2 Claims. l

This invention relates to a bowl for a. tobacco pipe, and is particularly concerned with means for Ventilating and cooling the bowl.

An object of the invention is to provide a. pipe bowl constructed to provide maximum cooling qualities for the bowl.

A further object of the invention is to provide cooling means for a pipe bowl, which cooling means provides maximum cooling adjacent the base of the bowl.

An additional object of the invention is to provide a pipe bowl having a plurality of passageways which cross each other to thereby provide cross ventilation of a pipe bowl.

Other objects will appear hereinafter throughout the specification.

In the drawings:

Figure 1 is a vertical sectional view of one form of the tobacco pipe bowl;

Figure 2 is a horizontal section taken on the line 2 2 of Figure 3;

Figure 3 is a side elevation of the bowl shown in Figures 1 and 2;

Figure 4 is a side elevation of a modication of the pipe bowl;

Figure 5 is a, horizontal sectional view taken on the line 5 5 of the structure shown in Figure 4; and

Figure 6 is a vertical sectional view of the pipe bowl shown in Figures 4 and 5.

It isa tendency of la large number of pipe smokers to smoke too fast, thus causing the pipe bowl to heat up and cause burning of the wood or other material of which the pipe bowl is constructed. Many expensive pipe bowls are thus ruined by this overheating and consequent burning of the bowl.

The present invention, in its several forms, entirely overcomes this defect of pipe bowls, because the pipe bowl is adapted to be continuously cooled by currents of air of the convection type to cause the bowl to be cooled as the tobacco in it is smoked. In accordance with Funk & Wagnalls New Comprehensive Dictionaryy 1944 edition, the word convection means transference as by heat. The passageways hereinafter described are adapted to receive air for cooling the pipe bowl.

In the drawing Figure l discloses a typical structural example of how this problem is solved by the present invention.

In this gure, A represents the pipe bowl as a whole, the tobacco chamber being indicated by the numeral I. The side wall surrounding this chamber is indicated at 2, and there is a (Cl. ISI-195) 2 bottom 3 having a circular edge 4. The bottom ofthe bowl is provided with a threaded extension 5 forming an outer rim portion of the plug l. In the lower end of the chamber I is a smoke passageway 6 connected to a circular groove 8.

In order to provide a cooling means for the pipe, the lower end of the bowl is provided with a plurality of passageways 9 having entrances or openings I0. There are other passageways I I which are parallel to each other and which are transverse to the passageways 9. These passageways I I have openings I2. Each of the above noted passageways is adapted to provide cross ventilation.

Between adjacent openings I0 and I 2 corner portions I3 are provided, as indicated in Figure 2.

Preferably the screw thread 5 has a lower abrupt terminating point I4. When the pipe bowl is screwed into the base, such ias the lower bowl section as indicated in my copending application, Serial No. 770,443, led August 25, 1947, now Patent No. 2,548,297, granted April 10, 1951, any specks of tobacco which have attached themselves to the screw threads of the lower bowl are pushed -circumferentially around these threads and caused to fall into the lower bowl.

In Figures 4, 5 and 6 the bowl F has a tobacco chamber with a smoke passage 60'. Extending on opposite sides of the bowl are other passageways 6I which are parallel to each other. Transverse to these passageways and also extending on opposite sides are passageways 62 which are transverse to passageways 6I. These pairs of passageways completely surround the tobacco chamber 6|). Additionally between each pair of passageways 60 and each pair of passageways 62 are short connecting radially directed passageways 63, as shown in Figure 5.

It will be understood that the pipe bowls shown herein may be suitably attached to a lower bowl section, and as shown in my copending application, Serial No. 770,443, led August 25, 1947, now Patent No. 2,548,297, granted April 10, 1951, are attached by screw threads, or otherwise.

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

l. In a smoking pipe having an upper bowl portion and a lower bowl portion provided with a smoke cooling and filtering chamber and adapted to be detachably secured to said upper bowl portion, comprising a base, a tobacco chamber above said base, a smoke passageway in said base extending downwardly from said tobacco chamber and adapted to communicate with said chamber of the lower portion when said portions are secured and means adapted to cool said pipe, said means including a pair of parallel substantially horizontal passageways extending through said upper portion and having openings on substantially opposite sides thereof, and a second pair of parallel substantially horizontal passageways extending through said upper portion and at right angles to said first-named pair of passageways and having openings on substantially opposite sides of said upper portion.

2. In a smoking pipe having an upper bowl portion and a lower bowl portion provided with a smoke cooling and ltering chamber and adapted to be detachably secured to said upper bowl portion, comprising a base, a tobacco chamber above ,Y

said base, a smoke passageway in said base extending downwardly from said tobacco chamber and adapted to communicate with said chamber of the lower portion when said portions are secured, and means adapted to cool said pipe, said means including a pair of parallel substantially horizontal passageways extending through said upper portion and having openings on substantially opposite sides thereof, and a second pair of parallel substantially horizontal passageways extending through said upper portion and at '4 right angles to said first-named pair of passageways and having openings on substantially opposite sides of said upper portion, all of said passageways being in the same plane and extending in directions which are transverse to the central vertical axis of said upper portion, said passageways being positioned in the base of said upper portion beneath said tobacco chamber and outwardly of said smoke passageway whereby cross ventilation means for said upper bowl is provided.
