PROCESS FOR WORKING METALS.
1L,4l27,llli. Specification of Letters Patent.
Application filed June 28, 1919. Serial No. 307,466.
Patented Aug. 29, was.
Be it known that I, OLIVER C. GILBERT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes for Vorking Metals, of which the following is a full. clear,'concise, and exact description.
This invention relates to an improved process for working metals of strip or strand form to fabricate the same into a flattened ribbon suitable for use as tinsel and the like.
Heretofore, tinsel has been made by passing wire. between a pair of pressure rolls which flatten it. Attempts have been made to subject the wire to a plurality of flattening agencies during one passage by feeding the wire through two or more pairs of pressure rolls spaced apart. In practice, however, it has been impossible to subject the wire between the rolls of each pair of rolls to the same flattening pressure or to cause the friction onthe wire between each pair of rolls to be the same. As ta consequence, the second pair of rolls frequently subjects a greater pull and tension on the wire than the first pair of rolls can relieve, causing the wire between the two pairs of rolls to break.
The improved process herein consists in passing the wire around a roll which is sub jected to pressure at two diametrically opposite points on its periphery by two other pressure rolls. driven and the two oppositely positioned pressure rolls operate as idlers. Due to this arrangement the wire during one passage is subjected to two flattening agencies, but since only one driving element is employed, no tension or strain is exerted on the section of wire between the two points where pres- The middle roll alone is,
sure isapplied to it and therefore no breaking'of the wire is encountered.
The drawings illustrate diagrammatically one conventional means for performing the process in which the wire is mounted upon a storage roll 1 from which it is fed around a central roll 2 and between two pressure rolls 3 and 4, arranged diametrically opposite each other with their shafts in the same vertical plane with-the shaft of the roll 2. A. pulley 5 is secured to the shaft supporting the roll 2 and is driven'by a belt 6 actuated by any suitable source of power. Springs 7 or other suitable means are employed to ex ert pressure between the idler rolls 3 and 4: and the driven roll 2.
What is claimed is:
1. That process of working metals of strip or strand form which consists in passing the metal around a drum so that a length thereof is kept in constant engagement with the arced path on the surface of the drum which subtends an angle of approximately 180 at the axis of the drum and subjecting it to pressure at two circumferentially spaced points while it is thus hugging the surfaceof the drum.
2. That process of working tinsel which consists in drawing the material over a drum so as to keep it in a taut and slightly stretched condition while it is in engagement with a path on the surface of the drum, said path consisting of a series of successive circumferential points, and subjecting it, while in such a taut and slightly stretched condition, to the pressure of two idling rollers oooperating with the said drum at two circumferentially spaced points.
In witness whereof, I hereunto subscribe my name this 19th da of J une, A. D., 1919.
