Abstract

548,613. Vehicle lamps. HARTLEY, V. Oct. 6, 1941, No. 12882. [Class 75 (iv)] A mask or screen for vehicle and other electric lamps comprises a number of louvres 5 having upwardly projecting edges 6 each formed at the rear of its side edges with gaps 7 to engage U-sectioned gapped clamping members 11 and at its front edge with an upwardly projecting tongue 10 passing through a semicircular aperture 9 in the louvre above. The parts are soldered or welded together. The louvre assembly is supported in front of a diffusing glass plate 20 at the centre of a back plate 1 substituted for the usual glass front of the lamp by a hook ended member 13 depending from a cowl 4 welded to the plate 1. The top louvre is spaced from the cowl 4 by a member 15 and the louvre assembly is stiffened by an arched member 12 inserted through the apertures 9. Flanged side cheeks 16 spot-welded to the plate 1 carry strips 18 formed with hooks 19 engaging the members 11. A stiffening member 17 may be arranged below the lowest louvre 5. The louvres are formed with upwardly-pressed flanges 8 disposed at such an angle as to prevent direct rays issuing upwardly. Upwardly directed reflected rays are prevented by the flanges 6, 8 and by coating the louvre assembly by a suitable matt pigment. Specification 536,226 is referred to in the Provisional Specification.
