Description
Предлагаемый прибор предназначаетс дл выверки хода вниз клавишных и др. рычагов пишущих и т. п. машин, что существенно важно дл урегулировани рабочего хода ответственных частей .машины, имеющих качание околО своих осей.The proposed device is intended for alignment of the downward movement of keyboards and other arms of writing and so on machines, which is essential for regulating the working stroke of the responsible parts of the machine, having a swing around its axes.
На чертеже фиг. 1 изображает боковой вид прибора, фиг. 2-вид в плане.In FIG. 1 is a side view of the device, FIG. 2 is a plan view.
Прибор состоит из закрепленного в подставке 7 коленчатого штатива 2, по вертикальному стержню которого ходит стрелка-указатель 6, закрепл ема на стержне, напр., разрезным зажимом 5 с барашком 9. На конце горизонта:чьного колена штатива в гнезде 70 ходит вверх и вниз линейка 4 со шкалой, удерживаема в гнезде помощью накладки 3 с винтом 8.The device consists of a cranked support 2 fixed in a support 7, on a vertical rod of which an arrow 6 moves, fixed on a rod, for example, by a split clip 5 with a thumb 9. At the end of the horizon: the tripod bend in socket 70 goes up and down ruler 4 with a scale held in the slot using the lining 3 with the screw 8.
Дл измерени опускани (глубины хода), напр., клавиши пишущей машины , прибор устанавливаетс р дом с клавиатурой машины; клавиша подводитс под градуированную литейку 4 (фиг. 1). и последн осторожно опускаетс сверху на кнопку 77 клавиши , после чего линейка 4 задерживаетс в свое.м положении нажимом винта 8 на планку 3. Затем указатель-стрелка б устанавливаетс на нуль измерительной линейки 4, и кнопка клавиши 7 / нажимаетс , тогда величина опускани , из.меренна от опустившегос за клавишей нул линейки 4 до иглы указател б, и дает амплитуду хода или качани клавип:ного рычага.To measure the descent (depth of stroke), for example, of a typewriter key, the instrument is placed next to the keyboard of the machine; the key is brought under the graduated casting 4 (Fig. 1). and the latter gently lowers the button 77 on top of the key, after which the ruler 4 is held up in its own position by pressing the screw 8 on the bar 3. Then the pointer-arrow b is set to the zero of the measuring line 4, and the button of the button 7 / is pressed, then the lowering value The measurement is measured from the line 4 that lowers behind the key zero to the needle of pointer b, and gives the amplitude of the stroke or swing of the clavier: th lever.
