Heights, Ohio Application December 13, 1934, Serial No. 757,321 1 Claim. (01. 131-12) My invention relates,

and the like, such means stems, cigarette holder stems, cigar in its broadest aspect to for the bite end of pipes being adaptable to pipe holder stems and the like for the purpose of protecting the tongue and the mucous membrane lining of the oral cavity of a smoker prevent the smoke from out direct from In the smoking of a pipe from irritation, and to eri'ng into the mouth the pipe stem or holder. 1

and the like, it is a well known fact that all pipe stems and the like at the bite end have a tendencyjo wear down the teeth of a smoker,

has no teeth, then th of the smoker.

Therefore the object of and further, bite end irritates the gums if the smoker this invention is to provide a means whereby the smoke stream from a tobacco in a pipe bowl, orfrom a cigar or cigarete is hafiied or diverted irom'a horizontal plane into a vertical plane,

plished by means of V smoke regulator.

It is also an object smoking? more pleasant by be diverted from one plane verting thereof causing such diverting being a'ccomn expansion chamber in the of the invention to make causing the smoke to to another, such diit to eliminate some of the nicotine contained therein.

It is also a means on, in, or

invention to provide bite end of a pipe stem and thereof which will save the wear on the incisal or occlusal edges or surfaces of the teeth used in holding a pipe or the like in the mouth.

1 upward into the egress and 'an efficient and compact is to permit moist air from the oral cavity or mouth or a smoker to enter into the expansion chamber, such tending to prevent a further rise of the pressure in the chamber, while at the same time serving as a regulator so that the mixture of 5 smoke and moist air are simultaneously moved thence into the mouth.

It is also an object of the invention to provide smoke regulator for the bite end of a pipe stem and the like having an interlockingmeans therein so as to enable it to be easily mounted on or in the pipe stem andinterlocked therewith, such mounting beingsimple in construction, easily manufactured-and easily re-v stem and integral therewith, and when thus zo made, then to insert or mount a covering means on the outside of the pipe stem for the purpose of protecting the teeth of a. smokerfrom wear.

It is to'be observed therefore in the present type of smoke regulators for use on pipe stems like, that their purpose is merely for sanitary purposes as well as to save the teeth, so that other than the results outlined the devices are generally considered unsatisfactory-from the standpoint of a smokers comfort. ,Therefore to overcomesuch defects, the type of smoke regulator used and which is the subject of this invention is constructed of rubber, or rubber compound, or elastic plastic compositions. It has considerable elasticity, and as well as being made of the above compounds, it may also be made of any other suitable compound or com- It is also an objector the invention to provide a pounds means, which when placed 0 end of 'a pipe stem and the n, in, or with the bite like will increase the length oi the smoke travel from the pipe bowl or the like to the mouth It is also an object of the a means which may be attached or in a pipe stem and the like and of the smoker.

invention to provide a pipe stem and the the purpose of which In the invent'on I find that elastic rubber is advantageous since it may be easily molded into the 4 desiredshape and because of the convenience with which it may be applied and maintained in its desired position. It ismade to it on the outside with strict conformity to the shape of the pipe stem and/or the like, and may be mounted detachably thereon, or it may be mounted in the end of the pipe stem, or it may be made integral with the pipe stem. A conventional shape as applied to a standard pipe stem ure 1, and from whichit will be observed that it comprises top,side,bottom and an end wall which fits closely to the general contour of the stem end.-

It must fit snugly upon or in the bite end of a pipe stem so as to exclude air and moisture from 55 and the 25 illustrated in Figentering in between the regulator and the pipe stem.

It may be of integral or composite structure, and 1 may likewise be suitably colored.

Other objects will present themselves, from a perusal oi this specification and claim, to those skilled in the art.

In the accompanying drawing, an illustrative example is shown of a construction of a pipe stem smoke regulator which will produce the desired objects outlined above, and which when placed on the outside or inside of the stem will at the same time through its lnterlocklng'means interlock itself securely in place on or in the bite end of the stem.

In the device illustrated in the drawing, the pipe is divided into a bowl portion 2 and a stem portion 3. Positioned at the bite end of the stem portion on the outside thereof is a bead or flange 5. Throughout the stem portion is a passage or bore 6 which communicates with the bowl of the pipe as shown. The pipe may be of integral or composite structure. Positioned on or in the end portion of the stem portion and integral or otherwise with, is a smoke regulator means 1. It will be observed that the shape of the regulator is such as to encompass the stem snugly when used on the outside, and to fit snugly therein when positioned on the inside. On the regulator may be formed a bead means 8, the purpose of which is tostrengthen the regulator at that point. The regulator has an internal recess 9 which cooperates with and snugly fits and interlocks with the beadi on the pipe stem. Provided in the regulator is a mixing or air chamber l from which is an egress or aperture H, and a frusto conical or other suitably shaped ingress l2; The open end I! of the regulator is restricted in such a manner as to form an air tight and moisture tight joint between the pipe stem and the regulator. The frusto conical or other suitably shaped ingress l2 in the regulator is an air inlet and is positioned below the egress II. The egress may be of any suitable shape or size, or maybe foraminous, and is positioned in the top side of the chamber of the plane to another.

When a regulator 20 is used to fit into the end of a pipe stem I 9, the stem is equipped with an internal bead means II for the purpose of interlocking with the groove I! in the regulator. when the regulator 22 is integral with a pipe stem 2|, the pipe stem is provided with a band 23. The band 23 may be eliminated as shown in Figure 5 or it may be inserted therein as shown at 24 in Figure 6. The, regulator may be constructed with an integral end wall 25 to provide a chamber 26, and the bite end of the stem is provided with av cap 21 having an internal head 28 which interlocks in a groove 29 on the stem to hold the cap in place. The cap is provided with the usual egress and ingress openings.

thirdly, to permit moisture and air in the oral cavity to mix with the smoke before the smoke enters the mouth of a smoker; and fourthly, to increase the length of the smoke travel by changing the direction of the smoke from one 40* The operation of the device is as follows. The unit is stretched over or inserted in the end of the pipe stem and fixed to place. The smoke is then drawn from the bowl .to the mixing chain-A5 ber,from which it later travels in an upward direction through an egress into the-mouth or the smoker. When the smoke enters the mixing chamber or expansion chamber it is turned from its original direction at an angle of ap- 5 proximately 90 degrees therefrom. After leavingthe mixing chamber it then travels upward through the egress into the oral cavity of the smoker, and instead of hitting or striking the I tongue first, it strikes against. the palate or the As the smoke leaves the end of a pipestem it is travelling at a high velocity into the mixing chamber. In the mixing chamber it ex-' pands and rotates centripetally therein; such ex-" pansion and rotating causing the moisture and air in the mouthto enter through the small in-- gress into the mixing chamber where it becomes mixed with the smoke. Such mixing causes the temperature of the smoke toqdrop, so that on leaving the mixing chamber it travels through the large egress to strike the palate instead of the tongue. As the smoke leaves the egress it again expands into a large cavity or oral cavity, which expansion reduces the temperature and pressure, thus rendering the smoke non-irritatv .ing to the mucous membrane lining the oral cav-' in the mixing chamber, much of the nicotine contained therein is thrown therefrom, and leaves the mixing chamber by bleeding from the small ingress in the bottom side of the device.

As the smoke travels from the mixing chamber into the mouth, it is constricted as it flowsthrough the large egress. This constricting or squeezing of the moisture laden causes moist air from the oral cavity to be sucked or drawn through the ingress and then into the hot or warm smoke where it thoroughly mixes.

Any saliva or nicotine which might find its way into the mixing chamber may drain through the ingress in the bottom of the device into the mouth of the smoker, from which it may be eliminated. In this manner the device tends to prevent the saliva and nicotine from being forced back into the pipe stem as is now found in the ordinary smoking pipe.

Again as the smoke expands in the mixing chamber, and as it passes through the egress it has a tendency to force the saliva away from the egress thuspreventing its entry into the chamber from that point. The expansion of the smoke in the chamber will also prevent the saliva from entering into the small ingress. In order that this invention will function according as herein written it is to be understood that the ingress is extremely small in cross section when compared smoke through the egress with the egress in cross section. By having the egress very large in cross section compared with the ingress cross section, the smoke as it passes I through the stem into the expansion chamber of the unit will on its expansion therein draw or suck moisture from a smokers mouth into the chamber, and while this process is going on the moisture laden smoke flows from the large egress into the mouth of a smoker.

While I have herein shown and described a preferred arrangement, it will be readily understood that changes and modifications therein may be found desirable or essential in meeting the various exigencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifications as may be found desirable or essential in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claim when broadly construed.

What I claim is: I

In a smoke regulator for pipes and the like, com-- prising, a chambered portion; a chamber therein; a smoke egressin the upper portion of the chambered portion; an air ingress in the lower portion of the chambered portion, and substantially below the smoke egress; and a stem attaching portion integral with the chambered portion.
