My features of invention are illustrated in connection with an ordinary gyratory stone crusher comprising, for instance, a main frame or shell D andD', the section D having a spider B mounted upon it, and the section D having an inclined diaphragm B" constructed within it. Within this shell or frame is a gyratory shaft A carryinga crushing cone A; said crushing cone operating within a crushing concave A, and the gyratory shaft having its lower end fitted in an eccentric box A and said eccentric box-being operated by gearing as A and A Myimproved form of hopper is constructed I as follows: It consists of an outer'main hopper 0 andan inner auxiliary hopper O.

The flare of themain hopper is on the same incline plane as the'greater portion of the flare of the inner auxiliary hopper. The inner hopper fits the inner diameter of the cylindrical part of the main hopper, and therefore can beslipped down into the same and moved up out of the same. Its outer diameter is only slightly increased over that of the spider D upon which it rests, as illustrated in the drawings. The main and primary hoppers thus constructed form as it were one continuous hopper. The construction is such, that the spider B with the inner auxiliary-hopper can 13o raised bodily up through the main hopper tal flange aformed on the upper edge of the section D of the shell orframe. And by this means access can be had to the crushing head and concave and other parts of the machine for repairs after the spider and auxiliary...
