Mosler Safe Company, Hamilton,
Ohio - 3 movements, Type 1



A
A. Type 1, 1916. This is an early example from the Mosler Safe
Company. It should is not to be confused with
Mosler Safe and Lock Co. which was a
different company but still connected with the Mosler family and produced
two models in 1887 after their purchase of the patent rights from
Beard & Brother that
same year. Mosler Safe Company's first offering was a
four movement model
that featured this same gold-plated door with a crackle jewelling finish and
this is the distinguishing characteristic for a Type 1.
The three movement was introduced around the same time. This feature was
used only for one year and by 1917 was replaced with a less expensive smooth
bronze finish similar to that of the three movement in example C. Unlike the
earlier incarnation of this company, the Mosler Safe Company used production
pocket watch movements bought from other watch suppliers. This author knows
of three movement suppliers that were used throughout the life of the
company until it was sold by the founding family in 1967 to American
Standard Companies. The first type used was an 18 size Model #4 movement
supplied by the Illinois Watch Co., Springfield, Illinois and is illustrated
above.
Waltham Watch Company, Waltham,
Massachusetts using their size 16 movement was substituted in 1933 after the
Hamilton watch Company took over Illinois Watch Co. Sometime in the 1950's
Mosler turned to the
Recta brand of watch movement made by Muller and Vaucher,
Switzerland and continued with this until production ceased in 1967. Around
this time Mosler as well as most US time lock makers had turned to Swiss
imports.
No production records exist for this model of Mosler time lock,
but it is thought that about a hundred were made. The case numbering appears
to have been initiated at #4000. It is unknown how many,
examples survive, see photo below for a second example in situ of
Cannonball Safe. 5 7/8"w x5"h x 2 7/8"d. Case#4080. file

B. c. 1918. Around 1902 with the sale of E. Howard & Co. to the
Keystone Watch Case Company, E. Howard exited the time lock business.
Therefore, the time lock companies that used E. Howard shifted to Seth
Thomas movements. Mosler, however, did not begin manufacture until 1915 and
chose 18-size Model #4 pocket watch movements supplied by the Illinois Watch
Company. The movements had a separate crystal covering the watch movements
much like on a conventional pocket watch providing exceptional protection
from contamination compared to other time lock movements.
Bankers Dustproof Time Lock Co. was another
company that used movements supplied by Illinois Watch Company. This was
probably not coincidental since Banker's disappeared as a brand in 1915 and
Mosler Safe Co. appeared in 1916 based on designs very similar to that of
Bankers. After 1932 Mosler switched to
American Waltham Co. 16-size pocket watch movements. Mosler Safe
Co. was the result of a series of consolidations of earlier companies
including Mosler Safe and
Lock Co., Mosler Bahmann and Bankers Dustproof Time Lock Co. That
company emerged in 1917. In addition to the protection given the watch
movements by a glass crystal fitted over them, the movements can be wound
without having to open the door by sliding the lever to open the winding
holes. These features result in Mosler movements being some of the best in
surviving condition . This lock as well as the example above dogged the bolt
work via a lever attached to a right hand lever located on the outside of
the case to the right. In the first year of production the case had the
crackle finish door with satin bronze sides. By 1917 the door was changed to
the same satin bronze finish as the sides, but this design was short-lived
and only lasted a few months making this a fairly rare example. That year
Mosler replaced the satin bronze with a satin nickel finish which remained
until the change to the plastic front cases beginning in the 1950's. 5 7/8"w

C. c. 1930's. By this time the style in the time lock industry
began to favor the art deco sleek satin silver designs that survived past
WWII. And so Mosler only had their crackle finish door and bronze satin case
design for about a year or two before moving to this case color. This
example is equipped with a longer duration 120 hour movement set. 5 7/8"w
x5"h x 2 7/8"d. Case

Illustrated above is one of the patents stamped into the door of all
Mosler time locks. The second picture shows Mosler's sophisticated dual
spring suspension system. Most other makers, if they used a spring system
used this for the movement plate only and the time locks were firmly secured
to that plate. Mosler used a second spring set to fasten their movements to
the spring-suspended movement plate. The decorative bolt escutcheon located
on the right side of the case in the first illustration was never
incorporated in their production models; only a round hole in the case.

The first photo shows a fairly complex bolt dogging lever system compared
to most other makes. The next photo shows the dual spring suspension system
as illustrated in the second patent drawing above.

D. c. 1960's. This time lock case style was meant to convey a
sense of impregnability similar to
Yale's model M33. 6"w x 5"h x 3"d. Case

Below are two Mosler vaults with a Mosler triple movement time lock
similar to example 'C'. However this model
dogged the bolt work in the more conventional fashion by blocking the
release bolt directly through a hole in the side of the lock. The three movement size was
appropriate on the first square door, but one might expect that a large
round vault door as depicted below would have had a four movement lock.
Although the need for one was superfluous. The probability of a three
movement lock failing was as vanishingly small as a four, and there was no
greater need for the pulling power of an extra movement to release the bolt
work. However, a four movement lock would have 'looked right' to provide the
appropriate drama suited to the door and would have been the correct size.
This was pure aesthetics and marketing as historically was much of the time
lock as well as the safe and vault business, as well as the architectural
design of bank buildings - all to convey solid, safe and dependable imagery.
Now look at the third photo at the bottom,. This is the same type of lock as
on the huge round vault door, but is located in a very small Cannonball type
safe, probably no more than two thousand pounds (look at the hand next to
the lock on the right) compared to the ten ton door.


In this photo one can see that there was something that was rubbing up
against the door of the time lock and rubbed a deep groove into the surface
after repeated opening and closing of the door. The door turns to open and
close rather than in the conventional way of a rectangular door. Perhaps the
combination knob seen in the first photo. It does appear that the Mosler is
quite large for the door upon which it is mounted. I have never seen this
Model of Mosler mounted into a screw-door Cannonball safe.
