Abstract

11,415. Rosenbaum, B. May 16. Periscopes.-The head b only of the periscope tube proper a projects beyond the outer protecting-tube e, to which it is connected by a flexible water-tight joint k of rubber &c., which is tightened automatically or by a relative movement between the tubes on submersion. When the head is not submerged, the joint is relaxed and the tube a can be easily rotated. If the top is broken, whichever way the sleeve q is turned one of the valves v, w seats on the seating v' and prevents ingress of water.
