SMOKING PIPE.

Application led October 30, 1923. i Serial No. $71,683.

This invention relates to smoking pipes and is particularly directed to means for securing improved smoking qualities.

Pursuant to the invention, the smoking 6 pipe includingr the usual bowl having a stem portion and a separable stemportion carrying the mouth piece. is combined with a member for eifectually removing nicotine r other moisture orsaliva and dust whereby lothere is afforded a continuously `maintained clear passage through the bore of the pipe stem for the smoke developed upon ignition of the tobacco in the bow Pursuant to the more preferred forms 1 5 of my invention, such removal of the tobacco dust, saliva, nicotine or other moisture and other products of condensation resulting in the use of the pipe in smoking, is eifected by means of a member of non-ignitible material such as metal and shaped spirally or of other nonuniplanar configuration whereby such nicotine or other moisture, dust and the like which are developed upon ignition of the tobacco in the bowl and carried upon inhalation by the smoker into the -pipe stem, are eteetually impeded and retained at distributed locations within the bore of the stem and effectively out of the path of the smoke. 'In a similar manner,

such provision of means, in the event of saliva entering the mouth piece, directs and retains the same at a similar location, out of effective intercept with the smoke passing through the pipe bore.

Such dust and nicotine or other moisture separating means serves also as a means for thoroughly cleansing the bore of the pipe, by manual withdrawal of the spiral means through the bore, as by removal of the sep- 0 arable portion of the stem from the bowl portion of the stem in a separable type of pipe, whereby upon manual withdrawal of the spiral or equivalent member outwardly V:from the pipe stern, the dust and nicotine or other moisture are transferredL exteriorly of the bore.

Further features and objects of the invention will be more fully understood from the following detail description and the accom 30 panying drawings, in which Fig. l is a vertical central sectional View through the bowl and stem of a pipe, of the form in. which the stem is separable substantially at its center;

Fig. 1G is a sectional view on line 10-10 of Fig. 9.

Referring to Figs. 1 to 6, inclusive, the pipe per se may be of any approved or desired form and general construction, and comprising the bowl 11, the stem portion 12, usually permanently secured to the bowl 11, and the separable stem portion 13, at the outer end 14 of which is the mouth piece, either permanently `or removably carried thereby. Such separable feature for the

stem portions

12, 13 may be provided by means of the reduced stem portion 15 projecting from 'the inner end of the stem portion 13 and secured by frictional fit within the recess 16 at the outer end of the bowl stem portion 12.

Within the bore 17 of the pipe stem 12--13 is disposed, pursuant to my invention, a 95 twisted or spirally coiled member 18 of aluminum or like sufficiently stiff and preferably non-corrosive material suitable for the purposes desired. Such member 18 is preferably of a length corresponding to the 100 length of the bore 17 from the mouth piece 14 to a location 19 in advanceof the center oi the bowl 11, in which circumstance the inner end 2O of the member 18 is provided with an enlarged opening 21, see Fig. 2, or 105 slot or equivalent, whereby an enlarged effective free clearance is provided for the draft from the bottom of the bowl 11 into the stem bore 17.

Upon filling the bowl with tobacco, with n.

modification,

on a greatly the stem and the dust and nicotine or other moisture member assembled, as indicated in Fig. l, upon inspiration by the smoker, the smoke is drawn through the bottom of the bowl, thence into contact with the member 18, including a considerable portion of the smoke passing through the slotted opening 21, the path' of the smoke then continuing about the passage afforded between 'the various portions of the member 18 and the wall of the bore 17 of the pipe, whereby the smoke is given a more or less centrifugal movement. The condensed nicotine. or other moisture resulting from the ignition of the tobacco, gravitates toward the bottom of the bore 17 and will be distributed intime on the bottom of the bore from the bottom of the bowl toward the mouth piece. centrifugal movement of the smoke, carrying any dust or other substance foreign to the smoke, is whirled into contact with such Acondensed nicotine or other moisture and thereby entrapped. Similarly, in the event of saliva entering the opening of the mouth piece 14, is brought toward the bottom of the bore and operates to catch dust and the like.

Such action is enhanced by providing an effective diameter of the member 18 substantially that of the bore 17 of the stem.

Such member 18 is also referably provided with suitable means or lodging the same withinl the bore 17 of the pipe stem, as by providing the member 18 with the spaced lugs 22, 23' for retaining the member 18 relativeto the reduced stem portion 15. As is indicated in Figs. 3, 4, 5 and 6, the reduced portion 15 may be provided with the correspondingly spaced

re-entrant recesses

24, 25, arranged to respectively receive the

retaining lugs

22, 23 and forming therewith a bayonet joint, whereby upon withdrawal of the separable stem portion 18, the member 18 is simultaneously withdrawn through the stem portion 12, but retained by the above described vsupport for the member 18 within the removable stem portion 13.

Such withdrawal of the member 18 through the bore of the stem portion 12 eects a displacement of the edge portion of the member 18 longitudinally along and against the wall of the bore and thus producing a scraping action, and removing dust, nicotine or other moisture and the like therefrom. Such withdrawal action may be repeated as often as desired.

Upon disconnecting the member 18 from the separable stem portion 18, and withdrawing the same through the bore thereof, a similar removal action is effected for the dust, nicotine or other moisture from the bore of the stem portion 13.

In Fig. 3, the member 18 is shown lodged with its

retaining lugs

22, 23 respectively in Such the

bayonet slots

24, 25 and the effectual diameter of the spiral member 18 substantially that of the bore 17, that is to say, to make an easy fit therein.

In Fig. 7, the opening 30 at the inner end of the 'member 18 is shown somewhat enlarged along the length of the member 18.

If desired, and as indicated in Fig. 8, the member 31, corresponding to the aforesaid member 18 may be provided with the

openings

32, 32 adjacent the opposite ends of the member 81, whereby the opening 32 located adjacent vthe opening of the mouth piece 14 when positioned within the ipe, may be employed to receive the end o the match, tooth pick, button` hook, bent Wire or the like, to afford withdrawal of the member 31 from the 'bore' of" the pipe. ASuch form of the invention may be employed in pipesy of the separable stem type, as indicated in Fig. 1, or with ipes having a stem integr-al throughout its length.

From the above,'it will be erceived, as I have discovered from actua use of my invention, substantially all the nicotine, moisture and other water content of the gases resulting from combination of the tobacco, are automatically entrapped and retained within the bore' of the ipe while sufficient full assage is provi ed at all times for the ree draft through the pipe bore. The smoking derived by means of a pipe having m invention, is cool and without any bite, and allows such pleasurable smoking for a comparatively long period of use, and particularly for relatively long periods of continuous use.

The invention also provides for read removal of thegiicotine, dust and the like rom the bore without the necessity of having any auxiliary device, such as a. pipe cleaner, and the cleansing is readily effected without soiling the hands of the user, as the cleaner member may be grasped by a piece of newspaper or cloth or the like and cleansed.

The configuration of the member 18 may be varied, as by twisting a metal strip irregularly, as distinguished from the regular spiral as is illustrated in Figs. 1 and 8, while retaining the essential features of the provision of a whirling path for the smoke through the bore, a plurality of edge 0r other portions of the body of the member in spaced contact with the walls of the bore and suitability for grasping one end thereof for facilitating its withdrawal from the bore.. In Figs. 9 and 10, I have illustrated a helically coiled member 38, and referably of a triangular or other polygonalpcross-section, to provide spaced edge or relatively sharp portions for engagement with the walls of the bore of the pipe stem.
