Description
ITED STATES PATENT oEEIoE.
EDWARD D. GLEASON, OF NEW YORK, N. Y., ASSIGNOR TO PLASTIC METAL COMPANY,
OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
PROCESS OF MAKING LEAD-COPPER COMPOSITIONS.
Specification of Letters Patent.
1% Drawing. Original application filed March 7, 1913, Serial No; 752,601. Divided and this application filed.
March 31, 1913. Serial No. 757,860.
To all whom it may concern Be it known that I, EDWARD D. GLEAsoN, a citizen of the United States, residing in Brooklyn, in the county of Kings, city and State of New York, have invented a certain new and useful Improvement in Processes of Making Lead- Copper Compositions, whereof the following is a specification.
This application is a division of my application Serial #752,601, filed March 7, 1913 for Letters Patent of the United States for compositions are but mechanical mixturesv wherein copper is held in a finely divided state in a matrix of lead.
Another object of my invention is to provide such compositions including a given percentage of copper but of different degrees of hardness.
The effect of my improvement is to provide a composition which is homogeneous in that the copper therein is comminuted to the greatest possible extent and equally distributed throughout the mass of the composition. I have discovered that the eflect aforesaid is attained by adding to the molten copper, in the process of making such compositions, a non-metallic derivative of the other metal, capable of increasing the miscibility of copper with that metal, to wit, lead sulfid, and particularly the native lead sulfid, galena. For instance, I fuse pounds of copper and add thereto 5 pounds of galena and then gradually add, to said mixture, 45 pounds of lead. The fused mixture is then poured into pig, ingot or other suitable molds, and, when congealed, fracture thereof shows that the cast metal is homogeneous.
Harder alloys may be formed by taking 50 pounds of copper, 10 pounds of galena and 40 pounds of lead or 45 pounds of copper, 10 pounds of galena and 45 pounds of lead; said ingredients being mixed as in the first instance above described.
As above indicated, the use of galena is effective for the purpose described when used in alloys containing tin. For instance, I take parts copper, 30 parts lead, 5 parts galena and 5 parts tin, or, 55 parts copper, 35'parts lead, 5 parts galena and 5 parts tin. However, such alloys including tin form the subject matter of my application Serial #752,600, filed March 7, 1913 for Letters Patent of the United States.
I do not desire to limit myself to the precise methods of procedure or proportions herein set forth as it is obvious that various modifications may be made therein without departing from my invention as definedin the appended claims.
I claim 1. A process of making a composition containing copper and lead which consists infusing said metals with lead sulfid and thereby increasing the miscibility of said metals.
2. A process of making a composition which consists in fusing lead sulfid with copper and then adding lead thereto and fusing the mixture.
3. A process of making a composition Which consists in fusing with copper a nonmetallic derivative of another metal, capable of increasing the miscibility of copper with that metal, and then. adding the other metal thereto and fusing the mixture.
4. The process of making a composition containing copper and another metal which consists in fusing with the copper a sulfid of the other metal, and then mixing the other metal therewith.
5. A process of making a composition containing copper and another metal which signed my name at Brooklyn, New York, consists in fusing therewith a non-metallic this twenty-eighth day of March, 1913. derivative of the other metal, capable of EDWARD D. GLEASON. increasing the miscibility of copper with Witnesses:
5 that metal. BENJAMIN ZEKOWSKI,
In testimony whereof, I have hereunto SIEGMUND ZEKowsKI.
