Dec. 22, 1959 F. e. BORGER SMOKING PIPE Filed Jan. 19, 1956 AT TORNEY SMOKMG PIPE Frank Grosse Borger, Fort Lee, N..I., assignor to Weber Brian's, Ind, Jersey City, N.J., a corporation of New Jersey Application January 19, 1956, Serial No. 560,149

1 Claim. (Cl. 131-225) This invention relates to new and useful improvements in a smoking pipe.

In most of the commercial smoking pipes, the bowl is formed with either an integral stem or with a short extension to which the stem is joined. This necessitates using stock of considerable length and width in order to form the bowl.

It is a prime object of the present invention to provide a smoking pipe with separate bowl and stem portions, the bowl being formed without a stem or stem extension.

Another object of the invention is to provide a smoking pipe with separate bowl and stem portions formed .of briar wood so as to utilize the short blocks and lengths of briar wood in the formation thereof.

A further object of the invention is to provide a smoking pipe with separate bowl and stem portions embodying a novel leakproof joint between said portions without the use of metal parts.

It is further proposed to provide a smoking pipe with separate bowl and stem portions which are readily assembled by a single operation.

It is also an object of the invention to provide a smoking pipe which is simple in construction and which can be manufactured and sold at a reasonable cost.

Other objects and advantages of the invention will be apparent from the description thereof to follow taken in conjunction with the accompanying drawings in which:

Figure 1 is a fragmentary longitudinal vertical sectional view through the center of a smoking pipe made in accordance with the invention.

Figure 2 is a side elevational View of the bowl of the pipe.

Figure 3 is a rear view thereof.

Figure 4 is a bottom plan view thereof.

Figure 5 is a side elevational view of the stem of the pipe.

Figure 6 is a view of the left hand end of the stem shown in Figure 5.

Figure 7 is a top plan view thereof.

Referring to the drawing in detail, a smoking pipe, comprising a bowl 1, a separate stem 2 and a separate bit or mouthpiece 3 is shown in Figure 1. The bowl is readily formed from a small block of briar wood and the stem from a short length of the same material. The bit or mouthpiece may be formed of rubber, rubber composition or plastic or other suitable material.

The bowl 1 comprises the usual substantially cylindri cal upstanding wall 4 enclosing a tobacco chamber 5 and having a bottom portion 6. A smoke passage 7 formed in the bottom portion 6 communicates with the chamher 5.

According to the present invention the bowl 1 has a flat rear surface 8 that is normal to the longitudinal axis of the stem and in which is a dovetail groove 9 that is formed by the undercut side walls 13 which extends from the bottom surface of the bowl toward the top of the bowl and merge into an undercut top wall 2,918,067 Patented Dec. 22, 1959 15 and a surface 12 that lies in a plane normal to the smoke duct 19 on the longitudinal axis of the stem. At the upper end of the flat surface 8 and projecting angularly therefrom is an arcuate wall 11.

The stem 2 is cylindrical in cross-section and is formed with a flat surface 25 at one end and an extension 17 on said end, of dovetail formation and of a shape similar to the groove 9 in the bowl 1. Extension 17 projects centrally and transversely of the flat surface on the end of the stem from the lower side of its periphery and terminates just short of the opposite or upper side thereof, the bottom side 18 of the extension being arcuate in shape and the end 26 of the extension being fiat. An axially disposed smoke passage 1? is formed in the stem and terminates at its rear end in a tapered recess 20 for frictionally receiving and holding the tapered end 21 of the bit or mouthpiece 3 which is provided with the usual axial smoke passage 22.

In assembling the bowl and stem, in a single operation, the dovetail extension 17 on the stem is slid upwardly through the opening in the bottom end of the groove 9 in the surface 8 in the bowl 1 thereby interlocking the slanting side edge surfaces 23 and the top surface 24 of the extension 17 of the stem with the similarly shaped undercut side walls 13 and inner end wall 15 of the groove. When the parts are thus interlocked as shown in Figure l, the flat end surface 25 of the stem 2 which borders the side surfaces 23 and top surface 24 seats on the flat surface and the fiat end surface 26 of the extension 17 seats on the fiat surface 12 of the groove, with the arcuate surface 13 of the extension meeting the bowl surface at the bottom of the bowl, the surface of said end 18 being complemental to the bottom portion 6 of the bowl. The interlocked parts are preferably secured in position by suitable adhesive placed on the abutting surfaces thereof. A sealed, leakproof joint is thus constructed between the bowl and stem of the pipe, without the use of metal parts or auxiliary instruments. The bit or mouthpiece 3 may readily be inserted endwise into the recess 21? in the outer end of the stem 2 and is frictionally held therein as will be understood.

While I have illustrated and described the preferred embodiment of my invention, it will be understood that changes in details thereof might be made without departing from the principle of the invention and I desire to be limited only by the state of the prior art and the appended claim.

What I claim is:

A smoking pipe comprising a bowl and a separate stem connected by a joint between them, wherein said bowl has a fiat rear surface in which is a dovetail groove formed by slanting side walls extending from the bottom surface of the bowl toward the top of the bowl and merging into a slanting top wall, and said separate stem has a dovetail tenon at one end thereof with slanting side and top surfaces bordered by a fiat end surface, with said side, top and flat end surfaces in tight abutting contact with the side walls, and top wall of said recess and said fiat rear surface of the bowl, respectively.
