The Spool-O-Wire weighs 10 pounds with a full spool and measures 6.625" W x 10" L x 4.25" H (lever when fully extended adds 5" of height). This was designed to bind from 2 to 40 sheets of paper at a time. The wire used was a spool of special grade stitching wire measuring 1250 feet and would make upwards of 15,000 staples. The operating parts of the Spool-O-Wire were made of tool steel. The handle was nickel-plated. According to a 1916 article “each machine is caused to make and clinch at least one thousand staples, as a test, before shipment.”
The Spool-O-Wire was a product of Hutchison Office Specialties.
