Frederick Woodward Bransox, of Leeds, in the County of York, Pharmaceutical Chemist, for “Improvements in the construction of photographic cameras.”—Dated 26th January, 1885. The Patentee says— The object of my improvements is to provide a more con venient arrangement of adjusting photographic cameras for focussing purposes. For this purpose I provide within the base board thereof a frame, fitted so as to slide longitudinally there in. This frame is moved outwards or inwards by a pinion actu ated by the operator and gearing into the rack under the afore said framework. By sliding the framework outwards' au ex tension of base is provided. Above this framework the expand ing portion of the photographic camera is placed. On the upper surface of the framework is provided another rack, into which is geared a pinion mounted in bearings applied below the body of the camera. By this arrangement of rack and pinion the operator may expand or contract the photographic camera for focussing purposes. Patents Granted in America. 331,385.—John H.
