WILLIAM DOGKER, OF NEW ORLEANS, LOUISIANA.

MODE 0F ROOFING HOUSES.

Speccation of Letters Patent No. 1,887, dated December 10, 1840.

T0 all /LULOW may concern Be it known that I, WILLIAM Dooinn, now of New Orleans, State of Louisiana, have `invented a new and improved mode of roofing in slate, tile, or metal, which improvement may be applied to perpendicular surfaces, and to facing the exterior walls of buildings of brick, plaster, or wood, rendering them water-tight; and I do hereby declare that the following is a full and e-Xact description.

This improvement consists in using instead of the double courses of slate (which is the present mode of rooting) I use a single coursing', together with certain metallic plates and hydraulic cement vthe whole combined and prepared so as to make the root light, tight and durable. The metallic plates above mentioned I call intermediates and they be made ot' sheet iron, tin, Zinc, lead or other metal, four inches or more in breadth according to circumstances and equal in length to the length ot' the joint of the slates, tiles, or metal sheets used in the rooting. These plates are prepared and coated with paint, or lacquer, or Japan varnish or oil so as to resist the action of the atmosphere or water. These plates are laid so that the joints of a row of slates or tiles or other material used in rooting shall meet over the center of the plate. The edge ol each slate or tile or metal sheet should be bedded in hydraulic cement or composition calculated to resist the wet, and produce a drain, andV prevent the slate or tile from coming in contact with the said intermediate, all of which will be more readily understood by reference to the drawing.

a, o, a, is a row of slates or tiles or metal sheets say about twenty inches lo-ng and ten broad. b Zv-Z) b-Z) I) Z are the joints or line of meeting between them; c, c, C, represent the metallic plates or intermediates about ten inches long by about four or six broad, bedded in hydraulic cement.

The rooting sheets lap four inches vover edges in the usual manner. The plates or intermediates and the slates or tiles or metal sheets are tacked or nailed to the roof or top by nails under the lap as shown in the drawing. y

Vhat I claim as my invention and desire to secure by Letters Patent is- Laying the slates, tiles, sheets of metal7 &c., constituting the roofing in hydraulic cement or other waterproof composition, in combination with the intermediate plat-es, which plates should be covered with paint, varnish, lacquers, &c., in the manner and for the purpose described. j
