JLEVI s. nos, OF ALMOND, NEW YORK.
Letters Patent No. 94,87 7, dated September 14, 1869.
IMPllIOVED SHEET-METAL FOR ROOFING ANDI'QR OTHER PURPOSES.
The Schedule referred to in these Letters Patent and making part of the same,
after to be set forth also, in the use of lead and hismuth alone for roofin In my patent of J airuary 12, 1869, I stated that the I proportions of the ingredients were as follows:
One-fourth ofa pound of block tin to one pound of llead, or one part block-tin to four parts of lead; also, that Imight'use the metals in equal proportions, part for part, where a finer compound should be required.
I now desire to add bismuth in the following proportions: '1 i To one hundred pounds of block-tin and lead, add from one to sixteen ounces of bismuth, according to the quality of the roofing desired.
When these metals are heated to about from 400 to -600, I ,introduce from a. half to one pound of rosin, which separates all foreign substances from the metals.
In purifying metals in this way, the ingots are free from all flaws, and ,a'more perfect sheet is obtained without flaws or cracks.
The rosin also keeps the metal from chilling, on its passage from the pots or retorts to the ingots or moulds. 1 a
If a cheaper article of roofing is desired, the block 1 tin can be entirely dispensed with, and a roofing composed solely of lead and bismuth be formed that will answer all ordinary purposes. Having thus fully described my invention,
lVhat I claim as new, and desire to secure by Letters Patent, is- V 1. As an article of manufacture, a metallic roofing, composed of block-tin, lead, and bismuth, or lead and bismuth alone, substantially as herein set forth.
2. The process above described, for manufacturing metallic roofing, substantially as herein set forth.
In testimony that I claim the foregoing, I have hereunto set my band, this 24th day of May, 1869.
