UNITED STATES PATENT OFFICE.
WILSON H. STRIGKLER, OF COLUMBUS, OHIO.
HEAT-RESISTING VULCANIZED FABRIC} No Drawing.
Specification of Letters Patent.
Patented Dec. 31, 1912.
Application filed December 14, 1911.. Serial No. 665,790.
in connection with theater curtains, screens,
or other articles in which a flexible heat resisting fabric is desirable.
The invention consists of a pliable fabric saturated with a rubber solution in which is thoroughly incorporated a suitable aluminate and finely ground or pulverized asbestos, said solution being applied to either one or both sides of the fabric. It will be understood however, that the said solution is not simply a coating for the fabric but is thoroughly incorporated into it under suitable pressure, and further subjected to a high temperature, so that the fabric and the rubber solution with the aluminate and the asbestos become practically one article.
In order that the said invention may be more fully understood a brief description of the manner in which it is prepared is hereby given.
' The fabric which may be of duck, canvas or any other suitable fabric is'treated either .upon one or both sides by a solution of liquid rubber, to which has been added equal amounts of commercial aluminate, a mlca preparation, and pulverized asbestos.
The term aluminate is a trade name employed to designate a certain mica preparation which I have found by careful exeriments to be superior for the purpose I intended than any other micapreparation I have been able to obtain. Thls term designates the finest ground mica put out and is also known as commercial silicate of alumina, the word aluminate designating as before stated the product of a particular company.
The rubber solution is obtained by reducing the rubber to small pieces and then applying a suitable solvent, such as benzole same has been applied to the fabric the.
or bisulfid of carbon, the former being preferred.
The oombinedmixture has a consistency about equal to that of cream and after the latter is passed between rolls so that the solution is tho-roughly incorporated with the fibers of the fabric. I have foundv that where a rubber solution alone is employed a tacky quality is givento the fabric. This fabric, however, lacks a heat resisting quality which I desire to obtain in combination with the tackiness above mentioned. The
the amount of asbestos is reduced to onethird instead of one-half. The fabric is then subjected to a heat of about 275 degrees F. for about thirty minutes which cures or vulcanizes it, it is then ready for use. The solution above mentioned may be applied to a clean fabric, or to 'a fabric which had previously been treated with rubber, or it can be applied to a sheet of rubber, which would replace the textile fabric.
The advantage gained by charging a textile base with a rubber solution carrying powdered mica and powdered asbestos consists in the fact that when these materials are brought into close combination with the fabric and. are incorporated into the meshes and fiber of the fabric, they impart to the fabric after being thus incorporated their own distinctive qualities of heat resistance, making the fiber heat resistant when thus treated. Theadvantage of employing both the mica preparation and the asbestos has been fully pointed out and also the fact that -with a solution of rubber to which has been added a finely ground preparation of mica andpulverized asbestos.
H 3'. A heat resisting ifabric consistingLof a textile .base, and a rubber solution incorporated in said base, saidqsolution having incorporated therein a suitable mica preparation and pulverized asbestos.
4:- A heat resisting fabric consisting of a textile base, and a rubber solution incorporated in saidbase and vulcanized thereto, said solution being treated with a finely ground mica preparation and pulverized asbestos prior to application of the solution to said base. I
5. As a new article of manufacture a base of textile fabric, a rubber solution having comminuted asbestos and a finely ground mica preparation incorporated therein, said rubber solution being pressed into the meshes of said fabric and thoroughly incorporated 15 With the fibers of said fabric.
