Improvements in Erasers

25,674. Goldsmith, B. B. Nov. 10. Erasers; pencil and like holders.-In an eraser of the kind comprising a holder provided with ridges which are adapted to engage grooves or depressions formed in the erasing-material, the holder is formed of a pair of clamping-members with one or more ridges at their extremities adapted to engage grooves in the end or ends of the erasing-material. According to the construction shown in Fig. 2, the clamping- members 13, 14, secured by a rivet 15 or otherwise, are constructed with flanges abutting along edges 16 and are provided at each end and on both sides with ridges 17 so as to secure two erasing-bodies 10, 11. In the modification shown in Fig. 5, the clamping-members 20 are in the form of two tapering shells with semicylindrical ridged ends 22 engaging grooves 19 in the erasing-material 18, the shells being clamped in place by forcing them into a tapering handle 21. The ridges 22 may be replaced by studs or points fitting suitable depressions in the erasing- material.
