SMOKING PIPE Filed Aug. .2o. 1929 y INVENTOR GEORGE E. BALDWIN ATTORNEY Patented Nov. 24, 1931 UNITED STATES GEORGE E. BALDWIN, or sEArrLnWAsIIINGToN SMOKING PIPE I ApplicatoniledAugust 20,1929. i Serial No. 387,232.

This invention relates to improvements in smoking pipes and it has reference in particular to pipes of that character designed for filtering, purifying, iiavoringand cool- ,5 ing the smoke; the principal object of the inventionbeing to provide a pipe of the above character having a smoke passage designed to hold a capsule containing a purifying composition through which the smoke, in its del livery from the pipe, is causedto pass for the removal of dust andV other impurities which are apt to irritate the throat of the smoker, and to cool and flavor the smoke and to retain within the capsule all moisture and l those resinous andtarry substances which are the products of combustion 'and which are a detriment to comfort and pleasurein smoking.

It is also an object of the invention to pro- Y vide a capsule for the purifying. composition, that is of such construction that it may be easily and readily removed from the pipe for refilling or for replacement and to so design the chamber within which it is contained, and to so arrange the smoke channels of the pipe with respect to the inlet and outlets of the capsule that the smoke drawn from the pipe bowl will be caused to pass downwardly through the filtering substance 3D throughout the length of the capsule and will then flow upwardly through a plurality of outlet channels and to the outlet in the pipe stem, the capsule retaining the moisture and impurities. Y

Other objects of the invention reside in the various details of the construction of Vthe capsule which prevents its passages becoming clogged and which insures an easy drawing of smoke through it. A still further object .40 is to so arrange the capsule with respect to the outlet at the base of the bowlof the pipe that the port opening into the capsule may be easilyy and readily cleaned out withoutA necessitating removal of the capsule from the pipe and also without necessitating thedis` connection of any parts of the pipe.

Other objects of the inventionV reside in the variousdetails of the construction and in the relationship of parts as is hereafter described.

- portion Qfis provided with the usual cuplike' Thelower section 16 is of cup-like'character In accomplishing these objects, I have provided the improved details of construction the preferred forms of which are illustrated -in the accompanying drawings, wherein F ig. 1 is a perspective view of a smoking 65 pipek embodied bythe present invention.

Fig.l 6 is a sectional detail of a modified construction.

Referring more in detail to the drawings 1 designates, in its entirety, a pipe constructed in accordance with the present in- `vent-ion. It comprises the usual bowl portion 2, a base portion 3 to which the bowl is 75 attached and from which the stemportion 4 extends; there being also the usual mouth piece 5, threaded or otherwise attached to the stem as an extension thereof. The bowl chamber 6 for containing the tobacco to be smoked and centrally ofthe base of the bowl 2 is an extension 7 that is threaded into the upper end portion of a chamber 8 formed within the base portion 3 of the pipe.V This" S5 chamber S is designed to contain the capsule, presently to be described in detail.

its shown best in Fig. 2 there is a channel 10 leading centrally from the bottoni ofjthe chamber 6 andopening centrally into the'top of the. chamber'S. There is also a channel 12 leading through the stem 4 and mouth piece 5 and this opens into the chamber 8 closely adjacent to the top wall of the chamber.;

In its preferred form of construction the?" Vcapsule which contains the smoke treating composition is formed from two metallic, opposite end sections 16 and k17' telescopically ittedtogether to forml a closed container.

with a cylindrical body portion and a rounded base or lower end portion adapted to seat upon the base or bottom wall of the chamber 8 which is shaped to receive it. rlhe upper section 17 is of cylindrical shape and is fitted telescopically within the base portion. It is provided with an upwardly crowned upper end wall 18 provided centrally with a conical tip 2l forming a central opening 22. This conical tip fits snugly within a conical seat Q3 at the lower end of the channel '10, leading Jfrom the pipe bowl, and it forms an airtight connection therewith; it being supported in place by contact oi the base of theV capsule with the bottom wall of the chamber 8.

The chamber 8 is of such diameter as to loosely contain the base portion of the capsule and about the upward end portion of the capsule the chamber forms an annular space 25 with which the channel of the pipe stem communicates.

The upper section of the capsule extends substantially within the base portion of the lower section and it is provided with a plurality of vertical grooves 24, in its outer surface, leading from the lower end to the top wall, and these grooves provide outlet channels for the smoke after it has been drawn downwardly through the purifying composition. These grooves preferably would be formed by pressing the metal of the cover section inwardly as shown best in Fig. 5, but might also be provided in the walls of the lower section to produce the same result.

In the preferred fo m oi the construction of the capsule it is intended, that the base section extend well toward the top ot the capsule so as to retain all the moisture and other products of combustion. However, other constructions might be employed, one of which isillustrated in Fig. 6, wherein the upper section 17 iits within a very shallow base portion 3() which is downwardly rounded and is perforated and there rests upon a lat bottom surface of the chamber 8.

It is to be understood that various details of construction of the pipe and of the capsule might be changed without departing from the spirit of the invent" on and for this reason it is not desired that the claims be limited only to the details which have been shown and described. For instance, the pipe bowl might be applied to the base portion in a friction tight fit. instead oi by threading; the stem portion. might be curved instead of being straight and the mouth piece might be attached, thereto, by a friction joint instead of by threading; the top wall of the capsule might be made flat and the top wall ot' the chamber be crowned in order to provide the annular channel which communicates with the outlets of the capsule and with the channel of the pipe stem; in the event that the capsule, as disclosed in Fig. 6, be used, the

chamber 8 might be provided in its side walls with channels corresponding to and serving its purpose oi the groove 24 oi the capsule.

The principal features of the present construct-ion or the advantages to be gained thereby are:

The capsule is so designed as to retain all dust., moisture and all those tarry and resinous products which are detrimental to the enjoyment ot smoking; the capsule at all times retains its smoke purifying contents and there is no possibility oi the smoke outlet channels of the pipe being clogged thereby; the inlet to the capsule may be easily cleaned by use oi' a match or other pointed instrument projected through the channel at the base or" the bowl; smoke entering thc capsule through the single port at the top must pass downwardly and through the purifying composition before leaving the capsule and the provision ot a plurality of outlets overcomes the possibility of obstructing the flow of smoke; the design of the capsule and the chamber which contains it is such as to provide an annular channel about the` upper end ot the capsule with which all the outlet grooves connect anc which has an unobstructed connection with the pipe stem channel.

With the capsule so designed and fitted within the pipe, should it be desired to remove it for replacement or for refilling, it is necessary only torcmove the bowl and to invert the base portion so that the capsule will drop out. vWhen the capsule is replaced and the bowl threaded into place the capsule automatically centers and seats itself to form the airtight connection with the lower end of the channel l0. if there should be any looseness this may be taken up by placing a layer of paper at the bottom oi' the chamber 8.

While l have not illustrated such a construction, it is quite apparent that ay capsule substantially like that of Fig. 2 or of Fig. 6, but without the bottom cap, could be em ployed with goed results, so long as it was grooved, or tne chamber walis grooved in a manner which would provide the various out lets for the smoke. Such a device would still serve as a iiltor and would permit clearing of the bowl passage l() by punching any material clogged into the passage down into the capsule. Vhile such a capsule would not have the moisturea'etaining ability of the closed one, it would serve as a container for the iiltering material and would cause the smoke to be drawn through it on passing to the stem.

Having thus described my invention what I claim as new therein and desire to secure by Letters Patent is l. A pipe oi i the character described formed with a. bowl, a chamber beneath the bowl anda channel leading from the bowl into the top of the said chamber, a stem having a channel opening into the chamber, and
