AppIicaton filed October 11, 1916. Serial 1\To.` 125,079.

To all whom t may concern: v

Be it known that 1JOHN` E. BRADLEY, a citizen ofthe United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented certain new and useful Improvements in T obacco-Pipes, of which the following is a specification.

This invention relates to tobacco pipes, and more particularly to a pipe of that type inwhich the suction or smoke openings are positioned adjacent the upper end ofV the pipe bowl. f

One of the main objects of the vinvention is to provide a pipe of the character stated of simple construction and operation provided with a casing or magazine from .which tobacco may be supplied directly to the interior of the pipe bowl. A further object is to provide means for exerting constant upward pressure on the tobacco contained in the pipe bowl so as to gradually force the same toward the upper end of the bowl as it is consumed. A still further object is to provide a pipe having the suction openings so relatively disposed as to insure even burning of thetobacco. Further objects will appear from thedetail description.

The cylindrical bowl 1 of the pipe is provided, lat its upper end, with an internally threaded enlargement which receives the eX- ternally threadedneck 2 of the fire bowl 3. The lower end of this yneck ts snugly against the upper face of the annular shoulder contiguous with the inner cylindrical chamber of bowl 1 so as to effect a tight closure therewith. The re bowl 3'is`pr-ovided with an external annular shoulder 4, and, at its upper end, with an inwardly 'directed annular shoulder 5 which is concentric with the frusto-conical opening at the top ,of the fire bowl. The fire bowl is further provided with a plurality of downwardly and outwardly inclined smoke ducts 6. These ducts communicate with theY interior of the re bowl a short distance below the annular shoulder 5. There are four of these ducts in all, and they are spaced 90Q apart about the tire bowl, the ducts of one side of the fire bowl communicating at their lowerends with a horizontal groove 7 formed in the upper face of the smoke collecting ring 8 which is threaded about the neck 2 of the tire bowl between the upper endof pipe bowl 1 and shoulder' 4:. -The two ducts at the other side ofthe tire bowl communicate with a similar groove 7a in the upper face of smoke collecting ring 8. Each ofthese grooves is connected by a vertical duct 9 with `an approximate semi-circular groove 10 formed in the underfacejof smoke collecting ring 8. This groove 10 communicates with a vertical smoke passage 1l extending downward in the wall of pipe bowl 1 which communicates with a smoke passage 12 formed in a neck 13 of the pipe bowl. Neck 18 is threaded to receive the usual stem 14. By this means smoke may be drawn from the re bowl through the stem, and this smoke is taken from four equally spaced points within the tire bowl, thus insuring even burning of'thecontents of this bowl. A short by-pass 15 communicates with thesmoke passage 11, 'atits juncture with the smoke passage 12.l This bypass is directed downwardly and outwardly and is normally closed by a stopper 16. The by-pass 15 provides .a collecting chamber for any nicotin or tobacco juice which may get into the smoke passage, and these accumulations can be quickly and easily removed by Vremoving stopper 16 from the pipe bowl.

A tobacco holding chamber or magazine 17 is secured to the front ofubowl 1 and communicates with the interior thereof through a slot or passage 18. This magazine is provided, in each side near the outer edge thereof, with a longitudinally extending groove 19. These` grooves are adapted to receive the turnedover flanges 20 of a sheet metalV cover .21 so as to secure the same slidably on the magazine. The upper end of this cover is turned over to provide a flange 22 which engages the top of magazine 17 thus preventing the cover `from moving?,- dQWIl.- ward from in front oli the magazine.l As will be evident, the cover may be raised, when desired, so as to open the magazine.

A metal cylinder 23 open at both ends fits snugly within the cylindrical interior chamber of bowl l. This cylinder is provided, near its lower end, with a groove which receives the inner end of a catch 2st Apivotally mounted on the bottom of pipe bowl l by means of screw post 25. rllhis catch acts to normally hold the cylinder within the pipe bowl. Cylinder 23 is of such length that, when in operative position, it extends to the inner end of neck of the lire bowl. This cylinder isA provided with a longitudinally extending slot Q6 which is normally in register with passage 18 of magazine 17.

Y fr cylinder 27 tits snugly within the cylinder 23 and is open at its upper end. This cylinder is secured in adjustment in cylinder 23 by means of a set screw 2S threaded through vcylinder Q3 and engaging cylinder 2'?. The lower end of cylinder 27 is closed by a disk 29 secured therein. A. head 30 is slidably mounted in the cylinder 27 and lits snugly within the same. This head is forced upward by means of acoil spring 31 confined between ythe same and disk 29. ri rod 32 is secured through head 30 at the center thereof and is slidable through an opening through the center of disk 29.

'ln using the pipe, the cylinder 27 is drawn downward, after releasing the same trom set screw 2S, so as to uncover the slot 26 of cylinder 23. When this has been done a suitable quantity of tobacco may be forced from the magazine 17 into the pipe bowl, the head 30 being drawn downward by means of rod 32, this tobacco falls into the cylinder 27 above the head. When a suitable chargey has thus been forced into cylinder 27, this cylinder is returned to position to shut oli communication between the pipe bowl and the magazine. The spring 81 will act by expansion to torce head 8O upward thus forcing the charge ol? tobacco into the lire bowl 3. This tobacco will engage the annular shoulder 5 at the upper end of `the bowl which will prevent the tobacco from being forced entirely out of the bowl. The top of the charge is then ignited in the usual manner, the smoke passing downward about the lire bowl into the stem 11i. As the tobacco is burned., the ash produced will Vhave very little resistance and will thereiore be forced upward out of the top of the bowl permitting the tobacco within the pipe bowl to be gradually forced upward as it is consumed. By this means the smoke is taken from the top portion of the tobacco charge and does not pass downward throughV a relatively large mass of tobacco as in the common form of pipe. This prevents, to a large extent, excessive heating of the tobacco Within the pip@ bowl thu-S eliminating the creatiQll oi' large quantities of nicotin within the pipe. By adjusting the cylinder 27 within cylinder 23 the pressure on the tobacco within the pipe bowl may be adjusted as desired.

`When Vit is desired to clean the pipe bowl the cylinders 23 and 27 may be quickly and easily removed, as may also the lire bowl 8. This leaves the pipe bowl in the form of a cylinder open at both ends thus permitting ready access to the interior of the same.

The modified form shown in Figs. G to 8 of the drawings is very similar to that shown in Figs. Ito 5. lin this form the `re bowl 3 is replaced by a ring 33 provided in its outer facie with two ,diametrically oppoite vhorizrnital.grooves Sil which communicate at their ends with the interior of the `ring through ports 35. Each'of the grooves 3a is connected by a vertical passage 36150 a horizontal passage 37 which communicates through a short vertical passage 38 with kthe smoke passage ll of pipe bowl 1. The action or' this imodiiied form of pipe is similar to that previously described in connection with the term shown in Figs.. 1 to 5 of the drawings, the `smoke ring i0 being replaced by a sleeve 39 which fits snugly about ring 33. This sleeve acts to coniine the smoke and cause the same to flow downwardly into the smoke passage and thence into the stemofthe pipe.

There may be slight changes made in the construction' and arrangement of the ditier- 100 ent parts of my linvent/ion without departing :from the iield and scope of the same, and l intend to include all such variations, as fall within the scope of the appended claims, in this application in which a -pre- 105 ferred form only of my invention is disclosed.
