PROCESS OF SOLIDIFYING AND TOUGHENING OILS.

SPECIFICATION forming part of Letters Patent NO. 724,618, dated April 7, 1903.

Application filed November 4,1901.

To all whom it may concern:

Be it known that we, JOSEPH BAnToN'SoAM- MELL and Ennnsr ALFRED MUSKETT, subjects of the King of England, residing at London, England, have invented a certain new and useful Improved Process of Solidifying and Toughening Oils, (for which We have made application for Letters Patentin Great Britain, No. 21,229, dated October 23, 1901,) of which the following is a specification.

The present invention relates to a process for the treatment of oils, its object being to solidify and toughen oils and render them suitable for use as substitutes-for india-rubber, gutta-percha, or the like, or for admixture with these substances to reduce the cost of their manufacture.

In carrying out this invention any suitable animal or vegetable oil, such as castor-oil, is in the first place mixed witha certain proportion of some fibrous material, such as cotton, rhea, or any other form of cellulose. To this mixture is slowly added a solution of chlorid of sulfur in bisulfid of carbon or other solvent, the whole being vigorously agitated, and in a short time the mixture is found to solidify into a tough and perfectly homogeneous mass which can be used after suitable treatment-such as drying, grinding, or the like-in place of or mixed with indiarubber, guttapercha, or other similar materials.

In some cases it is found advantageous to reduce the cellulose before adding it to the oil by applying great heat to the cellulose in a closed vessel, thereby driving oi the volatile constituents and converting it into a gummy mass. The'cellulose in this form is then added to the oil.

In some cases it is also found desirable to add to the mixture described above a small percentage of some form of drier, such as oxids of calcium, magnesium, barium, &c.

The following proportions of the ingredients of the solidified oil according to this invention have been found to be suitable: Eight parts, by weight, of castor-oil; one part, by weight, of oxid of magnesia; onesixteenth part, by weight, of cotton fiber (or Serial No. 81,104. (No specimens.)

cellulose reduced by 'heat;) eight parts, by weight, of carbon bisulfid; one part, by weight, of chlorid of sulfur.

The solution of chlorid of sulfur in carbon bisulfid should be added slowly while the mass is thoroughly mixed. The proportion of cotton fiber or reduced cellulose mentioned above may be increased in some cases even up to two parts, by weight, these proportions depending on the special qualities required in the finished articlesuch as color, softness, &c.some amount of experiment being necessary to suit the method of manufacture to the special purpose for which the resulting product is required.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The process for solidifying and toughening oils which consists in adding to the oil a certain proportion of fibrous material, and thereafter stirring the mixture together with a solution of chlorid of sulfur until the fiber is completely dissolved whereby a tough and homogeneous mass is formed.

2. The process for solidifying and toughening oils which consists in adding to the oil a certain proportion of cellulose and thereafter stirring the mixture together with a solution of chlorid of sulfur until the fiber is completely dissolved wherebya tough and homogeneous mass is formed.

3. The process for solidifying and toughening oils which consists in adding to the oil a certain proportion of cellulose which has been reduced to a gummy mass by distillation in a closed vessel and thereafter stirring the mixture together with a solution of chlorid of sulfur whereby a (tough and homogeneous mass is formed.

i. The process for solidifying and toughening oils which consists in adding to the oil a certain proportion of cellulose which has been reduced to a gummy mass by distillation in a closed vessel, adding thereto a small percentage of someform of drier and thereafter stirring the mixture together with a solution of chlorid of sulfur whereby a tough and homogeneous mass is formed.

5. As a new article of manufacture oil which has been solidified and toughened by adding thereto a certain proportion of some fibrous material and thereafter agitating the mixture with a solution of chlorid of sulfur until the fiber is completely dissolved, whereby a tough and homogeneous mass is formed.

6. Asanewarticle'ofmanufactureoilwhich has been solidified and toughened by adding thereto a certain proportion of cellulose and thereafter stirring the mixture together with a solution of chlorid of sulfur until the fiber is completely dissolved wherebya tough and homogeneous mass is formed.

7. As a new article of manufacture oil which has been solidified and toughened by adding thereto a certain proportion of cellulose which has been reduced to a gummy mass by distillation in a closed vessel and thereafter stirring the mixture together with a solution of chlorid of sulfur wherebya tough and homogeneous mass is formed.

8. As a new article of manufacture oil which has been solidified and toughened by adding thereto a certain proportion of cellulose which has been reduced to a gummy mass by distillation in a closed vessel, adding thereto a small percentage of some form of drier, and thereafter stirring the mixture together with a solution of chlorid of sulfur wherebya tough and homogeneous mass is formed.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
