2 Claims.

My invention relates to a pre-formed load or cartridge for use in a tobacco pipe.

This application is a division of my prior ap plication Serial No. 114,293, liled December 5, 1936, for a Tobacco pipe and load now Patent No. 2,091,440 of August 1937.

Among the objects of my invention are: To provide a load for a pipe whereby the load may be cooled during the smoking thereof; to provide a pre-formed tobacco Cartridge which may be accurately positioned in a tobacco pipe; to provide a cartridge cooperating with a tobacco pipe to form an air space between the cartridge and the pipe bowl; to provide a tobacco cartridge containing a iilter; and to provide a tobacco cartridge containing a flavor.

Other objects of my invention will be apparent or will be specifically pointed out in the description forming a part of this specification, but I do not limit myself to the embodiment of the invention herein described, as various forms may be adopted within the scope of the claims.

Referring to the drawing:

Figure 1 is a view partly in section and partly in elevation of my invention as utilized in a tobacco pipe having a split bowl.

Figure 2 is a sectional View of the cartridge and pipe shown in Figure 1.

Figure 3 is a sectional view of another form of cartridge.

I am well aware of the fact that cartridges containing tobacco in a combustible wrapper have been used in the past, but in most cases such cartridges have simply been used as a convenient means for loading a pipe. I am also aware that under certain circumstances cartridges have been inserted in pipes in such a manner that the bottom portion of the cartridge frictionally engages the lumen of the pipe at its lower end only, presumably leaving an air space between a short portion of the charge and the bowl of the pipe.

'I'his latter form of cartridge, however, has not proved satisfactory in use, inasmuch as it is necessary to press on the outer end of the charge in order to force the lower portion into supporting contact with the pipe bowl. The force necessarily used almost invariably splits the wrapper and the tobacco completely fills the bowl, eliminating any air space.

I have, however, invented a unitary charge for insertion within a pipe bowl in such a manner that when the pipe is properly made no force is necessary to position the charge, and there willat all times be a complete airspace between the burning charge and the wall of the pipe. This air space allows air to circulate around the burning n I charge, prevents the bowl of the pipe from eX- cessive heating, and makes for a much cooler smoke than can be obtained in the ordinary pipe. Inasmuch as no pressure is placed upon the wrapper of the cartridge it does not break, but maintains its relative position until the charge is consumed.

My invention also utilizes a filter in connection with the cartridge, and if the tobacco is to be iiavored I place the flavor in the filter, not in the tobacco. In this latter manner I am able to utilize the same tobacco for a large number of cartridges carrying different avors, thus making for cheapness of assembly. My pipe construction insures proper alinement of the cartridge.

Other advantages of my invention may be more readily understood by direct reference to the drawing.

Figure 1 shows one preferred form of pipe utilizing my cartridge. The pipe has the customary mouthpiece I fastened to a stem 2 in the usual manner, and it is of course obvious that any of the saliva collecting devices may be used between the mouthpiece and stem,

I prefer to form my pipe with a split between bowl and stem, stem portion 3 being provided with threads 4 cooperating with bowl threads 5 cut into a bowl 6, the outside of the pipe being smooth when assembled.A

Thus, I have provided a pipe which carries two shoulders within the smoking chamber; a bowl shoulder 'I and a stem shoulder 8, which may be utilized to clamp and position a charge supporting flange extending laterally from tobacco .l cartridge 9. This cartridge is Well illustrated in two modifications in Figures 2 and 3.

In Figure 2, a cup I0 is provided with the peripheral supporting flange I I, and a body portion I2 provided with perforations I3 at the bottom thereof, the latter perforations opening into stem chamber I4. In this case the cup extends downwardly into the stern chamber I4, and the cup is lled with lter material I5. The cup itself is preferably formed from an asbestos or l other non-burning material, and likewise, the iilter material I5 may be of finely divided asbestos liber or similar material so that it also will not burn.

A charge of pipe tobacco I6 is surrounded by a combustible wrapper I "I, the latter extending into the cup and preferably cemented thereto so that the charge I6 is supported by the cup in upright position.

To insert the cartridge 9 in the pipe all that `its is necessary'to do is to unscrew the bowl from Y ing the charge upright, and inasmuch as the cupV side wall contacts the shoulder 8 Vit is obvious that the charge is always centered. f I prefer to make the charge ofJsub'stantially lesser diameter than the bowl interior, so Vthat an 'air space-*I8 is provided between the bowl and the charge; and I prefer that this air .space become increasingly large as the end ofthe charge is approached although this is not necessary, but increases the cooling effect. I also prefer that/no bowl 'material shall touch the burning tobacco, and therefore in this particular modification vI have provided an air gap I9 between the lowerv level of the charge I6 and the upper shoulder 1.

Another modification is shown in f Figure 3. Here, the cup body is turned upwardly, and instead of projecting into chamber I4 it projects away from chamber lil-and enlarges this-chamber. In this case I omit the air space I9 between the cartridge and the upper shoulderJI; and the 'upper shoulder l, itself, serves toposition the charge .in a central position. In this case the Y filter .material is not placed in the cup, but is placed between the bottom of the cup and the bottom of the charge, and is surrounded by the combustible .wrapper I'I insteadV of bythe .cup material. In-this instance the tobacco charge I does not approach closeto the bowl walls at any point, and therefore Yat no time during the smokingr of the charge will the bowl be in contact with the burning tobacco. Y

It is to be noted that my improved cartridge and cooperating pipe assures the fact that a comparatively large air space shall always be left between the burning charge and the bowl of the pipe. No pressure is needed to force the cartridge in place, the charge being held solely by shoul- Y ders 'I and 8. No pressure is necessary on the outer end of the charge, and therefore the combustible wrapper is never broken and the charge is maintained iniV position untilV entirely smoked.

Due to the fact that this wrapper is never broken,

Yit will confine the charge of `tobacco without the bined with the tobacco itself. If a large number readily takes up flavor, and during shipment ofY the tobacco the tobacco in each charge is permeated with'the flavor in the filter, and, in addition,-during the smoking of the charge the smoke isrdrawn through the filter and becomes impreg- Ynated withthe flavoring material. lI am thus Y able to supply the smoker with a'large number of flavors at a minimumcost, and Ihave successfully flavored tobacco in this 'manner with anise, menthol, walnut, maple, rose, apple, etc.

' Theflavors., of course,may be used alone or in Y Vcombination to V suit the smoker., n

summarizing, I have provided a compact cartridge comprising tobacco, wrapper, lter and avoring material, together with a firm and solid means whereby the cartridge may be supported in conjunction with clamping shoulders in a split bowl pipe. The charge is centered and held in Y the pipeby a special flange so that there is a complete air space around the entire charge during Vthe entire time of smoking. No pressure is necessary to place the charge in the pipe and,

therefore, the combustible wrapper of the cartridge is never broken. A cool and avored smoke is obtained with no chance of the burning tobacco ever touching the bowl. Y

VI may, however, desire to still further improve the coolness of the smoke by providing in the Vbowl of the pipe adjacent the lower portion of the charge, air inlet apertures 20. The size an-d number of these apertures are not important to my invention but they should be'suflicient so thatV a draft is provided between the lower and upper portion ofthe bowl, and in order to equalize the draft, I prefer to position these apertures circumferentially around the bowl. Furthermore, I increase the flow of Vair through the space I9 by directing the aperture bores at an angle so that any downward motion of the pipe causes Y.

air to pass along the sides of the burning charge. Inasmuch as the pipe is usually in more or less continual motion, such motion aids the cooling by forcing the air past the charge in addition toVV per forming a wall constitutingthe sole means," to retain tobacco in position above the cup, said a wrapper and the side wall of said cup being substantially coextensive, a charge of tobacco in said wrapper, and a mass of filter material within said wrapper in contact with said tobacco and sup- 2. A unitary self-supporting tobacco cartridge consisting of a cupv formed of a singlerpieceof material and provided with a laterally extending clamp-ing iiange and having a perforated bottom, a combustible wrapper within and attached to the cup in abutting relation therewith, said wrapper forming a wall constituting the sole means to retain tobacco in position above the cup, said wrapper and the side wallY of said cup being substantially coextensive, a charge of tobacco in said wrapper, and a'mass of filter material within said wrapper in contact with said tobacco and supported on the bottom of said cup, said flange constituting the major transverse means to retain the cartridge within apipe bowl against withdrawal movement, said filtering material be'- ing incombustible and containing a flavoring material which is adapted to permeate said tobacco charge during storage.
