use and has for its object to provide an 1mproved construction -for a pipe whereby any` obstruction atthe bottom of the bowl at its junction with the smoke passage may, be easily, quickly and positively removed. A further but subsidiary object of the invention is to provide a device, permanently associated with or carried by the pipe, which may be used in coperation with the improved structural features ofthe pipe proper to secure the result specified.

One of the problems of the pipe user is to: revent` clogging or stoppage of the pipe owl and bore or smoke passage, especially where the latter enters the former, thereby insuring that the pipe shall .draw well, and various constructions have been suggested to realize this ideal in greater or less degree. Others again have not attempted to prevent the diiiiculty but have directed their efforts t0 providing a Way for effectively clearing the pipe when obstruction has taken place.

My invention, herein to be described, be-

longs to the last class rather than to the It is a matter of common experience with pipe smokers that a pipe soon tends to clog at the bottom of the bowl at the point where the stem bore or smoke passage enters. The material which does, the clogging is a mixture of tobacco and ash more or less saturated with saliva and nicotine, and takes the form of a hard baked mass called dottle This dottle usually occupies the bottom of the pipe bowl at the point mentioned and extends up into the bore of the pipe for a short distance, thereby becoming, so to speak, locked into place.

To remove this dottle the smoker thrusts a pipe cleaner, wire, hat or hair pin, or similar device, down the smoke passage into the bowl. Even when these devices are at hand their use is disagreeable and dirty. More commonly, the smoker inserts a knife blade into the bowl and endeavors to push the dottle away with the knife point.

Application led April 26, 1917. Serial No. 164,600.

' with; Fig. 3 represents a section taken along the line 3--3 of Fig. 1; Figs. 4 and 5 represent views, similar respectively to Figs. 5 and 4, of a pipe provided with a modified form o-f my invention; and Fig. 6 represents a section taken along the line 6-6 of Fig. 4. p In the drawings, which show (referring particularly to Figs. 1 to 3) the application of my invention toa very usual form of briar pipe, 1 denotes the bowl of the pipe and 2 a'short shank integrally united to the.

b owl and having a smoke passage or bore 3 opening into the bottom of the bowl at one side as at 4. The usual bit 5, of greater or less length, is fitted to the' outer end of the stem.

The shank 2, on its bottom adjacent to the bowl, is preferably scooped out or recessed, as shown at 6. Preferably this recess is given the form of a transversecylindrical segment. They recess also referably does not extend to or open directly into the bore 3. From the top of the recess a short straight passage 7 connects with the end of bore 3 as it opens into the pipe bowl.

A metal sleeve 8 having an opening 9 is mounted upon the shank 2 adjacent to the bowl, being preferably fitted upon an inner bearing sleeve 8 having flanged ends, and is adapted to be rotated to bring the opening either in or out of registry with the recess 6. The flanged bearingsleeve 8 must, of course,

itself have an opening in registry with the y recess 6.

The sleeve 8, diametrally opposite openbe finished in any desired way, as, by plating, or may be of gold, silver, or other metal.

They may, therefore, be made to add to the finish and richness of the pipe as a whole. In use, should a dottle form in the usual lWay, the sleeve '8 is turned ,thumb until the opening 9 is in registry by linger and with'the recess 6. The pin 11 is then withdrawn by the aid of head 12 and thrust up through the passage 7 thereby dislodging the shorter than the inner bearing sleeve 8. The

l passage 7 is continued along the bottom of within the sco e of the invention and of the the stem as an open slot and the bearing sleeve is also provided with a slot in registry therewith. The pin 11 has its outer end fixed in the sleeve 8 and passes through the slot in the bearing sleeve and into passage 7 'where it normally lies in the position shown in Fig. 4 with its inner end just 1nside the smoke passage adjacent to the bowl. Preferably this inner end is provided with a Small ball tip.

By sliding sleeve 8 tow-ard the bowl, the pin 11 will be thrust upwardly through the passage 7 so as to push the dottle into the bowl in the same manner as has been previously-described in the oase of the pipe shown in Figs. 1 to 3. Pin .11, lying permanently in the passage 7 serves as a feather to prevent the sleeve 8 from rotating upon its bearing sleeve.

Various changes in detail may be made claims which ollow and will .be obvious to those skilled in the art. Thus the sleeve 8,.

instead of being arranged rotatably, as shown, may be made to move axially so as to uncover theirecess 6 when desired, the opening 9 being omitted; the bearing sleeve 8 would, in such case, have to be made longer, of course, or other ways of o ening or closing the recess 6 and passage may be employed.-

The recess 6 may be omitted altogether, if desired, letting the passage 7, in such case, extend clear through to the outer surface of the shank.

And, of course, any pin or slender stick such as a match stick or the like, may be substituted for the pin 10.

The cleanincgl passage 7, being downwardly directe serves also as a drainage well for the `fluid saliva residues and the like which usually collect inthe bottom of the bowl. This residue may be removed altogether bymoving the sleeve 8 so as to open the cleaning passage exteriorly and this .removal may then be facilitated by blowing into the upper end of the smoke passage while the open ,end of the bowl is closed bythe palm of the hand.

The adaptation 4of my invention to other forms of pipes will be obvious to those -skilled in the art.

- Ibowl, said cleaning edto be Having described my invention I claim:

1. As a new article of manu acture, a smokers pipe comprising a b owl and shank portion joined thereto, the latter having both the usual smoke passage and a cleaning passage leading upwardly to enter the smoke passage adjacent its opening into the bowl, said cleanin passage beingdirected so that a match stlck entered therethrough will act to` loosen the dottle and' thrust it into thebowl.

2. As a new article of manufacture, a, smokers pipe comprising a bowl and an in-v tgral shank portion, the latter having both the usual smoke passage and a cleaning passage leading upwardly to enter the. smoke passage adjacent its opening into the passage being directed so that a match stick entered therethrough will act to loosen the ottle and thrust it into the bowl.

3. As a new article of manufacture, a smokers ipe comprising a bowl and shank portion joined thereto, said shank being provided with two independent passages which open into the l.bowl at a common point, the outlet of one passage being at the outer end of the shank whereby a smoke passage is-formed and the outlet of the other passage being at the bottom of the shank wherebyv a cleaning passage is formed adapted to be entered by a match stick so as to loosen and thrust the dottle into the bowl.

4. As a new article of manufacture, a smokers pipe comprising a bowl and shank portion joined thereto, said shank being provided with two independent passages which opcn into the bowl at a .common point, the outlet of one passage being at the outer end ofthe shank whereby a smoke passage is formed, and the outletofthe other passage being at the bottom of the shank whereby a cleaning passage is formed 5. As a new article of manufacture, a
