FREDERICK JuLrUs KALDENBERG, or TARRY'rowN, NEW YORK, AssIGNoR TO M.. KALDENBERG, OF SAME PLACE.

TBAcco-PIPE.

SPEGIFIGATION forming part of Letters Patent No. 552,711, dated January 7, 1896.. 4

Application nea March 6,1893.l serata. 464,856. (No model.) i l certain new and useful Improvements in Tobacco-Pipes, of which the following is a speciication.

My invention relates to pipes for smokers use, and the object of the inven tion is, in part,

air in regulated quantities to the smoke-passage inthe stem so as to'cool the smoke, and in part to provide aconvenient-construction whereby the nicotine distilled from the burning tobacco may be collected 'and-prevented from getting into 'the smoke-passage in the stem.

lThe invention will be fully described hereinafter, and its novel features carefully defined in the claims. Y

In the accompanying drawings, which serve to illustrate my invention, Figure lis a longitudinal section of a briarwood pipe embodying my improvements= and Fig. 1a is a transverse section through the stem thereof on the line l 1 in Fig. 1. Fig. 1b is a detached perspective view of the metallic screw which connects the sections of the bowl. Fig. 2 represents the mouthpiece and coredetached, and

, Fig. 2a is an end view of the core. Fig. 3 illustrates a slightly dierent construction of the core, the view being -a longitudinal section of the stem, core, mouthpiece, and a part of the bowl.

Referring primarily to the principal figures, and particularly Figs. l and 2, A represents, as a whole, the bowl of a pipe, which will. be,

by preference, of briarwood, or some woodl with a figured grain, and B the stem of the s pipe formed integrally with the bowl. .l The bowl A is' cut across transversely at this cut forming an upper section a, forming a receptacle for ,the tobacco, and a lower section ax,

forming a receptacle for the nicotine. -The stem B is connected withthis lower section ax. In the upper part ay is the cavity af to receive the tobacco or other substance or mixture to be smoked, and the bottom of this cavity is' Y the smoke topassdown into a cavity a3 inthe lower part ax of the bowl on its 'way to the smoke-passage in the stem.

It is desirable in wooden pipe-bowls, having a figured grain,.that the upper and lower parts of the bowl shall appear by the close--V ness of the joint and the continuity of the g'ured grain to be integral, and'in order to carry out this feature I first shape the bowl and stemof the pipe in the usual way and excavate the bowl to form the cavity c. `I then cut the bowl transversely along the line a: as

smoothly as possible, and afterward form the cavity a". sections of the bowl together, a screw (see at y.;in,Fig.3),is formed inthe wall of the cavity a, and a screw-threaded metal ring or tubesection a4 (seendetached in Fig. 1b) is set To secure the upper and lower y' tightly in the base of the upper section of the bowl in position to screw down into 4the cavity in the lower section of the same, as seen in Fig. 1. If necessary, the outer surface of the bowl may be dressed and finished after the sections are screwed together, so as to remove anyroughness about the 4joint due to inaccuracy in fitting.

In the cavity as a wad of cotton w may be placed to receive and absorb the nicotins, and this cotton may carry chemical substances designed to neutralize the nicotine.

C is the mouthpiece of the stem, and D is a 'core attached to said mouthpiece and designed tooccupy a bore in the stem B. Figs. l, 1, 2 and 2 illustrate the preferred manner of con' structing this core with a view to the admis-A sion of air in regulated quantities to` the smoke-passage in'the core and mouthpiece. In these views the main portion or body of the core D is cylindrical, and is adapted to fit snugly into the main bore in the stem lB. At its end is a short cylindrical portion d, which isl eccentric to the body and is adapted to e11- ter and t a counterbore in the stem, which counterbore connects the main bore therein with the cavity or chamber a in the lower section ofthe bowl. The core Dvhas a longitudinal slit d in it, which adapts the core to iit expansively and tightly in the mainbore of the stem when inserted, somewhat in the man-` ner of a split key. In the lower side of the core is formed a channel d', and in its upper sidey is formed achannel d2.- These channels communicate at a point near the mouthpiece with the smoke-passage c; The upper channel d2 extends to the end of the reduced por-- tion d of the core, and forms a smoke-passage to lead the smoke fromthe bowl to thepassage c, and the lower channel d' forms an airpassage, which will be hereinafter described. It will be seen that the wall of the bore in the stem B forms one wall of the respective smoke and air passages, the channels d' and d2 being open grooves in the core. These grooves may be much more cheaply and conveniently home the entry of air to the passage h is cut oi. Any known device of this character may be employed, that shown being preferred.

Fig. 3 shows a construction slightly dierent from that already described. The part d is omitted from the core D, and the core is not slitted longitudinally. Otherwise there is no material diEerence.

The construction of the core with the part d insures its proper insertion in the stem, and the slitl insures a snig it in the bore of the stem. l

I t will be seen by inspection that while the large bore in the stem of the pipe is open bot-h to the bowl and the air-inlet -the core, when inserted, interposes a barrier between said air inlet or passage and the passage leading from the bowl to the groove d2, thus compelling the smoke and air to traverse the respective grooves in the core to the point where they unite with the smoke-passage c.

Of course I do not limit my invention to wooden pipes; but in many respects it is well 5o adapted to this class of pipes.

Having thus described my invention, I claimv 1. In a pipe, the combination with the stem having a relatively large borewhich communicates at itsinner end with the bowl of the passage, and a core D, secured to saidmouthpiece and adapted to iit snugly in the enlarged bore in the stem, said core having two longitudinal passages, d and cl2, both communieating at their outer ends with the smokepassage in the mouthpiece, the former communicating at .its front endwith the air-inl et to the stem, and the latter communicating at its front end with the bowl of the pipe, substantially as set forth.

2L In a pipe, the combination with the-stem, having a relatively large bore which communicates at its inner end with the bowl of the pipe and bya lateral passage in the stem with the air, and a mouthpiece having in it a smoke-passage, of a core D, secured to said mouthpiece, said core having a short cylindrical portion d, which projects beyond the main portion into the bowl, and said core having also two separate passages, d and cl2, for the air and smoke, respectively, which passages connect at a point near the mouthpiece with the smoke-passage therein.

3. The combination with the stem and bowl of a pipe, said stem having in it a relatively large longitudinal bore, communicating at its inner end with the bowl and by a lateral passage, with the air, of the mouthpiece, and the core, D, secured to said mouthpiece, said core having a longitudinal slit dx, two oppositely arranged longitudinal grooves, d'andd, and a smoke-passage c, with whichv said channels communicate, as set forth.Y

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
