Repairing old safe doors
Following is the first of a couple of articles on repairing the hinges of older safes and vaults/bookroom doors.
The Forbidden Zone
THE FORBIDDEN ZONE LOCKOUT The setting of a combination number within the forbidden zone normally causes the mechanics of the lock to bind. The position of the third wheel fly won't allow the drive cam to throw the lock bolt. In other words, you can't lock the safe. That's a much better scenario than the opposite possibility. A lockout caused by the forbidden zone can be very complex!...Identification of Fichet Bauche safe ranges
I'm not sure where I got this from or how acurate it is, but I thought it may just be of some interest/help to someone, somewhere, sometime....Sentry Round Door Floor Safes
In 1930, during the Great Depression, John Brush Sr. and his brother-in-law, Willard Punnett, opened a small shop for the manufacture of safes. The "Punnett" safe had already been on the market— a very competitive market. These two unique men were looking for a new innovative safe designed to capture the buying public. Their idea was to produce a quality safe to protect against fire. They would endeavor to keep prices low through innovative engineering and production techniques. Experimental designs and testing produced a patent, one piece double-wall safe body with a resin-molded jamb. A special resin, when subjected to intense heat begins to melt and 'welds' the door and body to seal the interior – creating a heat barrier chamber. By sticking to a simple business formula — quality products at reasonable prices through innovative engineering — the Brush-Punnett Company began to thrive. They called their newly formed business, Brush-Punnett Company, Inc., which later became John D. Brush & Company. ...SENTINEL SAFE By Carl Cloud
My first exposure to the Sentinel safe door was by reading an article by Ken Dunckel that was published back in 1987. As Mr. Dunckel illustrates, the Sentinel locking mechanism was invented by an American named H.C. Whitall. The Sentinel was also referred to as the Whittall Tumblerless Safe. This round tri-bolt, lift-out door was designed for a safe body encased in concrete, either above or below floor level. It has a patent date of August 10, 1948 and was manufactured briefly by the Production Engineering Company in Berkeley, California. ...
