The patent was granted for improvements to the key and mechanism that included a second set of wards (or bits) on the side of the key that, along with the regular bits of the key, act on a pair of interlocking levers to open the lock. As in earlier Eagle designs, there are six levers, three that are acted on by each set of bits on the key. Prior to this invention, a double-bitted key was used to open this type of mechanism. The end of the shackle has a notch in each side that engages with the levers. It was felt that brass locks provided more safety, so they were usually used for securing registered mail.
