A crusher with one stationary jaw and one movable jaw, the movable jaw is moved by a cam at the top of the jaw, in the well known manner of jaw crushers. The cam shaft is adapted to be driven with a conventional square drive lever. A dual purpose bolt, transversely behind and against an upper portion of the stationary jaw, serves as a re-active stop and as a pinch bolt to clamp the stationary jaw between the side plates. The upper ends of the front legs abut a lower portion of the stationary jaw, thereby serving as legs and re-active members for the stationary jaw. A transparent Poly-carbonate feed opening cover is secured to the tops of the side plates with magnets. |
