Specification of Letters Patent.

Patented May 15, 1917.

To all whom it may concern:

Be it known that I, JOHN S. MCGEHEE, a citizen of the United States, residing at Palmersville, in the county of VVeakley and State of Tennessee, have invented a new and useful Roofing, of which the following is a specification.

This invention has reference to roofing, and its object is to provide a substitute for shingles and other rooting which may be applied with a trowel and which, moreover, is fire and waterproof.

The roofing while intended particularly for a roof covering, may be applied to side walls, or wherever al covering to which the rooting is adapted may be employed. However, for the sake of simplicity of description the invention will be referred to as a roofing without thereby limiting the uses of the invention to such particular purpose.

In accordance with the present invention a suitable foundation of laths or strips is provided upon supporting timbers, and such strips are covered by a ne mesh wire screen which in turn is covered by a coarse mesh wire screen, and to the wire screening there is applied a composition of materials mixed in suitable proportions, and in a condition permitting the application by means of a trowel or other suitable tool. The composition dries hard and firm, hardening slowly with freedom from cracking, and when completed is'both weather and ireproof with a smooth, substantially glazed surface.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawing forming part of this specication, with the further understanding that while the drawings show a practical form of the invention, the latter is not conlined to any strict conformity with the showing of the drawings, but may be changed and modied as long as the changes and modifications come within the scope of the appended claims.

In the drawing, the figure is a perspective view to a certain extent schematically representing a small section of a roof provided with the roofing of the present invention.

In carrying out the invention, the supports to which the roofing is to be applied, which supports are not shown in the draw ing, are covered with strips or laths 1 suitably spaced apart, say, about half an inch, so that there is no buckling of the laths should the latter swell from any cause. Covering the laths is a layer 2 of ne mesh wire screen held to the laths by staples 3 or otherwise, and covering the screen 2 is a layer of wire screen 4 which may be of about half inch mesh, althou h any particular mesh is not obligatory. he screen covering 4 is held in place by staples 5 or in any other suitable way. The purpose of the screen covering 4 is to provide key seats for anchoring a layer 6, of a composition to be described, to the basic portion of the roof covering, while the fine mesh wire screen 2 prevents passage of the composition to the spaces between the laths, and so far as any of the composition 6 which may reach the wire screen 2 is concerned, the latter will act as an anchoring means therefor.

The composition covering 6 is applied in a layer of, say, half an inch in thickness, and in strips of, say, about two feet wide extending from the eaves to the ridge or comb of the roof, .each strip being separated from its neighbor by a space of, say, half an inch, and such a space being indicated at 7 in the drawing.

The composition G is made up of sand, ce-y mfeliPt, red oxid of iron, yellow ocherplastme'i1` o arismfz'alum, granulatedsl'gr dilurmtli enoi'i'g'h water to prm a work`lile plaster capable of being applied to the basic portion of the roofing with a trowel or other suitable tool.

As an example of the composition, a certain quantity is made up of one hundred pounds of good clean sand, one hundred pounds of good cemen."o'1i` and one-quarter pounds of red 0x15 of iron one-quarter pound of ello-w o-cer. one pound of builders laster o aris. one ounce of salt eter onea e o a um one poun ulated su ar and'mound of sulfur? Twcement, red oxid omher,

x nd ster of Paris are thoroughly mixed y The saltpeter, alum, sugar and sulfur in the quantities 'ven above are dissolved in one gallon of oiling water and when cool the solution is strainmhen mixed with the first-named ingredients with suicient additional water to make a trowel mortar.

The roofing composition is applied in Kmme 106. COMPOSITIONS,

strips as stated, with spaces 7 between the strips until the Whole roof or space to be covered is finished, and then the various strips are kept damp until thoroughly set, this being accomplished by covering the Whole roof with sacking and keeping the sacking wet. Then the narrow spaces 7 are filled in with the saine composition packed in with a trowel and allowed to set. Finally a suitable quantity of cement is mixed with enough of the solution made up of saltpeter, alum, sugar, sulfur and water to produce a thin paste, thin enough to be applied to the applied rooting composition with a brush, and this is then smoothed down with a trowel to fill all erevices and holes and to produce a finishing glaze adding to the appeaiance of the roof. The filling for the space 7 is indicated at 8, and the final brushed-on coating is indicated at 9, the filling 8 being slightly pointed if desired to produce a suitable ei'ect upon the roof.

The plaster of Paris added to the cement and sand makes the composition firmer than when the plaster of Paris is omitted. The red oxid of iron and the yellow ocher serve as coloring matters. The saltpeter is used to keep the composition from hardening too fast and cracking, and also serves as an atmosphere feeder to cause the crystallization of the ingredients. The sulfur and other of the ingredients contribute to the gloss, and all the ingredients act to produce a firm and durable rooting free from liability of crack and thoroughly resistant to Weather condi tions.

It will be understood, of course, that the coloring matters Will be varied in accordance with the color it is desired the rooting should have.

The composition may be made up into shingles, but it is advantageous to apply it as described, for the gutters and valleys may be formed of the composition in one piece with and at the same time the roof is produced.

What is claimed is l. A rooting composition comprising sand, cement, plaster of Paris, saltpeter, alum, sugar and sulfur.

2. A roofing composition, comprising sand, cement, plaster of Paris, saltpeter, alum, sugar and sulfur in substantially the parts of one hundred pounds of sand, one

undred pounds of cement, one pound each of plaster of Paris, sugar and sulfur, one ounce of saltpeter, one-half ounce of alum, coloring matter and Water. o

3. A roofing compound consisting of sand, cement, plaster of Paris, red oxid of iron, and yellow ocher mixed dry in substantially the proportions described, a solution of salt: peter, alum, sugar and sulfur substantially in the proportions described, and Water in sufiicient quantity to make the composition of the consistency of trowel mortar.

4. A compound comprising cement, saltpeter, alum, sugar, sulfur and Water, in substantially the proportions described.

In testimony that I claim the foregoing as my own I have hereto atlixed my signature in the presence of two Witnesses.
