To all whom it may concern:

Be it known that I, RICHARD JESCHKE, a citizen of the German Empire, and resident of Charlottenburg, in the State of Prussia, German Empire, have invented new and useful Improvements in Flooring Materials.

and Processes for Making Same, of which the following is a full,clear, and'exact speci- I realize a remarkable economy when com pared with the usual products. Further, my

product has the advantage that it is immediately ready for use and does not want as linoleum does, storing for a rather long period and drying, time, storing rooms and drying appliances being thus dispensed with. My new product is very tough and flexible or elastic, so that it is not necessary to apply it to a lining of textile fabrics, paper or the like as is necessary in the case of linoleum. However, if desired, such a lining canof course be used;

- Accordin to my invention I first prepare two ingredlents, viz: (1) the rubber-like product obtained by heatingglue or other glutinous substances or carbon hydrates with glycerin and (2) artificial resins prepared by acting upon phenols and formaldehyde with alkaline condensing agents, such as caustic alkalis or alkali carbonates. I then mix these ingredients and heat the mixture until a tough mass is formed. While heating, a certain quantity of formaldehyde that has not entered the reaction, acts as a hardening agent. Other hardeningagents such as chromium salts, alum,"tannin' or the like may be added if desired, care being taken however in all cases to ensure a sufiicient elasticity of the product.

The productthus obtained can then be treated in the manner known'in connection with linoleum by mixing it with cork meal v and kneading and'rolling the mixture in the manner'well known to those skilled in the art. For cork meal I can substitute partly new product is distinguished from.

or wholly other filling agents, such as wood meal or other finely disintegrated cellulose.

If it is desired to obtain a coloured product, pigments 'may be added to the mixture. If desired, the mass can be rolled upon a lining of paper or textile fabric but, as already mentioned, such lining is not absolutely necessary.

For the glycerin used in preparing the first ingredient above referred to, other substances which are hygroscopic or prevent the mixture from drying may be substituted such substances being for instance potassium sulfocyanate which may be-usedas an aqueous solution. I

-In practically carrying out-my process I can for instance proceed as follows:

Example: I first prepare the two ingredients of the mixture. 200 grammes of glue or gelatine are allowed to swell ii -water and heated with 450 grammes of glycerin for about 15 minutes ,up to about 90 C.

On the other band, 300 grammes of phenol bonate or the corresponding quantity of so- I dium carbonate or caustic soda solution for about 10,1ninutes up to about 100 C. The artificial resin thus obtained is mixed with'equal'parts' of the mass obtained from glue and glycerin and the mixtureis heated until a tough viscous mass is obtained. During this heating a certain quantity of formaldehyde that has not entered the'reaction, acts. to hardenthe product.

" Instead of'carbolic acid other phenols,

creosote or the likemay be used.

I then take-18 parts by weight of the mass -so' obtained and Ilmix tliem with 18 parts of cork meal or wood meal and if desired with 12 parts'ofalpulverized pigment. The

pastous mass thus obtained is then kneaded and rolled inthe well-known manner.

. The proportions indicated may be modified according to the requirements of the special case and to the pro erties desired of the roduct to be obtalne ving thus described myinvention I wish it to be understood that I do not desir'e to limit myself to the exact details and proportions given, as obvious modifications will occur to persons skilled in the art What I claim is 1. The process of manufacturing linoleumduring the last densing a phenol with formaldehyde by means of an alkaline condensing, agent, heating the mixture until a tough mass is formed, adding a filling agent, and kneading and rolling the mixture thus obtained.

2. The process of manufacturing linoleumlike material, which process consists in mix-4 ing the following two ingredients, viz the product obtained by heating glycerin with an organic compound, capable of forming a rubber-like product-by acting on glycerin, for producing therewith a rubber like product, and an artificial resin obtained by condensing a phenol with formaldehyde bymeans of an alkaline condensing agent, heating the mixture until a tough'mass is formed, adding a hardening agent during the last part of the heating process, then adding a filling agent, and kneading and rolling the mixture thus obtained.

3. The process of manufacturing linoleumlike material, which process consists in mixing the following two ingredients, viz the product obtained by heating glycerin with a glutinous substance, and an artificial resin obtained by condensing a phenol with formaldehyde by means of an alkaline condensing agent, heating the mixture until a tough mass is formed, adding a filling agent, and kneading and rolling the mixture thus obtained.

4. The process of manufacturing linoleumlike material, which process consists in mixing the following two ingredients, viz the product obtainedby heating glycerin with a glutinous substance, and an artificial resin obtained by condensing a phenol with formaldehyde by means .of an alkaline condensing agent, heating the mixture until a tough mass is formed, adding a hardening agent art of the heating process, then adding a lling agent, and kneading and rolling the mixture thus obtained.

5. The process of manufacturing linoleumlike material, which process consists in mixing equal arts by weight of the following two ingre ients, viz the product '-0bta1ned by allowing 200 grammes of gelatine to swell in water and heating them with 450 grammes of glycerin up to about 90 C. for about 15 minutes, and the artificial resin obtained by heatlng 300 grammes of phenol with 300 grammes of a 35 per cent formaldehyde solution and 50 grammes of potassium carbonate up to about 100 C. for about 10 minutes, heating the mixture of these two ingredients until a tough viscous mass is formed, mixing 18 parts by weight of this mass with about 18 parts by weight of cork meal and about 12 parts by weight of a pulverized pigment and kneading and rolling the mixture thus obtained.

6. The herein described linoleum-like composition consisting of a mixture of 200 grammes of gelatine with 450 grammes of glycerin and an artificial resin prepared from 300 grammes of phenol and 300 rammes of a 35 per cent formaldehyde soution and 50 grammes of potassium carbonate with an equal Weight of cork meal.

7 The herein described linoleum-like composition consisting of a mixture of 200 grammes of gelatine with 450 grammes of glycerin and an artificial resin prepared from 300 grammes of phenol and 300 grammes of a 35 per cent formaldehyde solution and 50 grammes potassium carbonate with an equal weight of cork meal and approximately two-thirds of its Weight of a pulverized pigment.

8. The herein described linoleum-like comproduct obtained by heating glycerin with an organic compound, capable of forming a rubber-like product by acting on'glycerin,

for producing therewith a rubber-like product, and an artificial resin obtained by condensing a phenol with formaldehyde by means of an alkaline condensing agent, heating the mixture until a tough mass is formed, adding a filling agent, and kneading and rolling the mixture thus obtained.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
