vUNITED STATES PATENT OFFICE 2,588,713 SMOKING PIPE Alexander A. Fischbach, St. Paul, Minn.

Application April 1, 1946, Serial No. 658,829

1 Claim.

This invention relates to new and useful improvements and structural refinements in smoking pipes, and the principal object of the invention is to provide a device of the character herein described, which is particularly adapted to prevent the passage of nicotine and other impurities from the pipe bowl to the mouth of the smoker.

A further object of the invention is to provide a pipe which may be readily disassembled for purposes of cleaning, inspection or repair.

Another object of the invention is to provide a pipe which is of simple construction and Whic cannot easily become damaged.

With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the invention;

Figure 2 is a cross sectional view, the same showing the filtering chamber and being taken approximately along the longitudinal center line of the pipe stem;

Figure 3 is a side elevation of the cover plug and adapter used in the invention;

Figure 4 is a top plan view of the subject shown in Figure 3;

Figure 5 is an underside plan view showing a portion of the stem, and

Figure 6 is a cross sectional view of the cover plug and adapter with the baflie plate in situ thereon.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention consists of a pipe comprising the conventional bowl and shank portion Ill and a stem portion II, the same being separably connected together by the usual adapter I2. A downwardly projecting extension I3 is provided on the portion II, the same being of a substantially tubular configuration and forming the filtering chamber I4.

The stem portion II is formed with the usual smoke passages I5 and I6, the latter communicating with a further smoke passage (not shown) in the portion II]. It will be noted that the passages I5 and I6 enter the chamber I4 at the relatively opposed sides of the same.

A cover plug ll, provided with a knurled surface portion I8, is positioned at the lower end of the extension I3, this plug also being provided with an integral adapter I9. The latter is of a tubular configuration and slidably extends into the chamber I4, as will be clearly apparent from the accompanying drawings.

The adapter I9 is formed in the bore thereof with a pair of diametrically opposed slots 20, the same extending partially along its length, from its upper edge 2 I.

A bafiie plate 22 is provided with the stepped edges as indicated at 23 and 24, whereby it is adapted for removable positioning in the slots 20 of the adapter I9, as will be clearly understood from the accompanying Figure 6. It may be added in this connection that the steps 23 engage the upper edge 2| of the adapter and the steps 24 are disposed adjacent the lower end of the slots 20.

When the invention is placed in use, the baiile plate 22 is positioned on the adapter I9 as already set forth, and the latter, together with the associated plug I1 is applied to the chamber I4, as-

is best shown in Figure 2. It will be noted that the upper end of the bafile plate 22 extends intermediately of the passages I5, I6 and the smoke from the bowl will travel in the direction of the arrows 25 through the filter chamber, as will be readily understood.

The nicotine and other impurities from the bowl will thus be collected in the lower end of the adapter I9 and may be easily cleaned therefrom by simply removing the plug I! and the associated adapter from the chamber I4.

It is believed that in view of the foregoing, the I operation and use of the invention will be readily understood, and further explanation thereof at this point is therefore considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

A smoking pipe comprising in combination, a bowl and shank portion and astem portion separably connected thereto, a downwardly projecting extension on said stem portion defining a cylindrical filtering chamber, said portions being formed with smoke passages communicating with said chamber at the relatively opposite sides thereof, a removable cover plug at the lower end of said extension, a tubular adapter on said plug, said plug and tubular adapter forming a trap for liquified nicotine and nicotine burdened moisture, said adapter being formed with a pair of diamet- 3 rically opposed slots in the bore thereof, and a bafile plate having stepped edges and shoulders and removably positioned in said slots and extending intermediately of said passages, certain of said shoulders engaging the top of said tubular adapter, whereby the bafiie is easily removed from said extension along with said adapter and the bafile is easily subsequently removed from the adapter in cleaning the pipe.
