| Additional Information: | A 'site file' titled Little Chute Locks and Canal Historic District exists for this property. It contains additional information such as correspondence, newspaper clippings, or historical information. It is a public record and may be viewed in person at the Wisconsin Historical Society, Division of Historic Preservation-Public History. Photo Code: FCS 5/18. This structure is unique to the Lower Fox System because it actually consists of two traditional locks that are placed back to back. Constructed between 1874 and 1877, the locks are oriented on an E/W axis. The lock chambers and adjacent wingwalls are comprised of quarried limestocne blocks. The sides of the upper lock are capped with concrete coping and a pipe railing, while the sides of the lower lock have quarried stone coing as well as a pipe railing. Each of the six lock gates are constructed of squared wooden timbers that are laid horizontally atop one another. Adjacent to each gate is a concrete platform that contains a tripod. A vertical shaft extends the height of the tripod. A handle is fixed to the top of the shaft, while the bottom of the shaft contains a gear that drives a horizontally placed spar, the end of which is attached to a lock gate. (It is a horizontal rack and pinion system). Depending on which way the handle is turned, the spar is either taken in, thus opening the lock gate, or it is pushed out, in which case the gate closes. The 144.1 by 36.3 foot chamber of the upper lock is flooded by six butterfly valves that are set in the floor of the lock, three on each side, immediately upstream from the structure. As the valves are opened, water passes down into a culvert with a 90 degree turn, which then directs it under the upstream sill and straight into the chamber. Each valve is adjusted by a geared mechanism that sits in the lock's coping. A metal shaft connects the valve to the adjusting mechanism. The upper chamber is discharged through the same type of butterfly valve system, because it is that discharged water that floods the 146.5 by 35.4 foot lower chamber. That chamber is discharged by six small butterfly valaves found at the bottom of the two downstream gates. There are three valves per gate. These valves are operated by the levers atop each gate. The gates contain a cat-walk that facilitates moving from one side to the lock to the other. The upper lock provides 10.4 feet of lift, while the lower lock provides 10.9 feet. Combined, the two locks enable crafts to move from 675.3 feet above sea level upper pool to the 652.3 feet above sea level lower pool. THIS STRUCTURE IS RELATED TO THE LOCK SHACK AND THE LOCKKEEPER'S HOUSE. |
