Application med na 27, 1927. Serial no. 194,646.

This invention has I struction of a pipe for its objects the confor smoking tobacco wherein the nicotine shall be practically wholly eliminated from the smoke on its way to the users mouth; and for keeping the exterior of the pipe comparatively cool.

To these ends, I have devised the construction hereinafter set forth and illustrated in the drawings forming'a part of this specification, and in which Figure 1 is a side sectional view of a pipe embodying one form of my invention. Figure 2 is a horizontal section of the same on the line 22 in Figure 1. Figure 3 is a side sectional view of another form of the invention.

The construction illustrated in Figs. 1 and 2 is in two parts, the bowl 1 and the body 2. The body has a cistern 3 into which the bowl descends, and an annular chamber 4 in its wall into which the pipe stem 5 opens. The upper part of the bowl 1 is radially enlarged, as at 6, and threaded to screw into the upper end of the inner wall 7 by which the annular chamber 4 is inwardly bounded; and the bowl is further provided with a flange or cap 9 enclosing the entire wall of the body 2. Below the shoulder 6, the bowl is spaced fro the wall 7 and also from the floor of the cistern 3; and is provided with an opening through the bottom, of the smoke and vapors from the burning tobacco down into the cistern 3.

The oil of nicotine dripping through the opening 10 collects in the cistern, but the smoke rises up between the exterior of the bowl 1 and the wall or partition 7, until itreaches and passes through a hole 11 in the wall 7 into the annular chamber 4. To reach the pipe stem 5, which opens from the opposite side of the body 2, the smoke must move half-way about the wall 7; and not only so, but it must first enter the annular tube 12 through an opening 18, and traverse the same until it can find its exit through an opposite hole 14 to permit it to reach the pipe stem.

I prefer to make the tube 12 of some inexpensive and more or less fibrous material similar to blotting paper, in order that it may ab- -1 with a multiplicity of as at 10, for the passage P sorb any remaining nicotine precipitated therein.

Thus disposed, three different places are provided for the collection of the nicotirie; first, the cistern 3; the bottom of the chamber 4, and the annular tube 12; thus making sure that practically none of the nicotine can reach the mouth of the smoker. I

For ensuring that the outer surface of the pipe shall be kept from becoming uncomfortably hot, I provide the outer wall of the body vertical passages 15 reaching entirely through from the bottom and up through the flange 9. To make sure that the passages through the flange shall communicate with those in the body, an annular groove 16 is formedeither in the flange or in the body, but preferably in the latter, cutting into the ends of the passages 15.

In the construction shown in Fig. 3, the pipe is made in three parts, the cistern 20 being separable from the body 21 and internally threaded at 22. The bowl 23 is provided with a radially projecting flange 24 threaded to mesh with the threads 22, and by means of which it is held in place with its top flange h 25 seated upon the body 21. Intermediate of the top and bottom of the bowl are two spiral flanges 26 adapted to receive the smoke at one 'oint and to deliver it to the stem 28 at a diametrically opposite point.

To enable the, products of combustion to reach the cistern 20 from within the-bowl, the floor of the latter is given a hole 27, preferably near one side and sloping farther from the center at its lower end to present the products close to the wall of the cistern. A lip 29 is also provided for the lower end of the hole to ensure against any-liquid adhering to the under surface of the bowl and creeping along the same.

Up through the flange 24 diametrically opposite the hole 27 is a passage 30, whereby the smoke from the bowl passes downward through the hole 27, across the cistern, and up through the hole 30 into the lower portion of the space about the bowl, and thence through the space between the spiral flanges 26 to the pipe stem; thus ensuring that no nicotine can reach the mouth of the smoker. 109

I After suitable intervals of use, the pipe is to body for insuring communication between be taken apart and the accumulations of nicosaid apertures and a consequent open line of tine and other products of the consumed circulation at different points around the wall tobacco emptied out from the parts. of the combined body and cistern.
