Referring more in detail to the drawings:
l designates a smoking device embodying the features of my invention, which-includes asubstantially elongated receptacle 2- formed of any suitable material and-having acylindrical wall 3 open at'oneend to 'provide'a'charg'e opening 4-. The opposite end ofthe cylindrical-receptacle has a taperedend 5 providing an innertapered seat 6 for receiving a stem 1 which telescopes within the receptaclel;
The stem 1 'is cylindrical in formandtapered as illustrated in Figs. 1, 2 and-10. It has an open end B, the outer wall'of which is tapered teen-.- gage the tapered seat 6 of. the cylindrical receptacle 2 to form a substantially air-tight. fit-between the stem and the'receptacle. The steniiis hollow as best illustrated in Fig. 2 and is adapted to receive a bite portion 9 provided-.withan axial bore l0 forming a smoke passageway therethrough, the bite portion being'recessed to fitover the small, tapered end of the stem assindicated at H, Fig. 1, although other forms-may.- be utilized.
I preferably form thehollow stemv'l oftm'etal such as aluminum or. the like,- or'otherrheatconducting material, or itmay be 'madesoiplastic. or other resinous substance; When, the'stem I is made of plastic" or other resinous substance the bite 9 may be formed integral therewith. When the stem is made of aluminum or other similar metal, the bite portion-is removable-therefrom.
The wall of the stem 1 is tapered and the inner thickened end forms a head l2, which may be used for tamping-or packing the tobaccov l3, into the cylindrical receptacle and the hollow stem provides a recess or receptacle; M for tobacco which may be contained therein toform a. fi1tering media in the stem and which loads. itself automatically while the tobacco is being placed. in theranged in an annula r series "intermediate the ends of the open end tubular end or cage member and conform in shape with a plane geometrical figure having greater length than width with the adjacent long sides being sufiiciently close to each other to define long narrow bars extending substantially parallel to the longitudinal axis of the cylindrical end member. The openings allow air to be drawn into the receptacle for promoting burning of the tobacco therein, as well as the retention of the tobacco and ashes. In Fig. 4, the cage is shown to have cylindrical walls 24 and 25 on its respective ends. The lugs 2| are formed integrally with the receptacle wall 3 and are parallel therewith. After the cage is slipped over the end of the receptacle, the lugs are bent outwardly by a suitable tool (not shown) for engaging in the openings 23 as illustrated in Fig. 3 and to retain the cage slidably on the receptacle.
Fig. 6 shows a modified form of cage, wherein the outer cylindrical wall 25 is provided with a plurality of inturned hooks or lugs 26 to further .aid in the retention of the smaller grained tobacco in the receptacle,
In Figs. 8 and 9 I have shown a further modified form of receptacle and cage wherein the outer open end of the receptacle is provided with a laterally turned annular flange 2'! and the respective ends of the wall 28 of the cage 22 are provided with inturned annular flanges 29 and 30. In assembling the device shown in Figs. 8 and 9, the outer, annular flange 30 is not formed until after the receptacle is engaged on the cage. The inner end of the receptacle is inserted through the cage until the flange 21 will engage the flange 29 to retain the cage on the receptacle. The outer flange 30 on the cage is then formed by suitable tools (not shown) by turning the flange inwardly, so as to retain the cage from sliding past the flange 21 of the receptacle. This type cage enables use of large grained tobacco. I preferably cover the cylindrical receptacle 2 with a leather covering as indicated at 3| (Fig. to prevent overheating of the receptacle and thus provide the handling of it by the user more comfortably. The leather is retained on the receptacle by an adhesive material such as glue, and is set back from the open or charge end of the receptacle as indicated at 32 (Fig. 10) so that the cage may slide thereon and the outer end will be substantially even with the end of the receptacle.
In operation of the device with the retractable cage, filling of the receptacle is accomplished by inserting the tobacco through the charge opening of the receptacle with the cage in retracted position andtamping of the tobacco in the receptacle with the finger and forward movement of the stem through the opposite end of the receptacle. The tobacco may be lighted in an ordinary manner and then the cage pulled outwardly over the end of the tobacco receptacle and the device is ready for use. As smoking progresses, the forward movement of the pistonlike head of the stem may move the tobacco, fire and ashes forwardly so that the fire will be maintained substantially in the cage instead of in the receptacle to provide easy burning thereof and stay lighted longer than with ordinary smoking devices due to the air passing through the cage directly to the fire. If desired the cage may be left in retracted position and pushed outwardly by the tobacco engaging the lugs 26 in the case of the end member illustrated in Fig. 6 or the flange 30 in the case of the member illustrated in Fig. 9.
From the foregoing it is obvious that I have provided a smoking device having a relatively small elongated receptacle for containing loose tobacco and which is provided with a cage to retain the tobacco and ashes and which is retractable on the receptacle to permit charging the tobacco without interference by the cage.
What I claim and desire to secure by Letters Patent is: I
1. In a smoking device of the type comprising a cylindrical tobacco chamber, a stem at one end of the chamber and adapted to telescope in the tobacco chamber and a mouthpiece carried by the stem, wherein all of the parts are in axial alignment and in interconnected relation, said tobacco chamber including a cylindrical member completely open at the end opposite said stem and having outwardly extending lugs arranged in spaced relation about the periphery of said open end, and a tubular end member open at both ends and slidable axially on the cylindrical member from a retracted position for inserting and packing tobacco within the open end of the cylindrical member without interference by said end member to a position projecting forwardly of said open end to receive the packed tobacco therein upon manipulation of the stem in said cylindrical member, said tubular end member being provided intermediate said ends with an amiular series of openings conforming in shape with a plane geometrical figure having greater length than width and adapted for slidably receiving the lugs and supplying air to the tobacco, the long sides of said openings being sufficiently close to each other to define narrow bars substantially parallel with the longitudinal axis of the tubular member and slidable between the lugs, and the opposite ends of the openings defining sections of annular walls alternately engaged by the lugs when said tubular end member is moved to its respective positions.
2. In a smoking device as described in claim 1, wherein the outer open end of the tubular end member is provided with inwardly projecting means to be engaged by the tobacco when the packed tobacco is pushed into the tubular end member and to move said end member to said projected position upon manipulation of the stem.
3. In a smoking device as described in claim 1, wherein the outer open end of the tubular end member is provided with an annular series of inwardly extending lugs adapted to be engaged by the tobacco when the packed tobacco is pushed into said tubular end member and to move said tubular end member to said projected position upon manipulation of the stem.
4. In a smoking device of the type comprising a cylindrical tobacco chamber, a stem at one end of the chamber and adapted to telescope in the tobacco chamber and a mouthpiece carried by the stem, wherein all the parts are in axial alignment and in interconnected relation, said tobacco chamber including a cylindrical member completely open at the end opposite said stem and having outwardly extending means forming a stop circumferentially of said open end, and a tubular end member open at both ends and slidable axially on the cylinder member from a retracted position for inserting and packing tobacco within the open end of the cylindrical member without interference by said end member to a position projecting forwardly from said open end to receive the packed tobacco therein upon manipulation of the stem in said cylindrical member, said tubular end member being provided intermediate said ends with an annular series of openings conforming in shape with a plane geometrical figure having greater length than width and adapted for supplying air to the tobacco, the long sides of said openings being suficiently ciose to each other to define narrow bars substantially parallel with the longitudinal axis of the tubular member, the opposite ends of the tubular member having portions adapted for alternate engagement with said stop means when the tubular end member is moved to its respective positions.
5. In a smoking device as described in claim l wherein the outer end of the tubular member is provided with an inwardly extending annular flange adapted to be engaged by the tobacco when the packed tobacco is pushed into said tubular end member and to move said tubular end member to said projected position upon manipulation of the stem.
