    What I claim, and desire to secure by Letters Patent, is— The combination of a frame having a booksupporting ledge thereon, a hinged extension 90 attached to the frame and provided with a hinged prop at the outer end thereof, an intermediate piece between and hinged to said frame and extension, a rack upon the frameback, a casing having a spring therein at- 95 tached to and lying flat against the frame2 456,089 back, a weighted index-pointer and holder extending across the front of the frame, and a cord connected at one end with the spring and at the other to the pointer, whereby the 5 latter may be placed and counterbalanced at different heights and the device reversed with said prop and extension folded back so that the frame may be used as a slanting desk. In testimony whereof I affix my signature in presence of two witnesses. HENRY J. HARRISON. Witnesses:Frank A. LaBanc, J. E. Sedgwick.
