A, B, C & D. Model Triple L . These locks used the medium sized Type L movement by Seth Thomas and were by far the most common sized of the coffin style movements used by Yale and this model had the largest production in the Yale line. The model L was used with automatic bolt motors so no bolt work was in the case; only the release levers within the bottom bulge of the case to actuate the bolt motor. Lock A, with the eyelets though the glass was the first and rarest version. Then came B that had the them through the door. Lock C has the later brass-swirled case design adopted around 1908. Lock D has has a more complex release bolt and later Swiss movements with optional magnifiers in an older pre 1908 case. These Swiss movements are also used in many later plastic-fronted locks that had the magnifiers built in to the front plastic piece. This was one of the most successful time lock designs made by Yale with over sixteen thousand versions of this lock made between 1892 and 1920 making this the largest production run of any time lock of the era.

The last four photos show typical installations of a the model Triple L . First in a Herring-Hall-Marvin safe from the early 1900's. This company was an amalgamation including the earlier company of Joseph Hall from the late 1880's. A medallion of Mr. Hall's profile can be seen here. Second in a Mosler cannonball type safe. Notice the beautiful floral decoration surrounding the lock. Cannonball type safes were one of the most popular models made and many time lock companies made locks that could work in this type of safe such as Diebold, Banker's Dustproof, as well as Yale's Y-361 and LS31 .
