PIPE

Filed March 31, 1955 II III I) v INVENTOR. SEWARD P. REESE (EWMJMW ATTORNEYS United States Patent PIPE Seward P. Reese, Salem, Oreg.

Application March 31, 1955, Serial No. 498,159

2 Claims. (Cl. 131-213) The present invention relates to a smokers pipe, and more particularly to an improved construction for providing clean, cool smoke.

Various oils and tars are distilled from tobacco as the tobacco burns in a pipe. There are indications that such distillates are injurious to the health of the smoker if he inhales the same, and at least some of the distillates impart a bitter or acrid taste to the smoke if they are carried with it to the smoker. It is an object of the invention to provide a new and improved pipe construction capable of extracting such tars and oils from the tobacco smoke.

More particularly, it is an object of the present invention to provide a pipe of the type described of simplified construction whereby it may be manufactured at relatively low cost.

It is another object of the invention to provide a pipe of the character described which may be easily assembled for cleaning and reassembled thereafter.

Other objects and advantages of the invention will become more apparent hereinafter.

In accordance with the illustrated embodiment, the pipe of the invention comprises a stern comprising a plurality of tubes through which the smoke is drawn in series so as to provide an elongate passage for the smoke for cooling the same and for condensing tars and oils therefrom. The pipe bowl is mounted on a cup formed in one end of the stem, the latter providing a large collection chamber for the condensed tars and oils.

For a more detailed description of the invention, reference is made to the accompanying drawings wherein:

Fig. 1 is a side elevation of the pipe;

Fig. 2 is an exploded perspective view of the pipe of the invention;

Fig. 3 is a vertical, sectional view through the bowl and pipe stem;

Fig. 4 is a horizontal, sectional view through the stem; and

Fig. 5 is a bottom plan View of the pipe bowl.

The pipe of the invention comprises a tobacco holding bowl preferably formed of wood. Secured to the bottom of the bowl 10 is a circular metal plate 11 having threads 12 on the periphery thereof, the plate 11 being recessed for receiving an extension 14 formed on the bottom of the bowl. Spurs 15 are provided on the plate 11 for engaging in notches 16 in the bowl 10 to secure the plate from rotation relative to the bowl. The plate is removably attached to the bowl 10 by means of a headed screw 17 which extends downwardly through an aperture 18 formed in the bottom of the bowl 10 and is threadedly engaged in a tapped aperture 19 formed in the plate 11. The screw 17 extends below the plate 11, for reasons to be explained, and is provided with a coaxial bore 20 through which smoke may pass from the bowl 10.

The bowl assembly just described is mounted on a stem including a cup 24 formed of an aluminum alloy and provided with internal threads 25 for engaging the ice threads 12 of the plate 11 whereby the bowl assembly may be releasably mounted upon the cup. The side walls of the cup are formed with a circular ledge 26 against which the plate 11 abuts when mounted on the cup. Extending across the cup is a dividing wall 27, the

top edge of which is adapted to abut the bottom of the 1 plate 11 when the latter is mounted on the cup so as to provide two separated chambers 28, 29in the cup. As shown most clearly in Fig. 4, the screw 17 extends downwardly into the chamber 29 with the lower end of the screw spaced above the bottom of the chamber whereby smoke is free to pass from the bore 20 into the chamber 29. Extending side by side from the cup 24 are three parallel tubes 30, 31 and 32 also formed of an aluminum alloy. The tube 30 is arranged for communication with the chamber 29, while the tubes 31, 32 are arranged for communication with the chamber 28.

Mounted on the end of the tubes remote from the cup 24 is a bit assembly including a generally cylindrical bit block 35. The block 35 encloses the tubes 30, 31, 32 at the end of the block facing the cup, the opposite end of the block being formed with an inwardly tapering opening 34 in which is received one end of a bit or mouthpiece 36 having a bore 37. The end of the mouthpiece 36 received within the bit block 35 is cooperatively tapered so as to form an air tight closure with the bit block and also so that the mouthpiece is held in spaced relation from the bottom of the opening of the bit block. The central tube 31 extends into the bit block opening 34 and is received cooperatively within the bore 37 of the mouthpiece 36, an O-ring 38 being mounted in the mouthpiece bore to engage the tube 31 to form an airtight seal thereabout. The outer tubes 30, 32 terinate short of the bottom of the bit block opening 34, passageways being provided through the block to provide communication between the tubes 30, 32 and the opening 34. Thus the opening 34 provides a passageway for smoke to travel from the tube 30 to the tube 32 when the pipe is smoked as will now be described.

When the smoker draws upon the mouthpiece 36, smoke will be drawn downwardly from the bowl 10 through the bore 20 of the screw 17 into the compartment or chamber 29. From thence it will travel through the tube 30 into the bit block opening 34 and across the same to the tube 32 and back to the cup chamber i 28. From the chamber 28 the smoke will be drawn through the center tube 31 and through the bore 37 of the mouthpiece 36.

The cup 24 and the tubes 30, 31, 32 provide a relatively cool surface upon which will condense the oils and tars normally distilling from the burning tobacco smoked in the pipe, so that such distillates are not inhaled by the smoker. Preferably aluminum or an aluminum alloy is used for these parts so that the pipe will be of light weight and also because the relatively great heat conductivity of aluminum will help in the dissipation of the heat so that the condensing surfaces will remain relatively cool and efl'ective.

The screw 17 preferably extends downwardly below the plate 11 to prevent any liquids which may be condensed in the chamber 29 from flowing into the bowl 10 when the pipe is inverted to knock ashes from the bowl. The metal bowl mounting plate 11 is of advantage for two reasons. Since it is not subject to warpage, as is the wood of the pipe bowl 10 because of continual change in the moisture content thereof, a constant snug fit is assured between the plate 11 and the ledge 26 and dividing wall 27 whereby the smoke from the bowl must pass through the three tubes 30, 31, 32 before it is inhaled by the smoker. Also, the plate threads 12 resist wear, whereas if threads were formed directly in the wood of the bowl it is probable 3 that the frequent removal ofthe bowl would cause such threadsto wear out within .a ,short time and thus destroy the usefulness of the bowl.

It will be apparent that the pipe may be easily and quickly taken apart for cleaning and that all of the parts and surfaces may be easily and quickly cleaned.

Having illustrated and described a preferred embodiment of the invention, it shouldbe apparent to those skilled in the art that the invention permits of modification in arrangement and detail. I claim as my invention all such modifications as come within the true spirit and scope of the appended claims.
