Resumen
(EN)

The new instrument is a three piece frame which folds into a compact, hand carried device and when opened forms a track spanning frame. In its open position the frame carries on its midsection an electronic levelmeter and the track gage meter or indicator. PAL The main frame consists of four arms. Two of these arms are hinged to fold on themselves for carrying and opening into a straight line for making measurements of gage and level. The other two arms fold back onto the first two for carrying and open at a predetermined angle to support the first mentioned arms in a perpendicular relationship to the track being observed. PAL Under the three outer ends of the arms are feeler contacts. The two on the angled arms are fixed to ride on the inner edge of one of the tracks being measured. A third feeler contact is carried under the end of the single and oppositely extended arm. This third contact is moveable to contact the inner edge of the second track and is coupled to a gage monitoring device to monitor the gage of the two rails under the three arms of the device of my invention, level monitoring means is carried on one of the arms.
