a stanley yankee screwdriver

an antique push drill

Stanley Yankee No 130A, spiral or ratchet screwdriver was spring loaded and when the handle was depressed the spiral section passed around a fixed lug and into the handle with a twisting motion. The lug could be reversed for withdrawing screws.

In addition the driver could be locked inside the handle and it could be used as a normal ratchet screwdriver.

I have said before that this tool must have been responsable for more marred work and damaged fingers than any other tool. The reason being that when these things were in vogue the screw heads were still slotted. The Phillips head was not in common use. By were we glad to be able to retire the old Yankee and get a proper screwdriver gun.

The predecessor of the pump driver, by some few hundred years was the pump or push drill on the right. The tool was held firmly and the centre handle was pushed downwards imparting the drilling force.
