H. TAYLOR TOBACQO PIPE Filed Sept. 13'. 1938 INVENTOR ATTORNEY Patented Oct. 1, 1940 UNITED-STATES PATENT I OFFICE.

My invention relates to improvements in tobacco pipes comprising a method of and construction of elements for controlling the quantitles of nicotine and moisture content in the products of combustion by means of a temperature reducing condenser positioned in the stem of said pipes between thetobacco bowl and the mouth piece.

My invention relates to a condenser positioned in the stem of a tobacco pipe comprising a chamber communicating with the fine to. the tobacco bowl on one side and with the flue toj the mouth piece on the other side thereof, a baflie, preferably of tubular construction and of selected thermal conductivity, positioned transverse to and across the path of thedraft from one portion of the flue to the other, with means to radiate and conduct the heat from said baffle tothe outside atmosphere, and means to trap condensed moisture and nicotine in a removable receptacle at the base of said chamber.

My invention relates also to a tobacco pipe assembly comprising a tobacco bowl with a short shank to which an elongated stem of plastic or rubber material is engaged and a condenser located in said plastic stem near the bowl end thereof.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure l is a side elevation of a tobacco pipe showing a knurled cup of a condenser in the base of the stem.

Fig. 2 is a sectional elevation of a tobacco pipe showing the construction of a condenser in the stem thereof.

Fig. 3 is an enlarged sectional elevation of condenser having a tubular baflle installed in fragmental pipe stem.

Fig. 4 is an enlarged sectional elevation of condenser having a solid baffle installed in fragmental pipe stem.

Fig. 5 is an enlarged sectional elevation of a condenser chamber, without a baffle, but with a removable cup at the base of said chamber, in a fragmental portion of a pipe stem.

Fig. 6 is a side elevation of a removable tubular baffle with a reservoir cup surrounding the base thereof.

Fig. 7 is a side outline elevation of a pipe with a condenser cup installed in the shank of a tobacco bowl.

Similar numerals refer to similar parts throughoutthe several views...

In order to increase the condensation of mois-' ture and the precipitation of nicotine, tobacco tar, and other harsh elements from the products 5' of combustionlin a tobacco. pipe a condenser is provided instem I adjacentto shank I of bowl 2, and comprises bafile3 preferably of tubular construction, extending vertically through. coilof the draft, which is drawn from bowl ,2, impinging on baffle 3, traveling around it, and exhausts through flue, section" 5' and mouth piece B Bafile 3 extendsvertically from the base of a cup shaped reservoir 8 and is integral there-- 15 with and is," held A in place byfmanually turnin the knurled suriaceot cup 8;;thus screwing thef upperthreaded' end of'b'affl 3 into a threaded aperture at 9 in the upper end of chamber 4, engaging the rim ID of cup 8 against annular 20 seat H surrounding the lower end of chamber 4. The moisture content of the hot products of combustion drawn from the base of bowl 2 through flue 5 partly condenses into a liquid when said products impinge on baflle tube, because the 25 heat thereof is absorbed by, conducted through and radiated from said tube 3 to the outside atmosphere both by the circulation of air through said tube and the exposure'of the outside of cup 8 to the outside air. This lowering of the tem- 30 perature of the products of combustion causes the precipitation of the nicotine laden moisture therefrom. Not all of the moisture is precipitated while the products are passing through chamber 4 but continues to precipitate for a short distance in flue 5' and drains backinto reservoir cup 8 which forms atrap for retaining the liquid condensation against flowing into the base of the tobacco bowl 2 or into mouth piece 6; thus insuring a dry bowl and a mouth piece free from 40 liquid. Wall l6 of chamber 4 extends slightly below seat H to prevent any liquid in cup 8 from reaching flue 55" in the event the pipe should be moved around or turned over.

This invention operates on the principle of 45 the close association of nicotine, tobacco tar, certain acids and carbon with moisture at high temperatures, and by their partial elimination the smoker might enjoy a dryer and milder smoke with many of the astringent elements which deaden the senses of taste and smell removed, leaving a finer tobacco flavor to be enjoyed. Experimentally many smokers who have been unable to smoke other pipes without distress of densing chamber 4 transversely. across the path 16" metal sleeve between tobacco holder 2' and heart burn and stomach disorder can smoke pipes embodying my invention without such effects.

Varying constructions are shown in Figures 3, 4 and 5. They illustrate condenser chamber 4 with a metallic lining l2, with an annular flange forming seat II. This lining is held in place by means of a metal tube IS in flue section 5 passing through the wall of lining [2 at M. Fig. 4 shows battle 3 to be solid instead of tubular as in Figures 2 and 3 but is not as eflicient in condensing moisture as the tubular construction. In Figure 5 the preferred bafile is omitted and depends for condensation on the agitation of the draft upon the gap between sections 5 and 5' of the flue but has in common with the other constructions the removable reservoir cup 8.

The assembly of the various elements of the pipe embodying my invention not only gives a unique appearance, but provides for a place in the plastic or rubber stem for the condenser, which admits of threading for the engagement of baflle 3, though the condenser could be installed in shank I as shown in Figure 7. The installation of the condenser near the end of removable stem l makes it easy to clean, by disengaging it from shank 'l and giving it several hard flicks, making it unnecessary to unscrew cup 8-except for thorough cleaning.

In Figure 8 the tubular condenser 3" is shown in a cigar or cigarette holder being installed in a stem I.

In the operation of my invention it will be found that after smoking from one to three pipe fulls of tobacco that reservoir cup 8 will be full of brown liquid with some solids deposited on the side of bafile 3 and in cup 8. A plurality of. bafiles 3 may be furnished with each pipe, each varying form the other in thermal conductivity, as Duralumin, aluminum and copper, so that the smoker can adapt the strength and flavor of the smoke to his taste, by the selection of the desired bafile.

I do not claim that moisture does not condense in other pipes, which sometimes wets the bowl and also be drawn into the mouth, but what I do claim, and desire to secure by Letters Patent is:

1. A tobacco pipe comprising a tobacco bowl, a stem containing a flue through which the draft of the products of combustion is drawn, a metal tube extending transversely through said draft and communicating with the outside atmosphere, and a removable reservoir cup surrounding one end of said tube.

2. A tobacco pipe comprising a tobacco bowl, a stem containing a flue through which the draft of the products of combustion are drawn, a tube extending transversely through said draft and communicating with the outside atmosphere, and a removable reservoir cup surrounding one end of said tube.

3. Atobacco pipe comprising a tobacco bowl, a stern containing a flue through which the draft of the products of combustion are drawn, a tube extending transversely through said draft and communicating with the outside atmosphere, said tube having an annular flange at one end forming the bottom of a condensation reservoir, and exposed to the outside atmosphere.

4. A tobacco pipe comprising a tobacco bowl, a stem containing a flue through which the products of combustion are drawn, a bafile bar extending transversely into said flue and a removable reservoir cup surrounding one end of said baffle bar.
