Abstract
421,784. Locating-devices for marking- out work. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE, 8, Rue des Vieux Granadiers, Geneva, Switzerland. June 9, 1934, No. 17170. Convention date, Sept. 29, 1933. [Class 61 (ii)] In a locating and spotting machine, a centre punch 2 and a locating microscope form a unit and the punch, Fig. 1, shown in operative position, may be raised after use to a position wherein a projection 8 rides on the guide 10, whereupon the microscope, consisting of eyepiece 3, cross wires 4, object glass 5, prism 7, and mirror 6 may be used to observe the place occupied by the point of the punch in its working position. In a modification, the optical axis of the microscope is vertical and the lower portion of the punch is cranked so that it may be located on the optical axis in the working position or swung aside when the microscope is to be used.
