Abstract 1,040,113. Optical apparatus. J. I. YELLOTT and B. C. BUTLER. Feb. 10, 1964, No. 5476/64.. Heading G2J. [Also in Division A5] Optical examination apparatus comprises an erecting telescope having its objective lens 7 mounted in a slidable tube 8 and offset relative to the eyepiece 6, a trigger 4 operatively connected between the objective and a handle 3 for focusing the telescope, a spotlight 2, a rechargeable dry cell 17 in the handle and a battery charging circuit 19 carried by the handle. Switch means 23 for the spotlight is mounted near the handle. An erecting prism 9 between the objective lens 7 and the eyepiece 6 displaces light passing axially through the objective lens so that it passes axially through the eyepiece. The objective lens in the tube 8 is axially slidable on operating the trigger 4 against a spring 28 to focus the telescope. The changer device 19 may be connected to an alternating current supply through terminals 22 and includes a full-wave rectifier (Fig 3 not shown) and a resistance. The telescope may be monocular or binocular.
