Description

United States Patent 3,209,765 SMOKERS ACCESSORY James Y. Shih, 819 Aldine Ave., Chicago 13, Ill. Filed Aug. 8, 1963', Ser. No. 300,945 4 Claims. (Cl. 131-173) This invention generally relates to smoking pipes and more particularly a pipe having a water filter which is capable of being converted from a water filtering pipe to a direct smoking pipe having no filter.

One object of the invention is to provide a pipe which has very cool smoke to protect mouth tissue.

Another object of the invention is to provide a pipe with a water filter which can remove most the condensation from smoke and prevent it from reaching smokers mouth.

Still another object of the invention is to provide a water pipe with a safety valve to prevent any leakage of water.

These, together with other objects and advantages which will become subsequently apparent, reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a central longitudinal section through a pipe constructed according to the invention, portions of the bowl and of the stem being shown in elevation.

FIGURE 2 is a cross-sectional view taken along the line A-A of FIG. 1.

FIGURE 3 is a cross-sectional view similar to FIG. 2, but showing a valve position of a direct smoking pipe.

FIGURE 4 is a perspective view of the bowl element.

FIGURE 5 is a perspective view of the smoking pipe.

FIGURE 6 is a top view of the smoking pipe.

In carrying out the invention, referring now specifically to the drawing, there is provided a stem 1 having its lower end 1a fitting in a cylindrical bore 1b in the top of the body 3, and the stem 1 is horizontally turned at 10 so that the tip 19 of the stem extends horizontally. The body 3 comprises a container having an upper wall 3a which is thicker than the other walls, such as side wall 3b and bottom wall 30. The upper wall 3a has a cylindrical bore 18, fitting the shaft 14 which is carried by the lower end of the bowl 6, thus supporting the bowl 6 on the body 3. The upper Wall 3a of body 3 has a smoke passage 7 which extends from the upper end of bore 1b through upper wall 3a to bore 18 with which passage 7 communicates tangentially as seen in FIGURE 2 and FIGURE 3. The body 3 is provided with a water chamber 20 which is bounded by upper wall 3a, side walls 3b and bottom 30. The water level in the water chamber 20 is below the baffle 13. The bowl 6 comprises a friction fit shaft 14 fitting in the bore 18. The shaft 14 has a transverse bore for receiving a smoke by-pass valve shaft 150 which has a screw driver slot 15b at one end and supports a valve disc 16 at the other end in bore 17. Bore 17 extends inwardly from the flat side 21 of shaft 14 and emerges at right angles at bore 10b of cavity 11 of shaft 14. The valve tip 15 may be turned by inserting a screwdriver in slot 15b to turn valve disc 16. The bowl 6 comprises a cylindrical bowl having an inner bore 6a, having a partially spherical bottom 6b with a central downwardly extending bore 60 communicating with

bores

17 and 10b.

In the operation of the device the stem 1 is the smoking tip. When the bowl is in the position shown in FIGURE 1, the sucking action at tip 19 of the stem 1 produces low pressure in the water chamber 20. The smoke from burning tobacco in bowl 6 will then travel through

passages

10b and 9 into the tubing 8. At the end 12, the smoke bubbles into the water filter in the water chamber 20. The filtered smoke will then travel through passage provided 3,209,765 Patented Get. 5, 1965 "Ice by the side 21 into passage 7 and enter smokers mouth. The baffle 13 in the water chamber 20 breaks the bubbles caused by the passage of smoke and prevents water from entering the smoke passage provided by the side 21. Should partially water filtered smoke be desired, bowl 6 can be removed andby-pass valve tip 15 can be adjusted with an ordinary small screw driver. Should full water filtering be desired, the by-pass valve canbe adjusted one hundred percent shut(circular disc closes passage 17). Any proportion of mixed smoke can be attained by adjusting the by-pass valve zero to ninety degrees. In addition to the foregoing adjustment, the proportion of mixed smoke can also be adjusted by the inter-mediate positions of the bowl between the two extremesshown in FIGURE 2 and FIGURE 3 when the by-pass valve is not provided or fully closed. The arrow 5 on the bowl 6 and suitably located

letters

22 and 23 on the body indicate the function (or proportion of filtered and unfiltered smoke). FIGURE 3 shows the location of parts when the pipe is used as a direct smoking pipe. For refilling water, one can remove bowl 6 and stem 1, drain the used water and refill with clean water. The loading of tobacco can. be performed by removing the bowl 6, load it with tobacco and placing it back. Indicating

letters

22 and 23 on the top surface of body 2 and arrow 5 on bowl 6 are for functional alignment.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

Having thus completely and fully described the invention, what is now claimed as new is as follows:

1. A smoking pipe comprising in combination, a supporting body having an upper wall, side walls depending from the upper wall, and a lower wall, said. walls forming a water chamber, and said upper wall supporting a depending tubular conduit extending below the water level of said water chamber, said upper wall having a first cylin' drical stem supporting bore at one end of the top wall, and a second cylindrical bowl supporting bore at the other end of said top wall, said stem supporting bore being closed at its lower end and communicating with a smoke passage in said upper wall at a point spaced from the bottom of said stem supporting bore, forming a condensation trap in the lower part of said latter bore, a stem carried by said supporting body and having its lower end frictionally secured in said first bore with the end of the stem located above the adjacent end of said smoke passage, said stern having a smoke passage extending therethrough from the first bore to the open upper end of said smoke passage in said stem, said second bore being defined by a cylindrical wall vertically disposed in said body supporting an extending bowl having an external cylindrical shape and an internal cylindrical bore, rounded at the bottom, and provided with a central smoke discharge aperture in an axial shaft fitting in said second bore frictionally and securing the bowl in the body, said shaft having a transversely extending passage, communicating with said smoke passage in the top wall of the body at one end and with the smoke discharge aperture of the bowl at the other end, whereby the smoker may draw smoke through the smoke passage of said stem, through said condensation trap, through said smoke passage in the upper wall and through said transversely extending passage in said shaft, and through said smoke discharge aperture of said shaft, from said bowl, when said transverse passage in said shaft is in communication with said smoke passage, said bowl shaft being releasable from its frictional engagement in said second bore and rotatable into a position where the transverse passage of said shaft is closed against water leakage from said water chamber.

2. A smoking pipe as set forth in claim 1, said second bore also communicating with a second transverse passage in said shaft extending to another smoke passage in the upper wall leading to the upper end of said smoke tube depending into the water chamber, and said shaft having a flat side forming a downward passage to its lower end communicating with the upper end of the water chamber, said second bore having a transverse bafile at its lower end for limiting the movement of water upward into the second bore, the said pipe being usable as a pipe with direct connection between stem and bowl or as a water filter pipe directing the smoke through the water to the stem upon rotation of the shaft into a position of communication of said smoke passage and said transverse passage.

3. A smoking pipe as set forth in claim 2, said transverse passage in said shaft having a valve disc therein, mounted upon a turning tip accessible by a screwdriver in- 20 sertable into said transverse bore to position the valve disc to cut off the transverse passage to the water chamber or to regulate the mixture of water filtered smoke and smoke directly from the bowl.
