Figure 17. This is the drawing of the new remontoire lock/release arm along with the finished part. This has two arms as compared to one one giving a periodicity of 30 seconds instead of 60. Since the physical demands on this part are small the arms are kept slender, in fact the hub and arms were nearly a direct copy of the driving wheel opposite this on the same arbor (see below). This seems to fit nicely with the design of the two existing wheels being the same circumference. Research has turned up another Wagner tower clock in a museum in France that has a similar 30 second remontoire design.

The advantage of this over the former design is the elimination of speed variation of the flyfan and remontoire during the recoil cycle. This is due to the fact that a single arm cannot be balanced relative to its circular movement. The redesigned lock/release wheel is symmetrical.
