MOUTHPIECE FOR TOBACCO PIPES AND clean AND CIGARETTE Hotness Application filed May 29, 1931, Serial No. 541;037;an'din Great Britain A ril 7, 1931.1

This invention relates to mouthpieces for tobacco pipes and cigar and cigarette holders. The object of the invention is to produce an improved separable mouthpiece of the ".3 type wherein the mouthpiece is attached to the pipe or holder by a spigot and socket connection usually referred to as a push in fitting.

According to the invention the mouthpiece W is fitted with a spigot, preferably of metal,

which is split longitudinally to render it resilient and the free ends of the split portions are formed with external projections or otherwise suitably shaped. In the bore of the holder or pipe stem an abutment is provided,

To ena-ble the invention to be fully understood it will now be described by reference to the accompanying drawing in which Fig. 1 is a part sectional elevation of a I I, tobacco pipe having one form of the invention applied thereto, and

Fig. 2 is a similar view shewing a further form of the invention.

Fig. 3 is a part sectional elevation shewing the invention applied to a cigar or cigarette holder.

Fig. 4 is a View of one form of the improved spigot combined with a liner tube.

As shewn in Fig. 1 the mouthpiece 4 of the pipe 5 is fitted with a metal spigot 6 which is split longitudinally to render it resilient and the free ends of the prongs so formed are provided with external projections 7. The pipe stem 8 is formed with a socket or recess 9 and as shewn this socket is so shaped that when the mouthpiece is pressed home the projections 7 snap into the socket and are retained by the annular shoulder 10. The mouthpiece is thus held firmly in place and the parts can be separated by 5U a pull. The socket may be metal lined in any suitable" manner or the shoulder portion lfl fa'cedwith metal. 1 I

Fig. 2. shews a modification: wherein the recess or socketofFig. l is replacedby a metal 'ringlli whichis forced into the pipe stem, or fitted into a'sli'ght recess therein', so that: the edge 12' projects into the bore: of the stem and forms an. annular shoulder over which the "projections 7 of the spigot can Fig.8 shew-s the-arrangement of Fig. 2 applied to a cigar or cigarette h0'lden'13. Obviously the arrangement of Fig; 1 could I also be appliedito a cigaror: cigarette lio' l'der.

The spigot is preferably tapered and the projections thereon curvedor shaped toassist iin.the sliding action over the'annular shouleI'. I I

Preferably the spigotis slit in: such a way that the projecting" portion *consistsiof two prongs with a space. of substantial width be tween-them; This greatly facilitatescl'ean ing. However the-spigot maybe slitto form more than two prongs if desired- Withthe above described constructions itis unnecessary'to make any portion of' the' spigot iaitight fit with the bore of the stemor' holder, since the snap action. holds: thespigot firmly in the socket with the mouthpiece pressed against the'stem. or holder. Thus the-binding of the spigot on the stem or holder which frequently occurs in known :ar-rangernents is obviatedi The abutment in the pipe stem orbor'e maybe in the form; of an annular groove... r

Fig. 4 shews. -the combination of; he= split spigot with a liner t'ubeofknowh construction In this case the-lin'er tube 14 may be formed in one piece with "the spigot 15,. slits being provided at 16 and: projections at 17.

Silver, aluminium: or an y otlier suitable metal may be used for the spigot, or even wood or other: material provided it"i s 'si1.iii-' ciently resilient;

Further the abutment formediin the bore of thetstem maybe covered witlrnraterial holder, a stem, a mouthpiece separable from the stem, a spigot on the mouthpiece insertable in the stem and being split longitudinally to render same resilient, an abutment Within said stem, said spigot and abutment having cooperating means thereon for interlocking when the spigot is pushed home within the stem.

2. In a tobacco pipe, cigar or cigarette holder, aholloW stem having ashoulder therein with a recess inwardlyof the shoulder, a mouthpiece separable from the stem, a resilient spigot projecting from the mouthpiece for entry into the stem and being split longi- 7. As a new article of manufacture, a spigot, a liner tube forming a prolongation of the spigot, said spigot and liner tube being slit longitudinally to render same resilient, and projections on the slit portion of the spigot to enable sameto expand and contract.

In testimony whereof I have signed my name to this specification.

end adapted to snap back of said abutment when the spigot is forced home in the stem.

4. In a tobacco pipe, cigar orcigarette holder, a hollow stem, a metallic abutment lying within said stem, a mouthpiece separable from the stem, a resilient metal spigot carried detachablybysaid mouthpiece and insertable in the stem, said spigot being longitudinally 'split for a great portion of its length, such split portion opening outwardly through the outer free end of said spigot, said spigot also having external projections thereon for snapping back of said metallic abutment when the spigot is forced home.

5. In a tobacco pipe, cigar or cigarette holder, a hollow stem, a mouthpiece separable from the stem, a spigot on the mouthpiece for insertion in the stem, said spigot being split longitudinally for a portion of its length to render the same resilient, said spigot having projections on its splitpor tion, a liner tube extending beyond the split portion, and an abutment within the stem positioned to compress the projections on the spigot as the spigot moves into the stem and to interlock with such projections when the spigot is forced home.

6. In a tobacco pipe, cigar or cigarette holder, a hollow stem, a mouthpiece separable from the stem, a spigot carried by said mouthpiece for insertion in the stem, a liner tube carried by said spigot, said spigot and liner tube having longitudinal communicating slots therein, said spigothaving external projectionson its slotted portion, said stem having a recess therein, and a metal lining ring secured in the recess to form an abutment for interlocking with said projections.
