To all whom it may: concern- Be it known that I, Fnaiaz RomzurScaUQ- MACHER, a citizen. of the United States, re-- sidin at Chicago, in the county of-Gook and tate of Illmois, have invented certain new and useful Improvements in Tobacco Pipes, of which the following is a specification.

My invention relates to improvementsin tobacco pipes and more particularly to pipes wherein a removable cleaner tube is provided for the herein the stem. g Y i One of the objects of my invention is so to shape the parts thatthe tube may most,

effectively clean the vpipe-stem,,andmay itself be cleaned with minimum. amountof trouble.. I

Anotherobject of myainventionis so to construct and arrange the parts.

whereinp Figure 1 is a longitudinal. central section of a straight-stem p' tion has been apphe .Fig. 2'is aperspective view of the cleanertube; Fig.- 3- is an enlarged fragmentary view of the ..end

, thereof; Fig. 4 isa perspective view of a stummel-protecting sleeve; and Fig. ,5 is a longitudinal central section of a drop bowl-portS', an aperture 15 being provided pipe having a curved bit.

-In the drawings, 5 indlcates ,the bowl, 6 the. stem,- and 7 the mouth iece or bit of a pipe, these parts being 0 any usual exto alittle beyond the perforation 8 commu- I nicating with the bowl; Such bore 8 may if desired have inserted therein a protecting lining or sleeve 9 prov'ided near its end with an a erture 10 for register with the perforation 8. The tube 9 is not necessary ex-.

7 cept where the material of which the stummel is formed requires greater protection than is afforded by the cleaner member to be described. For instance, meerschaum stummels may advantageously, be lined, but

arts that the. cleaner. tube has a. smoke-coo ing effect, acts effectively to connect the bit and 'st-ummeh and is readily detachable from both-said rpe to which my invenbriaifstummels serve well without the -linmg, as shown in Fig. 5.

The bit or mouthpiece 7 is formed to support the cleaner member which is to'engage 1n the bore of the stem, and to this end I prefer? ly make the bore of the bit tapered at .its end, as at 11,. for register with the bore of the stem, to effect frictional engage-' .cleaner tube provides a tapered portion 13 which is adapted to engage frictionally in thetapered. bore of the bit as above described. The cleaner tube 12 is thus carried byvthe bit. If necessary to reinforce the bit as where the'bit is of amber, say) a small it-protecting tube 14 may be used to line the bore, and as shown in Fig. 2 such tube may be an integral extension of the cleaning member, as shown in Figs. 1 and 2. This extension may, however, be dispensed with, and in Fig. 5 I have shown the application of myinvention without the tube and with a curvedbit.

tending beyond the bit into the stem bore is shaped to constitute a lining tube for the .bore of the .stem and preferably extends clear to the end of the bore beyond the in the tube to register with said perforation 8 to bring the interior of the cleaner tube into :-.com1nunication with the bowl. Between the tapered zone 11 and the perforation 15, the tube has longitudinal strips cut away, as at 16, to leave a plurality of longitudinal, parallel, separated ribs 17, which maybe bowed slightly outwardly to insure their spring-contact with the walls of the bore. To provide an end-cleaning blade, the end of the tube 12 is preferably partly closed as by turning down. ears 18 from the'cylindrical: portion of the tube, the two cars jointly to form a blade, and the cylindrical portion of the. tube, upon each side of the blade 18,'is preferably cut away somewhat as at 19, to provide suitable end openings.

In the use of a pipe provided with a cleaner as described, it will be observed that the cleaner tube may form the sole connection between the bit and stummel, making Wedge connection with the bit and slip connection with the stem. The passage of the smoke through the tube from the' aperture 15 to the bit will have a cooling and drying tendency by reason of the size of the chamher and the provision of the spaces 16 in which the smoke may eddy and deposit its moisture. When the deposit incident to use of the pipe has become great enough to partly clog the spaces between ribs 17 and the openings at the end of the tube 12, rotation of the bit and the cleaner tube carried thereby will cause the ribs 17 and blade 18 to scrape the exposed portions of the walls of the bore and gather up all of the semifluid deposit which may have adhered to them, so that when the cleaner is pulled out (by drawing back the bit) it carries all of the deposit with it, leaving the bore clear. I

The deposit within the lining may now easilybe cleaned oil as by washing under running water, the slits and end openings giving maximum access to the interior. Obviously, the cleaner may be detached from the bit simply by disengaging the coacting tapering surfaces 11-13, so that the tube may be cleaned apart from any of the larger parts of the pipe. I

While I have herein described an embodiment of my invention, it will be apparent to those skilled in the art that changes may be made therein without departing from the spirit of my invention and within the scope of the appended claims.

IVhat I claim is:

1. In a tobacco pipe, the combination with a bowl, a stem and a bit, said stem and bit having registering bores, of a tubular member engaging in the bore of the stem and bit, and removable from the stem, said member. having in its sides longitudinally-extensive lateral openings and ribs laterally deflected to provide resilient surfaces in frictional engagement with the stem bore. I

2. In a tobacco pipe, the combination with a bowl, a stem having a bore communicating with the bowl, and a bit having a tapering bore registering with said bore of the stem, of a tubular member having a plurality of resilient longitudinally extensive ribs, at one end frictionally engaging in said bore of the stem and having an opening for communication with the bowl and at its other end being tapered for frictional engagement in the tapering bore of the bit.

3. In a tobacco pipe, the combination with a bowl, a stem havinga bore communicating with the bowl, and a bit having a registering bore, of a tubular member having a portion tapered and making wedge engagement with the bit, and having another portion providing a plurality of spring members making frictional engagement with the stem. A

4. In a tobacco pipe, the combination with a bowl, a stem having a bore communicating with the bowl, and a bit having a tapering bore registering with the bore of the stem, of a tubular member, at one end engaging in said bore of the stem'and havin an opening for communication with the bowl, at its other end being tapered for frictional engagement in the tapering bore of the bit, and between its ends having laterally opening slits providing intervening ribs substantially as long as the bore of the stem.

5. In a tobacco pipe,the combination with a bowl, a stem having a bore communicating with the bowl, and a bit, of a cleaner member'for said bore carried by the bit, said member .being provided with longitudinallyextending laterally-bowed resilient ribs along a portion of its length.

6. Int. tobacco pipe, the combination with a bowl, a stem having a bore of substantially uniform diameter near its outer end, extending into communication with the bowl, and a bit having a registering bore, of a tubular cleaner member constituting a smoke-cooling'chamber, at one end engagin in the bore of the bit and at its other end engaging the stem to connect the two parts, said member having an opening for communication with the bowl, and between its ends being cutaway to form a plurality of slots and intermediate resilient ribs, said ribs engaging the interior of the stem and said member being rotatable in the bore of the stem and removable therefrom to gather up and remove the matter deposited in the eddy spkaces within the member and between the ri s.

7. In a tobacco pipe having stem and bit members with registering bores, a cleaner member having suitable openings at its ends,

said ends being formed for engagement in said registering bores in the stem and bit members, and said cleaner member between said ends having a plurality of long ribs separated by eddy spaces.

8. In a tobacco pipe, the combination with a bowl, a stem having a bore communicating with the bowl, and a bit having a tapering bore, of a cleaner member having a ribbed portion for frictional engagement in the bore of the stem and a tapering portion for wedge engagement in the bore of the bit,

said tapering portion merging into said ribbed portion, whereby said cleaner membermay be supported upon thebit by wedge engagement of its tapering portion in the tapered bore of the bit and the exposed portion of said cleaner member inserted into the bore of the stem, the frictional enga ement in said stem being less than the we ge engagement in the bit, for rotation of the cleaner in the stem by means of the bit.

9. A cleaner member for tobacco pipes.
