Description

' begins covered crucible ears HENRY K. SANDELL, OF CHICAGO, ILLINOIS, ASSIGNOR T0 HERBERT S. MILLS, U15
- CHICAGO, ILLINOIS.
WHITE METAL ALLOY eashes.
No Drawing.
To all whom it may concern:
Be it known that I, HENRY K. SANDELL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in White Metal Alloys, of which the following is a specification My invention relates to certain improvements in white metal alloys and will be fully understood from the following specification.
For the preparation of my new alloy the following procedure is adopted:
10 parts by Weight of bismuth together with 10 parts by weight of tin is melted in any suitable apparatus, preferably in a crucible which may be covered to exclude the atmosphere, the molten mass is permitted to cool very slowly until it reaches a temperature just above its setting temperature. t the moment before solidification or setting there is added 10% of mercury, under which conditions the mercury may be caused to dissolve itself in the mixture. This primary alloy is then permitted to set.
20 parts by weight of zinc are now melted in a suitable crucible as, for example, the above referred to, and the zinc is permitted to cool to a point just above its solidification temperature, primary alloy of. bismuth, tin and mercury is now added to the zinc and this mixture is permitted to, set. llhe secondary alloy is now com' lete. I
The third step of the process consists in Specification of Letters Patent.
' produce Patented libero Application filed l'une 18, 1917. Serial No. 175,3?1.
melting in the covered crucible 50 parts'by weight of copper, the temperature of the molten copper is slowly reduced and just before solidification begins, the secondary alloy prepared as above is added to the copper.
My alloy of mercury, bismuth, tin, zinc and copper is now complete and may be cast and otherwise fabricated as desired,
My improved alloy is a white metal which takes a brilliant polish and holds it on ezr posure to the atmosphere. its melting point is slightly below that of copper, its tensile strength is relatively low and it relativel brittle, giving a fracture similar to that of glass.
What I claim is:
'1. An alloy comprising 10 parts by weight of mercury, 10 parts by weight of bismuth, 10 parts by weight of tin, E20 parts by weight of zinc, and 50 parts by weight of coppen 2. The method of preparing the abovedescribed alloy which comprises forming the primary alloy of bismuth and tin, add ing to such primary alloy while, the same is Eiil till
at a temperature not substantially exceed substantially exceeding its melting the final alloy.
