Abstract

725,443. Gas-tight access covers. MANNESMANN AKT.-GES., TANNERBAUER, C., and TRAUTMANN, H. March 4, 1953, No. 6065/53. Class 107. A gas-tight closure for an underground airraid shelter consists of a frame 2 set in concrete at ground level and a cover plate 5 hinged at 7 to open inward. Packing 4 provides the gastight seal. A locking lever 10 pivoted at 9 secures the cover in the closed position and is arrested by a stop 15. A grating (not shown) can be fitted on the flanges 12.
