IMPROVEMENT ,IN METALLIC COMPOSITIONS FOR BEARINGS 0F MaCHiNEliY, &c.
' Specification forming part of Letters Patent No. 3.896, data-dfllminary ill, 143.
To all whom it mug concern:
13c it .known that we, Ixcm-zasn HILL, of Boston, in the county of Suii'olk and State of Massachusetts, and ,losiarir DIXON, of
Taunton, in vthe county of Bristol and Stateal'oresaid, h re discovered a new and useful Metallic Composition for the Hearing and fearing Surfaces of Machinery, or a new and useful method of preparing zinc so that it may be used for such bearings and surfaces; and wedo hereby declare that the following is a full and exact specification ofithe s'everal ingredients and their n'oportions, and of the manner of admixing or compouifdin g the same, as well as the claim for which we solicit Letters Patent.
Our composition consists mostly of zinc (which, as is well known, belongs to the classof cheaper metals) hardened by being compounded with what we denominate a f hardening composition. fl'his latter composition is formed ofthe following metals mixed in a state of fusion in the proportions hereinafter specitied viz., fifteen parts of tin to thirty-two parts of copper.
This composition, in a state of fusion, is to.
be admixed with molten zincand tin (although tin is not absolutely essential) in the proportion of two parts of the said hardening composition to nineteen parts of zinc and'froin three to five parts of tin, according 'to the peculiar purpose for which the com position is to be used, the tin specified as to be added last having the tendency to render the compound, when cold, more or less ductile, according to the quantity of thesame incorporated therewith. The metal formed without the addition of the last-named proportion of tin, hen brolgen, will have the appearance of cast-steel of a coarse quality but the addition ofthe tin will'make it stronger and cause it to be liner in grain, until four parts of the same be added, whcn thc appearance of the metal, on its being broken, will he like that of line cast-steel, and more closely re sembling the same than any other metal.
The great strength of the composition, combined with a certain degree of softness which it-possesses, renders it highly useful in the construction of bearings for rubbing surfaces of machinery, as it is capable of resisting for a,
great length of time the effects of wear and at trition. The large proportion of zinc used in forming the compound renders'its use in the mechanic arts much less expensive than' the metals ordinarily employed for these purposes, the cost being much less than any other composition where copper and tin are the princi pal metals used.
What we claim as our discovery, and desire I
