SURFACE COVERING.

Specification of Letters Patent.

Patented July 10, 1906.

- which the following is a specification, reference being had therein to the accompanying drawin s, forming part of this specification, in whic Y Figure 1 is a face view of a surface provided with my improved covering or coating,

. portions of the successive layers being broken away to illustrate the process of application. Fig. 2 is a sectional view on the line II II of Fig. 1.

My invention relates to the art of applying an impervious lining or covering facing to the interior or exterior or both surfaces of boxes, vessels, or other inclosing structures or to surfaces of any kind Wherever a hard waterproof coating or covering is desirable.

In carrying out my invention I first apply a preliminary coating of a suitable material which will adhere to the surface to be coveredas, for instance, woodand which will serve as a primary base into which may be embedded a secondary holding-coating, upon which the final coating or covering may be laid, as hereinafter described. The several in redients employed, as hereinafter describe are well adapted for these purposes and in practice have given good results.

The invention is particularly applicable to the covering of the surfaces, either interior or exterior, or both, of rough boxes for caskets, although it may be applied to any other purpose, as for the lining of refrigerators, wainscoting of bath-rooms, laundries, &c.

In carrying out my invention I first apply to the surface 2 of the wood or other material a primary layer of suitable holding material consisting of pitch and asphaltum or tar and asphaltum, which may be applied to the surface in melted form by a brush or mop or in any other suitable manner. The object in using the asphaltum with the tar or pitch is to provide a sufficient body to retain the next or secondary layer of rough holding material,

which consists of fine gravel or sand or other suitable material 4, thickly sprinkled over the primary coatin 3. The gravel or sand may be applied whi e the first coating is still in semiliquid or plastic form, but is preferably applied in a hot condition, so that it will become embedded in the tar and asphaltum mixture, bein thereby rigidly set, so as to present a roug bondingor retaining surface having a firm engagement with the first layer or coating 3, Which has become strongly incorporated with the pores or interstices of the woodor other surface. Upon this rough layer 4 I apply the final outside coating 5 in one or more layers in the same general man ner as mortar is laid on by a trowel.

While various ingredients or materials may be used with more or less successful results, I

refer to use a mixture composed of a cement nown as Ke'enes cement, white sand,

marble-dust, pulverized oyster-shells, oxid of zinc, cream of tartar, and Water.

The sand, cement, and water form a stron durable composition. The marble-dust an powdered oyster-shells, or either of them, give a smooth finished surface. The cream of tartar acts to keep the mixture somewhat soft and plastic during an appreciable period, thus facilitating ornamentationof the surface by imprintin or molding it in any. suitable manner, w 'e the oxid of zinc acts to finally harden and petrify the entire surface of the composition.

I have found that where it is desirable to secure a highly-finished exterior surface a first layer or coating of the Keenes cement, white sand, and water mixture may be laid upon the sandor gravel holding layer 4, upon which a final layer of the same material in considerably less proportion and with a greater proportion of the marble-dust or pulverized oyster-shells, or both, and the cream of tartar and the oxid of zinc, is then laid, securing the desirable exterior finish with sufiicient thickness of the material and at the greatest economy of the ingredients.

It will be obvious that the surface-smooth- I ing ingredients, marble-dust or oyster-shells, or both, throughout the entire mixture unless w en comparatively thin. I do not, however, de-

sire to be limited to any specific manner of application or pro ortion of ingredients.

Generally state the entire composition of which the coating or covering consists is composed of the in edients named. These may be laid on in t e manner stated within the judgment and skill of the o erator, employing different proportions 0 each. For the are not necessarily emplo ed guidance of'those unfamihar with the artof mixing sujchin edients good results may be secured by maiing the entire covering mixture of, say, three parts Keenes cement, one or two parts white sand, according to the stiffness desired, the necessary quantity of water to thoroughly mix .the ingredients and secure plasticity, say, one to two parts, while the 'marble dust, powdered oystershells, oxid of zinc, and cream of tartar may altogether comprise-another part. As stated, these proportions ma be varied from and the cement, sand, an water may be mixed with the marble-dust and oxid of zinc alone.

when it is desired to provide a quick-hardening smooth surface or may be mixed with the case the effect may be-varied'to suit the pur-' pose by mixing the coloring-matter with the facingmixture in proper proportions, while the surface may be decoratedby im ressions Inade in the cement before it is har ened by the use of suitable dies.

'- The facing may be used with good resulth uponthe surface of brick, stone, iron, or steel ing it thereto is similar in use with wooden boxes.

- 'By the application of the facing the ap-' boxes or vaults,'and the operationof appl pearance of the surfaces of the box is sofvious case which will remain permanentlywithout being effected by theelements,'thus.

' 45 effectually preventing access of water,to the tened and beautified, and a feature of great value and advantage is that the covering, which conforms to the shape of the box throughout, forms an independent imperinterior.

Having described my invention, what I claim is 1. The process of coating surfaces consisting -in applying a preliminary coating of itch or tar and asphaltum; then applying a ayer of gravel or sand to said coating while hot; and then applying a finishing coating consisting of Keenes cement, white sand, marble-dust, powdered oyster-shells, oxid of all respects to t e ca ets" zinc, cream of tartar and water' substantially in the manner described. p

2. coating or covering composition consisting of Keenes cement, white sand, marbledust, powdered oyster-shell's, oxid of zinc,

4. A coating'or covering composition consisting of Keenes cement, white sand, marble-dust, cream of tartar and water, sub-' stantially in the proportions set forth.

5. The herein-described covering orcoating consisting of a preliminary lag erof asphaltum andtar or pitch, a secon ary holding layer of gravel or sand embedded therein, and an outer layer composed of cement, sand,

marble-dust, pulverized oyster-shells, cream" of tartar, oxidof-zinc and water, substantially in the proportions set forth.j
