Abstract

122,470. Groesser, J., and Ley, E. J. Jan. 23, 1918. Sawing and like cutting; work-holders.-A machine for cutting or dividing diamonds by means of a revolving dish comprises a vertically movable carrying frame located above the saw and supporting a vertical carrier rod, the diamond being held between the arms of a forked member which is so mounted on the carrier rod that the diamond is adjustable either along, or transversely to, the plane of the saw or angularly. In the machine shown, the saw 4 is axially adjustable in bearings 2 which may be adjusted transversely by a screw 5. The diamond is held between clamps 24 carried by relatively-adjustable arms of a fork member 20 which is laterally and angularly adjustable in a hinged, angularly-adjustable clamp 19. This clamp is pivotally connected by a screw 18 to a carrier rod 14 which may rotate about its axis for adjustment, and is connected by a cross-bar 13 to slide-rods 11 coupled by a cross-head 12. A lever 25 connects the cross-head 12 to a pivotally-adjustable weight 26 which exerts a downward pressure to feed the diamond to the saw. Guides 10, 15 are provided for the rods 11, 14. The diamond is arranged with the grain parallel to the direction of its advance on to the saw.
