Application May 9, 1947, Serial No. 746,984

1 Claim. 1

This invention relates to new and useful improvements in smokers appliances and more particularly and specifically to a pipe attachment of which the following is a specification.

The primary object of this invention resides in the provision of a liner insert for a pipe which extends from the bowl bottom throughout the length of the stem, and which keeps the bowl and stem dry and clean at all times preventing the undesirable clogged and soggy formation which forms inherently in the smoking pipes now in use.

Another object of this invention lies in the provision of such a pipe liner which is quickly and easily removable from a pipe to allow the replacement thereof with a clean and new liner, thereby maintaining the bowl bottom and stem in a clean dry condition and eliminating the necessity of frequently cleaning the pipe and thus keeping the bowl wall formations in the pipe which are desirable but which are necessarily removed when a pipe is cleaned.

Still another object of this invention is the provision of such a pipe attachment or accessory as described which is of an extremely simple and inexpensive design and which is cheap of manufacture.

Still further improvements and advantages will readily appear to those skilled in the art when the following description is read in the light of the accompanying drawings in which:

Fig. 1 is a top plan view of the improved pipe.

Fig. 2 is a vertical section taken on line 2-2.

Fig. 3 is a vertical section taken on line 3-3.

Referring now to the accompanying drawings which illustrate the preferred embodiment of this invention A designates a smokers pipe comprising the conventional elongated hollow stem 1 and an integrally formed bowl 2 opening into said stem from the bottom thereof.

The bowl 2 is provided with a tobacco receiving chamber formed with a recess 3 in the bottom thereof, the recess 3 being rectangular in transverse cross section below the chamber, said recess extending through the wall of the bowl.

An elongated, tapered, hollow tube B of rectangular cross section is inserted through the recess 3 and extends beneath the bowl bottom throughout the length of the recess, the portion of the hollow tube disposed in the recess 3 having its upper surface flush with the bottom of the tobacco receiving chamber, where it is formed with a plurality of openings 6 which establish communication between the tobacco receiving chamber and tube. As shown, the tube extends through the recess a substantial distance beyond the outer surface of the bowl 2. The small end of the tube B is open at 4 adjacent to the mouthpiece C of the stem so that smoke may be 2 drawn therethrough, while the larger end 5 of the tube is closed.

Thus it may be seen that a complete liner has been provided for the pipe stem which separates the stem from the bowl thus preventing the formation of soggy accumulation in the stem, but will permit the passage of smoke thereinto through the restricted openings 6.

When it is desirable to remove the liner tube B the extended end 5 thereof is grasped and the liner pulled completely free of the remaining parts of the pipe, and a new liner may then be inserted thus maintaining a dry clean stem without necessitating any cleaning of the pipe.

I wish it to be understood that I contemplate any modifications of the illustrated invention such as size, materials used, and general characteristics which fall within the scope of the appended claim.

Having thus described the construction and function of this invention what I desire to claim in Letters Patent is:

In a smoking pipe, a pipe bowl defining a bowl chamber, a pipe stem having a passageway formed longitudinally through the center thereof, formed integral with the bowl, said bowl having a recess rectangular in transverse cross section formed in the bottom of the bowl below the bottom of the bowl chamber, and providing a continuation of the passageway of the stem, a tubular member rectangular in transverse cross section providing a wide fiat upper surface, fitted within the recess of the bowl and in the passageway of the pipe stem, the upper surface of said tubular member within the bowl being flush with the surface defining the bottom of the bowl chamber, the wide flat upper surface of the tubular member having rows of openings therein. through which smoke is drawn into the tubular member from the bowl chamber.
