SMOKING DEVICE Filed Feb. 14, 1945 INVENTO eayle /l//Pe e/ BY MVM-.4u
Patented Mar. 27, 1951 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to a device for smoking tobacco in loose form and ,has for its principal object to provide a device of this character that is more sanitary and pleasant to smoke in that the tobacco receptacle and smoke passages are cleared of ashes and accumulated matter prior to each loading of the device with tobacco.
Other objects of the invention are to provide a smoking device that simulates and smokes in the manner of a cigar or cigarette; to provide a smoking device that is of small, compact construction and collapsible to facilitate carrying thereof in a pocket or handbag of the user; to provide a smoking device which may be placed in the pocket while containing burning tobacco without causing a fire hazard or disagreeable odor; to provide a smokingk device that is selfextinguishing when not in use; to provide a smoking device with a means for preventing discharge of the ashes when using loose tobacco; to provide the ash retaining means with a cleaning device for removing accumulations from the smoke passages; and to provide a smoking device adjustable for containing various amounts Y of tobacco.
In accomplishing these and other objects of the invention hereinafter described, I have provided improved structure, the preferred form of which is illustrated in the accompanying drawing vvherein:v
Fig. l is a perspective vievv of a-smoking device embodying the features of the present invention.
Fig. 2 is a longitudinal sectional view through the device and showing the tobacco receptacle loaded with loose tobacco.
Fig. 3 is a View of the stem end of the tobacco receptacle.
Fig. 4 is a perspective vievv of a smoking device with the ash retainer grid and cleaning rod removed therefrom to better illustrate the construction thereof.
Fig. 5 is a perspective view of the bit and plunger members of the smoking device shown in disassembled spaced relation.
Referring more in detail to the drawings:
I designates a smoking device constructed in accordance with the present invention and Which includes a substantially elongated receptacle 2. The member 2 may be formed of any suitable material and has a cylindrical Wall 3 opened at one end to provide a charge opening 4 and the opposite end has an integral tapering portion 5 to provide an inner tapering seat Ii encircling an opening I for passing a stem 8 that telescopes Within the receptacle 2 for a purpose later described. The stem 3 includes a cylindrical duct portion S having an axial bore forming a smoke passageway Il! therethrough. One end of the stem carries a head or plunger II having a conical neck portion I2 substantially conforming to the taper of the seat 6 to form a substantially airtight seal therebetween when the parts are extended as Shown in Fig. 2. The head II terminates in a cylindrical piston-like portion I3 which substantiallyl conforms in diameter to the inner diameter of the receptacle so that the stem is closely guided therein and the forward annular edge I4 scrapes the inner Wall of the receptacle to clear it of ash and other accumulated matter vvhen burned tobacco is to be ejected from the receptacle. The opposite end of the stem is internally threaded as at I5 to receive the threaded nipple Ii of a bit I'I. The bit Il includes an annular base portion I3 of slightly larger diameter than the outer diameter of the stem so to form abutment against Which the end I9 of the receptacle is adapted to engage upon telescoping of the members as shown in Fig. 4. 'Ihe bit il otherwise conforms in shape to a conven tional bit such as used on a pipe or cigarette holder.
In order to retain the tobacco and ashes Within the receptacle and prevent spilling thereof, the open end of the receptacle is preferably provided With a cap 2li having a disk portion ZI provided With a plurality of perforations 22 through Which the air is drawn into the receptacle for promoting burning of the tobacco therein. The disk portion has a series of laterally extencing fingers 23 adapted to engage over the outer face of the receptacle and which terminates in outwardly eX- tending lips 24 which provide supports for the device when placed upon a table or the like to prevent scorching when burning tobacco is re tained in the receptacle.
In order to provide means for cleaning the smoke passageway IU, the cap 2li carries a rod 25 of wire-like and preferably flexible character and which is projected through tobacco in the receptacle and into the smoke passageway I0. If desired, the rod may be provided on the free end thereof with a series of barbs 26 to facilitate cleaning of the smoke passageway and removal of any tobacco that may tend to clog the inlet thereof. The rod 25 is of such a length that when the stem is telescoped Within the receptacle the free end thereof will not project from the opening in the bit Il. Therefore, the rod 25 is shorter than the total length of the device when extended; however, the entire length of the stem may be cleared With the aid of the rod by removing the rod from the receptacle and inserting it through the smoke passageway of the bit.
The periphery of the opening i is provided with a plurality of notches 2l extending from the tapered portion and through which any tobacco or other matter trapped between the plunger and the end of the receptacle is discharged upon reciprocation and rotation of the stem. The forward end of the head I I may have a tapered recess 28 formed therein.
In using the device for smoking loose tobacco, the cap 20 is removed from the open end of the receptacle and the rod is completely withdrawn.
The stem is extended from the opposite end oi' the receptacle 2 to seat the conical neck portion l2' thereof against the tapered face 6. The receptacle is then filled with tobacco after which the rod and cap are re-applied by pushing the rod through the tobacco and seating the resilient fingers 23 thereof about the periphery of the receptacle. The device is smoked in the manner of a cigar or a cigarette contained in an ordinary holder. When smoking, the device simulates a customary cigar or cigarette smoked in a holder. When smoked, the air is drawn through the openings 22 in the cap 28 to maintain burning of the tobacco.
When smoking is finished and it is desired to discharge the ashes, the cap 20 is removed and the rod may be completely withdrawn after which the stem 8 is pushed within the receptacle to cause the plunger head thereon to discharge the ash through the open end of the receptacle. Complete removal of the rod and re-insertion thereof in the smoke passageway I of the stem helps to maintain the passageway in clean and sweet condition. When the rod 25 is formed of flexible material, the rod may be pressed into scraping contact with the inner face of the plunger and stein, using the cap as a handle. Reciprocation and rotary movement of the rod in the smoke passageway I0 causes the barbs 26 to catch and loosen any accumulations therefrom.
As above pointed out, the rod will not extend the full length of the projected stem; however, the rod may be removed from the open end 4 of the receptacle and re-inserted through the smoke passageway of the bit i1 to reach the parts thereof.
It is obvious that when the device is being smoked the saliva flows through the bore of the stem and into the tobacco contained within the receptacle so that the stem remains comparatively free of such accumulations and that accumulations in the receptacle are readily removed upon discharge of the burned tobacco after each use of the device; consequently, the saliva and tobacco contained thereby is not accumulative from one smoke to the next. Thus, the device is` From the foregoing it is obvious that I have provided a smoking device that is adapted for smoking loose tobacco, and which may be cleaned after each use thereof incidental to the discharge of ashes and accumulation therefrom.A
What I claim and desire to secure by Letters Patent is:
1. A smoking device including a stem, a bit on the stem, a substantially elongated receptacle having one end slidably mounted coaxially on the stem and having a tobacco charging opening at the opposite end, a plunger on the stem movable in the receptacle for ejecting ashes through. the charging opening, an apertured cap removably closing the charging opening, and a rod carried by the cap and projecting axially through the receptacle and into the stem.
2. A smoking device including a tobacco receptacle having a cylindrical bore opening from one end and terminating at the other in an annu-- lar tapering seat, a stem having a smoke passageway connected with the bore of the receptacle, av plunger head on the stem having a tapering portion engaging in said tapering seat within thereceptaole, said plunger head having a tapering. recess in communication with the smoke passageway of the stem, an apertured member removably closing the open end of the receptacle, and a flexible rod on said member extending through the receptacle and tapering recess into the smoke passageway of the stem.
