SMOKING PIPE Filed May 25, 1940 4 Q 75 Inven$t 1 (T W Patented Jan. 2, 1945 UNITED STATES PATENT OFFICE SMOKING PIPE Willard R. Richards, Buffalo, N. Y. Application May 25, 1940, Serial No. 337,252 1 Claim. (Cl. lab-22s) This invention relates to certain new and useful improvements in smoking pipes.

It has for one of its objects to provide a smoking pipe which is so designed andconstructed as to give a clean, cool smoke, which is easy to clean and keepsanitary, and which prevents any moisture reaching the tobacco in the bowl, thereby avoiding a wet heel forming in the bowl and eliminating moisture entering the pipe-bit.

Another object of the invention is to provide a pipe having a novel grate structure associated with the bowl, and which grate structure provides a greater draft area to facilitate easy smoking and afford a free and uniform burning of the tobacco, as well as preventthe pipe plugging between the bowl and the stem.

A further object is toprovide a smoking pipe.

which embodies a novel chambered stem or tube and bit and wherein the latter may serve as a ramrod for easy cleaning of the stem.

Other features. of the invention reside inthe construction andarrangement of parts hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawing:

Figure 1 is a side elevation of the smoking pipe embodying my invention. Figure 2 is a top plan view of the same. Figure 31s a fragmentary longitudinal section thereof taken on line 3-4, Figure 2. Figure 4 is a cross section taken on line 4-4, Figure 2. Figure 5 is a sectional elevation showing the manner of cleaning the chambered stem or tube. Figure 6 is a horizontal section of a modified form of the invention.

Similar characters of reference indicate corresponding parts throughout the several views.

Referring now to thedrawing, bowl of the pipe which may be made of briar or other appropriate material, and which is provided with a tobacco-receiving chamber II and an opening I! extending transversely through the lower end of the bowl in intersecting relation to v the tobacco chamber. Fitted in this opening is a chambered stem or tube ll! of aluminumor other light weight metal. That top portion ofthe tube which intersects or bridges the tobacco chamber l0 indicates the l .H of the bowl constitutes the bottom wall thereof and is provided with a plurality of draft'ports or apertures H which provide a grate between the bowl and the tube. The bit or mouthpiece I! of the pipe is detach-ably fitted in one end of the tube l3 and its inner end terminates inan extension l8 which 8, to permit any condensation to drip into the tube It and prevent it from entering the mouth of the smoker. At its other end the chambered stem i3 is provided with a removable plug I! which normally constitutes a closure for the tube may be tapered, as shown in Figure and which may be provided witha vent l8 for introducing air into the smoke-receiving tube and cooling the same. The-fiat face of this plug is exposed to the tube, affording its ready cleaning when desired.

The bit or mouthpiece 15 of the pipe is made tube, the plug I1 is forced or otherwise removed from the tube to effect end to end thereof.

-In themodified form of the invention shown in Flgure.6, the mouthpiece 20 is provided at its inner end with packing rings 2| which not only provide a friction fit between the the tube l3 but also serve as a clean-out plug when the mouthpiece is forced through the tube in the manner shown by dotted lines in Figure 6. The projection 22 at the inner end of the mouthpiece serves to force the plug l1 from the tube and at the same time provides suflicient space'between it and the tube for the collection of any sludge contained in the tube and permit it to remain therein until the plug is removed. In this form of the invention the mouthpiece is of smaller cross section through its length than the bore of the tube l3.

While manifestly simple in construction, this improved pipe not only makes for a pleasant smoke but it prevents any excess moisture reaching the pipe bit or the tobacco in the bowl, it effectually allows all the tobacco in the bowl to be consumed with full enjoyment and provides its thorough cleaning from for cooling of the smoke. before it reaches the mouth. In addition, the pipe can be easily and readily cleaned without auxiliary cleaning means other than a struction is such that in one operation the chambered stem and its built-in grate can both be cleaned.

I claim as my invention:

A smoking pipe, comprising a bowl having an opening extending transversely through the lower endthereof, a tubular member fitted in said bowlopening and having a grate portion registering with the bowl in bridging relation therewith and forming the bottom of the bowl-chamber, a detachable plug fitted in one end of said tubular member, and a bit fitted in the other end thereof, said bit being of a cross-section to enable it to be projected through said tubular member and serve as an actuator for cleaning the same.
