Application filed November 18, 1950. Serial Io. 148,244.

, The present invention relates to improve ments in tobacco pipes and has particular reference to a means for trapping'moisture when the same forms in the stem or mouthpiece of a pipe, either by fluid secretions of the mouth entering the pipe through the mouthpiece, or by condensation which occurs when the heated vapors from the burning tobacco pass from the heated bowl into wcontact with the cool surfaces of the bores of the stem and the mouthpiece of the pipe. The precipitation of moisture in any pipe of ordinary construction is undesirable to the user. This is because the presence of m accumulated moisture clogs the bore of the stem ormouthpiece and, thereby impairs the draft through the pipe; to the end that poor combustion of the tobacco takes place in the bowl en this occurs the smoker usually exerts a series of relatively poweri'ul draws or pufis' through the pipe and these invariably operate to draw the distasteful moisture from the mouthpiece into the smokers mouth. 'In other instances, as where the pipe, while not in use, is placed horizontally in a coat pocket or upon a desk or table, accumulated'moisture within the pipe finds its Way into the mouthpiece from w ence it is readily drawn ,into the mouth upon relighting of the pipe.

Comin now, to the present invention, the general 0 ject thereof is to provide a means for coupling the stem and mouthpiece of a pipe and to adapt the coupling means to opcrate as a trap or receptacle for li uids moving through the mouthpiece tower the stem or from the stem towards the mouthpiece, and further to adapt the coupling means to provide a support for holding the mouthpiece and the stem upwardly and at an incline when the bowl is arranged upright upon a horizontal support such as a desk 0 table. V

The above and other objects are accomplished by the instrumentalities pointed out in the following specification.

The invention is defined in the claims.

A satisfactory embodiment of the invention is illustrated ,in the accompanying so drawings forming part of the specification and of which:

Figure 1 is a view showing the pipe in side elevation together with my invention connected thereto and disposed to support the pipe upwardly upon a table or support.

igure 2 1s a view similar to Figure 1, on p a slightly enlarged scale and showing the invention in longitudinal section and connected to the stem and mouthpiece, the mouthpiece and stem also being shown in longitudinal section.

Figure 3 is a detail cross-section on line 33 of Figure 2, looking in the direction of the arrows.

In the drawings, a indicates generally a tobacco pipe comprising a bowl 5, stem 6 and mouthpiece'7. These parts are all of well-known construction and may be formed of any of the materials usually employed in the manufacture oi? these parts. The fluid collectorof the present invention is desig nated generally by b and comprises a body 8 7.

and mouthpiece together.

For, purposes of illustration I have shown the several parts as being provided with slip joints for connecting the said parts together. This construction is clearly shown in Figure 2 where it is to be noted that a reduced end of portion 9 of body 8 is slipped into a recess 10 in the stem'6 and a re need end portion 11 of the mouthpiece 7 slips into a recess 12 in anend portion of body 8 remote from the reduced end of portion 9. The end portion of the stem 6 adjacent the body 8 may be provided with the usual ferrule 13. As thus described, the body 8 forms a continuation of the stem 6 or the mouthpiece 7.

The stem 6 is provided with the "usual axially disposed bore let-which is in axial alinement with the bore 15. of the mouthpiece 7. The body 8 is provided with a bore 16 in axial alinement. with bores 14 and 15. A counter-bore 17 is disposed adjacent the mouth iece 7- and functions as an expansion or con ensing chamber for the smoke stream p of the stem 6.

towards the bore 15 of the mouthpiece. The inner end of the counter-bore 17 provides a circular shoulder 18 which operates to arrest or intercept fiuld that may move through the bore 15 of the mouthpiece and towards the bore 16 of body 8 and bore 14 A duct 19 extends outwardly through body 8 from the counter-bore 17 and operates to convey the liquid away from the counter-bore 17. The end portion of bore 16 adjacent to the stem 6 is also counterbored as at 20 so as to provide a circular shoulder 21 which operates to intercept liquid that may flow through the bore 14 and towards the mouthpiece 7. Aduct 22 extends from the counter-bore 20 outwardly through body 8 and provides a passage for. liquid entering the counter-bore 20 and in-' tercepted by shoulder'21. The body 8 is formed with a laterally disposed and exteriorly screw threaded boss 23. The ducts 19 and 22 extend through the end surface oi the boss 23 and when the body 8 is properly connected to the stem. 6 and mouthpiece 7, the boss 22 will occupy a position on the underside of the body 8 as shown in the drawings. I

A receptacle 24 formed of metal or an other material found suitable for the purpose is open at one end and interiorly screw threaded as at 25 and adapted to be screwed upon the screw threads of the boss 23. With this construction it is obvious that the re-' ceptacle will depend from the pipe when the same is arranged in the position it ordinarily occupies in the smokers mouth, so that the liquid entering the ducts 19 and 22 is conveyed downwardly and outwardly and into the receptacle 24. I The bottom 26 of the receptacle 24 is flat. In the present instance I have shown the bottom 26 disposed so as to incline toward the stem 6 so that when the bowl 5 is arranged to extend upwardly on a horizontal support such as a table'27, the receptacle will operate to sup port the stem 6 and the mouthpiece 7 in an upwardly inclined direction when the bottom 24 of the receptacle is placed in contact with the surface 27. It is to be noted that the ducts 19 and 22 diverge from the end of the boss 23 and are ob ique to the axis of the bore 16 and the axes of the counter? bores 17 and 20. This construction provides for the easy cleaning of the bore 16 and ducts 19 and 22 with the ordinary form of flexible pi e cleaner.

en pipe (1 is in useand inserted into 4 the smokers mouth, the smoke stream passes through the bores 14, 16 and 15, it being understood that the screw threaded connection between the receptacle 24 and the boss 23 is adapted for providing an air tight connection between t ese parts.

Condensation forming in the counter-bore tering the counter-bore 17 from passing into the bore 16 when the pipe is arranged as shown upon a horizontal support 27; it being I obvious that the liquid entering counter-bore l7 readily passes into the receptacle 24 through the duct 19.

From the foregoing it is obvious that a device of the present invention is adapted for elfectively preventing liquid from flowing through the mouthpiece 7 into the smokers mouth and the several parts are so constructed as to permit easy cleanin thereof,

it being obvious that the receptac e 24 may be readily cleaned when detached from the boss 23. The several passages of body 8 may be cleared of moisture or articles of tobacco without the use of a exible pipe cleaner in that body 8 with the mouthpiece 7 attached thereto may be withdrawn om the stem 6 and the passages cleaned by blowing through the mouthplece 7. In carrying out this form of cleaning it is desirable to close the outer end of the reduced ortion 9 by placing the same in contact with the palm or a finger joint of one hand. .It is to be noted that the device of the present invention is of simple construction and may be manufactured at. a minimum of cost. Its use with any of the prevailing forms oi tobacco pipes employing a mouthpiece and stem, involves but slight changes in the construction of these arts in order to adapt them for use with t e device.

Although I have shown and described one embodiment of my invention, it is to be understood that same is susceptible of various changes and I reserve the right to employ such of these as may comewithin the extension and having a bottom oblique to the axis of said bodyand formed to support a pipe in association with the pipe owl,
