I have a few T&S wall & mantel clocks that just strike the hour. Does any one have an idea when they started using the half hour strike feature? All of these clock, Ansonia, Atkins, EN Welch & Waterbury, have movements that are mounted with wooden blocks. As far as I understand it, the use of wooden mount blocks was discontinued some time in the 1880's. I have an 1874 (from a dated Jewelers label on the inside) Ansonia T&S Mantel Clock that is hour strike only. You would think that someone would have patent the hour and half hour count wheel. I am trying to get a better idea of when the were made.
