Consolidated's Dalton Triple Guard Time and Permutation Combination Lock. c. 1888. This lock was a later competitor to to the early single case designs of of Sargent and Yale that contained a time and combination lock which were available from 1876 to 1885. The Triple Guard was the most complicated and expensive time lock ever made at $750 this amounts to $15,000 today. It featured the unique Milton Dalton patented single tumbler combination lock that could be opened with with a combination of anywhere from one to six numbers, set with a lateral lever across a single tumbler disc; controlled by a Dual Guard lock (the time lock portion). (1) This lock shows a an abundance of the special ivy engraving and pictorial designs sometimes used in Consolidated's locks. No other example shows the detail and variety that this lock has. Judging from this as well as other lock examples the engraver, or his employer, had an affinity for the outdoor activities of sailing and hunting (perhaps especially duck hunting since one photo above shows a duck within a heart shaped medallion?) Only two examples of this lock are known and due to its rarity and complexity is one of the more expensive examples of collectible time locks. 8"w x 7 1/4h x 3 5/8"d. Case #8, movement #615. file 136

Below is a photo of the only other known example of the Dalton Triple Guard from a private collection. Serial #2
