ABSTRACT:
A leaf spring spreader assembly comprising a tubular frame (20) having a V-shape with legs (22) extending in opposite directions from an apex (24) to a collar (30) welded to each of spaced ends with a screw (32) disposed in telescoping relationship with and extending axially out of each leg (22) to a plate (42) for engaging the end curl (34) of a leaf spring. A nut (36) has radial holes (38) for receiving a round rod to rotate the nut (36) for reacting with the collar (30) for moving the screw (32) relative to the frame. A bearing (40) is disposed about each screw (32) for transmitting thrust loads from and facilitating rotation of the nut (36). A tension spring (52) is pulled through the tubular frame (20) and connected to the second screw (32) and released to pull the inner ends of the screws (32) together to retain the nuts (36) in engagement with the bearings (40) to maintain the components together.
