' UNITED STATES PATENT vori-ica` ARTHUR B.. MODINE, OF RACINE, WISCONSIN.

` TOBACCO PIPE.

.I'Application led December 6, 1923. Serial No. 678,901.

To all 'whom it concerne.;I f y Be it known that I, ARTHUR M onrnma citizen of the` United States, residing at Racine, in the county of Racine and State of VViscons-in, have invented certain Vnew and useful Improvements 1n Tobacco Pipes, of whlch the followmg is a description.'

My invention relates to improvements intobacco pipes, and more particularly vto a pipe having means. for cooling the smoke.

passing therethrough so as to render the same most pleasmg to thetaste,and prevent burning of the tongue and mouth.

The invention has among its objects the'.

production of a device of the kind described, which is simple, convenient, com.-V

pact, durable, reliable, satisfactoryv and efficient for use wherever found applicable.

Many l)ther objects and advantages of the construction herein shown and described will. be obvious to those skilled'in theV art from the disclosures herein given.

To this end my invention consists ingtlhe' novel construction, arrangement yand .coinbination of parts herein shown and i' de scribed, and more particularly pointed out in the claims. I

In the drawings, wherein like referenc characters indicate like or corresponding parts,

Y Fig. 1 is a longitudinal sectional lviewl taken through one form of my device; y

Fig. 2 is a similar View showing a modified form;- Y

Fig. 3 is a section taken on the line 3-3 of Fig. 2; and Y Fig. 4 is a section showing another modified form.

In the drawings, wherein Ivhave illustrated the preferred embodiments'of my invention, there is shown in Fig. 1 a pipe' having ar bowl 1 hollowed out as at 2 to provide a tobacco-receiving chamber and Vhaving passages 5 and 6 leading from said chamber to the exterior of the bowl. Thepassage 5 is substantially at the extreme bottom of the chamber, while the passage 6 is at a'higher elevation. A stem 3 having a rather large bore 7 therethrough from one end,i`s fastened to the bowl and has a pair of openings 5 and 6 through one end, to register with the openings 5 and 6 through the bowl.

A mouthpiece 4: is removably fitted to the open end of the stem 3 and has a draft passage S therethrough from end to end,

. said passage extending obliquely downoccurs those irritating noises or wardly from adjacent the upper end of that portion of the mouthpiece that enters the bore 7 of the stem. p

In order lto cool the smoke passing through the pipe, the stem is preferably made of metal andhas ribs or fins 9 extend- .ing about its periphery, so that these fins may serve to carry off and radiate or dis- -sipate the heatl from the smoke passing through thek stem. The capacity of the chamber 7 is vmade sufficiently large so that it will hold a substantially full puff of smoke so as to give the smoke a chance to have its heaty absorbed or radiated before .passing through the mouthpiece 4.

'In order to agitate the smoke passing through the cooling member and absorb :or dissipate substantially all of the heat therefrom, a spiral member or vane 10 is arranged in the chamber 7 so that the smoke passing'through the chamber will be conducted along a` spiral path so that all of it will engage the wall of the stem 3.

The

spiral member 10 is preferably secured tov the mouthpiece 4 so that when the mouthpiece is removed the spiral member may. act. as a scraper to clean the stem 3.

In smoking a pipe, the bottom of the vbowl generally in time lls up with tobacco andjmoisture making a gummy or partly liquid substance, which I term the -slug, and it is sometimes difficult to prevent drawing particles of this slug up through the mouthpiece when smoking the pipe. It is on account of this slug that there commonly urgling. In use, the pipe is generally heb? so that thev bowl is below the smokers mouth and therefore, when using a pipe of my con'- struction, even though there is a slug at the bottom of the bowl, the smoke Willpass. through the upper port 6, moving spirally through the stem, and thence through the mouthpiece. Any nicotine, vapors, or tobacco oils impinge on the walls of the stem and spiral member, where they may con- ;dense and flow back into the bowl through the lower duct 5. It is to aid in this purpose that the draft passage 8 is formed in the manner shown, that is, one end of the same communicates with the stem at` the upper part of the stem rather than at the center or bottom thereof.

In the form shown in Figs. 2 and 3, ithe stem part 11 has a draft' passage 12 therethrough lin registry with and of the same wound a metallic member having one flange which lies against the periphery of the stem and the other flange or rib 17 extending laterally of the stem and conducting the heat away therefrom.

Thus it is seen that I have provided a pipe in which the smoke is cooled during its passage through the stem and in which any of the va ors or oils will be condensed when passing this cooling means, so that only the cool, dry smoke will be taken up by the smoker. y

Having thus described my invention. it is obvious that various immaterial modifications may be made in the same without de' parting from the spirit of my invention, ience I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein -shown and described or uses mentioned.

Vhat I claim as new and desire to secure by Letters Patent is:

1. A tobacco pipe comprising a bowl, a metallic stem having tins for radiating the heat therefrom, and means for swirling the smoke outwardly against said stem during its passage therethrough.

2. A tobacco pipe comprising a bowl, a metallic stem communicating therewith adjacent the bottom thereof,V and having integral Iins thereon for radiating the heat of the smoke passing through the same, and a spiral vane extending longitudinally through said stem and swirling the smoke outwardly during its passage through said stem.

3. A tobacco pipe comprising a bowl, a tubula'r metallic stem part with an enlarged bore therethrough, fins formed) inte ral with the stem for radiating the heat of t e smoke passing through the same, a mouthpiece extending from said stem and having its bore 'downwardly inclined from the top of said stem, said bowl having openings into said stem adjacent the bottom and' top of the bore through the stem.

4. A tobacco pipe comprising a bowl, a tubular metallic stem with an enlarged bore therein. tins formed integral with the stem for radiating the heat of the smoke passing through the same, u spiral vane lextending longitudinally through the stem for swirling the smoke outwardly during its passage through said stem, and a mouthpiece extending from said stem and having itsv bore communicating directly with the upper part of said enlarged bore, said bowl having openings into said stem adjacent the bottom and top of the enlarged bore through the stem.

In testimony whereof, I have hereunto signed my name.
