Description: Patent for new and improved animal shears. This design is "to secure an equal wear of the teeth of the stationary and the revolving cutter-plates . . . whereby the instrument may be run double the usual time before it is necessary to grind the plates, and enabling the tool to be used as a right or a left hand cutter; also, to render the cutters separable without arresting the motion of the rotary blade . . . also, to provide means whereby the rotation of the cutter may be reversed . . . finally, to provide a simple device for throwing the miter-gears into and out of mesh" (lines 15-29).
