. solaires. (o1. isi- 131) l y The-present invention isy an improvement in 4 and 5 are respectivelyformedat'the'open end smoking pipe Vstructures having incorporated therein membersfor providing a cool, dry and controlled'smoke to the user thereof and is a continuationin .part of mycopending applications [Serial No. 250,220, ledJanuary 10, 1939,

andSerial No. 258,060, led February 23, 1939. It is an object ofthe presentinvention to provide an improved form of pipe structure of a Iii'econtrolled type which is'capable of producinga relativelycool and dry smoke.l

Another object Eof the invention is to provide a'pipestructurevwhich will provide a cool and drysmoke and in which the weight. thereof is retained .to the minimum.

A further and equally important objectof the presentinvention is to provide a commercially `feasible pipe structure vwhich is .capable of pro; ducing a cooled and dried smoke and which can be readily'and'easily disassembled for convenient cleansingthereof.`

A. still-'further object of the present inven` tionis Ito provide an improved means for controllingthering of. thetobacco within a smoking pipe structure.

Further-objects vof the present invention are set forth in the following detailed description of the accompanying drawing, while still further objects of the invention will. be obvious from a consideration' of the present device. ii In the accompanying drawing:

Said `stem 45 9 has an axial bore 34 whose 'cross sectional area at' the smallest pointv thereof is substantially equal to the sum of the cross sectional areas of theopenings I6 oi tube I5.

Mounted within tubell and extending thereacross is a plate I84 whose periphery is formed of a plurality of straight walls I 9 which give said periphery'v a decagon conguration, which is substantially equall in size and similar tothe decagon formed by the walls I I of. tubeql5. A

rectangular opening is formed in the central porl tion of said plate I8.

The rectangular head 29 of a screw section 20. is mounted within the rectangular opening of plate I8 and flattened to rivet the two members to one another. Said screw section 2U is the center member-of a series of telescopic sections 2|-, 22 and 23. Said tubular sections 2|, 22 and 23 have lefthand'thr'eads formed upon their periphery as has said screw section 20. The upper portion of the inner face of each'of said sections 2|, 22 and 23 has lefthand` threads 35 formed thereon with the remaining portions 36 of said inner faces being formed smooth. The threads of screw section 20 are in engagement with the threads 35 of section 2| while, similarly, the peripheral threads of sections 2| and 22 are ref spectively in engagement with the inner threads of sections 22 Vand 23. Section 22 has an annular groove 39 formed at the lower end of its interior face and an outwardly expanding resilient metal ring 33f-is lpositioned within said annular groove 39; The lower end portion' of section 2| is formed solid as at 4|1 with an annular ange 40 formed extending lat right angles' from the upper end thereof a distance sufficient for flange 40 vto at times contact theupper face of ring 33. The lowerk end of screw section y20 and 'section' 22 have annular" flanges v26 extending" substantially atright angles therefrom, whichflanges 26 contact the smooth inner faces 26 'of sections 2| and 23 respectively-while flange III)y of section 2| lwill contact `the wall of the bore ofsection 22. VSection'23 `has an annular flange 24 formed extending from its upper end and which is seated upon the upper-edge of flange lIi. Theperipherylof said section 23 has righthand threads 21 formed at its lower portion, which threads 21 are engaged by threads formed upon ,the inner wall of a cap 30, which cap has a `cavity formed therein whereby the lower portions of screw section 20 an'd `sections 2 I 22 and23 may be receivedy n I5 ,is inserted ,withinjthe b owl3 and over flange face 32 of ring I0. toA gradually'contact the upper face of flange 3|` and with a wedge-like action, forcibly position the lower end of tube I5 about flange 6 and; at the same time, completely seal the interior" ofv tube I5- from the interior of bowl 3except for the openings' I6. n

Screwsection 2.9 is screwed within the'inner threads' 35A of section 2 I.- "Similarly, section 2| is screwedf'within section 22 and section 22 within, 'section' 23 Ring 33 is snappedV into position` within groove 3 9 before said section 2| is screwed into position within the bore of section 22. Plate I8 is then insertedvupon head 29 of section 20 ltubularv member and said head ze flattened to retain pme 'lsY thereon. These coupled members I8, 20,-2I,'22 and 23 are inserted downwardly through bore II` p and the bore of tube I5 until flange 24 Vof section 23 engages theupper end of flange 6 whereby the coupled members arerotatablyl retained within flange 6. At this time, cap 3D is screwed onto section 23 by giving the cap 30 a righthand rotation. Upon edge r33 of cap 30 contacting the bowl 3, the section 23 is retained from upward movement but is at the same time rotatably supported.

'In the operation of the present pipe structure,

ltobacco is inserted withinthe tube I5 and supvported by platev I8 therein. The tobacco is piled I0. By suction being applied `to bore 34 of stem 9, airis drawn inwardly from bore II and upon a flame being applied to the tobacco therein, the tobacco is ignited. Smoke fromtheburning tobacco is drawn through openings 'I6'to within I; I l-Iowever,y only as much smoke as can be drawn lfat a time through bore y34 can, at the same time, be drawn through openings I.6,.due to the similar cross sectional-area of the Vtwo ksets of passageways.

Therefore, the

smoker uponA drawing, draws smoke from within y tubular member I, 'creating a partial vacuum therein which in due time draws the smoke through the openings I6, thereby `assuring'that the tobacco within bore II will vcontinue to burn between draws and also the smoke within tubuing the heavy oils,t\ars rand moistures fromthe smoke, while at the same time, coolingthe smoke.

The burning takes place within the-bore II and, therefore, the heat is retainediwithin this heat insulating chamber, permitting tubular member I to remain cool. As thetobacco is consumed, `additional tobacco is positionedxwithin4 bore II by giving cap 30 |a.righthand rotation which will cause section. 20 and sections 2|, 22 and 23` to unscrew from one anothen'due to section 20 remaining non-rotatable, due to its connection to plate I8. Flanges 26 of said sections 28 and 22 and flange 40 of section12| assure that the sections unscrew in an even manner 'until said flanges 26 `and 40 contact the lower edge of 'n threads 35, whereby further upward movement of plate I8 `is stopped: ASome smokers of the present pipe will find it desirable to maintain the burning portion of the tobacco at the top of ring To return plate I8,cap 30 is given la lefthand.

rotationwhereby the section`s'28, 2|, 22 and v23 will progressively return to the position showny in Fig; lof the draw-ing vFlange 40`of section 2| will contact ringv 33 ofy section 22 whenever said section v22 should inadvertently become stuck and not rotate as desired and will thereby assure that section 22 will return to its closed Y position. Flanges -26 contact thej inner face 31 of cap 35 and thereby maintain thesections at` their innermost position. 4It is obvious that additional members'similar to members 2| or 22 may be included withinv the telescopic sections,

if so desired.

Continued rotation of cap 30run1ocks the telescopic sections from tubular member I and with the unscrewing of ring I2 permits the easy and rapid disassembly of vthe pipe structure whereby it may be conveniently cleansed by boiling in water or otherwise.

The present device is capable of considerable modification, but, however, any such changes as are made to the device shown and described herein which come Within the scope of the appended claims are deemed to be part of the present invention.
