Description

UNITED STATES E. E. MARGY, OF NEW YORK, Y.

IMPROVEMENT IN INDIA-RUBBER FABRICS.

Specification forming part of Letters Patent No. 26,359. dated December 6, 1859.

To all whom it may concern:

Be it known that I, E. E. MARGY, of the city of New York, in the State of New York, have invented a new and improved fabric or compound of india-rubber which will cause it to retain permanent elasticity and withstand changes of temperature and emit-no unpleasant odor; and I declare that the following is a true description of the same.

The nature of my invention consists in producing a new fabric by the combinationof sulphuret of lead and carbonate of lead with india-rubber or caoutchouc and submitting the compound thus formed to the action of heat. I combine these articles with india-rubber'in the following proportions, which are the best known to me, although they may be varied with good results.

To two parts of rubber I add one part of sulphuret of lead and one part of carbonate of lead, by weight, and mix or unite the compound by passing the same through the heated rollers or grinders now generally used in preparing and manufacturing india-rubber. After the mixture is thoroughly combined by grinding it may be spread upon cloth or rolled into sheets, or put into any other required form for use. It shall then be subjected to the action of steam or water at a high temperature by being placed in a vessel containing steam at a heat from 240 to 350 Fahrenheit, or containing water, or containing water and steam at the same high temperature.

It may be necessary for the thorough ourin g of some articles, to increase the temperatura to 400 and upward but the degree of temperature and the length of time that the compound must be submitted to the heat will depend to a certain extent upon the size and quality of the fabric; but the heat will in no case be carried so high as to liberate sulphur from the sulphuret of lead.

The application of heat by means of steam Q or hot water may be made by any of the wellknown processes in the manufacture of indiarubber, and must be made by such means as the compound will not cure satisfactorily in dry air.

French chalk or paris-white may be added to the compound for the purpose of increasing the bulk of the compound, and plaster-of-paris for the purpose of hardening it may be added in small quantities.

Other ingredients may also be added for the purpose of coloring the fabric or giving it peculiar properties, as is well known to indiarubber manufacturers but such articles have no effect in producing the result I have described.

I have sometimes dispensed with the carbon- .quantity of protoxide of lead or litharge and chalk, with the addition of some of the abovenamed substances, for the purpose of giving body and color to the fabric with a good result.

I do not claim the process of Charles Goodyear as set forth in his original patent of June 14, 1844, and reissued December 25, 1849; nor the curing of india-rubber as set forth inpatent of S. Monlton, August, 1847, (English 5) but What I do claim as my invention, and desire to secure by Letters Patent, is-

The improved india-rubber fabric made by the combination of india-rubber with sulphate of lead and carbonate of lead or the protoxide of lead, and by the exposure of said compound to steam or water at the temperature herein-. before stated,substantially as described,without any admixture of free sulphur.

E. E. MAROY.
