Application January 5, 1949;,Serial No: 69,297:

I] 1 Claim. l

Myfinvention relates toa'smoking pipe, andA more Vparticularly to improvements over` the subject-"matter of-my former application forl Letters Patent, Serial No. (559;352, led April 3, 1946, now Patent'No. 2,628,622,- issued'February 17, 1953, and the objects -of my invention are:

First, toA prov-ide a'pipe of this class which' is generally rsimplified asV compared to the structure of said formerv patent-application, and which is veryeiiicientfin condensation of'volatile fluids and cooling of thesmoke-passing through the pipe;

Second, toprovide a pipe of this class which is very-simple and easy to yservice Third, to providea-pipe4 of this class having a tobacco lter basket which is very simple and easy to remove# and install when cleaning the DlDe;

Fourth, to provide apipe ofr this class which assumesconventional proportions; and is. substantially equal in weight to conventional smoking pipes;

Fifth, to provide a smoking pipe of this class which greatly protects the health of the smoker by removing harmful nicotine-bearing volatile fluids from the smoke passing into the smokers mouth;

Sixth, to provide a smoking pipe of this class which employs a very simple reverse ow diverter, which considerably lowers the temperature of volatile fluids, permitting the same to be readily condensed and collected in the tobacco contained in the filter basket; and

Seventh, to provide a smoking pipe of this class which is very simple and economical of construction, efcient in operation, and which will not readily deteriorate or get out of order.

With these and other objects in View, as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claim, reference being had to the accompanying drawing and to the characters of reference thereon, forming a part of this application, in which the gure of the drawing is a longitudinal vertical sectional View of a smoking pipe, shown on enlarged scale, and illustrating by arrows the flow of smoke or uid through the pipe.

Similar characters of reference refer to similar parts and portions throughout the drawing.

The bit I, tube 2, basket 3, diverter 4, stem 5 and bowl B constitute the principal parts and portions of my smoking pipe.

The bit I is a substantially conventional pipe 2fa bit,- having 1a bore I a,` therein', communicating an enlarged bore portion Ibi, in which tliesnolsi-l mallyrear end ofthe ktube ris-fitted; Thisitube 2s' a'hollow cylindricalmetal tube, preferably made of aluminum-#orithe like; and sl-idablyfposiei-q tioned therein-is the basket- 3,` which vis providedr` with a perforate bottom 3a andclip endkportionsf 3b, engaging, thev forwardf` open: endi 2a11of the; tuber2.

1 of thetube-Z, theforward end. ofthe diverter. 4e

is closed at 4c, adjacent the pipe bowl outlet passage 6a. The bowl 6 may be made of any suitable material, as desired, and externally fitted on the shank 6b thereof is the externally finned stem 5, which is a hollow cylindrical metal stem, having its rear end portion 5h surrounding the enlarged diameter portion of the bit I. The basket 3 is adapted to contain a filtering element, preferably tobacco, for the purpose of straining the smoke passing therethrough, preliminary to the passage thereof into the bore Ial of the bit I. It will be noted that the transition of the reduced bore la into the enlarged bore Ib` provides a trap for saliva which may travel forwardly in the bore Ia, whereby such saliva is absorbed in the tobacco within the basket 3 and prevented from returning and carrying nicotine to the smokers mouth through the bit I.

The operation of my pipe is substantially as follows: When the smoker draws smoke from the bowl 6 through the passage 6a, the smoke travels as indicated by arrows around the closed end 4c of the cup-shaped diverter 4, and in the space between the cylindrical wall portion of the diverter 4 and the stem 5. The tolerance intermediate the diverter 4 and stem 5 is limited so that efficient removal of the heat from the smoke and condensing the volatile fluids bearing nicotine is accomplished. After the smoke is passed rearwardly around the diverter 4, it travels inwardly through the openings 4b and along the outer wall of the tube 2, where additional con- -densing and cooling takes place, the smoke then passes as indicated by the arrows through the basket 3 containing the tobacco A, or other suit- 3 able filtering medium, as desired. After passing through the tobacco A the smoke passes through the perforate end 3a of the basket 3 and into the enlarged bore portion Ib at the transition with the bore portion la through which the smoke nally passes to the smoker.

It will be noted that saliva Which may gradually travel through the bore la drops by gravity into the enlarged bore portion lb and is absorbed by the tobacco A in the basket 3, preventing the same from returning laden with nicotine to the mouth of the smoker.

When it is desired to replace the tobacco A in the basket 3 and clean the pipe, the bit l is removed from the interior of the stem '5, then the diverter 4 is removed from the end of the bit I, the clip ends 3b are then removed from the tube 2, and the tobacco is carried therewith out of the tube 2 and replaced by fresh tobacco. All of the liquid condensed in the diverter d and the stem 5 may be drained when the bit I is removed from the stem 5.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement of parts, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claim.

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

A pipe having a hollow stem, and a bit provided with an enlargement and having an end in the stern, a smoke diverter comprising a tube extending within said hollow stem and having a closed end therein and an open end in frictional the stem, and having apertures adjacent the 4 open end for passage of smoke therethrough, an open ended cylindrical member having a diameter less than that of the diverter and adapted to be mounted within said enlargement in said end of said bit and extend into said diverter, and means adapted to support a filter within the cylindrical member comprising a perforated planar bottom having clip legs located at the outer periphery and perpendicular to the plane thereof, said legs terminating in relatively short outwardly directed 4 portions adapted to abut the edge of the free end of the cylindrical member to position said disk so that it lies in the plane of the other end of the cylindrical member.
