Robinson's Disc on a Torpedo Director Pattern 2390[1]
Robinson's Disc was a disc that could be added to a British Torpedo Director to permit the enemy's inclination to the line of sight to be read off directly.[2]
It appears to be, or to have been developed from an unnamed 4 inch diameter disc described in the Annual Report of the Torpedo School, 1914, apparently conceived and first used aboard Blonde.[3]
The purpose was to enable a director setting to be passed to the director officer wholly dependently from the course of the firing ship or the bearing of tube, obviating the need for constant director alterations. By 1915, they were being manufactured to be supplied for all 2390, 2390a and 2380 directors, replacing Longmore's Discs on the 2380 (which showed crossing inclination to the torpedo bar).[4]
