Feb. 29, 1944. G. A. DECKER SMOKING PIPE Filed llay 15. 1943 Patented Feb. 29, 1944 UNITED STATES PATENT OFFICE SMOKING PIPE George A. Decker, Sioux Falls, S. Dak. Application May 15, 1943, Serial No. 487,l62

3 Claims. (01. 131-198) This invention relates to certain new and useful improvements in smokers pipes.

The primary object of the invention is to provide a smokers pipe wherein the smoke passage from the bowl of the pipe to the tip of the mouthpiece is extended in a sinuous line to increase the length of smoke travel before entering the mouth of the smoker, and being operative for cooling the smoke duringsaid sinuous passage.

A further object of the invention is to provide a smokers pipe of the foregoing character wherein the bowl of the pipe is formed with an enlargement that is vertically chambered and constructed to provide sinuous smoke passages for increasing the length of smoke travel from the bowl of the pipe to the tip of the mouthpiece so as to cool the smoke during use of the pipe.

A still further object of the invention is to provide a smokers pipe wherein the bowl ofthe pipe is provided With a lateral enlargement having a chambered portion for the reception of a metallic cylinder into which a removable metallic plug with tortuous passages therein is mounted, the upper end of the plug being constructed for the admission of air thereinto for mixture with the smoke flowing from the pipe bowl to the mouthpiece for the purpose of cooling the smoke and reducing condensation to a minimum, the heat of the smoke being further dissipated by conduction to the atmosphere during its flow in contact with the metallic cylinder and plug.

It is a further object of the invention to provide a smokers pipe wherein the bowl portion is provided with a lateral enlargement that is vertically bored to communicate with the smoke passage through the stem of the pipe with a chamber at the upper end of the enlargement communicating with said bored portions and closed at its upper end by a vented metallic cap to cause the smoke flowing from the bowl to travel in a sinuous path to the mouthpiece of the pipe for cooling of th smoke and condensation of moisture therein.

With the above and other objects that will appear as the nature of the invention is better understood, the same consists of the novel combination and arrangement of parts as Will be more fully pointed out in the following description.

In the drawing:

Figure 1 is a top plan view of a smokers pipe constructed in accordance with the present invention;

Figure 2 is a vertical longitudinal sectional view taken on line 2--2 of Figure 1, showing the lateral enlargement carried by the bowl of the pipe with the sinuous smoke passage therethrough;

Figure 3 is a side elevational view of the metallic plug removed from the lateral enlargement of the pipe bowl, and

Figure 4 isa vertical longitudinal sectional view of a pipe bowl and stem in which the tortuous passages for the smoke are directly formed in the lateral enlargement of the pipe bowl.

7 Referring more in detail to the accompanying drawing and particularly to Figures 1 to 3, there is illustrated a smokers pipe formed of any suitable material such as briar or the like that comprises a tobacco bowl 5 carrying a laterally "directed stem 6 to which the usual mouthpiece! is removably attached. The base of the bowl 5 has a smoke part 8 therein communicatin therewith and a smoke passage 9 extending through the stem 6 to the mouthpiece 1. 'Asshown more clearly in Figure 2, the pipe bowl 5 and stem 6 has an enlargement l0 formed integral therewith, which rises from the stem 6 and is disposed laterally of the bowl 5 and at the side thereof nearest the mouthpiece l. The enlargement I0 is provided with a vertical opening H which extends through the upper end of the enlargement and terminates at its lower end as at l2 below the smoke passage 9 in the stem 6, and formsaseat.

A metallic cylinder l3 having a closed'bottom l4 and open upper end is frictionally received within the vertical opening H with the bottom wall l4 thereof resting on the seat l2, while the upper end of the cylinder l'3 is flush with the upper end of the enlargement H]. A cylindrical metal1ic plug I5 is fractionally received in the cylinder l3, and is removable from the cylinder for cleaning purposes. The plug is supported at its lower end on the bottom wall M of said cylinder, and is centrally cut away at its upper end to provide a chamber l 6, while the lower portion of said plug is bored to provide a pair of vertically extending longitudinally spaced smoke passages l I and I8 communicating at their upper ends with the chamber Hi. The passages l1 and I8 are provided at their lower ends with laterally directed ports l9 and 20 which register with openings 2| and 2|" in the side wall of the cylinder l3 and are alined with the smoke passage 9 in the stem 6 of the pipe.

A metallic plug or cap 2| provided with a central vent 22 is removably threaded into the upper end of the cylinder l3 as shown in Figure 2.

From the above detailed description of the invention it is believed that the construction and use thereof will at once be apparent, it being noted that smoke from the bowl 5 entering the port 8 travels through the extended sinuous passages l'! and I8 in the plug 15 before entering the outlet end of the smoke passage 9 in the stem 6 to the mouthpiece 1. A limited quantity of air enters the chamber l6 at and through the cap vent 22, for admixture with the smoke to aid in cooling the smoke and be effective for reducing condensation to a minimum. Also, the cylinder l3, plug 15 and plug closure 2| being formed of metal, a large amount of heat in the smoke is reduced by conduction to atmosphere and thereby produces a cool and pleasant use of the pipe. The plug I5 while frictionally retained within the cylinder may be readily removed for purposes of cleaning and the like.

In the form of the invention illustrated in Fig ure 4, the pipe bowl 5a carries a lateral stem 6a with a smoke passage 9a therein while an enlargement Illa rises from the stem 6a and is carried laterally of the bowl 5a. The upper end of the enlargement Illa is vertically chambered as at 16a and below said chamber there is a pair of longitudinally spaced vertical passages Ila and l8a that extends below the smoke passage 9a. in the stem. A removable metallic cap 2 la is provided and has a center vent 22a, the cap closing the upper end of the chamber 16a. The smoke from the bowl 5a enters the passage 9a through the port So at the lower end of the bowl, travels upwardly through the passage l'ia, enters the chamber Mia and then passes downwardly through the passage 18a to the smoke passage 9a.

While there are herein shown and described the preferred embodiments of the invention, it is to be understood that minor changes may be made therein as will fall within the scope of the invention as claimed.

I claim:

1. In a tobacco pipe of the character described, a bowl having a stem projecting therefrom and having a smoke conducting passage leading from the bowl through said stem, an enlargement on the bowl disposed laterally thereof and rising from the stem, said enlargement being provided with a vertical chamber communicating with the smoke conducting passage and having an opening at its upper end and with the bottom wall thereof disposed below said smoke conducting passage, a metallic cylinder seated in said chamber and resting on the bottom wall of the latter and communicating with the smoke conducting passage, and a plug removably mounted in said cylinder having tortuous passages therein communicating with said smoke conducting passage to cause the smoke from the pipe bowl to travel in a sinuous path in its passage from said bowl to the outlet end of the stem.
