably fitting lthe forward end of the bore, and a thin-gauge metallic device for the. smoke port flxedly carried by the mouth-piece and extending therefrom as a valve for the smoke port into the bore of the barrel, said valve device being movable by rotary movement of the mouthpiece from a n ormal position inoperative to thev smoke port into closure relation thereto for trapping condensations within the condensation chamber against admission through the smoke port to the tobacco-receiving chamber.
