The improved leaf or sheet constructed according to my invention is of an extremely aim is and inexpensive nature and is especiali; well adapted for use by reason of the uniform alinement of the edges of the sheets attained when the leaves or sheets are in lace withinthe binder, and it will be obvious mm the above description that the imgrovedleaf or sheet is ca able of some modi- 'cation without .materia departure from the principles and spirit of the invention-and for this reason I do not desire to be understood as limiting myself-to the precise form and arrangement of the improved leaf or sheet herein set forth in carrying out my invention aving thus described mi; invention what I claim and desire to secure y Letters-l atent 1.
