Screw-cutting machine.
This model represents a screw-cutting machine, patented in 1856, for cutting screws by hand or power.
The dies are held in a clamp which slides freely on two fillets, one on each side of a trough. The clamp is provided with a screw and a graduated scale for closing and setting up the dies, and a lever and latch for quickly opening them. The rod or bolt-blank to be screwed is held in a pair of jaws like a lathe chuck, and is caused to rotate. The machine can also be used for tapping nuts, a cross bar with a square recess or socket being then used to hold the nut stationary, and the tap being held by the jaws and rotated.
