Description

Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE Application January 16,

3 Claims.

This invention relates to tobacco pipes the principal object being to provide such a pipe from which it is possible to obtain a more pleasing and cool smoke than heretofore known.

Another object is to provide more convenient means for cleansing of the pipe.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a central vertical section through one of the improved pipes showing a fragment only of the stem; and

Figure 2 is a top plan View of the outermost bowl, and with the inner bowl and top of the pipe removed.

1 represents the inner bowl and 2 the hollow cylindrically shaped body portion, the former being provided with an upper annular flange like enlargement having the depending internally screw threaded rim 3 formed integral therewith, and the upper circumferential edge of the body portion 2 is stepped and screw threaded for accommodation of the screw threaded portion of the inner bowl. The latter is provided with a rounded or arcuately shaped bottom as at 4, through the edge of which is provided the smoke outlet or port 5, and which port communicates with the chamber 6 formed within the outer bowl below the innermost one. The lower end of the body portion is provided with the screw threaded coveror bottom '7 so that it may be conveniently removed, and within the chamber 6 may be placed an absorbent washer or disc as at 8, which may be of any material such as calcium chloride or the like for absorption of the moisture, which might otherwise collect therein.

The smoke passageway within the circumferential wall of the body portion comprises a plurality of preferably parallel vertically disposed channels or holes illustrated at 9, and alternate pairs of which passageways are connected by short circumferential passageways l0 at their upper ends, and by like passageways ll at their lower ends. In the preferred arrangement of such passageways, the communication with the chamber 6 occurs at the bottom of one of the vertical channels 9, next to the like channel 9 with which the stem 14 communicates; such connection being illustrated in dotted lines as at 12, Figure 2.

The communication of the passageway to the stem is illustrated at 13 so that the nal course of the smoke towards the stem in the final passageway 9 is upwardly.

It will be noted that by this construction all of the holes 9 are through holes in respect to the body portion 2 so that when the bottom 7 and the bowl 1 are in place upon the body portion 2,

193s. serial No. 652,016

(c1. 1st- 12) the smoke passageway is complete. Otherwise when these elements are removed from the body portion 2 all vertical and circumferential passageways are readily accessible for cleansing purposes.

I am aware that pipes have been constructed with more or less tortuous smoke channels about the circumferential edges thereof, but having objections as to the convenient cleansing of same and lacking provision for the collection of nicotine or the like which may be cared for intermittently in my improved construction.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

l. A tobacco pipe comprising a body portion having a plurality of vertical, spaced passageways therethrough forming a tortuous course for the smoke, a stem communicating with the upper end of one of said passageways, an inner bowl unitable with the body portion and having a flange overlapping the upper end thereof and closing communication between the upper ends of said passageways excepting each with a next adjacent one, and a bottom for said body portion removably attached to the lower end thereof and closing communication between the lower ends of said passageways excepting each with a next adjacent one.

2. A tobacco pipe having an inner bowl, a cylindrically shaped body portion, a flange integral with the inner bowl for overlapping attachment to the body portion for closing communication between the upper ends of the hereinafter mentioned channels, a chamber intermediate of the bottoms of the bowl and body portion, vertical,

circumferentially spaced channels passing entirely through the body portion one of which channels communicates with said chamber and another with the stem of the pipe, circumferentially disposed channels connecting alternate pairs of said vertical channels at their upper ends, and like channels connecting alternate pairs of said vertical channels at their lower ends.

3. A tobacco pipe comprising a cylindrically shaped hollow body portion having a plurality of circumferentially spaced smoke passageways therethrough, each of which communicates with an adjacent one, a bottom removably attached to said body portion, a tobacco bowl having a hole in the bottom thereof removably fitting the interior of the body portion and having a ange overlapping the upper end of said body portion, a stem communicating with one of said smoke passageways, and anadjacent passageway communicating with the hole in the bottom of the bowl.
