Abstract

19,924. Sarto, C. L. Sept. 7. Plane tables.-Drawing-sheets for use in planetable surveying are graduated with squares and with a circle the centre of which represents the observing station, the alidade for use with these sheets being provided at one end with a vernier for use with the angular graduations of the circle. Fig. 3 shows the method of graduating the sheets 9, and Fig. 4 shows the alidade, which is provided with a needle 13 at the zero of the distance scale 12, this needle forming the pivot of the alidade on the sheet. The alidade is provided with a vernier 11 at one end for use with the graduations of the circle on the sheet 9. Grooves 14, 15 are provided in the alidade for the reception of reading-microscopes. By the aid of the vernier 11, the azimuthal bearings of objects are plotted on the sheet 9, and the distances of these objects from the station point are plotted by the aid of the seale 12. Several of these sheets may be connected together to give a general plan of a survey.
