Application filed March 28, 1913. Serial No. 757,467.

bacco pipe.

More particularly the invention relates to a pipe designed to provide better and surer draft than is ordinarily had in tobacco pipes; also to prevent passage of moisture from the mouth piece to the bowl, and passage of tobacco particles, juice and nicotin to the mouth; furthermore, to prevent clogging of the stem and bowl; and to permit of ready cleaning of all parts. I am aware that pipes have been constructed which are alleged to have some or all of these advantages. Such pipes have, however, usually been of complicated, or expensive structure, and of an unnecessary number of parts; often resulting in an article of grotesquev on inartistic design, and sometimes involving metal bowls, double chambers and other useless or ob ect1onable features.

The object of the present invention is a pipe of the character mentioned, in which the number of parts is reduced to a minimum; also one in which the pipe body and bowl may be integral, and of wood, or other accepted pipe material, having the flavor and coloring qualities demanded by critical pipe smokers and which in its entirety may be of pleasing and accepted deslgn.

The above and other features of the invention will more fully appear upon reference to the accompanying drawmgs in which- Figure 1 is a View in elevation the assembled pipe. Fig. 2 is a view in cross sectional elevation of the pipe bowl. Fig. 3

is a perspective view of the cap which closes the bottom of the bowl. Fig. 4 is a perspective view of the pipe bowl.

Referring to the drawings, the pipe bowl 1 is shown of one piece with the stem 2;

which latter has attached thereto, in any suitable manner, a mouth piece 3. The parts 1 and 2, which form the body of the pipe, are preferably of wood, meerschaum, or

other popular pipe material, such as will If desired,

however, the parts 1 and 2 may be separable, and may be of any suitable material. It will be noted that the exterior designs of the bowl and stem 2 shows nothing unusual in pipe construction.

Referring now to Fig. 2, it will be seen that the smoke passage 4. of the stem does not connect in the usual manner with the tobacco chamber 5 of the bowl. From the chamber 5there is a passage (5 which terminates at an opening 7 in the bottom of the bowl. The stem smoke-passage 4 leads direct to the bottom of the bowl, and terminates at the opening 8 therein. The bowl, for a short distance above the bottom thereof, is of cylindrical shape; and the cylindrical portion is exteriorly threaded, as shown at 9, to receive a cap. The cap (see Fig. 3) is in the form of a cylindrical cup, the base 10 of which is closed, and the top of which is open. The cup is threaded interiorly at 11 for engagement with the thread 9 on the bowl. Concentric with the base of the cup, and soldered or otherwise rigidly secured thereto, is a tubular member 12, having openings 13 through the side thereof at some distance above the base 10. The length of the tubular member 12 is such that when the cap is screwed home on the bowl, the upper edge of the tube will lie within a circular cut 14 in the bottom of the bowl, whereby the top of the cup is closed and sealed against passage of smoke. The cap may be provided with a milled edge 15 to provide a grip for the fingers in removing and aflixing the cap. The cap and the tubular member 12 may, in whole or in part, be of metal, rubberoid, wood or of any suitable material.

In operation, the tobacco is held in the bowl 5.- The passage 6, from the bowl cham her 5, is small enough to prevent escape of tobacco, except of dust and the like; but permits of free passage of smoke. Liquid or solid matter from the bowl will for the most part be caught in the bottom of the tube 12. The smoke, however, passes from the interior of tube 12, by way of openings 13, into the annular space 16 between the tube and the outer wall of the cap. The opening 8 from the smoke passage of the stem registers with the annular chamber 16, so that the smoke passing from the interior of the tube 12, by way of openings 13, may then enter the stem passage 4:, at which time it is cleared of liquids and solids, the latter having been deposited in the tube 12, or in the chamber 16. saliva which may pass down the stem will be deposited in the annular chamber 16 and cannot get to the bowl. Saliva in the chamber 16 will catch and hold any tobacco dust or other matter which is fine enough to pass the opening 13 with the smoke. The bowl is consequently kept dry and does not clog; and as nothing but smoke and saliva get into the stem, this also will not clog. When the accumulations in the tube, or in the annular "chamber outside 01" the tube, warrant it, the cap may be unscrewed and cleaned out; whereupon the pipe, on replacement of the cap, is again substantially as clean as when originally used.

It will be noted that the only necessarily adjustable or removable part is the cap. Also that the stem passage has no abrupt turn; wherefore, a straw or the like. can be readily passed from one end to the other of the stem to remove any obstacle which may accidentally enter from either end. The passage from the top of the bowl tothe bottom thereof is also without turns; and, in event any tobacco or other obstacle should I by chance clog the passage 6, it may easily be removed. 7

A preferred form of the invention has been shown in the drawings. It will readily be understood, however, that, within the scope of the invention, the shape, material, number of parts, and other features 01 the pipe, may be considerably modified or changed.

VJ hat I claim is: I

1. A tobacco pipe having a tobacco receptacle; a cup below the receptacle in sealed engagement therewith means whereby the cup may be detachably secured as a whole directly to the receptacle, said cup comprising two chambers, each closed at the bottom, but in connection with each other above the bottom; a stem, the smoke passage of which opens into one of said chambers, and said receptacle having a passage from of the receptacle being in communication with the other of said chambers.

3. 21 tobacco pipe havinga tobacco re- A ceptacle; a cup, the open end of which is threaded onto the base of the receptacle; a hollow member closed at the bottom, integral with the cup, of less diameter than the cup, and concentrically seated within the cup, the interior or which hollow member is in communication with the interior of the receptacle, and also with the chamber between the cup and said hollow member, and a stem in communication with said last named chamber.

a. A tobacco pipe having a tobacco receptacle; a cup, the open end of which is detachably secured to the base of the receptacle; a hollow member closed at the bottom, integral with the cup, of less diameter than the cup, the interior of which hollow member is in communication with the interior of the receptacle, said cup being closed at'its top by the bottom of the receptacle except for said communication with the interior of the receptacle, but having an opening through its side into the chamber between it and the wall of the cup, and a stem in communication with said last named chamber.

Signed by me at New York city, N. Y. this 11th day of February, 1913.
