J. MATHER. Annealing Metal.

JAMES MATHER, OF HARWINTON, CONNECTICUT.
ANNEALING METAL.
SPECIFICATION forming part of Letters Patent No. 234,193, dated November 9, 1880. Application filed September 1, 1880. (No model.)
To all whom it may concern:
Be it known that I, JAMES MATHER, a citizen of the United States, residing at Harwinton, in the county of Litchfield and State o't' Connecticut, have invented certain new and useful Improvements in Breaking the Temper or Annealing Metals and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.
The present invention has relation to new and valuable improvements in the method of drawing down or reducing the temper of metals during the working of them.
It is well known that metal, while being rolled into sheets or drawn into wire, hardens by the friction employed in working it, and that it often requires to be annealed or softened, which is done by heat.
I have found by experiment that this annealing or softening of metals can be successfully accomplished without resorting to the action of heat by what may be termed crinkling, or running the metal in flexures between a series of rolls.
These rolls are represented in the drawing by the letter A, and may be of any suitable number and size, with their peripheries either smooth or corrugated in any desired manner to suit the article operated upon, as found desirable. The larger rolls B C are those usually employed for rolling sheet metal, the rolls A being arranged in front of them. These rolls A are looselyjournaled in a suitable frame or other fixture.
The metal represented at a, after passing between the large rolls B C, passes under one of the small rolls Aand over the roll next following, the rolls being arranged with relation to their distance apart, as found most convenient, according to the metal to be operated upon and the amount of crinkling desired to be imparted thereto, such metals as brass or copper usually requiring less manipulation than iron or steel. By thus passing the metal between the rolls A it draws down or reduces the temper, thus serving the same purpose as annealing, with much less labor or expense accompanying the process.
Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
The method of working metal, which consistsin subjecting it to a pressure, as described, and then to successive flexures in reversed direction, as and for the purpose set forth.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
JAMES MATHER.
