11 Claims.

This invention relates to improvements in tobacco pipes. The draught or suction of such pipes is frequently impaired through a clogging which takes place at the bottom of the pipe bowl, and particularly at the junction of the bowl and the pipe stem, which clogging is due to the continual accumulation of various ingredients distilled out of the tobacco during the smoking. Those accumulated ingredients have to be frequently scraped out of the pipe-bowl, as, besides impairment of the suction, they also form hard or viscuous masses which seriously vitiate the taste of the tobacco.

The principal object of our invention is to provide a tobacco pipe with improved and-efficient means for remedying the above mentioned disadvantages.

Another object is to provide a tobacco pipe having simple, inexpensive, reliable, efficient, and improved means for retaining an absorbent material for remedying said disadvantages, and for readily, rapidly, and conveniently discarding and renewing said material.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,-

Figs. 1, 2, 3, 4 are longitudinal cross-sections of tobacco pipes embodying the above referred improvements, all of which forms are modifications of this invention.

Fig. 5 is a similar view of a tobacco pipe embodying a further modification of the invention.

Fig. 6 is a perspective view showing a modification of a detail of the invention.

The upper portion I of the bowl 2 of the tobacco pipe 3, Fig. 1, is severable from its lower portion 4 along the plane 5. Between the pipe portions I, 4 is situated an annular framing 6 which is secured to the portion l by means of a flange 1 thereof lodging within a recess 8 in the underside of said portion, and the framing extending into the interior of bowl-portion l and having a flared lip 9 which is pressed into and "from the lower bowl portion 4. A tablet l3, madeot any suitable absorbent and non-com- ,bustible material, such as mineral fiber, is

frusto-conical in configuration and adaptedto fit into the tapered bore Hl'of the framing 6. In the floor i4 of'lowerbowl-portion 4 is located a peg [5 which is threaded thereinto by a shank l6, and said peg serves to hold and retain the tablet H3 in requisite position within the .bore !0 against any accidental downward dislocation. When it is required todiscard the tablet l3 for renewal of a fresh tablet, the user may merely separate the portions 8, 4, by unthreading the former from the latter, whereby the used tablet :3 will drop out, and a new one may then be reinserted and the portion I threaded back upon the portion 4 in the position shown.

In the modification shown in Fig. 2, the usual pipebowl 2 is provided in its lower portion H with an annular upwardly tapered bore l8, which is adapted to receive the frustro-conical tablet 13 in the manner shown. And said tablet is retainedin this requisite position by means of a fitting! which threads into the floor 20 of the pipe bowl and is provided with a lug 2| upon which the tablet rests. The fitting I9 is preferably provided with a knurled head 22 for its manipulation. To renew the tablet l3 it merely requires unthreading of the fitting [9,discarding of the old tablet, reloading the new one, and then threading back the saidfitting.

According to the modification illustrated in; Fig. 3, the bowl 2 is provided with a fire pot or internal secondary bowl 23 which is located therewithin and removably held in place by means of a threaded collar 24 thereof screwing into a tapped rim .25 of bowl 2, a rim 26 of bowl 23 abutting against the edge of the bowl 2 to limit the internal movement of the fire pot. In the floor 21 of the pct 23 is provided an annular tapered bore 28 adapted to receive the frusto-conical tablet l3 in the manner shown, and a lug 29 formed upon the floor 36 .of thebowl 2 projects upwardly and against the underside of the tablet, thereby retaining it in requisite position within the bore 28. To renew this tablet it merely requires unthreading the fire pct 23, discarding the old tablet and recharging the new one, and then replacing the fire pot to the position shown.

The modification shown in Fig. 4 is particular- ,ly adaptable for equipping corncob pipes with the improvements of this inventiom as the material of such pipes is quite weak. The corncobbowl 2 is provided in its floor 3! with an upwardly tapered bore 32 in which is fitted a similarly shaped framing v33 adapted to receive the frustro-conical tablet [3. ,A metallicplate framing 34 consists of a ferrule portion 35and a spun threaded shank 36. Said ferrule 35 embraces the exterior of the lower end of the corn cob bowl 2, and the threaded shank 36 similarly embraces a lug 3! of said bowl surrounding its bore 32, by which means the upper bowl portion 2 may be threaded into the lower bowl portion 4, which may be made of any suitable material. The edge 38 of the shank 36 is adapted to support the framing 33 against any downward dislocation.

In the modification shown in Fig. 5, the tablet I3 is sustained in its requisite location within the framing 6 by means of a lug i3a forming part thereof resting upon the floor of the bowl, in the manner indicated.

Fig. 6 illustrates a modification of the framing 6, in which is provided a plurality of vent grooves 39, whereby an absorbent tablet may be utilized in which the outer conical surface is flush, rather than corrugated, as illustrated in all the other views.

It will be evident that by the provision of an upwardly frusto-conical tablet l3 being retained within a similarly configurated pocket of the bowl any accidental dislocation or dropping out of the tablet during use of the pipe will be precluded, and by the provision of a special framing or retaining means 6, 24, or 32, which may be made of metal or any other suitable non-combustible material, the tobacco pipe will be protected and a firm and eflicient holding means for the tablet will be at all times secured.

With the above provisions the tobacco carried in the pipe above the tablet l3 has its objectionable ingredients distilled out therefrom by the absorbent material of the tablet. All the clogging of the pipe at the junction of its bowl and stem is in this manner prevented and impairment of the suction obviated, and the suction is further improved by the numerous vents l3b of the tablet [3. With the use of these improvements, the bottom of the bowl will be always found dry and free from all objectionable hard or viscuous foreign matter which is ordinarily found in pipe bowls and vitiates the taste of the smoking.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
