John C. Emhardt, Orange, Conn., assignor to Sidney Blumenthal & 00., Inc., New York, N. 1., a. corporation of New York Application February 2, 1934, Serial No. 709,442 In Canada January 13, 1933 v 7 Claims. This invention relates to the method of prolayer and-a resilient rubber layer secured directly to .each other.
An object consists in providing such a method in which the rubber is applied to the fabric in such a manner as not to injuriously affect the latter in any respect; and in which the cellular quality of the rubber is produced by boiling of a liquid medium with which the rubber is mixed or in which it is suspended or dispersed.
A practical embodiment of a materialmade in accordance with the method to be described is shown in the drawing, in which Fig. 1 represents a detail plan view, partly broken away;
Fig. 2 represents a detail bottom view; and Fig. 3 represents a detail section taken in the plane of the line- IIIIII of Fig. 2, looking in.
the direction of the arrows.
In the drawing, the fabric layer is represented as V -pile fabric, in which the pile threads are denoted by l, the warp threads by 2, and the weft threads by 3. This fabric may be of any well known or approved specifications as to material and weave; and, as the said specifications constitute no part of this invention, and many embodiments thereof are well known to operators skilled in the industry, they will not be here detailed.
The rubber layer is marked 3. It may preferably be composed of a concentrated aqueous dispersion of rubber, such as natural or artificial latex, mixed with suitable modifying and vulcanizing ingredients, and including a small amount of added water, such a composition being adapted to be vulcanized in place on the pile fabric. The mixture may include also a filler, such as chalk; and it should be refined by filtering through a wire mesh before applying to the fabric. v p A preferred manner of practising this method is to weave, dye, and finish the pile fabric as desired. The aqueous dispersion of rubber is mixed with the suitable modifying and vulcanizing agents, as above indicated, the dry ingredients being sifted into the liquid during mixing, and the said mixture is applied to the back of the pile fabric by the use of ,a doctor blade. In performing this step, the blade may be set at (C1. Ell- 70) 'a predetermined distance above the surface of a ducing a floor co ering which comprises a fibrous table or the like, the fabric passed along the table underneath the blade, and a supply of the rubber mixture applied to the fabric adjacent the blade in order to cause the latter to spread it evenly and at a desired thickness on the back.
applied, in suitable thickness, to the back of the pile fabric, the material is promptly led into a heated chamber or the like. The temperature of this chamber is above the boiling point of water and may preferably be between 220 F. and 300 F. A temperature of 250 F. has been found satisfactory. v
The effect of this heat upon the Water constituent of the aqueous dispersion of rubber, together with such-water as may have been added, is to cause it to boil and thereby impart a somewhat cellular quality to the rubber. Likewise the heat solidifies and'vulcanizes the rubber so as to bring it to a tough resilient condition and to effect firm union between the rubber layer and the pile fabric, as indicated in Fig. 3 of the drawing. It has been found that, with a suitable mixture including a vulcanizing agent and an accelerator, a treatment forforty-five minutes at a temperature of 250 F.'is satisfactory for producing the cellular quality of the rubber, vulcanizing it, and bringing about firm adherence between'it and the fabric. At the end of this period, the fabric, with its rubber backing, may be led from the vulcanizing chamber, finished in any desired manner, and stored or otherwise disposed of.-
It will be observed that this invention does not require the employment of added chemicals for the generation of gas or the like, but that it relies upon the boiling of the water present in the mixture in which the rubber is dispersed for the purpose of imparting the bubbly or cellular characteristic to the rubber. It will be observed particularlythat this method does not contemplate the production of a layer of rubber separate from we a.
after the application of the mixture to the fabric.
As a Specific example of thecharacter of mixture which has been found advantageous in practising the method set forth, a typical formula may be given as follows: I
It will generally be desirable to refine the mixture by filtering through a wire mesh, after which it is ready to be spread on the fabric material, as above'described. The compound just set forth may be spread on the fabric in a thickness of approximately 0.03 inch, and such a coating will be completely dried and cured if allowed to remain in the drier forty-five minutes at a temperature of 250 F., as above noted.
This method is very simple and inexpensive, and the material produced is highly desirable for use as a floor covering and the like, particularly from the view-points of appearance, durability, resiliency and non-slipping.
This application is a continuation in part of John C. Emhardts application, Serial No, 630,000
filed August 23, 1932.
It will be understood that various changes may be resorted to in the materials employed and the steps followed, without departing from the spirit and scope of this invention; and hence I do not intend to be limited to the details herein shown and described, except as they may be included in the claims.
What I claim is:

' fabric with the rubber mixture; and subjecting providing a plastic vulcanizable mixture of concentrated rubber latex; coating one face of the the coated fabric to a temperature sufficient to boil the water in the rubber mixture; said rubber mixture comprising substantially 133 parts "by weight of concentrated latex, 2 parts of sulphur,
7 parts of zinc oxide, parts of chalk, together with an antioxidant, an accelerator, a stabilizer, and a small quantity of added water.
2. 'A method ofproducing a floor covering or the like which comprises the steps'of providing a I aoeavaa tion and cellular characteristic are brought aboutflcient time to cure and dry the rubber,
