4 Claims.

This invention relates to smokers pipes.

It is one of the objects of the present invention to provide an improved pipe which will function to minimize the nicotine and tobacco smell from smoke before smoke is inhaled.

In accordance with the principles of the present invention the pipe bowl is made in two parts. The upper part contains the fire bowl for tobacco and the lower part contains smoke filtering material placed over a smoke well where the stem enters the pipe. The fire bowl consists of a tobacco holder of metal or the like, perforated at the center to permit the drawing of air through the tobacco. .A convex pan is placed under the bottom of the fire bowl and so arranged that when the two pipe parts are assembled the convex pan comes down on top of a mass of filter material. The bottom of the tobacco bowl is also made convex, the center containing the smoke drawing opening and the edges containing holes through which the tobacco drip that runs off of tobacco under heat may pass into the bottom pan where the drip is retained.

The pipe will last indefinitely since there is nothing readily to wear out nor to burn out, except, perhaps, the filter material, which may readily be replaced. Should the whole pipe seem to have accumulated a tobacco or smoke taste it may be taken apart and washed without injury to the parts, thus producing the effect of a new, fresh pipe.

The pipe body may be made of any desired material such as, for instance, wood, plastic or other pipe materials. Also, the inner part of the pipe, such as the fire bowl and the convex pan above the filter, may be made of any desired materials.

The attainment of the above and further ob jects of the present invention will be apparent from the following specification taken in conjunction with the accompanying drawing forming a part thereof.

In the drawing:

Figure 1 is a longitudinal sectional view of a pipe embodying the present invention;

Figure 2 is a section taken alon the line of Figure 1;

Figure 3 is a section of Figure 1;

Figure 4 is a fragmentary prospective view of the tobacco receptacle or burner of the pipe of Figure 1; and

Figure 5 is a perspective view of the drip pan of the pipe of Figure 1.

Referring now more particularly to the drawtaken along the line 33 ing, the pipe 1 consists of the usual stem I2, which may be in one or more parts, and a twopiece bowl 3. The two-piece bowl consists of an upper section 4 and a lower section 5 which, in this instance, is integral with a part of the stem 12. This much of the pipe may be of any other or standard construction.

The upper section 4 of the pipe bowl has a container or fire bowl I removably fitted snugly thereinto. The container may be of a thin section of metal or of any other desired material. The container has holes 89 formed at the bottom periphery thereof and has an upwardly convex bottom ID with a central hole ll therein. The bottom of the container 1 is spaced from the inside of the bowl section 4 by a space I3. The bottom bowl section 5 has a drip pan l5 removably inserted therein but fitting snugly in place. The drip pan has an upwardly convex bottom H3 at the top of which there are one or moreholes ll--ll. Below the drip pan I5 is a space I8 filled with a replaceable smoke filter [9, below and at the center of which is a smoke and air chamber 20, which chamber 20 communicates with the usual duct 21 in the pipe stem.

In smoking the pipe the tobacco is placed in the container i and ignited in the usual manner. Any moisture that may condense, or tobacco drip that may be formed, will naturally gravitate to the bottom of the container 1 and, because of the upwardly concave shape of the bottom, it will fiow out of the container at the holes 9 therein, thus dropping into the pan [5. When suction is applied to the pipe stem a current is drawn through the holes 8 in the container 1, and the holes H in the pan l5, thence it fiows through the smoke filter Hi to chamber 20 and to the passageway 2 I.

It is to be noted that there-is an appreciable space I4 between the pan l5 and the bottom of the container 1. As a result of this space the condensate in the pan I5 is not subjected to appreciable heat and therefore does not tend to volatilize to any appreciable extent. If any such volatilization were to take place the vapors would necessarily fill the space M above the pan and then would be drawn .through the stem 21 during the smoking action and thereby impart a bitter and objectionable taste and smell to the smoke. The pipe may easily be taken apart for cleaning.

The lower section 5 of the pipe is provided with a central vent 22 which is of very small diameter. This allows the smoker to draw in a certain amount of air which is mixed with the smoke before it gets to the mouth of the smoker, thereby reducing the temperature of the smoke. Another purpose of this vent is that a y smoke that is accidently blown back into the pipe by the smoker can be expelled through the vent without having to pass through the filter I8 and the mass of tobacco in the bowl. If desired this vent may be omitted.

The pipe proper may be made of any materials now used for pipes, such as, for instance, wood, plastic, clay, or the like. Furthermore, the fire bowl I and the convex pan l5 may also be made of any desired material. It is thus apparent that the pipe of the present invention is simple and economical of construction, certain and reliable in its action and afiords the benefits above set forth.

In compliance with the requirements of the patent statutes I have here shown and described a preferred embodiment of my invention. It is, however, to be understood that the inventim is not limited to the precise construction here shown, the same being merely illustrative of the principles of the invention. What I consider new and desire to secure by Letters Patent is:

1. A tobacco pipe including a bowl, a tobacco container in the upper end of the bowl, a pan below the container for catching and retaining moisture formed in the container and means forming a suction passageway below the pan, said pan and said container having openings therethrough for applying suction therethrough, the pan and the bottom of the container being both upwardly concave as viewed from below, and the opening through the pan being in the top thereof, the lower periphery of the pan being imperforate to hold the moisture collected in the pan, the openings in the container being some at the lower outer periphery of the concave bottom and some at a level above the lower outer periphery of the concave bottom the pan being spaced from the bottom of the container to be substantially outside of the zone of combustion in the container by burning tobacco, whereby the moisture that collects in the pan is subjected. to a minimum of volatilization, and a mass of filtering material filling the pocket formed by the underside of the upwardly concave pan.

2. A smokers pipe including a bowl, a generally cup=-shaped tobacco holder in the bowl, the bottom of the holder being upwardly concave as viewed from below for guiding moisture that is formed in the pipe to. the periphery of the container, said holder having openings in the bottom periphery for permitting the outflow of such moisture, and having at least one smoke-flow opening above said first mentioned openings, a drip pan in the bowl below the tobacco holder, said pan being also upwardly concave as viewed from below and imperiorate around its outer periphery to collect and hold the moisture dripping from the tobacco holder, said pan having a suction opening therethrough in the upper part thereof, and means forming a suction passageway below the pan.

3. A smokers pipe including a bowl, a substantially cup-shaped tobacco holder in the bowl,

the bottom of the holder being upwardly concave as viewed from below for guiding moisture that is formed in the pipe to the periphery of the container, said holder having openings in the bottom periphery for permitting the outflow of such moisture, the holder fitting snugly within the bowl for the major portion of the area of the side of the holder but being of a slightly less outside diameter at the bottom thereof than the adjacent inside diameter of the bowl to leave a space between the bowl and the side of the holder at the lower portion of the holder, the lower portion of the side of the holder having perforations therethrough for the passage of smoke from the holder into said space, a drip pan in the bowl below the tobacco holder, said pan being also upwardly concave as Viewed from below and imperforate around its outer periphery to collect and hold the moisture dripping from the tobacco holder, said pan having a suction opening therethrough the upper part thereof, a mass of filtering material filling the pocket formed by the underside of the upwardly concave pan and extending across the suction opening therethrough, and means forming an air suction passageway below the pan.

4. A tobacco pipe including a bowl, a removable tobacco container in the bowl and extending up to the top of the bowl, the container having an upwardly curved bottom so that moisture forming therein will be guided to the periphery thereof, the periphery of the bottom of the container being perforated to permit moisture therethrough, the lower portion of the side of the container that extends upwardly from the periphery of the bottom being spaced from the inner surface of the bowl to leave a space between the inner surface of the bowl and the lower portion of the upwardly extending side of the container and being perforated above the bottom or" the container so that some smoke being, drawn through the pipe will pass through the container through the periphery thereof and above the first mentioned moisture passing perforations, an upwardly curved pan below the. container for catching and holding condensed moisture,

said pan having an opening thereth-rough, a smoke filter chamber below the pan, and a suc tion passageway leading to said chamber.
