A Book and Document Protector
A device for punching identification marks in the pages of books or papers, may be made easily by setting pins into a small box filled with sealing wax. The box should be large enough to accommodate the desired wording without crowding, leaving about ¹⁄₄ in. all around the edge. Cut the box, which may be of cardboard, to a height ¹⁄₁₆ in. less than the length of a common pin. Mark the words to be punched on a piece of cardboard which just fits into the box. Punch holes along the letters and transfer them to the bottom of the box. Insert pins from the outside through the bottom of the box and permit their ends to come out of the holes in the cardboard guide. Cut away enough of the guide piece so that the melted sealing wax can be poured in, setting the pins firmly. The guide piece is then removed, exposing the ends of the pins about ¹⁄₁₆ in. If the work is carefully done they will be of uniform length. Place heavy blotting paper or cardboard under the page when using the punch.—D. G. Stevenson, Chicago, Ill.
