United States Patent 3,292,638 SMOKING PIPE Claude Lorquet, 370 Sunset Drive, Hamburg, N.Y. 10115 Filed June 8, 1964, Ser. No. 373,334 3 Claims. (Cl. 131183) This invention relates to smoking pipes and particularly to a supporting and ejecting means for the tobacco in the pipe bowl.

In the prior art various ejecting devices for the used tobacco or dottle in a pipe bowl have been proposed. The present invention provides an improved device of this general character which, in addition to its ejecting function, forms a leak-proof moisture receiving well in the bottom of the pipe bowl.

Furthermore, the device of the present invention provides a support for the tobacco which retains the same above the level of the bore which discharges into the bowl from the stern of the pipe. Thus the full charge of tobacco is maintained in a clean, dry condition until it has been fully consumed.

In addition to the foregoing the present invention provides an ejector seal construction which may readily be applied to smoking pipes of conventional construction and which is so arranged that the seal element thereof may be readily replaced if such replacement becomes necessary. Other objects and advantages of the device of the present invention will become apparent to those skilled in the present art from a perusal of the following specification and the accompanying drawing.

While a single specific embodiment of the principles of the present invention is illustrated in the accompanying drawing and described in detail in the following specification, it is to be understood that such embodiment is by way of example only and that various mechanical modifications may be made without departing from the spirit of the invention, the scope of which is limited only as defined in the appended claims.

In the drawing:

FIG. 1 is a partial longitudinal cross sectional and elevational view through a smoking .pipe provided with one form of the tobacco supporting and ejecting device of the present invention; and

FIG. 2 is a top plan view of the ejecting device portion of the structure of FIG. 1.

In the drawing like characters of reference denote like parts and the numeral designates generally a smoking pipe having a bowl 11 and a stem 12. In FIG, 1 the tobacco receiving chamber of the bowl is designated 13 and the communicating bore in the stem is designated 14.

In applying the device of the present invention to the foregoing conventional smoking pipe the bottom of the pipe bowl is bored to slidably receive a rod 15 and the bore is counterbored and internally threaded at its lower end as indicated at 16 in FIG. 1. An O-ring 17 is placed in the counterbore about the rod 15 and an annular screw 18, likewise disposed about rod 15, is tightened against the O-ring to flatten the same as indicated in FIG. 1. The proportions of the O-ring are such that pressure of screw 18 thereagainst urges the internal periphery of the O-ring against rod 15 to permit sliding movement and to seal the same so that moisture in the bowl will not leak downwardly past the rod 15.

In FIG. 1 the supporting and ejecting device is shown in its normal operating position and a disc 20 is fixed to ice the upper end of rod 15, as by riveting the upper end of the rod over the disc 20. It will be noted that disc 20 is of such diameter that, in its lowermost operating position, it engages and seats against the interior wall of bowl 11 above the level at which bore 14 enters the chamber 13.

Disc 20 is perforated as shown at 21 in FIG. 2 to permit free passage of air and smoke. A spacing sleeve or ferrule 22 is disposed about rod 15 between disc 20 and the bottom of the chamber 13. A manipulating button 24- comprises a disc which is threaded to the lower end of rod 15. When the contents of chamber 13 are to be discharged the pipe is merely turned over and button 24 is depressed to move disc 20 toward the top of bowl 11. The natural taper of the wall of chamber 13 of the bowl 11 allows the accumulation of a desired cake formation on the chamber wall.

The frictional fit of rod 15 in the seal formed by O- ring 17 is preferably sufficiently tight to avoid inadvertent movement of the rod 15 so that the contents of the pipe will not be discharged accidentally. This relatively close fit also permits the button 24 to be used as a rest for the pipe to support the same in upright position on a table or the like.

I claim:

1. In a smoking pipe comprising a bowl having a tobacco receiving chamber having upwardly and outwardly tapering wall portions and a stem having a passage communicating with the lower portion of said chamber, said bowl having a vertical central bore through its bottom and a rod slidable vertically therein, a perforated disc fixed to the upper end of said rod within said chamber above said passage, and an operating button fixed to the lower end of said rod, said vertical bore having an internally threaded counterbore in its lower end and having a downwardly facing annular shoulder, a compressible annular seal in said counterbore and an annular screw disposed about said rod and threaded into said counterbore to compress said seal against the shoulder and urge the same radially inwardly against said rod sufiiciently to seal the same against leakage and to permit said rod to he slid with respect to the seal and screw to move said disc from a lower tobacco supporting to an upper disdischarging position.

2. In a smoking pipe comprising a bowl having a tobacco receiving chamber having upwardly and outwardly tapering wall portions and a stem having a passage communicating with the lower portion of said chamber, said bowl having a vertical central bore through its bottom and a rod slidable vertically therein, a perforated disc fixed to the upper end of said rod within said chamber above said passage, and an operating button fixed to the lower end of said rod, said vertical bore having an internally threaded counterbore in its lower end and having a downwardly facing annular shoulder, a compressible annular seal in said counterbore and an annular screw disposed about said rod and threaded into said counterbore to compress said seal against the shoulder and urge the same radially inwardly against said rod sufliciently to seal the same against leakage and to permit said rod to he slid with respect to the seal and screw to move said disc from a lower tobacco supporting to an upper discharging position, said disc being proportioned to engage the inner wall of said bowl above said passage when in its lower position and movable upwardly by pressure against said operating button to eject the contents of said bowl.

3. In a smoking pipe comprising a bowl having a tobacco receiving chamber having upwardly and outwardly tapering wall portions and a stem having a passage communicating with the lower portion of said chamber,

said bowl having a vertical central bore through its bot tom and a rod slidable vertically therein, a perforated disc fixed to the upper end of said rod within said chamber above said passage, and an operating button fixed to the lower end of said rod, said vertical bore having an internally threaded counterbore in its lower end and having'a downwardly facing annular shoulder, a compressible annular seal in said counterbore and an annular screw disposed about said rod and threaded into said counterbore to compress said seal against the shoulder and urge the same radially inwardly against said rod sufficiently to seal the same against leakage and to permit said rod to be slid with respect to the seal and screw to move said disc from a lower tobacco supporting to an upper discharging position, a spacing sleeve disposed about said rod within said bowl and beneath said perforated disc to establish a lower limit position of said disc, said lower limit position being above said stem passage.
