Abstract
The housing 156 has an elongated chamber 158 therein, which extends along a generally horizontal axis and has a port 160 at one end thereof, and another port 188 in the top thereof. A pin 140' is mounted in the chamber at the port 160 to be advanced and released relatively outwardly and inwardly of the housing along the axis when clamping and releasing the shoe. A coiled spring 168 is mounted in the chamber rearwardly of the pin, with a driver 170 interposed therebetween; and a lever 208 is pivotally mounted in the top port 188 of the housing on the chamber adjacent end portion of the pin, for rotation about a fulcrum 216 on the pin transverse the axis. Cam surfaces 178, 170 on the lower end portion 214 of the lever and the driver are cooperatively engaged with one another about the fulcrum to alternately compress and relax the spring, and advance and release the pin relatively outwardly and inwardly of the housing respectively, when the lever is rotated in the opposing angular directions about the fulcrum.
