Abstract

25,429. Clark, G. P. Dec. 7. Tools and tool-holders.-A hand or machine tool, such as a chisel, gouge, &c., has a detachable bit, with or without a shoulder, the shank of which is provided with a cylindrical projection to fit in a holder having a centre hole and dividing slit as shown in Figs. 1 and 3. The portion of the shank near the cutting-part is slightly enlarged and conical. In a modification, shown in Figs. 3 and 4, the shank has a portion cut out, leaving a space G into which a plug E, previously forced into the centre hole, enters. The plug may be formed with the shank as shown in Fig. 5. The bits may be removed by a wedge driven in the portion of the slit below the shank.
