JACQUES PERL, OF BERLIN, GERMANY.

TOBACCO PIPE, CIGAR, CIGARETTE, OR HOLDER THEREFOR.

- Application tlled Ileeember 29., 1921. Serial No. 525,759.

To all whom it may concern.:

lle it known that l, JACQUES Piani., a citizen of Germany, and a resident of Berlin. Germanv, have invented certain new and useful mprovcnu-nts lich-.ting to Tobacco Pipes. Cigars, Cigarettes, or Holders Therefor. of which the. following is a specification.

This invention relates to tobacco pipes. cigars, cigarettes or holders therefor Vand hrs for its object to provide. for more efiicient. cooling of the smoke. the absorption ot"A moisture or aqueous \.\pour and the retention of any heavier volatile substances entrained thereby, the unpleasantness o which is particularly noticeable when ythe tobacco is nearing final combustion, especially iu the case of short-stem tobacco pipes.

lleretofore attempts have been made to cool'the smoke by filtration or in cooling chambers or the deleterious substances in tne smoke have been absorbed or neutralized by the. chemical action of substances carried by o. suitable porous carrier. A

According to the present invention, the water vapour or steam generated during the combustion of the tobacco is utilized to cool the smoke by causing the products of' combu=tion of the tobacco to come in contact with salts which combine with water and in so doing absorb a comparatively large amount of heat. Such salts may be those used, for example, in refrigerating mixtures whose action also depends on the absorption of heat when dissolved. The salts should not however be volatile or give oft` any volatile noxious o1" unpalatable substances or be of too hygroscopic a miture.

For the purpose of the invention, Jthe salts employcdmay, for example, be crystallized y such as granulated carbon.

sodium acetate, sodinm sulphate (or Glanbers salt), ammonium nitrate or tli e like.

The salts are preferably interposed in suitable forni in the smoke. current, such as` for example, in the form of a plug or cartridge inserted in the pipe stem. Preferably the salts are mixed with or incorporated in an excess of highly porous substance, silica. (or kieseluhr), pumice-stone, blotting qpaper, or the. ke, in Order to provide a sin iciently large area in contact with the smoke.

Such cartridges may also be employed in cigar or cigarette tips. mouthpeces or holders.

Experiments with the artificial production of smol-:e by means of a jet pump have shown that b v the nse of a cartridge containing 3 grams of a mixture. of sodium acetate andA granulated wood charcoal in the proportion of one to three, the maximum temperature of the smoke from a short-stem tobacco pipe in the first test was-reduced by 9 degrees and on a second test using the Sallie substance again, the temperature was reduced by 7 degrees (centigrade).

As the temperatures in question vary slightly above blood heat, and the temperature. of the smoke may exceed 40 C., the enjoyment. and pleasantness of the smoke is considerably enhanced by such reduction of the temperature as that above quoted.

T he use of these salts has also the further advantage that the retention and cooling of the greater part of the moisture effects the. retention of a greater part. of the tarry volatile substances of higher boiling point entrained with the moisture, -thus improving the palatabilitv and enjoyment of the tobacco smoke. n addition, the tobacco and particularly the unconsumed residue in the pipe bowi is kept dry by reason of the moisture or condeusates being prevented from returning along the stem to the bowl. (on sequently more ellicient tobacco consumption is attained than heretofore usual, as frequently 15 to 20% of the tobacco was heretofore wasted.

The plugs or cartridges may be of rarious sizes and shapes to suit different tobacco pipes. The mixture contained in the cartridge may be obtained by simply mingling the porous substance with the salt or the poroussubstance may be impregnated with a solution ot" the. salt and the latter thereafter crystallized on the porou.c substance. In the case of cigar and cigarette tips or mouthpieces, the plug or cartridge may be oi' conical shape. Such paper tips or monthpieces may also be used as nxonthpieces for small pipe bowls.

'Ihe plug or cartridge mav consist of an outer prefe ably porous or {'mforated envelope through which the st ioke may percolate with or without perforated or porous ends, the eartrilge being filled with the salt or mixturel hereinbefore described.

The accompanying drawing illustrates one embodiment of my invention by way of example.

Fig. 1 is a side view of a cartridge made according to this invention. Figs. .2 a 1d 3 are opposite. end views thereof. Fig. 4 i5 a zdf:

longitudinali sectional view of the cartridge.

In the construction shown, the salt which cilects the cooling of the tobacco smoke is carried by a cartridge made of porous paper rolled to the shape shown and impregnated will a :..olution of the salt. My invention is not however limited to the use oi the cartridge shown.

It is to be understood that the term refrigcrating substance in the appended claims is to be construed as excludingr salta which absorb only a limited amount of heat from tle solvent during passage into solution and that the terni refrgerating sub? stance" therefore excludes common salt which absorbs only about 18 calories per grani of solvent and which it has already been suggested to useI in the bowl of a. to-

bacco pipe for absorbing or nicotinic, but not for cooling smoke.

Claims:

1. As an article of nnuuifacture, an absorption device for cooling tobacco smoke and adapted to be placed in the smoke path of a smoking' device, comprising sodium acetate and a porous -arricr therefor.

2. As an article of lnainifacturc, a cartridge for cooling tobacco smoke comprising a porous carrier in'ipregnatcd with a refrigcrating: substance capa-ble of absorbing heat when dissolved in water.

In 'testimony whereof I hereunto aflix my signature.
