Description

UNITED: STATES PATENT ()FFIoE.
WILLIAM I. ARNOLD, OF NEW YORK, N. Y.
IMPROVEMENT IN THE MANUFACTURE OF ROOFING AND SHEATHING FELT.
able for lining or sheathing frame-houses to keep out heat, wind, and cold, and also for putting under slate and tin roofs, and as a substitute for lath and plaster I use the fol-.
lowing new composition of matter: First, I take the reed-cane disintegrated as aforesaid, and reduce it to pulp in the ordinary way, but as it is too soft and tender when used alone, I mix with it some hard stock or straw-pulp sufficient to give the productthe necessary compactness and tenacity, preferring, for that purpose, to use two-thirds caneiiber to one-third straw. After the cane fiber and the straw pulp are thoroughly,mixed together in the paper-makers rageugine I applyprosin-size and alum to the pulp in the rag-engine to render the product sufficiently water-proof for the purposes to which it is to be applied. The size is beaten up with the pulp, which is then run off upon a paper-machine.
This new article of manufacture is well adapted to and cheap enough for building purposes aforesaid. It is stout, strong, pliable, sufficiently non-absorbent of moisture and repellent of water, and not liable to warp.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is
1. The combination of reedecane, disintegrated by the explosive force of steam, and straw-pulp or hard stock treated with rosinsize and alum in the rag-engine, for the production of paper sheathing-felt, as set forth.
2. As a new article of manufacture, the pa per sheathing-felt above described.
Chicago, 22d September, 1871.
