Abstract: 355,354. Guide sheets for facilitating writing. BURT, F., 36, Howard Road, Southampton. May 24, 1930, Nos. 16058 and 22785. [Classes 16 and 146 (ii).] Means for facilitating the teaching and learning of writing, shorthand, and languages, or for repetition writing as an aid to memory training, comprises in combination a primary sheet or sheets of paper or other material furnished with a plurality of slits or apertures and a secondary sheet having one or both ends shaped to facilitate its entry through the slits in the primary sheet or into a pocket between the sheets constituting the primary sheet, adapted to be combined together in such a manner as to provide a plurality of alternate strips of the primary and secondary sheets. The primary sheet 23, Fig. 1, is furnished with a plurality of parallel slits or narrow openings 25 and through which the secondary sheet 24, provided with a shaped end 24*, is threaded as shown. Symbols, words; sentences, &c. to be translated or copied on that portion of the secondary sheet exposed between the slits 25 are written, printed, &c. on the parts of the primary sheet above the slits 25. A fresh surface can be exposed between the slits 25 by movement of the secondary sheet 24. In the modification shown in Fig. 15, the primary sheet is composed of two separate sheets 26, 27, or a folded sheet, joined together along two opposed margins 38, and both sheets may be provided with slits or apertures 28 which may be coincident or in staggered relationship with each other and may be of different widths. Bars or strips 29 between the apertures may be joined together by strengthening strips 31. One or both of the primary sheets 26, 27 may be furnished at one or both ends with parallel slots 32 or apertures or both, through which the ends of the secondary sheet 24 may be held, positioned, or manipulated. The slits 28 in the primary sheets may be shorter than the width of the secondary sheet 24 so as to provide a narrow marginal strip at each end of the slots which acts as a guide for the edges of the secondary sheet 24. The matter to be copied appears on the strips 29 between the slits 28 and entries may be made on both sides of the secondary sheet 24. Copybooks.-The primary sheets 26, 27, Fig. 15, are made up into book form such that the lesson to be practised is contained on the face of each leaf, and when the end of the book is reached the book is reversed and the lesson continued, on the reverse side, working towards the beginning of the book. When the lesson has been completed in both directions, the secondary sheet 24 in all the leaves or primary sheets may be moved to present a clean portion beneath each line of the written or printed matter on the primary sheets. In a modification the primary sheets may be composed of two sheets as before but with apertures in only one sheet, and in another form a second apertured sheet may be attached to the reverse side of the plain sheet, in which case two secondary sheets would be required for each composite leaf of the book. The book may be interleaved with unapertured plain or ruled paper or blotting paper, and the apertures in the primary sheets may be arranged either longitudinally or vertically. One of the sheets 27 of the composite primary sheet is formed larger at its upper end than the sheet 26 so that when a plurality of such composite sheets are stitched together along this edge, the upper edge 40 of the sheet 26 is left free to be lifted up for adjustment of the secondary sheet 24.
