Abstract
A jaw crusher having device for securing the stationary jaw to the frame against side-to-side movement is disclosed. The jaw crusher includes a frame having a generally vertical base extending between a pair of spaced apart side portions, with each of the side portions including an angled ledge spaced from the base. A generally planar stationary jaw is mounted to the base and extends between the frame side portions, with the stationary jaw having a top edge, a bottom edge, and interconnecting side edges. Each of the stationary jaw side edges includes a beveled lug extending along its length. A pair of generally wedge shaped key plates are provided, with each of the key plates being mountable to an adjacent frame side portion and including a beveled first edge adapted to engage an adjacent beveled side lug of the stationary jaw. Each of the key plates further includes a second edge adapted to engage an adjacent ledge of the frame side portion. Accordingly, in response to downward movement of the key plates the stationary jaw is pressed generally horizontally against the frame base with the engaging beveled surfaces of the key plates and the side lugs cooperating to prevent side-to-side movement of the stationary jaw.
