CHARLES A. ALDEN, OF STEELTON, PENNSYLVANTA.

TOBACCO PIPE.

Application filed March 23, 1925. Serial No. 17,514.

To all whom it may concern:

Be it known that I, CHARLES A. ALDEN, a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Tobacco Pipes, of which the following is a specification.

This invention relatesto improvements in that class of tobacco pipes wherein the pipe stem extends from the upper portion of the pipe bowl and wherein parts of the pipe are separable from one another for cleaning p r s The object of my invention is to provide a pipe having parts of novel construction which-may be manufactured at low cost and which are so constructed and related to each other as to provide a smoke passage between the tobacco receptacle of the bowl and the mouth piece of the stem which may be easily and quickly cleaned and which will effectually prevent the semi-liquid and other ob jectionable matter which finds its way into the various parts of the passage, as a result of the smoking operation, from reaching the mouth piece and being discharged therefrom, while the pipe is being smoked, and from being returned to the tobacco receptacle when the pipe is turned or inverted.

With the foregoing and related objects in View, the invention consists of the elements and the combinations of them hereinafter described.

In the accompanying drawings, illustrating my invention,

Figure 1 is a top view of my improved pipe.

Figure 2 is a longitudinal section of the pipe, on line 2-2 of Fig. 1.

Figure 3 is ahorizontal section through the pipe bowl, on line 33 of Fig. 2.

Figure 4 is a top view of the detachable base member of. the bowl.

Referring to the drawings, 4 designates the pipe bowl having the hollow portion 5 which forms a receptacle for tobacco to be smoked therein.

The bowl 4 is provided with a stem 6 which extends outwardly from the upper portion thereof. The stem 6 has an axial opening or socket 7 extending inwardly from the outer end thereof for the reception of the reduced end portion 8 of a mouth piece 9 which forms, inefi'ect, a continuation of the stem 6. The mouth piece 9 may be detached from the stern by withdrawing the reduced end portion 8 thereof from the opening 7 and, when the end portion 8 is inserted int-o the opening 7, the frictional engagement of the parts holds the stem and mouth piece together.

The bottom portion of the bowl. 4 is made hollow and the hollow portion is interiorly screw-threaded, as shown in the drawings. The hollow bottom portion of the bowl carries a base member 10 which is exteriorly screw-threaded and screwed into the same and'the bottom of which is provided with an outwardly-projecting, annular flange 11 adapted to engage the bottom surface of the bowl 4 and limit the movement of the base member 10 when it is screwed into the bowl. The flange 11 also serves as a hand grip for the base member 10 when it is unscrewed to remove it from the bowl.

The base member 10 is so related to the bowl 4 that when it is screwed into the same a space is provided between the top of the member 10 and the bottom wa1l'12 of the bowl 4 forming a chamber 13 between them. The central portion of the top wall 12 of the chamber 13 has an upwardly extending hollow or cavity 14 formed therein, and the central portion of the top of the base mem ber 1.001 bottom wall of the chamber 13 has 'a downwardly extending hollow or cavity 15 formed therein beneath the cavity 14, as

clearly shown in Fig. 2, for purposes hereinafter described.

The mouth piece 9 and stem 6 have central smoke passages 16 and 17, respectively, therein, forming continuations of one another; the bowl 4 has a smoke passage 18 therein which communicates at its lower end with the chamber 13 and at its upper end with the passage 17 in the stem 6; and the wall 12 of the bowl 4, forming the bottom of the tobacco receptacle 5, has passages or ports 19 therein which connect the hollow portion or receptacle 5 and the chamber 13.

It will now be understood that the ports 19, chamber 13 and passages 18, 17 and 16 opening 20 therein above the upper end of the'passage'18 and communicating with the passages 17 and 18; This opening 20 is normally closed by a screw'threaded plug 21 which is screwed into the opening 20 and which is provided with a suitable head 22 by means of which the plug may be handled. The head 22 also serves to engage the top of the bowl and limit the movement of the plug when it is screwed into place.

When the plug 21 and base member 10 are removed from the bowl 4., the opening 20 in the bowl 1 together with the smoke passage 18 therein provides a straight and unobstructed opening ofthe full diameter of the passage 18 from the space beneath the bowlto the space above the same. This construction not only permits the passage 18 to be easily drilled or otherwise formed by a suitable instrument in making the pipe, but it also permits a cleaning device to be passed through the passage in a straight line when it is desired to clean the same. The opening 20 also serves to permit an entire cleaning device to be passed completely through it and the smoke passage 17 when the mouth piece 9 and plug 21 are removed and it is desired to clean the passage 17.

The cavity 15 in the base member 10 provides a settling basin for the accumulation therein of the semi-liquid and other objectionable matter, well known to smokers, which finds its way into the chamber 13 and the other smoke passagesot the pipe. After the base member 10 has been removed from the bowl 1, this objectionable matter may be readily cleaned from the cavities 14 and '15 and other parts of the chamber 13.

The arrangement of the cavity 15 directly beneath the cavity 14, and the arrangement otthe passage 18 and ports 19 outwardly or laterally of the cavity 1 1, causes the ac- .cumu'latedmatter within the cavity 15 to be discharged into thecavity 1 1 and prevents it from entering the passage 18 and ports 19 when the pipe is inverted, and causes the said matter to be returned'to the cavity 15 'when the pipe is turned rightside' up after being inverted. i

It will beobserved that'the screw "threads of the base member lO-surround the cavity 15 therein outwardly thereof. This con struction separates the threads from the cavity andthereby prevents the accumulated matter within the cavity from reaching the threads by gravity when the member 10 is removed for cleaning purposes, thereby keeping the threads clean and ready for replacement after the fouled parts of the pipe have been cleaned.

I claim as'my invention 1. A tobacco "pipe comprising a bowl forming a tobacco receptacle, a stem extending from the upper "portion of-th'e bowl,
