Description
UNITED STATES PATENT OFFICE.
SAMUEL SINGLEY, OF ST. LOUIS, MISSOURI, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE MAGNOLIA ANTI-FRICTION METAL COMPANY, OF NEW YORK, N. Y.
SPEGIFIGATIQALforming part of Letters Patent No. 429,249, dated June 3, 1890.
Application filed July 21, 1887. Serial No. 24 1.869. (Specimens) To all whom it may concern:
Be it known that I, SAMUEL SINGLEY, of St. Louis, in the State of Missouri, have invented a new and Improved Anti-Friction Alloy, to be used in the manufacture of bearings, steps, &c., the object of the invention being to produce an anti-friction alloy which will withstand the strain to which it would necessarily be subjected when used as a bear- 1o ing or step.
My composition is made by the use of the following substances in proportions between the following limits, substantially as stated, viz: Lead, two hundred to four hundred parts;
I 5 antimony, forty to eighty parts; tin, fifteen to thirty parts bismuth, five-eighths to one and one-fourth part. These proportions will vary between the limits stated, depending upon the quality of the lead. Hard lead will require less of the other ingredients than will soft lead. Ordinarily the proportions about midway between the extremes mentioned will be found most satisfactory. These proportions, expressed in the nearest whole num- 2 5 bers, are about: Lead, three hundred and twenty parts; antimony, sixty-four parts; tin, twenty-four parts; bismuth, one part. The tin I prefer to use in the form in which lead solder is generally cast, tin so cast being 10- 0 cally termed by some tin-lead or tin-leads.
In preparing and cleaning the lead I prefer to use sal-ammoniac, employing from fiveeighths to one and one-fourth part, by weight, as compared with the lead, the sal-ammoniac being added to the lead when molten, and the molten mass stirred and the scum and dross removed from time to time. I also prefer to use from seven and one-half to fifteen parts, by weight, of graphite in a powdered condition; and I have found such use of sal-ammoniae and graphite of great benefit in improving and affecting the quality of the resulting composition.
The metallic ingredients are melted and added one byone, as named, care being taken to avoid overheating or excessive oxidation.
hat I claim as my invention, and wish to secure by Letters Patent, is-
1. The composition of matter for anti-friction purposes, consisting of lead, from two hundred to four hundred parts; antimony, forty to eighty parts; tin, fifteen to thirty parts, and bismuth, five-eighths to one and -one-f0urth part, substantially as described.
2. The composition of matter for anti-friction purposes, consisting of lead, three hundred and twenty parts; antimony, sixty-four parts; tin, twenty-four parts, and bismuth one part, substantially as described.
SAMUEL SINGLEY.
