Application May 5, 1938, Serial No. 206,258

1 Claim.

This invention relates to tobacco pipes.

The chief object of the invention is to provide a novel p-ipe in which the temperature of the smoke is fully under control of the smoker, and in which the pipe, by a novel arrangement for the admission of auxiliary air is kept dry.

The objects are accomplished by providing a main bowl for the reception of the tobacco to be burned during the smoking, and an auxiliary bowl for the reception of a second quantity of tobacco that acts as a filter and regulator for the passage of auxiliary air that is mixed kwith the smoke after the latter has left the main bowl and before it reaches the mouth of the smoker.

In the drawing: v

Figure l is an elevation ofv a pipe embodying the invention; .i

Figure 2 is a plan view; and

Figure 3 is a vertical section.

Describing the drawing more particularly,vthe

pipe comprises a stem G, having a mouthpiece v1,

and a passage 8. Carried by the forward end of the stem is a bowl designated generally 9, and preferably formed from a single block of material, such as briar. The bowl 9 has a main chamber IIl for the reception of the tobacco to`be smoked,

and which may be formed in any suitable man-A ner as to size and shape.

Adjacent the main bowl I and preferably located just to the rearward thereof, is an auxiliary bowl II that is preferably smaller incross sectional area and also less in height than the main bowl I0. .The size of the bowl I I is small in order to avoid a waste of tobacco, as will be more fully described later.

The bowl II is for the purpose of receiving an auxiliary body of tobacco I2 that acts as a lter and regulating means for the passage of air.

The bowl I I is of suflicient size to permit the introductionof a finger of the user in order to tamp the tobacco and thereby regulate'its compression and the amount of air that may pass through it.

The bowl II has at its bottom an outlet I?,r in the usual fashion of tobacco pipes. The bowl I I has an outlet I4 that merges with the outlet I3 of the main bowl ata point I5 outside of the tobacco receiving chambers of both bowls. The merged outlets I3 and I4 communicate with a passage I6, that in turn communicates with the passage 8 of the stem.

'Ihe use of the above described pipe is as follows:

Both of the bowls I and II are lled with tobacco and that in the main bowl I0 is ignited.

It will be appreciated that air will be drawn used in the bowl II.

(o1. isi-19s) through both of the outlets I3 and I4 through the stem of the pipe, and that consequently a mixture of smoke from the bowl I0 and air Yfrom the bowl I I will pass through the stem to the mouthpiece 'I.

The proportions of 'air and smoke that reach y the mouth of the smoker control the temperature, and these proportions may be accurately controlled by the smoker, by adjusting the compression of the tobacco in bowl I I, through which v 1 the air passes, whereby the amount of air that is mixed with the smoke is controlled.

The admission of air to the stream of smoke after the latter has left the outlet I3 of the main bowl I@ prevents the condensation of moisture upon the walls ofthe stem, whereby the rpipe is maintained in a clean and dry condition.

Obviously, materialsother than tobacco may be able.

It has been determined that in the process v Vof smoking when the auxiliary'bowl is packed to substantially thefsame degree of compression as the main bowl, the air and smoke will be mixed insulostantially equal proportions, and a cool and comfortable smoke will be presented to the mouth of the smoker.

Due to the small size of the bowl, the amount of tobacco used as the air controlling medium is negligible and, as a matter of fact, it may be mixed with tobacco for use in the bowl I0 after it has become dried through heat from the burning tobacco in the main bowl and vthe passage of air through it.

In order to confine the charge of iiltering material I2 within the bowl I I a cover member I1 may be applied tothe bowl. Conveniently such cover will be hinged as at I8 and will be provided with a spring holding device as at I9. Such a cover is of value in that it protects the iiltering material from being disturbed and also prevents the escape of the material to the smokers pocket when the pipe is so carried.y

While I have in the above description disclosed what I believe to be .the preferred and practical embodiment of the inventive concept, it will be understood tovthose skilled in the artA that the speciiic details are merely illustrative In order to maintain the of other equivalent constructions which may be developed in the course of use, and that the invention is to be determined not by the details as shown and described but by a fair interpretation of the appended claim.

What I claim is:

Tobacco pipe comprising in combination, a pair of bowls, and a stem having a smoke passage, said bowls being connected in multiple to said smoke passage whereby the draft from either bowl does not pass through the other bowl, said bowls being adapted to serve respectively as a combustion chamber for tobacco and as an auxiliary air chamber admitting cooling air to the smoke passage, the bowl which constitutes the auxiliary air chamber being large enough to admit the finger, and having the bottom thereof above said smoke passage whereby it is above the moisture level of the condensate formed in said pipe, a mass of tobacco in the last mentioned bowl adapted to be compressed by the finger of the user to adjustably regulate its penetrability to air, whereby the draft condition in the combustion chamber as well as the proportion of cool air admitted to the smoke, may be controlled, said bowls having a common wall serving as a medium. for heat exchange.
