SMOKING TUBE Filed May 21, 1937- 60 Q7 Off 696] 6 Q9 li n Il' mllllllll Patented May 31, 1938 UNITED STATES PATENT oFFlcNE 11 Claims.

This invention relates to improvements in smoking tubes of the type shown and described in my applications Serial Number 20,653 filed May 9, 1935 and Serial Number 83,239 led June 3, 1936, and one of the objects of the present invention is to improve the construction of such devices. Y

It has been found that in devices of this character, by reason of the heat generated in the chamber in which the tobacco is consumed, the device becomes heated to such an extent that it is uncomfortable to handle the same. It is therefore another object of the present invention to provide improved means for insulating the smoking or tobacco chamber, ther-eby reducing to a minimum the heating of the wall of such chamber.

A further object is to reduce the number of parts of the device, thereby not only reducing the weight of the same, but also simplifying the construction thereof.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention, and in which Figure 1 is a longitudinal sectional view of a device of this character constructed in accordance with the principles of this invention.

Referring more particularly to the drawing, the smoking tube consists essentially of a body member I5 which is hollow and is constructed of any desired or suitable material and may be of any desired size and configuration. One end of the body member is provided with a portion I5 of a bayonet joint element which is adapted to re ceive the end I1 of a stem I8. The end Il of this stem is shaped to form the other element of a bayonet joint, so as to separably lock the body and stem members together. The extremity I9 of the body member contacts a circumferential shoulder 29 on the stem member.

The numeral 2| designates a combined liner and end member which may be constructed of any suitable material and is hollow and provided with a partition 22 extending thereacross and in proximity to one end thereof.

The partition 22 is provided with any suitable number of holes or openings 23 passing therethrough. The outer end of the member 2| may be flanged as at 24 and a circumferential groove 25 is provided in the member and opens through the periphery thereof in proximity to the extremity of the member.

The member 2| is shaped to provide a circumferential should-er 26, and the body of the member 2| is of an external diameter slightly less than the internal diameter of the body member I5.

This member 2| is inserted into the open end of the body member I5 so that the circumferential ,y shoulder 26 will project over and will be in close proximity to the extremity 2l of the body member I5. Y

Arranged in the space between the periphery of the member 2| and the inner face of the body member I5 is insulating material 28 of any suitable material. This insulating material is preferably in the form of a tubular member, as shown in Figure 11, and is provided with a ycircumferential flange or collar 29, which latter, when the insulating material is in position, will project into the space between the shoulder 25 of the member 2| and the extremity 2l of the body member I5.

If desired, lugs or projections 30 may extend from the extremity 2'! of the body member I5 to impale the flange 29 of the insulating material 28, and contact the shoulder 26 of the member 2|, to hold the latter against rotation with respect to the body member when the parts are being fastened together.

The body portion of the member 2| is substantially co-extensive with the body m-ember l5 and in this body member l5 adjacent the point of connection of the body member l5 with the stem i8, is provided a circumferential shoulder 3|.

The body portion of the member 2| is of ductile material so that when the parts l5, 2| and 28 are assembled, the extremity of the body portion 2|, which is in proximity to the shoulder 3|, is flanged or deflected over the shoulder 3|, and with it the adjacent extremity of the insulating material 28 will be anged over the shoulder 3| as at 32.

Within the stem I8 is a chamber or recess 33 which terminates short of the free end of the stem but opens through the other end. rThe nul meral 34 designates a bushing or bearing member having a circumferential ange or head of a diameter greater than the diameter of the bearing member 34. This flange or head 35 engages and rests upon a raised portion at the end of the stern and which raised portion is of a diameter considerably less than the diameter of the adjacent portion of the body member l5, so as to form a space beneath the flange or head 35 for receiving a filter 31 which encompasses the raised portion., This filter 31 may be of any suitablematerial and is of a diameter substantially co-extensive with the diameter of the flangeor head 35.

It will be manifest that the bushing or bearing 34 being screwed into the end of the stem will be held in position and pressure will be relieved from the lter 31, yet the latter will be maintained in position. This filter 31 extends over one or more passages 38 in the stem that open through the stem beneath the filter and also open through the outer extremity of the stem. Within the chamber or recess 33 is arranged a plunger 39 which substantially fills the chamber, and connected thereto is a rod 4U of a diameter considerably less than the diameter of the chamber. This rod 48 projects through the bushing or bearing member 34 and is connected to a follower 4| which is of a size to t within the tobacco chamber which is formed by the member 2|.

The peripheral edge 42 of the follower may be reduced to form a cutting edge and any suitable number of slots or openings 43 may be provided through the follower@ At the diametric center of the follower there may be provided a raised or convexed portion 44, for a purpose to be set forth` This follower 4| is normally urged forwardly in the tobacco chamber preferably by means of a spring 45 disposed beneath the plunger 39 and the end wall of the chamber 33.

Arranged within the tobacco chamber formed by the member 2| and at the outer end thereof is an abutment member 46 provided with a stem 41 that is rotatably mounted in a bearing 48 in a cap or end member 49. This stem 41 is provided with a portion 50 which is angular in crosssection and also with a circumferential groove or recess 5| adjacent the angular portion 50.

A spring split washer 52 is provided, which encompasses the stem 41 and enters the recess 5|. The washer 52 is of a width to extend across an opening 53 in the partition 22` of the liner and Aend member and through which opening 53 the stem 41 passes to substantially. fill the opening.

The abutment member is provided at its cen- ',tral portion with a convexed surface 54 projecting into the tobacco chamber and is also provided with openings 55 which register with the openings 23 of the member 2| as well as the openings 6| in the member 49.

The abutment member is placed in position so that its outer face is disposed in close proximity to the inner face of the partition 22 and is provided with a circumferential groove 56 through the bottom of which groove the spaced slots or openings 55 open.

Projections 51 are provided on the inner face of the partition 22 which enter and move within the groove 56 so as to prevent accumulation of ashes or foreign matter in the groove which would impair the circulation of smoke or air through the openings 55. Similar projections 58 are provided on the other side of the partition 22 and these projections 58 enter and move in a groove 59 in the lower face of a portion of the cap member 49.

This cap member is provided with an open end 6l] and through the bottom of this open portion are arranged openings 6|. The projections 58 are of such a diameter that when they stand in alinement with the openings 6|, there will be a free air or smoke circulating space around the projections 58 and through the openings 6|.

The cap member 49 is also provided with a recess 62 which opens through the face that is invproximity to the end of the body member I5 and the wall'of this recess is provided with a circumferential groove 63.

The end member 2| above the shoulder 26 is provided with vertical slots 64 which extend through the shoulder 26 and have communication with the groove 25. Two of these slots are preferably provided, one opposite the other, and portions of the'walls of the slots intermediate their extremities are enlarged or cut away as at 65.

A locking spring 66 is provided which'is preferably of the semi-circular form, the extremities thereof being deflected as at 61 to form spaced parallel portions, and mounted upon these spaced lparallel portions 61 are balls or spheres 68.'

The body portion of the member 66 is adapted to be seated in the groove 25 in the end member 2|, as shown more clearly inFigure'10,`while the spaced vertical or parallel portions 61 are 'seated in theslots 64.' The balls or spheres 68 are freely movable upon the portions 61 of the member 66 and enter the enlarged or cut away portion 65 of the slots64.

When thisy member 66 is in position, the balls or spheres 68 will bepartially'seate'd. in the end memberZl and partially seated in the cut away portion 65 of the slots 64 in the end member 2|, and will also be partially seated in the groove 63 in the c'ap member 49 to lock these parts together. Y

The bottom wallof the slots 64 is cut away as at 69 beneath Vthe balls 68 so that when it is Vdesired to remove the cap 49 from the end member, which may be done by applying force to the cap member while the end member is held, and by exerting said force in a direction lengthwise of the axis of the cap member, the balls 68 by reason of the resiliency of the portions 61 of the spring member 66, will be forced into the cut away positions, but when the cap member is replaced the balls 68 will be temporarily depressed back into the cut away portion 69, until the cap is tion of the tobacco.

seated, after which the balls will spring out and enter` the groove 63.

The tobacco 'l0 is arranged within the tobacco chamber either loosely or in a carton or wrapper 1| and is placed therein by separating the stem and bodymembers |8| 5. The b-ayonet joint connection between these parts will permit such separation.

When the tobacco is placed within the chamber the stem and body members are then again attached. The spring 45 will force the follower 4| against the end of the supply of tobacco which will in turn be forced against the abutment member 45.

As the tobacco is consumed the abutment member 45 may be rotated'by grasping the body of the device in one hand and rotating the cap member 49 with respect to the body member. The cap member may be provided with a fluted or serrated periphery l2 provided for that purpose.

By reason of the shape of the abutment member 46 and the follower 4l, and particularly the convexed portions 44 and 54, the tobacco will be forced outwardly against the walls of the tobacco chamber, thereby resulting in a better consump- The ashes are removed by rotating the cap member. As the abutment rotates, the ashes at the lighted end of the tobacco will pass through the openings 55 in the abutment member 46 as well as the openings 23 in the partition 22, and thence through the openings 6I in the cap member 49.

By reason of the insulation 28 the bodymember I5 will be kept comparatively cool and the temperature thereof will not rise to a point where the device will be uncomfortable to handle.

In the use of the device the smoke is drawn from the tobacco chamber through the openings 43 in the follower 4l into the space between the stem and body members and below the follower 4I. From there it will be drawn through the filter 31 and thence through the openings 38 in the stem member.

The projections 58 and 51 are of diameters less than the diameters of the openings adjacent which they stand so that no matter what position the projections may assume with relation to the respective openings, the circulation of air through the openings will not be interrupted or cut off.
