2 Claims.
This invention relates to tobacco smoking pipes.
The primary object of the invention is to provide the smoker thereof with a dry, cool, and full flavored smoke without biting the tongue and without a strong taste in the mouth.
A further object of the invention resides in the provision of a pipe, so designed, as to be provided with a separable bowl, the lower member of which bowl is provided with a stem and a mouth piece.
-A further object of the invention resides in the provision of a pipe having an inverted cup shaped smoke and fresh air mixing chamber below a tobacco cavity which communicates with the tobacco cavity, and an annular circulating chamber which has communication with the smoke and fresh air mixing chamber.
A further object of the invention characterized is to provide a pipe wherein an admixture of smoke and air into a mixing chamber at opposite ends thereof will be drawn into a circulating chamber through a plurality of pairs of passages spaced at different elevations in the front wall portion of the mixing chamber and will then be drawn from the circulating chamber into one end of a bowl stem wall adajacent the top surface thereof at an elevation substantially the same as the highest elevation of the transfer of admixture of smoke and air into the circulating chamber, and at a point diametrically opposite the transfer of the admixture of smoke and air from the mixing chamber into the circulating chamber, and from which bowl stem wall the smoke is drawn through a mouth piece into the mouth of the smoker, providing thereby a dry, cool smoke.
-A further object of the invention resides in providing the outer wall of the mixing chamber with vertically spaced circumferential means for increasing the interior cooling surface area of the circulating chamber directly surrounding the mixing chamber.
The embodiment of the invention herein disclosed is merely illustrative, and may be modified and departed from in various ways without departing from thespirit and scope of the invention, as pointed out hereinafter, and limited solely by the appended claims.
To the attainment of the above stated objects and others which will appear as the nature of the invention is better understood, the invention further resides in the novel features of construction, combination and association of parts, a practical embodiment of which is disclosed by the accompanying drawings:
Referring to the drawings:
Fig. 1 is a top plan view of the pipe.
Fig. 2 is a front elevation of the pipe.
Fig. 3 is a longitudinal vertical section of the pipe embodying the features of the invention.
Fig. 4 is a top plan view of the lower pipe bowl member.
Fig. 5 is a longitudinal vertical section of the lower pipe bowl member.
Fig. 6 is a front elevation of the top and interior bowl member with a portion thereof in cross-section.
Fig. 7 is a bottom plan view of the top and interior bowl member.
Referring to the pipe structure, we employ a lower bowl member, an upper and internal bowl member which is removable from the lower bowl member, and a mouth piece which is removable from a stem integral with the lower bowl member.
In carrying the invention in practice, the lower bowl member comprises a bowl portion I having a central bore 2 and a counter-bore 3, thus leaving the bowl portion open at the top which pro-- vides a relatively thin side wall 4 and a relatively thin bottom wall 5, which bottom wall has a flat bottom face 6. The axis of the bore 2 is a few degrees less than a right angle to the plane of the lower fiat face 6 to allow nicotine to flow toward the front of the pipe.
A straight horizontal stem portion 1 projects y from one side of the bowl portion I with the lower face substantially in a plane with the lower flat face 6 of the bowl portion I so that the pipe can rest on a flat surface with the bowl in an approximately upright position and without danger of the pipe tipping over; The stem portion I is provided with a longitudinal bore 8 to within a short distance of the bore 2 in the bowl portion l to provide a partition, or wall 9 of a relatively greater thickness than the bowl wall 4, between the inner end of the bore 8 and" the bore 2. The bore 8 is of a diameter substantially equal to the height of the bore 2 in the bowl portion l, and the wall, or partition 9 is provided with a straight horizontally disposed smoke passage 0 which communicates at its inner end with the juncture of the bore 2 and counter-bore 3 and at its outer end with the inner end of the stem bore 8 closely adjacent the upper face of the bore 8.
The mouth piece designated II is provided at its outer end with a suitable bit I2 and at "its inner end with a stem portion [3 of a diameter to provide a snug slip fit in the outer end portion of the stem bore 8, and the stem portion of the mouth piece is of such length as to provide an 3 elongated horizontally disposed well I4 between the inner end of the mouth piece stem I3 and the bowl Wall 9.
The counter-bore 3 provides a juncture with the bore 2 of the bowl portion I substantially in a line with the upper side of the bore 8, and the wall of the counter-bore 3 is straight, as at for a short distance from the upper edge of the bowl portion l and then it is curved, as at is, and converges to form a juncture with the upper end of the straight walled bore 5, as clearly shown in Fig. 5.
The bottom wall 5' of the bowl portion I is provided centrally of the bore 2 with an upstanding stem or boss I1 having a very small diameter opening II arranged centrally'thereof and open to the lower face 6 of the bowl portion I and to the inner end face of the stem I1.
The removable top and internal bowl member of the pipe comprises a top bowl portion I8, a
lower bowl portion I9 and an intermediate bowl portion 20.
The top bowl portion i8 is provided with a shoulder 2| adjacent the upper end of the intermediate bowl portion and the top bowl portion at the shoulder 2I is of the same outside diameter as the upper edge portion of the lower pipe bowl member I, so that the outer side face of the upper bowl portion I8 will lie flush with the upper edge portion of the lower pipe bowl portion 4 when the parts are assembled and polished. When assembled, the pipe bowl has a gentle outwardly curved appearance, as will be apparent from Figs. 2 and 3, and the shoulder 2| of the top and internal bowl portion will lie flush with the upper face, or edge of the lower bowl portion I to provide a tight joint therebetween. The intermediate bowl portion 20 is of slightly less outside diameter than the inside diameter of the lower bowl portion I at its upper end portion, and the intermediate portion 20 a short distance from the shoulder 2! is provided with a fiat ring of cork, or equivalent material 22 which is seated in a facial groove 23 in the outer wall of the intermediate bowl section 26 so as to frictionally grip the wall of the counterbore 3 to hold the top and internal bowl member against accidental upward, or rotary displacement in assembly with the lower bowl portion I, yet freely removable when desired by a slight rotary and upwardly pull.
The intermediate bowl portion 20 is convexed, or curved outwardly from the lower edge of the cork ring or band 22 and converged to meet with the upper end of the lower bowl portion I9. The lower bowl portion of the upper and internal bowl member has a diameter less than the diameter of the bore 2 of the lower bowl member I so as to provide a circulating chamber 24 surrounding the bowl portion I9 and which chamber communicates at its upper end with the lower end of a circulating chamber 25, which surrounds the intermediate bowl portion 20 below the cork band 22, and which chamber 25 gradually widens toward its lower end. The outer face of the lower bowl portion I9 is provided with a plurality of suitably shaped grooves 25 spaced one above the other-to provide a greater smoke cooling surface area for the circulating chamber 24 communicating with the non-groove circulating chamber 25.
The top and the bottom portions IS and i9, respectively, of the removable bowl member is provided with a suitabletobacco receiving cham ber 21 communicating through a metal tube 28 4 is positioned in an opening 29 with a suitable smoke and fresh air receiving and mixing chamber 30 open to the lower face of the cavity 30, which provides for the lower portion IS a side wall with a flat lower face 3I, which face, when the two bowl members are assembled, has a slight clearance from the inner face 5 of the bottom wall 5 to provide for expansion, and which clearance space becomes sealed with a tar coating after the pipe has been smoked, and positively separates the chambers 24 and 30.
The wall of the lower bowl portion I9 is provided with a plurality of smoke passages, preferably three horizontal rows thereof, designated, 32, 33 and 34, and preferably two openings in each row. Thus, the row of passages 34 will be at a higher elevation than the paswhich results in a smoke, without moisture being drawn into thesage 32 and the passages 33 will be at a higher elevation than passage 32. The row of passages 34 will be at substantially the same elevation as the smoke outlet passage i9. The smoke passages 32, 33 and 3 1 are of less diameter than the smoke outlet passage ID and are arranged at different elevations so they may be grouped closely together and occupy a small area at the very front side of the wall of the lower cavity 30, thus causing the smoke to travel as far as possible before entering the passage I0.
When smoking the pipe herein described, the smoke from the burning tobacco in chamber 21 passes downwardly into the mixing chamber 30 between the intermediate bowl portion 20 and the inner face of the bottom wall 5 of the lower bowl member I, and there it mixes with a limited amount of fresh air entering the centrally arranged mixing chamber 30 as the smoker draws on the pipe. The mixing of the fresh air through air passage I? with the smoke cools the smoke, and from the mixing chamber 30 the admixture of smoke and fresh air passes through the smoke passages 32, 33 and 34 at three different elevations and enters the circulating chambers 24 and 25 at the front end "of the separable pipe bowl. The smoke is 'thus give-11 a chance to expand and circulate in the communicating chambers 24 and 25 and is finally drawn therefrom at an elevation sub-' stantially with that of the passages 3 through the passage I0 into the stem well I4, and then finally drawn from the well I4 through the mouth piece into the mouth of the pipe smoker, pleasing dry, cool, fragrant mouth and without moisture gurgle in the bowl, and without a bite on the tongue, or a strong taste in the mouth.
It will be clearly apparent that when the smoke is drawn into the well It, that it will again expand and circulate before being drawn through the mouth piece of the pipe.
The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which the invention relates.
What we claim is:
l.
