ALUMINUM SMOKING PIPE Filed March 2o, 1957- INVENTOR. FRED SULZER Y,United States ALUMINUM SMOKING PIPE Fred Sulzer, Brooklyn, N.Y.

Application March 20, 1957, Serial No. 647,251

1 Claim. (Cl. 131-220) This invention relates to a smokers pipe, and has as some of its important objects the following:

To provide a thin aluminum sheeting on the bowl of a smokers pipe, designed to maintain the same cool to the touch While at the same time affecting heat transfer properties to a minimum extent;

To form said sheeting in a manner such as to cause the same to occupy a minimum amount of space on the bowl, so as to leave a substantial amount of space for the briar or similar material found desirable in bowl construction;

To arrange the aluminum covering in such a way as to provide an attractively nished pipe; and

To provide an aluminum covering as described which will not add cost to the pipe except, perhaps, to a very slight degree.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective View of a smokers pipe incorporating the invention.

Fig. 2 is an enlarged sectional view on line 2-2 of Fig. 1.

Fig. 3 is an enlarged sectional view similar to Fig. 2 showing a modified construction.

Fig. 4 is a transverse sectional view on an enlarged scale, on line 4-4 of Fig. 1.

Fig. 5 is a partially exploded perspective view of another modification.

Fig. 6 is an enlarged sectional view on line 6-6 of Fig. 5, in which the parts are in their nally assembled relation.

Fig. 7 is an enlarged transverse section on line 7-7 of Fig. 5.

Referring to the drawings in detail, in Figs. l, 2 and 4 a pipe generally designated 10 includes a stem 12 of briar or similar material to which is connectable a mouthpiece 14. Stem 12 is integral with a bowl 16 having a tapering tobacco recess 18 communicating at its lower end with the bore 20 of stem 12. Uniformly spaced about the circumference of recess 18 are deep, small diameter recesses 22, metal lined as at 24, designed to provide air spaces for cooling the bowl at its upper end.

In accordance with the invention, a thin sheet 26 of aluminum coats the entire surface area of the stem 12 and bowl 16. The thickness of the sheet has been exaggerated somewhat in Figs. 2 and 4. However, in practice the sheet would be very thin, being in fact a flexible foil which is molded to the desired shape about the bowl and stem. It has been found that this provides a highly desirable, novel addition to the pipe construction, cooperating wtih the particular formation illustrated to best advantage in Fig. 2, by providing a surface of f 'i ICC lbowl. This is accomplished throughthe doctrine of reflection. The heat waves reaching the sheet 26 are reflected away therefrom.

In Fig. 3 the construction is modified only to the extent of eliminating the recesses 22. Thus, the bowl 16a has a tobacco recess 18n communicating with bore 20. The aluminum covering 26 is identical to the rst form and the recesses 22 are omitted.

In Figs. 5-7, the modied pipe 10b includes a stem 12b to which is detachably connectable, in any suitable manner, mouthpiece 14". Stem 12b is integral with bowl 16", and both the stem and the bowl can be made of briar or other well known pipe bowl material.

Formed in the portion 16b of the bowl is a recess tapering inwardly along curving lines and designated at 28. This receives an insert 30 constituting an upper portion of the bowl, which is frictionally, snugly engaged in the recess 28 and has a thick circumferential collar 32 at its upper end. Formed in the upper portion 30 of the bowl is a tobacco recess 18b communicating at its inner end with a bore 20b which extends continuously through the insert 30 and the portion 16b of the bowl.

Cemented or otherwise xedly secured to the underside of the collar 32 is an annular spacer 36 of cork or similar material, which has been found to produce valuable heat insulation characteristics,v designed to reduce heat transfer from the portion 16h to the collar 32, to the minimum extent. The cork 36 is disposed im mediately above the top edge of an aluminum covering 26b of the pipe, which completely covers the bowl portion 16b and the stem 12b.

In other words, the covering 26b makes the pipe bowl cool to the touch, should one attempt to grasp the portion 16h. Any heat that might tend to pass upwardly from the portion 16b is retarded by the cork layer 36, which cooperates with the coating 26b in providing a pipe bowl that is cool to the touch, since the layer 36 tends to prevent heat transfer to the collar 32 which is not covered by the aluminum.

All forms of the invention utilize a very thin aluminum covering, in intimate, fully covering relation to the bowl of the pipe, for the purposes previously described herein.

It is to be understood that any suitable insulating material may be inserted between the briar or other well known pipe material and the aluminum covering for maintaining the bowl which is cool to the touch.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as delined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

A smokers pipe comprising a stern, a mouthpiece on the stem, a bowl connected to the stem, said stem, mouthpiece and bowl having aligned smoke passages, and a thin metallic sheath for the bowl, said bowl comprising a thick-walled lower bowl portion, and a thickwalled upper bowl portion removably engageable in the lower bowl portion and having a tobacco recess, the sheath covering only the lower bowl portion, said bowl further including an annular, a cork spacer between the upper and lower bowl portions, the sheath extending upwardly along the lower bowl portion to the spacer, said upper bowl portion having at its upper end an outwardly directed, thick collar defining a downwardly i 3 Y facing circum fe reritia1-` shoulder, the spacer being xedly 1,828,149 secured to the shoulder. 2,226,707
