1914 Northampton County Jail Locking Mechanism
cases were opened to view the inner locking mechanisms for three
cells. The jail has 4 sets of these on two floors. This was "cutting
edge" technology for its day. This type of locking mechanism was used
about 14 years later at the Indiana jail where John Dillinger escaped
and 20 years later at Alcatraz. The last slide at the bottom of the page shows the cell locking controls that would allow for 1, 2 , or 3 cells to open separately or all at one time.
