Bullock press

A new rotary self-feeding and perfecting press, widely differing in its principles of construction from all other machines, as the annexed illustration shows. It is fed from an endless roll of paper, prints both sides at the same time, and cuts up the shets to the proper size, placing them on the delivery-board in a pile. It was invented by Mr. William Bullock, an American, and was first introduced into Europe in December 1869.
