I c. R. NELSON. METHOD OF FORMING WlRE STAYS. APPLICATION FILED SEPT. 13,1915.

Patented NOV. 13,1917.

I Mot/"e13 such stays may be formed.

To a ZZ whom it may concern:

' Be it known'xthat I,"GJEAnLns"RiNnLsoiv; a citizen of the United States, residingat New York, in the county of New York and State of N ew'York, have invented new-and useful Improvements in the Methods. of Forming Wire Stays, of which the following is a specification.

This invention relates to the method'of forming wire stays and consists in certain improvements therein as will be hereinafter fully claim., v V

-In forming wire stays it has been common to. corrugate the wire giving. to the 'wire transverse -portions with connecting.

experienced in giving to the eyesa bend as desired, in that such a sharp'bend would necessitate reducing the size' of the pins over which the wire is bent beyond their capacity to stand the strain.

Corrugating wheels 5'are mounted on the shafts 4:. These corrugatingwheels-have a series of teeth which intermesh and the edges of these teeth maybe made assharp as desired 10 and the ends or and the corresponding grooves in the companion wheel-made as sharp as desired so as to give to thewire fed through the wheels a sharp bend. One of the shafts 4 is driven by a pulley 6 and gears 7 communicate the movement from one shaft to the other.

The Wire 8 is fedthrough a guide 9 and into these corrugating. wheels. It. comes from' them with sharp bendshaving the transverse portions loops 11. The wire then passes to the compressing rolls 12 being turned a quarter turn in passing from the 7 METHOD FtoRMaw;istsTrgs.? If;
