7 Claims.

My invention relates to smokers pipes, and has for its main object to provide a pipe for smoking tobacco which will eliminate certain well known drawbacks of the present pipes.

As it is known, the smokers pipes used to-day, have a bowl which is lled with tobacco, the top of the tobacco is ignited, and the filling gradually smoked. It is obvious that in this manner, the smoke has to pass through all the tobacco yet unconsumed and laying underneath the burning region or strata, and it is also well known that the smoke passing through the yet unconsumed tobacco will deposit various harmful materials, vapors, etc., so that the tobacco will become wet, soggy, Saturated with various materials, and when burned in such a condition, it will produce an unpleasant and even harmful smoke, and, certainly, the tobacco so contaminated and then smoked, will lose its original fresh taste and aroma.

My invention aims to provide means in a smokers pipe whereby the tobacco will be burned and consumed in successive layers or strata, and the smoke from each layer or region will be directly drawn into and through the stem of the pipe without rst passing through the unconsumed portion of the tobacco. I am aware of the fact that many devices have been proposed for such a purpose, but, to my knowledge, experience and information, none of these devices Were practical, efcient, and desirable, and none of them found their way into actual practice and use.

The main purpose of my invention is to provide a pipe for smoking tobacco, in which the tobacco will be consumed in successive layers, in any desired number, or plurality of stages, without the smoke ever passing through the unconsumed part of the tobacco.

Another object of my invention is to provide means whereby the smoking of the tobacco may be stopped at any stage of the consumption thereof, and the pipe caused to automatically stop operating.

Still a further object of my invention is to provide a smokers pipe, as characterized hereinbefore, in which the smoke will have to pass through quite a complicated devious way, where it will have a chance and means for depositing condensates, vapors, and other harmful ingredients, and wherein it may also be cooled.

Still further objects of my invention will be apparent as the specification of the same proceeds, and, among others, I may mention: to provide a device of the character indicated, which will be simple in construction, easy to operate La and use, will be applicable to pipes used at present, and which may be conveniently removed from the pipe, the same being adapted to be disassembled, cleaned, and just as easily and conveniently replaced into the pipe.

With the above objects in view, my device mainly consists in an upstanding tube placed into the bowl of the pipe, being open at the top, so that the smoke of the burning tobacco may be drawn through the tube without touching the rest of the tobacco underneath the burning region, said tube being slidable downwardly, and thereby causing gradual layers or strata of the tobacco to be burned.

In addition, said tube may be arranged in a self containing unit, easily applied to any pipe, or removed therefrom in order to take apart and clean the same, and just as easily assembled and returned into the pipe, means being provided in said device containing said tube, whereby the smoke is caused to pass through a complicated passageway, which possibly may include receivers or containers for condensates or other deposits, and for cooling the smoke.

In the drawings forming a part of this specification and accompanying the same:

Fig. 1 is a fragmentary sectional elevation showing the bowl of a pipe constructed according to my invention;

Fig. 2 is another sectional View, the section being taken on the line 2-2 of Fig. 1.

Fig. 3 is another fragmentary sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a longitudinal sectional view of a modified embodiment of my invention;

Fig. 5 is a cross sectional view thereof, the section being taken on the line 5-5 of Fig. 4.

Referring now to the drawings more in detail by characters of reference, the numeral I0 indicates my novel pipe, in general, having a bowl I l, and the stem l2, and, obviously, made of any appropriate material, like wood.

The bowl and stem of the pipe may be of any design and construction, entirely as it is usual now, so that my pipe not only may be newly manufactured, but any old pipe may be changed to my novel construction, as will be obvious from the description herein to follow.

In exercising my invention, a screw threaded bore I3 will be made through the bottom of the bowl ll of the pipe shown in Figs. l, 2 and 3, and a screw threaded plug l@ secured therein by the cooperation of their threads, said plug preferably being made of metal, but it can be made of any other appropriate material, as will 3 be obvious. A central sleeve I5 is provided .in the plug member I4, having the aperture or opening I6 therethrough, and a tube or pipe I1, also preferably made of metal, may be pushed into the upper end of said opening I6, the major portion of said tube I1 projecting upwardly in the center of the pipe bowl II. Tube I1 may be closed at the top I8 and said top may be conical, as indicated in Fig.Y 1. Aperturas or smoke inlet holes I 9 are provided around the 'tube I1 near its top.

The plug member I4 may have a depending exteriorly threaded tubular, or hollow cylindrical, downward extension 20,*and-anfapproprately and attractively shaped hollow condensation receiver, and smoke cooler, 2I may be secured "on the depending sleeve by intel-iorly screw threaded upper hollow cylindrical extension 22.

An exteriorly screw threaded inner tube 23 is threaded into the lower part of the tube I1, -it'sflower end passing through a boren :in the lo'enterof the bottom of 'the combustion and .cooler `container :21, and 'terminating in ltne knurled 'disk .or knob. '25, by which it may 'be rotated in said bore or aperture 24.

`Means Amay be provided to prevent yan upward er downwardlmovement ofthe inner tube 23 and pe mit only. its'rotat'ion and, 'as an exampleoi means, a cll'ar26 isi-shown, secured on the ilnerftube "23 right,abovetllie` bottom 'of the conisle'nser container 2l'. r

The use and# operation: obvious from theabove '11d feription, lent'ivvant to offer the following further'explanations and remarks: 'When it i's-'desii'ed-to 'ill the pipe-the knurled knob 25 at the-bottom of my-device, will be rotated in an appropriate direction tlfiere'by causing the outelrtubeffn t moveeupwardlyf, 'as indicated by the 'arrow el, u

"'lh'e tobacco wi'llvfbe lit vand? pipe smoked through the stem I2, vas usual. v'Thepreerraed rrl`e'tllod, however, woi-lf'd be to have fthe tube 1H 'in its l'owest position, llithefbowl "ofthe pifpathen 'mote the tube upwardly through the tobacco. This willf be facilitated "floyf thefp'o'inte'iiL top lof' the tube It will be seen- :that only the `'top layer 33 fof the tobacco will burn,and the Ismoke iroln the stemalrn'ost iin-media-tely,:willJ be drawn through the openings I9 into-`thetube itil, as indicated by the arrow 34. V`'i'he-`sn1ol ethen will go downwardly through the-"tube dil-"then throughrthe inner tube 23, will ei'iit'lfthroil'gh th'elower yopen* ings 21, vas indicated by the fammi/13%, will= go up into the hollow lring 'space'rin-fthe plugA YM and will `exit i-nto the bore f29s-o-the'stem l'l't-hrou-gh the opening 30, indicatedfby 'thea-rr-oW-'l.

It will be seen 'that-not onlyfwillilallthe smoke be` drawn directly- 11"(am=they top" burning yregion 33, but the smoke will al-inost'imm'ediately enter the Ainsideofthe tube-and w'l oid vall y'the 'freshtobacco underneath 'the burningllayerf'or region,

It kwill be seen that not only willal'l 'the smoke be drawn from the burning region directly into the tube I1, but the smoke will pass through a -long, devious passage, having ample chance to v`'deposit all the harmful ingredients therein, and

, will have ample opportunity to be cooled, thereby my pipe produces a cool, harmless smoke, however, will retain all the fresh aroma of the` tobacco without being contaminated by passing through layers of tobacco saturated by vapors, condensations, and deposits of earlier smokes, as is the case lWiththe ordinary pipes usedtoday.

After 4'the region orl-ayerf33 is consumed, `the burning of the tobacco is stopped if no adjusts mentvis inl-ade, so .that my pi-pe will stop `burning at any desired point. If it lis -to vbe smoked through, then the knob 25A will-"be rotated in the opposite directionto lthat used when raisingA 'the tube whereby the interaction ofv the screw threaded tubes 23'and I1 w'illcausethe tube I1 to vmove downwardly va desired distance, asindicated by thel arrow 538. After moving the ytube afpredetermined distance, the 'smoking maybe continued anda secondl'a'yer, let us say the one indicated by the `nurrieral- '39, rwill 'be consumed, and :its smoke, again, will be drawn directly through theaperture's I9' intothe'tube` l1. 'By-a gradual lowering c-'f lthe tube i1, the 'tobacco in thelbowl-of the pipe maybe consinnedfin as many regions, layers, or stages, as desired, until the apertures i9 ofthe-puter tube will' arrive tothe bottom of 'the bowl fI-fl, when, ci course, all `the tobacco in fthe bow-lf wiliihavebeen burned.

It 'also willfbe see-n that at: 11o/point or- 'stage ofthe oi'the tfcbacco'inthe bowl "Ii, will an'yf-smokef-pass through any oi'ft'he lower tobac'cdf-so that-fall ofthe smoke will -be ypr-'ojduc'ed by fresn-tobaccoan'd will'have vitsV ldesi-reelaroma and taste without .being contaminated ib'y 4thev harmful' Vdeposits and ccndensations 'mentioned' hereinbefore-and' well? known top-ipe smokers.

Y

-iSt Yalso 'willi be seen that vmy device may easily bel insta-llediinto `any existing pipe 'bysimply preparing v1ascrew ft-hreafdedbore @l 3v` at lthe bottom thereof 'adaptedto receive "the screw threaded" plug I4 of my device, and that my device 'may be as easily-removed from-fthe pipefbyunscrewingfthe plug-44'. 'The'el-einents -orfparts of Ymy device-may 'thv vbe 'taken "apar-tlby a fewunscrewing. steps, lwhereupon the vbowl of the pipe;

Figsgefand 5 I'-fs'how another embodiment o't my ation. fIn th embodiment, alsoj'the resen'ts they pipe, in general', hav- A plug 40, generally similar to the plug I4, described in the earlier embodiment, may be secured in a bore 4l in the bottom of the bowl, by any appropriate method, as by the screw 4threads 42.

The plug 45, in this case also, may have a depending hollow cylindrical portion 43 with exterior screw threads 44 on which may be secured a cooling and condensation receiving container 45, as by the interior screw threads 45 at its top portion. The plug 4t may have a similar smoke exit opening 39 as described hereinbefore communicating with the bore 29.

In this embodiment, my invention includes a tube or pipe 41 having a preferably conical pointed closed top 48, and a plurality of openings 49, for drawing the smoke from the burning tobacco into the tube, as has been described hereinbefore. The tube may slide upwardly or downwardly, in a sealing manner, in an aperture 55 in the plug 40, and its lower` portion 5l will extend into the space within the hollow plug Aid and the container 45.

A disk 52 may be secured on the lower portion 5I of the tube 4l, said disk having exterior screw threads 53. A wider tube or hollow cylinder 54 may rise from the bottom of the container 45, having the interior screw threads 55 meshing with the screw threads on the disk 52.

A rotatable member 53 may be arranged in the bottom of the container 45, having a knurled operating disk portion 5l, by which it may be rotated, as will be obvious. 'Iwo upstanding rods 58 are secured on the member 55 passing through appropriate holes 55 in the disk 52.

It will be seen that when the knurled knob 51 is rotated in an appropriate direction, it will rotate the disk 52 in the same direction, whereby the disk will move downwardly, as indicated by the arrow Sii, through the operation of the screw threads 53 and 55, and will draw the tube 41 in a downward direction to a desired extent.

The smoke will enter through the apertures 49, as indicated by the arrows 6l, will pass downwardly through the tube 41 into the wider tube o1' hollow cylinder 54, from which it will exit into the container l5 through a plurality of openings or apertures 62, as indicated by arrows 63, after which the smoke will nd its way to the exit opening 30 (arrow 54).

In this embodiment, obviously, the tube 4-1 may be made much narrower than the outer tube I in the earlier modiiication. It also will be obvious that a pipe constructed according to said second modification will be easily taken apart and again assembled, similarly as described in connection with the iirst form of my invention.

In the rst embodiment of my invention, at 15, (Figs. 1 and 3), a pin and slot engagement is shown between the pipe Il and the plug I4, whereby rotation of the pipe is prevented, as will be obvious.

In the second modication, Figs. 4 and 5, the numeral 'll indicates two downwardly projecting pins on the bottom of the disk 52. The purpose of these pins is to provide a limit for the downward movement of the disk whereby the disk must stop at a predetermined distance above the rotating member 56 in the lowest position, so that even in that position, free passage is provided for the smoke to exit through the opening 63.

While I have shown preferred embodiments of my invention, it is to be understood that changes and variations may be resorted to in the elements,

construction or use of my invention, and I reserve my rights to such changes, variations and uses as are within the spirit of this specification and the scope of the claims hereunto appended.
