Description

Oct. 28, 1969 w.; H. JONES E AL SMOKING PIPE Filed April 4, 1966 INVENTORS WILL/.5 H. JONES W/LLJS D- JONES A TTORAIEY United States Patent Ofice 3,474,793 Patented Oct. 28, 1969 vs. Cl. 131-195 7 Claims ABSTRACT on THE DISCLOSURE A tobacco pipe having an outer bowl with a horizontal bore extending entirely therethrough and traversing the vertically arranged bore in said outer bowl is seated in the verticalbore of the outer bowl so that substantial portions of the side wall of the inner bowl are exposed at the intersection with the horizontal bore, the latter forming air chambers at opposite sides of the inner bowl, together with vertical venting bores which extend entirely through the wall of the outer bowl and intersect the air chambers formed by the horizontal bore, the outer ends of the horizontal bore being closed by perforated discs.
- This invention relates to a smoking pipe and in particular to an improved pipe bowl construction having an in- The exterior surfaces of uninsulated pipe bowls become quite hot and pipe smokers oftentimes cannot grip the bowl of the pipe due to the intensity of the heat conducted to such exterior bowl surfaces. Bowl constructions which insulate the tobacco burning recess from the exterior surfaces thereof are known but mainly entail circuitous and complicted vent passages which necessitate expensive bowl constructions and manufacturing techniques. Ideally, the vent passages should be arranged to provide efficient insulation and cooling, yet allow simple and inexpensive fabrication of the pipe bowl.
Accordingly, it is an object of the present invention to provide a pipe having a tobacco carrying pipe bowl wherein heat from the burning tobacco is substantially dissipated by air circulation through generally annular spaces between an inner tobacco bowl and an outer housing portion, leaving the exterior surfaces of the outer housing portion relatively cool.
It is an object of the present invention to provide a pipe including an outer housing supporting an inner tobacco carrying bowl together with cooling passages through the outer housing and between the housing and the inner bowl for conducting heat which radiates from the hot inner bowl to the ambient atmosphere, leaving the exterior surfaces of the outer housing portion largely unaflected there- It is another object of the present invention to provide a pipe including a pipe bowl structure having the foregoing characteristics which is simply and easily fabricated.
Various other novel features of construction and advantages inherent in the smoking pipe construction of the present invention are pointed out in detail in conjunction with the following description and the accompanying drawing of a typical embodiment of the present invention.
In the drawing:
FIG. 1 is a general side elevational view of one form of the smoking pipe of the present invention;
FIG. 2 is a fragmentary vertical cross sectional view taken lengthwise through the pipe of FIG. 1;
FIG. 3 is a fragmentary top plan view of the pipe construction of FIGS. 1 and 2; and
FIG. 4 is a transverse cross sectional view taken about on the line IV-IV of FIG. 3.
Referring now to the drawing and in particular FIG. 1, there is shown a tobacco pipe having a stummel generally designated 10 including the usual bowl 11 and shank 12 together with a tubular axially bored stem 13 and a mouthpiece 14. Mouthpiece 14 has the usual smoke passage 15 opening through opposite ends thereof together with an extension 16 at one end which threads into the upper bored end of stem 13. A tongue 17 projects axially from the threaded extension 16 within the bore of stem 13 in a well-known manner. Stem 13 has a reduced diameter lower portion which seats snugly in an inclined socket 18 in shank 12. In the illustrated instance a collar 19 spaces the body portion of stem 13 from the adjacent face of the shank.
Bowl 11, in the preferred form, is of the usual woods employed in pipe bowl construction, although other materials may be employed. Bowl 11 is generally square as viewed in plan and has a V-shaped lower portion as viewed from the sides. This V-shaped lower portion provides two flat surfaces and the pipe may rest on either of these surfaces in a stable manner with the stem extending either horizontally or vertically. In cases where the stem extends at the angle shown in the drawing, the pipe would rest at the line forming the apex of the dihedral angle formed by said sides, and the right end portion of the mouthpiece 14 as illustrated, due to the curvature thereof. Bowl 11 has a generally cylindrical chamber 21 opening through its top face terminating at its lower end in a conical seat. A passage 22 extends from chamber 21 to socket 18 and is coaxial with the latter.
A transverse bore 24 extends through bowl 11. Bore 24 is preferably circular to facilitate formation thereof. Enlarged diameter portions 26 are formed in the side faces of bowl 11 to provide seats for receiving discs 27. Discs 27 may be pressed into the seats and may curve outwardly as shown in FIG. 4 to provide additional venting and insulating space. Discs 27 are preferably perforated to provide additional vent holes for bore 24 although solid discs may be used. As shown also in FIG. 4, the discs 27 have short skirts or flanges adapted to bear against the walls of the enlarged portions 26, the flanges having notches spaced around the peripheries thereof.
Four drilled holes 29 extend vertically through bowl 11 adjacent the corners thereof. Intermediate portions of holes 29 open into transverse bore 24 as at 30 in FIG. 4.
A generally cylindrical tobacco bowl 32 with a conical lower end 33 fits snugly within chamber 21. The lower conical end 33 of bowl 32 seats in the aforesaid conical seat at the lower end of chamber 21 of bowl 11 and the upper side wall portions of bowl 32 are exposed to bore 24 at opposite sides. Insertion of bowl 32 into chamber 21 divides bore 24 and forms a separate air chamber at each side of bowl 32 within outer bowl 11, each such chamber being defined by a disc 27, interior wall portions of bore 24 and exterior wall portions of 'bowl 32. Each air chamber is vented through the top and bottom faces of bowl 11 by upper and lower portions of the holes 29, with additional venting being provided by use of a perforated disc 27. A passage 35 in inner bowl 32 which is coaxial with passage 22 of outer bowl 11 and shank 12 extends between a reduced cavity 36 at the bottom of the interior of bowl 32 and passage 22, thereby completing the smoke passage. When tobacco is pressed into the bowl in the usual manner it will naturally pack less tightly in the reduced cavity 36, thus facilitating the drawing of smoke through this reduced cavity and also reducing the likelihood of clogging.
The cavities on opposite sides of inner bowl 32 provide direct cooling to such inner bowl. Air enters through the lower portions of holes 29 and passes directly into the cavities, and circulates about the sides of bowl 32 in heat exchange relation therewith. The heated air then vents through the upper portions of holes 29, thereby creating a draft which continuously circulates air through the cavities. Where additional cooling is desired, perforated discs are utilized in lieu of solid discs at the sides of the bowl structure, thus causing additional air circulation within the cavities and hence additional cooling of bowl 32.
In the rest positions described earlier herein the inclination of the bowl is such that ashes will not tend to spill therefrom and in the vertical position condensation in the stem and in the passage will tend to return to the reduced bowl cavity 36.
We have thus fulfilled the objects of our invention in providing a pipe having a pipe bowl which is easily and readily fabricated and in which the exterior surfaces thereof remain largely unaffected by and insulated from the heat of the burning tobacco. Having thus described and illustrated a preferred embodiment of our invention, it is to be understood that such embodiment is by way of example only and to illustrate the principles of the present invention.
We claim:
1. A tobacco pipe comprising an outer bowl having side walls and top and bottom faces together with a central chamber which opens through said top face, said outer bowl having a lateral passage intersecting said central chamber and opening through said side walls, an inner tobacco receiving bowl seated in said chamber and intersecting said lateral passage whereby said lateral passage forms a pair of air chambers at opposite sides of said inner bowl, closure members secured adjacent said side walls at the outer ends of said lateral passage to define said air chambers, venting passages through said outer bowl to said air chambers for circulating air within said chambers adjacent said inner bowl, a pipe stem connected to said outer bowl, and passage .means providing smoke communication between said inner bowl and said stem.
