FEATHERWEIGHT' PIPE Application filed May 22, 1931. Serial No. 539,325.

The present invention relates broadly to improvements in a pipe construction and more particularly to means for conducting and radiating excessive heat originating within the bowl of ametal pipe of light weight.

Hitherto metal pipe bowls were partially provided with an increased radiating surface in the form of spatially arranged annular 1O fins. The purpose of the fins was to drive off the heat from the outer surfaces of the bowl transmitted from the inside by conduction. In actual practice, however, it has been found that such a construction although radiating some heat failed to provide a coo smoke with the result that hot fumes would be conducted through the pipe stem to the user.

To overcome this disadvantage the stem :9 of the pipe was provided with a plurality of fins to increase the surface radiating characteristics thereof and even with this supplemental radiating surface of the pipe, if'

used, did not produce a cool smoke.

Accordingly, one of the objects of the present invention resides in the provision I of means for producing a cool'smoke with a metal pipe without anydeleterious effects to the user.

Specifically,

39 another object is to provide a metal pipe of light weight having the bowl,

the stem and the portion of the stem providing a seat for the bowl each constituted with supplementary radiating means. Still another aspect of the invention and an advantage thereof contemplates means to radiate and disperse heat from the hottest part of the bowl.

A further aspect is to provide a pipe bowl with closely spaced fins or ribs'extending exclusively the entire height thereof and a stem for supporting the bowl with closely spaced fins or ribs extending substantially the en-' tire length thereof. r I

How all the above features of my invention are carried into effect Will be best understood from the following specific description in detail of a preferred embodiment and although such preferred embodiment is explained merely as illustrative of the inven tion and is not considered a limitation there- .on, the invention will be best understood from a consideration ofsuch specific procedure. To aid the following specific description of the construction and principles of my invention, I refer to the accompanying drawing in which.

Fig. 1 is a side view in elevation of my improved pipe construction.

Fig. 2 is a front view thereof. "Fig. 3 is a sectional view taken along the line 3-3, Fig. 2 in the direction of the arrows.

Fig. 4 is a longitudinal sectional view along 1 the line 44, Fig. 3 in the direction of the trated, the bowl may include any other suit- Y able corrugated surfaces to increase its radiating capacity as is well understood.

Depending from the bottom wall 13 of the bowl and preferably cast integral therewith is the tube or neck portion 14 provided with the axially disposed bore or channel 15 which communicates with the depression or pocket Providing a seat for the tube 14 concomitantly supporting the bowl is the elongated stem generally denoted 16, preferably cast as a. single member, of light metal, aluminum or the like and is provided, as illustrated, with the closely and spatially arranged ribs or fins 16 extending substantially the entire length of the stem to increase the heat radiatin g capacity thereof.

The seat portion 17 of the stem is enlarged and embodies fins as 18 and 19 of a'diameter greater than the fins 16' but extend substantially in parallel relation therewith. Furv v i 5 fins.18 and 20 and radially extending from the enlarged seat portion although integral therewith is the pair of spaced fins 2S and 24. Associated with the bowl seat portion 17 is an opening25, the sides thereof being suitabl connected man or gas tight fashion wit the exterior surfaces of the tube 14, in a manner Well understood in the art, but, however, in such relation that the opening of the seat is in communication with bore l5 andthe channel 21 of the stem.

Spaced from the last fin 26 which is si1ni vlar in allrespects as the fins 16' is the annular stop flange 27 from which extends the tubular nipple 28 providing means to sustain the mouth piece or holder 29 which may be connected to the nipple 'in any well known manner in communicating relationship.

Preferably,the seat for .the bowl, the stem, the flange and nipple thereof are cast in one 26 piece, although, the invention is not limited f in this respect-as these parts may be separable and suitably fastened together.

. Generally the hottest part-of the bowl. is along the lower faces thereof .and within .18 close proximity to the bottom wall 13. As

pointed out, it is desired to disperse this heat to lower the temperature of the fumes originally developed by puifing'on the holder 29 andthereby produce a cool and sweet smoke. To this end, it is apparent that the heat on wall 13 or adjacent thereto, is conducted to theneck portion 14 and therefrom transmitted to the seat 17 and the enlarged fins as 18, 19, 20, 23 and 24. heat at the hottest portion of the bowl .is 1 widely distributed and dispersed at its-source I and this action is supplemented by the radiating fins 16 of the stem, which tends to progressively and further widely distribute any heat of the fumes not diffused by the finsof the bowl seat or by the fins 12 of. the bowl. Stated in another way a supplementary radiating surface is provided from the upper plane of the'bowl to the remote end of the stem sustaining the holder. Thus a progressive and continuous heat radiating surfaces is provided although said surfaces are disposed on separate parts. 7

As many changes may be made in the above construction and many apparently widely different embodiments of the invention could be devised without departing. from the scope thereof, it is intended that all matt'er'contained in the above description or shown in the accompanying drawing shall be inter preted as illustrative and not in a limiting sense. i

I claim:

86 having an outside corrugated surface, a stem -In this way, the

connected tothe bowl havin an outside corrugated surface, a seat prov] ed on said stem for said bowl and 1n alinement therewith operative to radiate and 'a stem inclu ing a seat for said bowl, said fins radiating therefrom.

3.-As an article of manufacture, a pipe having a bowl embodying spaced annular fins extending the entire height thereofyan enseat' comprising an enlarged portion having larged stem having a plurality of spaced fins and comprising a seat for the bowl, said seat v having fins the bowl.

4. As an article of manufacture, a pipe having a bowl,'a stem connected to the'ibowl, a

holder sustained by said stem, a seat for the bowl at one end ofthe stem, the bowl,

juxtaposed with oneportion of seat and stem having spaced fins, the latterbeing disposed continuouslyfrom the upper plane of the bowl and adjacent to a remote extremity of the stem. I 5. As an article of manufacture, a pipe having a. bowl, a stem connected tothe bowl and in communication therewith, a holder sustained by said stem, an enlarged portion providing a seat for said bowl at one end of the stem, the bowl, seat and stem having closely spaced fins, the latter extending continuously from the upperplane of the bowl to one extremity of the stem.

6. As an article'of manufacture, a pipe with a bowl having a finned surface, a stem connected to the bowl also having a finned surface, a seat for the bowl'at one end of the stem having a finned surface, the fins of said seat extending laterally and radially thereof. 7. As an article of manufacture, a pipe with a bowl having a closely finned surface, a stem;

also having a closely finned surface, a seat for the bowl at one end of the stem having a closelyfinned surface below and in alinement with the bowl, the

fins of said seat extending radially, laterally and transversely thereof.
