PIPE.

To all whom it may concern:

Be it known that I, JACOB M. J oHNsoN, a citizen of the United States, and a resident of Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked part of this specification.

v This invention relates to improvements in tobacco ,pipes and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The object of the inventionis to supplya tobaccopipe having the simple lines of the usual pipe and provided with means located intermediate the mouth-piece and the pipefbowl to prevent particles-of tobacco from being drawn from the bowl into'the mouth and saliva from reaching the pipe bowl. 7

Other advantages of the pipe will appear as I proceed with my specification.

In the drawings :Figure 1 is a perspective view of a tobacco pipe provided with my improvements. Fig. 2 is a central longitudinal, vertical section through the pipe stem on an enlarged scale. Fig. 3 is'a crosssection through Fig; 2 on the line 33 thereof. Fig. 43is a cross section similar to Fig.

' 3 showing the parts in that position-which they occupy when the mouth-piece is about to be withdrawn from the stem. Fig. 5 is a cross-section through Fig. 2 on the 'line 55 thereof. Fig. 6 is across-section through Fig. 2' on the line 66 thereof; Fig. .7 is a perspective view of the inner end. of the mouth-piece.

In the drawmgs 10 indicates the bowl of the pipe; 11,-the ste'm, preferably made integral therewith; and 12, is the mouth-piece made of amber or any other suitable materiaL.

11 and l-2 are'theusual apertures, respectively, through the stem and the mouth piece, through which the smoke is drawn;

13 is an intermediate member between the stem proper and the mouth-piece proper in which are located the parts comprlsing my impro ements. Said intermediate member onsists of a cylindric tube, preferably of metal of the' diameter of the stem and closed at the rear end by a wall 13 which abuts Specification of Letters Patent.

against the end of said stem and forms a smooth unbroken surface at the junction of the stem with the cylinder 13.

14 is an apertured stud projecting on both sides of the wall 13* and having a screw-threaded rear end 14: which engages.

To the rear end of the mouth-piece 12is.

secured a semi-cylindric shell 15 which is shell 15 is preferably made integral with. a plug 15 adapted to be embraced by the front end of the cylinder 13 and having on its forward side a threaded stud 15 which is screwed into a threaded aperture in the rear end of the mouth-piece 1.2. The plug 15 is'provided with an aperture 15.

r 16 /is a short tube projecting within the cylinder 13 and preferably made integral;

with the plug 15*. It is located in line with the aperture 15 of said plug and is closed at its rear end by a baffle plate 16. 16 is a notch or opening cut in the side and bottom walls of said tube forward of the baffle plate.

It will thus be apparent that anything drawn into the aperture of the mouth-piece must pass about the lower edge of the batiie plate '16 before it may enter the aperture 15.

The rear end of the shell 15 is closed by an end wall 1 5 provided on its upper edge with a half-round notch 15' which is adapted to receive the front end 14" of thestud 14 when the parts are assembled. One edge of ftothe plug 15, which is adapted to be engaged by a pin or lug l7 projecting radially inward from the cylinder 13- to lock the shell 15 within the cylinder 13; A cylinder of absorbent material 18 is preferably 10- cated in the shell 15, with one end abutting against 'the plug 15, and the other against the end wall 15*- of said shell. This arrange- 'ment, insures the withdrawal of' the ab-.

sorbent cylinder with the shell.

From this construction itis apparent that any particles of tobaccothat may be drawn through the aperture 11 of the stem into the space within the'cylinder 13 will impinge against the baffle plate 16*. and drop mto the shell 15, or in the case of the use of the 70 adapted tofit within the cylinder 13.- Said A may be withdrawn and with it the semiabsorbent cylinder, into said cylinder. It

will thus be prevented from entering the] aperture of. the mouth-piece. It will also be apparent that any saliva that runs from'the 1 it' from the position illustrated in Fig. 3

where the pin 17 is engaged with thenotch v 17 to the position illustrated in Fig. 4: where the shell 15 has been rotated beyond the locking position, whereupon the mouth-piece cylindric'member 15 containing the absorbent cylinder. The parts may be thoroughly cleaned, and, if desired, a new absorbent cylinder placed within the shell 15.

I claim as my invention 1. In a pipe, in combination with the stem and the mouth-piece, a tubular member closed at its rear end by a wall, said wall being vprovided with an apertured stud having-a rear end engaged within an aperture "in said stem and a front end projecting within said tubular member, aplug secured to said mouth-piece adapted to'be embraced by the forward end of said tubular member, a small tube made integral with said plug opening into the aperture of said mouthpiece and closed at its rear end, said tube having a slot in its lower side forward of said rear closed end, and an open shell made integral with said plug adapted to fit within said tubular member, said shell having an. end' wall provided with a notch adapted to receive the forward end of said stud.

2; -In a pipe, in combination with the stemand the mouth-piece, a tubular member closed at its rear end by a wall, said Iwall being provided with an apertured studhav ing-a rear end screw-threaded into said stem and a, front end projecting within said tubular member, a plug secured to said mouth-piece adapted to be embraced by the forward end of said tubular member, a small tube made integral with said plug opening into the aperture of; saigLmouth-piece and closed at its rear end, said tube havingaa slot in its lower'side forward of said rear closed end, an open shell made integral with said plug adapted to fit within said tubular member, said shell havingan endwall -provided with a notch adapted to receive the forward end of saidstud, said shell being provided on one of its longitudinal edges with a second notch, and a pin or lug made rigid with said tubular member adapted to engage said notch to lock the parts in assembled relation.

3. In a pipe, in combination with the stem and the mouth-piece, a tubular member closed at its rear end by a wall, said wall being provided with an apertured stud having' a rear end screw-threaded into said stem and a front 'end projecting within said tubular membe, a plug secured to said mouth-piece ada ted to be embraced by the forward end of said tubular member, a small tube made integral with said plug openin into the aperture of said mouth-piece an closed at its rear end, said tube having a slot in its lower side forward of said rear closed end, an open shell made inte ml with said plug adapted to fitwithin sai tubular member, said shell having an end wall provided with a notch adapted to receive the forward end of said stud, and means for locking the-parts in assembled relation.

. I 4. In a pipe, in combination with the stem and the mouth-piece,- a tubular member closed at its rear end by a wall, said wall being provided with anapertured stud having a rear end screw-threaded into said stem I member, said shell having an end wall pro- 1 v vided witha notch adapted to receive the forward end of said stud, an absorbent member located in said shell, and means for locking the parts in assembled elation.

In testimony, that I, claim t e foregoing as my invention I affix my signature in the presence of two witnesses, this 2nd day of July A. D. 1910.
