UNITED STATES PATENT onnron.
ENRIQUE A. TOUCEDA, F ALBANY, NEW YORK.
ANTIFRIGTION-ALLOY.
Specification of Letters Patent. Paten'ged Sept 21, 1909,
Application filed January 6, 1909. Serial No. 470,932.
No Drawing.-
To all whom it may concern:
Be it known that I, ENRIQUE A. ToUoEnA, a citizen of the United States, residing at Albany, county of Albany and State of New York, have invented certain new and useful Improvements in Antifriction Alloys, of which the following is a specification.
This invention relates to the class of alpotassium cyanid, which acts as a flux and which also serves to protect the molten metal from oxidizing agencies. After the cadmium has reached a temperature of about 150 degrees Fahrenheit above its melting point, the magnesium is, by means of a pair of tongs'or other suitable apparatus, thrust quickly down through the flux, and held immersed in the molten cadmium until the magnesium is also melted, after which the molten mass of metal is run off .into suitable molds in the usual manner.
I do not wish to be limited to the foregoing method of producing my improved alloy, as other methods may be employed without 'depa-rtingfrom the spirit of my invention.
An alloy produced in accordance with my invention has a very fine grain, and is readily adaptable,by changing the relative proportions of cadmium and magnesium, to the various conditions of load, shock and speed of rotation to be met by hearing metals under diflierent conditions of use. I have found this alloy containing from one-half of one per cent. to two and one-half per cent. of magnesium to be very useful under ordinary conditions, such an alloy being both hard and tough,and well adapted to sustain heavy loads, while ossessing antifriction qualities of a high egree.
Magnesium in proportions less than three and one-half per cent. imparts great hardness to cadmium without destroying or materially reducing the malleabilityor ductility of the cadmium. Less than one-half of one per cent. of magnesium can be advantageously used whcre the load is very heavy, the rotary speed high, and the hearing not subjected to severe shocks. When the load is constant and light, and the speed high, the proportion of magnesium may be increased to five per cent., or even more, the resultant alloy being more brittle and extremely hard.
I do not wish to be limited to a bearing composed of an alloy containing only cadmium and magnesium, as I consider within the scope of my invention any bearing com posed of an alloy wherein a cadmium constituent is hardened by a magnesium constituent.
What I claim as new and desire to secure by Letters Patent is 1. An antifriction bearing composed of an alloy containing cadmium and magnesium.
2. An antifriction bearing composed of an alloy containing a relatively large proportion of cadmium and a relatively small proportion of magnesium.
3. An antifriction bearing composed of an alloy containing cadmium toughened and hardened by the presence of magnesium.
4. An antifriction bearing composed of an alloy'containing substantially three and one half per cent. of magnesium and a relatively large proportion of cadmium.
5. An alloy containing a relatively large proportion of cadmium and a relatively small proportion of magnesium.
6. An alloy containing substantially three and one-half per cent. of magnesium and a relatively large proportion of cadmium.
In testimony whereof, I have hereunto set my hand this 28th day of Dec. 1908.
ENRIQUE A. TOUCEDA.
