FREDERICK S. WHITNEY, OF NEW YORK, N. Y.

SMOKING IPIPE.

Application filed October 6, 1927. Serial No. 224,490.

This invention relates to tobacco pipes and has for its principal object to provide an improved pipe which will given a clean cool smoke.

Another object is to provide a pipe having an exterior tube or chamber through which the smoke is drawn, which tube is arranged and designed to act as a trap so as to prevent any particles of smoke condensation, nicotine, sediment, or tobacco from being drawn into the mouth with the smoke, and to prevent any saliva from entering the bowl.

A further object is to provide a readily detachable device of this character, which may be easily cleaned, and may be applied to a pipe of the usual construction and design.

Other objects will appear from the following specification, it being understood that various modifications in the construction described may be made without departing from the scope of the invention.

In the accompanying drawings, illustrating a preferred embodiment of the in vention:-

Figure 1 is a longitudinal section of the improved pipe; and,

Fig. 2 is an enlarged'cross-sectional View through the stem of the pipe.

Referring to the drawings, the pipe comprises a bowl having a barrel portion 2 and a detachable hollow stem 3. These parts may be of the usual or any desired construction or design, either straight or curved.

at is a removable plug or stopper which fits tightly in the bore of the barrel 2, against the internal shoulders 5, so as to close the usual direct passage from the bowl to the stem.

The improvement to which this invention particularly relates comprises the provision of a novel smoke chamber preferably consisting of an open-ended tube 6 extending longitudinally beneath the stem of the pipe and having removable stoppers or plugs 7 air-tightly closing both ends. The tube is formed with upstanding sleeves 8 and 9 adjacent its ends, which sleeves fit frictionally over the nipples 10 and 11 secured to and extending downwardly from, the pipe so as to permit of easily detaching the tube for cleaning. The tube may then be readily cleaned by removing the stoppers 7 and flushing with water. The nipples 10 and 11 are each prefer-ably, though not necessarily, tormed with a threaded upper end 12 as seen 111 Fig. 2, so that they can be unscrewed or detached from the pipe for cleaning. The nipple l0 communicates with the passage 13 leading into the bowl, while the tube 11 communicates with the passage 14; in the stem or mouthpiece 3.

The plug 4 has an end 4 which extends beyond the joint between the stem 3 and barrel 2 and into the stem. Hence, when the stem is removed, the end 4' of the plug can be conveniently gripped and the latter removed. The nipples have collars 10, which latter engage the stem and barrel, thereby limiting and assuring equal threading of the nipples into the stem and barrel, and also affording stops to engage the sleeves 8 so that the tube 6 will be supported parallel to the axes of the stem and barrel, and the sleeves will be held out of contact with the latter.

In using the pipe, smoke from the bowl is drawn into the mouth through chamber 6, which being located outside the pipe tends to cool the smoke, Condensation of the smoke takes place in this chamber and any particles of smoke condensation, nicotine, or other sediment are retained in the chamber and are prevented from getting into the mouth of the smoker. The chamber, furthermore, acts as a trap to catch any saliva that would otherwise enter the bowl thereby preventing the tobacco from becoming soggy and thus eliminating a cause of the objectionable odor of the ordinary pipe.

What I claim is An attachment for smokingpipes of the type having a bowl provided with a barrel and a stem removably connected at one end to the barrel, comprising a plug tightly fitted in the bore of the barrel and having an end 95 which extends across the joint between the barrel and stem whereby upon removal of the stem the said end of the plug extends outwardly beyond the outer end of the barrel so as to enable same to be grasped and 100 the plug removed, a pair of nipples each having a threaded end and a plain outer end with a collar between said ends, said nipples being formed to engage the inner threading of the nipples into the stem and barrel and to engage and limit sliding movement of the sleeves onto the plain ends of 10 the nipples, thereby to prevent contact of the sleeveswith the stem and barrel.
