2,702,039 SMOKING PIPE Werner Siebert, Rutherford, N. J. Application May 11, 1950, Serial No. 161,291 4 Claims. (Cl. El 193) This invention. comprises novel anduseful improvements in a smoking, pipe and more specifically pertains to a smoking pipe having a combustion chamber with a movable cover closing the upper end of the same-together with a removable ashpit'for the bottom of the chamber.

The primary object of this invention is to provide an improved smoking pipe which? shall have asubstantially sealed combustion chamber anda removable ashpit;

A further objectof the invention is to provide an improved smoking pipe in conformity with: the preceding object'in which the movable closure for-the combustion l United States Patent chamber shall be pivoted to the bowl of the pipe and wherein the smoke discharge passage from the combus1 tion chamber shall be carried through the pivot of the combustion chamber cover.

' Still another important object of the invention-is to provide an improved smoking pipe as set forth inthe I foregoing objects in which a -removable cap is provided for the lower end of the combustionchamber to form an ashpit therefor, together with air vent or draft openings for supplying air to supportthe' combustion within the chamber.-' ft -An additional important object; of the invention is to provide an improvedi'constructiorl of smokingpipe in accordance with the preceding objects in which. the co mbustion chamber is divided into upper and lower compartments by the'provis'ionof a tire grate in the chamber,

and wherein the pipe may be charged from the top, and the charge may be ignited, and the ashes of combustion may be removed from the lower end-of the combustion chamber.

These, together with various ancillaryfeatures and objects of the invention, which will later become apparent as the following description proceeds,j are attained by the present invention, a preferred embodiment of which has been illustrated, by ,wayof example only, in the accompanying drawings, wherein; t

Figure 1 is a vertical central sectional view through a smoking pipe incorporating therein the principles of this invention, an alternative position of the closure cap and ashpit of the pipe beingindicated in dotted lines therein and with the perforatedpartial, cylindrical'sleeve therein shownin elevation; V

Figure 2 is a horizontal sectional View taken upon the plane indicated by the section line 22 of Figure l; and

Figure 3 is a horizontal sectional view taken upon the plane indicated by the section line 3--3 of Figure 1.

Referring now more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, it will be seen that the invention has been embodied in a more or less conventional shape and form of pipe, the same consisting of a bowl 10 having integrally formed therewith a stem 12 which detachably receives a mouthpiece 14. Obviously, these elements may all be of any sutiable material, shape or size as desired.

However, the stem includes a preferably straight bore or passage 16 which has a spiral strip metallic body 18 removably positioned therein for condensing moisture from the tobacco smoke. This condenser spiral thus serves particularly to filter the smoke from the pipe, by condensing the moisture therein and cooling the smoke. The mouthpiece 14 is provided with a medially disposed passage 20 communicating with the passage 16. By removing the mouthpiece, the member 18 can be readily removed and the moisture drained from the bottom of the passage 16.

The member 18 could he of various forms and materials, as for example, of a str'p of aluminum foil, spirally wound to leave an axial opening.

- The lower portion of the passage 16, indicated by the numeral 22, constitutes a moisture trap.

The bowl of the pipe is provided with a chamber 24 extending completely therethrough from the top to the bottom of the bowl, and open at both of its extremities. The open upper end of the chamber 24 is provided with a pivoted cover or closure 26 in the form of a cap or the like,'the same having a chamber 28 formed by a concaved surface on the underside of the closure, and it will be noted that the adjacent surfaces of the cover '26 and of the bowl 10 are coterminous or join upon a horizontal plane as shown in Figure 1. V

The closure 26 is pivotally mounted upon and secured to the bowl 10 by means of a portion thereof having a bore or passage 30 opening from the bottom surface of thecover 26, which bored portion is pivotally mounted uponthe upwardly and vertically extending portion 32 of a pivot 34, this pivot comprising a sleeve or tube having an angularly disposed lower end 36 which is embedded in the material of the bowl 10. An outlet passage 38 is formed in the material of the cover 26 and connects the chamber 28 therein with the interior of the pivot 34, WhlCh, in turn, communicates with a conduit 40 whose exit discharges into the'interior of the passage 16 midway of the length thereof.

,The upper portion of the bowl 10 has an upstanding cylindrical flange 25 which is received Within the chamber 28 of the cap 26 to efiect a better seal at the closure joint.- The portion having bore 30 is both rotatable and slidable upon the pivot portion 32 so that the cover 26 can be raised to-clear the flange 25 before the cover is thus rotated into open position.

It will thus be seen that the pivot member 34 serves the dual functions of constituting a hinge or pivot about which the cover 26 may rotate when it is desired .to cover or uncover the upper end of. the combustion chamber'24, and also constitutes a part of the smoke conduit'connecting the chamber 24 with the mouthpiece 14. Adjacent its openlower end, the chamber 24 has frictional-ly secured therein a foraminou's or perforated sheet metalpartial: cylindrical sleeve 42, the same having air admitting perforations 44 throughout its side. The sleeve 42- is provided with a flange 45 extending. radially outwardly therefrom at its upper end. A screen46 constituting a grate is supported on the flange 45 in any suitable manner. The sleeve 42 is preferably slotted along one side thereof, with the edges of the slot being of an undulating shape as shown at 48. If desired, an annular groove 49 may be disposed appropriately in the side of the chamber 24 in order to form a stop or seat to prop-- gr'ly position the flange .45 and the grate 46 in the cham- As will be readily apparent from the above description the sleeve 42 and the grate 46 are inserted from. the open lower end of the, chamber '24. and are frictionally held in place by the resilient action of the flange 45 upon the cylindrical wall of the chamber 24. The provision of the slot in sleeve 42 performs a twofold purpose, that of providing a means whereby the sleeve can be compressed in order to adjust the same and that of providing a slot for inserting the lighted end of a match beneath the grate 46 for igniting a charge thereon when the cap member 50 is slid downwardly as stated below. Further, the sleeve 42 may be rotated whereby the slot will be disposed on the proper side of the pipe which is most convenient for the person using the same.

A closure cap combined with an ashpit is provided for cooperation with the open lower end of the chamber 24. For this purpose, a body member forming the cap and indicated by the numeral 59, is provided, this member numerals 56 and 58, respectively functioning as combustion chamber and ashpit.

The bottom wall 54 is provided with any desired number of vents or apertures '60, the same functioning to admit the combustion supporting air into the bottom of the ashpit, and upwardly through the grate 46 into the combustion chamber. The cap or ashpit member 50 is removably and slid ably secured to the bowl 10. For this purpose, the cap 50 is provided with a longitudinallyrextending rib or key 62, see Figure 3, which is dovetailed in shape and is received in a dovetailed channel 64 formed on the adjacent vertical surface of the bowl 10, at the lower and cut away portion of the same.- A suitable gasket or other means 66 is mounted upon the lower surface of bowl to form a seat for the upper edge of the cap member 50. The frictional engagement of the key 62 in the channel 64 is such as to retain the cap member 50 in slidably adjusted position. In the closed position shown in full lines in Figure 1, the upper edge of the cap 50 is pressed against the seat member 66, and forms an air-tight closure for the lower end of the chamber 24, except for the air supplying vents or apertures 60. However, when the member 50 is pulled or slid into its lowered position, as shown in dotted lines in Figure 1, a slot or opening is formed whereby access may be had to the interior of the ashpit 58 through the slot in sleeve 42 for depositing a lighted match or the like into the same for initiating combustion in the pipe.

When it is desired to charge the pipe it is merely necessary to slide the cover on the pivot 34 and rotate cover 26 into the open position as described and place a charge above the grate 46. In order to empty the contents of the ashpit, the frictionally held screen 42 and grate 46 need not be removed, as the closure 50 may be slid downwardly to the dotted line position or entirely withdrawn. Ignition is eifected by first closing cover 26, sliding closure 50 down to the dotted line position, and then placing a lighted match through the slot of the sleeve while applying suction to the mouthpiece. After the charge has sufficiently ignited the closure 50 is moved to closed position.

It will thus be evident that once the pipe has been charged or loaded, it is not necessary to open either the combustion chamber or the ashpit throughout the entire operation of the pipe, 'so that a relatively cool, pure and dry smoke can be obtained from the tobacco. The less volatile residues of the burning tobacco may descend with the ashes below the grate 46 into the ashpit; or may be retained upon the grate in thecombustion chamber, while the smoke itself will be discharged through the above described smoke outlet passage. 7

From the foregoing, the construction and operation of the device together with its many advantages will be readily apparent and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
