Mosler Lock Co., Covington, Kentucky & Mosler Safe Co., Hamilton, Ohio - 2 movements, page 2
A. Model 'Do-All'. c. 1940. A hybrid lock that combines a key lock and time lock. Delayed period may be set 20, 40 or 60 minutes. The re-lock feature may be set or left off as desired (note lever on lock right hand side). If the locking lever is set at "on" and the door is not opened within 10 minutes after the delay period expires, the lock will re-lock until another delay period is set up and expires. A time lock containing a combination (instead of or in addition to a key lock) and time lock is called a timebination lock (see below) and a Sargent & Greenleaf model here. Earlier Mosler locks used a modified Illinois Watch Co. 18-size, Model #4 pocket watch movements. After 1932 Mosler switched to the American Waltham Watch Co. 16-size pocket watch movement (used in this example). All of these movements were covered with an attractive domed crystal which kept the movements protected from the dust and elements. A far better system than movements in other time locks that were exposed to the elements every time the time lock door was opened. B. Model KCDC. c. 1940. Is a timebination lock. This unit features a fixed 20 minute delay that is automatically set when the the bolt is engaged and the combination knob turned clockwise one turn. This lock, in contrast to the 'Do-All' model, requires no winding. The action of cranking the combination knob will wind and set the time locks in motion for the twenty minute period. Contains two modified American Waltham Co. 16-size pocket watch movements. file 52 C. Manufactured in the 1950's. By this time Mosler had switched to Swiss made movements, but they still had the same body configuration as well as the glass watch-type crystal over the movements. This was a short lived transitional design. D. Manufactured in the 1960's after the acquisition of Mosler Safe Co. by Chubb. Uses Swiss made movements which now mirror the same body design as those used in the contemporary Yale time locks. file 36
