History of the Typewriter

—228— Fig. 162. by means of narrow ribbon, wound on two spools and passing through a vibrating ribbon guide, which also serves as a type-bar guide, so securing due alignment. The paper fingers are adjustable to any width paper, and are so con- structed as to yield to the pressure of several thicknesses when carbon work is required. The scale is in front of the framework, and it will be seen from the illustration that the margin stops—one on each side—can be set from the front of the machine. On the paper shelf is an adjustable guide, securing an even margin as well as perfectly straight feeding of the paper. The working parts of the machine are enclosed and protected from all dust, but this front cover is opened by the movement of the lever at the left front post. When this is down, the interior of the machine is at once accessible for cleaning purposes. At the left of the machine will be seen the tabulator, which affords means of writing in true columns according to an octagonal arrangement.
