Abstract

145,500. Daimler-Motoren-Ges. Feb. 16, 1916, [Convention date]. Radiators, aircraft, motor-car, &c.-Relates to screens for controlling the flow of air through radiators, and consists in a roll-up flexible screen fixed at one end and mounted on a free roller at the other end, so that the screen may be wound up or unwound by moving the roller bodily across the front face of the radiator, thereby avoiding the resistance to movement of the screen due to air pressure. Two similar screens b, b<1>, Fig. 1, are secured at their outer ends b<2>, b<3>, to rigid parts, and are mounted at their inner ends on spindles c, c', which are guided in slots d, d<1>, Fig. 2, and are fitted with pinions f, f<1> engaging racks g, g<1> set at an inclination towards the centre of the radiator. The spindles may be moved along the racks and guides by means of an endless cord or wire h passing over guide pulleys i, i<1>, i<2>, and through eyelets on the spindles. The cord is guided over a straight or curved rack k, Figs. 4 and 5, within reach of the driver, and may be held in any adjusted position by means of a lug n on a spring pin p fitted with a handle o to which the cord is secured. The screen may be composed of wood veneer strips on a fabric backing.
