TOBACCO PIPE FledMarGh 51. 1950 .Le l@ 4- mi INVENTOR Patented Dec. 13, 1932 PATENT OFFICE SVEND E. SVENDSEN, OF SEATTLE, WASHINGTON ToBAcco PIPE Application led March 31, 1930. Sierial No. 440,250.

This invention relates to tobacco pipes and has for an object, generally, the provision of a device of this character having improved smoking capabilities over pipes heretofore conceived.

A more specific object consists in the provision of means adapted to prevent the contamination of tobacco within the bowl from saliva produced in the mouth of the smokerf A further object consists in the provision of means for ready removal of such moisture and saliva as normally collects in the bit passage and stem of the pipe.

A still further object resides in the provision of structural features in adapting the pipe to a most effective and ready cleaning. IVith the foregoing and further objects and advantages in View, the nature of which will become apparent in the course of the following description and claims, the invention consists in the novel construction, adaptation and combination of parts hereinafter described and set forth in the claims annexed thereto.

In the drawing,-

Figure 1 is a longitudinal vertical section taken through a straight-stempipe constructed in accord with the present invention with parts broken away and shown in side ele- 3 vation. Figs. 2 and 3 are transverse verti' cal sections taken substantially on line 2 2 of Fig. 1, indicating valve apparatus in differing operative dispositions. Fig. 4 is a side elevation of preferred lapparatus in a curved-stem structure, parts being broken away and shown in longitudinal vertical section.

Reference being had thereto, the numeral 5 represents a pipe bowl having a body shank o projecting therefrom and representing a detachable stem-supporting bit or mouthpiece 8.

A tubular stem 7 is adapted for rigid sel, curement with respect to the bit 8 in any preferred manner, illustrated as a threaded extension 9 working in the internally screw threaded end of the latter. Said stem is composed, of any suitable material and arranged toproject through and adapted for seating '50 engagement with respect to spaced bearings 10, 11, disposed at substantially opposite extremities of a bored longitudinal passageway 12 of the pipe proper, the latter respectively communicating, as by vertically-aligned ports 13, 14 with the bowl chamber 15 and the atmosphere.

As illustrated, the wall of said stem is formed to provide, in the substantial vertical plane of the aforesaid ports, a valve opening 17 adapted for communication with respect to selective ports 13, 14, as by revoluble manipulation of the bit 8. A removable flanged plug 18 is indicated as provided a stud project-ion 19 arranged for insertion within the exposed extremity of the stem, a finger-receiving recess 2O accommodating ready removal of the same. A

With particular attention being had to Fig. 4, I represent a pipe bowl 51, curved body shank 61 and bit 81. A smoke passage 23 therethrough communicates with a valve chamber 22 for receiving the stud extension 21 of a plug valve 24, the latter constituting a sleeve 25 providing a valve aperture 26. As

illustrated, the ange extremity 27 provides a slot 28 for ready rotation of the valve into communicative disposition to selective ports 131,141.

In the operation of the pipe, such saliva as may enter through the mouthpiece will be retained in the stem 7, rotating valve aperture 17 into communicative disposition with port 14 allowing the operator to expel the same by blowing. In cleaning the pipe, the plug 18 is readily removedto allow the pas.

sage of a cleaner longitudinally of the stem.V

Removal of the bit and stem opens ports 13,

14, for passage of a cleaner vertically` through the same.

While I have described and illustrated the now preferred embodiment of the invention I do not wish to be taken as confining myself to the peculiar forms shown, except as taken by the scope of the hereto annexed claims.

What I claim, is,-

1. The combination with the bowl of a tobacco pipe having a tobacco containing chamber, said bowl providing a passage projected the length of said bowl portion and open to the atmosphere at both ends,

said bowl also providing vertically aligned ports communicating from the, chamber to the passage and from the passage to the atmosphere, of a bit for said pipe, a tubular 5 stem open at both ends and connected for conjoint rotary movement to said bit, said stem projecting into said passage for seating engagement therein and providing a port j opening adapted for selective register with l either of said vertically-aligned bowl ports, and a removable plug adapted to close the inner open end of said stem, said plug being adapted for removal to allow passage of a pipe cleaner through said bit and stem, said stem being removable to allow passage of a pipe cleaner through said vertically aligned ports.

2. In a smoking pipe, a bowl portion providing a tobacco-receiving chamber,said bowl portion having a passage running the length of the same below the chamber open at both ends to the atmosphere and also providing aligned ports leading from the chamber to the passage and from the passage to the atmosphere, said alignment of the ports accommodating introduction of a pipe cleaner through one and withdrawal from the other port, said open end passage accommodating introduction of a pipe cleaner through one end of the same for withdrawal from the other end, and means insertable in said passage for normally sealing one end of the saine and the port leading from the passage to the atmosphere, said means providing a smoke passage for drawing the smoke from said chamber.

Signed at Seattle, Washington, this 19th day of March, 1930.
