Description
Friedrick's patent "consists in certain improvement upon the metallic seal... The seal, as patented, shows a shackle-wire with a soft-metal button constructed with two heads or disks connected by a shank or stem, and so arranged that when the wire is wrapped or twisted around the stem and the edges of the disk compressed into a single thin milled flange, the latter prevents the opening of the two disks without detection." (Patent Number 176,290)
