    • 554,731. Filling tanks etc.; funnels. ANGLOSAXON PETROLEUM CO., Ltd., and WILSON, R. Jan. 14, 1942, No. 573. [Classes 21 and 125 (ii)] In order to prevent the unauthorized syphoning off of the contents of petrol tanks and other liquid containers, the filling neck of the tank is provided with a filling tube positioned therein and having restricted openings for the delivery of liquid into the tank and with a part or attadhiment which is normally biassed to expand or open out, is held contracted while the filling tube is inserted in the neck, and expands or opens out when it passes beyond the bottom of the neck and prevents removal of the tube. As shown the tube 1 has a closed end 2 with perforations 3 in the adjacent wall and a pair of pawls 5 pivoted on bolts 6 in an extension 4 on the end 2 of the tube 1. extensions of the bolts limit the downward movement of the pawls. When the tube is inserted in the filling neck 7 the pawls ride along the inner wall of the neck until they reach the bottom end thereof when they open out and prevent removal of the tube. The tube is swaged at the top 9 to rest on the top of the neck 7 and a resilient ring 10 engaging the neck prevents chattering.
