Description
При выборочном подсчете табличного материала дл облегчени этого подсчета приходитс цифры некоторых столбцов прикрывать, оставл открытыми только те, которые подсчитываютс . Дл облегчени таких подсчетов и предназначена предлагаема линейка, снабженна по своим кромкам шарнирными зубь ми.When selectively counting tabular material, to facilitate this counting, the numbers of some columns have to be covered, leaving only those that are counted open. In order to facilitate such calculations, the proposed line is designed, equipped with hinged teeth along its edges.
На прилагаемом чертеже фиг. 1 изображает предлагаемую линейку - вид сверху, фиг. 2-то же, вид сбоку.In the attached drawing of FIG. 1 depicts the proposed line - top view, FIG. 2 is the same side view.
Линейка по одной своей кромке или по обеим кромкам несет шарнирно укрепленные на ней мелки зубь /, которые могут быть приводимы в одну плоскость с телом линейки или откидываемы на тело линейки.The ruler along one edge or along both edges carries small teeth hinged on it, which can be brought in the same plane with the body of the ruler or can be folded back onto the body of the ruler.
Путем отгибани зубьев в требуемом количестве в определенных местах кромки линейки возможно, при накладывании линейки на таблицу и при поперечном ее перемещении по таблице, выдел ть цифры тех столбцов, по которым требуетс произвести тот или иной подсчет.By bending the teeth in the required amount in certain places of the edge of the ruler, it is possible, when overlapping the ruler on the table and when it is transversely moved across the table, to select the numbers of those columns for which one or another count is required.
Предмет изобретени .The subject matter of the invention.
Линейка дл выборочного подсчета табличного материала, отличающа с тем, что по своим кромкам, одной или обеим, она снабжена шарнирно к ней прикрепленными зубь ми /, соответственным откидыванием которых на тело линейки возможно, при накладывании линейки на таблицу, выдел ть цифры подлежащих подсчету столбцов.A ruler for selectively counting tabular material, characterized by the fact that, by its edges, one or both, it is provided with hinged teeth attached to it /, by appropriately tilting them onto the ruler body, it is possible to separate the digits of the columns to be counted .
