Stone holding downstem end

Abstract

The stone holding downstem end is a modification to a standard downstem end to enable it to hold a porous stone. A standard downstem end is a full circle and only allows the stone to be heated from above. By subtracting material from the receiving end of the downstem we create a new downstem end that is not receptive to a standard bowl anymore, but is instead specially modified to hold a porous stone. With the modification the user can heat the stone from the side rather from just above. This increases the potential for material to be vaporized and less chance for the material to melt through.

Claims

1. A bowl receiving end of a downstem consisting of: a tube such that said tube has a subtraction section starting from the receiving end of the tube; said subtraction is less than 50% of the arc of the circumference of the tube.

2. A bowl receiving end of a downstem consisting of: a tube such that said tube has 2 or more non-adjacent subtraction section starting from the receiving end of the tube; said subtractions have subtraction depths less than the length of the tube and have individual subtraction arcs less than 50% of the circumference.

3. The invention in claim 1 where the subtraction depth equals the full length of the tube.

4. The invention in claim 1 where the subtraction depth is less than the length of the tube.

DETAILED DESCRIPTION OF HOW THE INVENTION WORKS

[0011] The invention is a new form of the bowl receiving end of a downstem for a waterpipe. The bowl receiving end of a downstem for a waterpipe is commonly constructed independently and then attached to another simple tube to create the downstem. The method of attaching of these two pieces together to create the downstem varies depending on the materials being used. The current invention does not depend on the materials being used or the method of attachment, but rather the change in form of the bowl receiving end of a downstem to create increased utility in the consumption process of marijuana concentrates.

[0012] Drawing 1 is an illustration of the invention with a partial length subtraction 1. The subtraction depth 3 the and the subtraction arc 2 describe the volume to be subtracted. The bottom end 11 has a standard finish, dependent on materials used, such that it can be can be attached to the corresponding tube material to form a complete downstem.

[0013] Drawing 2 is an illustration of the invention with a partial length subtraction 1,4 fitted with a porous stone 5. The subtraction depth 3 should be deep enough so that the porous stone 5 sits inside the bowl receiving end of the downstem 1,4 and within the section containing the subtraction while seeking to minimize the stone gap 6. The angle of the subtraction arc 2 is important. The subtraction arc 2 must be less than 180 degrees but greater than 0 degrees. A practicable angle for the subtraction arc 2 would reside between 45 degrees and 60 degrees. The subtraction arc define how much of the porous stone 5 will be exposed for heating from the side when added. The porous stone 5 is natural held in position in the bowl receiving end of the downstem 1,4 with friction due to the diameter of the porous stone 5 and the diameter of the bowl receiving end of the downstem 1,4. The bowl receiving end of the downstem 1,4 can have either a constant diameter or a dynamic diameter where the receiving end has a larger diameter than the dispensing end. This means the invention should be constructed with a specific porous stone 5 diameter in mind, but a bowl receiving end with a dynamic diameter will allow for more variance in the porous stone 5 diameter.

[0014] Drawing 3 is an illustration of bowl receiving end of the downstem with a full length subtraction 7. Since the bowl receiving end of the downstem 1,4,7 needs to be attach to another tube at the bottom end 11,12 to complete the downstem, it may be easier (depending on materials and corresponding subtraction methods) to make the subtraction depth 3,8 the entire length of the bowl receiving end of the downstem 1,4,7. Drawing 4 is an illustration of bowl receiving end of the downstem with a full length subtraction 7,9 fitted with a porous stone 5,10. The porous stone 5,10 is again held in place by friction, but now there is no stone gap 6 to worry about. Instead of design at aiming to minimizing the stone gap 6, the design should aim to set the stone near the bottom of the bowl receiving end of the downstem with a full length subtraction 7,9.

[0015] An alternative form of the invention is to utilize more than one subtractions to increase the range of angles that the stone maybe heated from. When performing multiple subtractions each individual subtraction arcs must be less 180 degrees. Drawing 5 is an illustration of an example of a stone holding downstem utilizing two subtractions 13. Drawing 6 is an illustration of an example of a stone holding downstem utilizing two subtractions 13,14 fitted with a porous stone 5,10,15. Drawing 7 is an illustration of an example of a stone holding downstem utilizing three subtractions 16. Drawing 8 is an illustration of an example of a stone holding downstem utilizing three subtractions 16,17 fitted with a porous stone 5,10,15,18.

[0016] The invention is the new form of the bowl receiving end of the downstem 1,4,7,9. This form is reachable through subtractive methods applied to current forms of bowl receiving ends of downstems. This form can also be reached by utilizing additive methods such as 3d-printing. Glass is a popular material for downstems. Standard glass bowl receiving ends of downstems can easily be modified using subtractive methods by a person skilled in the field of glass manufacturing to produce the invention, stone holding downstem end 1,4,7,9.
