Claim 1
Independent Claim
177 words
An improved device for maintaining books in opened condition for reading comprising: first and second elongate elements mutually pivotally interconnected at a single point at one end thereof; each of said elements including an elongated portion commencing at said inner end and extending away from said single point a distance corresponding to approximately the width of a page of an engaged book, and an open ended inwardly facing resilient loop formed integrally with said first portion and forming a means for resiliently clamping a group on pages and underlying portion of the cover of one side of a centrally disposed binding of an engaged book in such manner to permit the uppermost page to be readily moved outwardly from one of said open loops with the completion of reading of said page to be engaged beneath the oppositely disposed loop; said second element being slightly smaller in overall dimensions to permit said second element to be pivotted about said single point relative to said first element to be nested within said second element when not in use.
