Specvication of Letters Patent. Application led April 23, 1910.` Serial No. 557,163.

. Patented Mar. 7,1911.

To all whom 'it may concern:

Be it known that We, CHARLES H. ODEN- BAUGH and CHARLES A. CRARY, both citizens 'contemplated -by our invention.

of the United States, vand residents of Middleport, Meigs county, State of. Ohio, have invented certain new and useful- Improvements in Pipes; and we do declare the following to be a clear, full, and exact description of the invention, attent-ionbeing called to the drawing which accompanies this application and forms a part thereof.

p This invention relates to improvements in smoking-pipes and the ob]ect of the invention is to construct pipes 1n a certa-1n manner.

which counteracts their tendency to become excessively hot, so that the smoke 1s cooled 4before it entersthe users mouth.l

away, a pipe provided with features used.

1n connection with-'our invention. Fig. 3, shows in a similar view a pipe improved as Figs. 45 andv 6, the. latter two cross-sections of the first, illustrate at enlarged scale a member entering in the construction of the pipe as shown in Fig. 3. y A In the drawing, A indicates the bowl of lthe pipe of usual form and construction.

B is the stem thereof and G is the mouthpiece of it. y v

In pipes as now used, the air is drawn in through the open top of the bowl-where it is subject to vthe effects of heat as soon as it enters-between the-hot side ofthe bowl. It becomes further heated while passing through the hot ashes of consumed tobacco and through the zone of combustion where the tobacco is burning. In this highly heated condition it passes through the stem ofl the pipe with little chance of being cooled. before it reaches the smokers mouth.

. We prevent the preliminary heating of the air by `admitting it at the-zone of combustion, so that the air need notv pass through the hot bowl, nor through the hot ashes of consumed tobacco. Conduits .through which the air moves after it has passed-the point of combustion are lkept-l coolby free admission of air and byprovision of means whereby the heat is dissipated by favoring its radiation. For such purpose the Wall of the bowl is' foraminated, the openings a whereby this effect is obtained being closely spaced and of asuitable shape. In Fig. 2, these openings are. shown circular and in Fig. 3, they are .in form'of narrow slots.

The tobaccois in form of a plug or car- Y tridge D of a size adapted to snugly -ll the bowl. It is surrounded by a wrapper Z of suitable combustible material without a bottom and adapted to be consumed with the tobacco. This may be cigarette paper or a tobacco-wrapper analogous to the wrapper of a cigar.

The cartridges may form an article of `commerce and be. manufactured ready for use, or the wrappers, particularly if of pa.- per, may be manufactured ready for filling with tobacco by the user whenever required. The object of using this wrapper is not so much for the purpose of confining the tobacco to form the plug or cartridge, as for the purpose of producing a closure for the air-inlet-openings rz in the bowl and below the point of combustion, since admission of air below the burning tobacco would int-er-` fere with the draft. Air may always enter at the point of combustion, since the wrapper burns away with the tobacco and following the burning zone, rendersy the perforations open. Therefore when the complete cartridge is not manufactured ready for use, the mostconvenient way of procedure is to use the wrapper as a-lining for the side of the bowlby inserting it into the same, after which the tobacco is 'filled in. In this case the liningmay be 'inform of a short tube', or in sheet-form merely, and it may be manipulated in, any suitable way, with or without an appliance to placeit to a seat. air to the tobacco which prevents its preheating, thev bowl of the pipe is also prevented'from accumulating heat by reason of its perforated wall. Furthermore any heat absorbed by this wall is againquickly dissipated by the. free access of air to it above, as well as below the point of combustion. Accumulation of heat in the stem is also Outside of this direct admission of' counteracted by means which favor dissipation by radiation. These means consist of disks E of a material which is a good heat conductor. Any metal, preferably aluminum, `may do. These disksare perforated to permit'mountinfr upon the stein', and they :1re of graduated diameters, as best shown in Fig. 3, so as to conform to the usual shape of a Vpipe-stem. They are spaced apart by suitable spacing means e which may consist of short collars, or washers and interposed` between adjoiningr disks, or form integral parts thereof as shown 1n Fig. 6. These spacing means may also be obtained by; the

provision of projections as shown in Figs. 4

These dlsks may also form integral and 5. annular ribs which project from the stem.

` Having described our invention, we claim as new:

l. A pipe having a foraminated bowl in combination with a combustible lining closely fitting the interior of said bowl.

2. A pipe consisting of a bowl and of a stern and of heat-dissipating disks mounted upon the stem with spaces between them, 25 the diameters of these disks being-graduated to produce the outline of the stem in proper shape. l

Intestimony whereof, we hereunto aiix our signatures in the presence of two wit- 30 nesses CHARLES H. ODENBAU GH. CHARLES A. CRARY.
