TOBACCO PII'E.

Application tiled August 8, 1927. Serial No. 211,421.

This invention relates to smoking or tobacco pipes, and nioi'e particularly to pipes adapted to be used in either right-side-up or upsidealown position.

5 The objects of my invention are to provide a` tobacco pine of the character referred to consisting of few simple and inexpensive parts, which in ay be easily assembled or taken apart, for cleaning or renewing a worn or broken portion, together with simple and efficient means for cleaning the pipe and for collecting and discharging or draining liquid or moisture therefrom, and means for producing a cooling effect upon the smoke in its i5 passage from the bowl to the mouthpiece and preventing the unpleasant or biting effect of hot smoke on the tongue or the roof of the mouth, or the entrance of nicotin or moisture and saliva into the mouth, and also preventing the clogging up of the smoke channel while producing perfect combustion and more satisfactory results than are attainable with tobacco pipes as heretofore ordinarily constructed.

The invention will lirst be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the endof the description. i

In said drawings, Fig. 1 is a side elevation of a tobacco pipe embodying my invention; the bowl beiner shown in inverted position in full lines. while its upright position is indi cated in dotted lines;

Fig. Q is a longitudinal sectional view of the pipe shown in Fig. 1 in up-side-down position;

Fig. 3 is a longitudinal sectional view illustrating a modification of the invention;

Fig. 4 is a detail view of a broken-away portieri of the bowl of the pipe shown in Fig. 3;

Fig. 5 a vertical sectional view of anx. other modification showing the bowl and stein of a pipe having a curved smoke channel;

Fi 6 is a detail plan view of a broken-away endportion of the mouth-piece; and

Fig. 7 is a side view of a preferred forni in of spring with a nipple adjustably secured thereto.

Referring to said drawings, in which the same reference letters are used to denote corresponding parts in different views, the letter A. in Fi l and 2, denotes the bowl with ,integral stem c and detachable extension al which terminates in a preferably wide mouthpiece a2 having several smoke ducts therein, though other forms may be used. The several arts mentioned are similar to corresponc ing parts of ipes of known constru tion `and they are s own associated with co`` operating elements embodying my invention, winch 1 will now proceed to describe.

As shown, the bowl A is provided with a lining B which may be constructed of metal, preferably aluminum, and of cylindrical or conical form. To facilitate cleaning the pipe and to keep the smoke channel and the inlet thereto at the bottom of thebowl open `and free from clogging matter, I insert in the smoke channel a resilient device of tubular form, preferably a spiral or coiledspring C, which extends through the stern a across the bottom of the bowl and has the convolutions thereof which are within the smokechanncl in close contact, while the convolutionswhich are exposed within the bottom of the` bowl are separated sutiiciently to provide an intersticed construction adapted to permit air and smoke topass freely` therebetween into the inlet end of the smoke channel, while preventing the entrance of bits of tobacco or matter tending to close the same; thereby providing a spiral construction within the bowl throu h which air and smoke may enter the smo e channel,` which is preferably lar er than usual, and also providing a practica 1y tubular body serving as a lining for said channel and forming a conduit connecting the bowl with a smoke and liquid receiving chamber D .in the pipe stem, to receive nicotin and saliva or moisture drawn `into the stern. The spring C extends entirely across the bottom of the bowl to the rear wall thereof and may be held against the bottom of the bowl when the pipe is in upside-down position by the lining B abutting thereagainst at its lower end, as shown in Fig. 2. To the outer end of the spring C is secured, by soldering or otherwise, a disk or washer e, the periphery of which is soldered toor otherwise fixed within a sleeve or ferrule E, which connects the outer end of the stem a with the inner end of a mouth-piece `oreirtension aiof the stem formed integrally with the mouthpiece a2. The disk or washer e, attached to the spring and ferrule, has a hole through the center thereof arranged in 4alinement with the smoke channel to permit the passage of smoke therethrough, and has secured thereto co-incfident with said hole the larger end of a tubular cone or nozzle G1, which provides a tubular extension of the smoke channel formed by the spring C. The sleeve or ferlule E spans the space between the stem and month-piece so as to provide a clear space around the cone or tubular tube C1 and provide a chamber D to receive liquid or lnois ture exuding trom the slnoke channel. This channel, owing to the contacting convolutions of the spring and the conical :form ot the nozzle C1 tends to retard the flow of smoke through such channel, and, in connection with the liquid chamber D, produces a cooling ettect upon the smoke before it enters the extension oi the smoke passage provided by the extension uit of the stem ol' the mouthpiece secured thereto. The liquid or moisture exuding trom the smoke cllallnel is collected in the liquid chamber D and may he discharged from time to time by either disconnecting the stein and terrule or mouth-piece and shaking the moisture out ot the stem ol without disconnecting said parts, giving the stenl a sidewise thrust so as to eject the moisture through the smoke passage in the mouthpiece. The open end ot the bowl has secured thereto av cap or cover Gr, wllich is preferably hinged to the bowl at the stein side thereof and provided witll a snap spring g on the opposite side in which there is a depression adapted to snap over a protuberance on the outer side ot' the bowl alld thus prevent the cap or cover from becolning loose and dropping down so as to spill the burning tobacco when the pipe is in the upside-down positioll. The cap G is provided with numerous pertin-ations .for the admission ot air, and within this cap is placed a body of reticular material such as Vwire netting, 0r the like, ot circular 0r other tol-m adapted to contorni to the sllape ot the cap and having on the circumferential edge thereof a cylindri Ial tlallge, whereby it properly spaced 4trom the ill/lpert'orate end-portion of the cap which terms the bottoni of the bowl when the pipe is in up-side-down position, tllus providing a false bottom for the bowl when in the latter position and a support therefor by which it is sustained above the in'lpertorate bottoln so as to provide all air chamber below the bowl when in up-side-down position and above the bowl wllen the pipe in its normal upright position. In either position the operation o't the pipe is very nlucll like that ot a stove, the wire netting or retieular material acting the same as a grate in a stove, and thus a goed draft is insured, similar to the draft of a chimney. `When the spring C is inserted in the stem a the sleeve or errule E, wllich is secured to the outer end of the spring, is forced over the end of the stein while the outer end of the sleeve tits tightly over the inner end of the extension a? ot the stein or the mouth-piece so as in etl'ect to unite the two parts as one, thus adapting the same to servi as a handle tor removing the mouthpiece and withdrawing the spring when it is desired to clean out the bowl and smoke chaunel. I thus provide a iirln airltight connec tion between the terrule and extension oit the pipe stein while at the salue time the two parts are adapted to he Yforcibly disconnected.

In the form shown in Figs. 3 and il ot the drawings, instead oit' a hinged cap or cover, the cap has its cylindrical body portion extended so as to overlap the howl to which it is secured by means ot a bayonet joint connection, as shown at I ill Fig. 4; otlnfrwise the construction ot the cap is substantially identical with the cap previously descrihed. Furthermore, in this lnoditicatioll, the exit end or terlninal C ot the snfloke channel formed by the spring C is oi tubular torni instead o'tI the conical torni shown in Fig. Q; otherwise the Lfollstruction sllown in Figs. El 85 and 4 is substantially identical with the construction shown in Figs. l and Pleterahly the outer end ot the mouth-piece is lattened sntlieiently to provide small duets on opi-insite sides of an intermediate duct ot larger size forming a continuation of the smoke channel through the stem, so that smoke is drawn ill larger volume through the intermediate duct and a part caused to pass through the side ducts, which are very small ill proportion to the size oit the intermediate duct, so that the smoke issues from the lnouth-piece in a divided stream instead of being concentrated and caused to issue through one large duct.

In the lnoditication shown ill Fig. 5 ot the drawings, the pipe howl A2 is formed integrally with a curved stein o* having a smoke channel which is curved throughout its length, and in which is inserted a spring ofthe same construction as that described with reference to Fig. 2 ot the drawings; the resiliency ot the spring or clplivalent device, such as a tube torlned ot' wire netting or ther retieular material., permitting the'insertion thereof in a curved smoke channel.

Fig. 'T ot' the drawings illustrates a spring` such as shown in Figs. 2. 3 and 5. having adjustahly attached thereto, a tthe delivery end of the smoke challnel` a nozzle or nipple C ol elongated tubular torni so as to provide at one side ot the disk or washer e, a delivery or discharge end-portion c alld on the other side a shank portion el, the latter having iormed thereon or secured thereto studs or pins c', which are adapted to enter between adjacent convolulions or coils ot' the spring, inv one end of which the shank portion of the, tube inserted. so tha` t by rotz'lting the nipple while the spring held stationary, or vice versa, the studs or pills will be caused to move spirally following the coil ot the spring while the nipple moves in the direction ot the axis ot the spring. either t'or ward or back, according to the direction ot rotation, thereby adjusting the spring so that it may extend a 13e fit) greater or less distance into and across the bottom of the bowl as may be found desirable in practical use. In this instance the delivery end of the nipple or nozzle has secured thereto, by solderinglr or otherwise, a detleetor or baille plate c3, against which the smoke impinges as it passes out of the smoke channel into the liquid chamber I); said baille plate having on opposite sides thereof rearwardly extending flaps or flanges c* which are soldered or otherwise secured to the tube so as to leave a .narrow space between the discharge end ol the nozzle and the baille plate.

As the smoke contacts with the baille plate it is deflected or turned back into the liquid chamber wherein it is condensed and cooled, thereby producing a dry cool smoke; the moisture aud nicotin being separated by contact with the batlle plate and caused to drip or drop down into the bottom of said liquid chamber.

In the preferred form of my invention I use the ni pple of elongated tubular form having the dellector or baille plate on its outer or delivery end, while its inner end is adjust-- ably secured to the outer end of the coiled spring, but I do not desire to be limited to the particular form described, as other forms may be employed, and obviously the baille plate may be attached to nipples of the form shown in Figs. l and Q, with or without the adjustable connection with the spring.
