2 Claims.

The present invention relatesto tobacco smoking pipes and specifically to pipes designed to separate from the smoke any and all liquid substances such as tars, water and other materials distilled from the tobacco, and to likewise trap and remove saliva from contact with the smoke.

Among the objects of the invention is a tobacco smoking pipe construction in which the smoke, in passing from the bowl, is separated from its content of easily condensible material before traveling to the pipe stem proper.

Another object is a construction in which any saliva passing into the stem is bypassed into a chamber out of the path of the smoke entering the stem.

Still another object is a pipe having large chambers for collection of the substances indicated and so arranged as to be easily and effectively cleaned.

Other objects will readily occur to those skilled in the art upon reference to the following description and the accompanying drawing in which Figure l is a longitudinal central vertical section through a pipe embodying the invention.

Figure 2 is a front end View of the lower portion of the bowl with a part removed.

Figures 3 and 4 are sectional views on line 33 and 4-4 respectively of Figure 1.

Figure 5 is a section on line 55 of Figure 4.

In the drawing, the pipe is shown as consisting of a bowl Ill, stem portion I I, and the removable bit l2, which latter may be inserted-in the end of the stem and held in place by friction in the well known manner.

The bit l2 will be provided with the usual longitudinal passage l3 extending therethrough and with a reduced portion l4 adapted to fit within the end of the stem II. It is also provided with a forward extension consisting of a flattened portion 15 through which extends the passage l3 and which is provided with a vertical through passage l6 intersecting with the passage l3.

The adjacent end of the stem II will be provided with an enlarged opening 20 into which extends the horizontal flattened portion [5 of the bit, and the latter divides the chamber 20 into an upper and lower portion.

Extending forward Within the stem in the lower portion thereof, is the chamber extension 25 which serves as a space for collecting any saliva or other liquids which may find their way into the chamber 20. From the upper portion of chamber 20 a smok passage 30 leads forward and into the upper part or ceiling of a forward chamber 3|. This chamber is preferably immediately below the bowl l0 and is enlarged by having it extend lengthwise of the stem II as indicated at 32. The forward portion of chamber 3| is provided with a removable end wall 33 which serves the purpose of closing the'chamber and also permits easy cleaning of the chamber 3|.

Extending from the'bowl 10 into chamber 3| is a small smoke passage 35 so arranged as to direct smoke entering the chamber away from the open end of passage 30.

It will be noted that the two chambers 31 and 20 are very much larger in cross sectional area than the passages 35, 30 and I3. The effect of this is to temporarily slow down the stream of smoke in each of the two chambers. Such slowing down permits a reduction in temperature of the smoke and likewise gives the entraining vapors a chance to condense and deposit in the chambers.

As is well known in the burning of tobacco in a smoking pipe, there is considerable distillation of tars, water vapor, etc., which if allowed to pass into the smokers mouth, produce disagreeable results. Likewise, there is usually a collection of moisture within the stem due to the condensation of some of the water vapor mentioned, which is disagreeable to the smoker.

The construction shown and described herein, however, .permits the deposit of such materials in the chambers 3i and 20 and prevents their passing through the bit I2.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

I claim:

1. In a tobacco smoking pipe having a bowl and stem portion and a separable bit, a relatively large chamber insaid stem portion beneath said bowl and having an extension into said stem, means for conducting smok downwardly and in a forward direction from said bowl to said chamber, a smoke conduit leading from the ceiling of said chamber at a point remote from and to the rear of a vertical line from the smoke discharge of said conducting means, said conduit extending lengthwise of said stem in the upper portion thereof, a second chamber in the bit end of the stem and into which said conduit opens, said second chamber having an extension into ward end flattened and provided with a vertical 10 through passage intersecting the longitudinal passage, said stem having an enlarged opening to receive said flattened end and to be thereby divided into upper and lower chambers, a smoke passage extending lengthwise of said stem from the said upper chamber to a point adjacent the lower end of said bowl, a forward chamber below said bowl and into which said passage opens downwardly, said forward chamber and said lower chamber each having an extension in the lower part of said stem and extending lengthwise thereof, a conduit leading from the bowl to said forward chamber and opening thereinto at a point ahead of the passage opening and inclined so as to direct smoke away from the last mentioned smoke passage, and removable means constituting one wall oi said forward chamber. AUGUST PASUT.
