1 Claim. 1

This invention relates to tobacco pipes and the primary object of the invention is to provide a pipe the bowl of which is constructed so that the heat created by the burning of the tobacco during the process of smoking is dissipated readily to keep the pipe cool and provide a cool, dry and mild smoke.

Another object of the invention is to provide a tobacco pipe of the character indicated above the bowl of which is open at its top and bottom ends and is equipped with a cup-shaped tobacco supporting member insertable into the bowl and retained therein by friction between the upper edge portion of the cup-shaped member and the inner surface of the bore of the bowl.

A further object of the invention is to provide a tobacco pipe of the character indicated above, the cup-shaped member of which is arranged in the bowl at such a level that the bottom of said member is located above the lower edge surface of the bowl permitting the pipe to rest in upright position on a table or the like, without the cupshaped member having contact with the surface of the table.

An additional object of the invention is to provide a tobacco pipe of the character indicated, on the lower edge of the bowl and on the bit of which a plurality of downwardly projecting ribs are formed adapted to cooperate with each other in supporting the pipe in upright position on a table, desk or the like so that the bottom edge surface of the bowl is prevented from contacting the surface of the table, desk or the like to enable cool air to enter into the lower portion of the bowl and contact the cup-shaped member to provide drying, cooling and aeration. The ribs provide a three way bracing means for supporting the pipe in its upright position and thereby lessening the probability of burning the surface of the table, desk or the like.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved tobacco pipe whereby certain advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure l is a view in top plan illustrating a pipe embodying the invention;

Figure 2 is a view partly in section and partly in elevation of the device as shown in Figure 1;

Figure 3 is a view in bottom plan;

Figure 4 is an enlarged detail sectional view taken substantially on the line 3--4 of Figure 3; and.

Figure 5 is an enlarged detail sectional view taken substantially on the line 5--5 of Figure 3.

The tobacco pipe as herein embodied comprises a bowl I Il open at its top and bottom ends. A cup-shaped downwardly tapering member II is adapted t0 be inserted into the bowl l0 and the diameter of the upper edge of said member is such that the said edge engages the inside surface of the bowl I0 frictionally as at I2 so that the cup-shaped member II is retained in the bowl I0. The cup-shaped member I I has a downwardly extending nipple-like bottom portion I3 and is arranged in the bowl IIJ so that the lower end of the bottom portion I3 is located at a higher level than the lower edge surface I4 of the bowl I Il. The tube I5 extends through a hole I6 in the wall of the bowl I0 and through the holes II and I8 arranged diametrioally to each other in the wall of the bottom portion I3 of the cup-shaped member II. The tube I5 and the nipple I3 of the cup-shaped member II are secured to each other by means of soldering in the form of a plug as at I9. This serves at the same time to close the clearance between the tube I5 and the rims of the holes I'I and I8. A hole lea extending through the solder and a lateral opening I5a extending through the wall of the tube I5 connect the bore of the latter with the interior of the cup-shaped member II. One end portion of the tube I5 is closed by a plug 2U embedded in the wall of the bowl I0 as shown. To facilitate setting the tube with the wall hole I5@ thereof directed upwardly in the proper position in the bottom portion I3 of the cup member, the outer end of the tube may be provided with the slot I5b, in which to engage a screw driver or similar tool.

A pipe stem 2l is joined to the bowl IIl and has an axially extending bore 22 and a counterbore 23. The portion of the tube I5 projecting through the hole I 6 lits snugly in the bore 22 so that the pipe stem 2| is reinforced by said tube in the end portion adjacent to the bowl I0. A pipe bit 24 has a reduced portion 25 fitting slidably into the counterbore 23. It is however, to be understood that the connection between the pipe stem 2| and the bit 24 may be made in any other suitable conventional manner. The bit is provided with a bore 26 communicating with the interior of the tube I5.

A plurality of ribs 21 are formed on and extend downwardly from the bit 24, and a pair of ribs 28 are formed on and extend downwardly from the bottom edge surface I4 of the bowl l0. The ribs 21 are arranged diametrically opposite to each other and at right angles to the pipe stern 2|. The lower faces of all of these ribs are arranged substantially in the same plane.

From the foregoing description it is thought to be obviousthat a tobacco pipe constructed in accordance with the present invention will be kept cool on account of the recess formed in the `bowl underneath the cup-shaped member and that such pipe is adapted to be placed safely in upright position on a table or the like.

I claim:

In a tobacco pipe, a bowl having a bore of a uniform diameter extending through the same and open at its two ends, a stern portion extending laterally from adjacent the lower end of said bowl and having a bore therethrough, a cup shaped receptacle positioned within the lower portion of the bore of said bowl, aligned holes in the lower portion of the receptacle and in line with said stem bore, a plug within the lower portion of said receptacle, a bore extending diametrically throughV the plug and in line with said holes in the lower portion of said receptacle and with the bore of said stem portion, said plug having a longitudinal hole opening into the diametrical bore and into said receptacle, a mouth-piece at the outer end of said stem portion, a metal tube projecting from the bore in 30 4 said stem portion into said bowl and through said aligned holes of said receptacle and said diametrical bore of said plug, said tube also having a lateral opening disposed in line with the said longitudinal hole of said plug, and a plug closing the projected end of said tube, the wall of the bowl having a recess in which the last mentioned plug is engaged.
