| C. A. Knowles - patent attorney
My invention is an improved machine for sharpening and shaping rock-drills and other tools; such as moils, gads, tools for channeling-machines, gadders, stone-cutters' tools, bits for certain forms of coal-mining machines, and the like. One object of my invention is to provide a machine which is adapted to first form and sharpen the edge of the tool and then shape and size the head or bit thereof without removing the tool from the machine, so that the operations of forming and sharpening the edge of the tool and shaping or sizing the head or bit thereof may be performed one after the other without removing the tool from the machine during the process and so that the tool is entirely finished by the machine. A further object of my invention is to effect improvements whereby the machine is adapted for entirely forming and sharpening the tool without cutting off and wasting any of the metal of which the tool is composed. A further object of my invention is to effect improvements in the construction of the die-block and dolly-holder, whereby the same are prevented from becoming unduly heated while the machine is in operation.
A further object of my invention is to effect improvements in the machine and in the die-block and dolly-holder whereby the die-block and dolly-holder are provided with a plurality of dies and dollies which may be of different forms and sizes, adapted for sharpening and shaping tools of various kinds and sizes, and which may be readily adjusted on the machine to fit the same for performing any desired variety of work. A further object of my invention is to effect improvements in the construction of the vise for clamping the tool while the same is being shaped and sharpened and in the mechanism for operating the vise. A further object of my invention is to effect improvements in the means for feeding the tool alternately to the dolly and to the matrix in the shaping and sizing die, so that the operations of forming and sharpening the edge and of sizing and shaping the tool may be successively performed by the machine. A further object of my invention is to effect improvements in the construction of the frame of the machine. A further object of my invention is to effect improvements in the construction of the slide and the fluid-pressure cylinder.
