Consolidated Time Lock Co., Cincinnati, Ohio - 3 movements, modular movement design
A. Harry Dalton type triple time lock, c. 1905. This design was adapted from a successful three movement configuration patented in 1904 by Consolidated's employee Harry Dalton for use in Ely Norris Co. safes and used Elgin Watch Company movements. It replaces the the limited three movement design described in the example above. Consolidated brought this design for use with automatic bolt motors to meet competition that was offered from Diebold at the time. (1). This example comes with its associated bolt motor, making it a rare combination. A version was also produced for conventional, manually operated bolt works. Consolidated ceased production in 1906, so while this style of lock is of a later vintage than those shown with the earlier Howard movements that have the horizontally mounted balances, (with the exception of the 3 movement shown in example A), there were fewer of these made making them quite rare. The first watch movements used by Consolidated were by Elgin Watch Co. in Illinois and can be identified by the white dials. Shortly thereafter, they shifted to using South Bend Watch Co. movements made in Indiana. Those used black dials. Time lock net 6"w x 3 1/2"h x 2 3/8"d. With bolt motor 6 1/2" h. Case #1440. file 150
B. 1905-06. Consolidated made only a few locks that operated directly upon the bolt work of the door. Their locks were mostly used with automatic bolt motors or in some cases operated directly on the combination lock by blocking the fence from falling into place should the correct combination be dialed in while the time lock was still on guard. The latter method was a fairly uncommon method of guarding the safe by any other makers. By far the most common was the use of an automatic bolt motor which would be tripped by the time lock or the use of a bolt dogging mechanism to block the bolt work from operating until the time lock went off guard. In this example an adaptor is mounted to the base of a two movement Consolidated time lock to allow it to operate on the bolt work in the conventional manner. This is evidenced by the hole in the base where the bolt work would slide through, last photo. By this time Consolidated had switched movement suppliers from Elgin National Watch Co. of Elgin, Illinois, to the South Bend Watch Co., South Bend, Indiana and the black dial format accompanied this change. 6 1/4"w x 4 1/2"h x 2 31/2"d Case #1710 file 207
Below is a photo of a three movement Consolidated time lock in a Cannonball safe. This lock operated directly on the combination lock fence, unlike the example above that dogged the safe bolt work and so did not have the base below the case.
