SMOKING TUBE Patented Nov. 23, 1937 UNlTED STATES PATENT OFFICE 11 Claims.

This invention relates to improvements in smoking tubes of the type shown and described in my application, Serial Number 20,653, led May 9, 1935, and one of the objects of the invention is to improve in certain respects,the structure and arrangement oi the parts shown therein, and to provide improved means for preventing moisture or saliva from contacting the tobacco,` and to provide means within the smoking tube for catching and conning the saliva.

A further object is to provide an improved device of this character in which the tobacco may be inserted in a loose condition or in the form of a cigarette or cartridge, and improved means for automatically advancing the tobacco to the lighted end of the device as the tobacco is consuined.

A further object is to provide an improved device of this character which is of a sectional construction, comprising parts detachably secured together, whereby the insertion of the smoking material may be readily accomplished, and whereby the parts of the device may be readily separated to facilitate cleaning 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 drawings illustrating this invention, and in which Figure l is a longitudinal, sectional View of an improved device of this character constructed in accordance with the principles of this invention.

Referring more particularly to the drawings, the numeral 2l) designates generally a body portion or member, which may be constructed of any suitable material and of any desired size and configuration. The ends of the body are recessed at 2l-22 to form a dividing partition 23 having a central opening therethrough, and projecting axially from one end of the body member is a tubular member `Zll of any desired length and diameter and which is provided with a closed bottom Z5. The tubular member 24 may be formed integral with the partition 23 or may be formed separately and. attached thereto, and has communication with the central opening through the partition 23. This opening is preferably of a diameter somewhat larger than the diameter of the tubular member 24 and the wall of the opening is provided with a threaded recess 26, for a purpose to be later described.

The recess 2l is provided with screw threads 21, while the wall of the recess 22 is preferably smooth.

The partition 23 may be provided on one face with a groove 28 communicating with the recess 22, and openings 29, any number of which may be provided, extend through the bottom of the groove 28 to form communications between the groove 28 and the recess 2|.

The numeral 3U designates a hollow end member which is provided with a body portion having a reduced end 3| having external screw threads 32. The other end of the member 30 is closed as at 34 and has a central opening 35 there` through, and openings 36 are provided in the end 34 to encompass the opening 35. The end member 3@ may be of any desired and suitable length.

Extending across the openings 36 and projecting respectively beyond the opposite faces of the end wall 34 are Scrapers 31-38, and these scrapers are of a' thickness considerably less than the diameter of the openings 36 so as not to obstruct the openings to any great extent.

The end member 30 is attached to the body member 2l) by causing the threads 32 thereon to engage the threads 21 in the wall of the recess 2i, and when assembled, a shoulder 39 formed by the reduced end 3l of the member 30 will abut the end of the body portion 2U. The external contour of the member 30 is shaped to conform to the contour of the body 29, and if desired portions of the end member 3B may be removed as at 40,

for the sake of ornamentation and also for the purpose of imparting lightness to the structure.

The numeral 4I designates a stem or mouth piece which may be of any desired size and configuration and is provided with` a reduced extremity 42 having a smooth periphery providing a shoulder 43. This extremity 42 is adapted to t in the smooth recess 22 of the body member 29 so that the two will be frictionally bound together and so that the shoulder 43 will abut the end of the body member 29. Y

Within the stem 4| are passages 44, any number of'which may be provided. One end of each passage opens through the extremity 45 of the stem and the other end of each passage has communication with VYa chamber 46 in the stern. A portion of the stem within the chamber 46 projectsabove the bottom of the chamber and is of an external diameter considerably less than the internal diameter of the chamber so as to form a pocket 48 to prevent saliva from running back th-roughrthe openings or passages 44.

The portion 41 terminates short of the top of thefchamber and a'closure 49 is provided for the chamber. This closure is provided with a reduced portion 50 forming a shoulder 5l and a tubular extension 52 which is of'a diameter considerably less than the diameter of the closure. The reducedportion renters the chamber 45 and the closure is frictionally held in position with the shoulder 5l abutting the end of the stem or mouth piece. 4I. The periphery of the closure 49Y is preferably beveled or shaped as at 53 to form a finger engaging portion to facilitate the removal of the closure when desired, and a recess or pocket 54 is provided Ywhich opens through the top of the closure and communicates with an opening 55 which extends through the portion 52 of the closure.

I The reduced end 42 of the stem 4I is of such a length that when the shoulder 43 abuts the inner end of the body member 29, the inner extremity of the stem member will terminate short of the partitionr23ein the body member 20 to form a recess or chamber in which is arranged a filter 56, constructed of any suitable material and preferably in the `form of a disc, which substantially lls the space between the extremity of the stem member 4| and the proximate face rof the partition 23 of the body member 29. This lter will extend over the groove 28 in the partition 23, .as well as over the recess 54 in the closure member 50 at the end of the stem or mouth piece to the end of the stem is connected a head 5S hav- .ing any desired number of openings 69 therethrough, and the head '59 is of a diameter to substantially ll the chamber 6I in the end member 30. The periphery of the head 59 is preferably beveled as at 62 to form a substantially sharp edge 63 which contacts and moves along the wall of the chamber 6| in the end member 30. VA nut 64 encompasses the rod or stem 58 and is adapted to be threaded into and seated within the recess 26 in the partition 23 so as to form a guide for the stern 58 and to hold the same centrally positioned.

- Recesses 65 are provided in the upper face of the nut 64 by means of which the nut 64 may be readily removed or seated when desired, and in a manner to be set forth.

The head 59 is preferably provided with a hub 66'and pins 61 project below the end Of, the hub and are adapted to be seated within the recesses 65 in the nut 64 and to be removed therefrom. When seated in the recesses, it will be manifest that by placing the finger upon the head 59, when the end member 3Q is removed, and rotating the head in the proper direction, the nut 54 may be screwed out of its seat. Likewise, by depressing the head 59 and rotating the same in the opposite direction, the nut 64 will be seate-d.

A spring 68 is provided in the tubular member 24 between the closed end 25 thereof and the lower end of the plunger 5l, and the normal tendency of the spring 68 is to advance the plunger 5l to move the head 59 toward the closed end 34 of. the chamber 6| in the end member 39, for a purpose to be described.

The advancing movement of the head 53 and plunger 5'! under the stress of the spring 68 will be arrested by reason of the end of the plunger 51 contacting with the lower face of the nut 64.

The numeral 99 designates an abutment member which is provided with a stem l@ angular in cross sectionpreferably having two opposed flat sides, although the stem may be of any desired configuration in cross section. The stem l5 is formed by reducing a portion of opposite sides thereof to provide a shoulder 'li and a circumferential groove ,i2 is-provided in the stem.

Thisv abutment member is placed in position within the chamber 6I in the end member 30 through the open end thereof, so that the stem will pass through the opening 35 to such an eX- tent that the groove. I2 will be disposed beyond the outer surface of the end wall 34 of the chamber 6l of the end member 39, but in proximity thereto.

Openings '53 pass through the member 69, and any number may be provided and may be suitably arranged .so that Ythey may be moved into and out of alinement with the openings 36 in the end Wall V34 of the end member 30. In the upper face of the member 69 is an annular groove 14 with which the openings 'I3 communicate.

The numeral 'E5 designates a cap member which is hollow and is provided with a partition 'l5 intermediate the ends of the member. The portion of the cap below the partition 16 forms a recess orrchamber ll having a circumferential groove YI8 in the inner wall thereof and spaced from the ends of the chamber. Also provided in the wall of the chamber 'Il are any desired number of grooves 19 (see Figure 2) which intersect the groove 'i8 so as to form spaces for the reception of locking elements to be hereinafter described. The portion of the member 'I5 above the partition l5 forms a chamber 80, and the outer wall of this chamber may be cut away or recessed as at 8|, for the purposes of ornamentation and also for the purposes of imparting lightness to the structure.

A projection 82 extends beyond the partition l5 into the chamber 8i) and is preferably centraily located. This projection is hollow and communicates with the chamber 'Vl through the partition 16. One part of the hollow portion of the projection 82, such as at 83 (see Figure 2), is of a diameter considerably greater than the diameter of the portion 84 to form a shoulder 85 against which the shoulder 'H of the stem of the abutment member 69 rests, while the portion 84 in the projection 82 is angular in cross section to conform to the contour of and receive the angular portion 'I9 of the abutment member 69.

Openings 86 extend through the partition 16 to form communication between the chamber 86 and the recess or chamber 11, and any desired number of these openings may be provided. A groove 81 is provided in the lower face of the partition 16, and with which groove the openings 86 have communication. i

When the abutment member 69 is placed in position in the cap member 15 with the recess 12 above or beyond the wall of the end member 3U, but in close proximity thereto, a fastening device, such as a C shaped spring 88 is placed within the recess 12 so as to extend beyond the wall of the opening 35 and rests against the outer face of the wall 34 at the end of the end member 30. This will secure the abutment member 69 to the cap member 15 so that both will be rotatable with respect to the end member 30. When thus assembled, the end wall 34 rof the end member 39 will be disposed between the abutment 69 and the partition 16 in the cap member 15. The outer face of the end wall 34 will abut the lower face of the partition 15, and the upper face of the abutment 69 will contact the inner face of the end wall34.

Owing to the angularity of the portion 10 of the abutment 69 and the angularity of the recess 84 in the cap member 15, these two elements will be secured for simultaneous rotation with respect to the end wall 34 of the end member 30.

In this position the grooves 14 in the abutment member E9 will be in communication with the openings 36 through the end wall 34 of the member 39, when the parts assume a predetermined relative position so as to bring the openings 88, grooves 81, openings 36 in the end member 39, grooves or recesses 14 in the abutment member 69, and the openings 13 through said abutment member, in registration. However, when the cap member 15 is rotated with respect to the end member 39 the openings 86 in the cap member and the openings 13 in the abutment member will be moved out of registration with the openings 36 in the end wall 34 of the end member 39.

The cap member 15 is placed in position by inserting the end of the end member 30 into the chamber 11 in the cap member until the end 90 of the capmember abuts the peripheral shoulder 9| on the end member 30.

These parts when thus assembled are detachably secured together but for relative rotary movement. preferably by means of a semi-circular member 92 constructed of any suitable material and provided with depending parallel arms or portions 93 at the ends thereof.

The portion 92 of` this member is adapted to be seated in a recess 94 (see particularly Figure 17) in the periphery of the end member 30, while the arms or portions 93 are adapted to be seated in slots 95 which are arranged at right angles to and communicate with the groove o-r recess 94. Portions of the walls of the slots 95 are recessed as at 96 to form a cavity 91 and the bottom of the slots 95 is preferably concaved, as at 98.

The numeral 99 designates globular members, through which the arms or portions 93 of the member 92 loosely pass.

When the portion 92 is seated in the groove 94 and the portions 93 seated in the slots 95, the globular members 99 will be seated in the cavities 96. These members 99 are of a diameter that in the normal position of the portions 93 of the member 92, they will project for a suitable distance beyond the periphery of the end member 30, so that when the cap member 15 is placed upon the end of the end member 30, the inherent resiliency of the member 92--93 will cause portions of the globular members 99 to be seated in the recess or groove 18 in the wall of the chamber 11 of the cap member 15.

By reason of the concaved bottoms 98 of the slots 95, it will be manifest that while the cap member 15 is being placed upon the end member 36, the portions 93 of the member 92 will be flexed by reason of the globular members 99 contacting the wall of the chamber or recess 15, to permit such assembling, and as soon as the cap member is seated upon the end member 3U, and the groove 18 properly positioned with respect to the globular members 99, the latter will, through the resiliency of the elements 93 be forced into the groove 18 so that the cap member will be rotatably secured to the end member.

The resiliency of the members 93, however, is such that the parts will under normal conditions be locked together, but, under abnormal force the cap member may be removed from the end member 39 by moving or forming the same lengthwise and away from the end member 39. The recessed portions 96 of the walls of the slot 95 forming the cavities 91 also serve the purpose of preventing the globular members 99 from dropping out of position with respect to the members 93.

The intersections 19 (see Figure 2) of the groove 18 form seats or interruptions in the grooves 18 into which the globular members 99 are forced when the cap member has assumed a predetermined rotated position with respect to the end member 39 to lock the parts in this adjusted position.

When it is desired to light the contents of the chamber 6|, the cap member 15 with the abutment member 69 are rotated with respect to the end wall 34 of the chamber 6I of the end member 3l] so as to bring all of the openings in direct alinement, thereby enabling the contents of the chamber 6| to be ignited.

After the ignition, the cap member 15 may be rotated in the manner just described, so as to move the openings 86 and the openings 13 through the end member 10 out of direct register or alinement with the openings 36 in the end wall 34 of the end member 39, so that the air entering the combustion chamber 6| will flow through a tortuous passage. That is, through the openings 86 and grooves 81, thence through the openings 35 in the end wall 34 of the end member 39 and then through the openings in the abutment member.

In Figure 15 is shown another form of locking means for securing the cap member 15 rotatably to the end member 30, and in this modied form, the numeral |09 designates a C shaped body portion having arms or depending portions |9|, portions |82 of which latter are deflected to form projections to enter the groove 18 in lieu of the globular members 99.

The stem member 4| is provided with a recess |63 (see Figure 6) intermediate the grooves or passages 44, and a portion of the stem which passes through the chamber 66 is of an external diameter considerably less than the diameter of the chamberY 46 to form a tubular portion |94., the extremity |65 of the tubular portion projecting above the end of the portion 42 of the stem member, so that when the closure 99 for the chamber 46 is in position, the upper surface of the closure will be substantially flush with the extremity |95 of the tubular portion |04, (see particularly Figure 6), so as toY assist in supporting the lter 56 in position.

Either the entire opening 55 or portions thereofthrough the projecting portion 52 of the cap member 49 is or may be of a diameter slightly greater than the external diameter of the portion of the tubular extension |94 which passes therethrough so as to provideV a passageway |96 between the wall of the opening 55 and the periphery of the tubularextension |94, sorthat the air currents and the smoke which is drawn from the combustion chamber 6| through the openings 29 in the partition 23 of the body member, and through the filter 56 into the recess 54 in the cap member 49, will ilow into the saliva collecting chamber 46 through the opening |06. From the chamber 46 the smoke will be drawn through the stem member by means of the passages 44.

Obviously, the passage |66 may be a single passage or may be a plurality of passages, as shown more clearly in Figure 13.

The

Scrapers

31 and 39 are provided for the Vpurposes of respectively removing foreign matter from the

grooves

81 and 14 respectively in the partition16 of the cap member 15 and in one lface of the abutment member 69.

Obviously, the grooves and passages in the various parts may be of any desired width, length and "Y conguration.

The product |91 to be smoked may be either in the form of` loose tobacco, cigarette or cartridge, and if in the form of a cigarette or cartridge, is of a diameter to substantially ll the chamber 6| in the end member 30. To insert the same, the end member 39 with the cap member attached thereto is detached from the body member 23, and the cigarette, cartridge or tobacco is inserted into the chamber 6|, after which the end member 3|! is secured to the body member 23. When the product has been placed in the chamber 6| of the end member 30, the end member is secured to the body member and during such securing operation the end of the product, if a cigarette, Vor the end of the charge, will contact with the head 59, and the latter will be depressed against the stress of the spring 68. v

Inasmuch as the openings in the abutment 69, the partition 16 in the cap member 15, and the openings 3B in the end wall 34 of the end member 39 are placed in alinement, it will be manifest that by applying a lighted match the tobacco will be ignited through the registering openings.

During the smoking operation, the smoke will be drawn through these openings in the head. If the openings are in direct registration, there will be a direct draft through the openings, but if the cap member is rotated so as to move these openings out of direct but into indirect communication, the passage of the air being drawn into the chamber 6| will be in a tortuous passage.

During the smoking operation the smoke will be drawn through the filter 56, thereby causing a iltration of the smoke and the removal of a considerable portion of the nicotine. Y

The saliva will accumulate in the saliva collecting chamber 46 and the saliva will be prevented rom flowing through the passages 44 in the stem 4| by reason of the pocket formed by the projecting portions 41 extending into the chamber 46 and the lter 56 will prevent the saliva from running back into the combustion chamber to contact with the tobacco.

As the tobacco is consumed, the spring 68 will cause the headv 59 to force the unconsumed tobacco intolcontact with the abutment 69, and this operation will continue until the tobacco is consumed.

The advancing movement of the head 59 under the stress of the spring 68 will be interrupted by contact of the plunger 51 with the nut 64.

During the smoking operation, if it is desired to remove any ashes which may accumulate or form at the end of the tobacco adjacent the abutment'member 69, the latter may be rotated by rotating the cap member 15 with respect to the end member 30, and this will cause the ashes to pass through the registering openings to be discharged through the chamber 89 in the cap member 15.

With this improved construction it will be manifest that a simple and practical device is provided, and a sanitary construction will result, it being possible to separate all -of the parts if desired, for the purpose of cleaning, and if desired, the stem 4| may be removable in order to permit ofthe changing of the lter material 56.

While the preferred formsof 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.
