PIPE

Filed April 8, 1926 INVENTOR BY M A TTORNE Y Patented Apr. 29, 1930 UNITED EST areas EUGENE LUCAS, 0F BABYLON, NEW YORK PIPE Application filed April 8,

This invention relates to a tobacco pipe.

In smoking the usual form of pipe comprising a bowl and a stem with a hole through the stem to the bowl, the smoker'finds that the bowl becomes hot and thehole in the stem clogs up. In addition, after a period of time the pipe cakes and unless the cake is cut out eventually causes a breakage of the bowl.

One of the objects of this invention is to decrease the temperature. of the outer walls of the bowl. Another object of the invention is to prevent radiation of heat to a smoke well below the tobacco bowl. Still another object of the invention is to provide a pipe that will smoke satisfactorily at a low cost of manufacture. A further object of the invention is to provide a'pipe that can be easily cleaned and one that will not cake although smoking in a cool manner similar to a well caked pipe. Still other objects of the invention are to provide a pipe that will retain the heat within the inner bowl to more entirely consume the tobacco and be sanitary at the same time and give a cool, clean smoke.

Referring to the drawing:

Figure 1 is a longitudinal sectional view partly in elevation embodying the principles of my invention.

In carrying out my invention, I propose to make the bit preferably of hard rubber although any of the well known materials of which pipe bits are made can be used. A hole or smoke conduit 2 is drilled therethrough in the usual manner and bit 1 is preferably made tapered as at 3 to fit within the protruding stem 4 from the pipe. I also propose to make the pipe proper of clay which comprises an inner bowl 5 terminating at the top in a collor 6 and having a passage 7 from the bottom thereof to smoke well 8. Adjacent bowl 5 is bowl 9 made principally of magnesium. Around bowl 9 is the pipe body 10 formed of two parts, 10 andlO. The body part 10, contains within itself bowls 5 and 9. The three bowls 5, 9, and 10, are pressed into an integral'unit while in a plastic state and then glazed or vitrified both inside and outside to make the unit non-porous. The lower part 10 is likewise glazed or vitrified to make it non-porous. The lower portion 10 contains 1926. Serial No. 100,484.

smoke well 8 and pad 11 which may be of antiseptic material. The lower portion 10 is made integral with the stem 4. tion 10' and lower portion 10 together at 12.

The inside of bowl 5 is preferably glaze-cl to prevent burning or charring and its satura tion with nicotine. It will be noted that such construction prevents the formation of heels of saturated tobacco or the formation of cakes in the bowl. 7

The inner bowl 9 of magnesium reduces the radiation and transfer of heat from bewl 5 to the outer portions 10, 10", and smoke well 8. 7

Smoke well 8 not only operates as a coolingchamber, but also prevents moisture from the mouth from reaching the tobacco and such moisture is absorbed by pad 11. The glazing of the walls of smoke well S'prevents the abare threaded Upper porsorption of moisture making the pipe more sanitary. I

The tobacco burning in bowl 5 radiates the majority of its heat outof the top of the pipe giving a more satisfactory smoke. The clay pipe can be colored or decorated exteriorly with artistic designs and glazed if desired.

It will thus be seen that I have invented a pipe that can be readily cleaned by the flushing with water or, if desired, can be taken apart and easily cleaned and one that is cheap to manufacture, giving a satisfactory, pure, clean and cool smoke.

What I claim is:

1. A claypipe comprising a bit, a stem and a bowl, said bowl formed into an integral unit from three bowls while in a plastic state, said bowl comprising an inner clay bowl glazed on the inside, an outer clay bowl glazed on the outside, a magnesium bowl between said inner and outer bowls, a smoke passageway from said inner bowl through said outer bowl, stem and bit.

2. A clay pipe comprisingin combination a bit, a stem, a body portion formed in the plastic state of three bowls into an integral unit and glazed internally and externally, said body portion consisting of an inner bowl, an outer bowl, and a lining between said inner and outer bowls of heat insulating material.

3. A clay pipe comprising a bit, a stem and a body portion, said body portion separable from said stem and adapted to be threaded therein, said body portion formed in the r" plastic state into an integral unit of three bowls, said bowls comprising an inner bowl and a bowl of heat insulating material between said inner and outer bowls, said body portion glazed internally and externally,

said stem glazed internally and externally, a

smoke passage between saidbody portion and said stemrand a smoke passage through said stem and said bit.

4:. A clay pipe comprising a bit, a stem and a bodyportion, said body portion separable from said stem and adapted to be threaded therein, said-body portion formed in the plastic state into an integral unit of three bowls,'said bowls comprising an inner 0 bowl and a bowl of heat insulatingmaterial between said inner and outer bowls, said body portion glazed internally and externally, a smoke well in said stem, a smoke passage from said body portion to said smoke well,

a smoke passage through said stem through said smoke well communicating with a smoke passage in said bit, said stem glazed internally and externally.

5. A clay pipe comprising a bit, a stem and a body portion, said body portion separable from said stem and adapted to be threaded therein, said body portion formed in the plastic state into an integral unit of three bowls, said bowls comprising an-inner ii-owl, an outer bowl and a bowl of heat insulating material between said inner and outer bowls, said body portion glazed internally and externally, a smoke well adapted to receive an asbestos pad, an asbestos pad 7 for said smoke well, a smoke passage from said body portion to said smoke well, a smoke passage from said smoke well through said stern and communicating with a smoke pas- V sagein said bit, said stem glazed'internally and externally.
