United States Patent O 2,772,680 SMOKING DEVICE George W. Rehfeld, Manhattan, Kans. Application April 26, 1952, Serial No. 284,537 2 Claims. (Cl. 131-182) This invention relates to tobacco smoking devices of the type including a tobacco receptacle, and a stem and mouthpiece interconnected in axial relation therewith. Such smoking devices may require a lter and an insulated tobacco receptacle in order that a cool, clean smoke may be drawn through the` mouthpiece.

In my copending application on Smoking Device, Serlal No. 143,995, now Patent No. 2,617,427, issued November 11, 1952, I have disclosed a tubular stern forming a iilter chamber and which is charged with tobacco from a tobacco receptacle so that the tobacco serves as the ltering material. The pipe structure disclosed in my copending application operates satisfactorily, but care is required in packing the filter chamber in order to provide the proper draft and to prevent spilling of the tobacco from the filter chamber when the ashes are discharged from the tobacco receptacle after the device has been smoked.

It is, therefore, the principal object of the present in- Jention to provide a smoking device of this character with an improved stem and tobacco receptacle to facilitate filling of the filter chamber so that special care need not be required in order to provide the proper draft and so that the tobacco will not be lost from the filter chamber when ashes are expelled from the tobacco receptacle.

lt is an object of the invention to provide the head of the stem with a restricted passageway that tapers reversely to the exterior taper of the stern head.

It is also an object of the invention to provide a structure which facilitates discharge of tobacco from the filter chamber when the Vfiltering material must be replaced.

A further object of the invention is to provide a smoking device of the type described wherein the stem is guided throughout the length thereof when the stem is projected into and retracted from the tobacco receptacle when packing the tobacco and controlling the burning thereof.

Another object of the invention is to provide a head on the stem which forms a wedge type seal with the tobacco receptacle and has a forwardly extending `rim or lip for effecting removal of ashes and caked material from the tobacco receptacle.

A further object of the invention is to provide the head of the stem witha recess in the forward face to receive the end of a cigarette therein.

l'n accomplishing these and other objects of the invention hereinafter pointed out, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawing wherein:

Fig. 1 is a perspective view of a smoking device constructed in accordance with the present invention.

Fig. 2 is an enlarged longitudinal sectional view of the smoking device showing the stem and mouthpiece projected into the tobacco receptacle.

Fig. 7 is a perspective view of the mouthpiece and stem of the device shown in Fig. 1, the mouthpiece being shown as removed from the stem.

Referring more in detail to the drawings:

1 designates a smoking device embodying the features of the present invention and which includes a substantially elongated cylindrical tobacco receptacle 2, a stem 3 and a mouthpiece 4, all mounted in interconnected axial alignment. The receptacle 2 includes a wall 5 formed of a tubular section of insulating material such as a heat resistant synthetic plastic and having open ends 6 and 7 to receive therein end members 8 and 9. The end members 8 and 9 are preferably formed of light-weight material such as aluminum alloy and have cylindrical portions 10 and 11 that are pressed tightly within the tubular section whichy forms the insulating wall 5.

The member 8 has a portion 12 that tapers inwardly toward the axis of the members to provide an opening 13 of a diameter adapted to pass the stem 3. The end member 9 has a portion 14 which is open toward the stem end as indicated at 15. It is obvious that the tobacco space 16 in the receptacle 2 thus formed extends the full material such as aluminum alloy and includes a cylindrical portion 17 having a sliding fit within the opening 15. The stem also includes tapered portion 18 corresponding with the tapering portion 14 of the end member 9 to fit therein and provide a wedge-tight seal when the stem is in the position as shown in Fig. 4.

An insert 19, which may be of non-metallic material, is applied within the tapered portion 18 of the stem. The insert 19 has a tapered axial recess 20. The recess 20 communicates with the relatively small axial smoke passage 20 which communicates with a recess 21 in the outer end of the insert 19. The larger end of the axial recess 20 corresponds with the inner diameter of the stem while the smaller end is approximately the diameter of the smoke passageway 20 to cooperate therewith in providing for passage of smoke therethrough and to limit spilling of tobacco from the stem into the smoking space that is provided in the smoke chamber of the tobacco receptacle 2 when the tobacco receptacle is loaded as later described. The insert 19 is pressed into the internal taper of the stem and gives added wall thickness to provide an annular tamping face 22 for tamping tobacco in the tobacco receptacle. The axial recess 21 may be used to receive the end of a cigarette so that the smoking device may be used as a cigarette holder if desired.

The insert 19 may be of a size to permit slight forward projection of the stem to provide an annular scraping lip or rim 23 to facilitate discharge of tobacco from the tobacco chamber.

The opposite end of the stem has a tapered counter- 1 bore 24 to frictionally receive a tapered end 25 of the Fig. 3 is an end View ef the tobacco charging end of mouthpiece 4. The mouthpiece 4 may be substantially conventional shape and the end 25 closes the adjacent end of the stem. The stem provides a filter `chamber 26 having its outer end defined by the insert 19. The filtering material 27 to be contained in the filter chamber may be loosetobacco (Fig. 4).

` The mouthpiece 4 has a smoke passageway 28 that connects with the filter chamber 26 and which extends l through the bit 29 of the mouthpiece. The bit 29 of the receptacle of the device shown in Fig. l, parts of the i smoking device shown in spaced coaxial relation with portions of the partsbeing broken away and in section to better illustrate the construction thereof.

` Fig. 6 is a View of the mouthpiece end of the smoking device shown in Fig. l.

mouthpiece preferably has a transverse width slightly greater than the inner diameter of the smaller end of the member 9 so that when the stem and mouthpiece are in telescoped relation with respect to the tobacco receptacle, the stem and mouthpiece are retained therein but are adapted to be slid through the tobacco receptacle when pressure is applied in the longitudinal direction of the mouthpiece to force the side edges 36 and 31 of the bit 29 through the smaller end of the tapered portion 1,4, the end member 9 being of suiicient resiliency to allow the slight distortion necessary to permit the side edges 312 and 31 to slide through the small end of the tapered portion 14 when the bit is to be withdrawn from the tobacco receptacle.

In using the smoking device, the mouthpiece 4 is removed from the stem 3 and loose tobacco is inserted into the filter chamber 26 and is packed therein through the open end from which the mouthpiece was removed. The insert 19 at the forward end of `the filter chamber 26 having the tapered recess 2t) therein prevents the tobacco from the discharging from that end of the filter chamber.

The stem may be removed from the tobacco receptacle by sliding the same forwardly through the open end 13 with sufficient pressure so that the side edges 3@ and 31 of the bit portion 29 of the mouthpiece 4 spread the end member 8 sufficiently to allow passage of the mouthpiece portion. After withdrawal of the stem 3 from the receptacle 2, the mouthpiece 4 may be removed and the stem tilled with tobacco through the open end thereof. The mouthpiece 4i is then reapplied and the bit end 29 0f the mouthpiece is reinserted through the forward end of the tobacco receptacle so that the stem and mouthpiece assembly may be slid through the tobacco receptacle for seating the taper 18 of the stem in wedging contact with the tapered portion 14 of the end member 9.

Tobacco is inserted in the tobacco receptacle through the open end 13 after which the charge of tobacco is compressed within that portion of the tobacco receptacle that is surrounded by the end member 8. This is effected by moving the stem assembly forwardly in the tobacco receptacle with the tamping face 22 pressing against the tobaceo` The stem is then returned to again effect a seal of the tapered portion 1S thereof with the end member 9 which leaves a smoke space 32 between the charge 33 of the compressed tobacco within the forward end of the smoking receptacle and the tapered end of the stem (see Fig. 4). The tobacco may then be lighted by applying a tiame at the open end 13 and drawing through the smoke passage 28 of the mouthpiece 4..

After a smoke, the ashes are readily discharged from the end member 8 by pushing the stem 3 forwardly with the face 22 and rim portion 23 thereof pressing the remaining tobacco and ashes through the opening 13. The tobacco forming the filtering material remains in the iilter chamber 26 of the stem and. is not readily displaced therefrom due to the small passageway 29. The smoking device may, therefore, be carried in the pocket without ioss of the tobacco from the filter' chamber. To facilitate carrying of the smoking device when empty, it may be teiescoped as shown in Fig. 2.

When it is desired to replace the filtering material, the stern and mouthpiece assembly are removed through the end 13 as above described, after which the mouthpiece 4 is withdrawn from the stem 3. The filtering material may then be discharged through that end of the stern by blowing through the opening; 2G. The lter chamber of the stem may then be recharged with tobacco, after which the mouthpiece` 4 is again replaced and the assembly is reconnected with the tobacco receptacle Z. They device may be used as a cigarette holder byv pushing the stern through the tobacco receptacle into the position shown in Fig. 2. The end of a cigarette, may then be inserted within the recess 21, after which the stem is moved retractively with respect to the tube receptacle to enclose the cigarette therein while the cigarette is being smoked.
