GAUTRON 2,112,018 DEVICE FOR ELIMINATING NOXIOUS SUBSTANCES CONTAINED IN TOBACCO SMOKÉ Filed oct. 4, 1934 Ewä 41W? n Patented Mar. 22, 1938 2,112,018 UNITED STATES PATENT OFFICE 2,112,018 DEVICE FOR ELIMINATING NOXIOUS SUBSTANCES CONTAINED IN TOBAC' CO SMOKE Louis Georges Gautron, Geneva, Switzerland Application October 4, 1934, Serial No. 746,854 In Switzerland October 15, 1933 1 Claim. (Cl. 131-12) 'I'his invention relates to improvements in de with narrow slits I’ and 2’ on their extremities. vices for eliminating noxious substances con These slits permit smoke to pass in one direction, tain-ed in tobacco smoke. but prevent the ñow of matter in the opposite The accompanying drawing illustrates exam direction. 5 ples of construction of the invention. The smoke is compelled to pass to the interior 5 Figure 1 is a vertical sectional view of a tobacco pipe embodying the present invention. Fig. 2 is an elevational view of one of the cap shaped members of the present invention with 10 the slit closed. Fig. 3 is a View similar to Fig. 2 with the slit open. Fig. 4 is an end View of the cap-shaped member. As shown in the drawing, the pipe comprises a l5 bowl portion 6, a mouthpiece -I, and a connecting stem 5. , The bowl of the pipe is integral with a tube 6', connected to draw-tube or mouthpiece 'l for the smoke by means of tube or stem 5. NJ O A union I3 screwed into the mouthpiece 'I is forced into the tube 5 and a union I2 similarly connects the tubes 5 and 6'. The stem portion of the bowl is provided with a chamber in which is mounted a smoke-treating 25 unit. This unit comprises upper and lower tubu lar members I6 and I'I, respectively, joined to gether as illustrated. The lower member I'I has a recessed portion I 8 which is placed in register with the smoke duct I9 of the bowl. A nozzle I4 30 projects upwardly from. the recessed portion of mlember I1 into the chamber I0 of the upper member I6 and has a rubber cap-shaped member I fitted thereon. The lower portion of member I'l serves as a receptacle 9 for saliva and is provided with a drain plug II. A cage-like member is carried by the upper end of member I6 for receiving and retaining a wash er 4 ñlled with spongy material 3. Stem 5 has a tube I5 provided with a screw-threaded base 40 mounted thereon in axial alignment with the smoke duct thereof. This tube serves as a noz zle for conducting smoke into a chamber formed in the mouthpiece stem l. A rubber cap-shaped member 2 is fitted on the end of tube I5. 45 Washer 8, iilled with spongy material, sur rounds tube I5 and is adapted to absorb the prod ucts of condensation and the saliva. Cap-shaped members I and 2 are provided of the cowls or cap-shaped members I and 2 and the iiexible edges of the slits I’ and 2’ which al ways tend to come into contact are parted only through the drawing of the smoke. The matters suspended in the latter are held back by the fleXi- lo ble edges of the slits, and if by condensation or any other cause, an efflux of matters outside the cowls is produced, it falls into the reservoir 9. The pipe can be easily mounted and dismounted and its inner members cleaned or replaced by l5 others. The outlet vent of the cowls instead of com prising one or more slits may be a very small hole of circular or other section, provided that it has at least one flexible edge which, continually tend ing to close the vent, is parted only by the exhaus- H tion of the smoke. What I claim as my invention and desire to secure by Letters Patent of the United States is: In a tobacco smoking device of the character 25 described, a smoke conducting stem provided with upper and lower axially spaced chambers Con nected by a smoke duct, said lower chamber being divided into a lower liquid receiving reservoir, an intermediate smoke receiving compartment, and 30 an upper filter compartment, the longitudinal axes of said compartments and reservoir being coincident with each other and with the longi tudinal amis of said stem, a nozzle-like member for introducing smoke into the smoke receiving 35 compartment of the lower chamber, a rubber cap shaped member iitted on said nozzle-like mem ber, a nozzle-like iitting extending into the upper chamber for introducing smoke, passing through said duct from the lower chamber, into the upper 40 chamber, and a rubber cap-shaped member fitted onto said iitting, both oi said rubber cap-shaped members having a small smoke filtering chordal slit formed in the closed end thereof, said slits being normally closed and adapted to permit the 45 passage of smoke therethrough.
