Patent ID: 8650760

Claim:
A blade mounting structure for a substantially U-shaped blade, comprising: a pair of contacts; a pair of cradle brackets, each cradle bracket mounted to a respective contact of said pair of contacts; a pair of slotted blade cradles, each slotted blade cradle having a slot therein, mounted to a respective one of said cradle brackets and laterally adjustable with respect to its cradle bracket so that blades of differing width may have a leg of a selected blade inserted into each said slot; each slotted blade cradle having a guide means for preventing rotational movement of each said slotted blade cradle with respect to its cradle bracket; a clamp member for each slotted blade cradle, each said clamp member formed of a shape to extend over a portion of said slot for extending over the leg of the selected blade in the slot; a resilient means mounted between each said slotted blade cradle and its clamp member, each said resilient means tending to force apart its clamp member and its slotted blade cradle, and tending to force together its slotted blade cradle and its cradle bracket; means for tightening each said clamp member against its slotted blade cradle and against its resilient means for clamping the leg of the selected blade in said slot and preventing movement of its slotted blade cradle with respect to its cradle bracket; wherein loosening of each said tightening means enables the lateral adjustment of its slotted blade cradle with respect to its cradle bracket and separation of its clamp member from its slotted blade cradle for insertion of the leg of the selected blade; and wherein each said cradle bracket includes a block having an elongated T-slot therein for receiving a nut of its tightening means for the lateral adjustment of its slotted blade cradle.
