Patented Nov. 1, 1932 UNITED starts rarest QFFICE JOHN L. DORSCHEL, OF KITCHENER, ONTARIO, CANADA v oHEoK- vALvE For; SMOKING ARTICLES Application filed January 12, 1931, Serial 180. 508,889, and in Canada February 20, 1930.
My invention relates to improvements in check valves for various uses, and the principal object of my invention, broadly considered, is to provide a very sensitive check valve for use in locations relatively restricted in size or difficult of access, and one that can be easily and quickly removed for cleaning, repairs, or replacement, to control the flow of air, gas, smoke, or liquid through a conduit, and in the following specification and the drawing forming part thereof, I
shall disclose the principle of my invention as applied for use particularly in a tobacco pipe, and what I claim as new will be set forth in the claims forming part of this specification.
Fig. 1 is a vertical longitudinal section through the major portion of a tobacco pipe showing my invention combined therewith.
0 Fig. 2 is a horizontal longitudinal section on the line 22, Fig. 1, and Fig. 3 is a cross section on the line'83, Fig. 2.
In the drawing, like characters of reference refer to the same parts.
It is well-known that the tobacco in the bottom of the bowl of an ordinary tobacco pipe becomes soggyand the stem clogged with a nicotine collection by reason of the saliva from the mouth flowing down through the mouthpiece and into said bowl.
The result is a waste of tobacco, and the 1 smoking under such a condition is not as free nor as pleasant as it should be.
I have illustrated the application of my invention to a tobacco pipe to show that the saliva from the mouth of a smoker can not flow down into the mouthpiece of the pipe, and the consequence is, no waste of tobacco, and a free and more pleasant smoke will be had. a
2 is the bowl of the pipe and 3 is the stem. Formed in this stem is a passageway comprising an inner section 1 leading from the bowl to section 6 of greater diameter and length. 7 is the mouthpiece, and this is provided with theiusual extension 8, which snugly fits into the stem 3.v 9 is a passageway formed within the mouthpiece 7, and extending from one end to the other end thereof but of uniform diameter as far as the shoulder 11.
Theinner portion 10of the passageway9 is slightly tapered from substantially the shoulder 11 to the shoulder 12 and is of smaller diameter'than the said passageway beyond said shoulder 11. r p Mounted within the passageway 9 and long enough to extend into section 6 is a conduit 13. The inner end of this" conduit is inserted within the inner tapered portion 10 of the passageway '9 and therefore since the conduit 13 will be made of suitable material, for example, aluminum, the portion located in the inner portion 10 will be firmly held in place so that noair can pass between these 1 The inner end 16 of the conduit 13 is formed at an angle less than a right angle, and concaved as shown at a, Fig. 2, so that the ball check 17 will seat thereagain'st perfectly while resting on the'bottom of chamber 18, and prevent any saliva flowing down into the conduit 13, Fig. 1. The chamber 18 is formed in the passagewayt) and" extendsfrom the shoulder 12 of the tapered portion 10 to the shoulders 5, Fig. 1, said chamber having a greater horizontal than vertical diameter. This greater horizontal diameter extends from'the shoulder 12 and beyond the should ers 5 into the passageway 19, Fig. 2*, so asto provide plenty of room' for the passage of smoke around the ball check 17 as it is drawn against the shoulders 5 when the pipe 'isin use. s
This construction provides the passageway 18 centrally longitudinally with upper'and lower aligned grooves centrally'in alignment with the outer end of the conduit 13, which grooves outwardly terminate at the shoulders 5, and as the ball check rolls in these grooves its line of travel is essentially always such as to compel it to seat against the concaved end a, of the conduit 13;
- The extreme inner end of passageway 9 is in the form of a flat conventional passage F way 19 having its vertical diameter smaller than the ball check "17 and extends from the shoulders 5 to the end of the mouthpiece '7. It will be easily understood when the pipeis in use, the ball check 17 will be limited in its movement from its air tight seat against the conduit 13 and the shoulders 5. This distance is approximately double its own diameter, Figs. 1 and 2. i
The section 6 of the passageway through the stem 8 forms a smoke-collecting chamber and it will be noticed upon reference to Fig. 1, that this chamber extends beyond the end 20 of the conduit 13. In order that the smoke which collects in section 6 may pass into the conduit 13 I provide this conduit with a suitable number' of perforations 21 Theseperforations act as a screen to prevent any ash or small particles of tobacco passing through said conduitand hinder the free movement of the check valve. The end 20 isnot perforated, thereby forming a cupor pocket in which may accumulate any condensation within the conduit 13. This condensation may be readily removed from the conduit by inverting the pipe and shaking it.
o The passageway 9 from its extreme outer end to the shoulder 11 is of greater diameter than the'external' diameter of the conduit 13,
ber and adapted to co-act with said seat and said shoulders, for the purpose specified.
2. A mouthpiece 7 having a passageway therethrough from one end to the other, portion of which is tapered, said passageway laterally enlarged from the inner end of said tapered portion to form a chamber, the balance of said passageway from said chamber having a diameter less than the diameter of said chamber thus forming shoulders; a conduit located within said mouthpiece and having its inner end held in said tapered portion, the inner end of said conduit being formed at an angle less than a right angle to form a seat, and a'check valve located in said chamber to co-act. with said seat and limited in its inward movement by said shoulders, for the purpose specified. i I, 7 JOHN L. DORSCHEL.
thus forming a sleeve for the conduit 13 which isvspaced apart therefrom equally on all sides. in a v c If desired, .the portion 14 of the conduit 13 may be threaded into the associated portionof'the passageway in the mouthpiece, in place of being plain as illustrated.
The principle of my invention is appli- 7 cable also to cigarette and cigar holders, and of course may be adapted to tobacco pipes of different shapes. 7
This check valve may also be used in various other ways for the control of'liquids,
gases, air, smoke, etc.
. Changesin design or construction may be made without departing; fromthe spirit of my invention. v What I claim as my invention is r 1. In a tobacco pipe, in combination a bowl provided witha stem, said stem being proios vided with a passageway opening from said bowl; a mouthpiece adapted to be coupled to said stem, and having a passageway therethrough from one end to the other portion of which is tapered, said passageway near the inner end of themouthpiece enlarged to form a chamberofgreater diameter than the diameter of saidpassageway in said mouthpiece, the balance of the passageway in said mouthpiece from said chamber having a diameter less than the diameter of said chamber thus forming shoulders; a conduit having a closed outer end and having apertures through which smoke passes, located I in said stem and mouthpiece and spaced apart therefrom forthe major portion of its length, the inner end of said conduit being located in the said tapered portion of the passageway through said mouthpiece, and having itsinner end located in said-tapered passageway formed at an angle less than a right angle so as to form a seat, and a check valve located in said cham-
