A. Model Triple M, c. 1894. Uses the largest style movement made for Yale by the E. Howard company, designated 'M' and signed by the company on the front movement plate. This size movement made and signed by E. Howard are fairly rare. The Howard movements had the 'M' designation on the dial. Only 200 of these large-scale movements were made by Howard before they went out of the time lock manufacturing business in 1902. Nearly all time locks using this size movement were equipped with later Seth Thomas equivalents that looked nearly identical but lacking the Howard signature logo on the front plate. The small circular flag with the word "OPEN" was an optional feature and what Yale called a "throw off" device which kept the lock 'off guard' after the time locks had already been wound to the set time. The flag would show through the porthole to warn the user that the lock was off guard  and would disappear from the glass aperture when the lock was ready to go 'on guard'. Case door with first design version, the full window. Case #39, E. Howard movement numbers, 133, 138 and 150 with matching numbers on dials. file 104

B. Model Triple M, c. 1908. Same as 'A' but with later movements made by Seth Thomas, yet identical in the damascening but lacking Howard logo. Case has the Yale designated "wave bronze" design. Door is the early full window glass and has the safe manufacture's logo of "Remington and Sherman Co., New York and Philadelphia". The very interesting feature of these movements are the dials. They lack all references to Yale and Stockwell's patent name; with only the inscription "Patented July 19th, 1892". All other examples of Yale movements from their very first Model #1 to their modern examples have the company name and location as well as the reference to the Stockwell patent along with the identical language as to the patent date that appears in this example. (Only post 1950's examples eliminate the Stockwell and patent date references). The serial numbers rule out a manufacture of post 1900. Etched on the glass door is REMINGTON AND SHERMAN CO. NEW YORK AND PHILADELPHIA. Perhaps the safe manufacturer wanted to also take credit for the time lock with agreement by Yale, but I've never heard of such an arrangement. Two photos show the separate heavy housing that the movements are mounted into. This housing is then mounted between springs into the actual time lock case. All Yale time locks used this anti-dynamite contrivance. Case #198, movements consecutively numbered 1971, 1972, 1973. file 54

C. Model Triple M, c. 1915. Uses the largest style movement made for Yale by the Seth Thomas company, designated 'M'. Nearly all time locks using this size movement were equipped with later Seth Thomas equivalents that looked nearly identical but lacking the Howard signature logo on the front plate. Case having the 'wave bronze' design and the door by this time using the half window design to eliminate the hazard of winding holes through the glass. This particular lock came from the Rockford Trust Building, Rockford, Illinois. Case #758, movement numbers, 5955, 5956, 5957. file 1

D. These are largest and smallest size movements Yale used in their popular 'coffin' style design; designated 'M' and 'T' (massive and tiny?). These movements were made by E. Howard, however, Seth Thomas also made movements as exact replacements. Yale's most popular size, known as 'L' is midsize between 'M' and 'T'.

E. Vault door by the Remington and Sherman Company. This example does not contain a time lock

F. A large round vault door equipped with a Triple M.
