Description

D 1955 J. P. PARKINSON SMOKER S PIPE Filed June 19, 1953 s R v, WW m M X 4 w p M f. M 0 d w y United States Patent O SMOKERS PIPE John P. Parkinson, Detroit, Mich. Application June 19, 1953, Serial No. 362,754 1 Claim. (Cl. 131-195 This invention relates to smokers pipes, and more particularly, has reference to a bowl formation for a smokers pipe wherein the recess of the bowl is bounded by a plurality of slots, said slots being disposed nearly tangentially of the recess and opening at their ends upon the outer surface of the bowl.
Among important objects of the invention are to provide a pipe which will be cool to the touch; will be light in weight; will be capable of manufacture in any of various shapes or sizes without losing the advantages of the invention; will be easy to manufacture; and adapted for conversion from a conventional pipe.
Other objects will appear from the following description, the claim appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:
Figure 1 is a top plan view;
Figure 2 is a side elevational view;
Figure 3 is a transverse sectional view through the bowl on line 3-3 of Figure 2; and
Figure 4 is a longitudinal section through the bowl on line 44 of Figure 2.
In accordance with the present invention, the bowl of the smokers pipe has a center recess 12 which can be lined as at 14. The bowl can be made of briar or any other conventional materials, and can have a wall thickness no greater than that of a conventional pipe not having the inventive structure to be described hereinafter. Further, the recess is of conventional depth and width. All these factors are believed to be of importance, since it is a worthwhile characteristic of the invention that the structure thereof permits the cooling means to be embodied in previously manufactured, conventional pipes, through a simple conversion process.
In accordance with the present invention, a pair of diametrically opposite slots 16 are formed in the bowl wall, at opposite sides of the recess 12, said slots extending longitudinally of the pipe. Further, in accordance with the invention, a pair of diametrically opposite transverse slots 18 are formed in the bowl wall, the slots 18 extending transversely of the pipe, and intersecting at their ends with the ends of the slots 16, the several slots opening upon the outer surface of the bowl wall through slot-like apertures 20, the slot-like apertures being disposed at the points of intersection.
At will be noted, the slots 16 and 18 lie in planes nearly tangential to the recess 12, the mid-length portions of the slots being very close to the recess, and being separated from the interior of the recess by a very thin wall portion. As a result, heat transfer through the very thin wall portion is facilitated, the heat being transferred into the mid-length portions of the slots, and being then drawn out of the slots through the medium of air circulating freely through the slots from the ends thereof.
The pipe illustrated has a conventional stem 22 and mouth piece 24, these parts being of ordinary design and not constituting, per se, parts of the present invention.
The particular construction illustrated and described of the recess of the bowl (Figure 4).
provides a bowl which will be cool to the touch, so as to prevent one from burning his fingers when grasping the bowl. Further, a cooler smoke will be another desirable result of the construction, due to the fact. that the transfer of heat from the interior of the bowl is accelerated measurably, due to the nearly tangential arrangement of the slots, and the opening of the slots at their ends upon the outer surface of the bowl.
It is also important to note that the top and bottom portions 25 and 27, respectively, of the slots, between the open ends thereof, terminate close to the top and bottom ends respectively of the recess (see Figure 4), so as to leave the bowl wall unslotted at the opposite ends of the recess. Y
With further reference to the particular formation and relative arrangement of the slots, as will be noted in Figure 3 the slots 16 lie in planes paralleling the longitudinal center line of the stem, while the slots 18 lie in planes normal to the planes of slots'16. Further, the planes of the slots 16, 18 are disposed in parallelism with the axis Still further, the outer side walls Thus, the slots particular arrangement of the inner and of the respective slots is of importance. 16 have outer side-walls 26 closely spaced from and paralleling the inner side walls 28 of said slots 16, while the slots 18 have outer side walls 30 similarly arranged relative to the inner side walls 32 of the slots 18. The inner side walls 28 intersect with the inner side walls 32 at points occurring substantially at the outer circumference of the bowl, while the outer side walls 26 of slots 16 have their ends terminating upon said outer bowl circumference at points spaced circumferentially of the bowl from the ends of the outer side walls 30 of the slots 18. This arrangement, as will be apparent from Figure 3, causes the several slots to define a narrow, continuous rectangular passage extending about the full circumference of the recess of the bowl, with said passage extending over the greatest part of the length of the recess as shown in Figure 4, that is, the top and bottom portions of the passage are close to the outer and inner ends, respectively, of the recess. The passage, as shown in Figure 3, is formed with corner openings due to the particular formation and relative arrangement of the slots previously described herein, said corner openings being the slot-like apertures 20. Each aperture is of a width, due to the mentioned arrangement of the inner and outer side walls of the slots relatives to the outer circumference of the bowl, substantially equal to the combined widths of the intersecting slots that form said apertures. The apertures, further, are angularly spaced ninety degrees apart about the bowl circumference, and because of the specified arrangement of the several slots relative to the longitudinal center line of the stem, when the bowl is gripped in a natural manner between the thumb and forefinger at opposite sides of the bowl, the finger and thumb will not cover any of the apertures, and further, will be in contact with the bowl where there are substantially thick wall portions, to provide maximum coolness to the touch.
A decidedly important characteristic of the invention resides in the adaptability thereof to previously manufactured pipes not having the slotted wall formation in the bowls thereof. In other words, a wholly conventional pipe can be converted, through the medium of ordinary tools such as slotting drills, or conventional drills and saws. It is merely necessary that each slot be formed in turn, and on completion of the formation of the several slots, said slots will all open at their ends upon the outer surface of the bowl wall, at the points upon the bowl wall outer surface where the tools were entered.
It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may he-suited. Noris the invention to be necessar ly limi d to the specifi c nst u t i r e n described, since such construction is only intended to be illustrative of the principles (of operation and the means presently devised to carry out ,said principles, it being considered that the invention comprehends any minor change in construct-ion that may be permitted within the scope of the appendedclaim.
What is'claimed is:
In a smokers pipe having a stem, a bowl of circular cross sectionon one end of the stern and having a central tobacco-receiving recess also of circular cross section, the bowl being formed with a first pair of diametrically opposite, narrow slots lying in planes extending longitudinally-of the pipe .in parallelism with the longitudinal center line :of the stern and with a second pair of diametrically opposite, narrow slots lying in planes extending normally to the planes of the first slots, the several planes of the slots being nearly tangential to said recess in parallelism ,with the axis of the recess, the top and bottom portions of the slots being spaced inwardly from the top and bottom ends, respectively, of the bowl to leave the bowl wall unslotted at the outer and innerends of the recess and being closely spaced from said outer and inner ends, respectively, of the recess, the slots of each pair intersecting at their ends with the ends of the other pair and opening at the points of intersection upon the outer surface of the bowl for free circulation of cooling air therebetween, the several slots defining a narrow rectangular passage extending continuously about the recess over the greatest part of the length of the recess and opening at its corners upon the outer surface of the bowl, the slots of each pair having inner side walls intersecting with the inner side walls of the slots of the other pair at points occurring substantially at the outer circumference of the bowl, and having outer side walls the ends of which terminate upon said outer circumference at points spaced circumferentially of the References Cited in the file of this patent UNITED STATES PATENTS 986,024 Odenbaugh et al Mar. 7, 1911 2,251,545 Munzer Aug. 5, 1941 2,481,971 Beeneck Sept. 13, 1949 2,651,307 Ferguson Sept. 8, 1953 FOREIGN PATENTS 561,722.
