Press Bar

A curved bar of iron, one end of which goes through an opening in the spindle, and is secured by a screw in general, but sometimes by a square iron bolt which goes through an opening in the end of the bar, and as there is a shoulder that abuts against the square part of the spindle, both these methods draw it tight up, and attach it firmly to the spindle; at the other end there is a long, thick, tapering, wooden handle, through which the bar goes, and it is either secured by a screw, or the bar rivetted at the end with a collar round it. The bar to screw the book press down with is also called a Press Bar.
