HAR ENmeoF CAST-IRON AND THE LIKE.
No. 878,053. x
' To cli it may concern:
Be it known that GE'oRGE' HENRY HAw-.
' KINS EM TT,- late a subject of the King of.
' dening theresulting metal, the degree of hardness being dependent upon the,pr0 tionsadopted. 1 Y
castings for rock 'crushers, stamp mills,
sheavesforwire ropes, and the like-articles, where a hard-metal is required; the resulting metal can be made so hard and tough that it will withstand the action upon it ofthe hardest steel, and it can be made of uniform hardness throughout, or, if required, only the I desired part ofthe casting may be hardened,
the rest being left comparatively soft.'
According to this invention" a compound prepared according to the following formula sulfur '8 pounds,dryred,lead 1 pound, lamp 15 made, and. it is added to and Well mixed with the molten metal in the different r0- portions hereinafter given to suit the di erent requirements. a
The compound consists of:' Flowers of black 4 ounces. These. ingredients are ground in a mill, then run through asieve, and Well mixed together.
Specification of Iietters Patent. Aiiplication filedfebruary 17. 1906- Serial No. 301.679.
The invention is particularly applicable to I The following ives'the proportion of comound and metfi for typical cases, and may e taken as a guide inselecting the propertions for any given purpose :For general purposes, 1 lb. of the compound is added to 30 lbs. of molten" iron; for rock crusher castings (chilled), 1 lb. of coin oundto 40 lbs. of iron; for sheaves (not. pound to 25 lbs. of Iron; and for sheaves with soft core, 1 lb. of compound to. 30 lbs. of iron.
The proportions given both for -the com position of. the compound, and-for the pro- Patented Feb. 4, 1908.
ed) 1 lb. of comportions of the latter to-the iron, for the dif- I ferent purposes, are of. course approximate; these may be varied and equivalent substances substituted for those mentioned within the limits of the invention.
I claim as the invention of GEORGE HENRY HAWKINS EMETT the following: t
L The hereindescribed compound for hardening iron, consistin of'fi'o'wers ofsulfur, red'lead and lam blaci a 2. The herein escribed compound for hardenin'g iron consisting of flowers of sulfur, dry red lead and lamp. black in "substantially the proportions of 8 pounds of sulf'ur,1 pound of lead and 4 ouncesof lamp black.
In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses. H
