The main driving pulley 7 revolves the roller 8 which is preferably fluted circumferentially so that the shell fragments are broken rather than pulverized.

Having now fully ascertained the nature of my saidinvention, what I claim as mine and desire to secure by Letters Patent, is:

In a combined crushing and separating machine having a trough shaped chute in which a transverse .circumferentially fluted roller revolves the combination comprising, a yieldable base that portion of the chute below'and opposite the said roller whereby a specially hard substance may depress one portion of the chute base without depressing adjacent portions, a resilient member supporting the yieldable portion of said base, an oscillating .baflie plate positioned across the base of saidchute and having the form of two converging; curved plates each with a double hinge adjacent the side of the said chute whereby the crushed material emerging from the roller may pass below the bot tom edge of the battle and the larger por-. tions may be deflected to an exit by the cur vature of the said baffle plates.

The roller is carried by a bearing 16 at each side and fitted with means for regulating the pressure exerted by the spring 17. These may be of any usual form and call for no special comment.

The angular and curved bafile 18 is located at a suitable distance, beyond the roller 8,

this consists of a flat plate normal to the surface of the chute and presenting a pair of curved sloping surfaces to all the descending material discharged from the roller 8.

The lower edge of the bafile 18 does not rest upon the surface of the chute except intermittently at points of support, but is dis tanced therefrom by a narrow aperture suf- .ficient in width to pass the shell fragments rapidity ,of the process by v preventing pos-
