Abstract
A device for securing the stationary jaw to the frame of a jaw crusher is disclosed. The device includes a crusher frame having top and bottom spaced apart cross members, a stationary jaw, and a threaded draw rod having a pair of inwardly moveable wedge members. The stationary jaw includes a top edge, a bottom edge, and a pair of interconnecting sides, and further includes a top lug adjacent the top edge and a bottom lug adjacent the bottom edge. The top lug is adapted for placement adjacent the frame top cross member, and the bottom lug is adapted for placement adjacent the frame bottom cross member. The draw rod is disposed such that the wedge members are positioned to engage the jaw top lug and the frame top cross member. Accordingly, in response to inward movement of the wedge members, the stationary jaw is progressively more firmly secured to the frame, thereby preventing undesired movement of the stationary jaw during operation of the crusher.
