A. Model - Type 1, c. 1895. This was the first type of lock introduced by Diebold. As with many of their other locks this company took case design to a high level. Diebold used an acid-etching method instead of the conventional milling technique to make their intricate case designs, which otherwise would be cost prohibitive. These cases were also gold plated. (see other two movement and three movement Diebold cases). These were made to coordinate with the rest of the design theme that would be found on the inside vault door surfaces. Imagine how beautiful this must have looked, industrial form morphing into art! These early models had no internal bolt mechanism, but used a bottom release lever. Usually this configuration would be used with an automatic bolt motor, where the time lock would simply trip this motor. However, in the case of Diebold it was used to simply move a lever that released the bolt works. This was possible for the firm as their locks were used with their safes and vaults so they could design the strength needed to move the bolt precisely to the time lock. This example has the very early 'rosette' logo on the inner case plate and earlier style floral design on the case. Equipped with signed E. Howard movements. In 1902, Diebold switched to identical looking, unsigned movements made by Seth Thomas. The case exhibits the very early movement-mounting design where the inner plate had three staggered pins that would only accept a certain mated movement so as to keep them in a particular order. The upper case lip also had numbers 1, 2, and 3 above each movement's location. In other words, these time locks did not yet have truly interchangeable movements. Later in the production run, movements became interchangeable, see example B, and the pins were removed, however Diebold did not remove the now unnecessary numbering on the upper lip. While the movements in this lock are not consecutively numbered, these are likely the original installed from Diebold since each movement is exactly 13 numbers apart from each other. Case #180, movement #610, #623, #636. file 5 B. Model - Type 1, c. late 1890's. Same model as above. The early rosette logo is replaced by the hand engraved patent date of May 22, 1894 on the inner case plate. This and the simpler 'X' deco case design became the standard motif for Diebold. Equipped with E. Howard movements. Case #2267, movement #5832, 5838, 5859. file 40 Below is a photo of a Diebold 3 movement time lock in a Diebold safe door. Another Diebold safe with a Sargent & Greenleaf lock of similar configuration.
