formed, to be particularly described and ascertained in and by the following
statement:

lever rivited on a piece of metal C working in sockets at the back of the
fastening.

metal C works acting on the spring to which the tooth A is rivited shewing the
position of the perforations for the tooth A and shank of the ring to pass

and when not required to be open can be pulled down without touching the
fastening and thereby secured.
