' This invention relates to tobacco pipes and is intended to provide construction and arrangement adapted to produce etlective aeration of the pipe stem without impairing its draft or drawing qualities, while making simple and convenient provision for the collection of condensed moisture and for easily and conveniently cleaning the p pe.

heretofore it has been proposed to provide tobacco pipes with air passages or inlets for the purpose of cooling the smoke and condensing the volatilized constituents of the tobacco, but such proposed constructions have not been satisfactory in use because, as,

arranged, they impair the drawing qualities or draft, making the pipe difficult to smoke. and because they fail to eliminate the strong or stale flavor of the pipe which many smokers find objectionable. The tendency to clog the passages was a further unsatisfactory consequence of such proposed constructions. 7 p

it is the object of the present invention to so construct the stem of the pipe as to largely condense the volatile constituents of the to bacco but without impairing the drawing qualities of the pipe, and at the same time make provision for easy and complete access to the cooling and condensing chamber to permit thorough and easy cleansing of the r p With such ends in View the invention consists primarily in providing the stem of the pipe with an intermediate condensing or cooling chamber without affording any obstacle or impediment to the main smokeladen current passing from the bowl to the mouth, while admitting fresh air in said chamber as an induced current entering said chamber in the opposite direction to that of the moving column 01. smoke, and coming into contact with said smoke column in a manner that tends to partially cool the smoke column which it surrounds but without appreciably diverting said column from its direct rearward course to the mouth. This provision of a condensing and cooling chamber arranged to allow direct passage of a smoke column through it, vwhile subjecting said column moving across the chamber to the cooling action of afresh air current, and that without making the pipe dithcult to smoke becauseot impeded or diminished draft, is the principal feature of this ntion. By the chamber in the bit or Serial E30,

tachable section of the stem, which is usually made of hard rubber, or non-absorbent material, and locating it so that is readily cleansed after removal of the bit, absorption of the condensing moisture is largely pre vented and the pipe may be kept sweet indefinitely instead of acquiring a stale taste.

These and other features of the invention will be particularly explained in the following specification and will be defined in the claims hereto annexed.

In the acconnoanying drawings I have illustrated a construction. and arrangement embodying the principles of this invention, in which:

Figure l is a longitudinal central section through the bowl of the pipe and the stem.

Figure 2 is a transverse section on the plane indicated by sectional line 52- 2 of Figure 1, i i

Figures 3 and 4: are similar cross sections through the stem on the planes 33 and l4r-Figure 1, as viewed from the rear or mouth piece end of the pipe in the direction of the sectional line arrows.

The bowl member 1, with its rearward extension 2 usually called the shank, centrally bored to form an air duct 2 is at usual and well known construction, and is provided at its rear end with a counterbore toreceive the tenoned or reduced forward end 4L- oi. the bit 3. The reduced forward end or tenon t, leaves an annular shoulder 5 abutting snugly against the rear end of the extension 2 of the bowl memb r so as to make a tight joint therewith.

The detachable stem member or bit has a bore 6 extending from the rear end or mouth-piece, forwardly to the duct 2 to form an air or smoke duct through which the, smoke is inhaled and expelled alternately. i i

In the forward end oil the stem is formed a cooling and condensing chamber 7, which, as here shown, is in. the form ot' a sector in cross section, the tenon being cut away from its bottom side up to the line of the duct 6, so that the air duct of the bit merges with the chamber at the forward end whereby any moisture flowing from the mouth-piece must drop into the chamber 7 which forms a trap. The rearward extension 8 of the trap is separated by the artition 8, from the draft duct or passageand is carried back well tow rd the mouthpiece to form a pocket, ha no direct
