where the pin comes, and the Aider giving a little way for the
thicknefs of the aforefaid key, the groove juft mentioned admits
the key over the head of the pin P; then, when the key is drawn
back again, P moves toward A by the center C ; and S, the ftop
which projects beyond the till, is by this mean drawn within.
B is a plate fcrewed on to the till to keep the ftop firm. Again,
when the till is down to its place, it is neceffary that it fliould be
flopped there alfo, as has been already faid. The apparatus for
this is fhewn at No. 3, wdiich is a different view of the fame lock
as at No. 2. 1,2, 3,4, is fuppofed to be a part of the bottom,
not of the till, but that whereon the machinery is placed at
No. 1. t s is a kind of trammel with flits in it, moving on a
center at J. A pin is fixed to the bolt of the lock, and there
being a paffage for the pin cut out of the lock-plate, as fliewn
in the defign, this pin moves up and down, according as the
key is turned, a is a kind of lever, with two arms, moving at
the center a. c c are ftaples which are fattened to the under-
flde of the till, and as the bolt of the lock fhoots downwards,
the trammel t j throws the arms of the lever out of the ftaples
which are fixed to the underfide of the till; by which means
the till is relieved, and can then be raifed by drawing out the
fly-bracket. And here the workman muft be careful to ob-
ferve, that when the bolt b, No. 1, is fhot, as it now appears,
the till is always relieved, and the bracket at the fame time has
