Yale & Towne Manufacturing Co., Stamford, Connecticut - 3 movements, Type D & E
A. Type D, c. 1890. The company of E. Howard & Co. and Seth Thomas supplied nearly all of the movements for Yale time locks (until the 1950's when movements from Switzerland were used). An exception is this model which used a modified version of a pocket watch; size #14, model 84 movements by American Waltham Watch Co. Waltham was extensively used in Mosler time locks. This lock was designed to operate in the conventional manner, that is directly upon the bolt works of the safe. A stop pin, third photo, was featured on this version which allowed the user to bypass the time lock and allow the safe to be opened with only the combination lock. The movements were designed with anti-magnetic qualities - cutting edge technology for the day. Yale sold a total of 62 Type D's between May 1889 and June of 1892, fewer than 5 are known to have survived. 4.5"h x 5"h x 2.5"d. Case #36, movements #4658505, 4658556, 4658586. file #129
B. Type E, c. 1889. Same as model D except this was designed to be used with automatic bolt motors activated by the side pin as shown in the second photo. Yale sold a total of 139 model E's between May 1889 and June of 1892, fewer than 10 are known to have survived. 4.5"h x 4.5"w x 2.5"d. Case #6, movements #3509613, 3509767, 4527341. file 95
An interesting aside is the fact that both Seth Thomas and E. Howard were companies that made a full line of clocks and watches. From large tower clocks (for public buildings) to domestic clocks to watches as well as movements for time locks. Click here to see a medium sized Seth Thomas and Howard tower clock.
