  • Jaw crusher with drop-in jaws
    Patent number: 4752040
    Abstract: A jaw crusher has converging and opposed jaws defining a space for passage of material to be crushed. An improved design for supporting the jaws in floating relation on a frame structure of the crusher includes: upper and lower elongated resilient members connected with the frame structure and upper and lower reaction members connected to each jaw for respective interaction with the elongated resilient members, the upper and lower reaction members being substantially diametrically opposed to each other for permitting oscillatory movement of the jaws while at the same time limiting travel of the jaws in all directions on the frame structure. The improved jaw with upper and lower reaction members as described above facilitates drop-in assembly of the jaws in the crusher.
