SMOKING 'TUBE Filed March 2, 1958 a. o r l?? enla ,4,

Patented June 13, 1939 UNITED STATES PATENT oFFlcEf 13 Claims.

This invention relates to improvements in smoking tubes of the type described in my Patents #2,099,925 and #2,099,926 issued November 23, 1937, and Patent No. 2,119,198 issued May 3l,

1938, and one of the objects ofthe present invention is to improve and simplify the construction ofsuch devices.

A further object is to provide an improved device of this character in which the tobacco may be readily yplaced into vthe tobacco chamber from either end thereof without necessitating the removal or separation therefrom of any great number of parts.

A further object is to provide in a device of this character improved means whereby air currents may be circulated within theV wall of and about the tobacco holding chamber to prevent the device from becoming heated to any greatY extent.

Tothe 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 numeral I5 designates a tubular member of any desired size and configuration and constructed of any suitable material, the member being open at both ends. Within the wall of the member I5 is arranged an air circulation space |6 one end of which communicates with openings I1 that extend through periphery of the member. The inner Wall I8 of the air space terminates short of the extremity of the member I5 as at I9, to form a circumferential shoulder, and the inner face of the outer wall above said shoul' der I9 may be provided with screw threads 2U.

The tubular member I5 constitutes the body portion of the tube andthe outer end thereof is closed by a unit which consists'of an end member provided with v'a wall 2| having apertures 22 therethrough, andfprojecting below the lower face of the wall is' a tubular extension 23. Another tubular extension 24 also projects below the lower face of the wall 2| and terminates short of the extension 23, the periphery of the extension 24 being provided with threads 25. The extension 24 is spaced from the extension 23 to provide a space `26 which space, when'the end member is placed inposition on the end of the tube I5 and the threads 25 engage `the threads 20, with the endV wall 2| projecting beyond the extension 24 so as to abut the end of the tubular memberv I5, willr register with the space I6 in the wall of the tubular member so that the air circulating in the space I6 will also circulate in the space 26.

The openings 22 in the end wall 2| are preferably disposed within the tubular extension 23.

'I'he end wall 2| is also provided with an opening 21 therethrough and through which opening 21a stem 28 on an abutment 29 passes.

The abutment member 29 is of a diameter to substantially ll the space within the extension 23 and is provided with a circumferential groove 30 on its upper face having openings 3| in theA bottom of the groove which pass through the abutment member. f

The end Wall 2| is provided with projections 32 within the extension 23, which pro-ject into the groove 30, for the purpose of maintaining the groove 3|) free of foreign matter, when the abutment member 29 is rotated or oscillated in a manner to be described.

A cap member 33` rests against the outer face of the end wall 2| and this cap member may be of any desired size and configuration, preferably being channeled out as. at 34 to its outer face providing a central projection 35 and which projection is adapted to receive a screw 36 that passes through the abutment member 29, the extension 28, and into the cap member.

The extension 28 on the abutment member is preferably bifurcated, as shown in Figure 7, and a projection 31 on the cap member extends into the bifurcation so as to cause the cap member 33 and the abutment 29 to rotate in unison when the cap member is rotated with respect to the tube or body portion l5. The extension 28 is of such a length that the cap member 33 and the abutment 29 will not bind the end wall 2|, which would interfere with the free rotation of the cap member. Y

The lower face of the cap member 33 is provided with a groove 38 which communicates with the opening 22 through the end wall 2| and projections 39 on the adjacent face of the end wall 2| extend into and operate within the groove 38 to keep the groove clean. The base ofthe cap member is also provided with openings 4I] therethrough which register with the groove 38.

Additional openings 4| are provided in the cap member 33 which register with openings 42 pre1'- erably in the form of extended slots in the end Wall 2| so as to form a communication between the openings 4| in the cap member 33 and the air space |6 in the body member |5.

The openings 42 are preferably in the form of slots of substantial length so that when the cap member 33 is rotated the outlet end of the air chamber I6 will always be open no matter to what extent the cap member has been rotated.

Thus it will be seen that the outer end of the tubular member |5 will be closed by a unit, the unit comprising the end Wallv 2| and its associated parts together with the abutment member l, 29 and the cap member 33, and that these parts are all secured in position by the engagement of the

threads

25 and 29 respectively on the extension 24 of the end member and the end of the tubular member, the end of the extension member 23 on the end wall abutting the shoulder |9 on the Wall |8.

In order to properly position the parts of the unit so as to open or close the openings or pas-' sages 22 through the end wall, there may be provided any suitable number of spring controlled elements 43 supported by the cap member and projectable beyond the lower face thereof within the periphery of the cap member. These elements 43 are preferably in the form of balls and are adapted to be yieldably seated in the slots or recesses 44 provided for that purpose.

The slots 44 preferably open through the periphery of the end wall 2| and notchesV 45 are provided in the proximate face of the cap member 33 and these notches 44-45 serve as indicating means whereby the user may, by the use of his fingernail determine the proper positioning of the openings in the cap member, Without looking at the device by reason of the fact that the fingernail will enter the slots or notches when they are in register. v

The central portion of the tubular member |5 constitutes a tobacco chamber 46 in which the tobacco 41 is arranged and one end of the tobacco. chamber is open. The other end of the tobacco chamber |5 is closed by a stemV 48 having a threaded portion 49 in one end thereof which engages with threads 5U. 'I'he upper or inner portion of the opening is preferably tapered or beveled as at 5| and against which portion 5| the beveled portion 52 of a bearing member 53 rests. This member 53 extends across and forms a closure for the tobacco chamber and is provided with any number of desired openings 54 therethrough.

The stem 48 is provided with a chamber 55 opening through the end thereof and depending from the member 53 are prongs or ngers 56 which are preferably resilient to snugly iit over the inner wall 51 of the chamber 55 in the stem so that when the stem 48 is detached from the body l5 the member 53 will remain in position with respect to the stem. Subsequently the member 53 can be detached from the stem.

A filter 58 of any suitable material is provided in the chamber 55.

A follower 59 is arranged in the tobacco chamber and is provided with a stem 60 preferably provided with an enlarged portion 6| that moves in a channel space 62 in the stem that is encompassed bythe wall 51. The stem 60 passes loosely through an opening 63 in the bearing member 53. A spring 64 within the stem 48 tends normally to urge the follower 59 toward the abutment member 29.

The stem is also provided with openings 65 which communicate with the chamber 55.

Thus it will be seen that when the tobacco is lighted at the cap end of the device the smoke will be `drawn through the tobacco chamber, thence through the openings 54 in the member 53 into the chamber 55 cn the outside of the filter 58. From thence it will be drawn through the filter and the openings 65 in the stem. 'Ihe spring 64 operating on the follower 59 always urges the tobacco forwardly toward the abutment.

At the top of the openings 65 and adjacent the bottom of the chamber 55 is provided a groove 55A so that the ends of the fin-gers 56 will not cut off the flow of the smoke through the passages 65 but the smoke will have a free circulation around the groove.

The ashes may be removed by simply rotating the cap with respect to the body |5 and this in turn will rotate the abutment 29. The air spaceA 6 provides a means for maintaining the device from excessive heating as the air will flow into the openings I1, thence into the passage I6 encompassing the tobacco chamber and then through the cap member.

While the preferred forms of the invention have been herein shown and described, it is to be understood that various changes may be made in the details of construction, and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this invention.
