Abstract

10,045. Liddle, J., [Morgan - Gardner Electric Co.]. April 28. Coal-cutting machines. - A pickpointed or chiselpointed bit for coal-cutters of the chain type is formed with a shank portion having two parallel faces 8, 9 and converging s i d e s 10 receding from the front face 8. The socket 12 in the link 13 is made of corresponding shape, and is provided with a stop 14 and setscrew 15. The socket may be arranged so that the bits project laterally in a plane parallel with the sides of the links or obliquely as shown, in which case the point of the bit preferably extends beyond the outer side 16 of the lug 17.
