Abstract: 253,991. Marks, E. C. R., (Studebaker Corporation). March 23, 1925. Wind or like screens. - The pivotally mounted windshield 15 of a motor vehicle, adapted to be moved into one of three positions A, B or C, is provided at its lower edge with a flexible blade member 30 adapted to co-operate in the B and C positions with one of two abutments members 26, separated by a perforated web 27 and mounted on the body crossmember 20. With the windshield in position B, air is prevented from entering the vehicle, whilst, in position C, air passes through the perforated web 27, a portion passing downwardly under the cowl 19 in front of the instrument board 18 and into the vehicle body whilst the remainder passes upwardly over the upper portion 25 of the instrument board and against the rear face of the windshield and serves the additional purpose of eliminating any fog or moisture which may have collected on the inside surface of the windshield. In position A, a greater amount of air is allowed to enter the vehicle both beneath the cowl 19 and over the portion 25 of the instrument board. In order to prevent entry of rain with the air a reinforcing trough member 31, Fig. 2, or 35, Fig. 10, is secured to the instrument board 18, the trough member conforming to the transverse curve of the cross member 20 and being formed at each end with a collecting pocket 32, Fig. 8, provided with a spout 33 which receives a pipe 34 leading to a point below the floor of the vehicle. A flexible blade secured at each side of the windshield frame 29 also co-operates with the inside laces of the door posts 22 to prevent rain laden air from entering the vehicle with the windshield in either position B or C. The windshield operating means may comprise a worm 39 on a horizontal shaft 40, Figs. 2 and 3, carried by a bracket 37, 38 secured to the member 20, the shaft 40 being operated by a handle 41 from inside the instrument board. The worm 39 meshes with worm gears 42 on shafts 43 surrounded by coil springs 49 and carrying at their upper ends arms 44 having at their outer ends pins 45 adapted to engage is slots 46 in the U- shaped bracket 47, Fig. 5, which is secured to the rear face of the windshield frame 29. Bow springs 48 in the bracket 47 bear against the pins 45 to prevent rattling. Rotation of the handle 41 moves the arms 44 from the full line position, Fig. 3, which corresponds to position C of the windshield, to the dotted line position corresponding to position A. In the modified operating means shown in Figs. 10 and 11, a two-part bracket 50 having rearwardly extending flanges 51 is secured to the member 20. Journaled in and between the flanges 51 is a screw member 52 with operating member 55 and a shaft 53, the upper end of which carries an arm 44 with headed pin 45. The member 52 and shaft 53 are connected by a block member 59, Fig. 13, having a threaded opening 60 for the member 52 and an opening 61 in which are provided radially projecting keys 62 adapted to engage in spiral grooves 58 in the shaft 53. Rotation of the member 52 causes the member 59 to be raised or lowered. the shaft 53 and arm 44 being turned so as to open or close the windshield.
