Abstract

463,778. Viewing-apparatus. BUSCH AKT.-GES., E., and MARTIN, K. Oct. 24, 1936, No. 28980. [Class 97 (i)] [Also in Group XI] In a combined pocket torch and magnifier the magnifying lens is arranged on one side of the instrument between the battery and reflector of the torch, allowing observation through a corresponding opening on the opposite side of the casing. As shown the torch consists of the bulb e, the reflector f, and lens g. For illumination with the magnifier the bulb h is used. The switch contact p is operated by the knob k. When the catch o is engaged with the notch l the current is fed to the bulb e ; when engaged with the notch n it is fed through the strip r to the bulb h. When the magnifier lens b is in use the instrument is placed on the object c which is observed through the opening d.
