Application February 14, 1940, Serial No. 318,786

This invention relates to a smokers pipe and relates particularly to means for insuring a clean dry bowl in Aaddition to `providing a smoke ltering means rso arranged that the vfiltering .medium may not be'ignited from the bowl and at the same time may be veasily ll'ed and discarded.

These and other objects of the invention will 4become apparent to those `versed in the art in the following description of one particular form of the invention as illustrated in the accompanying drawing, in which Fig. 1 is a top plan view of a pipe embodying the invention;

Fig. `2, a central, vertical, longitudinal section; Fig 3, a top plan view of the cleaner tube; Fig. 4, an end lView of the tube on an .enlarged scale;

Fig. 5, a top plan view of a modified form of the cleaner tube; and

Fig. 6, an end view of the `modied tube Fig. 7 is a perspective detail View of a position of the modied form.

Like characters of reference indicate like parts throughout `the 'several views .in the drawing.

The bowl IIJ of the pipe may assume any desired form but in any event it is provided with a floor II centrally sloping downwardly to the side .thereof nearest the. pipe stem. The bowl I8 is providedpwith a vstern extension I2, herein shown as being integral Awith the bowl part Il). This stem extension `I 2 :is ybored axially to form a comparatively large bore therethrough and so located that 'the upper inner end of that stem bore cuts .through and opens into the lower end of the bowl III by a comparatively small hole I3. In other words the top of the bore lthrough the extension I2 is a trifie above the lowermost part of the-licor II in the bowl IB,

A .mouthpiece I4 is made out of any suitable material and is formed to have a `cylindrical end I5 of a diameter that will permit it to engage frictionally within `the bore of a tube I6. This tube I6 is preferably made out of arigid material, such as metal, Vand has an external diameter approximating that ofthe bore in the extension I2. By inserting the `Vtube I6 within the bore of this stem extension I2, frictional engagement is had within that bore, lparticularly by that part of the tube I6 which surrounds the end I5 of the mouthpiece I4 so that the mouthpiece 'I4 may be removably seoured in position and there maintained in the desired relation with the bowl ID.

The tube I6 is cut away ahead o-f the mouthpiece end I5, Figs. 2 and 3, to leave a longitudinal opening into the tube. Referring to that form of the tube as shown in Figs. 2 and 3, in cutting away the upper part of the tube I6, a tongue I'I is left and given a periphery that will cause the tongue to t snugly against the wall o the tube in an inclined position when that tongue is pushed down into the tube to have its lower end come into contact with the floor of the tube. The tongue I'I thus forms a partition across the tube I6 including upwardly and outwardly toward the tube end. Then the tube is provided with a groove I8 pressed downwardly in that part of the top side of the tubebetween the tongue and the end of the tube.

.In practice, the mouthpiece I4 is removed to The tube le is then 1 up and ll the spacethereabove to .the full diameter of the pipe when the pipe is being used. The tubel I6 `is then inserted within the bore of the stem extension I2 to bring the mouthpiece I4 into 2 its proper position, as .indicated in Figs. 1 and 2. The bowl I Il is lled with tobacco and smoked in the usual manner. The mouthpiece I4 carries the usual small diameter passageway 2D therethrough. Should all of the tobacco be consumed within the bowl I0, the tobacco within the tube IG will not become ignited from the last burning tobacco in the bowl I by reason of the fact that the tongue I'l serves effectively as a partition to form a small chamber in the front end of the tube I5 free of tobacco or ltering medium so that an airgap is thereby had between the pipe bowl lil and the filtering medium within the tube I5. The groove I8 is of suiicient length to prevent any substantial transfer of heat from the pipe bowl to the lteringmedium.

Should for any reason the small hole I3 in the bottom of the bowl Ibecome clogged, the mouthpiece I 4 may be axially revolved so as to rock the tube end across .fthehole I3 `and thereby clear the hole. The tube I6 may be withdrawn by pulling out on the mouthpiece Ill and then the ltering material knocked out. Not only do the shoulders I9 at the sides of the groove I8 on the forward end of the tube I6 provide an excellent means 4for cleaning the interior of the pipe, but they also may be used eiectively by inserting the tube l-G downward-ly within the bowl I0 to clean out the bowl itself Referring to the modified form of the lter carrying tube as shown in Figs. 5 and 6, the forward end of the tube I6 may be formed in any other suitable manner to accomplish the same result as above indicated, such for example as by cutting longitudinally through the top of the front tube portion and then bending one side of the tube downwardly and inwardly to form the retaining nger 2| which enters in a V-slot 2,2 formed in a plug 23 that serves as a partition member in place of the tongue I1. The plug 23 preferably has its inner face sloped upwardly from the iloor of the tube and forwardly. 'The plug is so proportioned in size as to leave a small chamber 24 in the front end of the tube as indicated in Fig. 5. This form leaves a sharper cutting shoulder 25 4at the front end of the tube. In any event, whether either form be employed, the ltering medium can be thrown out of the tube very readily by giving it a jerk to allow the material to slide on up over the tongue I 'I or the partition wall 23 so that no gouging or picking around in the tube I6 is required to clean it.

Should for any reason the tube I6 through use become loose within the bore of the stem extension I2, the free sides of the tube I6 between the front and rear ends thereof may be spread laterally so as to engage the wall of the bore more securely` Thus it is to be seen that I have produced a very simple yet eiiective pipe construction, free of the usual difficulties, all without any complicated mechanisms or minute passageways, and while I have herein shown and described the invention in the one precise form, it is evident that structural variations may be employed, such for example as varying the formation of the cutting end of the tube and the forward partition, etc., all without departing from the spirit of the invention and I, therefore, do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.

I claim:

1. For a pi'pe having a pipe stem and a bowl with' a oor above the bore in the pipe stem and a lower opening at the junction of the inner bowl wall and its iloor for communication between the bowl and the bore of the pipe stem, a lter holding element consisting of a tube open at its rear end, and having a central top longitudinal opening intermediate front and rear tube end portions, an imperforate wall across the front end portion of the tube closing off the maior bore of the tube from its under side, and a depressed top part of the tube extending rearwardly longitudinally from the front end of the tube over said wall, said tube being of a diameter to i'lt snugly by its front and rear ends at least within that pipe stem bore whereby there is a smoke discharge passageway provided from said bowl through said bowl opening downwardly onto and over said depressed tube part over said tube front wall and into the tube and out through its rear end portion, whereby a filtering medium may be placed in and removed from said tube through its said longitudinal opening.
