PHILIP GAREY, OF CINCINNATI, OHIO.
PULP-BOARD FOR ROOFING PURPOSES.
SPECIFICATION forming part of Letters Patent No. 300,946, dated June 24, 1884.
' Application filed February 4. 188-1. (Specimens) To all whom it may concern:
Be it known that I, PHILIP CAREY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Pulp-Board for Roofing Purposes, of which the following specification is a full, clear, and exact description.
My invention has for its object the production of pulp-board chiefly designed for roofing purposes, and has for its object the improvement of this class of boards by rendering the same more durablejand less liable to be broken by anypressure that-might be brought to bear on them, and at the same time making them practically fire-proof.
To this end the novelty of my invention consists in a pulp-board composed of wood pulp, asbestus fiber, or any other mineral fiber, any suitable clay mixed together while in a pulp, then pressed or rolled into sheets or boards, dried, and afterward coated or saturated with asbestus, asphaltum, or any other fire or water proof paint, as will be herewith set forth and specifically claimed.
I am aware that boards for roofing have been before made of wood pulp and other substances; but the objection'to such boards is that they are very brittle and become easily split or broken.
I am also aware that boards of wood pulp and other substances have been,while in a pulp state, saturated with oil before being dried; but such boards were also brittle and lacked the element of being fireproof.
I prefer to construct my boards of a pulp made up of wood fiber, asb estus fiber, or any other mineral fiber, and suitable clay, in the proportion of sixth-tenths, three-tenths, and
one-tenth, respectively, which pulp is thor- 40 not readily split or break, and at the same time will be practically fire-proof.
I do not limit myself to the proportion of ingredients named, as they may be varied; but I have stated the proportion I consider best, and,
Having thus fully described my invention, I claim As a new article of manufacture, a pulpboard composed of wood'pulp, asbestus, or any other mineral fiber, and any suitable clay, mixed together while in a pulp state, then pressed or rolled into a sheet or board and dried, and afterward coated or saturated with asbestos, asphaltum, or any other fire or water proof paint, substantially as described.
PHILIP CAREY.
