SMOKING PIPE Filed June 27, 1952 Inventor www Attorneys Patented Mar. 13, 1934 PATENT OFFICE SMOKING PIPE Emerson Russell Wheelock, Nictaux Falls, Nova Scotia, Canada Application June 27, 1932, Serial No. 619,592 In Canada July 10, 1931 2 Claims.

The present invention relates to improvements in tobacco pipes and has for its primary object the provision of a pipe designed so that the saliva from the mouth of the smoker does not come in contact with the tobacco so as to afford a dry smoke at all times.

A further object of the invention is the provision of a pipe of the above Character wherein the smoke will describe a tortuous path between the tobacco containing bowl and the mouth of the smoker so that the smoke is relatively cool when it enters the mouth.

Another object of the invention is the provision of a tobacco pipe of the above type constructed so as to permit rapid and convenient cleaning of the interior of the pipe.

Still another object of the invention is the provision of a tobacco pipe which can be manufactured and sold at a relatively low cost.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a perspective View of the preferred form of pipe structure in smoking assembly.

Figure 2 is a central longitudinal sectional view therethrough,

Figure 3 is a view similar to Figure 2 showing parts of the pipe in separated relation,

Figure 4 is a transverse sectional View taken on the line 4-4 of Figure 2,

Figure 5 is a longitudinal section through a modied form of the pipe, and

Figure 6 is a perspective view of a tool especially designed for the pipe.

With reference to Figures 1 to 4 inclusive, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates the body of the tobacco pipe, which may be formed of briar wood or other suitable material.

At the rear end of the body 10 is formed a cylindrical bowl 11, in the normal position of the pipe arranged vertically so as to dene a tobacco receiving chamber 12.

Formed so as to extend from the rear end of the body, at an intermediate portion of the pipe, longitudinally or at right angles to the axis of the tobacco chamber 12, is a straight passage 14 having communication with the bowl, chamber 12 through the medium of the bottom open- .;ing. The inner end of the bore 14 registers with the inner or lower end of a complementary bore 15 arranged adjacent to and forwardly of the bore and extending parallel therewith. The bore sections 14 and 15 provide an angular passage screw threaded at the ends to receive threaded plugs 16 and 17.

At the forward portion of the bowl 10 is formed a stem section 19 provided with a bore 20, arranged substantially parallel with the axis of the bore chamber 12, extending from the upper end of the stem section to a point short of the lower end. The lower extremity of the bore 20 communicates with a longitudinally extending bore 21 formed in an elongated bottom stem section 22 extending below the bore. As will be noted from Figure 3, the stem sections 19 and 22 and the bores 20 and 21 formed therein provide an angular stem structure arranged forward of and below the bowl of the body.

To facilitate the drilling of the bottom steml bore 21 and cleaning thereof, the inner end of this bore preferably continues through the front wall of the body and is interiorly screw threaded, as indicated at 23, in order to accommodate therein a screw plug 24.

Mounted concentrically within the bore 15 and disposed parallel with the bowl is a rigid conduit forming tube 26, the lower extremity being exteriorly screw threaded and removably arranged in a screw threaded bore in the partition 27 between the bore 14 and the bore 21 so that the lower open end of the tube communicates with the lower bore 21. The upper endI of the tube 26 terminates below the lower extremity of the plug 17 in assembly, the exterior diameter of the tube being substantially reduced with respect to the interior diameter of the bore`15.

In the bottom of the bowl is removably positioned an annular plate or disc 29 provided with a central raised portion apertured at its centre and about the sides to provide communicating openings between the bowl chamber and the passage 14.

To the upper end portion of the forward stem section 19 is detachably connected a mouthpiece 30.

During the use of the pipe, the smoke is drawn from the ignited tobacco in the bowl through the perforations in the bottom plate 29 into the passage 14 from whence it travels into the connecting passage 15 entering the upper open end of the tube 26 and into the lower longitudinal passage 21, issuing through the upright stern passage 20 and the mouthpiece into the mouth of the smoker.

By describing this relatively tortuous path, the smoke is cooled before it enters the mouth of the smoker and saliva or moisture accumulating in the mouthpiece 30 is collected in the bottom longitudinal stem passage 21. Depos- 5 its from the bowl chamber and the smoke, such as ashes, nicotine and the like, will be collected in the passage 14 and may be conveniently extracted during the cleaning operation.

To thoroughly clean the pipe, the plugs 16 and 17 are disconnected from the body so that a cleaner can be inserted therein. The plate 29 can also be removed so as to thoroughly clean the bowl chamber. The saliva and moisture accumulating in the body may be conveniently removed by extracting the plug 24 and inserting a cleaner in the passage 21. The upright passage 20 may be likewise cleaned by disconnecting the mouthpiece 30 and the connecting member from the upper end thereof.

In order to facilitate the removal of the detachable parts, I contemplate the distribution of a special tool for this purpose, as shown in Figure 6. This tool embodies an angular elongated shank 32 having a relatively flat tapered blade 33 formed on one end engageable with the grooves in the exterior faces of the plugs 16, 17 and 24. Upon the opposed end of the shank is formed. an angular hook 34 engagea-ble with the central aperture in the raised portion of the plate 29 ior extracting Ithe plate from the bottom portion of the bowl chamber.

In the modied form of the pipe, shown at Figure 5, the body indicated at 36 embodies a bowl 37 and a forward projection 38 provided with a bore 39 arranged parallel with the bowl. The lower end of the bore 39 connects with a bore 40 extending below the bowl and communicating with the interior of the chamber thereof.

In this form of the pipe, the stem, indicated at 41, projects forwardly at right angles to the bowl and is provided with a straight smoke passage 42. A tube 43 is disposed within the bore 39 and is threaded in a partition between the bore 40 and the bore 42 so that the lower open end communicates with the stem passage 42.

It is to be understood that the forms of my invention herein shown and described are to be taken as preferred examples of the same, and that various changes as to the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:-

l. A tobacco pipe comprising a body formed with a tobacco receiving bowl at one end, the body being pro-vided with a longitudinally extending passage below the bowl and having communication with the bottom of the bowl, the said body also being provided with a passage arranged parallel with the bowl and communicating with the longitudinal passage, a stem formed on the body provided with a stem bore extending substantially parallel with the longitudinal passage and spaced therefrom, and a tubular conduit arranged within the said passage parallel with the bowl and having communicative connection with the stem bore.

2. In a tobacco pipe, a body including a bowl and a stem, the said body being provided with a passage below the bowl and communicating with the interior of the bowl, the said body also being provided with a vertical passage in communication with the passage below the bowl, the stem having a bore extending below the passage communicating with the bowl, and an open tubular 1 conduit disposed in and spaced from the sides of the vertical passage having the lower end arranged in communicative connection with the stem bore.
