Application September 14, 1951, Serial No. 246,640
1 Claim. (Cl. 131-223) This invention appertains to improvements in smoking pipes and has for its primary object to provide means for preventing saliva from entering the bore in the stem of a pipe, without interfering with the burning of tobacco in the bowl or the smoking of the pipe.
Another object of this invention is to provide a ball check valve in the bore of a pipe stem, the valve preventing saliva from entering the bore but being easily drawn out of an obstructing position in the bore when a smoker draws smoke through the stem.
A further object of this invention is to provide a modified pipe stem, which can be constructed without any more considerable expense than a conventional stern and to provide a valve assembly that can be disposed in any conventional pipe stem.
These and ancillary objects are attained by this invention, the preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawing, wherein:
Figure 1 is a side elevational view of a pipe, illustrating the end of the stem in section to depict a valve assembly therein, in accordance with this invention;
Figure 2 is an enlarged sectional view taken on line 22 of Figure 1;
Figure 3 is a longitudinal sectional view above the valve;
Figure 4 is a transverse sectional view taken on line 4-4 of Figure 2, and,
Figure 5 is an enlarged longitudinal vertical sectional view showing the check valve in an inoperative position.
Referring now more particularly to the accompanying drawing, the numeral designates the removable mouthpiece section of a pipe stem 12, the section being formed with a bore 14, which opens through the end 16 thereof.
Adjacent the end 16, a circular seat 18 is formed in the bore to accommodate a ball check valve 20, which is formed from a suitable rust proof material.
A recess or bore 22 is formed obliquely in the section 10 adjacent the end 16 and communicates laterally with the bore 14. The recess is slanted upwardly and rearwardly from the bore, when the pipe is properly disposed in the mouth, the bowl facing upwardly. The recess 22 is of a diameter slightly larger than the ball 20 to receive the ball 20 and is closed off at its outer end by a threaded plug 24, the plug having a kerf 26 in its outer end to facilitate removal thereof for removing the ball 20 from the stem.
In use, the ball 20 seats in the seat 18 and closes off the bore 14 so that saliva cannot enter the bore. However, when a smoker draws on the pipe, the ball will be sucked up into the recess, the seat camming the ball upwardly, as it reacts to the suction. The ball is formed from a light weight material, so that it does not offer any considerable resistance to a draw on the pipe.
Of course, while only one embodiment has been illustrated and described, other embodiments can be resorted to, so that limitation is sought only in accordance with the appended claim.
Having thus described this invention, what is claimed In a smoking pipe, a mouthpiece having a smoke duct longitudinally therethrough, said mouthpiece at the tip end thereof being formed with an upwardly extending rearwardly directed recess communicating with the smoke duct, and a ball having a diameter slightly larger than the diameter of said duct and slightly smaller than that of said recess, whereby said ball will be moved into said recess when air is drawn through said duct, said recess being disposed at approximately a forty degree angle with respect to said duct and of sufiicient length to wholly receive said ball therein.
