No Drawing. ,Original application filed October it. 1912, Serial No. 723.579.
Specification of Letters Patent.
Divided and this application filed November 16, 1912. Serial No. 731,864.
To all whom, i! may concern:
Be. it. known that; I, Enwann I). (,tiacasox, ot Brooklyn, in the county of Kings, city and State. of New York, hai'e invented a certain new and useful improvement in Lead topper-(Fin Alloys, whereof the tollowing: is a speeititaition. 1
This applieation is a division of my application Serial 793,579 filed )etoher 3. till) for l retters latent ot the United States.
My invention relates to plastic alloys including lead. copper and tin, which may he advantageoualy used in the mamitaetiu'e of hearings for shafts, eto.
it is an olijeet of my invention to proride sueh alloys, free. from lead sweats and segregation, hit-h are deteeta'nsually tound in such alloya due to lat-k otatliuity ot the lead' tor the oopper or eopper and tin, and the high speeitie gravity and low melting point at lead. For. at heat. sueh alloys are but meohanieal 1ni.\'ture wherein copper is held in a finely divided state in a. matrix ot lead.
Another ohjeet. of my inventirm lH to provide SIIt'll alloys int-hiding a given pereentage of u'ipper but of ditl'erent degrees ot hardness.
'lhe etl'eeti ol. my improvement. is to pro vide an alloy whie'n is homogeneous in that the eopper therein is eomniinuted to the greatest poaail le extent and equally distributed throughout the mass of the alloy.
111 praetisingr my invention, l incorporate horon in copper. as graphite exists in east iron; sueh a horon eopper product and a method of produein; it hein;- the suhjeet matter of another applieation Serial 7:51.8(33 tiled Noremher lti. 1912 For Letters Patent of the linited States. Such horon eopper is harder than (u-dinary copper and by its employment in varying pereentages I am ahle to make e.o ')perlead tin alloys whieh are alike in total m-reentage ot copper hut dittiterent in dqi'rees ot hardness. For instant-e, an alloy in lltft'ultltll'lt'tt with niy invention may eontain fit) parts of horon eopper and would he mueh harde. and more lirlltle than.
anotlie' alloy in aeeordanee with my in\'ention, eontaii'iing :30 parts of copper if the latter ia an aggregate of ordinary eopper and boron eopper. In other words. diminiahine' the percentage of boron in the alloy diminishes the hardness and hrittleneas thereof. and variation in this reapeet eonreniently etleeted hy employing more or ltta'rj ot' the horon mpper. to wit. the eop per eontaining horon, with more or less; oopper devoid of horon. in any ease I prefer to proeeed hy tirst melting: the (topper. with suitahle applianres, and adding the lead and tin thereto when the eopper is in the tluid state. and. then stirring or" otherwise agitating the mixture liet'ore pouring it into ingot; molds. -\ll oti these products are tree from lead sweats or aegregation and have an unetuous antifrietional texture. and a aurfare reaemhling planiahed t-opper; properties whieh are advantageous in hearings. piaton rings, gaskets and steam parking.
In making alloys of eopper, lead and tin; the tin will segregate it not in the proper proportion tor the eoppei ani l lead. For instant-e. it' eo'pper t'fi' parts, lead LE-l pal-ta and tin 9 parts are mixed in aeeordanee with ordinary foundry praetiee, the lead will sweat out and form in little pool and the tin will segregate and stratify. ()n the eontrary, hy the employment of horon copper as ahore eontemplated sueh alloys of eopper. lead and tin may he made entirely homogeneous and of any desired degree of hardness.
I do not desire to limit myself to the pre rise methods of proeedure or proportions herein set forth as it is ohvious that various moditieations may he made therein without departing from my invention as defined in theappended claim.
An alloy inelnding lead, copper, horon and tin.
In testimony whereof, 'l have hereunto signed my name at Brooklyn, New York, this 13th day of Nov 1912.
