ATTO YS Patented Nov. 10, 1936 'PATENT OFFICE SANITATION SYSTEM FOR METALLIC BUILDING STRUCTURES Thomas V. Balch, Shaker Heights, Ohio, vassigner to The E. F.Hauserman Company, Cleveland, Ohio, a corporation of Ohio Application January 4, 1934, Serial No. 705,298
8\Claims. (Cl. 18S-85) This invention is a system of sanitation for metallic wall structures, such as partitions, doors, trim and the like, of hollow metal construction which provides a treatment to inhibit and destroy animal and vegetable organisms on the exposed surfaces, in the crevices, joints and interior hollow portions, as well as in the comparative soft materials used for fillers and insulation and the like.
10 The system provides a treatment which is enduring, harmless to human beings, odorless and is not destroyed-by steam baths or other materials used in fumigating, disinfecting or cleaning in the vicinity of the structure.
l5 It further provides a treatment for exposed surfaces in the same manner, in as much as the finishes usually extend continuously into the joints and it is not generally practical to provide a line of demarcation between parts which would be concealed and parts which will be exposed in the final assembly, as it is preferable lto have the highly-reflned finished surfaces of exterior parts extend behind retaining members in many cases with an adjustable fit.
To the accomplishment of the foregoing and related ends, the invention, then, consists of the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain embodiments of the invention, such being illustrative however, of only a few of the various ways in which the principle of the invention may be employed.
In said annexed drawing:/
The sole figure is a fragmentary perspective view illustrating an embodiment of the invention.-
It is well known that lithopone paints have the property of inhibiting the growth of vegetable organisms, largely due to the presence of zinc 40 oxide. There is also present in such paints a considerable quantity of barium carbonate. I Such paints have been unsuccessful as insecticides however.
The salts of hydro-uoric acid are particularly effective in destroying and inhibiting a growth of animal organisms even when these salts are present on dry surfaces in very minute quantities. Unfortunatelymost of these salts are highly corrosive and cannot be used in proximity to steel or on steel surfaces, for this reason. L`
' Barium fluo-silicate, also known as barium silico fluoride, is comparatively inert, however, and yet has a. great value as an insecticide, even in low concentrations. Precautions must be taken,
however, to have an excess of barium present in `be minimized.
For such reasons then, a proper sanitary finish on metal partition surfaces and the like has not 5 heretofore been had. By the present invention however, such surfaces may be effectively pro-- tected. e
In proceeding in accordance with the invention,
I prefer to use barium fluo-silicate combined with 10 a'lithopone base baking enamel to cover all metal surfaces inside and out. This provides an excellent protection to the metal which will stand up under considerable wear and many chemical exposures and will serve as an excellent ground 15 coat for the application of additional finishing coats on exposed surfaces. lThe barium carbonate present in lithopone provides the necessary excess of barium to prevent the coating from having a corrosive action. In order that the paint 20 may bake out toa smooth surface, I grind barium fluo-silicate together with the other solids in the pigment using one of the methods common in the manufacture of paint. I incorporate the barium fluo-silicate in a proportion of at least one-quar- 2 ter pound to the gallon and thepaint is then applied by any of the usual methods such as spraying, brushing, dipping, etc., and baked on if required.
When graining is applied to exposed surfaces 30 in order to simulate wood, vthis is generally done by the application of ink over the ground coating either manually, using brushes and combs or by process graining or by transfer. ISimilarly, various antiqued or stippled effects may be applied 35 over the ground coating. The final wearing suri faces of any of these treatments are then applied and are usually colorless baked varnish or clear pyroxylin lacquer. I employ barium fluo-silicate by 'grinding it into the lacquer or varnish in a 40 proportion of 4 oz. to the gallon and find that this does not affect the transparency, luster, gloss or wearing qualities while it does provide a germicidal treatment.
A colored finish maybe built up on the ground 45 coat by the use 'of baking enamels or pigmented' lacquers, in which case the'nishing coat is likewise treated by` grinding barium fluo-silicate therein in'a proportion of 4 oz. to the gallon.
Where soft materials such as building boards, 50 acoustical treatment and the like are used either internally or externally, these are best used in the form of composition boards such as the various pulp building boards although cork is equally suitable. 4 These are usually glued to steel sheets 55 using a form of modified silica glue, although in cases some of the albumen glues are employed. I prefer to use the silica type of glue in which is mixed barium silico fluoride in a proportion of one-half pound to the gallon and to thoroughly coat the edges of the composition board with the glue in the instances Where steel sheets are glued to either side of the board. Where the steel sheet is glued to only one side of the board, as in partitions having double insulated panels with an air space between, the unglued side of the composition board is treated with a light spray coat of barium silico fluoride mixed in any medium which will serve as a binder such as wall size or the same glue as is commonly used on the opposite side.
In like manner, any loose materials such as mineral wool, balsam wool and the like may be treated with barium fluo-silicate using any type of paint, or such materials may be encased between paper in quilts or stockings and the paper treated with the barium nuo-silicate.
It will thus be seen that a system is provided which furnishes a protective coating on all parts of the metal and which will not develop any corrosive action. Correspondingly, a further treatment is built up on the exposed surfaces without in any way detracting from the wearing qualities or appearance of the surface.V Likewise, any interior fillers are treated in such a manner as to effectively hold the insecticide and germicide permanently in position.
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the means stated in any of the following claims, or the equivalent of such, be employed.
I therefore particularly point out and distinctly claim as my inventionz- 1. A sanitary coated building structure, comprising abuilding structure element including steel surfaces having a hardened organic paintlike coating applied to the steel surfaces, and a non-corroding fluoride embodied in such coating.
2. A sanitary coated'building structure, comprising a building structure element including steel surfaces and fibrous materials and having a hardened organic paint-like coating with an admixed non-corroding fluoride on the metal surfaces and a non-corroding fluoride held in contact with the surfaces of the fibrous materials by a mixture in a binder.
3. A sanitary coated building structure, comprising a building structure element including steel surfaces having a hardened Organic paintlike coating applied to' the steel and barium fluosilicate embodied in such coating.
4. A sanitary coated building structure, comprising a building structure element including steel surfaces and brous materials and having a hardened organic paint-like coating with admixed barium fluo-silicate on the metal surfaces and barium nuo-silicate held in contact with the surfaces of the fibrous materials by a mixture in a binder.
5. A sanitary coated building structure, comprising a building structure element having a hardened lithopone-base organic coating applied to the bare steel and a non-corroding fluoride embodied in such coating.
6. A sanitary coated building structure, comprising a building structure element including steel surfaces and fibrous materials and having a hardened lithopone-base organic coating with admixed non-corroding fiuoride on the metal surfaces, and an inert fiuoride held in contact with the surfaces of the fibrous materials by a. mixture in a binder.
7. A sanitary coated building structure, comprising a building structure element including steel surfaces having a hardened lithopone-base organic coating applied to the steel, and barium fluo-silicate embodied in such coating.
8. A sanitary coated building structure, comprising a building structure element including steel surfaces and fibrous materials and having a hardened lithopone-base organic coating with admixed barium fluo-sicate on the metal surfaces, and barium fluo-silicate held in contact with the surfaces of the fibrous materials by a mixture in a binder.
