' This invention relates to improvements in tobacco smoking pipes.

One of the features ofthe invention comprises the novel shape of the pipe bowl which produces improved results both in the smoking qualities and in the handling facilities of the pipe. Y Y Another feature of the invention comprises the provision of, means for cooling the smoke from the pipevand at the same time making use of this eoolingmeans for the smoke to cool that portion of the pipe which is normally held in the hand.V

Other and further features of the invention will be more apparent to those skilled in the art after a consideration of the accompanying drawing and following specification wherein is disclosed a single exemplary embodiment of the invention with the lunderstanding, however, that -various changes may be made therein such-as fall withinthe scope of the appended claims without departing from the spirit of the invention. A Y

In said drawinge Y Fig. 1 is a side elevation partially in longitudinal, central, vertical section; and

Fig. 2 is a horizontal Vsection on line 2-2 of Fig.1. f

The-conventional form of tobacco smoking pipe is subject to numerous defects, the principal ones of. which may be enumerated as follows:

Clogging of the smoke passage in the stummel at its Viunctionwithl the bowl, due to flakesl of tobacco being drawn in and sometimes to moisture accumulations;

Too high a temperature of the smoke de livered to .the mouth -of the smoker resulting in a burned tongue or parched condition of the-mouth;

\ Too high a temperature of the pipe bowl where it is customarily held resulting in burning the fingers;

Inability to rest the 'pipe on itsbottom sat'- isfact'orily; and a Difficulty of cleaning, etc.

The present pipe has been developed in an effort to Vovercomethese and other failings of the conventional form of pipe and to materially increase the enjoyment from pipe smoking.

Referring to the drawings, there is disclosed a pipehaving a bowl 10 and an integral stummel 11 which maywell be formed of a conventional material, such as briarwood, meerschaum, clay, or the like. An eX- tension or stem 12 is secured to the stummel in any well-known manner, such as by the push oint 13. The bowl of the pipe is different from that of the conventional forms of pipes in that the walls 14 of the intermediate portion thereof are quite thin, as shown, and reinforced at the upper end by a flange 15 to prevent cracking. The base of the bowl is comprised of a disk 16 integral with the other portions of the bowl and preferably circular in plan, as shown in Fig. 2. This disk is of a substantial thickness, preferably about onehalf inch, as shown in Fig. 1, and it may well have a flat bottom 17 and preferably a flat top 18 outside of the bowl which will there be of annular configuration by reason of the projection of the bowl portion 141 therefrom. Preferably, the stummel extends directly from this base portion or disk and will be of the same diameter as the thickness of the disk to produce a pleasing effect, as shown in Fig. 1. The projecting portion of the disklike base may be considered as a circumferential fiange around the bottom of the bowl.

The bowl contains a tobacco receiving compartment 19 of the customary form, preferably having the tapered configuration shown in Fig.V 1 and having a substantially flat bottom 20, thus differing from the usual arrangement. The side wall of the tobacco compartment is undercut at the bottom forming a peripheral groove 21 contiguous to the tobacco compartment, in communication therewith around its fullv circumference and at the bottom thereof, which groove may well be about three-sixteenths of an inch in depth measured horizontally in Fig. 2. The vertical height of this groove should not be much more than about one-sixteenth of an inch in order that under ordinary circumstances, tobacco which is packed into the compartment 19 does not get into this groove, which will hereinafter be termed a draft passage, since it provides means for the smoke to separate itself from the tobacco in the compartment and pass around this passage and enter the bore 22 in the stummel which communicates with the draft passage. In this way, the smoke leaves the tobacco throughout a large area at the bottom of the bowl, and since the bore of the stummel enters this draft passage, it will be seen that an even draft will be provided over the whole area of the bowl, and more even burning of the tobacco will result, maintaining` a cooler condition of the whole bowl.

In the present arrangement, the annular draft passage is made to perform t-wo addi tional functions by the simple provision of the direct air passage 23 leading from the upper wall of the draft passage 21 to the upper surface 18 of the disk or flange, where it extends beyond the bowl portion 14. This passage 23 is of such size as to admit a quantity of cool air directly from the atmosphere into the circumferential draft passage where the air mixes with and cools the smoke before it passes into the bore of the stummel, and then into the stem. The second function consists in keeping the base, disk, orflange of the bowl cool at all times so that it may readily be handled by the smoker without burning his fingers no matter how hot the bowl may become. This cooling of the flange or disk results from the passage of the cool air through the air passage 28 and around both sides ofthe annular draft passage 21. Preferably. the air passage 23 is diametrically opposite the bore 22 in the stummel.

The advantages of the pipe will be obvious to pipe smokers. A few features in addition to those already mentioned may be noted here. Any incipient clogging of the bore of the stummel may be overcome'by placing the thumb on top of the bowl to close the same and blowing through the stem. Even though the top of the bowl is closed, there is egress for air through the passage 23 so that the clogging material can readily be blown out of the stummel. This procedure is recommended when the pipe is first filled to insure that the passage in the stummel and the annular draft passages, as well as from the passage 23, are clear before the tobacco is lighted. Additional draft while lighting may be obtained by placing the forelinger over the opening of the air passage 23. The annular draft passage may occasionally be cleaned when required by means of a suitable bent wire or other tool which can be provided for the purpose with each pipe. The relatively thin walls of the bowl rapidly conduct the heat away from the inner walls of the bowl and radiate it, tending to produce a cooler smoke.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a tobacco pipe, in combination, a bowl and a stummel, said bowl having a tobacco compartment enlarged in diameter at the bottom to form an annular draft passage, said stummel having a smoke passage entering said draft passage and an air passage leading directly from said draft passage to atmosphere, said air passage joining said draft passage remote from said smoke passage.

2. In a tobacco pipe, in combination. a bowl and a stummel, a circumferential flange at the bottom of said bowl adapted to be grasped to hold the pipe and an annular draft passage within said flange adapted to have atmospheric air drawn therethroughto cool said flange.

3. In la tobacco pipe, in combination, a bowl and a stummel, a circumferential flange at the bottom of said bowl adapted to be grasped to hold the pipe, aztobacco compartment in said bowl extending down to the level of said flange, a draft passage surrounding said compartment at the bottomthereof and 1n communication therewith, a smoke passage in said stummel leading to said Vdraft passage, and a passage in said flange from said draft passage to the atmosphere.

4. .In a tobacco pipe, in combination, a bowl and a stummel, a circumferential flange at the bottom of said Abowl adapted to be grasped to hold the pipe, a tobacco compartment in said bowl Vextending down to the level of said fiange, a draft passage surrounding said compartment at the bottom thereof and in communication therewith` avsmoke passage in said stummel leading to said draft passage, and a passage in `said fiange from said draft passage to the atmosphere, said passage in said flange emerging on the upper surface thereof.

5. In a tobacco pipe, in combination, a bowl and a stummel, a tobacco compartment in said bowl. a circumferential groove inthe wall of said compartment at `the bottom thereof toprovide a draft passage, the smoke passage in said stummel entering said groove, and a short, direct passage from said groove to the atmosphere opposite to said stummel to admit cool air for mixing with the smoke in the draft passage and to cool the bowl about said groove.

6. In a tobacco pipe, in combination, a bowl having a flat disk-like base of larger diameter than the intermediate part thereof, a tobacco compartment in said bowl extending into said base, a stummel extending from said base, and an air passage from the upper surface of said base to and around thebottom of said compartment.
