Be `it known lthat HARRY Lrioricmr,` .la citizen ofthe UnitedStates, residingzatfGouncil Bluffs, `:in fthe, county of. Pottawatt-amie Yand State-,of Iowa, has invented certain new :and vuseful.Improvements in Pipes,-of which-.the following is Va specification, reference being hadtherein to the accompaniyingE drawings.

The invention relates to pipes, and f-hasfor its'objectzto prov-idea device of this character, the bowl of which has its upper edge provided with downwardly and inclined apertures terminating in the chamber of the bowl at points spaced fro-m the upper and lower end of the chamber and forming means for supplying cool air to smoke below the cinders of the tobacco and abo-ve the bottom moist end of the tobacco, thereby obviating burning of the tongue or mouth as is now the common dilliculty with conventional forms of pipes.

A further object is to provide the upper end of the pipe bowl with a rotatable channeled annular member having one of its flanges overlying the upper end ofthe bowl and its lower flange disposed in an annular groove in the outer periphery of the bowl, said upper flange being provided with apertures adapted to register with the apertures in the bowl, and to regulate the amount of air admitted upon a rotatable adjustment of the -annular channeled member.

A further object is to provide the ends of the stein of the pipe with an annular disposed aperture for admitting'air direct to the smokers mouth for additionally cooling the smoke.

l/Vith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the preoise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit ofthe invention.

In the drawing Figure 1 is a perspe-ctive view of a convene tional form of pipe showing the device applied thereto.

Figure 2 is a 'vertical longitudinal seetional view through the pipe bowl and la portion of the shank thereof.

Figure 3 is a horizontal sectional view throughfoiie iend; of thestemF showing :additionalairholes. n C

Referring to .the drawingnthe numeral 1 .designates the bowl' of the fpip e,.2-the 'shank .and `the iremovableistem carried thereby, 5Pipes as at ,presentconstructedand usedare objectionable .in that ythe bot Tsmokei'enters the .smokers mouth,-.1and yoften 4irrita-tes the membranesof the mouth or :burns the tongue. i

.To obviate thi s difficulty the fbofwl l .of "the pipe is provided with a plurality of downwardly and inwardly inclined apertures 4, which extend downwardly from the upper end 5 thereof and terminate at 6 spaced from the upper and lower ends of the chamber 7 of the bowl, and through which apertures cool -air passes, and mixes with the smoke, below the fire within the pipe, consequently the smoke is cooled before it enters the smokers mouth. By terminating the lower ends 6 of the apertures 4 above the lower end of the chamber V7, it will be seen that they are abo-ve tobacco which would become soggy, incident to saliva which flows through the smoke passage 8, and consequently will not become clogged.

Rotatably mounted on the upper end of the bowl 1 is a channeled annular member 9, which member is provided with a horizontally disposed annular flange 10, which registers with the upper end 5 of the bowl, and is provided with a plurality ofapertures 11, which normally registerwith the upper ends of the smoke passages 4, and it will be seen that by rotating the yannular member 9 slightly, the amountof air allowed to pass through the air apertures 4 may be regulated, which is particularly advantageous ac cording to the kind of tobacco being used. The annular member 9 has its flange 12 disposed in an annular groove 13 in the outer periphery of the bowl 1, therefore the annu-l lar member is securely held on the bowl. Flange 12 may be crimped or forced into the groove 13 in a conventional form of press, therefore it will be seen that the entire annular member may be formed from a single piece of metal.

To additionally cool the air, the stem 3 is provided with an angularly disposed lair passa-ge 14, which passage has its intake end 15 spaced from the ends of the stem and its discharge end 16 in the end of the stem where the Iair will be discharged through the mouth isprovided in connection'with tliebowl of' a pipe whereby additional air will be provided from the atmosphere to smoke passing through a pipe, therebyhcooling the `smoke and means is provided whereby the volume o-additional air .maybe regulated as -idesired The invention having been set-forth-what is claimed as newan'd useful is l".y Thecombination with a bowl 'of a pipe having ka chamber therein and air passages extending from the upper end of the bowl and terminating in the Chamber lof the bowl, of an annular-channeled member rotatably 'mounted' on the upper end of the bowl, said Y -channeled:member having its upper flange horizontally disposed and provided with apertures normally registering with the upper ends of the air passages, said channeled member having its lower flange inturned and rotatably mounted in an annular groove in the outer pe-riphery of the bowl.

2. The Combination with the upper end of a Ybowl of a pipe, said bowl being provided with air passages extending angularly downwardly from-the' upper end .thereof and terminating in communication with the chamber of the bowl at a point spaced from the lower end thereof, of Vmeans forregul-ating the volume ofair ypassing through saidairpassages, said 'means comprising an annular vmember rotatablymounted on the upper end of the bowl, and provided with apertures normally registering with the air passages.
