UNITED STATES PATENT OFFICE.
CHARLES Y. WHEELER, OF ALLEGHENY, PENNSYLVANIA.
PROJECTlLE-COA TING.
SPECIFICATION forming part of Letters Patent No. 573,120, dated December 15,1896.
Application filed July 13, 1896. Serial No. 599,041. (1% specimens.)
To all whbm it may concern.-
Be it known that I, CHARLES Y. WVHEELER, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Projectiles; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to projectiles.
My invention consists in a peculiar protecting-coating for projectiles, the object being, primarily, to prevent breaking up of the projectile at the moment of impact and the fusion of the same or pieces of the same to the armor-plate, and incidentally to act as a lubricant for the projectile and to protect the same against rust and corrosion.
It is Well-known to those skilled in the art that an enormous degree of heat is developed at the moment of impact of the shell, accompanied by certain electrical conditions, and that the cracking and breaking of the shell and the fusion of the same with the metal of the armor-plate are liable to occur. discovered that by providing the projectiles witha protecting-coating, composed of plumbago or graphite and silicate of soda, or, as it is commonly tcrmec Water-glass, this liability to fusion is largely, if not altogether, obviated. The water-glass, owing to its peculiar non conducting properties, tends to hinder or retard these electrical conditions and, together with the graphite, which, as is Well known, has the power to withstand enormous degrees of heat, forms a non-conducting film between the surfaces of the projectile and the armor-plate, which precludes that I have;
intimate contact between the surfaces of the plate and shell which is essential to fusion. In the preparation of this coating I prefer to take about equal parts of the graphite and water-glass and mix them together to about the consistency of a creamy paste. I then coat the projectile over at the point or over its entire surface with this paste. This coating may he applied with a brush, by immersion of the shell in the liquid, or in anyother suitable manner. Although I have obtained \Vhat I claim as my invention, and desire to secure by Letters Patent, is,-
A projectile having a protecting-coating composed of plumbago, or graphite, and silicate of soda, substantially as set forth.
In testimony whereof I, the said C. Y. WHEELER, have hereunto set my hand.
CHARLES Y. WHEELER.
