SMOKING PIPE.

Application filed February 15, 1922. Serial No. 536,699.

To all whom it may concern.

Be it known that I, POWHATAN A. WEBB, a citizen of the United States, and residing at Atlanta Fulton County, State of Georgia, have invented certain new and useful lmprovements in Smoking Pipes, of which the following is a specification.

This invention relates to devices for use in smoking tobacco and consists of a novel and simple construction and arrangement of parts which in the case of a pipe properly and evenly distributes the air passing through the bowl full of tobacco so as to secure the most perfect burning which prevents undue local burning of the bowl itself and stummel and which thus prolongs the effective life of the pipe and which collects and prevents entry to the mouth of the user of saliva mixed with the evaporated constituents of the tobacco. The novel and useful features will be more fully understood from the following description taken in connection with the drawings:

The single figure of the drawing illustrates a pipe embodying the invention in vertical longitudinal section.

In the form shown the bowl 10 and the stummel 11 are formed of wood and the bore 12 of the bowl has a gradually decreasing diameter from the top to near the bottom and has a flat bottom 13 parallel to the upper end of the bowl; For a short distance from the bottom to the bottom the bore is materially increased in diameter, forming what may be called a laterally projecting groove 14 circumferentially. This groove may advantageously have a vertical width of from 1/16 to 1/32 of an inch andits lower surface is of course a continuation of the bottom of the bore of the bowl and the depth of the groove may be 1/8 of an-inch, its diameter being 1/4 of an inch greater than the diameter of the bore immediately above it. It will be noted that the stummel 11 extends somewhat downward from the vbowl and it has a bore 15 communicating at one end with the groove 14 at its outer margin on one side and it tapers from that point in conical form to a point near the outer end. It will be noted that this bore 15 has a downward incline from the bottom of vthe bowl. A cylindrical socket 16 is formed concentrically in the outer end of the stummel 11 and it has a material greater diameter than that of the adjacent end of the bore 15 and its lower portion is materially than the socket leaving a single piece of and the bore below the lower portion of the adjacent end of the bore 15, while its upper portion merges into the upper surface of thebore 15. The stem or mouth-piece 17 has a cylindrical end portion 18 which fits: in the socket 16 of the stummel but is ofless length what may be called a chamber 19 between its inner end at the bottom and the adjacent end of the bore 15. The outer surfaces of the stem 17 are in line with the outer surfaces of the stummel, a shoulder 20 on the stem abutting the end surfaces of the stummel. that the stem 17 extends at a slight angle upwardly from the end of the stummel and has in it a bore 21which also has an upward in- It W111 be noted cline but which has its open end in the cylindrical portion18 at with the upper portion of the adjacent end of the bore 15 in the stummel. A thin cylindrical extension 22 may be formed on the the upper part in line end of the cylindrical portion l8, constitut- 1 ing the inletend for the bore 21 of the stem and it may be at a slight upward angle so as to open into the upper part of the bore 15 of the stummel. The diameter of bore 21 is slightly increased at the inlet end.

as the bottom wall 13 of the bore of the bowl 15 leads at a downward angle from the bore of the bowl to the chamber 19 and the bore 21 in the stem leads upwardly from the upper portion of that chamber and this structure provides means for collecting saliva and condensed tobacco constituents in The outlet end or mouth-piece 23 it will be seen is approximately in the same plane the chamber 19, preventing them from passing to the mouth of the smoker. The groove 14 with the suction connection through bore 15 to its outer margin serves to distribute the movement of air and smoke due to the suction substantially uniformly around the bottom of the bowl since that groove will not be filled with tobacco and the passage of air around through it will be more or less free. This causes: the burning of the tobacco in the bowl to be more uniform over the surface and prevents localizing the heat at a single outlet as is usual in pipes when the combustion reaches near the bottom of the bore of the bowl. The flat bottom of the bowl and the substantial thickness of material below that bottom effectively prevents burning through of the material of the pipe at the bottom. i

The invention is, of course, not limited to the exact details of construction shown be-. yond what is called for in the claims. I have "found, however, that a pipe gives very satisfactory results where the flat bottom 13 of the bore of the bowl is approximately a of an inch from the lower outside surface of the bowl and itsristummel, where the bore 15 of the stummel has a diameter where .it joins the cylindrical portion 16 three times as great as where it joins the groove M where the cylindrical socket 16 is of an inch long and the cylindrical end portion 18.01 the stem is of an inch long.

Although the invention is shown as embodied in a pipewhere the novel features all cooperate in producing improved results, it should be noted that the structure and relative arrangement of the stemvor mouthpiece and stummel and their bores and collecting chambers 19 which prevents liquid matter from passing along the bore from the tobacco holding, socket or chamber to the mouth or theuser and "which holds the liquid but permits emptying ,it periodically whenrequired are adapted t'oruse in cigar and cigaretteiholders where they will perform similar functions and have similar advantages and thus the invention is not limited to use in pipes except when specifledi in theclaims. v Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

Y 1. A pipe comprising abowl and a stummel, the bore of thebowl enlarged at its bottom and the hereof the stummel extending from-the side of saidenlarged bottom at a slight downward angle, a mouth-piece connected at one: end to the outer end of the stummel and having a bore communicating with the bore of the stummel and extending therefrom at a slight upward angle, and a catch chamber at the outer end of the stummel below the end of the bore of the mouth-piece. I V U I V 2. A pipe comprising a bowl and a stun' mel, the bore of the bowl being enlarged at its bottom and the bore of the stummel extending from thesideoi? said enlargedbottom at a slight do-wnward angle, gradually increasing in cross sectionirom the bore of the bowl outward and terminating in a cylindrical socket the lines of which are parallel to a transverse plane through the bowl at the bottom of its boreand which has a materially greater diameter than the adjacent end of the bore in the stummel with its central upper surface merging into the upper surface of the stummel bore.

I
