vApplication filed` August 16,1906. Serial No. 330,867.
v To all 'whom it may concern: y
` tains to make land use the same.
- scribed and claimed. Y
The object of the invention is to provide a pipe of this character which may be quickly and easily cleaned i This invention relates to improvements in tobacco smoking pipes, and consists inthenovel construction, combination and arrangement of parts hereinafter deand in which the temperature of the smoke may be readily controlled, so that the smoker may enjoy a cool l smokeand secure the full pure beneiit of the tobacco.
The above andvother objects which will appear as the nature of my invention is better understood are accomplished by means of the construction illustrated inthe accompanying drawings, in which:-
Figure lv is a side elevation of the improved pipe; Fig. 2 is a top plan view of the same; Fig. 3 is a vertical longitudinal sectional view; Fig. 4 is a horizontal sec- A tion. Fig. 5 is a detail, horizontalsection through a slightly modified form ofthe invention.
In the practice of the invention, vI provide lthe pipe with an outer bowl 1,. an inner bowl 2 and air spaces or channels 3 between'these bowls. The outer bowl or body 1 of the pipe may be of any suitable form and construction and may have a stem 4 which may'also be of any suitable form and construction. The inner bowl or cup 2 in which the tobacco is burned is ,formed of some durable material'and has at its topan out-turned .annular flange 5, which rests upon the top of the outer bowl or body 1, as/seen in Fig. 3. The air passages 3 are provided for the purpose of permitting a circulation of air between the two bowls. of the pipe, so that the temperature of the inner one will be reduced. .These passages may be produced in any suitable manner. As
shown in Fig. 3' they are produced by forming upon the inner wall of the outer bowl l vertically extending V-sliaped ribs or corrugations 6, the points'or edges of which engage the outer face of theinner bowl 2, which latter is here shown in the form of a cylinder, but which may be of other shape.` As showninFig. 5, the passages 3 are formed by makingvertical grooves or channels in the inner wall of the body l. -In both cases, the channels 3 extend vertically from the bottom of the body 1 to its top and thus provide a pluralityrof ues for carrying 0E the heat generated by the burning tobacco in the bowl 2. The passage of air currents through the passages or channels 3 is made possible by providing in the center of the bottom 8 an opening 9 and by forming in the flange 5 of the bowl 2 an annular row of apertures or openings 10, which latter alinewith l the passages 3; also by forming in the body l adjacent to its top an annular row of transverse'openings 11, which communicate with the upper'ends of the passages 3, as clearly shown in Figs. 3 and 4. As indicated by the arrows in Fig. 3, currents of cool air will pass upwardly through the opening 9 and the passages 3 and then out through the openings 10, l1, carrying off the heat from the inner bowl 2.
While the construction above described materially` reduces the temperature of the smoke, I'prefer to iurthr reduce it by admitting cool air into the bowl of the pipe adjacent'to its bottom, especially after the tobacco in the bowl 2 has been partly consumed'. I
preferably e'ect this by providing an inlet 12 at a4 suitable point adjacent to the bottom of the pipe. This opening 12 is here shown in the form of a tube extending across one of the channels or passages 3 and having its open ends secured in the inner and outer bowls. I-tis adapted to be closed or opened by a removable closure of any description, as here shown it is in the form of a removable plug. The air inlet 12 is preferablyl arranged-at a point diametrically opposite the opening 14 in thestem 4 of the pipe, so that a cleaning wire or the like may be passed through the alining .openings 12, 14'to facilitate cleaning the pipe.
InAuse, the tobacco is packed in the inner bowl 2 in the usual manner and the plug or closure 13 is placed' in the opening l2. After the tobacco has been about half consumed, the temperature of the smoke increases` to -a noticeable extent notwithstanding the cooling effects of the air currents passing through the air passages 8 as previously explained. When this occurs, the plug 13 may be removed from the opening 12 to admit air into the bottom of the pipe. This air mingles with the smoke and cools it, so that the pleasure Vof the smoker is materially increased. The opening412-aside from acting as a feeder of cool air to theover-heated smoke, serves as a damper to break or modify the supply of air through the open top ofthe bowl 2 and also as a perfect. means of cleaning the pipe by inserting a cleaning Wire or the like as previously stated.
Various changes in the form, proportion and the minor' details of construction may be resorted to without departing from lthe .principle or sacrificing any of the advantages of this invention, .as defined by the appended claims.
Having thus described my invention, what 4I claim as new and desire to secure by LettersfPatent, isz- 1. A tobacco pipe comprising an outer bowl having openings near the top thereof and a central air inlet. in its bottom, an inner bowl spaced from the bottom and side walls of said outer bowl and having an annular flange at f its top to engage the top of the outer bowl, said flange having apertures therein registering with the spaces between'thebwls, and a stem connected with said bowls.
2`. A tobacco pipe comprising'an outer bowl having a stein projecting therefrom and vertically extending ribs upon its inner wall, an inner bowl engaged with the edges of said ribs and having an annular Bange' at its top to engage the .top of the outer bowl, said flange having :iperg tures to aline with the spaces between said ribs, said outer bowl having in its bottom a central air inlet opening to afford communication between the atmosphere and the lower ends of the spaces between said ribs, said outer body also having adjacent to its top transverse openings to aord communication between the atmosphere and 'the upper ends of the spaces between said ribs, an air inlet Y \VILLIAM CLARKE MAISHALL.
