Consolidated Time Lock Co., Cincinnati, Ohio - 3 movements
A. A rare triple movement lock made up of a composite of movements found in the company's standard dual and single movement models. Unlike other models that Consolidated made, this case has no patent dates and these movements are 78 hours in duration as opposed to the company's' normal 46 hour movements. Note the difference in the lever and dial pointer in the lower movement. The bolt release arm was altered to work in the new configuration. As a result, the original dial pointer was cut off and replaced with a separate one attached to the arbor positioned so as to indicate the correct time. This may have been an experimental or prototype model. There is only one other known example. file 103
B. 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. 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. 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
