NICOTINE ABSORBER.

Application filed August as, 1921. Serial No. 496,421.

To all whom it may cancer n..-

Be it known that I, JOHN T. LINKLATER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Nicotine Absorbers; and I dohereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same;

This invention relates to a nicotine .absorberand particularly to such a device molded into cake form suitable to be received in the bowl of a smoking composed of absorbent material. s well known to all pipe smokers that objection-' able juices containing a large amount of nicotine collect in the bowl and. stem of a pipe and are ob'ectionable and distaseful to the smoker. he removal of these juices causes a great deal of inconvenience and necessitates emptying the pipe and often strikin the same about and b owing therethrou j It 1s an object of this invention to provide a device which can be laced in the bowl ofa pi e and into whic the tobacco.

will be place which device will completely absorb the nicotine and prevent the collecf tion of the said objectionable juices-or liquids and which-device is absolutely tasteless and does not in any way interfere with the smoking operation. Furthermore, with the use of the said device, the tobacco can be smoked to perfectly dry ash.

It is a further object of this invention to provide anovel process of making such a nicotine absorber.

These and other objects of the invention will now be fully set forth, reference being Fig. 3 is a bottom plan view of Fig. 2.

The device comprises a dried cake 4 of absorbent material molded to suitable shape to be received in the bowl of a smoking ipe 5.

In the form shown in the drawings, t e' device is semiellipsoidal in form which is the approximate form of most pi bowls. The said molded cake formed y mixing to d fil iie an V gether two parts of bicarbonate of soda, ten parts oi Portland cement, twenty parts of' plaster of Paris and one art of common table salt. to form a paste and from this paste the cakes are molded and subsequentl dried. The plaster of Paris.and the bicar onate of soda combine to form a porous light substance and the Portland cement acts as a binder and to give the necessary hardness. The salt is added to effect a quick setting of the mixture. It is well known that Portland cement after settingwill not soften in liquid b'ut remains hard and firm.

in the pipe and the tobacco placed on top of the same. The cakes are porous and for lutely dry and sanitary and it is unnecessary to be repeatedly engaged in removing objectionable liquids therefrom. One of the devices placed in a pipe lasts for quite a period and when the same becomes full charged with the nicotine and absorbed substances the same is thrown away and a" new cake placed in the pipe.

Water is adde to this mixture The device can be easily and inexpensively made and sold at a low price.

It will, of course, be understood that various changes may be made mthe form and also in the composition of thedevice within the ordinary ran e of equivalents,

without departing from t e scope of applicants invention, which, generally stated, consists in the matter shown and described and set forth {in the appended claims.

What is claimed is:

1. The process of producing .a nicotine absorbing device adapted to be placed in a pipe WhlCh consists in mixing together bicarbonate of soda,.Portland'cement, plaster of Paris and common salt substantially in the pro ortions of 2, 10, 20 and 1, respectively, t en addin water to said mixture to form a paste, mol ing said paste into cakes in a form adapted to be received in a bowl of a tobacco pipe permitting the material forming said ca es to set, and thendrying the same. 1 p

'2. A nicotine 7 absorbing device com ris-' ing a molded and dried cake" of absor nt material adapted to be received in the bowi I 70 I The device, when dried, is merely placed of a. smoking ipe, said'material containing bicarbonate o soda and plaster of Paris.

3. A nicotine absorbing device com rising a molded and'dried cake of absor ent material adapted to be received in the bowl of a smoking pipe and formed of a mixture of bicarbonate of soda, plaster of Paris and Portland cement.- 1 A 7 4.- A nicotine absorbing device comprising amolded and driedcake of absorbent material adapted to be received in the bowl of a smoking pipe, said material being formed of bicarbonate of soda, Portland cement, plas-' ter of Paris and common salt.

5. The device set forth in claim 4, the materials being in the pro ortions of two parts of bicarbonate of so a, ten parts of Portland cement, twenty parts of laster of Paris, and one part of common tab e salt.

In testimony whereof I aflix my signature.

JOHN T. LINKLATER.
