Abstract
422,737. Book-keeping. LUBBOCK, H. W. R., 66, Oriel Road, North End, Portsmouth. Jan. 13, 1934, No. 1286. [Class 16] [See also Group XX] For facilitating the cross-casting of items entered in columns the paper containing the items is mounted in a readily detachable manner on a board with the items to be cross-cast extending parallel to its top edge, and a strip, which is arranged to co-operate with the board to maintain one edge parallel to the top edge of the board, is placed thereon, the parallel edge of the strip being castellated so that the items to be cross-cast appear in the gaps. The strip provided with projections 6<a> and gaps 7 is attached to the straight edge of a T-square 6, the head of the square being provided with one or more parallel slots in which a strip 5 attached to the edge of the board 1 can engage. By providing a plurality of slots, the gaps can be adjusted to reveal any desired series of items. The paper strips, on which are the columns of figures, are mounted on the board 1 by perforations in the top edges of the strips, which engage over projections 4 on the board, when the strips are clamped in position by a hinged strip 2, provided with a slot to fit over the projections 4.
