Description

В ТОЧНЫХ стрелочных измерительных приборах правильный отсчет показаний достигаетс  совмещением трех точек: 1)ножастрелки, 2) его отражени  в зеркале и 3) соответствующего делени  шкалы. При применении прибора без зеркала, т-е. в случае отсчета лишь по концу стрелки и делению шкалы, всегда возможны ошибки. С другой стороны, применение зеркальной шкалы значительно усложн ет прибор. Предлагаемое изобретение имеет целью дать возможность производить правильный отсчет с достаточной точностью исключительно по стрелке без применени  зеркальной шкалы. Устройство заключаетс  в следующем . Расплющенный конец стрелки делаетс  раздвоенным в плоскости, перпендикул рной к плоскости шкалы. Таким образом, отсчеты производ тс , как указано в начале, по совмещению трех точек с тою разницей, что этими трем  точками  вл ютс  две точки на стрелке и нужное деление шкалы.In ACCURATE needle measuring devices, the correct reading of the readings is achieved by combining three points: 1) a knife-arrow, 2) its reflection in the mirror, and 3) an appropriate scale division. When using the device without a mirror, i.e. in the case of counting only by the end of the arrow and the division of the scale, errors are always possible. On the other hand, the use of a mirror scale complicates the instrument considerably. The present invention is intended to enable the correct reading to be carried out with sufficient accuracy solely along the arrow without using a mirror scale. The device is as follows. The flattened end of the arrow is forked in a plane perpendicular to the scale plane. Thus, the counts are made, as indicated at the beginning, by overlapping three points with the difference that these three points are two points on the arrow and the desired scale division.

На чертеже фиг. 1 и 2 изображают в двух проекци х конец указател  прибора; фиг. 3 и 4-видоизменение этого указател .In FIG. 1 and 2 depict in two projections the end of the instrument pointer; FIG. 3 and 4 modification of this index.

Конец указател  выполнен в виде раздвоенного ножа таким образом, что нижн   ветвь, обращенна  к шкале, перпендикул рна к плоскости шкалы, а друга  более коротка  ветвь параллельна последней и снабжена в средней части чертой или прорезом. Таким образом, при правильном отсчете острие ножа нижней ветви должно совпадать с делением шкалы и указанной чертой или прорезом.The end of the pointer is made in the form of a bifurcated knife in such a way that the lower branch facing the scale is perpendicular to the scale plane, and the other shorter branch is parallel to the latter and is provided in the middle part with a dash or slot. Thus, if the knife edge of the lower branch is correctly counted, it should coincide with the scale division and the indicated line or slit.

На фиг. 3 и 4 изображено видоизменение приспособлени , при котором конец указател  выполней в форме рамки, перпендикул рной к плоскости шкалы.FIG. Figures 3 and 4 show a modification of the tool, in which the end of the pointer is in the form of a frame perpendicular to the scale plane.

Одна из сторон этой рамки вырезана таким образом, что при отсчете обе оставшиес  верхние части рамки были на одной линии с видной сквозь прорез серединой нижней части. При этом дл  удобства в верхней стороне может быть нат нута нить, облегчающа  отсчет.One of the sides of this frame is cut in such a way that, when readout, the two remaining upper parts of the frame were in line with the middle of the lower part visible through the slit. In this case, for convenience, a thread may be stretched on the upper side to facilitate counting.

Предмет изобретени .The subject matter of the invention.

1. Приспособление дл  отсчета показаний электроизмерительных приборов, отличающеес  тем, что конец указател , предназначенного дл  отсчета делений шкалы, раздвоен и одна ветвь этого раздвоенного конца, обращенна  к шкале,1. A device for reading the indications of electrical measuring instruments, characterized in that the end of the pointer, intended for counting the graduations of the scale, is bifurcated and one branch of this split end that faces the scale,
