'NITED STATES PATENT OFFICE.
GOLDSBOROUGH ROBINSON, OF LOUISVILLE, KENTUCKY.
IMPROVEMENTIN RooFs.
Specification forming part 01" Letters Patent No. 149,791, dated Al'l'il 14. 1874; application filed August 5, 1873.
To all whom it may concern:
Beit known that I, GOLDSBOROUGH ROBIN- SON, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and Improved Roofing Process and I do hereby declare the following to be a full, clear, and exact description of the same.
The invention relates to a mode of forming a weather-proof roofing on the sheathingboards or other covering of a building.
It will first be described in connection with all that is necessary to a full understanding thereof, and then clearly pointed out'in the claim.
I mix water-lime or hydraulic cement with sand and Water, or equivalent materials, or with water alone, until it is brought into a pliable and plastic state, and then apply the same upon the sheathing-boards or other covering of the structure, until a substantial layer is produced.
This makes a continuous roof, which has no joints unless desired, is non-elastic, andis incapable of cracking by contraction and expansion.
efficient, and that it gives promise of great durability. l
One or more layers or coats may be applied to produce a roof of greater or less thickness.
1 am aware that hydraulic cement has been heretofore used in one or more layers between the sheathing and roof of a house as a waterrepellent, or as a foundation for other outside covering, and this I do not claim.
An experiment has demonstrated vthat it is not only practicable, but particularly
