TOBACCO- PIP E.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed March 12, 1913. Serial No., 753,811.

To all whom it may concern:

Be it known that I, JOSEPH H. Born, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Tobacco-Pipes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This'invention relates to tobacco pipes, and has for its object to provide a pipe composed of detachable parts, so arranged and constructed as to thoroughly and reliably clean the pipe when the parts thereof are detached.

A further object is to provide a tobacco pipe having means in itself for thoroughly cleaning the smoke flue from a point directly under the bowl to the mouth piece when the stem is disengaged from the remainder of the pipe.

Another object is to provide a pipe in which the smoke is caused to travel a cir; cuitous route, thereby insuring a cool and purer smoke to the user.

In the accompanying drawings, Figure 1 represents a longitudinal sectional view of the pipe complete. Fig. 2 represents a bot tom plan thereof. Fig. 3 represents an enlarged sectional view through the bowl. Fig. i: represents a sectional view on the line it- 1 of Fig. 1, and, Fig. 5 represents a top plan view of a portion of the stem and sleeve.

Referring to the drawings, the numeral 1 indicates the bowl of the pipe, constructed of any desired form, and is preferably pro vided with an integral base 2, communicat ing with the interior of the bowl 1 by the passage 3. The hollow stem 4 is provided with a reduced sleeve 5 which is adapted for frictional engagement within the opening of the base 2, while on the opposite end of the stem 4 is threaded a mouth piece 6 which may be formed of any desired material such as rubber, amber or the like. The extreme end of the sleeve 5 is provided with a re cess 5. The bore through the base 4 is preferably larger than the bore in the ordinary pipe, so. as to snugly receive the shank 7 having one end fixed in the bowl 1 by means of the pin 8, which latter may be removable. The shank 7 is of the proper length so as to abut themout-h piece owith its free end when the parts of the pipe are assembled, as shown in Fig. 1. The shank 7 is provided with a spiral groove 9 extending throughout the entire length thereof from a point directly beneath the passage 3 to the mouth piece 6, and the pitch of said groove is gradually decreased from the free toward the fixed end thereof. A short bore 10 which is in registration with the bore of the mouth piece is formed from the free end of the shank 7 a distance inwardly through said shank and is connected with the spiral groove 9 by the passage 11. The passage 11 is preferably formed at or near the free end of the shank 7 in order that the bore 10 will serve as a trap to arrest the flow of saliva.

The bowl of the pipe is preferably const ructed of wood, and the stem 4 of hard rubber so as to provide a non-binding housing for the shank 7, which latter is preferably formcd from some light metal such as aluminum.

A semi-spherical lug 12 is formed at the extreme endof the sleeve 5 and is snugly engaged within the spiral groove 9 of the shank 7, so that when the shank 4 is separated from the bowl 1 the lug 12 will travel through the groove and effectively clean therefrom any accumulation of saliva or tobacco oil. As the lug 12 engages the threads at the extreme end of the shank 7 directly beneath the passage 3, it will be seen that the shank will be thoroughly cleaned throughout its entire length when the parts are separated.

What I claim is 1. A pipe comprising a bowl, a spirally grooved shank secured to said bowl, a hollow stem engaged over said shank, and means carried by said stem for engaging within the groove and adapted to travel outwardly therethrough when the stem and bowl are detached.

2. A pipe comprising a bowl, having a recessed base formed thereon, and a passage connecting the interior of the bowl and the recess in said base, a spirally grooved shaft having one end secured in said bowl at the inner end of said recess, a hollow stem removably engaged over said shaft and having a reduced end seated in said recess around said shaft, said stem having a recess therein affording communication between the passage in saidbowl and the groove in said shaft, and a lug on said stem engaging said groove and adapted to travel outwardly; I A

thereover when said stem is removable from said bowl.

3. Apipe comprising a bowl, having a recessed base formed thereon and a passage connecting the interior of the bowl and the I v inner end of said recess, a hollow stem removably engaged over said shaft and having a reduced end seat in said recess around said shaft, said stem having a recess therein affording a communication between the passage in said bowl and the groove in said shaft, means carried by said stem for, engaging the groove and adapted to travel therein when said stem is removed from said bowl, and a mouth piece secured at the outer end of said stem, said shaft having a 1ongitudinal bore closed at its-inner end and in alinement With the bore in said mouth piece, said shaft provided With a passage connecting said bore and the groove in said shaft near the outer end of saidvbore.

In testimony whereof have signed my name to this specification in the presence 25 witnesses.
