Application April 19, 1933, Serial No. 666,824

8 Claims.

This invention relates to new and useful improvements in a sanitary smoking stem for pipes.

The invention has for an object the construction of a stem as mentioned which is characterized by a novel arrangement of a hollow tube adapted to threadedly engage into a bushing mounted in the base portion of a hollow pipe stem and engaging into a substantially cup shaped member arranged with a projecting stem engaging into the mouth piece of the pipe in conjunction with an arrangement to allow the passage of the smoke.

Still further the invention contemplates the construction of a smoking stem for pipes substantially as described in the previous paragraph which has the function of producing cool and dry smoke.

Still further the invention contemplates the arrangement of forming the stem upon the cupshaped member with a slot extended in from the end which slot is adapted to produce a certain amount or" springiness to hold the cup-shaped member in place upon the mouth piece, and furthermore which slot is adapted to engage a flattened portion upon the tube to constitute a tool by which the tube may be screwed into and out of place.

Another one of the cbjects'of this invention is the arrangement of a slot upon the inner end of the pipe mouth piece adapted to coact with the slot in the stem of the cup shaped member so as to provide a passage for the smoke.

Another one of the objects of this invention is the provision of a means whereby the stem of the cup-shaped member may be mounted in various positions upon the mouth piece so as to determine the size of the passage for the smoke.

Still further the invention contemplates the construction of an article as mentioned which is simple and durable and which may he manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features or" the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a longitudinal vertical sectional view of a pipe provided with a smoking stem according to this invention.

Fig. 2 is a perspective view of the bushing, the tube and the cup shaped member shown in Fig. 1.

Fig. 3 is a transverse vertical sectional View taken on the line 33 of Fig. 1.

Fig. 4 is a perspective View of the inner end of the mouth piece of the pipe.

Fig. 5 is a fragmentary horizontal sectional view taken on the line 55 of Fig. 4.

Fig. 6 is a similar view to Fig. 1, and shows the insertion of the tube in the pipe stem.

The sanitary smoking stem for pipes is used in conjunction with a pipe having a bowl 10 formed with a hollow stem 11 connected with the bowl by a passage 12. A mouth piece 13 is formed with a reduced end 14 adapted to engage into the end of the hollow stem 11 and frictionally or in any other manner maintain its position. A bushing 15 is threadedly engaged into the base of the hollow stem 11. A tube 16 is threadedly engaged into the bushing and connects with the passage 12. The front end of the tube 16 is formed with flattened sides 17 for the purpose hereinafter described.

A cup-shaped member 18 engages over the tube 16 and has a rear stem 19 engaging into the inner end of the mouth piece 13. The rear stem 19 is formed with a slot 20 extended in from its end and adapted to align with small slots 21 extended in from the end of the reduced portion of the mouth piece 13. The slots 21 extend substantially half of the length of the reduced portion of the mouth piece as clearly shown in Fig. 4. It is pointed out that the smoke may travel from the interior of the hollow stem into the slots 21 through the edges upon the end of the reduced portion and then through the slot 20 in the stem 19 and then through the mouth piece 13.

A means is provided for holding the stem 19 in various longitudinal positions within the end oi the mouth piece so as to vary the size of the passage for the smoke. If the stem is in a position illustrated in Fig. 1 then the smoke may pass directly into the end of the slot 20 in addition to passing through the slots 21 and then into the slot 20. The base portion of the slot 20 is formed of substantially V-shape so that its area increases gradually and so better controls the size of the passage for the smoke as the stem is adjusted upon the mouth piece.

The means for holding the stem in various positions comprises a projection 24 upon the end of the stem, on one side thereof adapted to engage into a longitudinal groove 25 formed upon the inner wall of the stem 13. This groove is formed with several transverse branches 26 so that when the stem is engaged to certain posiare accessible to be readily cleaned.

tions it may be rotated to cause the projection 24 to engage into one of the branches 26 and so look the stem in the desired position. The branches 26 are so arranged that when the projection 24 is engaged into any one of them, then the slot 20 simultaneously aligns with the slots 21.

The slot 20 and the stem 19 has a still further function, namely that of a tool wherein the stem 19 may be engaged over the flattened side 1? of the tube 16, to rotate the tube manually so that it may be engaged into or removed from the bushing 15.

The operation of the device is as follows: When a smoker draws upon the mouth piece 13 the smoke will be drawn in through'the passage 12 and then through the tube 16 into the cupshaped member 18. The smoke then moves backwards to the edge of the cup-shaped member and around the outside of the cup-shaped member and through the slots 21, the slot 2c and the passage in the mouth piece. The path through which the smoke must go, serves to dry the smoke and produce a cool smoke.

It will be recognized that the juices from the tobacco cannot very readily be drawn through the mouth piece with the arrangement disclosed. Because of the exceptional path which the smoke must take it becomes cooled during its travel. The pipe may be cleaned by separating the mouth piece 13 from the sten removing the cup-shaped member 18, using the stem portion 19 as a tool to remove the tube 16 and then all the parts The stem 19 may be removed from its position in the mouth piece by first partially rotating it so as to cause the projection 24 to move out from the branch 26 and then the parts may be moved longitudinally, with the projection 24 passing through the groove 25.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
