SMOKING PIPE.

Application filed March 26, 19.23. Serial No. 627,556.

To all whom it may concern.' Y

Be it known that I, GEORGE WV. CoNLEY, a citizen of the United States, residing at heatOn, in the county of Du Page and State of Illinois, have invented a certain new and usefulA Improvement in Smoking Pipes, of lwhich the following is a'full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements 1n smoking pipes. c

One obj ect of the invention is to provide Iasmoking pipe of simple construction, so arranged that a cool, dry smoke is assured, wherein caking of the material at the bottom ofthe bowl is prevented, and the accumulation of nicotine and moisture is trapped within the stem to prevent the same from reaching the users mouth. y

Y. Another object of ,ther invention is to provide a pipeof the character indicated, wherein the stem and-bowl have associated therewith a draft ltube so arranged that suction will be created at the center of the bowl as well as at the entrance to the stem. .A Y

A lstill further object of the invention is rto provide a pipe `of the character indicated whereintlie'stemV is provided with a lining and in which vboth the lining of the stem, and the draft tube are formed of material which is imperviousto moisture, preferably metal, `whereby the parts are prevented from absorbing nicotine. o A more specific object of ythe invention is to provide a smokingv pipe constructed of separate'parts, which may be easily and quickly disa'ssociated to facilitate the cleaning of thel pipe, and wherein a draft tube having a baffle plate therein is provided and the draft tube is so arranged asto extend linto thebowl an appreciable distance.

Other objects and advantages of the invventionwwill more clearly appear from the description' and claims hereinafter followi In the; drawing forming a part of 'this specification, Fig. 1 isa vertical, flongitudinal, sectional view through a smoking pipe illustrating my improvements in connection therewith. Figt 2 is a transverse, vertical, sectional view on an enlarged scale, corresponding substantially to the line 2-2 of Fig. 1, and Fig. 3 isa vertical, longitudinal, sectional view similarjto Fig. 1 of the partson an enlarged scale. Y

In said drawings, A indicates the bowl of thek pipe, B they stem portion which is formed integral with the bowl, andl C the detachable mouth piece. l i' The stem B is provided with a longitudinally extending bore 10A communicating at one `end with the interior of the bowl A and adapted to receive the reduced portion 11 of the mouth piece C within ther other end thereof; the reduced portion 11 being adapted to lit the bore with sufficient tightness to hold they part-s normally inl assembled relation`and yet permitting the mouth piece to be forcibly detached' from the stem when desired. The bore 10 of the stem is provided with a tightlylitting tubular lining 12 which is impervious -to moisture, being preferably formed of metal. l

Y The mouth piece C has rigidly secured thereto a draft tube 13, vthe latter being driven into the slightly enlarged portion l14 of the bore 15 of the mouthpiece C,

and extends from the reduced end Aportion of the mouth piece throughl .the bore of the stem into the bowl A. A metal collar 33 .is secured to the` tube 13 near the outer end thereof, just inwardly of the end of the tubular vlining 12, the collar being spaced slightly from the lining. As clearlyshown inFig. 1, the draft tube 13 is arranged axially' of the'bore 10 ofthe stem B and in spaced relation to the inner v a portion of the bowl and stem, showing' Wall yof the tubular lining 12, thereby pro- Vviding an annular chamber 16.V Communication between the. rear endportion of the tube 13 and the bore 15 of the mouth piece visestablished through the open endl 17 of vthe tube. The opposite end 18 ofthe tube 13 is also open and establishescommunication between the interior of the bowl and v.the frontend portion of the tube. .Tlietube is provided with a plurality ofvperforations, preferably five, the saine being indicatedV by 19 to 23 inclusive. The perforations 19, 21 and 22 are located at the upper side of the tube and the perforations'20 and 23 are located at the lower side thereof.l As clearly shown in Figs. 1 and 3, the perfor- ations 19, 20, 22 and 23 are arranged in sets, the first set comprising the vertically alignedperfo rations 19 yand 20, the second set vcomprising the vertically aligned perforations 22 and 23. The perforations 19 and 20, formingvthe first set, are locatedA near the outer end 18 of the tube 13, beyond the collar 33 and communicate directly with the interior of the bowl A; the perforations 22 and 23 forming the Second set,l areV located near the point where the tube 13 enters the mouth' piece and communicate with the chamber 16; and the perforation 21 is located between the two sets of perforations and also communicates with the chamber 16 Intermediate the opening 21, and the set of openings 22 and 23, the draft tube 13 is provided with a transversely arranged partition or baille wall 25, cutting off communication between the front and the rear ends of the tube 13 and dividing the same into two compartments or chambers.

The suction created in smoking the pipe will cause a vacuum to be formed in the chamber 16, thereby drawing the smoke into said chamber through the space between the collar 33 and the lining tube 12 and through the tube 13, the smoke passing into the tube thru the outer open end 13 thereof and the diametrically'opposite perforations 19 and 20, and passing from the tube 13 to the chamber 16 through the perforation 21. The battle plate 25 prevents smoke from directly entering the rear end of the tube 13. The smoke passes from the chamber 16 into the rearend of the tube 13 through the perforations 22 and 23 and out through the bore 15 of the mouth piece. It will be evident that any nicotine or moisture collecting in the chamber 16 and in the tube in front of the baffle plate 25 will accumulate in the bottom of the chamber by flowing down the side walls of the chamber and draining off through the lower perforations 2O of the tube 13.

Any saliva entering the rear end of the tube 13 through the mouth piece C will pass out through the lower perforation 2li into the lower portion of the chamber 16. Should any nicotine or moisture pass into the rear end of the tube 13 through the perforation 23 the same will also pass out through the perforation 24:.

The passage of smoke from the bowl through the' outer end of the tube, into the chamber 16 and out through the rear end of the `tube 13 will have a cooling and drying tendency by reason of t-he provision of the front chamber of the tube formed by the baffle plate 25, and the chamber 16, in which the smoke may eddy and deposit its moisture.

It will be evident from the foregoing description that I have provided a pipe of exceedingly simple construction, the parts of which may be easily disassembled for cleaning and wherein the parts subject to direct contact with the smoke as it first passes out of the bowl, are constructed of impervious material, preferably metal, thereby preventing absorption of nicotine is merely illustrative andI contemplate all i changes and modifications that come within the scope of the claims appended hereto.

l claim: v

In a smoking pipe, the combination with a stem and mouth piece; of a Adraft tube communicating with said mouth piece, said tube being divided into separate comparments; a chamber surrounding said tube intermediate the ends thereof, said chamber communicating with said compartments and said bowl, and said compartments communieating respectively with said bowl and said mouth piece. l
