ANTISTATIC TILE AND METHOD OF MAKING Filed Oct. 1, 1952 npwmm w/@ INVENTOR. HARRY A.TOULM|N JR.
BYFM' 7 ATTORNEYS United States Patent ANTISTATIC TILE AND METHOD OF MAKING Harry A. Toulmin, Jr., Dayton, Ohio, assignor to The Commonwealth Engineering Company, Dayton, Ohio, a corporation of Ohio Application October 1, 1952, Serial No. 312,446
11 Claims. (Cl. 117-217) My invention relates to antistatic tile and the method of making.
It is the object of this invention to provide metallic coated ceramic resiliently supported tile, particularly a tile that will prevent the discharge of static electricity.
It is a further object of this invention to provide a resilient, non-combustible, non-inflammable, base for tile integrally connected therewith, and made a part'thereof, on which tile or resilient coating there is imposed a film of metal.
It is a further object to provide a continuous process for manufacturing such tile; and to provide an adhesive on the back of the supporting base so that the tile can be applied over very considerable size areas Without the necessity of handling of each particular tile.
Referring to the drawings, Figure 1 is an isometric perspective of the entire apparatus practicing the process.
Figure 2 is an isometric view, partially in section, showing the resulting product.
Figure 3 is an enlarged view in section, in an isometric view, illustrating the details of the tile.
Figure 4 is a section through the tile, illustrating a modification in which fine points are formed on the surface of the tile to facilitate the harmless discharge of static electricity.
It is a particular object of this invention to provide a tile for use in operating rooms, chemical plants and laboratories and other locations where the discharge of static electricity would be dangerous to property and lives. It has long been a problem in operating rooms and other similar places to prevent the explosion of gases being used in such enclosures, as in the case of operating rooms when anesthesia is being given. There has been no satisfactory way by which such static electricity can be prevented from setting off an explosion when using the present type of tiles.
Some progress has been made in this direction by the use of carbon-black, but the ditficulty has been that this reduces the light reflecting characteristics and the sanitary appearance and other characteristics desired in tile of this character.
Referring to the drawings in detail, 1 designates a roll of asbestor, rock wool, glass fiber, or other similar incombustible or non-inflammable, resilient fiber. This acts as an insulation mat to further prevent the storage of static electricity on the tile surface. 2 designates a sheet of such material as it is unrolled from the roll 1. 3 is a guide roller. This sheet 2 is guided to the top of the endless conveyor belt 4 mounted on rolls 5 and 6 and preferably suitably driven. The sheet 2 passes beneath the applicator for applying resilience to give body and form, particularly to the top area thereof, of the fibrous mat 2. This consists of a pipe 6 leading from a supply of resins. The material passes through the valve 7 and out of the nozzle 8 on to the surface of the fiber sheet 2 to impregnate it. This sheet then passes under the corrugated roller 9 which indents the surface of the 2,734,007 Patented Feb. 7, 1956 sheet with its plastic coating to form tile like indentations. The tile grooves are designated 9a.
This formed sheet now passes beneath the ceramic material applicator fed from the pipe 10 into the tank 11 and out the nozzle 12 where the ceramic material 13 is applied to the surface of the mat as it has been formed. If desired, a roller can be applied to force the ceramic material into the fiber and configurations of this fiber.
Ordinarily that is not necessary. Such a roller can be that as shown at 14. If desired, however, to provide the surface of the ceramic material with very fine points to facilitate the discharge of static electricity harrnlessly, then the surface of roller 14 is formed in a series of fine depressions so that similar projections will be formed on the surface of the ceramic material as the roller turns and sucks up the surface of the ceramic material in small points.
Thereafter, this composite sheet is passed to a combined baking oven and a gas plating oven 16 as the baking operation and the gas plating takes place simultaneously.
The gas plating that takes place is done by heating the work piece, such as the sheet passing through the oven 16, by using means such as gas dielectrics, high frequency, etc. The metal carbonyls or metal hydrides are supplied through the inlet pipe 17 and the surplus gases are removed through the pipe 18.
As a result of the rapid gas deposition of thin metal upon the moving sheet, the tile is coated with a thin film of nickel or other metallic film materials. If the small indentations have been made in the roll 14, then the plating will plate the projection 15a which act as static discharge points. If they are micron or sub-micron size, so that the problem of walking upon them or the problem of cleaning them is not prohibitive, then the result of anti-static is satisfactory and the tiles can be used in the ordinary manner. These fine points are hardly distinguishable by the naked eye. They do add an important additional advantage and that is that they prevent slipping of rubber shoes upon tile where a great many accidents take place. It is to be understood that there are a variety of ways by which the surface of the tile can be roughened in order to provide these fine projections. There is only one suggested herein as its possible for anyone skilled in the art to devise a variety of diiferent ways in which this basic object can be accomplished.
After the finish tile sheet emerges with its coating of metal 19, the underside is coated with adhesive 26 to facilitate the application of the resulting, composite sheet to some supporting surface such as a floor, a wall or ceiling. The pipe 20 supplies the resilient adhesive through the valve 22 controlled by the handle 21 that passes into the manifold 23 out the ports 24 in sprays 25. If this resin necessitates further drying for conversion, the sheet can be passed through a second oven in the usual manner.
It is to be understood that I desire to comprehend within the hereafter appended claims variations of structure and method to fairly comprehend them within their terms and within the scope of the invention as set forth hereinbefore.
