Hand Operated Jaw Type Ore Crusher – Grinder
That above, looks crazy, but this below IS Totally CRAZY!
Figure 66 shows the Taylor Hand Crusher. This consists of two jaws, one of which is stationary and one of which is operated by the hand lever. Both jaws are faced with hard white iron. The movable jaw has horizontal corrugations, so as to force the material to be crushed down at each stroke of the lever. This jaw moves in both a vertical and horizontal direction. The lever has a rubber covered hand grip, and a rubber cushion where it strikes the bed-piece, prevents jar and noise. 
The jaws are 3 inches wide and open 1¾ inches, so that a piece of material 3 x 1¾ inches can be crushed. Forty pounds of the hardest rock can be easily crushed, in one hour, to such a fineness that 20 per cent, of it will pass a sieve having 60 meshes to the linear inch (No. 60-sieve). The jaws can be so adjusted that all can be made to pass the above sieve. The crusher can be easily cleaned and kept in repair. It crushes much faster than a mortar, because the fine material drops out into the pan as fast as produced, and does not remain, as in a mortar, to deaden the blows of the pestle. This crusher is catalogued and may be purchased of any dealer in chemical supplies.
