To all whom it 'may concern:

Be it known that I, WILLIAM W. HARD- ING, of the city of Philadelphia and State of Pennsylvania, have made a new and useful Improvement in Machinery for Perforating or Deeply Indenting Newspapers, Magazines, Pamphlets, &c., so that Their Folds May Easily be Torn; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l shows a view of my arrangement. Fig. 2 shows the bar A A detached,

The nature of my invention consists in providing a bar A A which is of a height a little greater than that of the type, with a series of sharp points of anydesired shape. This bar is then placed in the form, (the teeth projecting a little above the surrounding type), at such va place as it is desired the perforations should be in the paper. Vhen the impression is taken these points. will perforate or deeply indent the paper.

The object of this invention is to perforate a series of holes in the folds of newspapers, pamphlets, books, magazines, etc., whereby they may be easily separated.

Having thus described my improvement what I claim as my invention and desire to secure by Letters Patent is- The combination of the bar A Aprovided with a series of teeth, with the form so that when the impression is taken these sharp points will perforate or deeply indent the paper, substantially as herein set forth.

WM. W. HARDING.
