    • 1,085,924. Combined seat walking stick and periscope. E. R. HILL and C. DAVIS. Aug. 8, 1966 [Aug. 20, 1965], No. 35729/65. Headings A4H and A4P. A combined seat-walking stick and periscope consists of an objective reflecting surface 12 provided adjacent to the 'bottom' end of the stick and a viewing reflecting surface 15 adjacent to the seat end wherein provision is made for setting and retaining the objective reflecting surface in a functioning position when required and of locating it in an out of action position when not in use. The objective reflecting surface is suitably mounted on a frame, seated on a hinge attached to the stick, provided with flats 13a and 13b with which a spring pressed plunger 13 cooperates to retain the objective reflecting surface in a permissible position. The viewing reflecting surface may be fixed or suitably hingedly mounted. A hooded screen may be incorporated into the objective reflecting surface to minimise glare.
