F-- FOREMAN Jan. 1, 1957 SMOKING DEVICE Filed Aug. 15, 1954 INVENTUR FRANK FOREMAN United States Patent ce SMOKING DEVICE Frank Foreman, Mimico, Ontario, Canada Application August 13, 1954, Serial No. 449,725

2 Claims. (Cl. 131213) The invention relates to an improved means of purifying the smoke in pipes, cigarette holders and like devices and the principal object of the invention is to provide a highly efiicient double-acting purifying means which will filter and settle out the tars and other undesirable and harmful ingredients of tobacco smoke.

Another important object is to provide a smoke-puritying means in which the filtering medium will be completely free from gumming-up due to saliva.

Still another important object is to efiectively cool the smoke as well as purify it.

Again it is an object to provide a smoke-purifying means as aforesaid of simple and inexpensive construction which can be quickly and easily cleaned.

The principal feature of the invention resides in carrying out the filtering and purifying in a double or twostage action in which the smoke is first filtered through a filtering medium located in one chamber and subsequently discharged into a second or settling chamber from which it is withdrawn by a mouth-piece.

With this arrangement the filter removes the bulk of the tobacco tar and similar ingredients from the smoke, and the remainder is subjected to a settling action to further reduce the percentage of such undesirable ingredients taken into the mouth of the smoker.

In this connection it is another feature of the invention to direct the smoke passing from the first chamber to the second chamber in a direction downstream of the flow of smoke up through the mouthpiece to augment the settling out action.

Further, with this arrangement, by having the filtering medium and mouth-piece in difierent chambers the saliva escaping from the mouth-piece is maintained from contact with the filtering medium, preventing its becoming gummed-up or plugged with a wet or sticky tar mass.

Another important feature resides in providing an arrangement of clean-outs whereby both chambers can be quickly opened and cleaned or drained.

These and other objects and features will become apparent from the following description taken in conjunction with the accompanying drawings, in which, Figure l is a mid-vertical sectional view illustrating my invention applied to a pipe.

In the embodiment of the invention illustrated in the drawing the block 3, which is provided with a first or upper inclined chamber 4' and a second or under inclined chamber 5 in 'side by side relation with the chamber 4, is formed also to define the bowl 24 of a pipe. Leading from the bowl 24 is a passage 25 extending downwardly from the interior of the bowl to the lower end of the chamber 4. A second downwardly extending passage 12' leads from the upper end of the chamber 4' into the chamber 5' adjacent the upper end. The lower end of chamber 4' is reduced as at 26 above the lower end of Patented Jan. 1, 1957 the passage 25 to form a peripheral shoulder 26 to locate a filtering medium 13' so that it extends between the

passages

25 and 12 and to provide a tobacco tar juice collecting chamber or receptacle at the bottom of the chamber 4'. The upper end of the chamber or passage 4' is closed by a cap 6 and the lower end of the chamber 5 is closed by a cap 8'. Received into the upper end of the chamber 5' is a nozzle 10' of a mouth-piece 9' corresponding to the mouth-piece 9 but having the curve of its upper end 11 somewhat more exaggerated. Closing the lower end of the chamber 4 is a further cap 27 corresponding to the caps 6 and 8.

The double action afforded by the device as a pipe construction illustrated in the drawing shows the cap 27 at fording a further clean out point for impurities received and collected below the filter 13.

It will be understood that various modifications and changes in details may be made without departing from scope of the appended claims.

What I claim as my invention is:

1. In a smoking device, a smoke purifying and tar eliminating means comprising two adjacent separate chambers inclining downwardly, the bore of the first chamber being reduced at the lower end to provide a heavy tar juice collecting chamber and to provide seating means for a filtering medium disposed within said first chamber, an inlet passage spaced from and extending throughout its length substantially above the lower end and within the reduced portion of said first chamber communicating with a source of tobacco smoke, an interconnecting passage adjacent the upper ends of said adjacent separate chambers, the second chamber comprising a moisture collecting and settling chamber and a mouthpiece leading from the upper end of said second chamber.

2. In a smoking device, a smoke purifying and tar eliminating means comprising two adjacent separate chambers inclining downwardly, the first of said chambers having a reduced cross section at the lower end to provide a heavy tobacco tar juice receptacle and a peripheral shoulder, a downwardly inclined inlet pass-age communicating with a source of tobacco smoke opening into said first chamber within said reduced portion said inlet passage spaced from and extending throughout its length substantially above the bottom of said chamber, a filtering medium disposed within said first chamber above and seated upon said peripheral shoulder and an interconnecting passage leading from said first chamber to the second chamber adjacent their upper ends, said second chamber constituting a moisture collecting and settling chamber and a mouthpiece leading from the upper end of said second chamber.
