Abstract

649,384. Hatch covers. MACGREGOR, R., and MACGREGOR, J. July 6, 1948, No. 18088. [Class 113 (i)] In a hatch covering installation comprising cover sections 4a, 4b, 4c, 4d, each balanced about a pivot roller 8, the end section 5 having a dummy pivot roller 9, each cover having eccentrically mounted fore wheels 6 and aft wheels 7 for supporting it on a pair of parallel runways 1, the end section 5 has a haulage rope 13, pull on which moves the section towards the stowing end, thereby pushing along the preceding sections, the wheels 6 running down a ramp 12 and the wheels 7 running up a ramp 11 to " break " the joint between them, the pivot rollers 8 rolling on tracks 10, and the sections taking up a vertical up-ended stowing position until a pivot 17 on the end section engages sockets 18 mounted on the insides of tracks 10 to bring this section to its stowing position. The pivot roller 9 and rollers 8 are connected by a chain 15 so that when the stowed end section 5 is moved towards its normal hatch closing position it will cause the other sections to be pulled along with it. A duplex type of joint between the sections is described comprising two separate masses of packing material, one housed on one cover section and the other on the adjacent end of the next cover section. Specification 315,557, [Class 113 (i)], is referred to.
