This invention is in the field of smoking pipes, specifically brass pipes.
The classic smoking pipe is made of hard wood. It is used to smoke dry herbs such as tobacco. The pipe has a bowl to contain the leaves, which are then lit to produce smoke. The smoke is then inhaled through a hollow stem. Modern pipes are made of glass or metal. In addition to dry leaves, modern pipes are also used to smoke vapors from hot oils.
In the 20th century, Phil Jergenson invented the popular brass smoking pipe, the subject of U.S. Pat. D259,587. Jergenson's pipe has a brass bowl for containing dry herbs. The bottom of the bowl is perforated with draft holes. Directly beneath the draft holes is a hollow chamber. The smoke channel leads out of this hollow chamber into the stem. At the bottom of the hollow chamber is a tar trap, which collects gummy residue that drips through the draft holes when the herbs are burned.
One well known problem with Jergenson's pipe is that it is notoriously difficult to remove the tar trap for cleaning. The tar glues the trap into place. Another problem is that the pipe tarnishes over time. Further, the pipe is a product of earlier times when herbs were harder to clean. The draft holes are limited to 1/16″ in diameter in order to keep dirt from falling into the hollow chamber. The small draft holes limit the pipe's airflow capacity, known in the art as the draw.
The present invention is a modification of Jergenson's pipe with several improvements. It is nickel-and-brass plated to prevent tarnishing. It has enlarged draft holes and an enlarged tar trap for increased draw. The invention provides a groove and O-ring around the tar trap for greater ease of removal and cleaning.
A quartz crystal bowl is provided. The quartz crystal bowl is useful for smoking dry herb, oil, or oil-infused herb. The invention provides a plurality of quartz crystal bowls, which fit inside the storage chamber as a cartridge. Other improvements will be presented in detail below.
Each part of the invention is numbered with a digit that indicates the figure in which the part first appears. For example, part 221 first appears in
The invention is a modified brass smoking pipe. Production begins with a standard solid brass pipe 11, ideally Jergenson's pipe or a similar article. The essential parts of the unmodified pipe are a brass bowl 111 with a central draft hole 1111 and peripheral draft holes 1112, a mouthpiece 112, a storage canister 113, a removable poker 114 that fits into a poker stem 23, a hollow chamber 21 beneath the brass bowl, and a removable tar trap 22 that fits within the hollow chamber.
The improved pipe is coated with a plate of nickel, which is then plated with another layer of brass. This plating is enough to keep the pipe from tarnishing.
The draft holes in a standard brass pipe are 1/16 inch in diameter. This is a holdover from days when available herbs were dryer and dirtier than today (about 5% dirt by volume). With today's cleaner product, the pipe can function with larger holes. The next modification is to use a drill to expand each draft hole 1111 and 1112 to a diameter of 3/32 inch. See
The tar trap 22 is a solid brass plug that is concave on top to collect tar from burning herbs. The next major improvement in the current invention is a deepening of the tar trap.
Note that the deep-dish concavity 412 sits essentially below the smoke hole 221. This keeps smoke and tar from seeping out of the tar trap into the hollow chamber 21. In Jergenson's pipe, this seepage creates a layer of residue around the tar trap, gluing the tar trap into the hollow chamber.
The improved tar trap is modified to fit better into the hollow chamber for easier insertion and removal. Jergenson's tar trap is tapered and then press fit into the hollow chamber. By contrast, the modified tar trap has a vertical external wall 223. The external wall has a circumferential groove 51. An O-ring 222 fits into the circumferential groove 51. The O-ring provides a tight seal for the tar trap when it is inserted into the hollow chamber. Because of this seal, it is not necessary to press fit the modified tar trap into the hollow chamber. The tar trap is removed for cleaning much more easily.
The poker 114 is a multi-functional tool. Normally, it fits in place on the underside of the pipe, as shown best in
Jergenson uses only a straight steel wire to hold the tar trap in place. The improved pipe has an enlarged poker 114. A second end 25 of the poker 114 protrudes into the hollow chamber 21, as visible in
The poker is also used to remove the tar trap. The second end 25 of the poker 114 fits through the central draft hole 1111 of the brass bowl and pushes down on the tar trap 22. This action easily removes the tar trap. The same action is notoriously difficult for Jergenson's pipe. Jergenson's tar trap is press fit. Furthermore, without the O-ring, Jergenson's tar trap tends to get completely glued into the hollow chamber with tar.
In an alternative embodiment (not shown in the figures) the poker may take the form of a hex key or Allen wrench, with a 90° bend in the first end 1141. The 90° bend replaces the grip nut. In this embodiment, the second end 25 has a hexagonal cross-section. The hexagonal cross-section fits into the screw 115 to adjust the screw more loosely or tightly. The screw, in turn, secures the lid 116 of the pipe.
The poker may be formed of brass or a material with a high melting point such as grade 2 titanium or quartz crystal glass. Brass, titanium, and quartz crystal glass have melting points above 1,600° C. A heat-resistant poker is useful when the poker is used to dab concentrates.
Some smokers prefer to keep their herb in a quartz crystal bowl 24. The quartz crystal bowl is made of quartz crystal glass. It fits inside the brass bowl, as shown in
The improved invention modifies a brass pipe to serve as a concentrate pipe. A concentrate is an herbal oil made into a concentrated wax or liquid. For example, e-juice is a tobacco concentrate used in e-cigarettes. To set up the pipe to smoke concentrate, a retaining rod 81 is fitted through the central draft hole of a quartz crystal bowl as seen in
A push nut 82 is provided to facilitate holding a quartz crystal bowl 24 on a retaining rod 81. A push nut is a washer with a concave face 821 and a convex face 822 (not shown directly). The washer is perforated with a central hole 823. The configuration of the push nut makes it unidirectional. When a push force is applied to the convex face, the central hole is slightly opened, allowing the push nut to slide along the rod in the direction of its concave face. However, when a push force is applied to the concave face, the central hole is slightly closed, making the push nut seize up on the retaining rod. In this regard, the push nut is like a Tinnerman washer.
The push nut provides support for one or more quartz crystal bowls on a retaining rod.
