A. Model #6, (later no. 6201), c. 1910. This model was produced in three slightly different sizes from 1900 through 1929 with a total production of about two thousand. In the interest of trying to reduce size, this model was Sargent's first to abandon the gravity-operated bolt, commonly known as a 'cello bolt' because the early designs looked much like that stringed intrument. The new bolt was moved from the bottom portion of the case to the upper, and since it no longer relied on gravity for it's release function, it had to be biased with a coil spring that forced it upward to the locked position once the door's boltwork was in the shut position (that is withdrawn from the lock). The button located on the top of the lock, between the two movement dials was used to load the bolt spring. Since it could be used with the door closed, it was similar in function to Yale's Gesswein Attachment; allowing someone to activate the time lock, that is, to put in 'on guard' without actual access to the time locks. Of course in this particular lock it is irrelevant since the lock's door is a simple push button release. About 75 of the model #6 are known to exist today. This example is in superb condition; it has the rarer push-button door release as opposed to the small hand-cuff style lock. 4 3/8"w x 3 1/4"h x 2 5/8"d. Case #303, movement # 2884. From the Italia Bank on Broad Street in South Philadelphia. The last picture shows an advertising plaque for the #6 on a dummy box above the actual time lock. file 88

B. Combined time lock and combination lock (timebination). Purpose is the same as a time lock, but designed for short duration. Dual movements, 5 to 30 minutes maximum time delay in 5 minute increments. A small pin is screwed into the hole corresponding to the desired setting time. From a York safe. For an example of a combined key lock and time lock see the Mosler example. Another example of a modified time lock to deal with shorter inter-day time intervals is a small Yale make. file 96a

C. Model  6280. A modern version of the 6200 series. In the later half of the 20th century many manufacturers cut costs by dispensing with the metal door and replacing it with a screwed on plastic cover; often with integral lenses for easier reading of the dial. c. 1970's or later. file 60
