Description
Предлагаемое устройство дл определени скорости работы на пишущей машине, схема которого изображена на чертеже, состоит из гальванометра К, соединенного с зажимами динамомашины 3, приводимой в движение электродвигателем Г, батареи В, питающей электродвигатель и соединенной с любой качающейс при нажатии клавиши частью А механизма пишущей машины, и пружинного выключател Б, соединенного с коллектором Д электродвигател Г и замыкающего ток батареи при качании подвижной части А машины .The proposed device for determining the speed of operation on a writing machine, the circuit of which is shown in the drawing, consists of a galvanometer K connected to the clamps of the dynamo 3 driven by an electric motor G, a battery B supplying an electric motor and a part A of the writing mechanism wobbling machine, and the spring switch B, connected to the collector D of the electric motor G and closing the battery current when the movable part A of the machine is swinging.
В зависимости от частоты включени тока, т.-е. от частоты ударов по клавиатуре пишущей машины, электродвигатель Г развивает ту или иную скорость вращени , передает эту скорость динамомащине, а сила выработанного ею тока указываетс гальванометром. Таким образом, отклонение стрелки гальванометра послужит указателем скорости письма.Depending on the frequency of the current, i.e. from the frequency of strikes on the keyboard of the writing machine, the electric motor G develops one or another speed of rotation, transmits this speed to the dynamo, and the strength of the current generated by it is indicated by a galvanometer. Thus, the deviation of the arrow of the galvanometer will serve as an indicator of the speed of the letter.
Предмет патента.The subject of the patent.
