c. H. MORRIS Oct. 9, 1951 SMOKING PIPE Filed Aug. 1, 1945 INVENTOR O. H. More I5 A TTORNE Y Patented Oct. 9, 1951 2,570,47r sMofiING are Karate-s aii iist'r, 1945',- Seria V 2 Claims. c1. aa-3 ,This invention relates to smoking pipesand means incorporated thereon for receiving and a bing the 'deleterious fluids resulting from salivaintermixingwith the nicotine as formed by the burning tobaccb'jinthebowl of the pipe, andso that-suchfiuids 'will'not be drawn into the mouth of the smoker.

The principalbbject' of'the' invention is to provide a'smoking" pipe' with filtering means at the bottom of the bowl and adjacent under side of the bore oi the stem tor-absorbing any moistures as generated in the smoking. of the pipe, thus providing a. dry smoke, preventing such moist"es fromascendingthe stemjoff the pipe to the niputhiofjthe user 'and; preventing the caking of'burned tobacco within'thebowlof the pipe.

; Anotherobject of the invention is to provide a smoking pipe so formed at the lower endor bot.- tom'of" the bowl and along the under side of the adjacent portionLoithe stem, ..that a filter element, Qf any suitable absorbent material may be inserted or interposedatitliellower end of the' bowl andalon'the' upderjsidejor the adjacent portio'if'of the stern rbr receiving and absorbing any nicotine charged fluids or moisture that may be formed in the lower end of the bowl and stem in the process of smoking, thus preventing same from ascending the stem to the mouth of the smoker and also preventing the caking of burned tobacco within the bowl of the pipe, the said filter element being removable and renewable from time to time as required, and the pipe easily cleaned.

With the stated objects in view, together with such other and additional objects and advantages as may appear from the following specification, attention is directed to the accompanying drawing as embodying certain preferred forms of the invention, and wherein:

Figure 1 is a longitudinal vertical section of a smoking pipe constructed in accordance with one preferred form of my invention.

Figure 2 is a cross section on the line 2-2 of Figure 1.

Figure 3 is a top plan view of the removable filter supporting tray, tongue or leaf, for slidable insertion at the lower cut-away end of the pipe bowl and adjacent portion of the lower side of the stem.

Figure 4 is a plan view of the form of filter as used upon the filter supporting tray, tongue or leaf, the same being made of any suitable absorbent material, and being replaceable.

In practicing this invention, the conventional form of smoking pipe which includes the tobacco 1 i "r V. i are enameled out" flatly and longitudinall as i e-waxlwh c co n es b and'thelunder itsoii (Fig 3) i to ,fit into the c t r e dsi e 1 e rms}? a t element 9 as shown Figure 4, audi the B 1}.- of the filter supporting tray or leaf 8";"as shown in Figure 3. This tray or leaf 8 is preferably pierced through with a plurality of spaced air holes But from end to end for facilitating the evaporation of moistures as accumulating upon the absorbent filter elements 9. The filter elements 9 are positioned upon the tray or leaf 8 within the raised margins 8b thereof, and the tray or leaf is then slidably entered into the slideway 1, whereby the filter element is operatively located immediately below the lower end of the bowl 5 of the pipe and the lower side of the adjacent portion of the bore 6a of the stem 6, so as to readily catch and absorb any moisture or nicotine laden fluids that may gravitate through the bowl from the burned tobacco therein, thus preventing such moisture or liquid from passing up through the stem to the mouth of the smoker. The outer end margin of the tray or leaf 8 is pierced with a screw hole So for passing a screw H] which is threadedly seated at its inner end into the lower end of the pipe bowl, thus releasably locking the tray or leaf removably in position.

In the form of the invention as shown in Figures 5 and 6, the tray or leaf 8 is omitted, and the base of the conventional pipe bowl and adjacent integral stem portion, 5e, lie, is merely slotted up vertically as at 6d to provide a narrow groove or channel for frictionally receiving and holding a filter element 9a which is in the form of an elongated strip that is pressed evenly up into said channel. The slot 6d of course extends up through the bottom of the bowl e and through the under side of the bore (if of the stem 6e, for catching any moisture generated in the pipe bowl.

In the form of the invention as shown in Figures '7 and 8, a'slot 6h is formed flatly and laterallythrough the lower end of the bowl and the under side of the bore 62' of the integral stem portion 67', perpendicularly to the axis of the bowl and opening into the lower end thereof and into the under side of the bore, thus providing a fiat recess opening out laterally through the sides of the pipe structure and through the rear end thereof, as clearly shown in Figure '7. This fiat recess or slot 6h is thus well adapted for slidably receiving and frictionally holding the hat filter element 9b which is cut to suitable dimensions to fill the recess and to project marginally therefrom in order to facilitate the removal of a used filter element and the insertion of a new one. I ""From the foregoing description and accompanying drawing it is thought that the construction and use of the several forms of pipes will be fully understood, the essential function of the said constructions being to provide means in the way of absorbent filter elements for interposition beneath the tobacco receiving portion of the bowl of the pipe and extension Within the stem thereof, for receiving and absorbing the nicotine charged fluids resulting from the buming of the tobacco in the bowl of the pipe, in which function the apertured tray or leaf of the first described form materially assists by admitting air directly to the under side of the filter element.

And while I have here shown and described specific forms of the invention and the embodiment thereof in smoking pipes, the structural features of the invention as shown may be changed or modified as desired, within the scope of the claims.

I claim:

1. A smoking pipe having the usual round and hollow tobacco bowl and bored stem leading therefrom but cut away on the underside of the bowl and adjacent length of the stem to form a flat slideway exposing substantially the full diameters of the bowl hollow and the bore of the stem, a tray element removably mounted upward against saidslideway and having in its upper suriace a recess round at one endto correspond to the shape of the exposed hollow of the bowl and narrow at its other end to correspond to the stem shape, and a filter element positioned in said recess and having a round end exposed to the bottom of the bowl and a narrow end portion fitting beneath the stem whereby the filter element will be intimately exposed to the bowl and adjacent bore through the stem to rapidly absorb the juices and fluids incident to smoking of the pipe.

2. A-smoking pipe according to claim .1 in which the tray element has a plurality of openings exposing the filter element to atmosphere for evaporating such fluids.
