This invention relates'to White metal alloys for use with bearings in all cases Where there is hard and abrasive wear with heavy load 'and in particular with the side metalsot engine axle boxes, brasses,and some tormsof oross-heads.
My improved alloys contain lead in greater quantity than that of any one of the other constituents; antimony and tin in varied but out in substantially equal amounts, and the copper being present in an amount substantially equal to one-half the amount of the antimony.
Intestimony whereof I have ailixed my signature.

approximately equal proportions to each other; and copper in an amount approximating to one half of the quantity of antimony.
A percentage composition of one form 0 alloy is :-Antimony and tin about 12.5 each; copper from 6 to 7; the remainder being lead. For normal Wear with this particular alloy the amount of copper should be close to 6 per centum, While for a hard alloy the copper should range centages being by weight.
The copper may be Wholly or in part replaced by nickel, and various alloys are formed by altering slightly the amounts of antimony'and of tin While retaining approximately equal proportions of each.
In the preparation of my alloysl prefer to melt the desired quantity of copper an 'add the antimony and'some of the tin to the molten mass. The remainder of the tin and 'the'whole of the lead are then added, reasonable steps being taken to prevent undue oxidation.
I claim- 1. An alloy consisting of lead, antimony,
tin, and copper in which the antimony rep-' resents about 12 per centum by weight, the tin about 12 per centum, the'coppcr from 6 to 7 per centum, and the lead constitutes the remainder.
2. An-alloy consisting of lead, antimony, tin and copper, in which the antimony represents from to per cent by Weight, the tin from-10 to 15 per cent, the copper from 5 to 7.5 per cent, and the lead constitutes the remainder, the antimony and tin being presabout 7 per centum, the per
