Patented May 23, 1939 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to an appliance for smokers and particularly to a tobacco smoking pipe.

An object of my invention is to provide a tobacco smoking pipe with a novel and improved stern structure which is of light weight, constructed and arranged to increase the path of llow of smoke from the pipe bowl to the pipe mouthpiece to thereby cleanse and cool the smoke prior to its entering the mouth of the smoker.

Another object of my invention is to provide an improved stem structure for a tobacco smoking pipe which has a back and forth iiow therethrough constructed at least in part of relatively flat wide and long passages formed between the wall of the pipe stem and an elongated reed-like element disposed therein for spreading the smoke over and in direct contact with a large area of the pipe stem so as to produce rapid and effective dissipation of heat from the smoke to thereby insure complete cooling thereof before being drawn into the mouth of the smoker.

A further object of my invention is to provide a stem structure for a tobacco smoking pipe having the features of the preceding objects incorporated therein and which has wells or pits formed in the reed-like pipe stem insert to eiiect condensation of nicotine and other condensable constituents from the smoke while at the same time providing cavities for receiving the condensable constituents.

A still further and more specific object of my invention is to provide a stem construction for a tobacco smoking pipe of the type set forth in the foregoing objects which can be readily disassembled to permit thorough cleansing and clear- .ing of collected nicotine and other sediments when necessary.

Still further objects and advantages reside in details of construction of my improved smoking pipe and in novel combinations and arrangements of parts thereof as will more fully appear in the course of the following description.

In the drawing:

Fig. 2 is an enlarged sectional View of the pipe shown in Fig. 1 and is taken on the line 2 2 thereof;

Fig. 3 is a sectional view of the pipe stem structure taken on the line 3 3 of Fig. 2;

Fig. 4 is a plan view of the smoke passage forming insert element of' the pipe stem; and

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2 showing the portion oi the element which permits communication between the passages formed thereby in the pipe stern structure.

Referring to the drawing, for illustrating my invention, I have shown in Fig. 1 thereof a to- 5 bacco smoking pipe comprising a tobacco burning bowl I0 and an integral stem portion II. The integral parts I0 and II of the pipe may be formed of processed briar or any other suitable molded or machined material. A mouthpiece I2 l0 preferably formed of molded hard rubber, or the like, material and provided with a central passage is threaded or iitted upon an elongated reedlike element, generally represented by the reference character I4 (see Fig. 2), which is inserted l5 in an elongated opening or chamber I5 hollowed out of the pipe stem II. The element I4 located Within the stern structure of the pipe may be formed of any suitable material such as hard rubber but is herein disclosed as being formed of aluminum. Aluminum is preferred because it is of light weight, a good conductor of heat, is easily machined and lends itself to a sanitary appearance. This reed-like element I4 includes spaced apart inner and outer plug ends I6 and 25 I1 the round wall surface of which ts tightly against the wall of chamber or opening I5 in the pipe stem I I to provide means for blocking the ow of smoke therearound. A threaded portion I8 projecting outwardly from the outer plug end il of elongated element I4 receives an enlarged portion I 9 of the centrally bored mouthpiece I2. An integral tapered portion 2I of the inner plug end I6 of element I4 extends a short distance into the tobacco bowl II! of the pipe. An elon- 3- gated wall portion 22 intermediate the plug ends I6 and I1 of element I4 is machined to provide hat surfaces 23 and 24 thereon which are spaced from the chamber wall vI5 of pipe stem II. The width of wall 22 is equal to the diameter of the round plug ends I6 and I'I of element I4, and the sides of this elongated wall part 22 are rounded so as to also engage with a slip fit the chamber wall I5 to thereby divide the spaces formed between the flat surfaces 23 and 24 and the cham- 45 ber wall I5 into two separate passages.

The elongated insert element I4 is provided with a plurality of bores which with the passages located between its flat faces 23 and 24 and the chamber wall I5 in the pipe stem II form an 0 extended path of ow for smoke passing from the tobacco bowl ID to the mouthpiece I2 of the pipe. This extended tortuous path of' flow of smoke is in the form of a sinuous passage for a purpose to be hereinafter more fully described. 55

A round hole 26 bored, drilled or otherwise formed in the central part of the element I4 extends from the tapered portion 2I of plug end It through the elongated flat or reed part 22 thereof to a point adjacent the inner shoulder of plug end I1. A pair of spaced apart small holes 21 are drilled through the tapered portion 2l of plug end I6 of element I4 and communicate with the bore or hole 26 therein. The forward end of bore or hole 26 and the holes 21 communicate with the interior of tobacco bowl I of the pipe. An opening or hole 23 extends from bore 26 through the wall portion 22 of element I4 and communicates with the space or passage located between the top flat face 23 of element I4 and the chamber wall I5 in stem II. A notch 29 provided in each of the side walls of the flat wall part 22 of element I4 adjacent plug end I6 thereof (see Fig. places the passage located between the bottom flat face 23 of wall part 22 of element I4 and the wall of chamber I5 in stem II in communication with the upper passage. An angularly disposed bore or hole 3l extends from the inner shoulder of round plug end I1 on element I4 to a centrally located hole 32 provided in the threaded projection i8 thereof. Thus, the hole 3l communicates with the space located between the lower at face 23 of wall part 22 on element I4 and the wall of chamber I5 in the pipe stem II and with hole 32 which communicates with the central bore provided in the mouthpiece I2. The smoke from burning tobacco in pipe bowl I0 travels through the open end of bore or hole 26 and simultaneously through the pair of holes 21, thence toward the pipe mouthpiece I2 through bore or hole 25 to the opening 28 in the wall portion 22 of element I4. The smoke enters the upper space or passage located between the wall 22 of element I4 and the chamber wall I5 in the pipe stem, and its direction of ow is reversed to cause same to travel toward the pipe bowl I0. Upon reaching the plug end I5 of element I4, the smoke passes downwardly through the notches 29 and into the lower space or passage located between the wall part 22 of element I4 and the chamber wall I5 in pipe stem II. Thus, the smoke again has its direction of iiow reversed and now travels to the hole 3l through which it flows into hole 32 and through the passage provided in the mouth piece I2 of the pipe. By this unique arrangement the path of flow of smoke is materially increased by element I4 to provide a sinuous or tortuous smoke passage which is of at least two-thirds greater length than can be obtained from the conventional straight smoke passage in a pipe stem of equal length tothe stem of the pipe disclosed.

By referring to Fig. 3 of the drawing, it will be noted that the separate passages formed between each flat face 23 and 24 of elongated wall part 22 of element I4 rand the wall of chamber I5 in the pipe stem II is relatively flat and wide. These flat, wide and long smoke passages are an important feature in the present pipe stem structure because the passages serve to spread the smoke over and into direct heat exchange contact with an increased area of the pipe stem II to thereby morey rapidly and effectively cause the heat of the smoke to be dissipated through the stem II to the atmosphere surrounding same. Since side walls of the elongated reed-like wall part 22 of element I4 contact the chamber wall I5 in. pipe stem II and since the element I4 is formed of aluminum or any other good heat conducting material, heat absorbed thereby frorn the smoke is rapidly transferred to stern II and dissipated from the pipe. This improved method of dissipating heat from the smoke results in a smooth, dry and cool smoke which eliminates tongue bite and raw mouth of the smoker.

My improved structure is constructed to, in addition to cooling the smoke, effectively condense nicotine and other condensable constituents of the smoke therefrom during its passage through the tortuous or artificially prolonged labyrinthine passage. For this purpose I provide in the flat faces 23 and 24 of the elongated reedlike wall part 22 of element I4 a series or a plurality of rows of substantially semicircular cavities 35. The depressions or cavities 35 form pits or wells within the long relatively flat wide smoke passages and thereby materially increase the area or wall surface of these passages to prolong flow ofsmoke therethrough. These wells or pits 35 cause nicotine and other condensable constituents in the smoke to be condensed therefrom during its prolonged flow' lengthwise in one direction along the face 23 and in the opposite direction along the face 24 of element I4. The nicotine and other condensable substance condensed out of the smoke may accumulate or be collected in the wells or pits 35 without danger of blocking the flow of smoke in the flat wide smoke passages since these wells or pits increase the area of the passages.

The pipe mouthpiece I2 and the elongated reed-like condenser or filter element I4 are threaded to one another and the element I4 is slip tted within the opening I5 ofI the pipe stem II. Therefore, the element I4 is readily removable irom pipe stem I I for cleaning and clearing same of nicotine deposits by rotating and pulling outwardly on the pipe mouthpiece I2. The easy removal of element I4 permits the pipe stem structure to be readilyv disassembled and cleaned when necessary. The condenser or filter element I4 and the flat wide smoke passages formed thereby prevent slugs, flakes and juices from entering the smokers mouth. The element I4 adds no appreciable weight to the pipe structure, is easily machined or readily cast and provides with the stem of the pipe a novel and improved pipe stem construction.

It will be apparent from the foregoing that I have provided an improved smoking pipe having a novel stem construction which produces a filtcred, cool Smokefree of nicotine, juices, slugs or flakes. These features, while combining to protect the smoker from a biting tongue, raw mouth and the ill effects of nicotine and other products resulting from theburning of tobacco and inhalation of its smoke, also contribute to produce a pleasing smoke and to improve the taste of any tobacco. The pipe stem construction described is of a simplified structure, can be manufactured at low cost, and the elongated reed-like insert element thereof while not increasing the weight of the pipe is of a permanent nature. By increasing the area of certain parts of the tortuous or sinuous smoke passage, I have created an artificially prolonged labyrinthine travel of the smoke from the tobacco. bowl to the mouthpiece of the pipe, and this feature together with the structure of the filter/or insert element of the pipe stem construction condenses substantially all of the condensable constituents from the smoke before the smoke can enter the smokers mouth.
