  • Patent number: 3981476
    Abstract: A spreader clip assembly which is designed for use in connection with a concrete wall form and cooperates with a she-bolt on one end of a tie rod in preventing inward collapse of the adjacent side of a concrete wall form prior to pouring of wet concrete between the opposed form sides. A washer which is loosely and telescopically received over the she-bolt bears against the outer side of the adjacent form side and is clamped thereto by a nut, while an inverted J-shaped spreader clip proper which is captured on the washer is movable by a compound angular swinging and sliding action between a locking position wherein it straddles both the nut and washer and assimilates any tendency for inward collapse of the adjacent form side, and an out-of-the-way position wherein it exposes the nut for manipulating purposes.
