Application led J'uly 10, 1925. Serial No. 42,683.

. an inequality of the air content therein may `be. maintained to cause a passage of cooling fluid therethrough.

' With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in thev details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed), without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a central longitudinal sectional view of my improved pipe.

Fig. 2 is a top plan view of the bowl portion the stem thereof being broken away. Fig. 3 is a view like unto Fig. 2, but a portion thereof being shown in section on on the line 3-3 of Fig. 1, illustrating the position of certain cooling means with respect to the usual air channel in a stem.

gig. 4 is a bottom plan view of Fig. 1; an

Fig. 5 is a view like unto Fig. 1, illustrating the adaptation of .m inventionft'o a bowl presentmg a rounde bottom portion.

Referring nowl more in detail to the accompanying drawings, wherein like characters' of reference denote similar parts throughout the several views, vtlieY numeral PIPE.' structurally my unproved -plpe differs but slightly over the present accepted article, in that it is provided with a bowl portion 7 having therein the usual chamber for the reception of tobacco. This chamber 8 communicates with an air channel 9 located within the shank .portionlO of said bowl. The stem or mouth-piece 11 is adapted to lit within said shank portion and a ferrule 12 is fitted over their adjoining ends for ornamentation.

As stated in the objects of my invention primarily Ihave devised meansfor cooling the bowl portion of a pipe, which under the influence of tobacco burning therein is ofttilnes heated to a point making handling of the same extremely uncomfortable.

To this end I provide means for the circulation of air through the bowl portion 7 in the form of apertures or openings 13 and upon inspection of the drawings it will beobserved that saidvopenings .extend substantially vertically through said bowl and provide an unrestricted passage therethrough from top to bottom or vice versa.

I now direct particular attention to Fig.`

3 of the drawings wherein it is clearly illustrated and shown that said openings 13 in no wise interfere with the air channel 9 in the stem 10 since they are spaced at this Y pointsufficiently apart to avoid communication therewith.

The annular series of openings thus provided are readily adapted to any particular shape' of bowl and as illustrated in Fig. 5,

the bottom of said openings emerges around the circumference of a rounded-bottom pipe and extend between the inner and outer walls of the chamber 8 as in the form shown in Fig. 1.

The operation of my device will be readily understood as it is apparent that the heat generated by the tobacco burning in the bowl chamber 8 is communicated to said 'passages 13 heating the air adjacent the burning line of the tobacco, thereby rcausing the air to rise vand to be replaced by the entrance of cool air in the bottom of said openings. By this means a constant circula-y tion of air passes through the openings,

cooling the bowl, thus accomplishing the obfject of'pmy invention.;

Iclaim:

A tobacco-smoking pipe comprising a bowl and stem portion, said bowl being rectangular in longitudinal section and provided with a'chamber leading in from the top thereof and terminating short of the bot sageways having their ends terminating. tom, the stem portion havin an air channel flush with the top and bottom of said bowl communicating with the -c amber of said portion respectively. 1o bowl portion, and a plurality of unrestrict- In testimony whereof I aix my signa- 5 ed passageways arranged between the inner ture.
