Patented Aug. 13, 1940 TATES PATENT oFFic SMOKERS PIPE AND CONDENSER THEREFOR Claims.

The present invention relates to smokers pipes and has for its important advantage the provision therein or" a distillate condensing, removable capillary collecting cartridge, which not only 5 condenses and collects out the tarry deposits from the burning tobacco, but also prevents saliva from the smokers mouth from reaching the bowl of the pipe.

Another feature of advantage is that the cartridge is non-absorbable, is removable and cleanable, and does not therefore require replacernents, the materials of the cartridge being substantially indestructible.

In one of the forms shown herein the condenser comprises a metallic, protective fine wire screen in which is contained a distillate condensing woven glass textile, or cloth, this combination having been found to be extremely effective for the purpose described.

Modifications may be made in the structure herein disclosed, without departing from the spirit hereof or the scope of the appended claims.

In the drawing,

Fig. 1 is a longitudinal section of a smokers pipe showing the present improved condenser in operative assembly therein;

Fig. 2 is an enlarged, longitudinally sectioned view of one form of condenser;

Fig. 3 is a transverse sectional view of the condenser of Fig. 2, taken on the line 3-3, Fig. 2,

looking in the direction of the arrows;

Fig. 4 is an enlarged, longitudinal sectional view of a modified form of condenser;

Fig. 5 is a transverse sectional view of the condenser taken on line 5-5, Fig. 4, looking in the direction of the arrows;

Fig, 6 is an enlarged, longitudinal sectional view of a further modified form of condenser;

Fig. 7 is a transverse sectional view taken on the lines l-l, Fig. 6, looking in the direction of the arrows; and i Fig. 8 is an enlarged side view of the condenser cartridge holder removed from the pipe stem.

The' assembled structure of the pipe, generally denoted by i, is shown in Fig. 1 and comprises a moulded bit or stem 3, into which is integrally moulded a metallic condenser cartridge holder, shown separately in enlarged proportions in Fig. 8. The holder is in one piece and has one end 5 provided with a diamond knurling on its outer surface operatively fix the holder to the pipe stem y moulding the holder into the stem, when the stem is made.

The holder is provided with an integral, surrounding flange 4, at about its mid-section, to

act as a stop flange and ferrule. The end 5 of the holder opposite the knurled end 5, is cylindrical to fit the bore it of pipe stem 2, and is provided with slot it, which extends across the central bore l5 of the holder, and through the 5 opposite side of the holder, to make this slotted end of the holder resilient, so as to removably grip the condenser cartridge when it is in operative position in the stem 3, as shown in Fig. 1. When the stem his removed from the pipe, in the condenser cartridge is removed from wooden pipe stem 2, with the moulded holder stem 3.

The condenser cartridge of Figs. 2 and 3 is made up of two drawn metal end caps 8, the head ends of which are slightly inverted and are it provided with draft perforations 9-9, Fig. 2.

A piece of flat metal fine mesh screen is rolled up into a cylinder l, with an inside lap iii, Fig. 3, and while in this form the caps 8-8 are assembled on the ends of the cylinder '5, and the jm mesh cylinder being resilient, expands its ends into a firm operative fit with the caps. The interior of the cylindrical mesh screen i may be provided with a condenser filler such as a clothlike woven glass textile/which like the screen 25 cylinder 7, may be boiled in water, or cleaned in alcohol, without detriment, thus to cleanse the cartridge, as required from time to time. The complete cartridge is thus made up of nonabsorbent materials the surface areas and inter- 30 stices of which act to condense and capillarlly collect the products of distillation from the tobacco. When the condenser is clogged, it may be removed, boiled or cleansed with alcohol and replaced, as previously described. 35

In Figs. 4 and 5 there is disclosed a condenser similar to the one described and shown in Figs. 1 and 2, with the exception that the cylindrical mesh is comprised of :3. rolled up piece of metal condenser screen i of fine mesh, the interior of the cylinder being filled with an interiorly wound up extension ll of the outer cylindrical portion 1. This construction provides an interiorly located condenser portion constructed in one piece, and is extremely efiective in practice.

The condenser 1 shown in Figs. 6 and 7, is similar to Figs. 2, 3, 4 and 5, in that it combines the two perforated end caps 8-8, upon the ends of a dual wound up structure comprising a sheet of fine metal mesh 12 and a piece of cloth-like woven glass textile l3, the outer cylindrical section I being of the mesh and the inner portion of the condenser being arranged with alternate rolled sections of metal mesh l2 and glass textile l3, as seen in Fig. 7. The fibres or the 55 woven glass textile are so fine, as to increase the capillary retention capacity of the condenser.

By referring to Fig. 1, it will be noted that while the condenser fits the holder bore I! rather snugly, the end of the condenser extending into the bore I 5' of the stem 2 is cleared all round into the pipe bowl B, by reason of the bore 15' being larger than the diameter of the condenser. This forms a draft passage all around the cylindrical condenser, so that, with the inner located draft bore 9. as a supplemental opening, smoke is passed through the condenser interior, at its inner end through its longitudinal, cylindrical exterior and thence to the bore of the stem 3. This causes the passing smoke to become widely disseminated through the condenser in its passage to the mouth of the smoker, and effectively condenses out the products of distillation.

Thus, the arrangement as set forth above provides for an amplified distillate condensing area in a relatively restricted draft bore, which is extremely effective for the purpose desired.

It is to be further noted that the inner one of the caps 8 has an added function of acting as a diverting baiiie for the smoke passing from the bowl B into the condenser.

Other non-absorbent materials may be used of non-vegetable or non-animal fibres such as for instance, shredded and woven or unwoven asbestos, as a substitute for the glass cloth herein noted.

Having thus described the invention what is claimed is:

l. A pipe or the like having a bowl, a mouthpiece, a condenser comprising layers of glass fabric and a passage between the bowl and substantially all of the outer surface of the condenser and a passage between the mouthpiece and the interior of the condenser.

2. A smoker's device having a smoke passage and contained therein a condenser containing alternate layers of wire mesh and glass textile and a communicating passage between the interior of the condenser and one end of the smoke passage and another communicating passage between substantially all of the exterior of the condenser and the other end of the smoke passage.

' 3. In combination, a pipe having a bore communicating with the bowl; a condenser cartridge in said bore substantially in spaced relation with the bore to form a draft passage around the cartridge; said cartridge comprising filter material surrounding an axial passage; a bit communicating with said axial passage and a cartridge holder associated with the bit so as to prevent smoke from entering the bit except through the axial passage; whereby smoke passes from said draft passage transversely through the material into the axial passage and then into the bit; and said cartridge having an opening at each end thereof.

4. In combination, a pipe having a bore communicating with the bowl; a tubular cartridge holder having an intermediate annular flange engaging the outer end of the stem, a longitudinally split resilient cylindrical inner portion frictionally engaged in said bore, and a knurled outer end; a bit molded on the knurled outer end against said flange and communicating with the interior of the holder; and a condenser cartridge frictionally received in said split portion and extending substantially to said bowl in spaced relation with the bore to form a draft passage around the cartridge; said condenser cartridge containing layers of glass fabric and having a small axial passage communicating with the interior of the cartridge holder; the layers of glass fabric being held in place by a cap having a perforation aligned with the axial passage.

5. A pipe or the like having a bowl, a mouthpiece, a condenser comprising layers of glass fabric and an axial passage small enough to cause contact of the smoke with the edges of the fabric, a passage between the bowl and substantially all of the outer surface of the condenser and a passage between the mouthpiece and the interior of the condenser.
