Specification forming part of Letters Patent No. 131,412, dated September 17, 1872.
To all whom @t may concern:
Be it known that I, FLORIAN SGHAUER, of the city of Dayton, Montgomery county, Ohio, have invented a-new and useful Improvement in the Construction of Noiseless Slates for Schools; and do hereby declare that the following is afull, and accurate description thereover the corners from side to side, thus adjusting the bands upon either side of the slate, as may be desirable. The bands being kept on the under side of the slate no noise is made by taking up, laying down, or rubbing the same upon the desk or other hard substance. The` elastic bands c c may be used for book-straps to hold together books in carrying to and from school.
What I claim as my invention is- The application of the elastic rubber bands c c, pivoted at their ends to the slate-frame by means of screws or nails, so as to constitute cushions upon either side of the slate, and also serve as holders for'books and papers.
FLORIAN SOHAUER.
