Figure 5 is a fragmentary elevation of another modified form ,of draw tube for a pipe embodying the IlVBnlJOIland Figure 6 is a top plan view of a filter disk for use in the pipes disclosed herein.

This application is a continuation-.impart of Application Serial No. 594,701, filed May i9, 1945, for Smokers Articles, which application is now abandoned.

The pipe disclosed herein comprises a metal, dished bowl holder .2S provided with a bowl supporting portion 22 which in the embodiment shown is dished, being provided with an upper threaded portion 211 anda lower condensing plug or dome 2E, which preferably is disposed on the center lineof the bowl 428 at the lowest point thereof. cylindrical or'frusto-Corlical, is re-entrant and is preferably cast integral with the bowl holder. The plug 26 being reeentrant, is open at the bottorn thereofk tothe atmosphere and projects upwardly Within the bowlv holder 2B. Therefore, when the bowl 28 'i's" in place, as shown in Figure Said plug, as shown, is substantially l, there is a relatively large cooling surface adjacent the bottom of the bowl, as the plug extends upwardly within the holder and the top 29 of the plug forms a portion of the bottom of the bowl. Thus the major portion of the condensing takes place in the main trap portion 30 between the bottom wall 3i of the bowl 26 and the bowl holder 2U. Wall 3| of the bowl 28 is preferably dished or shaped in a manner to substantially conform to the shape of the bowl holder, so that when the bowl is in position as shown in Figure 3, the trap portion 30 is of substantial magnitude. The bowl 28 is provided with corresponding threads 32 for securing the bowl to the threads of the threaded portion 24, it 'being understood, of course, that a press or other llt may be used. i Y

In the construction shown the threads of the metal bowl holder are metal, while the material of the mating threads of the bowl are of different material such as wood, corn-cob and the like, depending upon the material from which the bowl and its threads are formed, and because of the diierence in material between the mating threads of the holder and bowl there is no tendency for galling of the threads. Further, in the construction shown even though there is. a relatively short length of thread, a quadruple thread is provided which makes it possible to entirelyset the bowl by a quarter turn of the bowl, and in addition gives four entrances to the thread of the bowl, and as a multiple thread provides a construction of lesser mechanical advantage than a single thread for the same thread length, the present construction eliminates a possibility of too tightly setting the bowl on the body. It is understood that while four threads are used, the optimum number of threads is determined by the thread running length, which in the construction shown amounts to four threads.

The tobacco receiving portion or recess 34 of the bowl terminates in an opening or aperture 36 which is of similar shape (shown substantially cylindrical) to the condenser plug 26, and when the .bowl is fastened to the holder, in its operative position, the plug preferably extends within the aperture 36 and is flush with the bottom of the bowl. The plug is of slightly less diameter than the diameter of the opening 36 and thus a small peripheral opening 38 is provided which prevents the entry of tobacco into the holder, though the opening 38 actually is of substantially the same area as that of the ordinary draw hole in a conventional pipe.

In its operative position the bottom wall 3l of the bowl is preferably arcuate or of substantially the same shape as the bowl holder, the wall 3l, when the bowl is in position as shown in Figure l being slightly spaced from the dished supporting portion 22, forming the main trap 30 for moisture, condensate and the like, it being understood of course that a lter such as the disk lter 4D (Figure 6) of absorbent material may be inserted around the plug, the lter being apertured at 42 to embrace the plug 26. The lter 48 is shown in position in Figure 3.

The bowl is preferably made of a suitable briar, but other material, of course, may be used such as clay, meerschaum, corn-cob, etc., and the bowl holder is preferably of a light material such as aluminum. The bowl holder is also provided with a stem 44 comprising, for its major intermediate portions, spaced stem or side members or portions 46 which merge adjacent the 4 bowl supporting portion as at 48 and at the opposite end as at 50.

A draw tube 52 shown in Figures 2 and 3 as being corrugated in a spiral shape, which in effeet provides a continuous Weir 53, is adapted to be inserted into the passage 54 of the bowl supporting portion`which communicates with the trap 36. The end of the tube 52 extending into the passage 54 is drawn down or tapered as at 56 Vand the size of the passage 54 and tube is such as to provide a tight t. The tapered end 56 prevents a whistle when the pipe is being smoked and greatly lessons the danger of condensate running from the trap into the draw tube, and the corrugated effect of the spiral of the drawtube not only provides progressive traps but performs a cooling function.

The portion 50 is provided with the opening 58 for receiving the end 60 of the bit 62 which may be a press, screw or other fit, the passage 54 through the bit being preferably enlarged as at 66 to receive the end 68 of the draw tube 52 which is preferably split a short way from the end as at 1D and is sprung or tightly tted into the passage 6B. The bit, of course, is of any desired material, such as hard rubber, amber, Bakelite and the like, and it is seen that in cleaning, the bit and tube may be removed and replaced as a unit.

In Figure 4 a draw tube 'I2 is shown wherein separate corrugations 14 are provided forming traps separated by separate weirs 15, the bowl end 16 of said tube being drawn down or tapered as at 18, and the bit end 80 being slit as at 82 for tightly fitting that end into the passage 66 of the .bit E2.

The tube as well as the bowl holder and stem is preferably of a light weight metal such as aluminum, magnesium and the like.

In Figure 5 a plain draw tube 84 is shown having the drawn down or tapered end 86, similar to end 56, adapted to be received within the passage 54. The opposite end 88 of the tube 84 is formed similarly to the tube 52, being slit as at 58 for tightly tting said tube end into the passage 66 in the bit 62.

It is to be understood that this application is not to be limited by the exact embodiments of the device shown, which are merely by way of illustration and not limitation as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope oi' the claims.
